1.0 OBJECTIVE
This documentation serves as a guideline to be adhered by Licensed Land
Surveyor (JTB) appointed by applicant or contractor prior to submission of digital
data, plan or map of any utility, underground utility and digital data to Pengurusan
Air Selangor.
The objective is to ensure Pengurusan Air Selangor as a utility owner received
the plan, and digital data comply to the standard set by the department of Survey
and Mapping, Malaysia (JUPEM) strengthen with additional water supply services
parameter set by us.
2.0 BACKGROUND
Reliable underground utility mapping information is very crucial in managing
development. In conjunctions to increasing number of underground utility damages
due to catastrophic instance resulting disruption of utility services eventually, on
24th August 1994, Cabinet of Malaysia has decided that the department of Survey
and Mapping, Malaysia (JUPEM) shall undertake the responsibility of maintaining
a repository of all underground utility data.
Standard of utility mapping had been established by JUPEM in year 2006, 2007
and 2013 through it’s :
• Garis Panduan mengenai Pemetaan Utiliti bawah Tanah
(Pekeliling KPUP Bil 1 Tahun 2006)
• Garis Panduan Ukuran Pepasangan Utiliti
(Pekeliling KPUP Bil 1 Tahun 2007)
• Garis Panduan Pengukuran Jajaran Laluan Utiliti Baru
(Pekeliling KPUP Bil 1 Tahun 2013)
(Appendix 1 to 3)
2
These standards later enforced by Kementerian Kesejahteraan Bandar,
Perumahan dan Kerajaan Tempatan in year 2014 through it’s:
• Garis Panduan Pelaksanaan Pengukuran Keatas Jajaran Utiliti
Bawah Tanah Semasa Pemasangan
(Pekeliling Ketua Setiusaha Kementerian Kesejahteraan Bandar, Perumahan dan
Kerajaan Tempatan, Bil 7 Tahun 2014)
(Appendix 4)
The circular clearly define standards are to be followed by all Pihak Berkuasa
Negeri and Pihak Berkuasa Tempatan as quoted below:
“Pihak Berkuasa Tempatan hendaklah memastikan bahawa semua utility
bawah tanah baharu yang dipasang melalui pengorekan terbuka atau melalui
penggerudian berarah (horizontal directional drilling: HDD) diukur oleh
Juruukur Tanah Bertauliah semasa pemasangannya. Ketetapan ini juga
hendaklah dijadikan syarat kelulusan dalam Kebenaran Merancang. “
(Item 3: Garis Panduan Pelaksanaan Pengukuran Ke Atas Jajaran Utiliti Bawah Tanah Semasa
Pemasangan)
“Juruukur Tanah Bertauliah hendaklah menghasilkan data dan pelan tersebut
dalam bentuk GIS-ready dengan format dan spesifikasi yang telah ditetapkan
oleh JUPEM dan mematuhi Malaysian Standard 1759”
(Item 4.3 (ii) : Garis Panduan Pelaksanaan Pengukuran Ke Atas Jajaran Utiliti Bawah Tanah Semasa
Pemasangan)
Pengurusan Air Selangor as one of the parties in Kebenaran Merancang,
therefore, extends this JUPEM standard along with additional water supply
services parameter; to be met by any contractor or applicant for any maps, plan
or digital data submission to us.
3
3.0 CURRENT ISSUES AND SHORTCOMINGS
In current practice, not all construction works deployed as per design drawing plan.
Changes are inevitable due to unforeseen construction works circumstances.
Consequently, it may impact underground utility alignment.
Changes of alignment during construction without proper survey record keeping
would only decrease the spatial data quality if the changes were not later translated
to as-built drawing.
Inaccurate information submitted through As-built drawings eventually resulted to
inaccurate GIS data base.
Occasionally we also received as-built drawings submissions which are not in the
true coordinate system (geo-referenced). It’s time consuming to later rectified
these drawings.
As a utility owner, Pengurusan Air Selangor oblique to furnish underground utility
information together with its related metadata at quality levels A, B, C and/or D to
JUPEM for inclusion into National Underground Utility Database. (Pangkalan Data
Utiliti Bawah Tanah Kebangsaan - PADU).
The consequences of having a non validated as-built drawings submissions as GIS
input with much accuracy and quality issues prevent us from performing our duty.
By imposing this JUPEM standard along with additional water supply services
parameter; to be met by any contractor or applicant for submission of any maps,
plan or digital data to us, Pengurusan Air Selangor putting a stop to the cause of
data reliability issues and shall only receive complied as-built drawings.

GARIS PANDUAN MENGENAI PEMETAAN UTILITI BAWAH TANAH
1. TUJUAN
Pekeliling ini bertujuan untuk memaklumkan tentang garis panduan yang
memperuntukkan ketetapan-ketetapan yang telah dibuat mengenai pemetaan
utiliti bawah tanah bagi maksud menyelaras serta menyeragamkan amalan-
amalan yang berhubung kait dengan aktiviti tersebut di negara ini.
2. LATAR BELAKANG
Jemaah Menteri yang bersidang pada 24 Ogos 1994 antara lain telah bersetuju
supaya Jabatan Ukur dan Pemetaan Malaysia (JUPEM) dipertanggungjawabkan
untuk menguruskan pemetaan utiliti seluruh negara. Keputusan ini adalah
selaras dengan hasrat Kerajaan untuk mengatasi, antara lainnya masalah
gangguan perkhidmatan akibat kerosakan saluran utiliti bawah tanah apabila
2
kerja-kerja pengorekan dilakukan tanpa maklumat lokasi utiliti yang mencukupi
atau dengan menggunakan maklumat yang tidak tepat.
Ke arah melaksanakan pemetaan utiliti bagi memenuhi hasrat Kerajaan yang
dinyatakan di atas, “Standard Guideline for Underground Utility Mapping” telah
disediakan. Ketetapan-ketetapan yang terkandung dalam dokumen ini telah
mengambil kira maklum balas daripada pihak-pihak berkepentingan yang terlibat.
Garis panduan ini telah dibentangkan dan dipersetujui di dalam Mesyuarat
Jawatankuasa Teknikal Pemetaan Automasi dan Pengurusan Fasiliti
(Jawatankuasa Teknikal AM/FM) pada 21 Disember 2005 dan seterusnya telah
diberikan pengendorsan oleh Jawatankuasa Pemetaan dan Data Spatial Negara
dalam mesyuarat ke-57 pada 14 Mac 2006.
3. GARIS PANDUAN PEMETAAN UTILITI BAWAH TANAH
3.1 Tujuan
Pelaksanaan pemetaan utiliti di Malaysia sangat memerlukan kepada
panduan mengenai dasar dan tatacara yang bersesuaian untuk diguna
pakai oleh pihak-pihak yang terlibat. Sebelum ini terdapat isu amalan yang
berbeza-beza daripada pelbagai aspek, termasuklah yang berkaitan
dengan pengutipan, penyimpanan, penyenggaraan, pemaparan dan
perkongsian data utiliti. Di samping itu, wujud juga isu kepelbagaian tahap
kualiti data utiliti yang disediakan dan digunakan oleh agensi-agensi atau
pemilik-pemilik utiliti. Sehubungan itu, garis panduan ini disediakan untuk
menjelaskan dasar dan tatacara yang ditetapkan ke arah menyelaras
serta menyeragamkan amalan-amalan yang berhubung kait dengan
pemetaan utiliti bawah tanah di negara ini.
3
Garis panduan ini terbahagi kepada empat perkara utama iaitu:
(i) Peranan pihak-pihak berkepentingan atau stakeholder dalam
pemetaan utiliti bawah tanah,
(ii) Penetapan tahap-tahap kualiti bagi data pemetaan utiliti bawah
tanah,
(iii) Spesifikasi umum bagi peta utiliti bawah tanah, serta
(iv) Pembentukan dan penyediaan Pangkalan Data Utiliti Bawah Tanah
Kebangsaan (PADU).
3.2 Peranan Stakeholder
JUPEM, juruukur tanah serta pemilik utiliti telah pun dikenal pasti sebagai
stakeholder utama dalam pelaksanaan pemetaan utiliti bawah tanah.
JUPEM memainkan peranan utama selaku agensi pelaksana yang
dipertanggungjawabkan oleh kerajaan. Antara lain, JUPEM berperanan
membangunkan serta menyenggara PADU, menjalankan semakan kualiti
ke atas maklumat utiliti tertentu yang dibekalkan oleh pemilik utiliti serta
membekalkan peta utiliti kepada pengguna, terutamanya kepada pemilik
utiliti.
Juruukur tanah secara umumnya memainkan peranan dalam memberikan
perkhidmatan konsultansi teknikal bagi merancang pemasangan serta
melaksanakan aktiviti pengesanan dan pengukuran pepasangan utiliti,
menasihat pemilik utiliti tentang tahap-tahap kualiti data serta menyedia
dan memperakukan pelan-pelan utiliti yang berkaitan.
Pemilik utiliti umumnya merupakan pihak yang memiliki dan menguruskan
pembekalan utiliti kepada pengguna. Antara lain, mereka
bertanggungjawab melantik serta berunding dengan juruukur tanah
berhubung aspek-aspek melaksanakan aktiviti pengesanan dan
4
pengukuran pepasangan utiliti, memberikan akses kepada data dan rekod
utiliti mereka kepada jurukur tanah serta membekalkan maklumat utiliti
kepada JUPEM.
3.3 Tahap Kualiti Data Utiliti Bawah Tanah
Ketepatan maklumat kedudukan dan jajaran pepasangan utiliti yang
sedang berada di bawah tanah adalah sangat mustahak kepada
kontraktor yang dilantik oleh pemilik utiliti dalam memberikan panduan
bagi memasang pepasangan utiliti yang baru atau menyenggara
pepasangan utiliti yang sedia ada. Oleh itu, tahap kualiti bagi setiap
jajaran pepasangan utiliti bawah tanah perlulah dikenal pasti, dan
seterusnya dinyatakan dalam pelan atau peta utiliti dan pangkalan data
utiliti.
Bergantung kepada ketepatan dan kebolehpercayaan (reliability)
maklumat utiliti bawah tanah, kualiti maklumat tersebut terbahagi kepada
empat tahap, iaitu dari tahap kualiti terendah (tahap kualiti D) hingga ke
tahap kualiti tertinggi (tahap kualiti A). Huraian lengkap mengenai tahap-
tahap kualiti data pemetaan utiliti bawah tanah diterangkan secara
terperinci di Para 4.0 “Standard Guideline for Underground Utility
Mapping” di Lampiran A.
3.4 Spesifikasi umum bagi peta utiliti bawah tanah
Spesifikasi ini disedia dan dimuatkan di dalam garis panduan bagi
menyeragamkan amalan paparan maklumat pemetaan utiliti di dalam peta
cetakan ataupun peta salinan lembut. Spesifikasi ini bersifat umum kerana
mengambil kira amalan-amalan yang sedia ada. Ia memperuntukkan ciri-
ciri peta utiliti seperti sistem koordinat, rangka, kandungan dan maklumat
sisipan peta.
5
3.5 Penubuhan Pangkalan Data Utiliti Bawah Tanah Kebangsaan (PADU)
Penubuhan PADU merupakan salah satu daripada objektif utama
pelaksanaan pemetaan utiliti. Secara umum, pangkalan data ini akan
dibentuk dengan menggabungkan, antara lain data-data berikut:
• Data ukur kadaster,
• Data topografi vektor berskala besar, dan
• Data lokasi serta butiran-butiran lain yang berkaitan bagi pepasangan
utiliti bawah tanah.
Penerangan secara lebih terperinci tentang perkara-perkara yang berkaitan bagi
melaksanakan pemetaan utiliti bawah tanah adalah seperti yang terdapat di dalam
“Standard Guideline for Underground Utility Mapping” di Lampiran A.

STANDARD GUIDELINE FOR
UNDERGROUND UTILITY MAPPING
AM/FM Technical Sub-Committee National Mapping and Spatial Data Committee
i i
PREFACE The continuous economic development generally experienced in this country has resulted in increasing demands for improvement in basic infrastructure facilities such as roads, transportation, utilities and other amenities. One of the often-repeated infrastructural improvements is road widening, and the ensuing relocation of utilities including those laid underground during these road works may result in damage to the underground utilities especially if proper care and systematic work approach are not observed. When these damages occur, delivery of utility services becomes disrupted, citizen’s quality of life becomes compromised, monetary losses confronted and worst, fatal accidents may occur. The Government views these disruptions very seriously and had on two occasions, through Cabinet decisions, directed for the establishment of a centralised underground utility database to be maintained by Jabatan Ukur dan Pemetaan Malaysia (JUPEM) in close cooperation with utility agencies. Orderly management of utility data between JUPEM and utility agencies requires the establishment of agreed mechanisms, procedures and specifications, and the first of these is this Standard Guideline for Underground Utility Mapping document. This guideline covers various aspects of underground utility mapping such as the roles of various stakeholders, classification of underground utility quality levels, generic specifications for underground utility map as well as the creation of underground utility mapping database. It is the culmination of concerted efforts by members of the AM/FM Technical Committee comprising underground utility stakeholders functioning under the auspices of the National Committee for Mapping and Spatial Data, being the responsible body for the coordination of mapping activities in this country. It is hoped that all stakeholders would adopt the noble tenets of this standard guideline in their respective underground utility mapping practices. It is further hoped that this standard guideline would become an important accessory in fulfilling the Malaysian Cabinet’s directive.

STANDARD GUIDELINE FOR UNDERGROUND UTILITY MAPPING 1.0 INTRODUCTION
Maintaining reliable underground utility mapping information is an important task in the development, maintenance and upgrading of underground utility infrastructure. Taking into account the increasing instances of catastrophic damages of underground utilities and disruption of existing utility services resulting from excavation works, the Cabinet, in its meeting on 24th August 1994, has decided that the Department of Survey and Mapping, Malaysia (JUPEM) shall undertake the responsibility of maintaining a repository of all underground utility data, apart from those kept by the various utility agencies.
The data collected will then be provided to relevant parties involved in new underground utility projects to minimise the risks associated with construction activities that may affect existing underground utilities. In order to undertake this new responsibility, JUPEM is expected to embark on the creation and subsequently, the maintenance of the National Underground Utility Database.
This standard guideline is intended to be used by those involved in various capacities in underground utility mapping as well as in maintaining a reliable underground utility mapping information system.
2.0 SCOPE
This standard guideline addresses issues such as (a) the roles of stakeholders, (b) utility quality levels, (c) how utility information can be obtained, and (d) the formatting of the utility map.
This document also addresses the requirement for the National Underground Utility Database, which stores related utility data that can be made available to utility owners and all other relevant parties whenever existing underground utility information is required.
2 2
3.0 THE ROLES OF UTILITY OWNER, SURVEYOR, AND JUPEM IN
UNDERGROUND UTILITY MAPPING 3.1 Utility Owner
The utility owner should: 3.1.1 Identify the scope of work and the specifications of deliverables for the
surveyor and finalise work specifications with the surveyor.
3.1.2 Provide assistance when necessary in enabling a surveyor to obtain access to existing underground utility records.
3.1.3 Involve the surveyor in pre-bid and pre-construction meetings, pre-
selection of contractors, and retain the surveyor to perform plan review.
3.1.4 Notify the surveyor within a reasonable time frame of any suspected deficiencies in the utility depictions at the specified quality level discovered during construction.
3.1.5 Furnish existing underground utility information together with its related
metadata at quality levels A, B, C, and/or D to JUPEM for inclusion into the National Underground Utility Database.
3.1.6 Continually furnish JUPEM appropriate utility installation and relocation
information to enable the said department maintain the National Underground Utility Database as mandated by the Government.
3.1.7 Ensure that all underground utility information for all new projects attain
quality level A. For this purpose, a surveyor shall be engaged to perform as-built surveys during construction and emplacement of underground utilities.
3.1.8 Provide quality level A data to JUPEM for all new underground utility
projects.
3 3
3.2 Surveyor
The surveyor should:
3.2.1 Provide information to the utility owner with regards to potential effects that a new project may have on existing underground utilities.
3.2.2 Advise the utility owner regarding utility quality levels and reliability of
data for each quality level for existing datasets; and the need for acquiring new data if necessary. The costs and benefits associated with obtaining new quality level A data should also be discussed.
3.2.3 Identify and recommend a scope of utility investigations on the basis of
project needs. It may include portions of the project area which may require existing utilities to be investigated and depicted at quality level A.
3.2.4 Recommend specifications of deliverables to clearly distinguish the
various quality levels.
3.2.5 Discuss the steps of acquiring appropriate quality level data throughout the planning and design process of new projects, taking into account project design elements, design timetables, the type of project, the criticality of utility service, etc.
3.2.6 Conduct appropriate data acquisition and survey works and prepare underground utility maps in digital and hardcopy forms together with appropriate supporting documents according to the utility owner’s specification by clearly identifying their appropriate quality levels.
3.2.7 Analyse data with utility owners.
3.2.8 Review plans during the design stage to assess the effects of design
changes to current utility information, where necessary.
3.2.9 Recommend areas of underground utility survey for a quality level upgrade after review. Such an upgrade shall be to quality level A.
3.2.10 Comply with all applicable laws, regulations and guidelines.
3.2.11 Place note on the plans indicating the different utility quality levels for
each underground utility.
3.2.12 Certify the plans that depict existing underground utility data at the indicated quality levels.
3.2.13 Discuss utility installation and utility relocation policies for the utility
owner’s implementation.

• Distribution maps • Transmission maps • “As-built” and record drawings • Appropriate geographic information system databases • Circuit diagrams
4.1.3 Analyse records for:
Availability of additional information Duplicate information and accuracy of such duplicate information Need for further details from utility owner
4.1.4 Prepare utility composite drawing in digital and hardcopy. The surveyor should also make professional judgements regarding the validity and location of topographic features on records versus current topographic features (when available) and conflicting references of utilities.
4.2 Quality Level C
Typical tasks to be undertaken by the surveyor leading to utility quality level C are:
4.2.1 Perform tasks as prescribed for quality level D data acquisition. Quality
level C and D tasks do not necessarily need to be performed in any particular order.
4.2.2 Locate surface features on existing records and ground surface that
are surface appurtenances of existing underground utilities.
4.2.3 Survey such features if they have not been previously surveyed. Otherwise, check the accuracy of survey and completeness of information for applicability with the new project.
4.2.4 Correlate relevant utility records to the surveyed features, taking into
account the shape, size and characteristics of these surface features.
4.2.5 Resolve discrepancies when records and features do not agree. This may be done by showing the underground utility feature at quality level D, hence disregarding a surveyed surface appurtenance of unknown origin. Consultation with utility owner may be required to resolve the discrepancies.
6 6
4.3 Quality Level B
Typical tasks to be undertaken by the surveyor leading to utility quality level B are:
4.3.1 Undertake tasks as described for quality level C data acquisition.
Quality level C and B tasks do not necessarily need to be performed in any particular order.
4.3.2 Use an appropriate set of surface geophysical methods to search for
underground utilities within the project area or to perform a utility trace for a particular utility system.
4.3.3 Interpret the surface geophysical data.
4.3.4 Mark and indicate the location of underground utilities on the ground
surface for subsequent survey. Care should be taken to differentiate markings placed on the ground for design purposes from those used for damage prevention purposes.
4.3.5 Survey all markings that indicate the presence of an underground utility
to the accuracies and precision dictated by the project’s survey control.
4.3.6 Depict all designated underground utilities following the general guideline as presented in Section 5.0. Depiction may be accomplished via computer-aided design and drafting or geographic information systems.
4.3.7 Correlate the designated underground utilities’ portrayal with existing
utility records and/or surveyed appurtenances to identify underground utilities that may exist but were not able to be designated.
4.3.8 Resolve differences between designated underground utilities and
existing underground utility records as well as with surveyed appurtenances. A choice will have to be made between undertaking additional surface geophysical surveys and depicting the underground utilities at a lower quality level. The survey may be done at appropriate points to quality level A; and judgement will have to be made to verify whether a designated underground utility and that existing in the utility record are actually identical, though they do not seem to be geographically coincident.
4.3.9 Recommend to the utility owner to take additional measures to resolve
differences if they still exist such as using additional or different surface geophysical methods, exploratory excavation, or an upgrade to quality level A data.
7 7
4.4 Quality Level A
Typical tasks to be undertaken by the surveyor leading to utility quality level A are:
4.4.1 Perform tasks as described for quality level B data acquisition. Quality
level B, C, and D tasks do not necessarily need to be performed in any particular order.
4.4.2 Use an appropriate method of data acquisition that will achieve the
accuracies and precision required by the project. These accuracies are at 10 cm or better in vertical as well as in horizontal. Exposure and survey of the underground utility at each specific location where quality level A data are to be obtained may be performed whenever necessary.
4.4.3 Calibrated survey equipment and surface geophysical detection
equipment will be used to acquire quality level A data in order to ensure that the expected accuracy of measurement is achieved. If need be, excavate test holes to expose the underground utility to be surveyed without affecting the underground utility to be measured. Exposure can be performed by minimally intrusive excavation method. Data collection during underground utility construction may eliminate the need for excavation, as it is already exposed.
4.4.4 Determine the following:
a) horizontal and vertical location of the top and/or bottom of the
utility referenced to approved JUPEM’s datum; b) elevation of the existing underground utility at a test hole,
whenever necessary, referenced to the project survey datum; c) outside diameter of the utility and configuration of non-encased,
multi conduit systems; d) utility structure material composition, when reasonably
ascertainable; e) benchmarks and/or project survey data used to determine
elevations; f) paving thickness and type, where applicable; and g) other relevant information.
4.4.5 Resolve differences between depicted quality level A data and other
quality levels referring to the same underground utility. This can be done through additional surface geophysical survey or by depicting the adjacent or nearby data points for that underground utility at a lower quality level. On the other hand, utilities already depicted at quality level B, C, or D may also be re-depicted to coincide with the more accurate quality level A data provided upgrade surface geophysical survey is undertaken at appropriate points.
8 8
5.0 Equipment Calibration
All survey and surface geophysical detection equipment used to acquire quality level A data shall be appropriately calibrated to ensure that it is in good working order as well as to enable it to achieve the required accuracy as specified in this standard guideline.
6.0 DELIVERABLES FORMATTING 6.1 General
The main deliverable of an underground utility mapping is the map, whether in hardcopy or digital form. This part of the standard guideline describes some general guidelines on the preparation of the map either for general exchange of information or for inclusion into the National Underground Utility Database.
6.2 Basic Deliverable
The basic deliverable is in the form of mapping file and hardcopy sheet that contain utility information in plan view for data with quality levels A, B, C, and D. Quality level A data shall be furnished with additional information such as written reports and test hole summary sheet. This standard guideline does not address the quality of vertical information other than for quality level A data.
6.3 Quality Level Attributes
6.3.1 General
The quality level attribute of an underground utility feature is the most important information aside from its alignment or presence in a utility map. As such due care should be taken to precisely indicate the quality level of an underground feature especially in hardcopy maps given the fact that in any congested corridor, the horizontal and vertical separation between utility features could be reduced to several decimetres, and at plotting scale such separation may be difficult to discern.
Usage of the following cartographic elements can help in ensuring a reliable indication of the quality level of underground features.
9 9
6.3.2 Line Code and Style
Use of line code and style is one of the methods to differentiate between the various quality levels. The line code and style can differentiate not only quality levels but also utility type and/or ownership.
6.3.3 Labelling
This is also one of the methods of differentiating between the quality levels, utility type, ownership, date of depiction, accuracy of surveyed appurtenances, end points of any utility data, active, abandoned, or out-of-service status, size, condition, number of jointly buried cables, and encasement.
6.3.4 Symbol Embedding
Symbol embedding can also be used to indicate the different quality levels of underground utility data.
6.3.5 Colour
Colour may be used to indicate utility type and can be used in conjunction with other methods.
6.3.6 Line Weight
Line weight can be used at actual scale to depict the size of the utility. However, it has the effect of obscuring other data if the line size is large.
6.3.7 Layer
This method is to be used to portray various attributes. For example, quality level A data could be on one layer, quality level B data on another, and etc. All layers must be turned be on to present the complete utility information particularly in a geographic information system.
6.3.8 Annotation
Annotation should be appropriately used to ensure that it does not obscure other utility data.
10 10
6.4 Utility Depiction Legend
Underground utility map may be provided with a separate utility legend to clearly indicate the methods of quality level differentiation and other utility attributes.
6.5 Parcel Boundaries
Parcel boundaries shown shall be derived from the Digital Cadastral Database (DCDB) currently maintained by JUPEM.
6.6 Lot Numbers
Lot numbers of all parcels as derived from the DCDB shall be shown whenever possible.
6.7 Names of Building, Street, Road and River
Official names of buildings as well as names of streets, roads and rivers shall be shown.
6.8 North Arrow
An arrow-like symbol indicating the direction of the grid north and the true north shall be shown.
6.9 Scale Representation
Since maps must necessarily be smaller than the areas mapped, their use requires that the ratio or proportion between comparable measurements be expressed on the map. This is called map scale and should be the first thing of which the map user becomes aware. Scale should be expressed as a statement of map distance in relation to earth distance or a graphic (or bar) scale or both.
6.10 Map Date
The publication date of the map should be prominently displayed.
11 11
6.11 Marginal Information
Marginal information may among others include such items as section, town, city and state names, scale, north arrow, legend, published date, disclaimer, and map index.
6.12 Disclaimer
Disclaimers are used to limit and define the map author's responsibility for the content, accuracy, and currency of a map. Although some maps may require specialised disclaimers, the following disclaimer represents one suggestion:
"Not to be treated as a map depicting property boundaries”
7.0 CREATION AND MAINTENANCE OF THE NATIONAL UNDERGROUND
UTILITY DATABASE 7.1 Database Design
The National Underground Utility Database shall be created and maintained by JUPEM. The database would be seamless but shall utilise the JUPEM National Map Index for ease of reference and easy data retrieval. The database shall also utilise the MS1759 database schema and will consist of feature layers which include the following:
• Digital cadastral data (providing the primary base map) • Large scale topographic data (providing the secondary base map) • High-resolution satellite imagery (desirable) • Underground utility
7.2 Base Map Development
A base map is a geometric control feature in a digital mapping system that permits many other specialised theme layers to be brought into absolute position by registration on the base map. Certain themes or layers of base map content will be utilised to register the utility themes or layers.
The primary base map will be provided by the Digital Cadastral Database (DCDB) currently being maintained by JUPEM. The database comprises coordinate geometry of every surveyed land parcel generated by keyboard entry of survey accurate data resulting from actual ground surveys. As such it provides the most accurate base map available and suited to be used at a scale of 1:500 or even larger.
12 12
The secondary base map will be provided by a large scale Digital Topographic Database to be newly created by JUPEM at the scale of 1:500 by aerial photography. An interim topographic base map may however be provided in raster using suitable high resolution remotely-sensed imagery.
7.2.1 Paper to Digital Conversion
Many of the existing underground utility maps may be in paper form. There are several methods of converting these paper maps into digital form. Each method must follow certain fundamental principles to be successful. The alternatives of scanning, board digitising and coordinate geometry must be evaluated to determine the most desirable method to be employed for each portion of a mapping project. Most mapping strategies will probably use a combination of conversion methods to provide the optimum conversion strategy for an entire project. Care should be taken to plan each project with adequate time and resources to ensure a final product that will meet the standard of accuracy required.
The following aspects are to be given due consideration:
• The available source documents are legible or restorable. • Source documents are relatively accurate (in scale and
direction). • There is adequate control to locate the map in the real world. • The frequency of the control ensures that all map portions are
fitting properly. • The distribution of the control ensures that there is no distortion
in areas of difficult fits.
Scanners should be of adequate resolution to convert source documents to a pixel size that will support desired accuracy. They should support an adequate number of shading levels to reproduce the detail of the original document to the screen. Additionally, they should be of adequate size to accommodate source material with a minimum of cutting or folding. Digitiser resolution too should support accuracy required. Computer processing and storage must have the capacity to process and store large raster files. The video adapter and monitor of the system must allow clear viewing of digitised materials. The software employed must offer adequate manipulation tools to capture and enhance source documents, as well as friendly enough to ensure consistent, accurate use by trained operators. Software employed too must provide all the tools required to ensure accurate fitting of digitised source to project, apart from facilitating quality control procedures. Operators should be well trained and follow sound conversion procedures. Quality control should be frequent and thorough.
13 13
7.2.2 Accuracy
Map accuracy is the degree toward which any given feature(s) on a map conforms to its true position on the ground. The direct benefit of map accuracy is to ensure accurate spatial representation of mapped features not only on base maps, but also for features included in other utility map themes.
Positional accuracy of underground features is to be of paramount importance, considering the risks associated with low accuracy position determination. This importance is further amplified by the use of very large scale presentation of the National Underground Utility Database and therefore requires that 90% of all randomly chosen samples of well-defined map features shall be within 0.5mm (at scale on the map) of their true planimetric location on the ground while the accuracy in vertical shall be within 10 cm.
7.3 Projections and Coordinate Systems
The following projections and coordinate systems are required for the input, storage, and in particular, the exchange of digital map data. All underground utility maps in Malaysia should be based on the Rectified Skew Orthomorphic (RSO) coordinates, referenced to the Geocentric Datum of Malaysia 2000 (GDM2000) horizontal datum.
7.3.1 Cassini-Soldner State Plane Coordinate Systems
The Cassini-Soldner State Plane Coordinate Systems is currently utilised for cadastral surveys in the states of Peninsular Malaysia. As such the primary base map provided by the DCDB needs to be re-projected onto RSO (Malaya) referenced to GDM2000 for use in utility mapping. These systems are to be used for the input, storage, and exchange of digital map data, as well as for the output of hardcopy maps.
7.3.2 RSO (Malaya) Kertau Datum / RSO (Borneo) Timbalai Datum
The RSO (Malaya) map projection system based on Kertau datum is currently used for topographic mapping in Peninsular Malaysia while the RSO (Borneo) projection system based on Timbalai datum is used for cadastral surveying as well as topographic mapping in Sabah and Sarawak. However, for the purpose of underground utility mapping, the projection systems to be used shall be RSO (Malaya) on GDM2000 and RSO (Borneo) on GDM2000 respectively.
7.3.3 Height Datum
All heights shall be based on the National Geodetic Vertical Datum.
14 14
7.4 Data Exchange Standards
In order to facilitate efficient exchange of underground utility data between the surveyor, utility owner, JUPEM and the data users, the Malaysian geographic information exchange standard namely, MS 1759:2004 Geographic Information – Features and Attributes Codes shall be utilised.
7.4.1 Data Exchange Formats
All common vector data exchange formats supported by Feature Manipulation Engine (FME) software can be used.
7.4.2 Data Exchange Media
Various data exchange media are available, depending on the hardware systems installed at the source and target organisations. The users exchanging data will determine the best media based on available network connections, modem connections, available input and output devices, CD-ROM or other transfer media.
7.5 Metadata
Metadata are commonly defined as the data about data or the data about the processes performed on data. The major uses of metadata are:
i. To provide information about an organisation's data holdings to data
catalogues and clearinghouses; ii. To provide information needed to process and interpret data to be
received through a transfer from an external source; and iii. To maintain an organisation's investment in geospatial data.
In order to facilitate their use, underground utility maps produced shall be accompanied with appropriate metadata which complies with the Malaysian Standard for Geographic Information - Metadata.

APPENDICES
APPENDIX A: GLOSSARY OF TERMS Absolute map accuracy: The accuracy of a map in relationship to the earth's geoid. The accuracy of locations on a map that are defined relative to the earth's geoid are considered absolute because their positions are global in nature and accurately fix a location that can be referenced to all other locations on the earth. Base map: A map showing certain fundamental information used as a base upon which additional specialised data are compiled. Cadastral Database: A database showing the boundaries of subdivisions of land, for the purposes of describing and recording ownership; containing particulars such as land parcel dimensions, its area as well as its unique parcel identification number. Coordinates: Linear or angular quantities that designate the position of a point in a given reference frame or system. Also used as a general term to designate the particular kind of reference frame or system, such as state plane coordinates or spherical coordinates. Coordinate geometry: Automated mapping software that translates the alphanumeric data associated with a survey (distances, bearings, coordinates, etc.) into digital map information for creating and updating a digital cartographic data base. Designating: The process of using a surface geophysical method or methods to interpret the presence of a underground utility and to mark its approximate horizontal position on the ground surface. Also termed as “locating.” Geodetic coordinates: The quantities of geodetic latitude or longitude that define the position of a point on the surface of the earth with respect to the reference spheroid. Geographic coordinates: A system of spherical coordinates for defining the position of points on the earth. The declinations and polar bearings in this system are the geographic latitudes and longitudes respectively. Geographic Information System (GIS): A computerised data-base system for capture, storage, retrieval, analysis, and display of spatial data. Global Positioning System (GPS): Determination of coordinates of points using a network of satellites intended for this purpose. Index map: A map of smaller scale on which are depicted the locations (with accompanying designations) of specific data, such as larger-scale topographic quadrangles.
16 16
Minimally intrusive excavation method: A method of excavation that minimises the potential for damage to the structure being uncovered. Factors such as utility material and condition may influence specific techniques. Typical techniques for utility exposures include air-entrainment/vacuum-extraction systems, water-jet/vacuum-extraction systems, and careful hand usage. Parcel: A single, discrete piece of land having defined physical boundaries and capable of being separately conveyed. Photogrammetry: The art, science, and technology of obtaining reliable information about physical objects and the environment through processes of recording, measuring, and interpreting images and patterns of electromagnetic radiant energy and other phenomena. Projection: A systematic representation of all or part of the surface of a sphere onto a plane. Relative map accuracy: The accuracy of a map in relation to a local survey network that is not tied to the earth's geoid. The accuracy of locations on a map defined relative to a local survey network is considered relative because the positions are accurate only within a certain geographic area covered by the network. Scope of work: All services and actions required of the consultant by the obligations of the contract. State plane coordinate systems: A series of grid coordinate systems prepared by the Department of Survey and Mapping Malaysia for all the states in Peninsular Malaysia, with basically a separate system for each state, based on the Cassini-Soldner projection. Underground Utility Mapping: A branch of mapping practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility condition assessment, communication of utility data to concerned parties, and utility map design. Surface geophysical method: Any of a number of methods designed to utilise and interpret ambient or applied energy fields for the purpose of identifying properties of, and structure within the earth. Such methods typically include variants of electromagnetic, magnetic, elastic wave, gravitational, and chemical energies. Survey datum: The points of reference used to define a specific geographic location in three-dimensional space. Surveyor: A survey officer serving with the Department of Survey and Mapping, Malaysia or the person whose name has been placed upon the register of licensed land surveyors and to whom a license to practice has been issued by the Land Surveyors Board of Peninsular Malaysia, Sabah or Sarawak.

Each of the four existing utility data quality levels is established by the different methods of data collection and interpretation. Utility quality level A: Precise horizontal and vertical location of utilities through the application of appropriate surface geophysical methods using calibrated equipment or if necessary by actual exposure and subsequent measurement of underground utilities, at a specific point. Minimally intrusive excavation may be undertaken to reduce the potential damage to the underground utility installation. Precise horizontal and vertical locations to an accuracy of 10 cm. as well as other utility attributes are shown on plan documents to applicable horizontal survey and mapping accuracy specified in this standard guideline. Utility quality level B: Information obtained using appropriate surface geophysical methods to locate the approximate horizontal position of underground utilities. Quality level B data should be reproducible using surface geophysical techniques at any point of their depiction. This information is surveyed to applicable tolerances defined by the project.

PEKELILING KETUA PENGARAH UKUR DAN PEMETAAN BIL. 1 TAHUN 2007
GARIS PANDUAN UKURAN PEPASANGAN UTILITI
1. TUJUAN
Pekeliling ini bertujuan untuk menyediakan garis panduan mengenai kerja
ukur berkaitan pemetaan utiliti. Ia diharapkan akan menjadi panduan dan
rujukan oleh juruukur-juruukur tanah di dalam menjalankan aktiviti tersebut, di
samping dapat menyeragamkan amalan-amalan yang berkaitan dengan
urusan berkenaan.
2. LATAR BELAKANG
Jemaah Menteri yang bersidang pada 24 Ogos 1994 antara lain telah
bersetuju bahawa Jabatan Ukur dan Pemetaan Malaysia (JUPEM)
dipertanggungjawabkan untuk menguruskan pemetaan utiliti seluruh negara.
Keputusan ini adalah selaras dengan hasrat Kerajaan untuk mengatasi,
antara lainnya masalah gangguan perkhidmatan yang diakibatkan oleh
perbuatan kontraktor yang merosakkan saluran utiliti bawah tanah apabila
melakukan kerja-kerja pengorekan.
2
Sehubungan dengan itu, satu dokumen yang bertajuk “Standard Guideline for
Underground Utility Mapping” (selepas ini dirujuk sebagai Standard Guideline)
telah disediakan dan diberikan pengendorsan oleh Jawatankuasa Pemetaan
dan Data Spatial Negara. Dokumen tersebut memberikan tumpuan kepada
usaha untuk menghasilkan pangkalan data pemetaan utiliti kebangsaan
(PADU) yang lengkap dan berkualiti tinggi serta penekanan kepada aspek-
aspek peranan pihak-pihak yang terlibat dengan pemetaan utiliti, tahap kualiti
maklumat pemetaan utiliti serta spesifikasi umum peta utiliti.
Pekeliling yang disediakan ini pula bertujuan menyediakan garis panduan
untuk kegunaan juruukur tanah dalam menjalankan kerja ukur bagi tujuan
pemetaan utiliti dan ia perlu dibaca bersekali dengan Standard Guideline
yang disebutkan di atas. Antara lain ia memperihalkan tentang kaedah
pengesanan dan prosedur ukuran pepasangan utiliti.
3. JENIS PENGESANAN DAN UKURAN PEPASANGAN UTILITI
Selaras dengan peruntukan tentang aspek kualiti data pemetaan utiliti yang
terdapat di dalam Standard Guideline, pengesanan dan ukuran pepasangan
utiliti dapat dibahagikan kepada dua (2) jenis, iaitu:
(a) Pengesanan dan ukuran bersempena pengesanan geofizikal secara
non-invasive bagi menghasilkan data pemetaan utiliti pada tahap
kualiti B.
(b) Ukuran ke atas pepasangan utiliti bawah tanah yang terdedah seperti
ukuran as-built serta yang seumpamanya bagi menghasilkan data
pemetaan utiliti pada tahap kualiti A.
Walaupun begitu, mungkin timbul keperluan untuk menjalankan ukuran bagi
memenuhi tahap kualiti C. Dalam hal ini, bahagian pepasangan utiliti yang
berada di permukaan bumi (dan terdedah) turut perlu diukur sekiranya belum
diuruskan sebelumnya, sebagaimana diperuntukkan di bawah perenggan
4.2.2 dan 4.2.3 Standard Guideline.
3
3.1 PENGESANAN DAN UKURAN GEOFIZIKAL NON-INVASIVE Pengesanan dan ukuran jenis ini secara umumnya melibatkan
pengesanan pepasangan utiliti bawah tanah yang boleh dijalankan
secara serentak dengan kerja ukur kawalan. Ini diikuti pula dengan
pengukuran pepasangan utiliti bawah tanah, pepasangan utiliti di
permukaan bumi dan butiran topografi.
Dalam menguruskan kerja ini, siasatan dan penentuan kedudukan ciri-
ciri utiliti tertentu (seperti pili bomba, manhole, tiang lampu, pondok
telefon dll.) yang terdapat di permukaan bumi dan bersangkutan
dengan kewujudan utiliti di bawah tanah di kawasan ukuran, hendaklah
dibuat terlebih dahulu.
Prosedur pengesanan dan ukuran ini adalah seperti berikut:
3.1.1 Pengesanan Pepasangan Utiliti Bawah Tanah
Pepasangan utiliti bawah tanah melibatkan penggunaan bahan
dan saiz yang berlainan serta boleh diletakkan pada kedalaman
yang berbeza. Selain itu, persekitaran di mana ia ditanam boleh
berubah-ubah dari satu tempat ke tempat yang lain dan boleh
menjadi padat dengan penempatan pelbagai jenis utiliti.
Keadaan ini menyebabkan kemungkinan timbul keperluan bagi
menggunakan lebih daripada satu teknik bagi mengesan
kedudukannya. Pemilihan teknik yang sesuai adalah penting
untuk memastikan pengesanan utiliti yang berkesan.
4
Secara umumnya, teknik-teknik pengesanan yang boleh
digunakan boleh dikelaskan seperti berikut:
(a) Elektromagnetik
• Pipe and Cable Locator (PCL)
• Terrain Conductivity
• Resistivity Measurements
• Metal Detectors
• Ground Penetrating Radar (GPR)
• Optical Methods
• Infrared (Thermal) Methods
• X-Ray Methods (Penetrating Radiation)
(b) Magnetik
• Magnetometer
- Total Field Measurements
- Gradiometric Measurements
(c) Gelombang Anjal (Elastic Wave)
• Seismic Reflection
• Seismic Refraction
• Acoustic Emission
Walaupun demikian, aktiviti pengesanan pepasangan utiliti
bawah tanah lazimnya melibatkan dua jenis peralatan iaitu Pipe
and Cable Locator (PCL) dan peralatan Ground Penetrating
Radar (GPR), kedua-duanya menggunakan teknik
elektromagnetik.
5
(a) Pengesanan Menggunakan Pipe and Cable Locator
(PCL)
Peralatan PCL biasanya digunakan untuk mengesan
pepasangan utiliti bawah tanah yang diperbuat daripada
logam ataupun sebarang pepasangan utiliti bawah tanah
yang mempunyai rongga seperti paip yang boleh
dimuatkan di dalamnya pengalir logam atau pemancar.
Bagi memastikan ketepatan pengesanan yang lebih baik,
mod pengapitan (clamping) atau sambungan terus (direct
connection) hendaklah digunakan semasa membuat
pengesanan dengan menggunakan PCL.
Setelah dikesan, lokasinya perlulah ditanda pada
permukaan bumi bagi membolehkan kedudukan dan
jajaran pepasangan utiliti tersebut diukur.
Peralatan PCL yang digunakan perlulah berupaya untuk
memberikan nilai lokasi dan kedalaman pepasangan utiliti
pada keselisihan ±5% daripada nilai sebenar.
(b) Pengesanan Menggunakan Ground Penetrating Radar
(GPR)
Peralatan GPR biasanya digunakan bagi mengesan
pepasangan utiliti bawah tanah yang diperbuat daripada
bahan bukan logam seperti asbestos dan plastik. Walau
pun begitu ia boleh juga digunakan untuk mengesan utiliti
berlogam.
6
Sistem GPR yang dikhususkan untuk menjalankan kerja-
kerja pengesanan di bawah tanah pada kebiasaannya
mengandungi komponen-komponen pengutipan data
(antena dan peralatan penawanan data) serta perisian
untuk memproses data radar.
Gabungan antena wajar digunakan untuk
memaksimumkan kapasiti bagi menawan maklumat di
bawah tanah. Penggunaan sistem sebegini mampu
meningkatkan keupayaan pengesanan dan
menyelesaikan geometri yang kompleks. Walaupun
begitu, penggunaan single antenna boleh digunakan
untuk ruang pengesanan yang kecil.
Bergantung kepada kedalaman dan keadaan tanah, julat
frekuensi pada peralatan GPR berikut sepatutnya
digunakan:
Sensor Frekuensi Kedalaman
Frekuensi Tinggi > 1000 MHz < 0.5 m
Frekuensi Sederhana
Tinggi 400 – 600 MHz 0.5 m – 1.5 m
Frekuensi Sederhana
Rendah 200 – 400 MHz 1.5 m – 2.0 m
Frekuensi Rendah < 200 MHz 2.0 m – 3.0 m
7
Sebelum pengesanan bermula, garis rentas yang bakal
dilalui oleh alat GPR perlulah ditandakan di bumi.
Kekerapan membuat garis rentas ini hendaklah selaras
dengan ketetapan jarak selang pengesanan yang
dihuraikan pada perenggan 3.1.2. Di samping itu garis
silang kepada garis rentas berkenaan perlu juga dibuat
untuk membolehkan pengesanan pepasangan utiliti yang
dipasang secara selari kepada arah garis rentas.
Kedudukan titik-titik mula dan akhir bagi setiap garis
rentas dan juga garis silang tersebut perlu diukur dengan
menggunakan peralatan ukur. Bagaimana pun sekiranya
alat GPR yang berintegrasi dengan GPS digunakan
maka prosedur ini tidak perlu lagi diikuti.
Peralatan-peralatan yang akan digunakan bagi menjalankan
kerja-kerja pengesanan geofizikal hendaklah terdiri daripada
peralatan generasi baru dan wajar mengandungi komponen dan
teknologi yang diperlukan untuk memberikan hasil terbaik.
3.1.2 Jarak Selang Pengesanan Setiap pepasangan utiliti bawah tanah perlu dikesan secara
berterusan setiap 20 meter di sepanjang jalan, dengan
tambahan kekerapan pengesanan (kurang daripada 20 meter)
dalam keadaan-keadaan berikut:
(a) apabila pepasangan utiliti bawah tanah itu bersambung
dengan bahagiannya yang terkeluar di permukaan bumi.
Dalam keadaan sebegini kedudukan bahagian yang
bersambung perlulah dikesan;
(b) pada lokasi terdapatnya perubahan arah pepasangan
utiliti; dan
8
(c) dalam keadaan tertentu apabila memerlukan jarak selang
yang lebih rapat, seperti di kawasan yang padat dengan
pelbagai jenis utiliti.
Kedudukan pepasangan utiliti yang dikesan dan ditandakan
pada permukaan bumi perlulah seterusnya ditentukan melalui
pengukuran.
3.1.3 Ukuran Kawalan
Ukuran kawalan dilaksanakan untuk memastikan orientasi dan
kedudukan pepasangan utiliti bawah tanah dan butiran topografi
yang diukur mematuhi kehendak ketepatan yang dinyatakan di
bawah. Ia boleh dijalankan serentak dengan aktiviti pengesanan
pepasangan utiliti bawah tanah dengan menggunakan peralatan
ukur konvensional, peralatan GPS atau dengan kombinasi
kedua-dua peralatan ini.
a) Ukuran Kawalan Menggunakan Peralatan Ukur
Konvensional
Pelaksanaan ukuran kawalan menggunakan peralatan
ukur konvensional yang melibatkan berbagai aspek
pengukuran termasuk penentuan datum ukur, cerapan
jarak dan sudut, dan penutupan terabas perlulah
dilaksanakan mengikut ketetapan yang terdapat dalam
Pekeliling KPUP Bil. 3/2003. Tikaian lurus yang
dibenarkan adalah tidak kurang daripada 1:8,000
manakala tikaian bearing yang dibenarkan adalah tidak
melebihi 10” setiap stesen dengan perbezaan terkumpul
maksimum 1’ 15” semasa menutup bearing.
9
b) Ukuran Kawalan Menggunakan Peralatan GPS
Ukuran kawalan menggunakan peralatan GPS perlulah
dilaksanakan dengan menggunakan jenis peralatan dan
kaedah pengukuran seperti yang ditetapkan dalam
Pekeliling KPUP Bil. 6/1999. Ketepatan relatif bagi semua
garis dasar selepas pelarasan jaringan hendaklah kurang
daripada 10 ppm.
3.1.4 Ukuran Pepasangan Utiliti dan Butiran Topografi Ukuran pepasangan utiliti dan butiran topografi boleh
dilaksanakan setelah tamatnya aktiviti-aktiviti pengesanan
pepasangan utiliti bawah tanah dan ukuran kawalan. Nilai-nilai
atribut bagi kedua-dua butiran tersebut juga direkodkan pada
peringkat ini.
Ukuran ini boleh dilaksanakan secara teknik bearing dan jarak
(ukuran terabas) dengan menggunakan peralatan ukur
konvensional, teknik penentududukan menggunakan peralatan
GPS atau pun penggabungan kedua-dua teknik ini dengan
syarat kedudukan mutlak setiap titik ukuran adalah tidak
melebihi 10 sm daripada kedudukan sebenar pada tahap
keyakinan 95% seperti yang ditetapkan di dalam Standard
Guideline.
Di dalam mendapatkan maklumat ketinggian, ukuran hendaklah
diikat kepada tanda-tanda aras yang berkedudukan baik,
sekiranya menggunakan kaedah ukur aras. Ukuran aras yang
dijalankan hendaklah sekurang-kurangnya memenuhi kehendak
ukur aras kelas kedua dengan tahap ketepatan yang tidak
melampaui 0.012√K meter, di mana “K” adalah jumlah jarak
laluan ukur aras dalam kilometer.
10
Peralatan ukur konvensional dan GPS yang digunakan bagi
maksud ukuran yang dinyatakan di atas perlulah mematuhi
spesifikasi ketepatan ukuran sudut dan jarak yang terdapat
dalam Pekeliling KPUP 3/2003. Peralatan GPS khususnya
perlulah daripada jenis dual frequency carrier phase receiver.
Pengukuran dengan menggunakan peralatan GPS hendaklah
mematuhi prosedur yang terdapat pada Pekeliling KPUP Bil.
6/1999 dan Pekeliling KPUP Bil. 9/2005.
Secara umumnya, ukuran pepasangan utiliti dan butiran
topografi melibatkan pengukuran terhadap:
(a) tanda lokasi pengesanan pepasangan utiliti bawah tanah
yang dibuat di atas permukaan bumi;
(b) tanda-tanda kedudukan setiap garis rentas dan lintang
bagi pengesanan menggunakan peralatan GPR (lihat
rajah 1);
(c) kedudukan pepasangan utiliti permukaan; dan
(d) kedudukan butiran topografi.
Butiran pepasangan utiliti serta butiran topografi yang perlu
dikesan dan diukur berserta dengan nilai-nilai atribut yang perlu
direkodkan adalah seperti di Lampiran A.
11
Rajah 1: Pengesanan menggunakan peralatan GPR
3.2 UKURAN PEPASANGAN UTILITI BAWAH TANAH YANG TERDEDAH (EXPOSED)
Ukuran jenis ini melibatkan pengukuran pepasangan utiliti bawah tanah
yang terdedah (exposed), iaitu dalam keadaan-keadaan berikut:
(a) ketika melakukan pengesahan terhadap kedudukan utiliti
melalui penggalian lubang ujian (test holes), dan
(b) ketika aktiviti pemasangan pepasangan utiliti (as-built)
dilakukan.
Garis rentas (laluan GPR). Titik-titik mula dan akhir di setiap garis wajar diukur.
Garis lintang (laluan GPR). Titik-titik mula dan akhir garis wajar diukur.
Arah pergerakan peralatan GPR ketika aktiviti pengesanan.
Kedudukan pepasangan utiliti bawah tanah.
12
Standard Guideline memperuntukkan kaedah penggalian lubang ujian
secara minimally intrusive untuk mendedahkan utiliti bawah tanah.
Penggalian lubang ujian boleh dijalankan dengan menggunakan
kaedah-kaedah berikut:
(a) Backhoe
Penggalian lubang ujian dengan menggunakan backhoe
merupakan teknik yang berisiko tinggi berbanding dengan
kaedah-kaedah lain. Ia sukar untuk dikendalikan serta tidak
begitu tepat dan dengan itu kaedah ini tidak digalakkan.
(b) Penggalian Menggunakan Alat Asas
Penggalian lubang ujian menggunakan peralatan paling asas
seperti penggali boleh juga dilakukan. Walaupun ia tidak
memerlukan perbelanjaan peralatan yang tinggi dan agak
selamat tetapi kaedah ini memakan masa dan memerlukan
tenaga kerja yang lebih.
(c) Ekskavasi Hampagas
Ekskavasi hampagas menggunakan sama ada tekanan udara
atau air untuk memecahkan tanah dan alat hampagas untuk
menyedut pecahan tanah tersebut. Saiz dan bentuk lubang ujian
akan bergantung kepada keadaan di lapangan dan boleh dalam
bentuk bulat atau empat segi, mengikut keperluan dan
kesesuaian. Sebagai contoh, ia boleh berdiameter 15 sm hingga
30 sm atau bersaiz sekitar 900 sm persegi. Kedalaman lubang
juga boleh berubah dari 0.5 meter ke 1.0 meter atau boleh
sehingga melebihi 3.0 meter, jika perlu sampai ke saluran
pembetungan yang dalam. Ini merupakan kaedah ekskavasi
lubang ujian yang disyorkan.
13
Urusan penggalian atau ekskavasi yang disebutkan di atas hendaklah
dijalankan secara berhati-hati supaya tidak merosakkan pepasangan
utiliti. Pengambusan dan penutupan semula lubang ujian juga
hendaklah diuruskan mengikut kehendak peraturan-peraturan pihak
berkuasa yang berkenaan. Di samping itu, kerja-kerja yang dijalankan
hendaklah dipastikan mematuhi kehendak perundangan yang
berkaitan dengan keselamatan pekerja.
Ukuran pengesahan kedudukan utiliti bawah tanah melalui
pendedahannya dengan menggunakan lubang ujian hendaklah
melibatkan:
(a) Ukuran kawalan seperti yang dijelaskan pada perenggan 3.1.3
di atas.
(b) Ukuran planimetrik dan vertikal ke atas pepasangan utiliti yang
terdedah.
Prosedur ukuran as-built pula melibatkan:
(a) Ukuran kawalan seperti yang dijelaskan pada perenggan 3.1.3.
(b) Ukuran butiran pepasangan utiliti di permukaan dan
pepasangan utiliti yang terdedah serta butiran topografi di
permukaan seperti yang dijelaskan pada perenggan 3.1.4.
4. KALIBRASI ALAT
4.1 Peralatan Pengesanan Peralatan pengesanan yang digunakan perlulah ditentukur mengikut
kaedah tentukur dan pada sela tempoh yang ditetapkan oleh pengeluar
alat. Sijil tentukur peralatan yang digunakan ketika pengesanan
perlulah dikemukakan bersama-sama dengan serahan lain yang di
jelaskan pada perenggan 6.
14
4.2 Peralatan Ukur Kesemua peralatan ukur yang digunakan bagi maksud ukuran
pepasangan utiliti perlulah di tentukur mengikut peraturan-peraturan
yang ditetapkan oleh JUPEM.
5. SISTEM RUJUKAN UKURAN
Nilai planimetri bagi setiap ukuran perlulah merujuk kepada sistem rujukan
Cassini-Soldner negeri ataupun Rectified Skew Orthomorphic (RSO) yang
berasaskan datum mendatar GDM2000. Dokumentasi bagi sistem mendatar
ukuran yang digunakan perlulah merangkumi maklumat jelas tentang datum
geodetik, elipsoid rujukan dan unjuran yang digunakan.
Nilai ketinggian bagi setiap butiran perlulah dinyatakan sama ada dalam
bentuk coordinate triplet (x, y dan z) ataupun sebagai atribut bagi butiran
tersebut. Nilai ketinggian ini perlulah diasaskan kepada Datum Tegak
Geodesi Semenanjung Malaysia atau datum tegak tempatan bagi kawasan di
luar Semenanjung Malaysia. Selain itu maklumat kedalaman secara relatif
kepada permukaan jalan yang sedia ada boleh juga dibekalkan sebagai
maklumat tambahan.
6. SERAHAN
Perkara-perkara berikut perlu diserahkan kepada pemilik utiliti / kontraktor
setelah selesai sesuatu projek pengesanan dan pengukuran:
(a) Data pengesanan dan pengukuran dalam format shapefile
menggunakan template-template yang dibekalkan oleh JUPEM yang
mematuhi piawaian MS 1759:2004 Geographic Information - Features
and Attributes Codes.
15
(b) Pelan pengesanan dan pelan / peta utiliti mengikut spesifikasi yang
ditetapkan dalam Standard Guideline dalam bentuk perin dan soft-
copy, bersekali dengan metadatanya. Pelan / peta tersebut perlulah
mengandungi pengesahan oleh juruukur tanah yang
bertanggungjawab ke atas kesahihan pengukuran.
(c) Sijil-sijil tentukur alat pengesanan.
Selain itu, bagi urusan rujukan di masa hadapan, rekod-rekod berikut juga
wajar dikemukakan:
(a) Rekod ukuran mentah GPS format RINEX dalam bentuk salinan
lembut.
(b) Rekod data logger / controller bagi ukuran GPS-RTK dalam bentuk
salinan lembut.
(c) Rekod ukuran konvensional dalam bentuk buku kerjaluar konvensional
atau elektronik.
(d) Rekod pengesahan sistem rujukan ukuran yang dinyatakan pada
perenggan 5.
7. PENUTUP
Garis panduan ukuran pepasangan utiliti ini mengguna pakai asas amalan
ukur semasa serta kaedah pengesanan pepasangan utiliti bawah tanah yang
lazimnya diamalkan di dalam industri utiliti. Ia sewajarnya diamalkan secara
sepenuhnya oleh pihak juruukur tanah ketika melaksanakan kerja ukur utiliti
bagi memastikan penghasilan data pemetaan utiliti yang konsisten dan
berkualiti tinggi.

GIS Data Rules and CAD Drawing Requirements.
1
GIS Data Rules
Geodatabase topologies help to ensure data integrity. Topology provides a
mechanism to perform integrity checks on our data and helps to validate and
maintain better feature representations in GIS geodatabase. Topology is
fundamentally used to ensure data quality of the spatial relationships and to aid
in data compilation.
1. Must Not Have Dangles
- Requires that a line feature must touch lines from the same feature class (or
subtype) at both endpoints. An endpoint that is not connected to another
line is called a dangle.
2. Endpoint Must Be Covered By
- Requires that the endpoints of pipeline features must be covered by point
features (e.g., scour, endcap, hydrant, etc.) in another feature class.
3. Must Not Self-Overlap
- Requires that pipeline features not overlap themselves. They can cross or
touch themselves but must not have coincident segments. This rule is useful
where segments might touch in a loop but where the same pipeline should
not follow the same course twice.
2
4. Must Not Mutliparts
- A multipart feature has several lines or polygons within it but references only
one set of attributes in the database.
5. Must Split between fittings/valves or other features
- A fitting/valve must connect two pipes, or a pipe intersection must be found
at the junction of two pipes.
6. Pipe Jump (pipe crossing)
- Smaller size over big size
7. Deliverable must use Air Selangor symbols and apply symbology rotation.
8. Data Structure and Attribute should follow our standard schema (Refer
