DEFINITIONS AND INTERPRETATIONS

The following terms used in this procedure have the specific meanings indicated:

Verified Utility Model utilities that have been surveyed in the field by a method to define its position and level. For example, a verified utilities model of a water pipe would result from the water pipe being located via ground penetrating radar or if the pipe had been uncovered and measured by survey instrumentation. Unverified Utility Model utility locations that have been derived from plans (as built) or digital data from the service provider but have not been measured too by Main Roads to confirm the service position. It is an indication that utilities are possibly in the general location.Main Roads - Main Roads Western Australia.Contractor - the party named in the contract to collect and present underground utility data.AHD - Australian Height Datum.3D Three Dimensional.

UNDERGROUND UTILITY DATA

The minimum requirements for a underground utility survey within a designated Main Roads project area are:

Collected utilities must comply with a nominated utility quality standard (A, B, C or D)

All original plans and digital files collected from the utility providers in their original format must be supplied to Main Roads.

All utility data must be converted to the requested local Main Roads project zone. The utility information shall be converted to digital MX data files with Main Roads string and point codes being utilised.

A utilities survey report must be supplied containing metadata statements for each type of utility supplied from each utility provider.

A utilities plot shall be supplied on request from the Main Roads project manager. The original brief will instruct the consultant if a utilities plot is required before commencing the work.

All data and reports generated from the use of this standard must be lodged with the Data Manager within the Road and Traffic Engineering Branch of Main Roads.

Coordinate System

All utilities data must be supplied in the local Main Roads approved project zone. The nominated local project zone will be provided by the Main Roads contract manager. Parameters for local main Roads project zones can be requested from the Senior Geodetic Surveyor or found on line within the Main Roads Survey Portal.

All utilities data must be 3D and relate to the Australian Height Datum (AHD). If the utility provider supplies 2D data, then the data must be converted to 3D and have -999 nominated as the height component.

Entry onto Land

It is the consultants responsibility to seek and obtain permission from landowners, occupiers or management authorities before entering any property to undertake survey work. Property includes Crown land which may consist of Reserves, National Parks or State Forests. Work may include, but is not limited to, traversing, investigation, surveying and uncovering utilities.

The consultant shall maintain a written report of all contacts. Details about each contact are to be outlined in the Underground Utilities Survey report.

Any queries made by land owners with respect to the project are to be referred to the Main Roads Project Manager.

If access onto land is refused by the owners the contractor will be required to immediately contact the Main Roads Project Manager to discuss the need for entry onto the land. If entry is required for the completion of the contract and there are no other alternatives, then Main Roads will arrange formal notification using delegated powers under the Land Administration Act. A formal notice of entry requires Main Roads to provide 7 days notice to the owners. The process to arrange the formal notice of entry may take some time and the consultant must liaise with the Project Manager to ensure disruption to the contract schedule is minimised.

Environmental Impact

All work is to be performed such that environmental impact is minimised. Any breach of environmental and heritage legislation during the execution of works is the sole responsibility of the consultant. The consultant shall ensure any disturbances are kept to an absolute minimum. The consultant shall reinstate, clean-up and leave the site as close to its pre-disturbed condition as possible on completion of any work or investigation.

New tracks shall not be formed, existing tracks altered, fencing cut, clearing carried out, or damage or disturbance made of any kind unless approved by the Main Roads Project Manager.

The consultant shall be responsible for the cost of reinstating any damage to property resulting from their work.

original UTILITY SEARCH DATA.

All original utilities search data provided from the utility provider must be supplied to Main Roads in addition to the final utilities data that has been altered to comply with Main Roads coordinate system, string codes and file format.

All hardcopy plans and digital files in the original data format and coordinate system must be provided to Main Roads.

UNCOVERING UTILITIES

Any utilities uncovered must be by a recognised licensed body that is qualified to uncover buried utilities (i.e. pot holing or vacuum dredge). The integrity of the service and the safety of the workers and public must be maintained at all times.

ENTERING MANHOLES

Man holes and underground areas are not to be entered.

UTILITY Quality CLASS

An underground utilities survey will be requested by the Main Roads project manager to one of the following quality classes to allow data to be customised to Main Roads requirements.

Quality Class A

Quality Class A is the highest accuracy order for a utilities survey. The consultant will be required to perform the following tasks to complete a quality class A utilities survey.

The consultant must perform a quality class D (see 12.4) or higher survey to search and identify all utilities in critical areas that have an impact on the scope of works. Liaise with the Main Roads contract manager to determine the most efficient way of exposing and locating the utilities. Expose / pot hole the utility and measure directly to it by total station, theodolite or GPS. Achieve accuracies of -/+30mm horizontally and vertically. The consultant must be licensed to expose the requested utilities or use a subcontractor who is. All necessary approvals must be in place to undertake the work. The consultant must ensure the integrity of the service and the safety of the workers and public are maintained at all times. Present the utilities survey in Genio format adopting MRWA codes and file format. Provide a utilities survey report.

The outcome of this survey is a verified utilities model.

Quality Class B

The consultant will be required to perform the following tasks to complete a quality Class B utilities survey.

The consultant must perform all tasks for a quality class D utilities search (see 12.4). All utilities shall be surveyed by an indirect survey method. This can involve locating gas, electric, phone, water, sewer and cables with methods such as ground penetrating radar or active and passive frequency detectors, electromagnetic detectors, acoustic detection systems. The accuracy of the utilities shall be located to -/+ 100 mm at a depth less than 1.2 meters and an accuracy of -/+200 mm for depths greater than 1.2 meters. Leave markings on the earths surface to denote the position of the service underground. Present the indirect utilities survey in Genio format adopting MRWA codes and file format. Provide a utilities survey report.

The outcome of this survey is a verified utilities model.

Quality Class C

The consultant will be required to perform the following tasks to conform to quality Class C.

Performed all tasks for a quality class D utilities search (see 12.4). Survey all surface utilities in accordance with the relevant Main Roads survey standard. Depending on the survey capture technique, either 67-08-43 Digital Ground Survey standard or 67-08-44 Mapping standard is to apply. Alter all subsurface utilities locations obtained from supplied plans to align with surveyed surface features to depict their location. These lines are to be clearly noted in the utilities report or on plots as probable location only. Liaise with the Main Roads project manager for requirements. Consultant may be required to lift service manhole lids to confirm pipe directions and measure pipe diameters. Sub surface man holes and areas are not to be entered for safety reasons. All observations and measurement are to be performed from outside the manhole. Supply all utility information in digital format adopting Main Roads codes and file formats. Provide a utilities survey report.

The outcome of this utilities survey is an unverified utilities model.

Quality Class D

The consultant will be required to perform the following tasks to complete a quality Class D utilities search.

The consultant is required to go to site to conduct a visual site survey of the requested area to identify any utilities in the area. The consultant shall perform a utilities search at the dial before you dig service. (Ph 1100 or web site http://www.dialbeforeyoudig.com.au.) Collect utilities data from custodians not covered by the dial before you dig site. This can include property owners, mine sites, local authorities etc that have been identified in the site visit. Supply all utility information in digital format adopting Main Roads codes and file formats. Supplying all raw data obtained from the service providers. Provide a utilities report.

The outcome of this utilities survey is an unverified utilities model.

data format.

All utilities are to be searched, converted and supplied as MX data files. Scaling of hard copy utility provider plans may only be performed when no electronic version exists with the utility provider.

Only Main Roads feature codes detailed at Appendix A can be used. Any additional codes required must be obtained from the Data Manager, Road and Traffic Engineering Branch, Main Roads. All additional approved codes must be clearly noted within the utilities survey report. Existing Main Roads codes must be used with text clearly denoting differences in details.

All utilities must be 3D. All original utilities without levels must be made 3D and given a null level of 999.000.

String Compression on MX data files.

All utility strings supplied in MX Genio files must be run through compression software to ensure that the number of Main Roads captured labels do not exceed the permutation of possible labels available.

Acknowledgement must be written within the utilities report that the MX Genio files supplied to Main Roads have been compressed.

Compression software can be obtained from the Data Manager, Road and Traffic Engineering Branch and Technical Services Branch, Main Roads.

Utilities Extent Data File

An outline of the utilities investigation area must be supplied in a single file and labelled as a two-dimensional B string. The string must form a closed polygon.

MX Utilities Data File naming convention.

All utilities data must be provided to Main Roads in MX format files.

Digital files shall be named in accordance with Main Roads Document 67-08-87 Data Model and String Naming Guideline and consist of two files. These are the utilities data (util) and the boundary of the search area (ext).

For example, if the Great Northern Highway had utilities collected within the road reserve corridor from SLK 25 55 then two data files would be supplied and labelled accordingly:

All utilities data would be supplied within

H6_25_55_util.gen.

Where:

H6 is the Main Roads code for the Great Northern Highway25 is the start SLK55 is the end SLK andutil is the annotation to denote a utilities file

Additionally a second file would outline the extent of the service survey and would be labelled

H6_25_55_ext.gen.

Where:

H6 is the Main Roads code for the Great Northern Highway25 is the start SLK55 is the end SLK andext is the annotation to denote that this file outlines the extent of the area that the service search was performed on.

Road numbers and SLKs for each project will be supplied by the project manager.

utilities plots.

If a plot of the utilities data is requested from the consultant then the following must apply:

The plot shall be supplied in hardcopy and as a digital tif or ecw file.

All service plots must be supplied on an A1 sized page. Scales shall be 1:500 or 1:1000 but can be altered on request.

The digital utilities models plot layout shall be presented in accordance with the following information. Please see Appendix C for layout requirements.
