INTRODUCTION

The Conservation and Buildings Section of the University Estates Directorate is responsible for the repair and maintenance of

the building fabric of University Buildings and supporting infrastructure for the whole of the University’s operational estate.

The purpose of this document is to provide guidance to Design Teams and Contractors on the specification and installation of

building fabric elements, for buildings which will be operated and maintained by the University Estates Directorate

The principles referred to in this document have been influenced by maintenance and operational requirements, the

resources available within the University Estates Directorate and also by the need to standardise building elements

throughout the 500,000m2 of building stock.

Building fabric choices should take into consideration value for money, here defined as ‘the optimum combination of whole

life cost and quality (or fitness for purpose to meet the users requirement)’ The design team must take into consideration the

choice of materials not only within the context of a project but through the life of a building. All parties in the supply chain

should provide reliable data on operational costs of products including maintenance.

Oxford University Estates Directorate is working towards implementing sustainable building practices on all its building

projects. Issues which the design team will be expected to address will include energy efficiency, specification of materials

for whole life value i.e. sourcing through to recycling.

New buildings should be designed to allow easy and safe access for cleaning and routine maintenance regimes including

window cleaning, roof maintenance and gutter and drain clearance.

Materials must be robust and comply with current legislation in supply and installation. All major fabric elements must have an

Agreement Certificate or equivalent. Bespoke building elements such as windows which are made using a non standard

system type which has not been tested will not be acceptable. Building elements which require annual, monthly or weekly

maintenance or inspection programmes from day one, such as inflatable roofs or oversized doors should be avoided. Such

materials will only be acceptable where given prior approval by the Head of Conservation and Building or where the

department agree to pay for the annual maintenance programme for a period of 10 years.

1.4 Maintenance Philosophy

1.4.1 It is a requirement that all buildings and their systems should be designed in such a way that they can be inspected,

maintained, repaired and extended with the minimum of disruption to the building users. The Designer must submit a

detailed Maintenance Philosophy to the UED, as early as possible in the design of the project, to demonstrate the

above objectives are being met. This document should also include information on sustainability of materials

products chosen.

1.4.2 The Philosophy should detail for example:

i) Building fabric elements to be used including walls, roof coverings, window types, sanitary installations, floor

finishes etc. Information on routine maintenance e.g. cleaning regimes for floors.

ii) Access information for maintenance regimes eg access plans for roof clearance and window cleaning

iii) Asset information including the expected life of building elements and equipment. Information on insurance

backed guarantees for particular products and data on operational costs for products over the life of the

building.

iv) The extent and effect on the building users of planned maintenance on the fabric and any plant elements e.g.

how roof replacement would be carried out where there is plant on the roof.

v) Information on future use and flexibility of the building e.g. provision for new plant and equipment

1.4.3 In the event of value engineering or requests for changes by the contractor during the course of a Design and Build

Contract these changes are to be discussed and agreed with the Head of Conservation and Buildings.

SECTION 2

CONSTRUCTION COMPONENTS AND FINISHES

2.1 Introduction

2.1.1 It is not the intention that this document should be prescriptive in its advice over the choice of building materials for

new University Buildings. The Design Team should however understand that the Estates Directorate are

responsible for the ongoing care and maintenance of all University buildings and that choices of materials should be

justified not just against the building project budget but against all future maintenance costs.

2.1.2 The following sections deal with the choice of building materials on an element by element basis. Observations and

guidance notes are based on current experience of maintenance of the existing building stock. These notes seek to

ensure that repeat problems are avoided

2.1.3 The University Estates Directorate is seeking to directly improve its supply chain management. We will be

undertaking a review of products with suppliers to take advantage of bulk purchasing opportunities and to improve

standardisation of products across the estate where possible. Information on this will be given to Design Teams

when this work has been carried out.

2.2 Legislative Issues

2.2.1 It remains the Design Teams responsibility to ensure that all building work complies with current legislation, and take

into consideration any imminent changes to legislation.

2.3 Contract Issues

2.3.1 It remains the Design Teams responsibility to ensure that the design and specification of materials is to current

standards and that they comply with the requirements of the terms of their appointment. No information given in this

document is to override this responsibility.

2.4 Roofs

2.4.1 Access to roofs.

i) Access to roofs should wherever possible be provided from within the building. The Estates Directorate wish to

discourage access to roof areas by ordinary members of staff. Accordingly all roof access doors are to have

UED suited locks.

ii) Any element requiring routine or periodic maintenance shall be easily and safely accessed. Edge protection

must be provided as necessary, where roof coverings are likely to be slippery, particularly in wet weather,

proper safe walkways must be provided. Access routes to external mechanical plant or roof top plant rooms

must be approved by the Head of Services at the UED.

iii) iii) Safe Access must be provided to all parts of the roof to allow for routine roof and gutter clearance. Ideally

edge protection or parapets are to be provided to all areas of the roof. Where latchway systems are to be used

as an alternative, the system is to be provided with a test and inspection certificate at handover, all fixings and

appropriate lanyards are to be provided as part of the project. All equipment is to be labelled and stored in a

of 8

locked storage box on site close to the roof access point together with a log book for test and inspection.

Harnesses for latchway systems are kept by the Direct Labour Organisation. The Design Team are to ensure

that any latchway systems are compatible with harnesses owned by the University.

2.4.2 Flat Roofs

i) Flat roofs should be designed for a minimum life expectancy of 30 years. Felt roof coverings would not

normally be considered acceptable.

ii) The most commonly used flat roof finish on University buildings is Sarnafil. This has proved to be a good

quality product when properly detailed and installed. Where left exposed this is a roof covering which is

extremely vulnerable to mechanical damage, and is not appropriate for roof areas where there will be regular

foot traffic. It is also extremely slippery in wet weather and properly designed walkways must be provided to

plant areas.

iii) Where flat roofs are specified, the siting of plant directly on the flat roof should be avoided. Plant should besited

in plant rooms. Where plant is sited on the roof, it should be seated on properly designed metal cradle systems

which elevate the plant above the surface and allow for future replacement or repair of the roof covering

without the removal of all plant. Such systems should be designed with future alterations or additions to plant in

mind.

2.4.3 Gutters and Downpipes

i) Where possible valley gutters between pitched roofs should be avoided. Where they do occur, they should be

adequately sized for maintenance access. They should also incorporate an emergency overflow pipe, with the

discharge sited in a position where it will not cause damage.

ii) Except for domestic scale projects UPVC gutters and downpipes are not acceptable

iii) External downpipes are preferred to internal downpipes. Any internal downpipe installations should allow for

easy and safe access for maintenance, should not incorporate any horizontal runs and should be detailed to

avoid condensation and excessive noise.

iv) Drainage should generally be based on a gravity system. Pumped systems will only be acceptable when

agreed with Head of Conservation and Buildings.

v) Particularly in areas where there will be vehicular movements, the bottom section of downpipe should be

strong enough to resist impact damage or be provided with appropriate protection

2.5 Windows

i) The use of non standard window types which have not been tested will not be permitted.

ii) Consideration should be given to durable window finishes to minimise on going maintenance costs

iii) UPVC windows are not acceptable.

of 9

iv) Careful consideration is to be given to window opening mechanisms. Ideally these should be secure, easy to

operate and should avoid clashing with likely desk/furniture positions.

v) The use of solar control films should be carefully specified to ensure that there is no adverse effect on the

glazing e.g. thermal stress. Internally applied film is preferred.

2.6 Internal Doors

i) Oversized doors should be avoided wherever possible. Such doors have an ongoing maintenance cost from

building handover due to the need for regular adjustments. Such doors also present considerable problems for

disabled users.

2.7 Flooring

ii) Unless Plant Rooms are on the lowest storey of a building they should be tanked and drained to prevent water

ingress to lower floors.

iii) Maintenance and cleaning regimes should be included in the O& M manual

2.8 Foul Drainage

i) Shall be gravity fed wherever possible. Pumped systems may be permitted only in exceptional circumstances.

Pumps should be installed in pairs to allow for servicing and with adequate failure warning provision.

ii) Any under floor soil or rainwater drainage to be in robust material e.g. heavy spun iron.

2.9 Cleaning

i) Consideration should be given to the provision of cleaners cupboards and facilities on each floor

ii) Materials should be chosen considering ease of cleaning and robustness.

2.10 Sanitary Fittings

i) Wherever possible shower facilities should be provided in every building

ii) Shower facilities adequate for use by persons with physical disabilities should also be provided.

2.11 Timber

i) All timber must be FSC certified. This includes timber for carcassing as well as finished timber for doors, etc.

SECTION 3

STANDARD OPERATING AND MAINTENANCE DOCUMENTATION

3.1 General

3.1.1 Comprehensive record drawings and operating and maintenance manuals must be provided as part of any project to

enable the UED to safely operate and maintain the building and service installations. Where the work is carried

out under the CDM Regulations, the manuals must be cross referenced to the project Health and Safety file. The

UED will not take responsibility for the operation of the building unless the necessary approved manuals

and drawings are available at the practical completion of the project.

i) Building Operating and Maintenance Manuals

Two hard copies and one electronic copy in cd-rom format of the O & M Manuals shall be provided which shall

comply with the latest UED Standard Specification for Operating and Maintenance Manuals for Building Fabric

ii) Record Drawings

As Built drawing completed in the correct format showing the general arrangement of all floors and a roof plan with

space numbers indicated in accordance with the University Standards must be issued to and accepted by the UED

Project Manager prior to Practical Completion

As Installed drawings completed in the correct format showing all above and below ground drainage systems,

annotated in accordance with University Standards must be issued to and approved by the UED Project Manager

prior to Practical Completion

SECTION 4

BUILDING LOG BOOKS

4.1 General

4.1.1 The Building Regulations Part L2 ‘Conservation of Fuel and Power in Buildings other than Dwellings’ requires the

provision of a Building Log Book for all new and refurbished buildings and for existing buildings where

significant changes have been made.

4.1.2 The Log Book shall be a summary document written in an easily understood style for building managers and non-

technical readers.

Typical Contents List of a Log Book

APPENDIX – Relevant certificates/tests

Style

All Log Books should be produced in the same style and format by using the templates provided in CIBSE publication ‘TM31

Building Log Books’.

The size of the Log Book will depend upon the size and complexity of the building, but should normally be between 20 – 50

pages long.

Two copies of the Log Book must be provided at handover of the building, a hard copy in a ring binder and an electronic copy

for future updating.

of 12

SECTION 5

5.1 HANDOVER PROCEDURE

5.1.2 The table below is an indication of typical items which require a signature to record that an action has taken place

before the project can be accepted as practically complete. The following checklists should be used throughout

the course of the project. This will keep the handover procedure simple and straightforward. The contents of the

table are intended as a guide only and should be amended to suit the particular project. The final version should be

agreed with the UED and should be included in the project tender specification in such a way that the Installation

Contractors are left in no doubt that the project will not be considered practically complete until the listed items are

completed and signed off by the appropriate person.

Appendix A

Disability Issues

Good practice guide, and accessibility checklist

Background information

An inclusive environment will be one, which is easily used by as many people as possible without undue effort, special

treatment, or separation. It should be aspire to offer people safe and independent access, and egress, as well as an unaided

means of movement around the building. There should be integrated participation with the use of facilities, and a recognition

that disabled people are all different and will have diverse needs that may be met in a variety of ways.

Legal framework

Building design is governed by Building Regulations, British Standards design of buildings code of practice, and duties under

the Disability Discrimination Act 1995. These regulations, codes, and Act provide the legal and regulatory framework for good

practice standards.

Approved Document for Part M of the buildings regulations.

These regulations set minimum standards in the areas covered of:

i. access and use

ii. access to extensions to buildings

iii. sanitary conveniences in extensions to buildings

British Standards S8300:2001 Design of buildings and their approaches to meet the needs of disabled people. This document

explains how a building should be designed to anticipate, and overcome the restrictions imposed by an inaccessible

environment.

Disability Discrimination Act 1995. The act outlines the duties required to improve access for disabled people in the areas of

employment, education, and services. Discrimination may occur when there is an unjustifiable failure to meet the duty to

make a reasonable adjustment.

Access plans

Access plans are a good way of providing information gathered from an audit. A long-term strategic view of how identified

access issues will be met through opportunities such as times of refit, or routine maintenance.

Management plans

Management plans provide information on how staff can aid access and egress. What procedures, and practices are in place

to help disabled users, what provision of equipment, and auxiliary aids (such as portable loop systems) are available, and

what the physical environment is like.

In order to undertake the assessment of access and egress it is essential to have knowledge of the building, and how it is

used. It is important to identify what the access and egress needs of staff, students, and public are.

of 19

Checklist

The following checklist can be used as a tool to ensure that the needs of disabled users are assessed within the context of

access and egress in general terms, and that integrated facilities are offered where practicable.

The checklist comprises of a number of sections covering different elements of a building. These broadly cover:

1. Approach to a building

2. Entering a building

3. Moving around the building, and access to facilities

4. Getting out of the building

1. Approach to building

Reasonable provision shall be made for people to gain access to and use the building and its facilities.

Accessible parking should be located as close as possible to main entrance. Bays should be clearly

marked, and sign posted. Dimensions for the parking bay should be 2400mm x 4800mm, with 1200mm

between each designated accessible bay.

Kerbs should be dropped.

Level access from designated accessible parking space to main entrance of building, and routes around,

and between buildings.

Routes should be clearly signed, with carefully located, and non-reflective logical way finding

information.

Surface material should be firm, slip resistant and distinguishable using textured and colour.

Ensure adequate lighting is in place (100 lux). Avoid pools of lighting.

External – approach to a building

Checked Comment

Accessible parking bays should be clearly

signposted.

Parking space should be identified as provision for

disabled drivers only.

Parking should be close to the accessible entrance.

Room for car doors to open fully.

Routes from parking space to accessible entrance

clear of obstacles, free of kerbs, and well lit.

Surface of parking space, and approach route to

building should be smooth, even, and free of loose

stones.

Approach routes should be clearly signed.

of 20

2. Entering a building


Approaches to external ramps should be clearly signed.

Ramps should be as shallow as possible. The maximum permissible gradient is 1:12, and should not

exceed 10m in distance or rise more than 500m. They should be at least 1500mm wide. The surface

should be slip-resistant. Handrails should be continuous to ramps and landings, provided on both sides

of the ramp, and should extend beyond the top and bottom of the ramp. The ramp area should be

adequately lit (100 lux).

External steps should be adequately lit. Handrails should be provided. The width of a flight of steps

should be at least 1200mm. Level landings free of door swings should be at the top, and bottom of flights

of steps. Surfaces should be slip-resistant. Nosing should be integral to the step, and be of a contrasting

material 55mm wide on both treads, and risers.

Handrails should not protrude more than 100mm. They should be easy to grip, and distinguishable from

the background.

Entrances to new buildings should be accessible. In existing buildings where it is not possible to make

the main entrance accessible, then an alternative accessible entrance should be provided.

Powered door opening, and closing systems are generally recommended in preference to non-powered,

manually operated doors.

An accessible entrance should be clearly signposted, and incorporate the international access symbol.

Door entry systems should be accessible to people with hearing impairment, and visual impairment.

Entry controls should be unobstructed. Turnstiles should be avoided.

The area immediately in front of the entrance should be level, and be at 1500mm x 1500mm in order to

accommodate a wheelchair. Thresholds should be flush.

Entering a building

Checked Comments

External ramps should be wide enough and of a

suitable gradient for use by a wheelchair user.

Handrails should be on both sides of the ramp, and

the surface should be slip-resistant.

Where a permanent ramp cannot be constructed, a

temporary, portable solution should be found.

External steps should have visual, and tactile

warnings at the top, and bottom. Nosing should be

easily identified.

Handrails should be provided, the area should be

adequately lit.

Entrances should be easy to find, and clearly

signposted.

Door openings should be wide enough for all users.

Have easy grip handles, and appropriate closer

mechanisms. Glass doors should be clearly marked

with manifestations.

There should be at least one accessible entrance

with level or ramped access allowing independent

of 21

access.

Where there are door controls these should be at an

appropriate height for standing, and seated users.

3a. Moving around the building, and access to facilities


Lobbies should allow sufficient room for a wheelchair user to manoeuvre without obstruction – a

minimum circulation width is 1200mm.

Appendix B

Asbestos Procedures

Asbestos

1. Introduction

This Policy has been revised to take account of the Control of Asbestos at Work Regulations 2002 (CAWR).

Under the CAWR, the University has duties to identify asbestos and set up an appropriate management action plan to control

the risk. The responsibility for managing asbestos (other than within laboratory equipment) rests with the corporate

University, not with departments.

Asbestos was commonly used in buildings until the 1980s and many University buildings will have asbestos in the building

fabric. It is commonly recognised as a hazardous material, but is a danger to health only when individual fibres are allowed to

become airborne and can be inhaled. This can happen when the material is being worked on (especially when broken, sawn,

drilled or sanded) or when it is in a poor state of repair.

2. Asbestos materials

The three principal types of asbestos are crocidolite (blue), amosite (brown) and chrysotile (white). All forms may produce

harmful effects if fibres are inhaled. Crocidolite is rare in University buildings; the others are commonly found within the fabric

of older buildings.

Because of their excellent heat resistance, chemical inertness and mechanical strength, asbestos products found wide

application in the building industry. For instance, within the University the material has been found as:

(a) thermal insulation - on pipes and boilers;

(b) insulation boards - for fire protection, as thermal and acoustic insulation on walls, ceilings and structural steelwork;

(c) sprayed coatings - for fire protection on structural steelwork;

(d) ropes and yarns - used as a sealing material or for filling gaps;

(e) asbestos cement - used in wall claddings, partitions, roofing, guttering.

These materials may also be found in old laboratory equipment, such as fume cupboards, ovens, furnaces and autoclaves. In

this case, care should be taken to ensure that such equipment is not re-sold, as this would constitute the supply of asbestos

containing products in breach of the Asbestos (Prohibition) Regulations 1992.

of 25

3. Work on asbestos

Work on asbestos is governed by the Asbestos (Licensing) Regulations 1983 and subsequent amending regulations; by the

Control of Asbestos at Work Regulations 2002 and the associated Approved Codes of Practice. Under these Regulations,

University personnel are not permitted to carry out work on asbestos insulation or coating, or on asbestos insulation board.

Such work may only be done by contractors licensed by the Health and Safety Executive (HSE) and all arrangements for

such work must be made through the University Estates Directorate.

University personnel are not permitted to work with any form of asbestos.

4. Marking of asbestos

Materials and laboratory equipment already identified as containing asbestos should be marked with the appropriate warning

signs, which are available from the University Safety Office. This is the responsibility of the department, except in areas under

the control of the University Estates Directorate, such as plant rooms and service ducts.

5. Records

The University Estates Directorate is responsible for maintaining a record of asbestos in the fabric of University buildings.

This record (the asbestos register) is the result of a non-destructive survey carried out by a licensed asbestos contractor and

subsequently updated. It is also amended whenever new finds of asbestos are made and therefore departments must notify

the Estates Directorate in such cases. Where there is doubt over the identification of asbestos, the University Safety Office

should be consulted.

The Estates Directorate's record does not include asbestos within laboratory equipment. Responsibility for this lies with

departments and they should ensure that they keep records showing the location of such equipment. Records should be

amended if materials are disposed of or relocated.

6. Disturbance of asbestos

Activities such as demolition and building alterations involving asbestos containing materials, if carried out without proper

precautions, are certain to cause uncontrolled release of airborne fibres.

Disturbance of asbestos during the course of work can usually be avoided by proper job planning, which includes as a first

step to have a thorough (known as a type 3) survey for the presence of asbestos. Materials already known to contain

asbestos should be apparent from their warning labels and from the Estates Directorate's asbestos register. More often,

asbestos is not known to be present, but its presence is foreseeable or may be suspected.

of 26

Therefore, whenever work is carried out which may conceivably involve the disturbance of materials which may contain

asbestos (e.g. work on wallboards, old fire doors or pipe insulation) then the person in charge of the project must first make

an assessment of the nature of the materials involved. The scale of this task depends on the size and complexity of the job. It

might involve checking for asbestos labels, checks on the Estates Directorate's asbestos register, checking for asbestos

hidden in ducts and behind panels, having samples taken of suspect materials, or having a survey carried out by a licensed

asbestos contractor or United Kingdom Accreditation Service (UKAS) accredited laboratory.

Where jobs are covered by University Policy Statement S6/00 (Construction (Design and Management) Regulations 1994),

this assessment must form part of the arrangements required for compliance and would therefore be included by the planning

supervisor in the pre-tender health and safety plan.

Asbestos is often difficult to identify without laboratory analysis; untrained persons taking samples may release unacceptable

numbers of fibres. Therefore if samples need to be taken, this must be done by a licensed asbestos contractor, UKAS

accredited laboratory or by a member of the University Safety Office.

Any damage to, or deterioration of, asbestos-containing materials should be reported to the appropriate building surveyor, or

in the case of asbestos contained in laboratory equipment, to the University Safety Office, so that steps can be taken to

assess the situation and repair the damage.

7. Removal or encapsulation of asbestos

Where asbestos is discovered in the fabric of a building, or where it needs to be disturbed in the course of a job, then a

decision on its removal or encapsulation will be taken by the University Estates Directorate in consultation with the University

Safety Office.

The University requires all such work to be dealt with under the procedure outlined in the appendix to this Policy Statement.

The responsibility for meeting the costs involved in the works is set out in Buildings Committee paper BC(87)5, i.e. where

asbestos in an unsafe state is discovered the costs of making safe (or removal) will be met by the University Safety Office.

Where scheduled work involving disturbing asbestos is carried out by the Estates Directorate, they will meet the cost. Where

work involving an area of asbestos is carried out at departmental request, the cost is met by the department.

8. Asbestos waste

Asbestos containing materials are defined as Special Waste and strict regulations cover their disposal. They must not be

disposed of in normal waste streams. An asbestos waste skip is sited in the Science Area, adjacent to the Estates

Directorate's Huts and small quantities of asbestos waste arising from departments must be disposed of here, after damping

and double-wrapping in heavy (minimum 400 gauge) polythene and sealing with tape. Care should be taken when placing

items in the skip in order to maintain the integrity of the wrapping: they should not be thrown in.

In the case of laboratory equipment, no attempt must be made to dismantle the item so as to dispose of the asbestos. The

item should be double wrapped and disposed of intact. If items are too large for the skip, departments should contact the

University Estates Directorate. The University Safety Office will make the necessary arrangements to empty the skip.

9. Use of asbestos by glassblowers

Glassblowers use paper and tape insulation, which has traditionally contained chrysotile. Substitutes are available and

previous University safety policies on asbestos have required departments to progressively replace all asbestos containing

materials. Departments still holding stocks of asbestos insulation should inform the Safety Office, who will make

arrangements for disposal.

of 27

Where asbestos insulation is still used by glassblowers, then the University Safety Office should be consulted for advice.

Regulations now require that substitutes are used wherever possible; or if substitution is not possible, then an assessment

must be carried out and regularly reviewed.

10. Asbestos fire blankets

Asbestos fire blankets are not issued to departments. Asbestos fire blankets are no longer kept in departments.

11. Departmental action

(a) Departments should note that University personnel are not permitted to work with asbestos insulation, asbestos

coatings or asbestos insulation board or any other form of asbestos. Work with asbestos will have to be carried out

by a licensed contractor.

(b) Departments should ensure that asbestos known to be in their buildings can be identified (the Estates Directorate

keeps an asbestos register, which can be consulted and the Safety Office's web site provides details of the asbestos

survey). The University has a duty to warn staff or contractors of the presence of asbestos, so that those intending

to work near it can take proper precautions to avoid accidental damage or disturbance.

(c) Planning for repairs, refurbishments and maintenance should include consideration of the possibility of disturbing

previously undiscovered asbestos during the course of the work.. In some cases, an asbestos survey will need to be

carried out as part of the planning process, especially where any demolition work is contemplated. Responsibility for

ensuring that planning and/or surveys are carried out may lie with individual departments or with the Estates

Directorate, depending on who is in control of the work.

(d) Departments should report any new discoveries of asbestos to their building surveyor, so the asbestos register can

be updated and any necessary action taken. Any damage to, or deterioration of, asbestos should also be reported

without delay so that remedial action can be taken.

(e) Departments should keep records of the location of laboratory equipment containing asbestos and amend them

following removal or disposal of the equipment.

(f) Laboratory equipment containing asbestos should be disposed of intact, either in the asbestos skip or by a licensed

contractor.

ARRANGEMENTS FOR REMOVAL OR ENCAPSULATION OF ASBESTOS

Prior to carrying out work on an existing building the design team will need to get an asbestos survey carried out

• As a starting point for any survey, the consultant should obtain the current register details kept at the Estates Directorate.

Issuing these details to the asbestos surveyor will prevent unnecessary repeat sampling and will provide useful

background prior to the survey.

• The asbestos surveyor must use the full University space numbering system. Departmental references can be added,

but these alone are not sufficient for recording in the register.

• If the survey is provided on disk, an additional hard copy is to be handed to the Estates Directorate’s Asbestos

Coordinator for updating the register. Also the Project Officer may require further copies, e.g. for the contractor’s site

use.

• Readable-size drawings are to be included with the survey. Large drawings must not be reduced in scale to fit an A4

format. They are to be clearly highlighted to show the extent of the survey within the building, and also marked with the

of 28

positions of the samples taken and with the exact areas of walls, ceilings, etc, to which the samples refer.

• The asbestos surveyor is to be instructed to immediately draw to the attention of the Safety Office any dangerous

situation which they find, rather than wait for the issue of the report. This can be done via the Project Officer or directly to

the Safety Office.

• At the end of a project, all documentation relating to removals, encapsulation, etc, are to be handed to the Space

Management Team at OUED, together with a completed action form which OUED will issue. Sketches are to be included

to show unambiguously which areas of asbestos have been removed.

If asbestos is identified, the Design Team are responsible for drawing up a specification for the works, which will include

information on the nature of the asbestos and the material to be treated or removed. They will obtain, if necessary, a

competitive tender from a contractor holding a current HSE licence.

The Design Team will give the selected contractor an official order containing the agreed asbestos clauses and send a copy

to the Safety Office. The order will include the arrangements for a pre-work site meeting of interested parties. These will

include representatives from the Design Team, Estates Directorate, the University Safety Office, the contractor, the

department concerned and representatives from the recognised trades unions. Where adjacent departments may be affected

by the works, then they should be invited to send a representative.

Reasonable notice of the meeting should be given. The Design Team and Estates Directorate will be responsible for inviting

all participants, except representatives of the trades unions, who will be invited to attend by the University Safety Office.

The following matters of detail should be discussed at the meeting, and notes taken:

1. The contractor must be aware of the Control of Asbestos at Work Regulations 2002, and the associated Approved Codes

of Practice. The University requires the work to be carried out in accordance with the Regulations and Approved Codes of

Practice.

2. The contractor must give details of his current HSE licence and indicate whether the work requires notification to HSE.

The notes should indicate whether he has provided (or will be providing) a copy of the HSE notification form ASB5.

3. Before work starts, the contractor must provide the person placing the contract with his written assessment and method

statement; a copy should be sent by the Estates Directorate to the University Safety Office.

4. The department will be asked to ensure that all its members in the vicinity of the works are advised of the following:

(a) the start time and duration of the job;

(b) precautions which must be taken to protect their health and safety;

(c) areas which will be out of bounds to them for the duration of the job;

(d) whom to contact to discuss any concerns about the job;

(e) arrangements for informing them when it is safe for the area to be reoccupied.

5. The University requires an assurance that the contractor will take reasonable steps to ensure that no University personnel

will enter any designated asbestos area or respirator zone (all such areas and zones must be properly demarcated and

signed in accordance with Schedule 2 of the Control of Asbestos at Work Regulations 2002).

6. The contractor must ensure that a copy of the latest test certificate for his exhaust ventilation equipment is present on site

for the duration of the works.

of 29

7. Any vacuum cleaners on site must meet British Standard BS5415: Part 2, Section 2.2, Supplement No 1, type H tested

with absolute filtration.

8. The material to be removed must be clearly identified and the contractor must have information on the nature of the

asbestos.

9. The meeting should consider other safety matters relevant to the work, e.g. isolation of electrical or piped services, or

identification of any high-risk activities nearby.

10. Arrangements for the contractor's access to the areas concerned must be agreed, as must the positioning of the

decontamination unit, power, water, drainage and electrical protection, where appropriate.

11. If negative pressure equipment is used, it must be left running continuously unless otherwise agreed with the University

Safety Office.

12. The integrity of any negative pressure enclosure in the work area must be tested, using a smoke test observed by a

person nominated by the University Safety Office (the contractor is expected to provide twenty-four hours' notice of the

proposed smoke test to the University Safety Office). Arrangements for preventing false triggering of the fire alarm system

during the smoke test should be agreed.

13.The contractor's employees must use protective clothing to the HSE approved standard (normally red overalls in the dirty

area, white in the clean area).

14. Waste must be doubly sealed in the work area, using red inner plastic bags and further sealed in plastic bags. The

arrangements for the transfer of waste from the work area should be agreed. Sealed bags of waste asbestos must be

stored in a locked container before being removed from the site by the contractor. Containers for asbestos should be

clearly labelled in accordance with the Control of Asbestos at Work Regulations 2002.

15.Following completion of the work, visual inspection and air monitoring is to be carried out (unless otherwise agreed with

the University Safety Office) by a UKAS accredited laboratory operating to criteria equivalent to those specified in EN

45001: clearance levels of less than 0.01 fibres per ml are required before any enclosure is removed. The laboratory's

report must be forwarded by the contractor to the University Estates Directorate, who will keep a copy for a minimum of

five years.

16. The meeting should identify someone who will check on behalf of the University that the work has been carried out in

accordance with the contract.

The meeting notes will be sent by the Design Team and Estates Directorate to all those attending the meeting and the

arrangements noted will be binding on the contractor and the department. The University Safety Office will forward copies to

the recognised trades unions.

There will be periodic auditing of this Policy by the University Safety Office

Space Numbering Protocol for University Buildings

There is a unique number for every room and space which identifies the building, the floor level and the room or space itself.

The number must therefore be written or quoted in full i.e. 304.20.05 Building 304, Level 20, Room 05

1. Building Number

Always 3 digits

2. Floor Level

Always 2 digits

Main floor levels start with 00 at the lowest (not necessarily the ground) floor and then 10, 20, 30, 40, 50, 60, 70, 80

and 90.

Mezzanine levels or half levels are 15, 25, 35 etc.

A building with a series of stepped levels could be 12, 14, 16 etc.

Allow for the numbering of major floor undercrofts.

3. Room Numbers

Always 2 digits with an optional suffix letter (A-Z) for revisions.

Numbers on each level start with 01, numbered clockwise starting from the front door/main stair.

Number every space defined by doors or parts of circulation spaces which are clearly separated.

Number: lobbies, large walk in ducts, lift wells, sheds, stairs and landings.

Position room numbers in the bottom left-hand corner of the room, about 800mm from the walls, avoiding obstructions on the

drawing.

List all room numbers, including those not used, in the revisions column of the drawing aligned to the top of the column.
