1. INTRODUCTION

Mandatory Requirements

1.1 Paragraphs of this Standard that are highlightedby being contained in a box are mandatory. Theremainder of the document contains advice andguidance.

General

1.2 This Standard describes certain records requiredfor highway structures on motorways and other trunkroads or in Northern Ireland all designated roads, butshould be read in conjunction with BD 53 (DMRB3.1.6) – Inspection and Records for Road Tunnels,when dealing with highway tunnels.

1.3 This Standard should be read in conjunction withSD 11 (MCHW 6.1.2) – Requirements for Health andSafety File, and the Construction (Design andManagement) Regulations (CDM) 1994: The Healthand Safety File. The records described in the Standardare considered by the Overseeing Organisations tosatisfy minimum compliance with the CDMRegulations with respect to structures records. TheOverseeing Organisation in Northern Ireland has optedout of SD 11 in favour of the CDM Approved Code ofPractice.

1.4 The records described by this Standard may notbe sufficient for effective management in allcircumstances. Where this is the case, supplementaryrecords should be compiled.

1.5 The Standard also identifies how the recordsshould be held and those parties responsible forcreating, maintaining, reviewing and updating records,i.e. the Designer, Contractor, Agent and OverseeingOrganisation.

1.6 This Standard supersedes BD 62/94 (DMRB3.2.1) – As Built, Operational and MaintenanceRecords for Highway Structures, which is herebywithdrawn.

February 2007

1.7 This Standard must be read in conjunctionwith BD 63 (DMRB 3.1.4) - Inspection ofHighway Structures, which provides details of therecords associated with inspections of highwaystructures.

Background

1.8 The records described in this Standard arespecifically identified to support the business needs andprocesses for managing highway structures, importantaspects of which include:

a. Providing information the OverseeingOrganisations are legally required to hold.

b. Providing information that supports themanagement of highway structures, e.g.inspection scheduling, maintenance planning,structural reviews and assessments.

c. Ensuring that records remain current andaccurate by adopting appropriate reviewing andupdating procedures.

d. Ensuring that records are held in the requiredformat, e.g. computerised Asset ManagementSystems.

e. Ensuring that records are created, maintained andmanaged by the relevant personnel/parties.

1.9 Details of the manner in which these records areto be held by respective Overseeing Organisations areprovided within the Annexes.

Definitions

1.10 The following definitions apply in this Standard:

• Agent – a party appointed by the OverseeingOrganisation to manage highway assets on theirbehalf, e.g. Maintaining Agent, Managing Agent,Managing Agent Contractor, Trunk Road Agent,Concessionaire, Service Provider or OperatingCompany. Where the Overseeing Organisationmanages the highway assets internally, the Agentwill be the branch or section to which the dutieshave been delegated.

Chapter 1Introduction

• Contractor – the organisation contracted by theOverseeing Organisation or Agent to undertakeconstruction works on its behalf.

• Designer – the organisation responsible for theoverall design including proprietary components.

• Structural Review – a review of an individualstructure or group of structures to establish orconfirm the validity of its latest assessment (or itsoriginal design, if there has been no subsequentassessment).

Implementation

1.11 This Standard must be used forthwith.Additional and specific requirements for the fourOverseeing Organisations in England, Scotland,Wales, and Northern Ireland are given in AnnexesA to D respectively of this Standard.

Quality Assurance and Audit

1.12 Agents must amend, if necessary, theirQuality Assurance system to reflect therequirements of this Standard.

1.13 The Overseeing Organisation reserves the right toaudit Agents against this Standard.

Chapter 3Managing Records

3. MANAGING RECORDS

General

3.1 This Standard describes certain records requiredfor highway structures and the associatedresponsibilities for providing, maintaining, reviewingand updating these records.

3.2 The details of some records are described inother documentation, e.g. BDs and respective UserManuals/Guides for computerised Asset ManagementSystems. Where this is the case, the descriptions of therecords are not duplicated in this Standard, instead theappropriate cross reference is provided. Wheredescriptions of records are not provided elsewhere thena description is provided in this Standard.

3.3 Records can be held in different formats, but aretypically held as electronic or hard copy (also,electronic records can be held in different formats).This Standard only specifies formats in the Annexes,and in some cases refers to supporting documentationthat specifies the required format. In this way, if therequired format of the record changes, e.g. from hardcopy to electronic or a change in electronic format, thenthis will be reflected in an amendment to the relevantAnnex or supporting documentation.

Computerised Asset Management Systems

3.4 The Overseeing Organisations have computerisedAsset Management Systems for highway structures.These systems hold records, assist the creation andmaintenance of records, and support managementprocesses, e.g. inspection and maintenance planning.

3.5 These systems have associated User Manuals andHelp Files, which are periodically updated to provideadditional guidance to users and/or to reflect changesand improvements to the system. This Standard doesnot replicate the guidance provided in User Manuals/Help Files; instead this Standard refers to thesedocuments where necessary.

3.6 Designers, Contractors, Agents and otherrelevant parties must use the Asset ManagementSystem, and associated User Manuals and HelpFiles, specified by the Overseeing Organisation.Details of the systems are provided in the Annexes.

February 2007

3.7 Where this Standard refers to User Manuals/Help Files these must be taken to be the latestversions.

3.8 The latest versions of User Manuals/Help Filescan be obtained from the Overseeing Organisation.Contact details are provided in the Annexes.

Roles and Responsibilities

3.9 This Standard supports the creation and ongoingmaintenance, review and updating of records. The rolesand responsibilities for these activities are described, ingeneral, in Table 2; the specific roles in eachOverseeing Organisation may be described in theAnnexes.

Chapter 3Managing Records

Other Records

3.11 The records defined in this Standard areconsidered by the Overseeing Organisations to beconsistent with CDM Health and Safety Filerequirements and good asset management practice.However, it is recognised that Designers and Agentsmay require additional records to support theiractivities. Exclusion of such records from this Standarddoes not preclude Designers/Agents from holding them,but the Overseeing Organisations do not accept anyfinancial or other responsibilities for these recordsunless formally agreed between the Designer/Agent andthe Overseeing Organisation.

Chapter 4Records for Highway Structures

Y STRUCTURES
4. RECORDS FOR HIGHWA
General

4.1 This section describes certain records requiredfor the whole life management of highway structures.The records are described under the following genericheadings which are considered to represent theminimum requirements of the CDM Health and SafetyFile:

a. Inventory.

b. Drawings.

c. Design.

d. Construction and demolition.

e. Materials, components and treatments.

f. Certification and tests.

g. Operation.

h. Inspection.

i. Maintenance.

j. Structural assessment and load management.

k. Legal.

l. Environmental.

m. Supplementary records.

4.2 These records should be stored as required by theOverseeing Organisation, as such they may be storedelectronically, in hard copy, or some combination of thetwo, and may be stored in one location, or a number ofdifferent locations. In whatever format or location therecords are stored they should be easily accessible tothose who require them and be clearly marked asbelonging to a particular structure. For example, thefirst point of interaction with these records may be aone page/screen that presents the key information aboutthe structure (e.g. reference, name, location, dimensionsand pictures) and includes references/links to the moredetailed records held under the above headings.

February 2007

4.3 Designers must provide the OverseeingOrganisation with records, in accordance with thisStandard, for all new structures. Forreconstructions, modifications and majormaintenance, Designers must provide theinformation required to update these records.

4.4 Agents must maintain and update theserecords, in accordance with this Standard, forexisting structures.

4.5 It is desirable that the records described in thisStandard are held for all existing structures. For someexisting structures there may be gaps between therecords described in this Standard and those currentlyheld. Agents should seek to identify these gaps andclose them in a cost effective and efficient manner bycombining record reviews, data collection and recordcreation with ongoing management activities. Forexample, these activities may be combined withGeneral Inspections, Principal Inspections and/orroutine maintenance activities.

4.6 Any significant costs associated with closingthe gaps in records or updating records for existinghighway structures must be agreed with theOverseeing Organisation.

4.7 Designers, Contractors, Agents and otherrelevant parties must check the relevantOverseeing Organisation Annex for any additional/specific requirements and for details of howrecords are provided to the OverseeingOrganisation.

4.8 During the life of a structure some records willbe superseded, for example, following maintenance orassessment. In all instances superseded records shouldbe retained in order to provide a full history for thestructure as this may be beneficial to futuremanagement. Any superseded files should be clearlymarked as such, including any reference to the file.

February 2007

Existing Structures

4.35 Inspection schedules and records must beprovided in accordance with BD 63 (DMRB 3.1.4)– Inspection of Highway Structures.

4.36 Condition information from previous inspectionsshould be retained as the change of condition over timegives an indication of the rate of deterioration and, insome cases, remaining service life. This informationcan be used to inform lifecycle maintenance planning.

Maintenance

4.37 Where appropriate, the aforementionedrecords (paragraphs 4.9 through 4.36) must bereviewed and updated following maintenancework.

Routine Maintenance Schedule

4.38 Routine maintenance comprises tasks, generallyundertaken on a 12 monthly basis, such as:

• removing graffiti;

• removing undesirable vegetation, e.g. that blocksdrainage, may cause structural damage orrestricts access;

• removing debris, bird droppings and otherdetritus that blocks drainage and promotescorrosion or other deterioration;

• clearing and ensuring correct operation of drainholes, drainage channels and drainage systems;

• repairing gap sealant to movement joints;

• checking operation of flap valves and greasingwhere required;

• checking and tightening where necessary anyloose nuts and bolts to expansion joints, parapetsupports and gantry holding down assemblies.Replacing nuts and bolts where appropriate;

• replacing expansion joint gaskets where this is aspecific requirement defined for the structure/component;

4/5



• removing general dirt and debris from bearings.Where appropriate, cleaning sliding and rollersurfaces if accessible and re-greasing. Followingany additional advice contained in the bearingmanufacturer’s instructions;

• ensuring free flow of water through culverts;

• ensuring correct operation of ancillary equipment(e.g. drainage pumps and associated sumps andpipework) and maintaining certification of liftingdevices;

• checking (and rectifying where necessary)seating of drainage gratings or covers, replacingany missing or defective items;

• checking, cleaning and replacing pedestriansecurity measures (e.g. mirrors, handrails, non-slip surfaces);

• checking for scour damage around trainingworks;

• checking holding down assemblies;

• repairing superficial defects in surface protectionsystems;

• ensuring special finishes are clean and perform tothe appropriate standards.

4.39 Whilst many of these tasks are fairly minor inthemselves, failure to carry them out may lead todeterioration of the structure and the need for morecostly repair operations in the future. The OverseeingOrganisations consider routine maintenance to be costeffective in whole life terms.

4.40 All structures, or groups of similar minorstructures, must have a routine maintenanceschedule consisting of cycle maintenanceactivities:

• New structures, reconstructions andmodifications – Designers must identifyand provide details of those items of routinemaintenance which are appropriate for newstructures, reconstructions andmodifications. The Agent must use thisinformation to prepare a schedule of routinemaintenance activities, prior to orimmediately following handover, which areappropriate for the structure/modification.

D

4c

4/6

This must include a review and, whereappropriate, update of the routinemaintenance schedule for the wholestructure in the case of modifications. Theschedule must be agreed with theOverseeing Organisation.

• Existing structures – if a routinemaintenance schedule does not exist for astructure, then the Agent must identify thoseitems of routine maintenance which areappropriate for the structure and prepare aschedule of activities. The schedule must beprepared during the next inspection. Theschedule must be agreed with theOverseeing Organisation.

4.41 Routine maintenance schedules must bemaintained by the Agent and updated, if necessary,in the light of new information and/or experiencegained from maintaining the structure.

esign Features Affecting Maintenance

4.42 During design, construction, re-constructionand modification (and their different phases),details of features which could have possibleimplications for future maintenance must beprovided.

4.43 Any special maintenance requirementswhich have been assumed in the conception,design and construction must be recordedincluding specific maintenance needs. Fullinformation on the actions required and thefrequency of these actions must be provided, e.g. aMethod Statement for maintenance work onstructural significant details with difficult access,life expectancy of components such as joints andbearings.

4.44 The Designer must provide details ondesign/construction issues and/or structurecharacteristics where these may influence futureassessment.

.45 These may include design live loading,onstruction sequence and construction joint positions.

February 2007



Ongoing Management of Existing structures

4.46 In general, maintenance records should be heldthat provide a full view of the maintenance cycle,including, but not restricted to:

a. List of maintenance needs – records shouldinclude details of the maintenance needs thathave been identified, e.g. action required,quantity of work, estimated cost of works, dateidentified and recommended action date. Recordsshould also indicate how the need was identifiede.g. inspection, assessment, lifecyclemaintenance plan.

b. Needs assessment – records should include thepriority/importance of doing the work. Recordsshould also describe how the needs are assessed,e.g. Risk and Value Management assessmentsand/or workshops.

c. Scheme/project development – records shouldprovide details of the schemes/projects that havebeen developed around the maintenance needs,e.g. combining maintenance needs to make betteruse of resources. Where relevant, this shouldinclude the AIP or equivalent documentation, seeparagraph 4.13. The records should provide aclear link between the maintenance needs and thesubsequent scheme/project.

d. Work tracking and completion – records shouldinclude details of progress (against agreedmilestones) and completion details, e.g.completion date, work acceptance and anyproblems encountered. Where appropriate,records should also be updated.

e. Lifecycle maintenance plan – where required bythe Overseeing Organisation an optimisedlifecycle maintenance plan, based on theexpected future (60 years) maintenance needs,should be provided for each structure. The planshould take account of how the structure behavesand deteriorates, the life expectancy of materials,treatments and components, the requiredcondition/performance, and optimised whole lifecosts. The assumptions and procedures used todevelop the plan should be recorded.

4.47 Maintenance records should be retained as thedetails on maintenance needs, intervention frequenciesand service lives can be used to inform maintenanceplanning.

February 2007

Structural Assessment and Load Management

4.48 Also refer to BD 21, BD 48, BD 60, BD 79 andBD 86 and other relevant guidance for information andrecords relating to structural assessment and loadmanagement. In general, these include the followinginformation, where appropriate, for each structure:

4.50 It is important that full account is taken ofenvironmental issues during the design, operation andmaintenance of highway structures. Relevantinformation should be held or cross referenced in thestructure records, for example, environmentalstatement, Environmental Impact Assessment (EIA) andSites of Special Scientific Interest (SSSI).

Supplementary Records

4.51 The records described by this Standard may notbe sufficient for effective management in allcircumstances. Where this is the case, supplementaryrecords should be compiled.

4.52 Agents must agree any additional costsassociated with supplementary records with theOverseeing Organisation prior to undertaking thework.

5. SUMMARY OF RECORDS

5.1 Table 3 summarises the records required forhighway structures, and distinguishes between thoserequired for new and existing structures. Theterminology used in Table 3 is:

a. Provide – original records that must be createdand provided.

b. Maintain – records that should be retained for thestructure and are likely to require regular/periodic reviewing, maintenance and updatingthroughout the structure’s life in order to reflectchanges. Superseded records should be retainedin order to provide a full history for the structurebut should be clearly marked as superseded.

c. Hold – records that should be retained for thestructure but are unlikely to require regular/periodic updating, but on occasion may requirereviewing and updating. Superseded recordsshould be retained in order to provide a fullhistory for the structure but should be clearlymarked as superseded.

d. N/A – not applicable.

5.2 Table 2 gives details of the parties that areresponsible for providing records for new structures andproviding and maintaining records for existingstructures.

Central Pier Base Excavation to founding level revealed some small fissures in the underlying sandstone.These were cleaned out, inspected and grouted up prior to construction of the baseslab. Further details are given in the report, sketch and correspondence following thesenotes.

Drainage Bearing shelf drainage at abutments and centre pier should be inspected and cleared asnecessary. The outlet pipes should be inspected and rodded. Gullies at base ofabutments should be inspected and cleared as necessary. The rear face drainage layeroutfalls by underground pipe to manholes. These outlets should be inspected to ensurethey are functioning correctly. Any significant accumulations of silt and debris on thebearing shelf or in the drainage system should be noted and investigated.

Waterproofing The bridge deck east service bay has a waterproof membrane of mastic asphalt. Thewest service bay invert is waterproofed with Conidec. Any defects in the decksurfacing should be investigated to assess possible damage to the waterproofing. Theservice bay cover slabs are covered by Bituthene and Bitushield. Deck waterproofingmust remain intact for the reinforcement in the deck slab to be protected as required.

Joints Sealants to expansion and movement joints should be checked for deterioration. Theepoxy mortar transition strips should be checked for debonding or cracking. Holdingdown bolts to cover plates should be checked for tightness.

Bearings Guides and dowels and rubber pot bearings should be inspected to ensure they arefunctioning correctly and to note any failure or excessive wear of moving elements.Metal sections of bearings, guides and dowels should be checked for corrosion andpainted as necessary. Rubber bearings should be inspected to ensure that the rubberprotection to the steel laminations has not cracked or debonded. The condition of thebearing seating material should also be checked. Holding-down bolts should bechecked for tightness and any welds checked for cracking.

Alkali-Aggregate During the construction contract period the Overseeing Organisation issued additionalReactivity substitute specification clauses to cover potential alkali-aggregate problems. The Test

House (give name) carried out an assessment of the aggregates and concrete withparticular reference to concrete mix details and cement contents. Calculations using thefigures given in the Test House (give name) report with information from cementprovided (give name) gave total alkali contents for the Class 45/20 concrete marginallyabove the 3.0 kg/m3 maximum recommended. Cement with a lower alkali content wasused for the parapet edge beams. For the other mixes calculations gave total alkalicontents less than 3.0 kg/m3. Further details are included in the appendix on Alkali-Aggregate Reactivity.

Services and service The services carried on the deck are indicated on the drawings. Particular attentionbays should be paid to the pipe bays to ensure they are properly drained and that services

are not leaking. It should be noted that the pipe bays are not designed to carry backfill.Vent pipes with flame traps lead from each service bay, to prevent pressure build up inthe event of a mains failure.
