the developer requiring the basis of the design to be defined. The TAS lists all the current standards and documents relevant to the design of Highway Structures. Clause 4.2 of the AIP refers to the TAS, and any documents which are not intended to be used are to be struck through, and the TAS attached to the AIP to complete it. The signed AIP with attached TAS is to be submitted by the Developer or his Consultant to the TAA, in duplicate*. When approved by the TAA the AIP with attached TAS will be endorsed by the Bridge Manager or his appointed delegate on behalf of the TAA and one copy returned to the Developer/Consultant. The AIP must be endorsed before the design may begin. STRUCTURE DESIGN Following the receipt of the endorsed AIP document the design of the structure may commence. On completion of the design the structure details shall be submitted to the independent checker identified in the AIP. DESIGN CERTIFICATE Following the design check the Developer’s Consultant is to complete and issue a Design Certificate certifying that the structure has been designed in accordance with the AIP. Two signed copies* of the certificate must be submitted to the TAA for endorsement. Two copies of all the construction drawings and reinforcement schedules listed on the certificate are to be enclosed with the Design Certificates for approval. One copy of the Certificate will be returned to the Consultant upon endorsement. CHECK CERTIFICATE All structures must be checked by an independent checker approved by the TAA. Upon completion of the check the checker shall issue a Check Certificate. Two signed copies* of the Certificate are to be submitted to the TAA for endorsement. One endorsed copy of the certificate will then be returned to the Consultant. MAINTENANCE AUDIT Once the signed copies of the design and check certificates have been submitted, a Maintenance Audit is carried out by the TAA. This is to ensure that aspects affecting the on going inspection and maintenance of the structure are to the TAA’s approval. If the procedures in this section have not been followed and endorsed by the TAA, construction WILL NOT be permitted, nor will approval for adoption be given in cases where the road is proposed to be adopted. 1.1.5.5 TECHNICAL APPROVAL OF CONSTRUCTION The construction work may not commence until any legal agreements are signed, if appropriate, the Consultant is in receipt of the Design and Check Certificates endorsed by the TAA and the Developer’s site supervision arrangements are agreed by the TAA. The Developer must notify the TAA of the programmed start and completion dates, prior to any works commencing on site. Supervision of the works shall be the responsibility of the Developer but must be carried out by a competent consultant approved by the TAA. In addition the TAA is to be permitted access to the works at any time during construction for audit supervision checking. This will be undertaken at intervals dependent upon construction and will include important aspects of the construction work. The TAA shall be advised in advance and be regularly updated of key operations and their dates in the construction programme. The full cost of the audit supervision and associated reporting is to be met by the Developer. Compliance, certifying that the structure has been built in accordance with the approved drawings and specification is to be prepared by the Supervising Consultant. Two signed copies* must be submitted to the TAA for endorsement. Included with this must be the As-Constructed Records comprising the As-Built Records (as specified by the TAA), Maintenance Manual and the Health & Safety File (in accordance with the Construction (Design and Management) Regulations 1994. The As-built drawings are to be negatives, not paper prints. One copy of the Certificate of Construction Compliance will be returned to the Supervising Consultant upon endorsement. Approval for adoption WILL NOT be given by the TAA until the Certificate of Construction Compliance and the As-Constructed records have been received and approved by the TAA. *Documents may be photocopied to produce duplicates, but both copies must be signed in ink or biro. 1.2 ADOPTION 1.2.1 PROCESS Developers and Authorities involved in the process of adoption should take a holistic approach to the process to ensure ALL spaces in the public realm are maintained for the lifetime of the development. If not all the spaces can be formally adopted then alternative arrangements must be put in place for the spaces to be maintained for the lifetime of the development, or they should be designed out. In order to determine how all the areas are to be maintained, every space within the public realm should be given a defined primary function. Once the primary function for each of the spaces has been defined, then steps can be taken to decide how the space is to be maintained for the lifetime of the development through adoption or alternative arrangements. This outlined policy approach will be underpinned by detailed adoption criteria for both open space and highway elements of a proposal. Alternative provision for maintenance for the lifetime of the development may take many forms ranging from the setting up of management companies to dedicating land to Parish Councils. Commuted sums are likely to be required for the long term maintenance of open space, landscape/amenity areas including verges and all structures including public art. These will be dependant on the specific adoption criteria of each authority. The flowchart demonstrates a process which if followed, would ensure all spaces have a function and that no spaces are left without a maintenance provision put in place. The nature of the flowchart encourages a development team approach to the issue of adoption and long term maintenance. Specific open space adoption criteria are to be defined by individual local authorities but general principles might include: safety considerations; standard of work; ease of maintenance. process AS-BUILT REQUIREMENTS Upon completion of the works a Certificate of Construction A G U I D E T O S U S T A I N A B L E D E V E L O P M E N T Kent Design 13
