Compliance of Technical Assurance Requirements for MEP Installations at Crossrail Stations, Shafts and Portals
Summary
This paper highlights the approach adopted by Crossrail to demonstrate compliance with technical assurance requirements for MEP installations at stations, shafts and portals. The common approach has taken into consideration the diverse nature of design and complexity of installation at different work sites. The documentation system used was supported by digital information management system (eB) in Crossrail to provide efficient retrieval of information and audit trail.
The technical assurance documentation suite consists of lead assurance documents, compliance certificates and supporting quality documents (backing evidence). They should be complete, adequate and suitable for the purposes of enabling Crossrail to obtain authorisation to enter into passenger service.
Key success factors for an effective technical assurance are:
A good mix between procedural and technical compliance evidence
A good grasp of the pertinent assurance requirements in particular statutory requirements and industry codes
A structured line wide documentation system
Coherent acceptance criteria line wide.
