Replacement of Bridge Bearings and Expansion Joint - Harrow Manorway Abbey Wood Flyover Spans 1 to 5

Description

The contract is for the removal and replacement of an existing carriageway/footway expansion joint and 36 no existing bridge bearings at the A2041 Harrow Manorway Abbey Wood Flyover. 20 no bearings for Span 4/5 have been designed by the Client's consultant. The Contractor is required to design the remaining 16 no bearings for Spans 1 to 4. Extensive concrete repair works are required in conjunction with the installation of the new bearings. Extensive temporary works will be required to allow the removal and replacement of the bearings. A typical temporary works solution for the Span 4/5 works has been designed by the Client's consultant and approved by the Technical Approval Authority. The Contractor is required to design and gain approval for the permanent and temporary works required for the Spans 1 to 4 works.. Access to allow the carrying out of the works requires significant traffic management. Street works permits will be required on the A2041 Harrow Manorway and Felixstowe Road to allow the carrying out of the works. The permits will need to allow for short term full closures of the A2041 during jacking and de-jacking of the structure before and after replacement of the bearings and half width closures to allow replacement of the expansion joint. On Felixstowe Road it is anticipated that some carriageway incursion will be required and temporary traffic signals may be required at times to facilitate the undertaking of the concrete repairs and installation of the new bearings. Any necessary street works permits and traffic orders will be applied for by the Client in liaison with the successful tenderer.
