Temporary Support and Traffic
Enquiry
Note 3 under scope of prestage 1 on Drawing sheet 143 and 179 indicates the entire bridge will be placed on temporary supports while bearings are being replaced. This would mean that temporary supports are required at all substructures for one time use only. Please confirm this statement is correct? If the statement above is correct then has the traffic staging accounted for temporary supports to be in place at all substructure locations? (open excavations to tops of all existing pier footings with support towers adjacent to live traffic).

Response
The Entire Bridge will be placed on temporary supports at all locations while bearings are being replaced, however, the contractor may propose an alternative sequence for review by the CA. The jacking loads and layout shall be updated by the contractor to reflect their proposed sequence. Open excavation is not feasible at all locations. Per OPSS 921.04.02.01 Section (h) the contractor is responsible for design and details for transfer of loads to substructure or founding strata as required. Temporary Off-Peak Lane or shoulder closures may be required to setup temporary works system. See upcoming Addendum 3.
