THIS AREA IS PREPARED SO THAT THE END OF THE
BRIDGE HAS A CONTACT LENGTH OF 33.5IN (0.85M)
MAXIMUM, MEASURED FROM THE END OF THE BRIDGE.
Site Marking for Bridge Build
1.2.9.1
After determining dimension `A' (see Table 1. 3), refer to Figure 1. 12 and mark out the
site using pegs and suitable tape.
1.2.10 Bridge Retrieval
1.2.10.1
Remove the home bank approach ramps.
1.2.10.2
Determine the bridge centerline and project it on to the site.
1.2.10.3
Refer to Table 1. 4 and mark out the site using pegs and suitable tape.
NOTE
Under certain extreme site conditions, it may not be possible to retrieve the bridge from the far
bank side and the same site that was used for building must be used for retrieval.
Unless the bridge is being retrieved from its known build site, always confirm the site
parameters for the proposed retrieval site.
1.2.10.4
When a preliminary study has not been undertaken for any reason, use the bridging crew
to carry out a reconnaissance of the proposed bridging site (including where possible the
far bank) before bridge deployment commences. Refer to Figure 1. 9 and determine the
longitudinal and transverse slopes of the bridge approaches.
