Site Marking for Bridge Build
site using pegs and suitable tape.
Remove the home bank approach ramps.
Determine the bridge centerline and project it on to the site.
Refer to Table 1. 4 and mark out the site using pegs and suitable tape.
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.
When a preliminary study has not been undertaken for any reason, use the bridging crew

longitudinal and transverse slopes of the bridge approaches.
