Is the bridge site accessible for handling of prefabricated components and use of heavy lifting equipment?
In addition to access to the bridge site, access at the bridge site must be adequate to allow longer and heavier prefabricated systems to be moved into position, and equipment must have adequate capacity to erect the heavier components. The planning stage should include these considerations for optimization of prefabricated systems for rapid onsite installation, as done in downtown Chicago with self-propelled modular transporters used to move a bridge span into final position after it was constructed adjacent to its final position. • Are prefabricated foundations and substructures a possibility for this location? In many cases, foundation and substructure construction is the most costly and time-consuming part of constructing a bridge. To get maximum advantage from the on-site construction speed possible with prefabricated bridge installations, consideration should be given to using prefabricated components for foundations and substructures. Shallow foundations such as spread footings
