Reason for using cast-in-place vs. precast?
A cast-in-place Exodermic™ design eliminates cold joints. On smaller projects, cast-in-place projects will generally be less expensive because no precast form work has to be fabricated (for the edges of the panels and for the blockouts over stringers). This generally reverses on larger projects, particularly ones where the bridge is located in a high labor cost area. Since the grid portion of an Exodermic™ deck takes the place of form work in the field, cast-in-place construction is fairly fast, though not as fast as with precast Exodermic™ panels, of course, where the work can be done overnight if needed.
