Highway 78, Brawley Bypass utilized BIM during all phases of construction. It was used to check early quantities and design logistics. This helped in staging, balancing materials and constructing the state appointed temporary construction easements. The final BIM model was used to check intersections, vertical curves and grade breaks in the office before it went to the field. Loaded on the motor graders, it was used in prepping the road bed's foundation treatments and roadway structural sections and finishing grading of the sub-base surfaces. CAT D9 dozers with machine guidance were used to build and complete fill-slope work and embankments, and field personnel used handheld GPS (Rover) to check quantities and set and check grades all loaded with the BIM model.
