Other advantages of precast bent caps include reduction in environmental impact due to decreased on-site construction time and removal of environmentally hazardous operations to less intrusive locations; increased quality as bent caps are fabricated in a more controlled environment; improved safety for construction workers and the traveling public due to reduced exposure to hazardous conditions; and improved overall economy (6)
