Grand River Dam Authority (GRDA) Bridge Inspection
CEC performs hundreds of routine bridge inspections annually. Some of the most notable recent inspections are those performed for the Grand River Dam Authority (GRDA) at Grand Lake, including the main bridge over Pensacola Dam. This bridge features unique concrete arch construction, is approximately 5,600 feet long, and is over 100 feet above the ground below. CEC has inspected the bridge with a snooper truck, and has more recently utilized UAV’s and remotely operated camera equipment to minimize the impact of inspection to traffic flow.
