The San Juanico Bridge connects the islands of Leyte and Samar by linking the city of Tacloban to the town of Santa Rita, Samar. The road infrastructure is the second longest bridge spanning a body of seawater in the Philippines measuring 2,164 m (7,100 ft) in total length. It has 43 steel spans with the primary span measuring 192 m (630 ft). The bridge’s abutments are founded on steel H-piles while its piers are rock seated pedestals built using Prepakt method, having single cylindrical shafts and tapered cantilevered copings.

The bridge is part of the Pan-Philippine Highway (commonly known as the Maharlika Highway), a network of roads, bridges, and sea routes that connect the islands of Luzon, Samar, Leyte, and Mindanao in the country. The highway was proposed in 1965, and constructed under the administration of President Ferdinand E. Marcos to serve as the country’s backbone of transportation.

During the conduct of ocular inspection and tests on the bridge, it was found that scouring had developed on its foundations, thus, the recommendation was to conduct a detailed structural assessment of the bridge through the services of a qualified and competent experts, hence, this consulting services project.
