The city of Brier owned and maintained a wooden pedestrian bridge that was built in the early 1980s and crossed Scriber Creek as part of a neighborhood trail. This bridge, supporting a gravity sewer crossing, was in a severe state of failure. PACE led a multidisciplinary team of engineers to replace the existing bridge with a new prefabricated pedestrian bridge spanning 88 feet across Scriber Creek. The bridge is a weathered steel structure, with handrails, a concrete walkway, and pipe supports for the suspended sewer pipe line. The new pile-supported abutments were located out of the waterway to improve stream hydraulics. The old bridge supported the live sewer line until the new bridge construction was complete. The project included bank stabilization to divert the stream channel away from the existing stream bank and bridge abutments. The solution of using a prefabricated bridge saved the city over $250,000 and allowed completion of the work within the short window of the hydraulic permit. PACE provided topographic surveying, permitting support, and construction management and inspection services. This project required coordination with the Washington Department of Fish and Wildlife, the U.S. Army Corps of Engineers, and the Department of Ecology.
