Overview
The Timmons Group structural team managed repairs for two bridge structures located at the Pentagon. The main bridge is a three-span concrete structure with arched beams currently spans the Pentagon Police staging area and other support services. It has an overall length of 280 feet and a width of 200 feet.
The second bridge is Corridor 9 over the same area. This vehicular bridge services the secured areas of the Pentagon and is 280 feet long with a width of 35 feet. As a newer structure, the repairs on this bridge are limited to surface concrete repairs.
Working with security clearances, our team of structural engineers assessed the repair needs for the structures and proposed repair details. We worked with the government and the contractor to streamline the repair process.
Construction of the repairs was complicated by the need to maintain use of a section of the area below the bridges at all times. To meet this requirement, the construction sequence was broken into three distinct sections which aligned with the three spans of the structures. Repair quantities were watched closely to ensure that the project goals could be met for the entire project.
