As part of the Brazos Street Bridge demolition in Houston, Texas, Stiver Engineering provided a demolition staging plan for the bridge concrete decking that would be replaced. We also developed a bridge beam shoring system and a plan to jack up the steel bridge beams to replace existing bearing pads at all bents and the abutments.
Stiver Engineering provided a design for three piers (Robert’s Point Park, Charlie’s Pasture, and Brundrett Memorial) in Port Aransas, Texas, using concrete reinforced with GFRP bars. The design consisted of the decking panels, beams, an abutment, and pier caps for the three piers. Stiver also provided a loading analysis for the support piles.
Houston’s Waco Street Bridge, which had frequently been hit by oversized trucks, was proposed for demolition by the Texas Department of Transportation. Stiver Engineering provided the custom plan that the contractor used to successfully complete the demolition.
As part of work on three new Highway 105 bridges that cross rivers between Brenham and Navasota, Texas, Stiver Engineering provided a sheet pile and tie rod shoring system design for the installation of the bridges’ bent foundation and abutment. The shoring plan included temporary wale sets, as well as a staging plan for accessing and excavating to the required depth to install the bent foundation and abutment. The final stage of work was a permanent sheet pile structure around the bent that was filled with low density concrete.
Stiver Engineering provided a variety of services for the Mason Park bridge project in Houston. We performed analysis and design for lifting sections, designed stiffener plates for lifting and the outrigger foundations for the bridge’s construction. The outrigger foundations were designed to handle the lifting of 70-ton steel pedestrian bridge section from the bayou banks. Stiver also created a soldier pile shoring design to provide access for the bridge tower foundation construction. We also designed the formwork plan and construction walkway decking design for the bridge tower pours.
