Stiver Engineering was asked to provide a crane lifting plan for lifting an expansion joint for the Fred Hartman Bridge located over the Houston Ship Channel. As the combined weight of the heavy-duty crane and the expansion joint exceeded the optimum load rating of the bridge, Stiver Engineering came up with a frame design that was placed under the crane outrigger pads to distribute the loads efficiently. Due to the limited work area Stiver Engineering proposed the lifting and installation of the expansion joint to be carried out in three stages.
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.
