Stiver Engineering provided critical design services and analyses for a process water treatment facility at HEB’s warehouse complex on Space Center Drive in San Antonio, Texas. Our work encompassed pipe support designs and analysis, CMU block wall designs, and foundation designs for the operations building and the canopy structure. The pipe support designs included thermal, gravity, seismic and thrust analysis for the process piping, overhead pipe support structures, and a 43.5-foot-tall pipe support tower between process tanks. Multiple CMU block walls were designed for the operations building. Foundation designs were for the operations building, canopy structure, slabs for rolling dumpsters and a foundation design for the pipe supports.

As part of a major infrastructure project at the Schoharie Reservoir in Gilboa, New York, Stiver Engineering provided a variety of services for a low-level outlet designed to release water downstream into Schoharie Creek to facilitate dam maintenance and emergency response, mitigate flood risk, and enhance downstream habitat for fish and wildlife. The work includes construction of a 9.5-foot diameter micro-tunnel at a depth of 160 feet. Stiver provided designs for the gate shaft as well as analysis of the steel jacking frame for the tunnel machine and steel pipe. We also provided trench safety designs, thrust block designs, steel pipe casing designs, anchor bolt attachment designs, and a structural review of the Herrenknecht tunnel launch seal and pipe break frames, among other services.

Stiver Engineering provided a wide array of land development services for a contractor’s headquarters and operations yard on Luthe Road in Houston, Texas. Our work included plans for drainage, grading, landscaping, paving, stormwater pollution prevention, traffic control, and aggregate storage. We also created designs for a truck washout, drilled shaft foundations for concrete batch plant storage tanks and a steel canopy building structure, a hopper ramp with spread footings and a hopper slab foundation with drilled shafts.

Stiver Engineering responded to an emergency situation regarding a sinkhole beneath the control building at the Houston Water Control and Improvement District’s No. 47 wastewater treatment plant. The sinkhole, which was roughly 20 feet wide and 30 feet deep, was jeopardizing the building’s stability as well as the plant’s effluent line. Stiver proposed a solution to save the control building and keep the plant operational during construction. We developed and delivered a design and provided support to the material supplier and the contractor until project completion.

The 341st Training Squadron, located in San Antonio, Texas, provides trained military working dogs and handlers for the Department of Defense, as well as other government agencies and allies. The squadron aims to be a world leader in procurement, training, veterinary care and distribution of military working dogs and their handlers. As part of that goal, the squadron commissioned the construction of new housing structures to provide world-class facilities for the animals.

Stiver Engineering provided structural engineering services for the design of the foundations, structural steel and precast kennels for the nine war dog housing buildings.
