The Baltimore City Department of Public Works (DPW) is converting open-air drinking water lakes to buried tanks to help preserve the city’s drinking water system and comply with federal Safe Drinking Water Act regulations. Stiver Engineering provided a custom shoring pit with support frame, plans for pipe supports and pipe hangers for large diameter steel pipe. We also provided the review of pipe plugs and the design of thrust restraint steel frames for large diameter pipe plug testing. Stiver Engineering performed bi-monthly slope stability reviews for the tank executions which were 430 ft. diameter and 50 ft. deep. We also provided excavation plans in rock material at critical locations for the installation of the influent pipes and the tank foundations. We reviewed rock borings and provided a trench safety plan. DPW is investing in safer and more secure drinking water with underground tanks.

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.

The City of San Antonio, Texas is completing one of its largest flood control construction projects to date, a multimillion dollar effort to improve storm water drainage into Woodlawn Lake by replacing the existing channel with a new channel of greater capacity in order to remove numerous private properties and public infrastructure from the 100 year flood plain, which experienced catastrophic flooding in 2002.

The construction of Phase 2 of the Seeling Channel Improvements project includes completing the channel work from near Wilson Boulevard to Morning Glory Drive and features the demolition and replacement of 2,470 lineal feet of existing concrete channel and 2 concrete vehicular bridges which cross the channel at Huisache Avenue and Morning Glory Drive.  The excavation for the new cast in place concrete channel structure averages 60 feet wide by 15 feet deep and is supported by an engineered steel beam and wood lagging shoring system in order to accommodate the limited work area access between the channel and adjacent private properties.

In advance of the new concrete channel and bridge improvements, existing underground potable water and sewer lines were kept in service while the installation of new replacement underground utilities took place.  New underground utilities include 3,500 lineal feet of 8 inch to 16 inch water line, 2,500 lineal feet of 30 inch sewer line and 350 lineal feet of 24 inch to 60 inch storm drain line.

Stiver Engineering provided the contractor with construction consulting through the design of the steel beam and wood lagging shoring system that the channel walls were poured against.
