Geotechnical
Engineering
Soil, rock, and groundwater conditions at every site are different. We assess the specific site conditions and design earth structures (slopes, channels, and dikes), foundations (retaining walls, bridges, buildings, tanks), and subsurface structures (clarifiers, lift stations, buried utilities, tunnels) to economically achieve the specific project objectives.

Construction Materials
Engineering
& Testing
Construction material performance is key to the function and durability of any project. We engineer and test materials such as soil, concrete, and asphalt so you get what you pay for and the project performs as expected.

Environmental Geology
& Engineering
Impact from hazardous waste, wetlands, faulting, and/or NEPA processes are serious concerns for project development. We identify such concerns early in project development, and provide strategies to mitigate impacts and provide the proper regulatory approval so the project can proceed on time and achieve the project goals.

As part of North Texas Municipal Water District’s commitment to meeting steadily increasing regional water needs, Bois d’Arc Lake was constructed as a surface water reservoir to collect rainfall and flows from Bois d’Arc Creek. This required construction of the 70- MGD Leonard Water Treatment Plant plus 60 miles of 84 to 94-inch diameter pipeline to transport water from the lake so growing communities across North Texas would have a new source of drinking water treated with the latest ozone and biological filtration technology.
Working with our clients, Black & Veatch, CP&Y, Jacobs, and AECOM, HVJ Associates® provided geotechnical design recommendations for Leonard Water Treatment Plant and approximately 30 miles of treated/untreated pipeline.
Most of the pipeline runs through or along parcels of privately owned land, so proper notification to each landowner was crucial before accessing the project site. The following challenges would need to be addressed during this project:
Geotechnical drilling needed to be completed seamlessly with minimum disruption to the property owners, while working with the survey and design team to fulfill our commitment to drill the specified borings along the pipeline easement.
Working with our partners, HVJ drilled a total of 209 borings for the raw water pipeline, greenfield treatment plant facility and the greenfield treated water pipeline to support recommendations for open-cut pipeline, trenchless pipeline crossings, the treatment facility structures and roadways, and the treatment plant storage lagoons. Subsurface data collected from the borings was used to identify the soil and rock in-situ and laboratory properties to be used in geotechnical recommendations. HVJ also provided bearing capacity and modulus of soil reaction from the borings that were provided at the invert depths of the pipeline.
HVJ delivered Geotechnical Data and Design reports for the pipeline and treatment facility, which included detailed Geology description and subsurface site conditions. HVJ translated this into critical guidance for the contractors.
HVJ's guidance enabled contractors to avoid last-minute surprises and prevent costly construction delays. Additionally, because our team was local and familiar with the treatment plant site conditions from our data report, we were able to quickly respond in person on behalf of our client for field questions during construction.
