The project involved comprehensive site preparation, including erosion control measures like installing silt fences, protecting inlets, and stabilizing stockpiles. Demolition work included removing concrete, asphalt, and existing structures. Earthwork tasks covered site grading, importing fill material for building pads and parking areas, and topsoil spreading for landscaping. A modular retaining…
The Hillis Group started this project by placing erosion controls, including the installation of compost filter socks, inlet protection using concrete blocks, fabric, and stone, erosion control blankets, and the temporary stabilization of topsoil piles with seed and mulch. Demolition activities of the old asphalt and concrete were then carried…
The project for JW Didado included providing Ground Penetrating Radar location services prior to excavation. The team demolished one circuit breaker foundation entirely and partially removed four bus support foundations to 6 inches below the finished grade. Mechanical excavation and backfill were performed for concrete foundations, which were then formed…
In early 2024, The Hillis Group undertook a project in upstate New York for the client to capture methane gas from a manure pond and connect it to a compressor station. The Hillis Group performed the groundwork necessary for the construction of the compressor station. Installation of a 20′ wide…
Existing site conditions would not allow a typical drainage basin to manage the storm water runoff created from a new natural gas compressor station. Engineers designed an underground filtration and storage system to handle the storm water runoff. Our crew excavated and installed the underground storm water management tank system…
The Hillis Group was contracted to mitigate an area of existing pipeline right of way that has been plagued with ditch line subsidence. This project consisted of removing asphalt driveways and pedestrian walk paths to excavate compromised soils around and under the existing pressurized natural gas pipeline. Sloping and trench…
