Civil Construction

What We Do

SapperSix provides heavy civil construction services for federal facilities, utilities, transportation infrastructure, and industrial sites. Our work spans excavation, grading, demolition, and site development—executed with Lean construction principles, safety discipline, and quality controls designed to meet the stringent requirements of government and regulated contracts. Every project is managed with schedule accountability, cost control, and full compliance documentation.

Civil Construction Services

  • Mass excavation, trenching, backfill, compaction, and soil stabilization for infrastructure and site development projects. Work includes utility trenches, foundation excavation, and large-scale earthmoving operations.

  • Rough and fine grading for building pads, roadways, drainage systems, and access improvements. We provide survey-grade precision for complex grading projects requiring tight tolerances and engineered specifications.

  • Land clearing, vegetation removal, tree removal, stump grinding, and debris hauling. Site preparation includes demolition of existing improvements, removal of underground obstructions, and preparation for new construction.

  • Structural demolition, concrete removal, asphalt removal, and selective demolition. Services include saw-cutting, core drilling, jack-hammering, and precision demolition in occupied facilities or sensitive environments.

  • Removal of slabs, foundations, retaining walls, utilities, and underground structures. Concrete breaking, hauling, recycling, and disposal in accordance with project specifications and environmental regulations.

  • Gravel roads, access routes, temporary haul roads, and permanent paved surfaces. Subgrade preparation, base installation, and coordination with paving contractors for final surfacing.

  • Excavation and installation support for water, sewer, gas, electric, and telecom utilities. Trench safety, shoring, backfill, compaction, and coordination with utility owners and locating services.

  • Installation of drainage systems, catch basins, culverts, storm drains, and detention/retention facilities. Work includes grading for positive drainage and coordination with civil engineers.

  • Shoring, bracing, temporary access roads, erosion control, and construction support structures. Rapid deployment for projects requiring immediate site stabilization or access.

  • Dry and wet utility locating using vacuum excavation and hand digging to expose underground utilities prior to excavation. Hydro-vac services for safe utility exposure in congested or sensitive areas.
