Services
Civil Engineering
Our civil engineering team creates comprehensive site designs for residential subdivisions, commercial developments, and campus projects. We specialize in stormwater management, utility design, and grading plans that meet regulatory requirements. Our engineers collaborate with surveyors and planners to ensure projects remain within budget and timeline while maintaining structural integrity and safety standards.
Land Surveying
We conduct ALTA/NSPS and boundary surveys using advanced GPS technology to establish precise property lines and easements. Our surveyors provide data for construction staking, topographic mapping, and legal documentation. This service ensures compliance with municipal regulations and prevents future land disputes through accurate, legally recognized measurements.
UAV Mapping
Unmanned aerial vehicles capture high-resolution topographic data for large-scale projects. This technology enables rapid data collection with millimeter-level accuracy, reducing field time by up to 70%. UAV mapping supports site analysis, progress monitoring, and volumetric calculations for construction and land development projects.
3D Laser Scanning
Our 3D laser scanners create detailed digital models of existing structures and sites. This service provides precise measurements for renovation projects, facility management, and forensic analysis. The technology captures millions of data points per second, generating accurate BIM-ready models that improve design coordination and construction efficiency.
Land Planning
We develop cost-effective land use plans that balance functionality with environmental considerations. Our planners address zoning requirements, infrastructure needs, and community impact assessments. This service includes feasibility studies, site analysis, and master planning for mixed-use developments, ensuring projects meet both client objectives and regulatory standards.

Worked with them for years and our experience is; they've always been on time, usually under budget and extremely professional. You won't pay them to "learn on your job", they know what they are doing and can back everything up.
