Services
Land Surveying
Our land surveying services provide precise boundary determinations and topographic mapping for commercial and residential developments. Using GPS and 3D scanning technology, we deliver ALTA/ACSM surveys, utility detection, and construction staking with exceptional accuracy. Our experienced surveyors support projects ranging from small residential lots to large-scale urban developments.
Civil Engineering
We offer comprehensive civil engineering solutions including site development, drainage systems, and infrastructure design. Our engineers create grading plans, stormwater management systems, and utility designs that meet all regulatory requirements. With expertise in LEED certification and ADA compliance, we support educational, commercial, and industrial clients throughout Southern California.
3D Laser Scanning
Our 3D laser scanning captures detailed as-built conditions for building information modeling. Using Faro Focus scanners, we create precise point cloud data for architectural renovations and structural analysis. This technology enables efficient Scan-to-BIM workflows that improve project accuracy and reduce rework for complex building systems.
Building Information Modeling
We convert laser scan data into intelligent 3D BIM models using Revit software. Our BIM services support architects, contractors, and facility managers with accurate digital representations of existing structures. This technology enhances coordination between mechanical, electrical, and structural systems during renovation projects across various building types.
ADA Compliance
Our ADA compliance services ensure facilities meet federal accessibility standards through detailed path-of-travel assessments. We create accessible route plans and design modifications for educational institutions and public buildings. Our engineers have extensive experience implementing ADA requirements in both new construction and renovation projects for school districts across Southern California.
