Services
ALTA Surveys
ALTA surveys provide precise boundary documentation for commercial properties, meeting lender and title company requirements. Our surveys include easements, access points, and compliance checks with local zoning laws. Using Trimble GPS technology, we ensure accuracy and adherence to ALTA/ACSM standards, delivering reliable data for insurance and development projects.
Construction Staking
We offer construction staking services to guide infrastructure projects with exact measurements for utilities, structures, and grading. Our licensed surveyors use CAD plans and Trimble equipment to ensure alignment with approved designs. This service minimizes errors, reduces rework, and ensures cost-effective project execution for public works and private developments.
Subsurface Utility Scanning
Our subsurface utility scanning identifies hidden pipes and cables using ground-penetrating radar when as-builts are unavailable. This prevents damage during excavation and ensures safe project execution. The Vacmaster 4000 system provides real-time data, allowing precise mapping of underground utilities for construction and maintenance projects.
Photogrammetry
Photogrammetry services create detailed topographic maps and orthophotos for large sites over 5 acres. Aerial imagery captured via drones integrates with CAD software, offering accurate elevation models and site analysis. This technology accelerates design processes and supports planning for residential, commercial, and infrastructure developments.
GPS Control Surveys
GPS control surveys establish precise coordinates tied to the California State Plane System for large-scale projects. Using Trimble R6 receivers, we deliver RTK and static GPS data to ensure alignment with benchmarks. This service supports construction, mapping, and engineering projects requiring high-accuracy spatial reference frameworks.
