Services
Commercial Surveying
Meridian delivers tailored surveying solutions for commercial projects, including ALTA surveys, construction staking, and boundary analysis. Our team supports developers, contractors, and municipalities with precision mapping and compliance documentation. Utilizing GPS and 3D scanning, we ensure accuracy for large-scale developments like high-rises, roads, and utility infrastructure. Clients benefit from rapid turnaround times and expertise in complex urban environments.
FEMA Elevation Certificates
We provide FEMA-certified elevation surveys to determine flood zone compliance and insurance requirements. Our licensed surveyors assess properties to identify elevation risks and file documentation for potential insurance reductions. With emergency 48-hour service, we help homeowners and businesses navigate floodplain regulations and secure Letter of Map Amendments (LOMAs) when applicable.
3D Laser Scanning
Our high-definition laser scanning creates detailed 3D models for building information modeling (BIM) and structural analysis. This technology captures millions of data points to map complex sites, enabling efficient design and construction planning. Applications include historical preservation, accident reconstruction, and industrial asset management, ensuring clients save time and reduce rework.
Hydrographic Surveys
Meridian conducts bathymetric and inland waterway surveys for marinas, lakes, and rivers. Using advanced sonar and GPS, we map underwater topography for dredging, environmental studies, and infrastructure projects. Our services include independent certification of sediment volumes and integration with land-based boundary data for comprehensive coastal and marine solutions.
Settlement Monitoring
We deploy real-time monitoring systems to track building movement and seismic impacts. Using StabiAlert technology, our 24/7 sensors detect vertical and horizontal shifts, providing critical data for high-rise safety and post-earthquake reoccupation. This service ensures compliance with San Francisco's Building Occupancy Resumption Program (BORP) and protects investments during nearby construction.

Report
Was reaching out to them and was speaking with the representative that requested so many information that was provided through the email they were saying they are interested and they can take on this project. Unfortunately thy never respond back. Suddenly I was calling in and they were saying that their kindly cannot take more projects at the moment and thy refer us to the Yellow Pages to find a survey in Oakland.

Report
I have a degree in mechanical engineering and so I know a lot about what a good surveyor can and should do. I have always been impressed with the technical expertise that Stan Gray and the Meridian Survey team have brought to the projects they have worked on. I would be totally confident to continue use and recommend Meridian Survey for all my future projects. I know sometimes they get busy, but I would even rather wait a little longer to get them on my project because I know it will be done right and to the highest standards.
