Complying With The Drainage Laws!  

Generally speaking, civil engineering is the design and maintenance of public sector construction projects such as roads, large buildings, tunnels, dams, bridges, water supply systems, etc. At GeoTrinity Consulting, Inc., we are proud to offer the San Francisco Bay area with expert civil engineering services for large as well as small projects. With regards to grading, certain projects require specialized grading services to ensure either a level base or a base with a specified slope. GeoTrinity Consulting, Inc. uses the latest technologies and equipment to grade and maintain foundations for buildings, roads or railways, landscapes and other large structures. For drainage, San Francisco also has rigid drainage restrictions when it comes to new construction. GeoTrinity Consulting, Inc. works with architects, supervisors and inspectors to ensure all modern codes and drainage laws are strictly adhered to. 

Phase I & II Sites  

Environmental Site Assessment

Phase I & II Site Assessment – An environmental site assessment (ESA) is a report prepared that identifies potential or existing environmental liabilities. During a Phase I ESA, our inspectors visit the site and test for contaminants and unwanted environmental conditions. The Phase I ESA is regulated by the United States Environmental Protection Agency and is the first step necessary to continue construction.

During Phase I ESA  

Phase II ESA

If during the Phase I ESA a potential hazard is found, a Phase II ESA may be required. During this EPA, a detailed chemical analysis for hazardous substances will be conducted. The most frequent substances tested for are heavy metals, pesticides, hydrocarbons, solvents, mold and asbestos.
