Geotechnical Reports

Geotechnical Reports are required for new construction consist of soil borings or trenches, soil sampling, laboratory testing, data analysis and report preparation. The report will provide recommendations for your specific site and proposed construction relative to collapsible soil (settlement), expansive soils, soil classification, soil strength data (i.e. bearing values for foundation design) and chemical analysis of the soil (i.e. sulfates, chlorides, which can react and deteriorate concrete).


Every structure needs a good foundation, but it also needs a good foundation support system. It is important to contact Bruin GSI, in most cases, before you purchase your lot, as special foundation design and/or grading recommendations will affect the cost analysis of your project.

Phase 1-4 Environmental Studies

Phase 1-4 environmental reports are prepared by our Registered Environmental Assessor. The phase 1 report includes a data base research, site reconnaissance and review of historical aerial photographs to detect the possibility of hazardous materials at your site and adjacent properties. Previous uses such as gas stations, farming equipment and the kind could have caused hazardous waste contamination. If hazardous materials or evidence of hazardous materials are detected, a Phase 2 report would be necessary. If the materials are so extensive as to require cleanup, Phase 3 and 4 reports would be warranted.


Ii is important to contact Bruin GSI to perform the Phase 1 report prior to purchasing the property. If you purchase property that contains hazardous materials or if a financial lending institution is involved in your purchase, a Phase 1 report will more than likely be required.
