The Santa Barbara Municipal Airport T-Hangers project involved the demolition of several existing structures, earthwork to construct building pads, cement treatment of areas to be paved, placement of concrete foundations and slabs-on-grade, and erection of 24 general aviation aircraft hangars. For this project, Earth Systems conducted a soils engineering investigation entailing subsurface exploration, soil classification and sampling, laboratory testing of samples, and development of geotechnical criteria to be used to guide the preparation of plans and specifications. During construction, we provided observation and testing services during earthwork operations for the building pads and the taxi lanes, and during cement treatment operations. Additionally, Earth Systems provided special inspection of concrete for foundations and slabs-on-grade, anchor bolts, and structural steel for the hangar buildings.
