CGI Technical Services performed a geotechnical study of the proposed three-story student services building at Simpson College, in Redding California. The structure is about 30,000 square feet and rests on shallow foundation systems. Services provided included geotechnical engineering investigation, special inspections, and sampling and testing of soils.

The site was explored using deep excavations and an extensive laboratory program was completed to help CGI Technical Services evaluate allowable bearing capacities for the structure, which has relatively large column and continuous foot loads. The extensive laboratory testing and geotechnical evaluation allowed CGI Technical Services to reduce conservatism and, ultimately, saved Simpson College money on construction of foundation systems.

CGI Technical Services performed a geotechnical study for this project that involved construction of a three-story metal-framed building, on an approximate 4-acre parcel. The building encompasses approximately 10,000 square feet in plan area. The building consists of a three-story metal-framed structure with concrete slab-on-grade floors. Asphalt concrete pavement for parking areas and driveways covering the majority of the remaining site. Appurtenant construction includes retaining walls, underground utilities, storm drainage and landscaping. Services provided included geotechnical engineering investigation, special inspections, and sampling and testing of soils

CGI Technical Services provided geotechnical engineering and construction materials testing and special inspection services during construction of the Best Buy Retail Outlet located in Redding, California. The project consisted of a single story 30,000 square foot masonry and steel-framed building with a concrete slab-on-grade. The structure is founded on continuous and isolated foundations. Services provided included geotechnical engineering investigation, and special inspection and sampling and testing of: soils, structural masonry, concrete, structural steel and welding, high strength bolts and bolting, and chemical and mechanical anchorages.

Prior to development, this site was underlain by soft compressible soils that would have exceeded settlement tolerances if not mitigated. CGI Technical Services performed an extensive exploration, testing, and analytical program to identify options to reduce anticipated settlement to within acceptable tolerances. After evaluating these options, a preferred alternative was identified and constructed.

CGI Technical Services provided geotechnical services for the expansion and rehabilitation of these airports. The projects involved an extensive exploration and laboratory testing program at each airport to evaluate CBR values and subsurface geotechnical conditions. Those values were utilized to estimate the modulus of subgrade reaction so that concrete pavement sections could be prepared for the proposed improvements. In addition, the CBR values were provided for use in asphaltic concrete pavement section design for apron rehabilitation and reconstruction, and for the expansion and construction of new taxiways.

CGI Technical Services provided geotechnical engineering, construction materials testing and special inspection services during construction of the new medical office buildings and street improvements located in Yreka, California. The project consisted of three, two-story buildings with cast-in-place concrete slab-on-grade floors. The structures are founded on continuous and isolated foundations. Services provided include preparation of the geotechnical engineering report, observation, and testing during site grading, testing and special inspection of reinforcing steel, concrete, and structural steel and welding.

CGI Technical Services provided geotechnical engineering, construction materials testing, and special inspection services during construction of the Cost Plus World Market Retail Outlet located off Hilltop Drive in Redding, California. The project consisted of a single story 19,000 square foot masonry and steel-framed building with a cast-in-place concrete slab-on-grade. The structure was founded on continuous and isolated foundations. Services provided included geotechnical engineering investigation, special inspections, and sampling and testing of: soils, structural masonry, structural concrete, structural steel and welding, high strength bolts and bolting, and chemical and mechanical anchorages.

CGI Technical Services performed an extensive exploration, testing, and analytical program to identify options to reduce anticipated settlement to within acceptable tolerances. After evaluating these options, a preferred alternative was identified and constructed.

CGI Technical Services provided geotechnical engineering and/or construction materials testing and special inspection services during construction of the four phases of the Hilltop Commercial Developments, located in Redding. Those projects totaled over 150,000 square feet of single-story masonry and steel-framed buildings with cast-in-place, concrete slabs-on-grade. The structures house Pier 1, Michael’s, T.J. Max, Bed Bath & Beyond, Cost Plus World Market, and Best Buy stores and were founded on continuous and isolated foundations. Services provided included geotechnical engineering investigation, special inspections, and sampling and testing of: soils, structural masonry, structural concrete, structural steel and welding, high strength bolts and bolting, and chemical and mechanical anchorages.
