The successful respondents will provide a range of services for various/periodic projects that support TSTC’s infrastructure needs. These services may include but are not limited to: Geotechnical Engineering ● Provide desktop review of generally available public information for selected sites. ● Conduct field exploration at selected sites, including drilling/sampling of subsurface materials and observation of current groundwater levels. ● Conduct laboratory testing of collected subsurface materials. ● Provide engineering analysis and geotechnical recommendations in written report format for the proposed project. Construction Materials Testing ● Soils - Sampling/testing of soils, observation of earthwork operations, and moisture-density testing of subgrade and compacted fill. ● Cast-in-Place Deep Foundations - Pier/pile diameter, depth, bearing stratum, and reinforcing steel observation as well as compressive strength testing of concrete/grout. ● Concrete - Sampling concrete and conducting slump and concrete compressive strength tests. Observe formwork dimensions, reinforcing steel size, spacing, and configuration prior to concrete placement. Verification of anchor bolt diameter, length, shape, and concrete embedment. Verification of bolt hole size, depth, and cleanliness as well as the application of epoxy and installation of bolts for epoxied anchor bolts...
