RFQ# 18-05-24 Architectural and Engineering Consulting Services: Construction Testing and Inspections RFQ# 20-70-01 Continuing Professional Consulting Services System. Soil samples were tested in the laboratory to establish the soil properties and confirm the visual classification. The laboratory testing included grain size analysis, moisture content tests and organic content tests. Provided a Roadway Soil Survey Report for the project which included geotechnical evaluations and recommendations regarding permanent cut and fill slopes, excavations, groundwater control, pavement design considerations, and on-site suitability. Completed on time and within budget in 2020 SW 328 Street from US-1 to SW 162 Ave., Miami-Dade County, Florida. TSF is currently providing Construction Material Testing Services for SW 328th Street form US-1 to SW 162nd Avenue in Miami, Florida. TSF services included laboratory testing, soils and reporting. Sampling and Laboratory Testing includes modified proctor testing, LBR testing, sieve analysis and sample pick-ups. TSF technicians provide in-place density testing and compressive strength testing; conducted slump and temperature testing on concrete. A TSF Senior Engineer is providing review of daily reports, coordination, and attended meetings as necessary. The project is currently on-going Roadway Reconstruction NE 3rd Ave. From NE 54th St. To NE 58th Terr., Miami, Florida. Performed geotechnical data collection for the NE 3rd Ave. Roadway Reconstruction from NE 54th St. To NE 58th Terr. in Miami, Florida. The purpose of the geotechnical data report is to provide general information on the subsurface conditions at the project site. Field work included auger borings along NE 3rd Avenue, including pavement cores; and BHP test to determine the hydraulic conductivity of the subsoils for drainage improvements. Preformed Limerock Bering Ratio (LBR) test for subgrade. Provided Geotechnical Data Report. Completed on time and within budget in 2017 I-95 Express Lanes in Broward and Miami-Dade Counties (Design-Build) from the Golden Glades to Broward Blvd., Broward and Miami-Dade Counties, Florida.
