<br /> <br /> <br /> <br /> <br />RFQ# 18-05-24 Architectural and Engineering Consulting Services: Construction Testing and Inspections <br />RFQ# 20-70-01 <br />Continuing Professional Consulting Services <br /> TSF performed a geotechnical engineering study for the Palm Beach County Convention Center Parking Garage, a 9-level parking garage with basement level parking in West Palm Beach. The purpose of the study was to explore the subsurface conditions at the site to enable an evaluation of acceptable foundation systems for the construction. Field work included SPT borings. Provided geotechnical evaluations regarding the site and subsurface conditions; spread foundation after vibro-compaction; auger cast pile alternatives; utilities; construction excavation and dewatering. Geotechnical recommendations were provided for foundation design and general site development. TSF also provided comments regarding factors that may impact construction and performance of the proposed construction. Prior to construction, TSF performed pre-construction survey services. The purpose of the pre-construction conditions documentation is to document existing conditions (interior and exterior) of adjacent structures, to the south and east of the garage prior to and after completion of vibro-flotation techniques and temporary sheet pile installation that will likely cause ground movement. Our scope of work included assistance in delivering notification letters to property owners and maintain contact records; coordinate and schedule inspections with property owners; visually inspect, videotape and photograph observable existing cracks, deterioration, or other signs of distress. Prior to the start of construction and for each property observed, written reports and photographic records consisting of both video footage and still images were prepared for distribution to the property owners. TSF provided construction materials testing services during the construction phase. Sampling and Laboratory Testing included Modified Proctor values on structural fill, slab and backfill material, utilities; LBR tests on subgrade and base materials; compressive strength concrete cylinders and grout prisms for walls; and compressive strength mortar cubes for pre-cast members. TSF technicians performed In-Place-Density testing on structural fill, slab, subgrade, base and backfill material. TSF also provided Vibro-compaction Verification Borings and vibro-flotation probe installation observation. Completed on time and within budget in 2017 <br />79
