Geotechnical Engineering Services

The Texas government authority requires a vendor to provide comprehensive geotechnical engineering services. The requested scope includes geological and geotechnical field operations, testing programs, and engineering analyses for bridges, tunnels, retaining walls, slopes, embankments, storm sewer alignments, overhead sign structures, and temporary soil retaining systems. The buyer requires the vendor to furnish calibrated drilling equipment with an automatic hammer, calibrate the hammer system, drill and install piezometers, and perform all foundation exploration, drilling, testing, soil borings, rock coring, logging, and piezometric readings. The vendor must perform specific engineering analyses, including slope stability, settlement, and retaining wall evaluations covering bearing capacity, global stability, overturning, sliding, friction angles, consolidation, and lateral earth pressures. Only onshore US organizations are eligible for this opportunity, and all work performance must occur onsite. The buyer seeks proposals for the budget and requires all questions to be submitted no later than September 17, 2026.
