MISSION BAY N1
SAN FRANCISCO, CALIFORNIA

This project is directly across from SBC Park and allowed Consolidated Engineering Laboratories (CEL) to form a joint venture with a disadvantaged business enterprise to provide materials testing and special inspection services on this complex concrete project. As a lead partner in the joint venture, CEL coordinated the overall activities of the project quality assurance program, including reinforced and post-tensioned concrete, masonry, structural steel welding, high strength bolting, insulation, and some curtainwall inspections. This project consists of two 17-story towers and three nine-story buildings built on a retail podium with associated parking, and over 70,000 cubic yards of concrete. The project was performed using a multiple shift operation with much of the concrete placed in the early morning hours and the utilization of flying forms which caused each floor to "turn" in nine days.
