For example, the ports regularly compete for customers, and they joined forces to launch the Alameda Corridor. Construction began in 1997 with substantial completion on time and on budget in April 2002. The scope of this accomplishment is demonstrated by the various project elements and materials listed here: * 51 separate bridge structures * 1,700 relocations of underground and overhead utility operations * Uninterrupted rail service during construction * 1 million cubic yards of concrete * 150 million pounds of rebar re·bar n. 1. A rod or bar used for reinforcement in concrete or asphalt pourings. 2. A group of such rods forming a grid. [re(inforcing) bar.] * 800 million pounds of rock for railway ballast * 4 million cubic yards of dirt excavated for the Mid-Corridor Trench * 27,000 pilings poured for Trench walls * 2,200 concrete struts, each weighing about 50,000 pounds, installed across Trench * 900 million pounds of previously contaminated contaminated, v 1. made radioactive by the addition of small quantities of radioactive material. 2. made contaminated by adding infective or radiographic materials. 3. an infective surface or object. soils disposed of properly. |
