The project was constructed in multiple phases during specific yearly work windows. Work consisted of constructing three new concrete vaults along the alignment of Bay Division Pipelines No. 3 and 4, housings for five new in-line valves, and a new steel pipe at three crossover locations. An emergency power facility including a propane generator and tank, SCADA systems, and a VSAT dish with accompanying pole were installed at each site. The pipe crossovers range from 72 to 90 inches in diameter.
