In a very congested area of San Francisco, ARB completed a gas distribution project for Pacific Gas and Electric. The work involved, utilizing a mini horizontal directional drilling rig for the installation of 5,000 ft of 2-inch polyethylene natural gas main for main and service replacement work. The directional drilling method allows the work to take place with much less inconvenience to the public by reducing the number of excavations. ARB crews also replaced 210 services to homes and rebuilding all meter sets.
