Frontera Force Main Emergency Contract – Phase 1

This design-build emergency installation of approximately 7,200’ of 36-inch FRP force main featured fast-paced, creative, and highly adaptive thinking to bring it to life. The design was completed from project start to the pipe being ordered in six months including full geotechnical research and analysis, subsurface utility investigation, route studies, pressure and flow calculations, complete survey studies, full easement acquisition, traffic control plans, and overall seamless project sequencing. The project was broken into a multitude of different installation methods to work around existing utilities, infrastructure, buildings, homes, and general topography in the area. The bulk of the installation was 4,995 lf of open cut, followed by 1,042 lf of tunneling, 936 lf of slip lining, and 267 lf of jack and bore. The project also included several new header pipe/valve installs at a lift station and pump station, deep open cut pipe installation, several large utility under crossings, large diameter hot taps, bypass pumping, heavy ground dewatering, and street restoration. The majority of the project was installed in highly congested areas.
