Pipeline Management Program FY 2020-21 – Phase 1

CLIENT: City of Glendale


Project Value: $6M

Project Description:  W.A. Rasic Construction’s services were secured to design and build multiple sections of “high failure risk” eight-inch distribution water mains and related facilities for the City of Glendale. The initial design phase of this piping replacement project involved digging exploratory excavations to locate existing utilities, reviewing existing utility drawings, geotechnical investigations, survey and mapping, and preliminary pipe routing. Coordinating closely with the City of Glendale and designer Civiltec Engineering, 12 sections of eight-inch ductile iron pipe (DIP) were designed and permitted. W.A. Rasic Construction installed more than 12,000 linear feet of eight-inch DIP, ran approximately 200 water services ranging in size from one to four inches, and constructed approximately 25 fire hydrants in existing streets in 10 months. The water main pipe sections were installed, tested, disinfected, and connected to the existing system with 35 mainline tie-ins, the largest of which was to an existing 30-inch water main. W.A. Rasic Construction conducted extensive public notification efforts to residents and business owners who were affected by the work to minimize disruption to the customers. Our scope also involved replacing paving and related facilities as well as abandoning the existing water mains and services. W.A. Rasic Construction self-performed a GPS survey of the line during installation to create electronic as-builts that were integrated into the city’s GIS system.
