Augusta Road Water Main

Davis & Floyd is nearing the end of construction on Greenville Water’s Augusta Road Water Main project. This large-scale water resources project involved the installation of new 6”, 8”, 12”, and 24” water mains to connect gaps along Greenville Water’s existing network in the congested Donaldson Center area. Ultimately, the project included installation of 8,261 LF of 24”, 4,028 LF of 12”, 120 LF of 8”, and 175 LF of 6” ductile iron water main. It also involved installation of three 24” inline butterfly valves in a concrete vault as well as hydrants and air release valves. Additionally, the project included resurfacing work on US 25.

Our team coordinated and worked with Greenville Water‘s project manager and engineers to design alignments to avoid wetlands to the extent possible except for open cut installation of the 12” water main under Huff Creek, permitted under the Nationwide Permit program with USACE. Our engineers worked with Greenville Water’s modeling engineer to provide hydraulic calculations using their existing hydraulic models. We also developed the traffic control plan for the work in the SCDOT right-of-way and provided construction inspection services. As this project crossed over many driveways and utilities, it required frequent, careful coordination with property owners and utility providers during design and construction to keep the project running smoothly. We adjusted plans and bid documents to reflect value-engineered solutions provided by the owner and contractor to meet the owner’s budget. We also developed a design report with calculations for the SCDHEC permit application.
