Project A – E. 8th Avenue Water Main Replacement: Construction of approximately 2,600-feet of 8-inch diameter C900 PVC waterline along East 8th Avenue between Main Street and Sherman Street. The project also includes pavement removal and replacement, hydrant connection and replacement, installing valves, fittings, service connection materials and miscellaneous appurtenances. Contractor shall provide 4-6 inches of rotomilling of the existing pavement at a maximum width of 8-feet and millings to be either reused as the temporary road patch upon completion of the water system installation if paving cannot be performed upon completion of project or transported to City storage facility. The Contractor is responsible for stabilization and final roadway paving. Which will include the installation of Portland Cement soil stabilization material to a depth of 12” and to include all compaction and repaving the street section with 2” bottom mat of Class S HBP and 2” top lift of Class SX HBP. The Contractor shall be responsible for excavation and installation of water mains, valves, valve boxes, tees, crosses, fire hydrant replacement and connection, couplings and applicable appurtenances. The Contractor shall be responsible for all applicable traffic control, per MUTCD standards. The existing 8” water main to be replaced shall be removed and disposed. Contractor will be responsible for locating and excavating around existing utilities and services located in the roadway. The City will tap and reconnect all services within the project. It is anticipated that multiple ¾” services may require the Contractor to excavation from main to meter pit to install new service and backfill. Will entertain other means of installation including directional boring, line pulling, etc. Fire hydrant replacement shall include the installation of tee, 6” valve, 6” fire lateral ductile iron piping, tracer wire, fittings, corrosion protection and other necessary appurtenances. Fire hydrant connections shall include connection to existing 6” valve, 6” fire pipe lateral, tracer wire, fittings, and other appurtenances from the tee including corrosion protection. Due to the proximity of existing storm water infrastructure, the potential for the installation of deflection elbows and/or pipe elevation adjustments may occur in field during the project implementation. All fittings and connections to the main including valves, tees, couplings and other cast appurtenances shall include corrosion protection including plastic wrapping and waterproof coatings on bolts utilized. All piping shall be fitted with solid core copper locating wire with access points for connection located in tracing wire access boxes, meter pits and/or fire hydrants. Excluding meter pits all tracer wire access points will be installed within a special wire access box. Temporary water shall be provided to residential homes and businesses during construction as needed. Proposed procedures for providing temporary water service to all affected properties, and proposed notification procedures for shutdowns, conversions to/from temporary water, and emergencies must be included as part of this submittal. For unforeseen water services encountered, the Contractor shall notify the City Representative immediately.
