Scope: The current existing drainage piping is approximately 105 feet of 24" galvanized steel corrugated pipe. The current elevation of the base of the pipe is approximately four feet beneath the top of the asphalt. It is to be replaced with a 36" HDPE Bell and Spigot pipe. The City of Havelock will supply 120 feet of 36" HDPE Corrugated Bell and Spigot piping, see figure 2, it will be the responsibility of the contractor to load and move the piping from its current location at 41 Lynnwayne Circle to 400 McCotter Boulevard Havelock, NC. 28532., see section 1 for pipe removal, see Section 2 for pipe installation. Work hours for this project will be 7:00 am to 5:00pm Monday thru Friday, any work needed beyond these hours must be approved 48 hours in advance and is subject to approval by a representative of the City of Havelock. All measurements are approximate and contractor to verify. Contractor will be responsible for all locating services. Contractor will be responsible for damage to any and all utilities during the course of this project.. ABC or 57 stone will be brought to asphalt elevation and compacted to 95% standard proctor in eight in lifts. There is a headwall at the upstream and downstream ends of the existing 24" piping. These headwalls are to be removed and once the new 36" HDPE Corrugated Bell and Spigot piping is installed, new headwalls are to be poured in place on both the upstream and downstream ends. The existing headwall is approximately 24 feet long, 12 inches wide 4 feet deep; the new poured in place headwall will remain the same dimensions. Once the new headwall has cured and any forms are removed, Rip-Rap is to be placed on both the upstream and downstream ends of the pipe. Pavement restoration will be the responsibility of the contractor. All measurements are approximate and contractor to verify.. Removal of the existing 24" Drainage Pipe - a. Contractor shall create two straight lines on the asphalt which shall remain no less than sixteen inches away from any permanent structures. The total width between the two lines shall be five feet. On the downstream side of the drainage pipe there is a twelve by twenty-foot area of the asphalt that is deteriorating, this area must be cut back square. b. Contractor shall utilize sheet piling when the excavation is closer than five feet from the existing buildings to stop any undermining of the existing structures. Any damage to the existing structures created by excavating will be the responsibility of the contractor. Damage to any utilities due to the excavation will be the responsibility of the contractor. c. A repair was made on this 24" Drainage Pipe several years in the past, as a preventative measure concrete was poured on the repair area. The contractor will be responsible for removal of approximately a 108 cubic foot block of concrete before the installation of the new 36" HDPE Bell and Spigot piping. d. Contractor shall cut the asphalt following the straight lines with an abrasive blade that will leave a clean ninety degree cut. e. Contractor shall excavate for the removal of the existing 24" drainage pipe. The trench that is to be excavated will be no less than five feet wide for the installation of the new 36" drain pipe. f. Contractor will be responsible for bypass pumping of the flow coming into the area of excavation. Bypass pumping shall continue for the entirety of this project. g. All removed pipe and excavated spoils become the property of the contractor and must be removed from site.

Contractor shall excavate ten inches deeper than the elevation of the base of the 24" drainage pipe. The base elevation of the new HDPE piping will be four inches deeper than the base elevation of the removed 24" drainage pipe. The remaining six inches will be backfilled with 57 stone for HDPE pipe bedding, see figure 3. b. The contractor will place the HDPE Corrugated Bell and Spigot Piping carefully on the prepared foundation of six inches of 57 stone bedding starting at the downstream end with the inside circumferential laps pointing downstream and with the longitudinal laps at the side of quarter points. c.
