2023 Storm Water Drain Pipe Replacement

Scope: The storm water piping on Hillcrest Lane is in need of replacement. This pipe is an oval, corrugated, galvanized steel pipe and measures approximately forty-two inches wide by twenty nine inches tall by thirty-five feet in length. The new storm pipe to be installed will extend an additional three feet into the influent side, a FES flared end will be on the effluent side which will extend the piping an additional three feet, which will make the total length of the new pipe forty-one feet. There is to be a wing wall installed which will be a total of sixteen feet in length, extending eight feet both directions from the center of the newly installed pipe. This wing wall is to be formed and poured in place by the contractor. The existing pipe runs underneath Hillcrest Ln., and the top of the pipe is approximately eighteen inches below the road surface, the bottom of the pipe is approximately three and a half feet below the road surface. The material to be used to replace the corrugated galvanized steel pipe must be of the standard size forty-two by twenty-nine inches with a FES flared end on the effluent side, the wing wall to be formed and poured shall be installed on the influent side. Corrugated metal piping shall be utilized to complete this project and must meet the specification of NCDOT AASHTO-M-36. Upon completion of the installation of the new pipe and wing wall, granite rip-rap locked together with cement grout will be placed on the effluent side of the ditch bank to prevent future erosion. Hillcrest St. proceeds into a cul-de-sac that becomes Hill Ct., there are currently seven residences that reside on Hill Ct. and the only access is through Hillcrest Ln. To allow access to the residences on Hill Ct. only half of Hillcrest St. can be shut down at any time during the project. Upon beginning of the project notification must be given to the City of Havelock five days in advance to allow notifications to be sent to the residents of Hill Ct. The amount of asphalt pavement that is to be removed and replaced during the course of this project is approximately 625 square feet (25' X 25'), see section 7 under pavement restorations for specifications. There are concrete sidewalks on both the North East and North West sides of Hillcrest St. Both sidewalks are fifty-two inches wide. The concrete sidewalks are to be removed along both sides of the street and be replaced with a new concrete sidewalk. The concrete sidewalk to be removed on the North East side of Hillcrest St. shall be the same size as the utility cut at 25'. The concrete sidewalk on the North West side of Hillcrest St. is one hundred and four feet and begins at the driveway of 109 Hillcrest, the end of the new sidewalk will be 38' beyond the driveway for 107 Hillcrest, see section 9 under sidewalk restoration for specifications. The ground along the Northwest side of Hillcrest is degraded and will have to be rebuilt before the sidewalk can be replaced. All measurements are approximate and it will be the contractor's responsibility to verify. The driveway for 107 Hillcrest will be replaced to the first expansion joint, this driveway is broken in several places due to root intrusion from a gum tree next to the driveway, see figure 3. Before the driveway is replaced the tree is to be removed, the stump is to be ground, and the roots intruding into the driveway are to be removed. There is an existing 12" RCP pipe under the driveway of 107 Hillcrest, this pipe is to be replaced with a 15" RCP pipe. See section 8 for pavement restoration specifications. The utilities owned by the City of Havelock running down Hillcrest St. are gravity sanitary sewer and Water. See Figure 1. The Gravity Sanitary Sewer line is an eight-inch terracotta main and is approximately four feet below the road surface. The water main which begins on Hillcrest is a six-inch main although the size is unknown as it crosses beneath the storm water drainage pipe. This water main is approximately three and a half feet beneath the road surface. If either the terracotta gravity sanitary sewer pipe or the water main is damaged during the course of this project it will be the responsibility of the contractor to make the needed repairs to these utilities. It will be the responsibility of the contractor to have all utilities located before work is to commence. Disturbance of existing landscape features shall be held to a minimum and all disturbed areas returned to a condition equal or better once the repair is completed. Care shall be taken so as not to damage existing features to remain such as roadways, curbs, driveways, sidewalks, etc. All features removed or damaged shall be replaced or repaired to existing condition or better. All demolished material shall become the property of the contractor and shall be removed from the work site and disposed of in accordance with all local, State, and Federal requirements. As-built documentation shall include a description of materials used and repair procedures completed at each site. A site visit is highly recommended before submitting a bid. The City of Havelock shall not be held responsible for omissions or errors Questions must be received by 2:00 PM (EST) on Friday, September 8, 2023. If questions are received, the City will respond no later than 12:00 PM (EST) on Wednesday, September 13, 2023
