Specifications include, but are not limited to: The Greenville Utilities Commission (GUC) is requesting Bids for the construction, testing, and gassing-up of the NC 11 North Natural Gas Main Extension. The proposed 8-inch MDPE SDR 11, 0.784-inch wall thickness, natural gas main is approximately 2.8 miles in length. The route of the proposed gas main ties into an existing gas main near the US 264 (Martin Luther King Jr. Hwy) onramp from NC 11 (North Memorial Dr) and follows NC 11 (North Memorial Drive) to the North until reaching SR 1514 (Station Mill Rd) when we cross NC 11 (N. Memorial Dr) and follow SR 1514 (Station Mill Rd) Northeast and tie into an existing gas main approximately 650’ northeast of the SR 1514 (Station Mill Rd) & SR 1522 (Futrell-Robeson Rd) Intersection. Construction will be within public road right-of-way. As designed, there is ten (10) horizontal directional drills (HDD), two (2) conventional jack and bore with 12” steel API-5L casing, and the remainder of the construction is designed to be performed by a conventional open trench method. The new gas main is to be pressure tested to 90 psig for a maximum allowable operating pressure (MAOP) of 60 psig. The Greenville Utilities Commission intends to operate the main at 60 psig. The Contractor will be required to deliver a tested, cleaned, purged, and gassed-up pipeline. The Contractor shall make all tie-ins between the proposed NC 11 North Natural Gas Main Extension and the existing 4-inch and 8-inch steel natural gas pipelines. The Contractor shall coordinate the tie-ins of the proposed NC 11 North Natural Gas Main Extension and the existing 8-inch steel natural gas pipeline with the Greenville Utilities Commission.
