Explanation
§ This amendment will create a Guaranteed Maximum Price (GMP) for additional storm drainage improvements and streetscape improvements along 16th Street, which will now be included as part of the Upper Little Sugar Creek Tributary Sanitary Sewer Project (Council District 1).
- The CLTWater project occurs along the same road as the storm drainage and streetscape improvements projects. It was discovered through the design process that combining these projects would minimize the impact to residents and decrease the length of time for closure of 16th Street.
- Storm drainage improvements will include an approximate 1,500 linear foot culvert along 16th Street from North Tryon Street to the Charlotte Area Transit Blue Line Extension tracks. This culvert will reduce flooding at the intersection of North Tryon and 16th Streets and support upstream drainage improvements.
- Streetscape improvements will include a two-lane roadway, bicycle lanes, planting strips, sidewalks, and street lights along 16th Street from North Tryon Street to Parkwood Avenue.
§ Sanders Utility Construction Co., Inc. has established a GMP for this additional work, which is the total price for the construction. The GMP will be awarded as an amendment to the Phase 2 contract referenced above.
§ This contract alleviates sewer capacity needs, allows for future development, and rehabilitates aging sections of the sanitary sewer collection system serving the areas.
§ During the design phase, collaboration between City departments identified three current projects in design along 16th Street. By partnering and combining these projects, cost effectiveness is ensured and efficiencies gained, including reducing the duration of the road closure during construction.
§ On November 27, 2017, Council approved the Design-Build Phase 1 contract in the amount of $1,979,256.83 for preconstruction services.
§ On April 9, 2018, Council approved contract amendment #1 in the amount $19,498,569.90 for Design-Build Phase 2 construction services and establishing a GMP for the sanitary sewer improvements.
§ The new total value of the contract is $31,477,826.73.
