Explanation
§ The Doby Creek and Little Sugar Creek Tributary to Fairview Road gravity sewer lines serves residences and businesses along the Blue Line Extension in the northeast and SouthPark area of Charlotte, respectively.
- These gravity sewer lines are 40-50 years old and cannot accommodate projected growth within the respective service areas. The areas served by these two lines have experienced changes in land use.
§ The City will use the Construction Manager at Risk (CMAR) project delivery method to provide more certainty with respect to project cost and schedule, mitigate risk during construction, enhance Minority/Woman/Small Business Enterprise participation, and allow for more effective coordination of construction and start-up activities with the City.
§ On April 13, 2017, the City issued a Request for Qualifications; two responses were received from interested service providers.
§ Garney Companies, Inc. best meets the City’s needs in terms of firm and project team member experience.
§ The contract with Garney Companies, Inc. will provide for the CMAR’s preconstruction services during design. Preconstruction phase services include working collaboratively with the City and the Design Engineers, Hazen & Sawyer, and STV Engineers, Inc., to identify and mitigate risk, develop project schedules, develop construction cost estimates and bid packages, perform constructability reviews, and to establish and negotiate the guaranteed maximum price.
§ The CMAR project delivery method will require one additional contract for the construction phase, which will be brought to the City Council in early 2018. The construction phase of work is anticipated to be completed in the first half of 2019.
§ Garney Companies, Inc., as the CMAR, will not be allowed to self-perform the construction work. The company will bid out work to subcontractors.
§ Garney Companies, Inc. will be responsible for managing the subcontractors work and delivering the project on schedule and on budget.
