A timeline for award has not yet been established. The Commissioners of Public Works of the City of Charleston, South Carolina (Owner) is soliciting a Statement of Qualifications (SOQ) from contractors interested in the opportunity to submit a proposal to provide preconstruction and construction services for the Plum Island Water Pollution Control Plant (WPCP) Phase 4 Capital Improvements Project using the Construction Manager at Risk (CMAR) method of project delivery. The Work to be performed consists of major modifications to the Owner's existing 36 MGD Plum Island WPCP and includes construction of a Biosolids Facility (new dewatering building with five (5) rotary fan presses, sludge feed pumping, polymer make-up and feed, dewatered cake conveyance, truck loading, lab, and space for storage and maintenance), one (1) 110-foot diameter concrete Primary Clarifier, two (2) Final Settling Tanks, Process Control Pump Station (PCPS) Improvements, PCPS Discharge Header Modifications, Sodium Hypochlorite Storage and Distribution Facility, new Odor Control System, and Abandonment/Demolition of Existing Facilities. Most of the structures and major piping will be pile supported. The Work includes, but is not limited to, all piping and valves, grading and paving, sedimentation and erosion control, electrical work, instrumentation and controls, HVAC equipment and all other work necessary to render the facilities complete and operational. The planning level estimated construction cost for these modifications is in the range of $50-65 million. Included in the CMAR contractor's scope of services is collaboration with the design engineer during the design phase, providing constructability and value engineering guidance, development of a guaranteed maximum price (GMP) proposal, and, assuming successful negotiation of a GMP with the Owner, ultimately entering into a construction agreement for the construction of the Project. Responses to this RFQ will be evaluated to identify contractors with the requisite experience, qualifications, and resources to complete the Project successfully within an agreed upon GMP in accordance with project requirements that will be specified by the Owner. The details of the project requirements will be presented in the Request for Proposals (RFP), which will be issued at a later date to a short-list of contractors selected by the Owner who will be invited to respond to the RFP based on an evaluation of their submission to this RFQ. This RFQ will place an emphasis on the contractor's demonstrated ability on past projects of similar size, nature, and scope to self-perform significant portions of construction on the Project with their own workforce. The Project consists of major modifications to the Owner's existing 36 MGD Plum Island WPCP and includes construction of a Biosolids Facility (new dewatering building with five (5) rotary fan presses, sludge feed pumping, polymer make-up and feed, dewatered cake conveyance, solids hopper, truck loading, three (3) holding tanks, lab, and space for office, control room, and electrical room), one (1) 110-foot diameter concrete Primary Clarifier, two (2) Final Settling Tanks, Process Control Pump Station (PCPS) Improvements, PCPS Discharge Header Modifications, Disinfection Facility (sodium hypochlorite storage and distribution), new Odor Control System, and Abandonment/Demolition of Existing Facilities.
