RFQ for Professional Engineering Services Related to the Wastewater Service Due Diligence Preliminary Engineering Report of the Pitt County Megasite North Development

Greenville Utilities Commission (GUC) is seeking professional technical services to develop a Preliminary Engineering Report (PER) for wastewater infrastructure supporting the Pitt County Megasite North development. The Megasite comprises 3,300 acres of industrial-zoned property located in northern Pitt County, North Carolina, north of Greenville. The selected consultant will serve as the foundational engineer for planning, design, and funding applications for sewer infrastructure to support this major industrial development.

The scope of work includes conducting a comprehensive site survey and investigation of existing utility infrastructure, reviewing GUC location maps to identify existing wastewater mains and sizing, and utilizing existing GUC collection system and wastewater plant models to evaluate available capacities. The consultant must estimate immediate and projected future wastewater generation from potential Megasite tenants, develop projections for peak and average demands over the planning horizon considering phased development, and analyze impacts on service to existing GUC customers and the Town of Bethel (which joined GUC approximately 5 years ago).

Key deliverables include identifying and evaluating multiple alternatives for extending and upgrading infrastructure to reliably meet projected wastewater demands, assessing feasibility and environmental impacts, and recommending an optimal alternative. The consultant must develop potential routes and required capacities for recommended improvements, including gravity sewer extensions, a sewer lift station with approximately 10 million gallon per day (MGD) capacity to service wastewater from the Megasite property with upgrade capabilities for future phased development, and force main extensions. Preliminary construction cost estimates must be prepared for major components of each feasible alternative, focused on Phase I improvements. The consultant must identify State and Federal regulatory requirements and permitting processes required for proposed infrastructure development.

A draft PER is due May 2027, with a final PER incorporating feedback from GUC, local planners, funding agencies, and community representatives due October 2027. The consultant must ensure adherence to all state, federal, and local regulations, including conflict-of-interest requirements, procurement rules, and environmental compliance. Grant compliance documentation, reporting obligations, and coordination with county staff, state agencies, and subcontractors are required. The consultant's design team should be familiar with infrastructure work in Pitt County and experienced in large-scale wastewater infrastructure construction in the region.
