Installation of Floating Wetland Islands (Construction Services)

NC State University's Biological and Agricultural Engineering Department is soliciting proposals for construction services to install floating wetland islands on two wetponds at the Brunswick County Government complex in Bolivia, North Carolina, with proposals due October 22, 2026 at 2:00 p.m.

The scope covers design, sourcing, and installation of floating wetland island systems on the North Pond (550 square feet coverage) and South Pond (1,300 square feet coverage) to improve water quality performance. The contractor must source and install wetland vegetation at a minimum planting density of 0.5 stems per square foot, provide anchor systems, and deliver a six-month plant warranty guaranteeing 85% plant survival and surface coverage with replacement of dead vegetation at no additional cost. The floating island system must have a verified structural design life of at least three years under continuous immersion. The cost proposal must be a lump-sum price covering all mobilization, travel, permitting, site setup, cleanup, materials, planting labor, and warranty for both locations. Routine maintenance costs are excluded from contract scope.

The contractor must demonstrate a minimum of three years of in-depth experience and provide three relevant project references from similar work completed within the past three years. Insurance requirements include Workers Compensation (minimum $500,000 employer's liability), Commercial General Liability ($1,000,000 combined single limit), and Automobile Liability ($1,000,000 combined single limit).

The project must be completed, inspected, and accepted within six weeks from award (estimated November 2026). Evaluation weights technical proposals at 60% (40 points for project approach and resources; 20 points for qualifications and experience) and cost proposals at 40%. Questions are due October 5, 2026 at 5:00 p.m. No site visit or pre-proposal conference is mandatory, though the University encourages contractors to explore the public site independently at their own expense.
