The contractor must furnish all transportation, equipment, labor, materials, and services necessary to address erosion issues, remove silt and obstructive vegetation, repair erosion damage, place riprap in high-erosion areas, and fill voids around drainage structure headwalls. This is a firm fixed-price contract for commercial items with a 90-day total completion timeline, requiring the contractor to commence work within 10 calendar days of receiving the notice to proceed. Evaluation will be based on cost, technical approach, and relevant experience, with bidders required to provide references of applicable experience to receive the award.

This procurement is designated as a total small business set-aside under NAICS code 237990 (Other Heavy and Civil Engineering Construction), with no incumbent contractors identified in the solicitation documents. The contract value is estimated between $250,000 and $500,000, representing the magnitude of requirement for this drainage infrastructure project.
