MACA 258051 - Replace Seasonal Housing

The National Park Service seeks construction of seasonal employee housing at Mammoth Cave National Park in Kentucky under a Total Small Business Set-Aside, with proposals due July 22, 2026. This is a firm fixed price contract with a project magnitude between five million and ten million dollars.

Place of performance is Mammoth Cave National Park in Edmonson and Warren Counties, Kentucky. The project comprises two phases: Phase 1 involves construction of up to two new prototype two-story housing structures, one storage building, and associated site amenities and landscape restoration; Phase 2 encompasses demolition, remediation, and landscape restoration of three existing single-story housing structures. The contractor must commence work within 10 calendar days after Notice to Proceed and complete all work within 425 calendar days. Performance and payment bonds equal to 100 percent of the original contract price are required within 10 days of award, and an offer guarantee of 20 percent of the total proposal price (or three million dollars, whichever is less) is required.

The procurement requires Davis-Bacon wage compliance per Kentucky General Decision KY20260015, with prevailing wage rates effective through December 31, 2026. Liquidated damages are set at one thousand three hundred forty-nine dollars per day. The contractor must maintain a minimum 15 percent self-performance requirement. Three separate individuals are required for Superintendent, Site Safety and Health Officer, and Quality Control Manager roles. The site presents karst terrain challenges; the geotechnical report recommends subgrade remediation, maximum net allowable bearing pressure of 2,500 pounds per square foot for shallow foundations, and additional subsurface exploration in northern site areas.

Source selection uses best value with evaluation factors of technical approach (most important), project experience, schedule, key personnel experience, and past performance combined as approximately equally important to price.
