Presolicitation notice: The Department of the Interior, National Park Service, plans to replace the septic tank and drainfield at the Volunteer in the Park (VIP) Recreational Vehicle (RV) Pads on Fort Raleigh National Historic Site. The existing system is past its useful life and does not properly drain. The new septic system will meet North Carolina Building Code and will be installed by a qualified installer. The project includes emptying the existing septic tank, demolishing the existing concrete septic tank and drainfield components, removing designated trees and roots, removing unsuitable soil, providing a new 1,000 gallon concrete septic tank, providing a new distribution tank and infiltrator chamber drainfield, and hydroseeding the disturbed areas. The procurement is set-aside for small business concerns and will be awarded as a firm-fixed price contract. The period of performance is 90 days. Offerors must be registered in the System for Award Management (SAM) to participate.
