This document provides details for a federal contract opportunity to construct seepage relief wells. The solicitation will be issued by the U.S. Army Corps of Engineers Engineering District Memphis on or around March 18, 2019, with proposals due on April 18, 2019. The resulting contract will be a five-year Indefinite Delivery Indefinite Quantity Multiple Award Task Order Contract for between $10-40 million. The scope of work includes construction of relief wells and repairs to existing wells, construction of earthen berms, clearing and grubbing, excavation and placement of borrow material, drainage improvements, grading, drilling, and establishment of vegetation. Eligible firms must have a North American Industry Classification System code for small construction projects and less than $36.5 million in average annual revenue. The government intends to award up to five contracts to small businesses. Evaluation will consider past performance, technical approach, and price for a prototypical task order.
