This document provides details for a federal contract solicitation issued by the Department of the Interior Bureau of Reclamation. Solicitation number 140R6021R0024 is seeking proposals for modifications to the Altus East B and Lugert Dikes foundations at the Altus Dam in Oklahoma. Responses are due by April 30, 2022. The solicitation involves repair and reinforcement of the dike foundations to ensure continued safety and reliability of the dam infrastructure. Offerors should have experience with dam and waterway construction projects. The award is expected to be a firm-fixed-price contract issued in July 2022 to the responsible bidder whose offer conforms to the solicitation requirements and is most advantageous to the government considering only price and technical factors.

0.0 to 25.8 ft. - QUATERNARY ALLUVIUM (Qal):

0.0 to 13.3 ft. - Clayey Sand (SC): Approximately 60% fine, subrounded to subangular, hard sand; approximately 40% medium plasticity fines with medium dry strength, slow dilatancy, medium toughness; dark brown from 0.0' to 5.8', red from 5.8' to 13.3'; firm; wet; and no reaction with HCl.

13.3 to 25.8 ft. - Sandy Lean Clay s(CL): Approximately 65% medium plasticity fines with high dry strength, no dilatancy, and medium toughness;

approximately 35% fine to medium, predominantly fine, subrounded to subangular, hard sand; a trace of fine, subrounded to subangular, hard gravel; dark brown to red; firm; moist; and CaCO3 nodules with strong reaction with HCl, no reaction with HCl in surrounding material.

25.8 to 31.8 ft. - QUATERNARY EOLIAN (Qea):

25.8 to 31.8 ft. - No Recovery: Interpreted to be Poorly Graded Sand (SP) due to the core barrel getting stuck inside the augers. Water levels also came to ground surface upon entering this zone with drilling. A very small amount of sand was on top of the core barrel upon removal.

31.8 to 35.8 ft. - PERMIAN HENNESSEY SHALE (Phy):

31.8 to 35.8 ft. - Shale: Red with blue nodules from 31.8' to 32.8', blue from 32.8' to 35.8'; dry; very soft (H7); intensely weathered (W7); joints not discernable; gradational contact at 31.8'; CaCO3 stringers with strong reaction to HCl throughout.
