Z--Siding Replacement

The National Park Service has awarded a firm-fixed price contract to DDL Group LLC, a small business, for the replacement of siding at Indiana Dunes National Park, with a contract value of $418,485.00. The work falls under NAICS code 236220 and was procured through a sealed bidding process under the Lowest Price Technically Acceptable methodology, where award was determined solely based on price competitiveness and responsiveness to solicitation requirements, with no trade-off analysis. The contract encompasses complete siding installation with associated components such as flashing, vents, and insulation, requiring strict adherence to manufacturer specifications, ASTM standards, and the 2024 International Building Code. Performance is to be completed within 120 calendar days from the Notice to Proceed at the project site in Porter, Indiana, with all inspections and final acceptance occurring on-site by the Contracting Officer. All materials must be delivered in original, undamaged packaging with clear labeling of manufacturer data, production dates, and compliance markings, and must be stored under controlled environmental conditions to prevent damage from moisture, sunlight, or temperature extremes. The contract includes comprehensive clauses for labor compliance, safety standards, whistleblower protections, subcontracting limitations, and anti-kickback provisions, with electronic invoicing mandatory through the Treasury's Invoice Processing Platform. The Contracting Officer, Jarrod Brown of the National Park Service’s Ohio office, is the sole point of contact for administrative and payment matters, with no assigned COR or COTR identified. DDL Group LLC submitted a responsive bid under a small business set-aside, affirming its status and compliance with all required representations, including size certification under the $45 million size standard for NAICS 236220, and no affirmatively disclosed foreign ownership or covered telecommunications equipment. The solicitation required a single PDF bid package with embedded documents, including the completed SF-1442, bid guarantee, and limitations on subcontracting report, all submitted electronically by the deadline of April 15, 2026, with no hard copies accepted. The project's scope explicitly excludes roofing and window replacements, which were listed as optional line items but not exercised, ensuring the award remains strictly tied to the siding replacement scope.
