Greenhouse Roof Replacement and Rail Replacement

This government solicitation, 1232SA26Q0438, issued by the USDA ARS, seeks proposals for a Greenhouse Roof Replacement and Rail Replacement project. This is a total small business set-aside with NAICS code 236220. Key dates include a mandatory site visit on 4/23/26, and RFI submissions by 4/29/26. Offers are due by 05/08/2026, 0630 AM CST, and require a bid guarantee. The contract has a 10-month performance period, split into two phases: roof replacement after Notice to Proceed, and rail replacement starting December 2026. The project location is the USDA Sugarcane Research Site in Schriever, LA. The solicitation outlines various FAR and AGAR clauses, including those for commercial construction, anti-discrimination, and progress payments. Contractors must adhere to strict requirements for materials, site management, safety (OSHA), and personnel. Payments are contingent on compliance with certified progress payment requests, and specific conditions apply to stored materials. The project will involve Construction Management oversight by a USDA Third-party A&E firm.

This Statement of Work outlines two critical construction projects at the USDA Sugarcane Research Site in Houma, LA, scheduled for completion by March 2027. Scope A involves the emergency replacement of the existing Crossing Greenhouse Roof, originally built in 2007. This includes removing old Thermolite panels and spline gaskets, cleaning frames, and installing new 16mm double-skinned acrylic sheets, along with replacing panels in ridge and eve vents. Damaged south-side ridge vent rods will be replaced and aligned. A mandatory water leak test with government oversight and a one-year leak-free installation warranty are required. Scope B focuses on replacing the Photoperiod Rails, which are corroded by fertilizer. This involves removing existing steel rails, creating new concrete slots, and installing continuous FRP extrusions and hollow fiberglass rails filled with non-shrink epoxy grout. Both scopes require submittals for government approval, adherence to Davis-Bacon wages, and the provision of bid bonds, bid guarantees, and performance bonds.

The document outlines a project for repairing and installing a new fiberglass track rail at the USDA Agricultural Research Service Sugarcane Research Laboratory in Houma, Louisiana. The project, titled “PHOTOMETRIC BLDG RAIL REPAIR,” involves removing existing concrete and angle iron, grinding the trench bottom, and installing a 60-foot structural fiberglass track rail with a minimum 30,000 PSI compressive strength. Key requirements include using a high-strength epoxy grout system, such as SIKAGROUT 713 or SIKADUR-42, for primary rail attachment and support, ensuring the rail is fully supported without voids. Elastomeric rail grout with vibration-dampening characteristics, like Stonhard Elastomeric Grout, is specified. Exposed top joints are to be sealed with a compatible polyurethane elastomeric sealant such as SIKAFLEX NP 1 or SIKAFLEX SL 1. The installation process emphasizes proper surface preparation, alignment, continuous grout placement, and post-grout cure sealing of joints. The existing research cart wheel has an approximate weight of 3,000 lbs, with plants adding 600 lbs, resulting in a total approximate weight of 900 lbs per wheel.

The document outlines specifications for Fiberglass Reinforced Polymer (FRP) profiles for the Houma Rail Replacement project, focusing on two items: a Hollow Custom rail profile (Item 001) and a Fiberglass Trough Profile (Item 002). Both require polyester resin and must support a 900lb wheel load over a 12-inch span. Key details include material dimensions, tooling costs, and lead times, with contractors responsible for verifying specific lengths and lead times. The system description details an assembly of FRP structural members, epoxy grout infill, a concrete slab support, and a flexible adhesive/sealant layer. Structural performance analysis shows the FRP tube and epoxy grout operating well within their ultimate and compressive strengths, respectively, under anticipated wheel loading, indicating a substantial safety margin. Environmental performance in Houma, Louisiana's humid, coastal climate highlights the FRP/grout system's corrosion resistance and stability against moisture and temperature fluctuations. The system's design minimizes fatigue damage and local buckling, ensuring long-term durability.

This amendment (1232SA26Q0438-0001) to a solicitation issued by USDA ARS Acquisition and Property D, located at 5601 Sunnyside Avenue, Beltsville MD, 20705, serves to provide responses to Requests for Information (RFIs) that were generated from a recent site visit. The amendment, dated 04/08/2026, modifies the original solicitation dated 04/29/2026. Offerors must acknowledge receipt of this amendment by completing and returning copies of the amendment, acknowledging receipt on each offer copy, or by separate communication, ensuring it is received prior to the specified offer receipt hour and date to avoid rejection of their offer. All other terms and conditions of the original solicitation remain unchanged.

The RFI Responses for USDA's 1232SA26Q0438 Greenhouse Roof Replacement clarify several key aspects of the project. USDA will not accept stainless steel rails due to the corrosive nature of fertilizers. The project's period of performance (POP) will be adjusted to accommodate a six-week lead time for roof panels. Warranty requirements include one year after installation and the manufacturer's warranty on materials. A single individual can serve as Superintendent, Quality Control Manager, and SSHO, provided all requirements are met; however, a second qualified SSHO is required when work is conducted at 15 feet or higher. While no roof survey was performed, the scope of work includes adjusting and straightening 12 bent ridge frames. Any additional damaged ridge vents noted during the work will be reported to the Contract Officer and addressed under a future contract.

The document outlines the design and product specifications for a greenhouse and natural ventilation system for the USDA Sugarcane Research Laboratory in Houma, Louisiana. It includes detailed drawings (GM-310) for the crossing facility, maturation facility, carts room, and link, focusing on ridge and side vent openings, drive mechanisms, and structural elements. The project emphasizes the use of DEGLAS High Impact Acrylic Glazing for its superior light transmission, energy efficiency, durability, and a 30-year no-yellowing warranty. Additionally, Thermolite insulated spandrel panels, known for their energy-saving properties and fire resistance, are specified for curtain wall applications. The document also includes installation guidelines for both glazing and spandrel panels, ensuring adherence to design concepts and construction standards.

This document, General Decision Number LA20260046, outlines prevailing wage rates for building construction projects in Terrebonne County, Louisiana, excluding single-family homes and apartments up to four stories. It lists specific wage and fringe benefit rates for various crafts like electricians, plumbers, ironworkers, and laborers, along with their effective dates. The document also details federal regulations, including Executive Order 13706, which mandates paid sick leave for federal contractors, and Executive Order 13658, which sets minimum wage requirements. It explains the identifiers for union, weighted union average, and survey-based wage rates, and provides a clear process for appealing wage determinations, directing inquiries to the U.S. Department of Labor's Wage and Hour Division and the Administrative Review Board.

Amendment 0002 to solicitation 1232SA26Q0438 updates the specification for roofing material and revises key dates. The bid due date has been changed from May 8, 2026, to May 14, 2026, and the distribution date from April 29, 2026, to May 8, 2026. This amendment ensures that all terms and conditions of the original solicitation, as previously modified, remain in effect, except for these specific changes. Offerors must acknowledge receipt of this amendment by one of the specified methods to ensure their offers are considered.
