About this file
This is an Addendum and Unit Price Form issued by Whittington Architects Inc. for Grambling State University's reroofing project at Men's Memorial Gym in Grambling, Louisiana. The project involves removal and replacement of the existing modified bitumen roof system across approximately 21,726 square feet. The scope includes four line items: additional interply roofing membrane installation to eliminate ponding (500 square feet), replacement of deteriorated wood nailers and blocking with 300 series stainless steel fasteners at 16-inch on-center spacing (100 linear feet), extension of vent pipes above the roof to accommodate new insulation depth (8 units), and replacement of additional tectum tiles (100 square feet). Bids are due July 2, 2026 at 2:00 PM Central Standard Time with bid opening via Zoom at 2:05 PM the same day. Site visits may be scheduled by contacting Facilities at 318-274-6162. No pre-bid meeting is required.
The project is tax-exempt, and contractors must submit the attached Unit Price Form with their bid. The specification for roofing materials identifies U.S. Ply as a state-approved manufacturer and details specific Duraflex SBS membrane products for field plies, interply, granular flashing, and heat-fused applications, along with 901 Premium Modified Adhesive for cold adhesive application. All work is firm, net F.O.B. destination, and inclusive of labor, materials, equipment, tools, delivery, insurance, permitting, and applicable taxes. Bidders must demonstrate three years of prior business experience and hold all required Louisiana licenses and permits. A mandatory 5% bid bond is required, and the successful contractor must furnish a performance bond equal to 50% of the contract price. Contractors must maintain workers' compensation and commercial general liability insurance at $1,000,000 per occurrence minimum with Grambling State University named as additional insured. The project is funded through state appropriations, with payment terms of Net 30 following invoice acceptance, and liquidated damages assessed at $250 per calendar day for delays beyond substantial completion.
