About this file
This is a specification document for metal roof and wall panels prepared by the Fontana Unified School District, a K-12 public school district in San Bernardino County, California serving approximately 32,000 students across 45 school sites. The specification details requirements for preformed roof and wall panels, accessories, and related materials for installation on portable buildings. The district is soliciting sealed bids for portable building maintenance and repairs under Bid No. 25/26-0045 through its procurement portal, with bids due no later than 2:00 pm on Tuesday, May 26, 2026. The resulting contract will have an initial term of four additional years, with a total potential duration not to exceed five years. The district estimates annual costs for portable building maintenance and repairs may reach up to $1,500,000.00, though this figure is provided for informational purposes only and does not constitute a binding commitment.
The specification establishes quality assurance standards requiring compliance with AISC, AISI, ASTM, and SMACNA standards, with installers required to have a minimum of two years of experience and manufacturer certification. Acceptable panel materials include galvanized steel, galvalume-coated steel, and aluminum, with manufacturers specifically listed including Berridge Manufacturing Company, IMETCO, AEP-Span, Peterson Aluminum Corporation, Una-Clad Copper Sales, and McElroy Metal. The specification requires a 20-year material warranty from the manufacturer and a 5-year labor warranty from the installer. Installation must comply with manufacturer instructions, with panels installed plumb, level, and straight without distortion, allowing for expansion and contraction. All panels must be delivered undamaged and stored above ground on skidded platforms under waterproof covering with proper ventilation.
