Attachment 9 - Substitution Request.pdf

This document is a Substitution Request form for the Replace Headhouse Roof Plant Genetics Research Unit project. The form is submitted by DMI (Dimensional Metals, Inc.) for a DL2016 Standing Seam Metal Roof Panel as a proposed substitution. The proposed panel is a DOUBLE-LOCK DL20 structural panel that is mechanically seamed during installation, with applications including low to high slope roofing, vertical fascia, equipment screens, mansards, and wall panels. The panel can be installed on tapered and curved roof areas and offers advantages such as factory-applied non-curing sealant, SMACNA design compatibility, mechanical seaming, expansion clips, continuous roll-formed lengths, and total system warranties. The panel has been performance tested under various ASTM standards including wind uplift, static air pressure, water penetration, and air leakage tests.

The substitution request includes certification that the proposed panel has been fully investigated, is equal or superior to the specified product, will have the same warranty, maintains project schedule, has no adverse effects on other trades, and will not impact dimensions or functional clearances. The panel is available in multiple colors through DMI's DynaClad PVDF color chart, with options for different substrate materials, panel widths, clips, and finishes. The document is part of a solicitation for replacing the headhouse roof at the USDA Agricultural Research Service's Plant Genetics Research Unit in Columbia, MO, which is set aside for small businesses with a project magnitude between $100,000 and $250,000 and a performance period of 85 days after notice to proceed.
