Identify the walking-surface product.
Ask for the selected board line and intended use. Keep that description attached to the actual surface component in the proposal.
Decks · DuPont, Washington
Decks in DuPont described as composite should identify which components use that material. Ask the provider to distinguish the walking-surface boards from the structural framing supporting them.
Evergreen Home Pro helps you read the proposed deck’s material schedule. Keep the surface, framing and other components individually identifiable rather than assuming one material description covers the entire structure.

Deck construction
Trex states that its decking is not a structural product. Have the responsible designer identify the actual framing materials and assessed support arrangement separately from the selected walking-surface boards.
Ask for the selected board line and intended use. Keep that description attached to the actual surface component in the proposal.
Have the qualified provider identify the framing and its role in the complete deck. A surface-board brand should not substitute for a framing description.
Ask whether an alternate product changes the surface, the framing or another part. Have the responsible designer assess the specific substitution and applicable instructions.
Before work begins
Ask DuPont Building Services which plans and review apply to the proposed deck. Describe the complete structure, location and intended construction.
Have the applicant include the assessed supporting arrangement with the selected surface materials. The complete design needs review beyond a decking product’s marketing description.
Ask the provider to identify the actual material for each component.
Have the responsible designer check the product’s intended use and the actual design.
Keep surface materials, framing and other components clear enough to understand which work and products are included.
Tell us about the desired surface and any framing arrangement already proposed.
