What contract terms should control equipment substitutions and any resulting price changes after signing?

Answer

The contract should list exact equipment and prohibit substitutions without your prior written approval. If a substitution is allowed, it should require equal or better defined specifications, preserve compatibility and warranty protections, disclose any performance impact, and state how the price and schedule change.

Key points

  • Attach make, model, quantity, and material specifications to the signed agreement.
  • Define what counts as equivalent or better rather than using that phrase alone.
  • Require a written change order showing equipment, performance, warranty, price, and schedule effects.
  • Give you a right to reject a material substitution or cancel under defined conditions.

What it depends on

  • Equipment availability
  • System design and compatibility
  • Warranty and certification requirements
  • Change-order and cancellation provisions

Risks and trade-offs

  • Strict approval rights can create delays if supply changes occur.
  • A nominally higher-rated component may be less suitable or have different service support.
  • Unpriced substitutions can increase cost or reduce expected output.

Information you may need

  • Detailed equipment schedule
  • Substitution criteria
  • Price-adjustment formula
  • Approval, cancellation, and warranty provisions
