A contractor discovers that the mechanical specifications require a specific brand of HVAC equipment, but an equal substitute is available at 30% less cost. What should the contractor do?
Correct Answer
B) Submit a formal substitution request to the architect/engineer
Any substitution of specified materials or equipment must go through the formal substitution request process with the design professional for approval before proceeding.
Why This Is the Correct Answer
Option B is correct because construction contracts and professional standards require that any substitution of specified materials or equipment must go through a formal approval process. The architect or engineer who created the specifications has the authority to evaluate whether a proposed substitute meets the design requirements, performance criteria, and project standards. Making substitutions without proper approval can lead to liability issues, warranty problems, and potential rejection of the work. The formal substitution request process protects all parties and ensures the substitute meets project requirements.
Why the Other Options Are Wrong
Option A: Install the specified equipment as required
Making the substitution without approval violates the contract terms and professional standards, regardless of cost savings. The contractor does not have the authority to unilaterally change specified equipment, and doing so could result in breach of contract, liability for performance issues, and potential requirement to remove and replace the equipment.
Option C: Make the substitution to save the owner money
Contacting the manufacturer for a better price doesn't address the substitution issue and may not result in the same cost savings. This approach also doesn't follow the proper protocol for handling potential substitutions in construction projects.
