TAB Journal Spring 2018 - 3
Asking detailed questions during the bidding process
requires additional effort and the knowledge of how
systems function and operate under different parameters.
Performing sound readings in a large kid's restaurant
that is mainly an indoor playground really should not be
required. Regardless, TAB agencies should be reading the
required applicable specifications and incorporating these
requirements into their bids. Guessing on bid day should
be the last resort, because is unfair to the owner due to the
added expense. Nevertheless, always include a detailed
scope with the bid.
In a likewise scenario, many commissioning specifications
inform the bidder that commissioning is a requirement
on a project but limited project-specific requirements
are usually provided. This is not the fault of the
commissioning agent because like the design engineer,
they are not being provided the time to address the
requirements that need to be performed. Providing the

pre-functional and functional performance test equipment
and scope of test should never be provided after a bid
unless an allowance is provided for the commissioning
process. After-the-fact specification revisions almost
always require additional time, and this extra testing
should not be expected to be absorbed by the TAB Agency
because because guesswork was required. Changes that
add to the price after the fact should be addressed.
In closing, the HVAC industry needs to slow down and
get back to the attention to detail as it had in the past.
The craftsmanship in the field also needs to change. Less
time is being provided to complete these projects but more
deficiency reports are being issued than ever. TAB agencies
also need to be included in the design review process to
provide a separate set of eyes and help designers with their
specification when needed. This cannot happen when time
requirements drive a project. It takes time to do it right.
