Deferred testing is performing FPT after substantial completion. Whereas systems performance testing should occur prior to the owner accepting the systems from the contractors, there are some instances where testing at the end of construction is either impractical or not meaningful.
In my October and November columns, I explored the complexities associated with motivating contractors to install, start up, and test new building systems as required to have the commissioning testing and demonstration be successful the first time. If there is an incentive for deficiency-free test results, the commissioning professional needs to be wary of the contractors wanting to stop and “fix” deficiencies during the testing process.
In September's column, we focused on the need to motivate project teams to correct systems performance deficiencies in a timely fashion follow-ing unsuccessful FPTs. This month, I'd like to explore the question of why there are unsuccessful FPTs in the first place.
My May, 2006 column introduced the concept of decommissioning as a process for thoughtfully and systematically preparing for partial renovation of an existing building - something that happens more frequently than the construction of new buildings.
As with last month, I'd like to introduce a new commissioning term, which isn't exactly mainstream in the commercial and institutional building industry. This time, the word of the month is decommissioning. Although a rigorous process of decommissioning has been standard operating procedure for a number of years at the Pentagon Renovation Program, I have otherwise only heard of it with respect to nuclear power plants, naval vessels, and some industrial installations.
The commissioning lexicon currently includes terms such as recommissioning, retro-commissioning, and continuous commissioning. This month, I'd like to explore a concept that may not be new, but which I believe is an integral part of commissioning a building renovation project. By giving it a name, I'm hoping it may be more likely to become common practice. I'd like to dub it pre-commissioning.
The high-profile equipment involves an efficient, resilient trigeneration plant to provide heating, cooling, and power service. However, UConn’s most critical asset may be its forward-thinking, campus-wide energy strategy. Read more stories in June Issue 2017.
