What is the missing piece after the design contract has been awarded and the basis of design is kicking off the design phase of the project?

When I first started in the HVAC industry working in a design consulting engineering firm, I came to accept that the HVAC sequence of operation and its associated contract specification, Automatic Temperature Controls (ATC), were provided by an ATC sales engineer.

Planning ahead will help you reach systems for inspection and maintenance.

Last month, I opened a discussion on how I have enjoyed integrated project delivery (IPD) and design-build (D-B) projects over the years and how I have been fortunate to learn from other team members as I shaped my “full team participation” (FTP) process.

Over the years of designing and building HVAC infrastructure, I’ve been fortunate to be able to complete the projects via integrated project delivery (IPD) and design-build (D-B), in addition to design-bid-build (DBB) and construction management (CM).

Hydraulic modeling is seldom used in the day-to-day design of closed-loop or open-loop heating and cooling systems.

Engineers who pull out the 2015 ASHRAE Handbook HVAC Applications or 2016 HVAC System and Equipment Handbook will not find the topic of temporary HVAC systems.

Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.

With last month’s publication, Engineered Systems magazine and I completed the 25th year of publishing this column.
