Door hardware specifications can be confusing and tedious. Just the thought of having to recall door hardware terminology, code requirements, and best practices is overwhelming. Then, transferring that knowledge to work when designing commercial or institutional facilities with hundreds to thousands of openings, each including five to 10 pieces of hardware, seems like a monumental task. This reference guide explaining common terminology and hardware will help make the process a little less daunting.
Sometimes combining dissimilar things can be surprisingly beneficial (e.g. chocolate and peanut butter). In other instances, mixing different items can have adverse results, and may need expert guidance.
Nithya Caleb, the editor of The Construction Specifier, interviews independent specifications consultant Vivian E. Volz, RA, CSI, CCCS, AIA, LEED AP, about the delegated design and design assist processes.
Nithya Caleb, the editor of The Construction Specifier, interviews Corey Zussman, director of quality management, Pepper Construction, about constructability issues that can arise on a jobsite, and how to avoid them. Here is an extract.
The lack of standardized terminology results in bids, including fully refined, ground, and polished concrete floors as well as surface-applied sealers or coatings. Using contractor terminology to build a means and methods specification always backfires, and the nature of the language leaves the design firm and owner at risk for poor outcomes.
