From Seminars to Articles

Many features contributed to The Construction Specifier begin with a simple query e-mail or phone call—a specifier, architect, engineer, professor, or product rep has an idea for a story and wants to share it with our audience. In many other instances, however, we go searching for features. The editorial team goes out to established or emerging experts, proposing they write on technical topics that are either ‘hot’ or still under the radar. Continue reading

Inspect the Substrate!

Our March 2013 article, “Using Pre-cured Sealants in Construction Applications,” written by Jason Bakus, resulted in a letter to the editor from Gerald “Jerry” Zakim, CSI Emeritus.

Zakim, who has written for The Construction Specifier’s Failures column, e-mailed his comments:

With interest, I read Jason Bakus’ March article and its advocacy for the material’s use adhered to residual sealant. Since it is a given, in all circumstances, that surfaces must be clean, dry, free of foreign matter, and sound to receive any materials applied, I was disappointed there was no mention of the importance of inspecting the surface. This needs to be done to determine whether further preparation has to be made to ensure the ability of the old sealant/adhesive to hold/adhere the pre-cured sealant under the stress and strain of the movement that must take place.

Wind loads guide released

ASCE
The American Society of Civil Engineers (ASCE) has released a new edition of Wind Loads, a guide focused on ASCE/SEI 7-10, Minimum Design Loads for Buildings and Other Structures. Written by Kishor C. Mehta and William L. Coulbourne, the revised text now includes six chapters dedicated to wind load provisions, rather than only one for both residential and commercial building. Aimed at an audience of structural engineers, it includes simplified calculation methods and cladding guidelines. The guide provides an overview of design features, wind map information, 14 case study examples, and frequently asked questions. Copies are available at www.asce.org.

UFAD technology resource published

ASHRAE
Published by American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE), UFAD Guide: Design, Construction and Operation of Underfloor Air Distribution (UFAD) Systems provides an overview of the increasingly popular technology. The book also includes design experiences from practicing UFAD users, studies, and additional manufacturer’s information. The system integrates a building’s heating and air-conditioning and uses less energy than ducted systems due to its decreased operating pressures. UFAD’s popularity is increasing due to space-conditioning concerns in North America, so this book also outlines the differences between it and traditional technologies.
