Designing Plaza Hardscapes
Frequently constructed over occupied spaces, outdoor plazas break up the massing of neighboring buildings with landscape treatments and traffic pathways. How can one design for the various structural and waterproofing needs? Standing on a mattress can help.
Impactable Dock Doors Help Increase Safety in Warehouses
For industrial applications, loading docks require carefully chosen openings. When it comes to specifying the doors, important considerations include not only efficiency, durability, and safety, but also the impact of high winds.

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

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
