A multi-use, multi-level building currently under construction in Whitefish, Montana, will feature an elevator shaft manufactured from cross-laminated timber (CLT) rather than the traditional choice of concrete masonry units (CMUs). This elevator shaft—the first in the country to be made from CLT—will be 14 m (45 ft) tall on completion. The engineered wood technology—which will be a focus in the forthcoming February 2017 issue of The Construction Specifier—comprises several layers of lumber boards, stacked crosswise and bonded.
The doctrine of privity in the common law of contract protects architects and engineers from lawsuits by contractors by requiring that for one party to sue another, there must be a contract between them. However, recent developments in tort law have weakened this defense by providing a path for contractors to sue architects and engineers for financial losses resulting from negligent misinformation in the construction documents. An obvious way to prevent this is to have a clear, complete, correct, and concise set of construction documents and ensure the contractor’s bid likewise follows the Four Cs. The post-bid interview is the last opportunity to examine the contractor’s bid before a contract is signed.

Federal, state, and local specifiers continually seek affordable, durable, and aesthetically pleasing wall solutions to border bustling highways and adjacent neighborhoods. The principal purpose of these is typically to provide citizens with a visual barrier to the highway and sometimes to mitigate traffic noise. Today, highway barriers cover thousands of miles of federal roadways. When the walls first began to appear in the 1960s, they were modeled after wooden fences. Now, things have changed––according to the Federal Highway Administration (FHWA), almost half of the highway walls constructed in North America to date are made of concrete. That material meets many affordability, durability, and aesthetic specifications and preferences.
All over the United States, a hard truth is being uncovered—underneath carpet and vinyl tile in buildings everywhere, there lurks ugly concrete. With acceptance of exposed concrete floors on the rise, and remodeling continuing to dominate the construction market, plans to polish existing concrete subfloors are numerous. However, some slabs are simply not up to the challenge.
Observations of numerous building envelope failures in stucco (i.e. Portland cement plaster) indicate it may lack durability when correct installation practices are not performed. One of the most common problems is cracked stucco—and with the increasing trend of using the material as a cladding, the situation will likely get worse.
Clear-span aluminum structures and temporary steel buildings have advanced over the years. Knowing when to use them is a skill worth mastering for construction specifiers, procurement professionals, and facility managers. Familiarity with specific spaces, and knowing the assemblies’ framework of costs and benefits, may also help designers and specifiers incorporate them into their own sites and make optimal recommendations.
