Trusses are engineered components that will perform as intended if installed correctly. However, those who are installing trusses are not always adept in deciphering truss layout drawings.
A vast majority of construction projects end up hiding trusses behind some type of sheathing. However, that isn’t always the case. In a brewery in Sauk City, Wisconsin, the design-build project called for a variety of diverse building elements, including exposed trusses.
For over 30 years Bruce Jones has looked for continuous improvement in producing wall panels, often being the preferred component manufacturer (CM) framers want to do business with. His success is due largely to his willingness to educate his customers to use the product he supplies to their best benefit.
“From a framer’s point of view, the hardest part of wall panelization is not being involved early enough in the process.” says Ken Shifflett owner of Ace Carpentry in Manassas, Virginia.
“People don’t remember what you say, they remember how you make them feel,” asserts Margaret Welliver, human resources manager at Shelter Systems in Westminster, Maryland.
Trusses can be used in nearly any type of structure. A mosque built in Granger, Iowa, showcases a unique use of roof trusses to construct a large dome, a common feature of any mosque.
Shear blocking is an effective way to provide lateral support at raised heel truss ends and transfer shear forces to the foundation of a building. In fact, in many cases it is required by both the 2018 IBC and IRC codes. Component manufacturers (CMs) are in a perfect position to save framers, GCs, and (ultimately) project owners time, money, and labor through more efficient solutions.
Automatic sprinkler systems installed in commercial, multifamily, and residential construction provide improved fire protections to the building, its contents, and its occupants. Trusses are often used in the roofs and floors of many of these buildings and the openness provided by the webs make trusses especially compatible with mechanical, electrical, and plumbing systems, including sprinklers.
Timber harvested from federal lands is one source of the billions of board feet of softwood lumber the U.S. produces annually. Recently, this source has been gradually increasing year by year due to shifts in policy and U.S. Forest Service management practices. Harvest totals are projected to continue their upward trend, and if that trend sustains, increased supply can potentially decrease lumber volatility. In 2017, 2.9 billion board feet of timber were harvested with a 2018 goal of 3.4 billion growing to 4 billion in 2020.
