The potential for extensive damage during a fire event is greatest when a building is under construction because it is largely unprotected.
General Contractor Topical Library
SBCA generates a large volume of timely, applicable information to its members and the industry at large on a wide variety of topics. Recognizing it can sometimes be difficult to locate a specific resource among this volume of content, we’ve created a topical library on the most prevalent subjects of interest to component manufacturers today. This topical library pulls together the most relevant articles, news items, best practices and other online resources on each topic.
The Occupational Safety and Health Administration (OSHA) regulates fall protection procedures for residential construction jobsites under 29 CFR 1926 Subpart M. These statutes provide minimum requirements for the mitigation of fall risks during erection.
SBCA supports universal building installation of sprinklers for all types of construction, provided they are cost effective and do not create a competitive advantage for one structural element over another. When it comes to properly locating and designing sprinklers within a building, the IBC and IRC reference NFPA 13, 13D, and 13R (depending on the type of building). The resources below will assist the designer in understanding and implementing sprinkler systems in accordance with applicable building codes and referenced fire protection standards.
Fire Retardant Treated Wood (FRTW) products are permitted by code in certain situations where a fire resistance rating is required.
Framing the American Dream data suggests that installing floor trusses requires less framer skill and experience, results in a floor that requires less bearing locations and more effectively accommodates HVAC, plumbing and electrical infrastructure. SBCA, with the help of its members, has developed a wide variety of resources and tools to help component manufacturers design, build and deliver high quality floor trusses to their customers.
No matter the species, component manufacturers (CMs) purchase and rely on the accuracy and reliability of many different lumber design properties, including: bending (Fb); shear parallel to grain (Fv), compression perpendicular to grain (Fc^), compression parallel to grain (Fc), tension parallel to grain (Ft), and modulus of elasticity (E and Emin).
According to industry surveys, lumber constitutes roughly 40 percent of the cost of manufacturing a structural component. As a consequence, an adequate supply of North American softwood lumber is vital to the success of component manufacturers. Insect infestations and wildfires (natural forces), as well as protectionist trade actions and logging restrictions (man-made forces) can have a significant impact on the available supply of lumber. Forces that constrain supply at a time when demand increases (i.e. growth in residential construction), can have a severely negative impact on the stability of lumber costs.
Mold can be found almost anywhere and can grow on virtually any substance, provided moisture is present. Mold differs from decay in that mold does not cause a decrease in the strength properties of lumber, however it can cause discoloration or odors on the lumber. The resources below will provide CM’s and builders with a better understanding of how mold can affect components, legal issues surrounding mold, as well as steps that can be taken to mitigate mold growth.
Permanent bracing and continuous lateral restraint is sometimes required within trussed systems to provide long-term stability and/or lateral force resistance. Individual structural components are designed to withstand loading conditions within a particular plane, so there are instances where the building designer may specify the use of permanent building stability bracing. The resources below provide guidance on issues pertaining to the design and application of permanent restraint/bracing.
Framing the American Dream data suggests that installing roof trusses completes the task of framing a building’s roof in less time, requires less framer skill and experience and ultimately results in a roof that enables more open and flexible floor plans. SBCA, with the help of its members, has developed a wide variety of resources and tools to help component manufacturers design, build and deliver high quality roof trusses to their customers.
During component installation, temporary restraint/bracing provides stability against unintended movement or loading prior to the application of exterior sheathing. Structural components are designed to withstand loading conditions over the course of the life of the structure under normal use conditions. However, during construction, insufficient temporary restraint/bracing may lead instability and even collapse under certain conditions such as high winds or seismic events. The resources below provide guidance on issues pertaining to the application of temporary restraint/bracing.
A truss may need to be modified or repaired due to accidental damage, holes or notches made by trades, errors in design or manufacturing, or a change requested by the customer. Trusses are typically designed for a specific application. Therefore, truss repairs or modifications must be analyzed on a case by case basis. The truss repair or modification must result in a truss that is able to safely carry all intended loads. Depending on the extent of damage, some trusses cannot be repaired and must be replaced. Below find more information about truss repairs and modifications.
Framing the American Dream data suggests that installing wall panels completes the task of framing a building’s walls in less time, requires less framer skill and experience and ultimately results in a more reliable building envelope. SBCA, with the help of its members, has developed a wide variety of resources and tools to help component manufacturers design, build and deliver high quality wall panels to their customers.
