A little forethought can prevent the potential overstress that occurs when deflection leads to rooftop ponding.
Every component manufacturing facility creates wood waste. Yet, it seems no two manufacturers take the same approach to collecting, disposing of or reusing the scrap byproduct. SBC Magazine would love to know the method you’ve adopted and why it works so well for your facility. Send your approach to editor@sbcmag.info.
Careful joint design can maintain fire resistance where walls meet roofs and floors.
U.S. Citizenship and Immigration Services (USCIS) is continuing efforts to strictly enforce regulations pertaining to Form I-9. USCIS states the I-9 “is used for verifying the identity and employment authorization of individuals hired for employment in the United States. All U.S. employers must ensure proper completion of Form I-9 for each individual they hire for employment in the United States.”
SBCA President Jack Dermer reflects on the past year and encourages members to get engaged as the organization embarks on a new year and new approach to quarterly meetings.
For decades, SBCA Jobsite Packages have helped component manufacturers (CMs) provide handling and installation guidance to their customers with every order. These pre-assembled packages of instruction documents, attached to truss deliveries in a zippered plastic bag, are now available in a digital format.
OSHA announced a heightened focus on cuts and amputation hazards after having received more than 2,600 reports of amputations nationwide in 2015. One CM discusses the benefits of taking a proactive approach, starting with proper machine guarding.
When Jim’s Apple Barn, the largest candy store in Minnesota, wanted to expand by way of adding a confection-filled planetarium to the end of a blazing yellow barn already bursting with sweets, it had a difficult time finding a truss company willing to take on the project. “We were the only ones that said yes,” recalled Trevor Ebinger, a member of the Manion Lumber & Truss sales staff. “It was quite an undertaking.”
Since FRTW studs are allowed in wall assemblies that are otherwise defined as non-combustible, building and truss designers often confront the question does a joint between the wall and the roof or floor assembly mean that those elements of the building also require noncombustible material, like FRTW? To answer this, we need to study the IBC
Minimizing wear and tear on your technology hardware is a significant step toward avoiding downtime and recovering quickly when problems occur.

At BCMC 2016, Brian Jones won the Lakeside Trailer vacation award: $5,000 towards a getaway of his choice.
This information is intended to help employers understand their responsibilities regarding the I-9, how to conduct a self-audit, and how to prepare and respond to an HSI audit.

Per ANSI/TPI 1, truss-to-truss connections are under the scope of work of the truss designer. All other connections between a truss and another structural member (i.e. a wall or foundation) are the responsibility of the building designer.
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.
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.
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.
ANSI/TPI 1 Chapter 3 covers quality standards for the manufacture of metal plate connected wood trusses. It requires the use of a manufacturing quality assurance procedure, and period auditing by an approved inspection agency where required by local jurisdiction.
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.
Integrating sprinkler systems into the open webbed configuration of metal plate connected wood trusses can be easy when following best practices. Truss construction can be manipulated with adjustments to panel lengths and web configurations to accommodate most special requirements. However, the Truss Designer needs to account for the additional weight of the sprinkler system and water. Additionally, construction loads encountered during installation need to be accounted for.
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.
Field splicing is a method used to connect two or more truss sections into a single component. There are many reasons why field splicing may be used. A component may be too large or deep to manufacture, fit on a truck, or handle. A design modification or retrofit may necessitate a field splice, whether due to a change in truss profile or loading. Whatever the reason, field splices are another way to allow for greater flexibility in truss manufacturing, shipping and installation.
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.
In the IECC, an air barrier is defined as “Material(s) assembled and joined together to provide a barrier to air leakage through the building envelope. An air barrier may be a single material or combination of materials.” The air barrier is an important part of integrated thermal and moisture control in a building. Many air barrier materials or strategies may be employed in a building that meet code requirements, however it is crucial to understand their interactions within the assembly.
Controlling sound transmission in buildings through wall, floor and ceiling assemblies is important for the comfort level and enjoyment of building occupants as they live, work and play in these buildings. Sound can come from a variety of sources: both internal to the building and environmental noise from the surrounding areas. The resources below explain how sound transmission is measured, and describe assemblies and other methods to limit noise transmission in buildings using components.
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.
I recently had a conversation with John Holland, head of IT for Clearspan Components, and he pointed out that if there’s one thing the component industry has a lot of, it’s problems
