Construction

  • The 2012 IRC does not provide sufficient details on how to connect wood trusses to braced wall panels.
  • SBCA has developed a couple of details and will continue to develop standard details that provide code-compliant connections between roof/floor trusses and braced wall panels.
  • Component manufacturers can provide framers with specialty or standardized blocking panel products to reduce the time needed to install the blocking between trusses for these connections.

 

  • Successfully constructing a building today takes effective communication and collaboration between building architects, structural designers, component manufacturers and framing labor contractors.
  • NFC’s first focus is to develop a national safety program for framing contractors.
  • NFC also plans to develop a scope of work document outlining standard responsibilities for framers and subcontractors.

When designed and installed correctly, components can greatly reduce the time and materials required to frame a structure. 

Last summer, Superstorm Sandy caused an estimated $65 billion worth of damage in the U.S., a total surpassed only by Hurricane Katrina in American history. Sandy was the largest hurricane on record to hit the Atlantic Coast, at over 1,100 miles in diameter. So while it hit the New Jersey shores the hardest, according to the National Oceanic and Atmospheric Administration, its disastrous effects were felt as far inland as Wisconsin and Michigan.

While the chaos and destruction wrought by this powerful natural force is sobering, it’s hard not to simultaneously focus on the positive stories that came out of such events. One such story is that of Cussewago Truss LLC in Cambridge Springs, PA. It’s a tale of the marvels of wood, the value of engineering and the fruits of a well-executed plan.

Ever have one of those component jobs where everything went exactly to plan, only to have a hiccup at the last moment? 

By creating national standards, based on field-tested best practices, the National Framers Council (NFC) will not only help improve the safety of each worker on the jobsite, it will aid in reducing ambiguity in everything from OSHA jobsite inspections to residential fall protection. 

  • Use of galvanized box nails may result in shear walls with a shear capacity significantly below the nominal unit shear capacities given in SDPWS.
  • Thus, the majority of WSP shear walls have a shear capacity with a high degree of design value variability. This may have unintended consequences that are unknown and unappreciated by the professional engineering and/or building design community.
  • Once SBCA and SBCRI were certain their testing and engineering analysis was consistent and repeatable, they were persistent in bringing all WSP shear wall performance issues to the attention of APA, AWC, ICC-ES and ICC.  
  • The most effective way to avoid recurrent issues with component installation is to give an SBCA Jobsite Package to the general contractor and framing crew on every job.
  • Simply having your driver drop the Jobsite Package off with the component package at the jobsite isn’t enough.
  • Anytime you work with a GC or an inexperienced crew for the first time, consider visiting with them ahead of delivery and walk them through the information in the jobsite package.
  • The National Framers Council (NFC) was formed as a council of SBCA to give framers a national organization that will focus on best practices in jobsite safety and building material installation.
  • NFC’s goal is for each framer to leave the jobsite every day in the same health as when they arrived.
  • The more framers and CMs interact, the more we will be able to identify framing and component implementation issues in the field and find solutions where both industries win.
