Jobsite Documents

Question: 

It is critical that permanent top chord bracing is supplied by proper nailing of the valley truss bottom chords to the carrying truss top chords, through purlins or properly installed rated roof sheathing. If the sheathing is not carried through under the valley framing, then the permanent top chord bracing must be supplied in another manner.

Question: 

When you’re selling trusses through a lumberyard and the contractor calls to say that the “trusses don't fit correctly,” who has the ultimate responsibility for the trusses? I argue that the lumberyard is responsible since we have provided them with all the information on how the job was designed, even though they may or may not have passed this information on to the contractor.

Question: 

I am looking for strongback bracing requirements for a 12 in. deep residential floor system with trusses in lengths up to 19 ft. Can the strongback bracing end at a truss without tying into an end wall? For instance, can three trusses of a type be tied together by strongbacks, then the next series of different trusses be tied together without having to be tied back to the previous type of trusses?

Question: 

We have been specifying laminated veneer lumber (LVL) beams for some time now. The plans usually state, “Beam to be engineered and supplied by truss manufacturer.” What kind of liability issues do I need to watch out for?

In order to promote the safe installation of building components including trusses, manufacturers send out a Jobsite Package to the construction site with the truss delivery. These Jobsite Packages include the Truss Submittal Package. The Truss Submittal Package includes the information that if required will be submitted to the Contractor/Building Designer, who if required will submit it to the local building official.

Truss placement diagrams (TPDs) may be one of the more misunderstood documents in our industry. 

Woodhaven designed and built the roof and floor trusses for the Spruce Street Shul. Woodhaven also supplied the lumber and hardware for the project.

The purpose of this article series is to identify truss-related structural issues sometimes missed due to the day-in and day-out demands of truss design/production and the fragmented building design review and approval process. This series will explore issues in the building market that are not normally focused upon, and provide recommended best-practice guidance.

  • CMs deal with customers with a wide range of skill sets, including those who have drawn their house plans on a McDonald’s paper napkin. I wish I were making this up!
  • While CMs are not responsible for ensuring that customers brace jobs correctly, they can provide BCSI documents to help customers build a better building and stay safe.
  • The BCSI book and B-Series Summary Sheets are a CM's saving grace, especially if the customer plans to install the trusses on their own or not hire an engineer of record.
  • Sending a Jobsite Package with each truss delivery is a good way to share safe installation and bracing recommendations with framers.
  • In the near future, SBCA is committed using SBCRI testing to optimize BCSI guidelines.
  • We hope to change bracing design by combining temporary and permanent bracing into one step.
  • Information about installation tolerances can be found in the B1 Summary Sheet.
