Best practices for addressing truss alterations by plumbers

According to an online survey of component manufacturers (CMs), 96 percent of respondents indicated they have had a plumber damage or modify their products after installation.

Partition separation is not typically caused by truss uplift.

This article will briefly explore how these calls can impact a CM’s bottom line and a few ways in which CMs can proactively work with tradespeople to avoid such issues. Truss repairs can very easily turn a profitable job into a money losing project. The cost incurred with this type of repair goes beyond the price of the materials. Costs for determining the issue for repair, designing the repair, and implementing a repair solution shouldn’t get lost in your accounting books. 

The tables are intended as a practical tool to assist contractors in the selection of footing widths and the determination of the quantity of wood studs required for supporting the end reactions of beams, girders, and/or headers. 

Question: 

Occasionally we deal with truss failures due to impact and or crushing forces such as trees falling onto roof structures. At what point can the truss no longer be repaired? Also, what should an adjuster look for when determining repair-ability? Or should a storm adjuster basically punt and call a consultant for every truss failure?

Question: 

I am a professional engineer looking for information concerning the failure of metal plate connected wood trusses and methods of repair. I am looking for this information with regard to developing recommendations for the repair of truss systems in the floor structures of two-story multi-family dwellings. I see frequent failure of truss systems of this type in both in bending and due to catastrophic failure at the gussets.

Question: 

Can I put a wood deck (1/2 in. plywood) on top of the bottom chord of a 26 foot span truss 24 inches on center?

Question: 

Our home caught fire last month and burned partly through a tongue and groove ceiling to the trusses. Some are charred. Our contractor did a moisture meter test. An engineer for the insurance company said the trusses were only smoke damaged & the moisture meter test is invalid (it can be set to read anything). I found one article on charred trusses, but it’s pretty vague. We do not feel safe with the insurance engineer’s assessment because some of the trusses are obviously charred. We hired an engineer who agreed with us.
