Question

Darcy has selected trusses for the roof framing of her home. The contractor has just received the shipment with the trusses, and he tells her that he won’t be able to install them. Which reason for this hiccup makes the MOST sense?

Because Darcy’s home plans include an attic.


Because trusses are very difficult to install.


Because the trusses will put the project over budget.


Because trusses aren’t used to frame roofs.

Answer 1

reason that makes the MOST sense for the contractor's inability to install the trusses for Darcy's home is "Because Darcy's home plans include an attic." Trusses are engineered to support specific loads and are designed to work in conjunction with other elements of the roof structure, such as the sheathing, to distribute the loads to the walls and foundation. If the home plans include an attic, the trusses would need to be designed to accommodate the additional load of the attic floor and any storage or other activities that might take place in the attic. If the trusses were not designed for this additional load, they would not be suitable for use in Darcy's home. Therefore, the contractor may not be able to install the trusses, and a different type of roof framing may need to be selected or the trusses may need to be re-engineered to accommodate the attic. The other reasons mentioned in the options, such as trusses being difficult to install or not being used to frame roofs, are not valid reasons for the hiccup
