Plans
and specifications are made after the concept is set with the owner.
An architect will make up a set of drawings, and a structural engineer
will do the same. Together they come up with approximate sizes of
the truss members along with all the other drawings.
The drawings
we receive are in one of two stages: Either they are in a preliminary
stage, and the architect will issue a set of drawings intended for
pricing only; or the owner will employ a general contractor, along
with the architect and engineer, and will issue a complete set of
drawings with specifications for construction. We use a full set of
plans to determine the amount of material, labor and truss engineering
are needed and give the parties involved a bid.
The more
complete the drawings and specifications are, the more accurate our
bid will be. We will often work with architects to better specify
heavy timber trusses for manufacturing and cost savings.
