TRANSCRIPT
The Scherer Brothers Lumber Company is a building materials
supplier and manufacturer. Scherer Brothers manufacture all of the
trusses that were used in the Landschute residence.
Step 1: PlanThe process of truss integration into the building begins with the architect or a
member of the office. A PDF file containing the building plans of the residence
is sent via email to The Scherer Brothers planning team. The planning team
then goes over these documents to decide how the trusses should be laid out.
Each building is different, and each of The Scherer Brothers planners will lay
out a job differently.
Step 2: DesignAfter the job has been laid out the plans now containing the truss positions is
sent to The Scherer Brothers design team. Here a member of the design team
will design each individual truss. For our residence this process took only a
few hours. Once the trusses have all been designed the completed building
plans, now with all of the trusses are sent to St. Louis where they are approved
by an engineer. Once approved the plans are sent back containing a stamp of
approval. This stamp of approval is not required by law, but it does give an
added sense of security to the client. From here the plans are sent electronical-
ly to the computers on the manufacture floor. Workers on this floor complete
the actual building of the truss, with the assistance of several pieces of
machinery that are run by computers.

Step 3: BuildThe truss begins as raw lumber in the Scherer Brothers lumber yard. A work-
er receives the ‘shopping list’ of pieces needed for a job and begins collecting
all necessary pieces, stacking them on a conveyor belt. The conveyor belt is
connected to a large saw which is hooked up to a computer. This saw perfectly
cuts all pieces of wood required for the job.
Workers then take these pieces to the assembly tables. The assembly tables
have lasers hanging from the ceiling above them, which point down to the
table surface and outline the entire truss. A worker then positions and tightens
nuts at all corners and connections of the truss members that are outlined.
This allows for fast and efficient assembly of the truss. Once this is done three
people work together placing all of the truss members on the table in their
designated spots.
In order to securely join all pieces of wood together a special patented steel
tooth connection plate is placed at each meeting of truss members. Each plate
is hammered in by hand slightly to hold it in place before a large steamroller
sweeps over the entire truss, securely fastening all pieces of the truss togeth-
er. The completed truss is now rolled off of the assembly table and grouped
together in the yard with all other trusses required for a specific job, until the
time comes for them to be loaded into a truck and delivered to the job site.

Step 4: SetOnce the trusses are delivered on site the construction crew goes to work
setting them. The roof trusses in this residential project were set on 24” cen-
ters, which is typical for this type of building construction. The placement of
the roof trusses occurred just after the house was framed and sheathed. Once
the trusses are in place the roofers are able to work on finishing the roof, while
other crew members finish completing work on the ground.
