Notes:
1. Builders FirstSource's (BFS) sole responsibility is to design trusses and components to the dimensions and design
criteria provided to BFS by the customer. The design of the remaining portions -of the buildiig_is the responsibility of the
-building designer, engineer of record, or the customer / contractor in the absence of a design professional.
2. The design and specification of the permanent and temporary bracing is the responsibility of the building designer per
TPIA as referenced in the building code. The bracing documents we provide are the minimum standards that are'to be
verified or enhanced by others as needed for -the specific project .
3. All wood component products supplied by BFS shall be used in dry service applications (Moisture Content<197o) U.N.O.
4. Multi -ply girder trusses are to be attached together per the nail or bolt schedule on the specific truss drawing.
5. The building designer, engineer of record, or customer shall resolve any issues or connections between trusses and
other structural members not provided or specified by BFS when needed. ,
6. Truss Placement Plans and Truss Drawings are the property of BFS and may not be used or reproduced without the
written approval of BFS. Products remain property of BFS until Paid in Full.
7. Install Trusses per the BFS Placement Plan, Industry Standards, and Code Requirements. Install Recommended floor
Truss -Strongbacks @ 10' O.C. DO NOT -INSTALL TRUSSES UPSIDE DOWN. Avoid conflicts with plumbing & other trades.
8. Truss Drawings indicate standard -loads and added loads in the load cases section. Do not apply structural loads to any
truss if that load is not shown on the truss drawing. Verify stick framed roof loads transfer where allowed-& designed for.
-Erection and Bracing: The customer accepts full responsibility for -the erection and -bracing of these components -and
shall supervise any subcontractor or other party that is carrying out this work. We have included industry standard
erection, temporary bracing, and fall protection guidelines as -a -minimum. guideline. However, the customer or general
contractor must insure that these minimum guidelines are met as well as any additional -specifications by the project
architect / engineer. Clearly, you must -provide temporary -bracing as shown in 81_to.avoid erection failures and the
resulting potential financial loss or injury. -**221./.2" LONG 2X4 BLOCKS DO -NOT COUNT AS' BRACES**
Stability: Until the building is completely built and -sheathed in accordance to the project plans by the building -designer. /
engineer of record and meeting all code and local requirements, it.may be unstable and present a safety hazards unless
properly braced. The builder / framer shall build and properly brace the structure -by floor---do-•not build additional stories of
construction on a -poorly braced structure below. Instability may increase=wi#h building•dimensions -particularly height
Winds: Buildings under construction may be vulnerable to high wands. The builder and framershall consider all weather
conditions including the potential for winds -when deciding to set trusses. If high winds are -expected, truss erection should
be postponed or a consulting engineershould specsi y.additional temporary bracing required to meet the possible
conditions.
Issues: If you encounter any jobsite installation issues that appear to involve the modification of the truss or component,
please contact your BFS Sales Representative immediately. The representative will determine the nature of the issue and
help facilitate its remedy. Do not make alterations or repairs prior to receiving repair details or instructions from BFS. If the
issue is manufacturing related BFS reserves the right to repair or replace the component in question. If the component in
question is not structurally stable, install additional shoring to insure project safety.
Charge Backs: Charge backs will not be acceptecl unless agreed upon by an aumorized ut-5 Manutactunng
Representative prior to the repair or modification in question. It is the responsibility of the contractor to inform BFS of any
error, problem, or defect prior to or during setting of the components. In the event of a charge back, an authorization
number will be given by BFS for an agreed upon specific amount to resolve the issue. This authorization number must
accompany any charge back to BFS to be valid.

1. This Truss Placement Diagram is Intended to serve as a
guide for truss installation. This Diagram has been prepared
by a Tess Technician and is not an engineered drawing.
2. The responsibilities of the Owner, Bu➢dng-Designer,
Contractor, Tress Designer, and Truss -Manufacturer WWI be
as defined by the TPI 1 National Standard
3. The wood components shown ontiis.diagrarn are to be
used In dry service (moisture content<19%) and non -toxic
environmental applications. The metal plates and hangers
are galvanized.to the G60 Standard unless noted otherwise.
4. Refer to the Truss Design Drawings for specific
information about each Individual truss design.
S. The Truss Technician shall provide Truss -to -Truss
Connection Requirements. Any special or other connection
shall be the responsibility of the Building Designer.
6. The Truss Placement Diagram and Truss Design
Drawings are the property of Builders FlrstSource andmay
not be reused or reproduced in part or in total under any
circumstances without prior written authorization.
7. In some cases, field framing, may -be required to achieve
the final appearance shown on the Construction Documents.
B. Field framing, Including valley rafters, installed over rod
busses shall have a knee brace from the rafterto the toss
top chord at intervals of 48' on center (D.C.) or. less.
Stagger knee braces from -adjacent rafters such that the load
Is distributed uniformly over multiple truss locations and not
concentrated at one location or along one truss.
9. Truss Top-Chordsshail be fully sheathed or have lateral
bracing (purffns) spaced at 24' O.C. or less. Truss Bottom
Chord Bracing shall not exceed the mmdmum shown on the
Truss Design Drawing. Feld framed bottom chord floor or
ceiling attachments shall be spaced at24' O.C. or less.
Proper Bracing prevents buckling of individual truss
members due to design loads.
10. This Placement Diagram is based upon the supporting
structure being structurally adequate, dimensionally cored
square, plumb, and level to adequately support the tosses
The foundation design, structural member stung, load
transfer, bearing conditions, and the stricture's compliance
with the applicable building code are the responsibTdy of the
Owner, Building Designer, and Contractor.
11. If Piggyback Trusses are included In this project, tefer to
the Mftek Piggyback Connection Detail applicable for the
project details and wind load category.
12. The Contractor shall follow the SBCA TTB Partition
Separation Prevention and Solutions for truss attachment to
non -load bearing walls and carefully complete these details
to avoid gypsum wall board related Issues.
WARNING:
TRUSSES MUST BE BRACED DURING INSTALLATION.
FAILURE TO DO SO MAY RESULT IN INJURY OR DEATH.
