Separation Prevention ❑ 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. ROOF TRUSS NOTES: DO NOT CUT, DRILL, NOTCH, OR OTHERWISE DAMAGE TRUSSES.

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.
