IMPORTANT NOTE: Truss Engineer's responsibility is solely for
design of individualtrusses based upon design parameters shown
on referenced truss drawings. Parameters have not been verified
as appropriate for any use. Any location identification specified is
for file reference only and has not been used in preparing design.
Suitability of truss designs for any particular building is the
responsibility of the building designer, not the Ïruss Engineer,
per ANSI/TPl-1, Chapter 2.

Addit¡onel stab¡lity bracing for truss system, e.g.diagonal or X-bracing, is ahvays required, See BCSI.2. Truss bracing must bo designod by an sngineer. Forwide tuss spacing, indiv¡duãl lateral brãces ûremselvèsmay require bracing, or altemâtive Tor Ibracing should be considercd,3. Neverexceedthestec* mäteriels ondesign loâding shown end neverinadequately braced trusses.4. Provide copies of this truss d€s¡gn to the buildingdesigner, erect¡on superyisor, property owner andall other ¡nteresled pårties.5. Cut members to bear t¡ghtly against each other,6. Place plates on each face of truss at eachjoint and embed fully. Knots and wane at jo¡ntlocations are regulated by ANSI/TPI 1.7. Design assumes trusses will be suitâbly protected fromthe environment in accord with ANSI/TPI 1.8. Unless otheM¡sê noted, moisturô content of lumbershall not exceed I 9% at time of fabrication.L Unless expressly noted, th¡s design is not applicable foruse with fire retardant, preservat¡ve treated, or green lumber10. Camber is a non-structural consideration and is therespons¡bility of truss fabricator. General practice is tocamber for dead load deflection.I 1, Plate type, size, orientâtion ând location dimensionsindicated are minimum plating requirements.12. Lumber used shall be of the spec¡es and s¡ze, andin all respects, equal to or better than thatspecified.13. Top chords must be sheathed or purlins provided atspac¡ng indicated on des¡gn.14. Bottom chords requi¡€ lateral brâc¡ng at 10 fr. spac¡ng,or less, if no ce¡ling is installed, unless otheMisê noted.15. Conneclions not shown are the responsibility of others,16. Do not cut or alter buss member or plate without priorappÍoval of an engineer.17. lnstall and load vertically unless indicated otherwisê.18. Use of green or treâted lumber may pose unãcceptebleenv¡ronmental, heatth or performance risks. Consult withpro¡ect êng¡neêr before use.19. Review âll port¡ons oflhis design (front, back, wordsand p¡ctures) before use. Reviewing p¡ctures aloneis not sufficient.20. Design assumes manufaclure in accordance withANSI/TPI 1 Quality Criteria.
