Laminated
Foundation Columns and Footings:
The
structural nail laminated foundation columns shall be three members No. 1 or
better Southern Pine, Kiln dried to 19% moisture content. Foundation columns
shall be pressure treated with a wood preservative to retention of 0.8 pounds
per cubic foot and kiln dried after treating to 19% maximum moisture content.
The wood preservative shall be Chromated Copper Arsenate Type III, Oxide type;
or equal as listed in Federal Specification TT-W-571J. The preservative shall
penetrate 100% of the sapwood. A letter of certification from the wood
preserver shall be furnished which certifies the 0.8-pcf preservative retention
for a 0 to 0.75 assay zone.
The
foundation columns shall be accurately place and shall extend 4-0 minimum
below grade. The foundation column shall have ½ diameter x 10long steel rod,
located 3-1/2 up from the base, and extending through all (3) members. Base of
column shall be set in a footing of 28 day test verified 3000 psi compressive
strength dry concrete mix, half under and half around to permanently attach the
footing and foundation column. The footing shall bear on undisturbed soil.
Footing size shall be determined from applied structural loads and 4000 #/S.F.
presumptive soil bearing capacity. After accurate placement of foundation
column and specified footing, hold shall be backfilled with dry, debris-free
dirt compacted in 8 lifts.
Laminated
Upper Columns:
No. 1 or better
Southern Pine nail and glue laminated repetitive S4S members of 19% maximum
moisture content shall be sized according to dimensions of structure and
required structural loads.
Foundation Column to Upper Column Connection:
Structural
design shall show, by test or calculation, the foundation column to upper column
connection to be adequate for all imposed bending and axial forces.
Splash
Boards:
Splashboards are No. 2 or better Southern Pine nominal 2x8 S4S pressure treated to a net retention of 0.4 pounds per cubic foot with chromated copper arsenate Type III, Oxide type, in accordance with American Wood Preservers Association Specification C2.
Eaveboard:
Sidewall eaveboards shall be 2x6 No. 2 Spruce-Pine- Fir or better, and shall be
beveled on the top edge at the same degree as the roof slope.
Framingboard:
Wall girts shall be 2x6 No. 2 Southern Pine, 19% maximum moisture content spaced
approximately 24 to 30 o.c., with all ends bearing into wide face column.
Roof purlins shall be recessed between trusses, on edge, and attached to trusses
with adequate fasteners. Continuous 2x4 lateral bracing shall be provided as
required in truss specification. All other framing lumber shall be standard
grade or better unless specified differently on plans. All lumber shall be free
of warping, twisting, or splitting.
Specification for Metal Plate Connected Wood Trusses:

revised to current date.
4.
Truss members and joints must be designed in
accordance TPI-95. All truss design must be
