General Specifications

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.

The foundation columns shall be accurately place and shall extend 4’-0” minimum below grade. The foundation column shall have ½” diameter x 10’long 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.

(b) Location of all joints.

(d) Design loading to include, as applicable:

(1) Top chord live load.

(2) Top chord dead load.

(3) Bottom chord live load.

(4) Bottom chord dead load.

(5) Concentrated loads and their points of application.

(e) Adjustments to lumber and plate design values to include modification for, as applicable.

(1) Moisture service conditions.

(2) Temperature.

(3) Preservative treatment.

(4) Fire retardant treated wood.

(5) Duration of load.

(6) Flexure.

(7) Shear.

(f) Each reaction force.

(g) Each axial force (Heel panel axial forces shall not exceed 25,000#).

(h) Lateral bracing requirements:

(1) Top chord brace (roof purlin) spacing.

(2) Bottom chord brace spacing.

(3) Web bracing, as applicable.

(i) Plate type, Thickness or gauge, size; basic plate design value (specifying gross or net

Value); and the dimensioned location of each plate except where symmetrically located relative to the joint interface.

(j) Lumber size, species, and grade for each member.

5. Design calculations for bending moments shall be available for the designer.

Roofing and Siding Panels:

Metal panels are G-90 (Max-Rib 90) zinc-treated, hot-dipped galvanized or GALVALUME ™ (Max Rib Ultra) 80,000#/SI minimum yield strength structural grade sheet steel. The paint process is a Kynar 500/Hylar 5000 Fluropon paint system. Utilizing the full strength 70% PVDF (fluoropolymer) resin and durable ceramic pigmentation. Panels shall be fastened with nails or screws, which are compatible to the panels in both life expectancy and environmental stability. All panels will be one piece unless lengths greater than 40 feet are required or the panels must be shortened to accommodate certain building features.
