Submit representative samples of wood species indicated, of the grade and finish specified, for Architect’s approval.
Furnish complete Frame Plans at completion of frame design work.
Frame plans shall be certified by a professional structural engineer registered with the governing body in the appropriate State.
Truss design shall provide the required stability and resistance to gravity loads.
No frame components shall be ordered or fabricated prior to the approval of the Frame Plans by the Architect.

Timber shall be sized according to engineering requirements. Minimum size shall be 100mm x 100mm in all directions.
Timber species:
F7 Seasoned Pine
F7 Green Oregon
F14 Green Hardwood
F8 Green White Cypress
F14 Green Hardwood
F8 Seasoned Oregon

Furnish and install all necessary hardware and metal shapes required for assembly and erection of the framing.
All steel shapes, plates, and tubes, unless otherwise specified, shall conform to AS4100
All other steel shapes, plates, tubes, etc. shall be thoroughly cleaned and given one heavy shop coat of an approved primer (black), well worked into all joints and open spaces. After erection, touch-up as required. Surfaces which are not accessible for field painting shall have one shop coat of black paint before leaving the shop.
Bolts shall be blackened/zinc/galvanized with blackened/zinc/galvanized washers and nuts.

Joinery shall be in best of the early English tradition, designed for strength, shrinkage, checking, and twisting. **OPTIONAL** Metal connections shall not be used unless required by the structural design, and, in those cases, must be concealed and held at an absolute minimum, meeting the Architect’s approval. All workmanship shall be of the very highest quality.
Or steel as detailed on Structural Drawings.
All joinery shall be accurately cut so as to make a neat, snug fit.

Frame components and assemblies must be checked for dimensions and anchorage accuracy before erection.
Temporary bracing shall be provided to adequately protect all persons and property and to insure proper alignment.
Padding or non-marking slings shall be used during mechanical lifts.
The assembled trusses shall be reasonably straight, plumb, level and square. Portions of the structure not adequately braced by design shall have temporary braces until the cladding is applied.
All joints shall be reasonably tight.
All joints that require pegging shall have pegs driven until snug. Pegs shall protrude 10mm on both sides of the joint except where they should be flush as directed above. Broken pegs shall be removed and replaced. Pegs with a mushroomed head shall be cut off below that portion.
Tools used to drive or pull joints together shall not permanently mar the finished surfaces of the trusses.
