Sample-deck-Drawing

Oct 23, 2026

General construction drawing notes governing design and execution across multiple structural elements: verify discrepancies with the engineer, do not scale drawings, and ensure the structure remains stable and not overstressed during works. Verify all setting-out and off-site dimensions before commencement, using millimetres unless stated. Specify compliance with relevant Australian standards and statutory requirements, including wind load parameters (AS/NZS) and design live loads. Include site preparation and foundation checks, structural timber quality, concrete grade and curing, and structural steel detailing, welding, and bolt requirements.

FAQs

What general instructions apply to these drawings before construction starts?

The drawings must be read with all other consultant drawings and specifications, discrepancies must be referred to the engineer, and the engineer’s drawings must not be scaled. Relevant setting-out and off-site dimensions must be verified by the contractor before construction begins.

How are wind loads and design live loads defined?

Design wind loads follow AS1170.2-2001 with the listed return period, region, terrain category, shielding, topographic factor, wind velocity, and pressure coefficients. Design live loadings follow AS/NZS1170.1:2002, including the deck loading of 3.0 kPa.

What key requirements govern foundations and structural timber?

For foundations, check footing excavations for organic material and rubbish, remove any found material, and compact disturbed bottoms to the specified relative dry density. For timber, follow AS1720 and related codes, reject abnormally green or split timber, ensure timber at joints has no defects, and protect timber from weather while meeting durability and fastening requirements.
