Project Description
Project summary
This job is to set up drawing templates and produce a small, coordinated drawing set for a non-structural internal room modification (approx. 6,000mm x 6,000mm). Construction is timber framed with Gyprock (plasterboard) lining and Foilboard (insulation). Drawings are for proof of concept.
Scope, assumptions & standards
Scope: Non-structural internal modification only (walls/ceiling linings, framing layout representation, insulation and fixing details). No footing/slab, roof structure, or load-bearing design is to be engineered as part of this drafting package.
Assumptions: Final framing member sizes, spacings, and any hardware schedules will be supplied where required. Draftsman to leave placeholders where details are not yet provided and flag as “Client to confirm”.
Drafting conventions: Apply Australian technical drawing conventions consistent with AS 1100 (architectural drawing) where practical, including clear dimensioning, lineweights, symbols, and sheet presentation.
Reference installation guidance (for depiction only): Gyprock lining details should generally align with manufacturer guidance and AS/NZS 2588 product compliance (do not copy proprietary details verbatim; draft a typical fixing diagram and note “confirm to manufacturer requirements”).
Required deliverables (templates + drawing sheets)
A-001 Room Layout / Overview (Plan) 1:50 Simple plan view with key dimensions, openings, and references to elevations/sections.
A-201 Interior Elevation(s) + Layered Overlays 1:50 Elevation view(s) with CAD layers for joists, insulation, and Gyprock (see layer requirements below).
A-501 Typical Section + Fixing/Hardware Detail 1:10 (detail) / 1:20 (section) Section cut showing build-up and a typical hardware fixing diagram (e.g., hanger/bracket/screw fixing as applicable).
CAD setup & template requirements
Units: Millimetres (mm). Model space 1:1. No scaling in model space.
Sheet size: A3 preferred (confirm). Provide an A1 option if requested later.
Title block: Include fields for Project, Address/Site, Drawing Title, Drawing No., Scale, Date, Revision, Drawn, Checked, Sheet Size, and General Notes.
Native files: DWG (AutoCAD-compatible). If produced in Revit/other, also export clean DWG.
Issued set: PDF plotted to scale, monochrome/greyscale lineweight output suitable for printing.
Lineweights: Use a clear hierarchy (e.g., heavy for cut/primary outline, medium for framing elements, light for insulation/notes). Keep text legible on A3.
Layering (minimum): Provide separate, named layers for: Walls/Room Outline, Openings, Dimensions, Text/Notes, Timber Joist Layout, Insulation Layout, Gyprock Lining, Hardware/Fixings, Section Cuts/Markers. Layer names can follow your office standard, but must be unambiguous and grouped logically.
Blocks/Symbols: Use consistent symbols for section/elevation markers, grid/centreline (if used), and hardware callouts.
Drawing content requirements (by sheet)
A-001 Room Layout / Overview (Plan)
Draw room footprint 6,000 x 6,000 (confirm internal vs external dimension and note clearly).
Show wall thicknesses, proposed framing linework (schematic), and lining extent.
Locate and dimension openings (doors/windows), including swing (door) and sill/head heights if provided.
Dimensioning: overall and critical set-out dimensions from a nominated datum corner.
Show reference markers for elevation view(s) and section cut(s).
Add a small key/legend (symbols, abbreviations used).
A-201 Interior Elevation(s) + Layered Overlays
Provide at least one interior elevation (more if required to clearly communicate the modification). Identify elevation direction and wall reference.
Layered overlays (must be on separate layers):
Timber joist layout layer: Show joist direction, spacing, and any trimmers/boundary members as applicable. Client will provide joist sizing/layout detail; draftsman to depict and annotate based on provided info.
Insulation layout layer: Show extent, type callout placeholder (e.g., “bulk insulation to client spec”), and any gaps/edge conditions that need noting.
Gyprock lining layer: Show lining extents, sheet orientation if required, and any control joints/edge trims if nominated.
Include key vertical dimensions (floor-to-ceiling, lining build-up thickness if known) and any set-out heights for openings/fixtures if provided.
Notes should clearly state “non-structural; for lining/framing coordination only”.
A-501 Typical Section + Fixing/Hardware Detail
Section (1:20 recommended): Cut through a representative portion showing timber framing, insulation zone, and Gyprock lining. Indicate member labels (stud/joist/batten as applicable), lining thickness placeholders, and fixing substrate.
Hardware fixing detail (1:10 recommended): Provide a simplified detail illustrating the hardware fixing concept (e.g., bracket/hanger/angle or typical screw fixing) including:
Hardware item callout (type/size placeholder if not provided).
Fastener type placeholder (e.g., “Type W screw to timber”) and indicative spacing note (“confirm to manufacturer/spec”).
Minimum edge distances / fixing zones shown diagrammatically (no engineering values unless supplied).
Include a brief general note on confirming fixings to project specification and relevant manufacturer instructions.
Information required from client (before drafting starts)
Site/address (for title block) and any project/job reference number.
Existing room measurements confirmation (internal clear dimensions vs external framing dimensions), wall thicknesses, and ceiling height(s).
Opening schedule: door/window sizes and locations, swing direction, sill/head heights (if applicable).
Joist layout details: joist direction, spacing, sizes, trimmers/openings, and any nominated hardware (client-supplied).
Insulation requirements: type (bulk/batt), nominal thickness/value if known, and extent.
Gyprock requirements: board thickness/type (standard/wet area/fire/acoustic if applicable), ceiling vs wall lining requirements, and any special areas.
Any sketches, marked-up photos, or redlines showing the intended modification.
Handover, QA, revisions & timing
Handover package: DWG (native), PDF set (plotted to scale), and any referenced plot style file if used.
QA checks: All views coordinated (markers match, dimensions consistent), scales correct, layers separated as requested, title block completed, and revision/date set.
Revisions: Include 1–2 rounds of minor amendments (e.g., dimension corrections, note updates). Any scope change (additional sheets/details) to be quoted separately.
Timing: Provide an estimated turnaround once inputs are received (e.g., first issue within X business days)
