I need a CAD design for a bifurcated staircase. The design should be suitable for both architectural visualization and manufacturing drawings. Requirements: - Both 2D drawings and 3D models - 2D drawings must be highly detailed with annotations Produce builder/engineer-ready drawings for a bifurcated wood stair with a square 48″×48″ split landing and 90° side flights. Drawings must be fully dimensioned, code-sane, and ready for field use and permit review. Key constraints (lock these) Total rise: 144″ (12′) Risers/Treads: 20 risers total → 12 main + 8 per side, riser = 7.20″, tread/going = 10.5″ Main run width: 72″ at first tread, tapering linearly to 48-1/2″ at the split (≈ 2″/tread × 12) Split landing: 48″ depth × 48-1/2″ throat (clear between inner guards) Across the split (finished-to-finished): 47-3/4″ / 48-1/2″ / 47-3/4″ (left flight / throat / right flight) → fits 12′ bay with a hair of tolerance Side flights: 90° from main, constant 47-3/4″ overall width, 8 treads to the upper landing Headroom: maintain ≥ 6′-8″ above all nosings Room envelope: 12′ soffit-to-soffit across the split; approx. 32′ depth front-to-back Deliverables A1 – Plan (Scale 1/2″ = 1′-0″ or 1/4″ = 1′-0″) All widths called out (72″→48-1/2″ taper schedule on main; 47-3/4″ side flights; 48-1/2″ throat; landing 48″ depth) Dimension strings: overall, centerlines, clearances; soffit lines; newel/post centers Callouts for blocking at landing corners and inner-throat corners A2 – Sections/Elevations Side elevation of main + one side flight showing 20 risers @ 7.20″, treads @ 10.5″ Slope angle, nosing projection (≈1″), headroom check line, finish floor references Typical handrail height (34–38″, tag 36″ typ) and guard height on landings (≥36″; note to verify local) A3 – Details & Schedules Main-run taper schedule per tread (12 rows, first = 72″ … last = 48-1/2″) Typical tread/riser/skirt/stringer sections (materials + thicknesses) Newel/post base plate detail & blocking callouts (landing corners + inner throat) Notes on tolerances (≤3/16″ riser/tread variance), adhesives/fastening, field-verify dimensions Digital files PDF set (vector) and DWG/DXF (model space, units = inches, layers for walls/stairs/dims/notes) Fonts/styles standard; dimensions readable at plotted scale; include title block with date/revision Scope boundaries (what you do / don’t do) Include: Wood stair geometry, landings, stringers, skirts, treads/risers, newel/post locations, rail height lines. Optional: Structural calcs (unless offered as add-alt); wrought-iron panel fabrication drawings (by fabricator). Coordinate clear widths for iron. Materials (assumed): White Oak treads & landing nosing (site finish); paint-grade risers/stringers/skirts. Codes & performance (assume IRC unless noted) Clear width: ≥36″ between handrails (with 47-3/4″ overall, we’re comfortably above this) Landing depth: ≥36″ (we’re 48″) and ≥ stair width served Openings: 4″ max through guards; 6″ triangular at tread/riser/bottom rail What I will provide you: Existing PDFs (concept plan/sections) + this brief Site photos and any framing/soffit references available Acceptance criteria: All locked dimensions above are shown and consistent (spot-check: across the split = 47-3/4 / 48-1/2 / 47-3/4; landing 48″ depth; main taper ends 48-1/2″). No collisions with 12′ soffit lines; headroom line ≥6′-8″ everywhere. Readable plots at chosen scale; clean layer naming; proper units. Notes cover materials, blocking, tolerances, and field-verify. 1 round of markups included; turnaround for revisions 2–3 business days. Timeline & budget First draft: 5–7 days from award Revisions: 2–3 days per round Budget: $200 - 250Y (fixed-fee), payable at 50/50 (concept/final) or milestone per sheet What to include in your bid: 2–3 examples of residential stair drawings you produced (plan/section/detail) Confirmation you’ll deliver PDF + DWG/DXF, scale, and layer standards - PDF preferred Any assumptions or RFIs (e.g., final nosing profile, exact rail profile, finish floor thickness)
