A residential building has 30-80 door + window units; a commercial / institutional building has 200-2000+. Each unit has a specific design, material, hardware specification, and acceptance criteria. The Door & Window Register tracks every single one through: design approval → procurement → site receipt → installation → testing → defect rectification → handover.

Without the register, the contractor's snag list is unmanageable, the PMC can't sign off the building until every unit is documented as accepted, and the client doesn't know what's in the building for warranty / maintenance purposes. The register is the primary handover document for the door + window trade.

Setup: extract every D&W unit from architectural drawings — typical residential might have 30 units (D-01 through D-15, W-01 through W-15). Each gets a row.

Per-unit fields: - Unit reference (D-01, W-12, etc.) - Location (Room name + floor) - Type (single shutter, double shutter, sliding, casement, fixed) - Material (wood / steel / aluminium / uPVC) - Specification reference (IS 4351 for hinges, IS 1003 for wooden doors, IS 1948 for aluminium, etc.) - Supplier + batch + delivery date - Installation date + crew - Inspection results (alignment, sealing, operation) - Defects + rectification status - Final acceptance signature

Updated continuously through the trade execution; consolidated at handover.

Who fills: Site engineer (doors/windows trade). Who reviews: PMC engineer + architect + client representative for snag review.

1. Hardware not as specified — drawings call for SS 304 hinges; supplier delivered MS painted hinges. Register entry forces verification at delivery.

2. Operating defects — doors that don't close properly, sticky locks, leaky window seals. Register's inspection column documents these for rectification.

3. Glass type mismatch — toughened glass specified but ordinary glass delivered. Per IS 2553, safety glass mandatory in many locations — wrong glass is a safety violation.

4. Insufficient acoustic/thermal performance — uPVC windows must achieve specified U-value or STC rating for green-building credits. Register documents the spec + verification.

5. Missing IS conformance — IS 1003 (wooden doors), IS 1948 (aluminium), IS 12433 (PVC) compliance required. Register entry must reference + verify.

Codes referenced depend on door/window type: - IS 1003 Parts 1-2 — Specification for timber panelled and glazed shutters - IS 1948:1961 — Aluminium doors, windows, and ventilators - IS 12433 Parts 1-2 — Specification for unplasticised PVC doors - IS 4351:2003 — Specification for steel door frames - IS 2553 Part 1:1990 — Safety glass (mandatory for door panels + low windows) - IS 2202 Parts 1-2 — Specification for wooden flush door shutters

Companion QA/QC: Other building-trade registers (masonry, flooring, painting) — all feed into the final handover documentation set.

PMC workflow: D&W register typically consolidated into the Snag List / Punch List for handover. Final closeout signs off the trade.
