What a complete set contains
| Drawing | Purpose |
|---|---|
| Demolition and construction plan | What comes out, what goes in |
| Furniture and joinery layout | Position of everything |
| Flooring plan with pattern and start point | Where the first tile is laid |
| Reflected ceiling plan | Lights, diffusers, sprinklers, speakers, coordinated |
| Electrical plan with point heights | Every socket, switch and point, dimensioned |
| Plumbing plan | Supply, drainage, falls, isolation valves |
| Joinery elevations and sections | How each unit is built |
| Finish and hardware schedules | Codes, brands, models for every material |
Why the set prevents variations
Every decision that is not on a drawing gets made on site by whoever is standing there, and every such decision is a potential variation. A socket at the wrong height, a shelf at the wrong level, a tile pattern starting from the wrong corner — none of these are expensive in themselves, and all of them are expensive to undo once fixed. The set is where those decisions get made in advance, cheaply, on paper.
The reflected ceiling plan, in particular
It is the sheet that stops the most arguments. Downlights, cove runs, AC grilles, sprinklers, smoke detectors, speakers and curtain pockets all live in the same plane, and coordinating them on one drawing is the difference between a clean ceiling and a random scatter. Insist on it, and insist that it is dimensioned rather than indicative.
A revision register belongs with the set: one sheet listing every drawing, its current revision and the date it was issued to site. On a flat with thirty sheets and a twelve-week programme, it is the cheapest document in the project and the one that settles most disputes about what was approved.
Working drawings versus design drawings
Design drawings communicate intent to a client. Working drawings communicate instructions to a builder. They are different documents for different readers, and a project quoted on design drawings alone will generate its detail on site. If a studio's fee looks unusually low, check whether the working drawing set is in the scope. See BOQ, our process and design fees.
Frequently asked questions
What is the difference between working drawings and GFC drawings?+
None in practice — GFC, or good for construction, is the status stamped on a working drawing once it is released for site. The term signals that this version supersedes anything issued earlier.
How much do working drawings cost?+
₹35–90 per sq ft of carpet area as a standalone deliverable, or bundled into a design fee of ₹75–250 per sq ft. On a turnkey contract they are usually included, though you should confirm that you receive copies.
Do I get to keep the working drawings?+
You should — they become as-built records you will want the first time anyone drills a wall. Ask for them at handover in PDF and, ideally, in CAD. Some studios retain copyright while granting use; clarify this at the start.
Can a project be built without working drawings?+
It happens constantly, and it is why so many projects end in variation disputes. Without the set, the decisions are still made — just on site, verbally, by whoever is present, with no record of what was agreed.
