Send us the architect's plans. We check them against the fire code, design the complete fire safety system, route the fire alarm wiring, measure a BOQ ready for your Schedule of Rates, build a 3D fire services model and hand over a submission-ready fire NOC drawing set, each finding with its clause cited. When the building is in use, our Fire Audit Pro app runs the fire audits.
Fire fighting design and drawing on a hotel ground floor: the plan is read, rooms are found, sprinkler heads and smoke detectors are placed, and the piping is routed from the mains down to the branches. Client name and title block hidden.
Fire fighting layout for fire NOC, drawn by Siya Habitats
Our completed fire layout for the hotel as an interactive 3D model: 440 sprinklers on one connected pipe network from the wet riser, 286 smoke and 5 heat detectors, hose reels, landing valves, the yard hydrant main and the fire alarm wiring. Turn it, switch systems on and off, and open each floor's sheet. Preliminary, for review and signature by a licensed fire consultant.
Interactive: drag to turn, pinch to zoom. Open the hotel model full screen. Client name and title block hidden.
In plain words, for a building owner or a fire officer: what happens to a drawing set once you send it to us.
What does a fire NOC drawing check include? We read the architect's drawings, find every requirement for the building's use and height in NBC 2016, NBCS 2026 and the state fire rules, check each one on the drawings with its clause cited, then draw our fire layout and run the same check on it.
The architect's drawings, as DWG, DXF or PDF. We read the floor plans, the levels and which floors are typical. Anything the drawings cannot settle, such as the use or a height without a section, we confirm with you instead of guessing.
Every requirement for that use and height, from NBC 2016, NBCS 2026 and the state rules, checked on the drawings. Each finding cites its clause.
Smoke detection, sprinklers and their pipes by bore, the wet riser and hydrants, hose reels, extinguishers, call points and hooters, the alarm panel, and the pumps and tanks (positions indicative).
Detection zones on every floor, loop cables along the corridors to every device, and a fire survival riser cable from the panel to each floor.
The same code check, run on our layout, so you see what changed and what is still open.
Counted off the layout, floor by floor, ready to price at your own Schedule of Rates: pipe by bore with grade and weight, the valve type, cables by type.
Every pipe, device and cable run of the layout in 3D, to walk the services floor by floor.
The fire layout sheets as PDF, and an editable DXF with our fire layers kept separate.
Status, stated plainly: what we hand over is a preliminary layout for review and signature by a licensed fire consultant. No hydraulic calculation is claimed. From the architect's drawings to a NOC-worthy fire layout, ready for that review.
A real architect's set for a ground plus ten storey office building, shown without its name, place, room labels or title blocks.
The same 33 code rules, run on the architect's set as received and again on our layout.

The one rule still marked not followed on our layout is sprinkler head spacing: a few heads sit closer than 2 m to a neighbour, flagged for our fire consultant to review. "Not determinable" means the drawings alone cannot settle the rule, so it is reported, not guessed.
Ground floor 1 / 12

Counted and measured off our layout, floor by floor, with the pipe grade and weight, the valve type and the cable type stated. You apply your own Schedule of Rates.
Can you produce a BOQ from drawings? Yes. Once our fire layout is drawn on the architect's plans, every device is counted and every pipe and cable run is measured off it, floor by floor. Each line carries its quantity and a rate column marked "x SoR rate" for your own Schedule of Rates.

| Sprinkler heads, pendent, 68 C | No. | 1,015 | x SoR rate |
| Sprinkler pipe 25 NB, heavy grade to IS 1239 (Part 1), 2.93 kg/m | m | 792.6 (2,322 kg) | x SoR rate |
| Sprinkler pipe 100 NB, heavy grade to IS 1239 (Part 1), 14.5 kg/m | m | 527.4 (7,648 kg) | x SoR rate |

A sample of the lines. The full BOQ also lists every other pipe bore with its weight, hose reels, extinguishers, hooters, the alarm panel, conduit and junction boxes. Pipe weights are from the IS 1239 (Part 1) tables; butterfly valves are kept off fire lines. Valve numbers come with the hydraulic design, which is not part of this preliminary layout, and the water tanks are civil items. No rupee figure: rates come from your own Schedule of Rates.
What the fire department asks for depends on what the building is used for and how tall it is. We read both from your plans, so there is no form to fill. Height is taken to the level the plans mark as the terrace, not the highest number on the drawing, which is a common mistake.
As your fire NOC consultant, we draft the fire fighting layout, check every rule the fire officer checks, and guide the submission.

From architect's plans to a fire NOC drawing set, ready to submit.
We will tell you what your fire NOC needs and what the drawings will cost.
Usually a site plan with fire vehicle access and the hydrant main, all floor plans with the fire layer, sections and elevation, a riser or down-comer schematic, tank and pump details, and a legend and consultant block. The local fire department may ask for more. Our fire NOC drawing checklist lists each item with its clause.
Yes. We prepare the fire fighting layout and the riser sheet on your architect's plans and check them against NBC 2016, NBCS 2026 and the Maharashtra and Delhi fire rules, with each clause cited. You get the architect's PDF with the fire layer added, a riser (down-comer) sheet and an editable AutoCAD (DXF) file, and we guide the submission.
No. We read the occupancy, height and storeys from the plans themselves, for example from the room labels and the level captions on the sheets.
It depends on the size of the building and how complete the architect's drawings are. We confirm the turnaround along with the price.
We check the set against NBC 2016, NBCS 2026 and the Maharashtra and Delhi fire rules, list every gap with its clause so it can be fixed before submission, and draw the fire layer. You get a submission-ready fire NOC drawing set. The decision on the NOC is the fire department's; we tell you in advance what the fire officer will look for.
The fire department of the local authority issues the fire NOC (in Mumbai it is often called the CFO NOC; in Delhi it is issued by the Delhi Fire Service). We prepare the drawings, tell you what the fire officer will look for, and guide the submission.
The fire department's fee is set in Schedule II of the Maharashtra fire rules as a percentage of the ready reckoner rate (ASR), so it depends on the building's use and area. It is separate from our charges for the drawings. Our fire NOC in Maharashtra guide explains the fee, provisional and final fire NOC, Form A and Form B.
Form A is the Licensed Agency's certificate that the fire prevention and life safety measures in a building comply with the Act, the National Building Code and the Indian Standard Code. The owner or occupier furnishes it when the installation work is complete.
It depends on the state and on what the building is used for, not on height alone. In Maharashtra the requirements are set occupancy by occupancy and height band by height band; our guide to fire norms by building height lists them.
We read the architect's drawings, find every requirement for the building's use and height in NBC 2016, NBCS 2026 and the state fire rules, and check each one on the drawings with its clause cited. Where the drawings cannot settle a rule, the outcome is "not determinable" rather than a guess. We then draw our fire layout and run the same check on it.
Yes. Once our fire layout is drawn on the architect's plans, every device is counted and every pipe and cable run is measured off it, floor by floor: sprinkler pipe by bore with its grade and weight, the valve type (sluice valves to IS 14846), detectors and fire alarm cable by type. Each line is left as "x SoR rate" for you to price at your own Schedule of Rates.
Yes, a 3D fire services model built from our fire layout: sprinklers and pipes, the wet riser, hose reels, extinguishers, detection and the fire alarm wiring, floor by floor. A worked example of a G+10 office building is online at siyahabitats.com/3d/office/. Like the layout, it is preliminary, for review by a licensed fire consultant.
