The single question every founder, COO, or GCC site lead asks first is also the hardest to answer honestly: "How long until we move in?" Most fit-out firms quote the construction window and quietly drop the three months of design, costing, and approvals that sit in front of it. That gap is where projects slip, board dates get embarrassing, and double-rent on an overlapping lease starts to bite. A realistic turnkey timeline for a 10,000–50,000 sq ft office in Mumbai or Pune runs roughly 14 to 24 weeks from signed brief to handover. the spread between those two numbers is almost entirely decided in the first month, not on site.
This is a phase-by-phase walk through how that calendar actually unfolds: what each stage produces, how long it genuinely takes, and the specific things that either compress the schedule or quietly blow it out. The point is to let you plan your lease, your IT cutover, and your all-hands move date against reality rather than a sales brochure.
Brief, test-fit and concept: weeks 0–4
Everything downstream inherits the quality of this phase, so it is worth resisting the urge to rush it. The brief captures headcount today and at 3-year projection, your ratio of focus to collaboration space, meeting-room mix, whether you run hybrid or full-attendance, and the non-negotiables (a townhall space, a lab, a dealing room, a creche). A serious workplace strategy conversation here saves you from rebuilding assumptions in steel and glass later.
The test-fit then proves whether your space program actually lands in the shortlisted floor plate. Core position, column grid, floor-to-floor height, and façade all dictate how many people and rooms you can realistically seat. We strongly recommend running test-fits before you sign the lease; it is the cheapest insurance in the entire process. Concept design follows: spatial zoning, the look-and-feel direction, and early 3D visuals so stakeholders are reacting to images, not floor plans. Budget 3–4 weeks, longer if decision-makers are spread across time zones.
GFC design and the BOQ: weeks 4–8
This is the stage that separates a turnkey delivery that holds its price from one that bleeds variations. GFC (Good For Construction) drawings are the fully coordinated set the site actually builds from. Architectural, MEP and HVAC, fire detection and suppression, electrical loads, data backbone, furniture (FF&E) layouts, and ceiling/services coordination resolved against each other so trades are not fighting for the same plenum on site.
The BOQ (Bill of Quantities) is priced directly off the GFC set. When the BOQ is built on half-baked drawings, every gap becomes a site instruction and a cost overrun later. Which is exactly why a fixed turnkey price is only as trustworthy as the GFC behind it. This is also where value engineering happens honestly: swapping specifications, rationalising ceiling types, or rethinking glazing to hit budget before procurement locks prices in. Expect 3–4 weeks of focused design and costing work. For deeper benchmarks, our office fit-out cost guide breaks down where the money actually goes.
Approvals and fire NOC: the variable that decides your date
Here is the phase most timelines lie about. Statutory approvals run partly in parallel with late design, but they are the single biggest source of unpredictable delay in Indian office fit-outs. The exact set depends on building and location, but typically includes:
- Building/society and landlord approval of your fit-out drawings. Grade-A developments in BKC, Lower Parel, Hinjewadi or Kharadi have their own technical review desks and turnaround norms.
- Fire NOC from the local fire authority, driven by your occupancy, partition layout, and suppression design. The most common critical-path item for offices above a certain area.
- MEP and electrical load sanction where you are adding HVAC tonnage or upgrading the incoming supply.
- Green certification pre-conditions if you are targeting IGBC, LEED or WELL. These must be designed in from concept, not bolted on at the end.
Realistic window: 3–6 weeks, and occasionally longer in older buildings or where the landlord's base-build documentation is incomplete. The firms that protect this phase are the ones who start liaison early and submit a clean, coordinated set the first time.
Procurement and long-lead items: weeks 6–12 (overlapping)
Good project leads do not wait for design to finish before they start buying. The moment GFC and BOQ are frozen, procurement runs in parallel with approvals and early site works. The discipline that matters here is identifying long-lead items early and ordering them first, because they. Not the carpentry. Set the back-end of your schedule:
- HVAC plant and VRF/VRV equipment. Frequently 6–10 weeks, the classic critical-path item.
- Workstations, task seating and loose furniture (FF&E). Imported or made-to-order lines can run 8–12 weeks.
- Specialist glazing, acoustic partitions, and feature lighting. Often 4–8 weeks.
- Switchgear, UPS, and access-control hardware. Variable, frequently underestimated.
A missed VRF order in week 6 surfaces as a four-week handover slip in week 14. This is precisely why turnkey delivery. Where one team owns design, procurement, and execution. Beats split contracts on schedule certainty: there is no finger-pointing gap between the designer who drew it and the contractor who has to buy it.
Execution, snagging and handover: weeks 8–22
On-site execution for a 10,000–50,000 sq ft office typically runs 8–14 weeks depending on area, ceiling complexity, and how many specialist zones (server rooms, labs, kitchens) you have. The sequence is broadly predictable: Cat-A base works (if the landlord has not already delivered them), then Cat-B. Your actual fit-out. Layered in a fixed order so trades do not undo each other:
- Demolition, civil works, and blockwork.
- First-fix MEP. Concealed electrical, HVAC ducting, plumbing, fire piping above the ceiling.
- Partitions, ceilings, flooring, and glazing.
- Second-fix MEP, joinery, and finishes.
- FF&E installation, AV, and IT commissioning.
The last two weeks are snagging. The systematic punch-list of every defect, alignment, and finish issue. Followed by handover with as-built drawings, warranties, and O&M manuals. Then the DLP (Defects Liability Period), usually 12 months, during which the contractor fixes anything that fails in normal use. A handover that skips a rigorous snag list just moves the defects into your occupancy, so treat snagging as a milestone, not a formality. See how this plays out across real delivered projects.
Timeline at a glance
The table below is a planning baseline for a typical 10,000–50,000 sq ft office. Phases overlap. The cumulative figures account for that, which is why they do not simply add up.
| Phase | Typical duration | What it produces |
|---|---|---|
| Brief, test-fit & concept | 3–4 weeks | Space program, validated test-fit, concept & 3D direction |
| GFC design & BOQ | 3–4 weeks | Coordinated construction drawings, priced BOQ, value engineering |
| Approvals & fire NOC | 3–6 weeks (parallel) | Landlord, fire, MEP & green sign-offs |
| Procurement & long-lead | 4–10 weeks (parallel) | HVAC, FF&E, glazing, switchgear ordered |
| Site execution | 8–14 weeks | Cat-A/Cat-B build, MEP, finishes, FF&E |
| Snagging & handover | 1–2 weeks | Punch-list closure, as-builts, O&M, keys |
| Total (brief → handover) | ~14–24 weeks | Followed by a 12-month DLP |
What compresses it: a single empowered decision-maker, a landlord who has already delivered Cat-A, early procurement of long-lead items, and a clean first-time approval submission. What extends it: late scope changes after GFC, fragmented stakeholder sign-off, monsoon-season civil delays, heritage or society constraints, and split design/build contracts. A well-run turnkey design-build model exists precisely to attack the second list. for enterprise occupiers, a GCC-grade fit-out programme adds the governance and reporting cadence that global headquarters expect.
Frequently asked questions
For a 10,000–50,000 sq ft office in Mumbai or Pune, plan on roughly 14–24 weeks from signed brief to handover, plus a 12-month defects liability period. Smaller, simpler spaces with the landlord's Cat-A already in place can land near the bottom of that range; large floors with heavy MEP, labs, or complex approvals trend toward the top.
Two things dominate: scope changes made after GFC drawings are frozen, and statutory approvals. Especially the fire NOC and landlord sign-off. Both are manageable if you lock the brief early, freeze design before procurement, and start approval liaison in parallel with late-stage design rather than after it.
Yes, and you should plan for it deliberately. Because the front-end design and approval work needs no physical site, you can run the first 6–8 weeks before your new space is even handed over for fit-out. Sharing your old lease's expiry date early lets us back-schedule the move date and minimise the overlap window.
