A contingency line that reads "10% of budget" without saying what it covers is not a contingency plan. It is a rounding error waiting to be discovered mid-project. The number that matters is not the percentage on the cover sheet, it is which risks that percentage is actually meant to absorb, and whether the project has already burned through it before construction even starts.
Vektor Spaces structures contingency around three separate pools rather than one blended figure, because design risk, procurement risk, and site risk behave differently and get consumed at different points in the programme.
Why a single contingency percentage fails
A blanket 10% or 15% contingency assumes every fit-out carries the same risk profile. It does not. A shell-and-core floor with a clean structural grid carries far less risk than a floor with an irregular column layout, a shared base-build HVAC system, or a landlord with a slow approval cycle. Treating both projects the same way either overprices the low-risk floor or underprotects the high-risk one.
The fix is to size contingency against the specific risks in that project's brief, not against a rule of thumb copied from the last job.
Design contingency: the brief-freeze risk
Design contingency covers the cost of decisions the client has not yet made at the time of pricing. headcount that may still grow, a meeting-room mix that has not been finalised, or finish options still under review. This pool typically runs 5–8% of the design and FF&E budget and should shrink to near zero once the workplace strategy brief and test-fit are signed off.
If design contingency has not shrunk by the time GFC drawings are issued, that is a signal the brief was never actually frozen. Track it as a live number through the design phase, not a figure set once at the start.
Procurement contingency: price and lead-time risk
This pool absorbs currency movement on imported finishes, price escalation on steel and glass between quotation and order, and the cost of expediting a long-lead item that slips. A typical range is 4–6% of the procurement value, weighted higher on projects with imported AV, façade glazing, or specialist MEP plant.
| Risk category | Typical contingency | What triggers drawdown |
|---|---|---|
| Design changes pre-freeze | 5–8% of design/FF&E | Headcount shift, finish reselection, scope addition |
| Procurement and price escalation | 4–6% of procurement value | Currency movement, vendor price revision, expediting |
| Site and construction risk | 5–10% of construction value | Concealed conditions, MEP clashes, landlord-driven rework |
Construction contingency: the site-discovery risk
Concealed conditions are the classic driver here: a slab that is not level to drawing, base-build services that do not match the as-built, or a fire-rated wall that was never documented. Construction contingency usually sits at 5–10% of the construction value, and it is the pool most exposed to the same coordination clashes that cause schedule delays. Money and time risk are rarely separate on a live site.
How a fixed-price contract changes the contingency conversation
Under a traditional multi-contractor procurement route, the client typically carries all three contingency pools directly, because no single party owns the outcome. Under a genuine turnkey design-build model, the contractor carries construction and much of the procurement risk inside the fixed price, so the client's real exposure narrows to design decisions still open at signing. That is why a signed test-fit before pricing matters more under a fixed-price contract than under a traditional one: it is the difference between a number that holds and a number that needs a change order in month two.
Tracking drawdown instead of setting and forgetting
A contingency line that is set once at signing and never revisited is not being managed, it is being ignored until something goes wrong. The more useful approach is a live drawdown log reviewed at each major milestone: brief freeze, GFC issue, procurement release, and practical completion.
At each checkpoint, three questions should have clear answers: how much of each pool has been used, what specifically consumed it, and whether the remaining balance still covers the risks still open in the programme. If the design pool is exhausted before GFC issue, that is an early warning that the brief was never actually frozen, not a reason to quietly draw down construction contingency to cover it.
A worked example: a 25,000 sq ft floor in BKC
Consider a 25,000 sq ft floor fit-out in a Grade-A BKC tower with a total project value of roughly ₹3.75 crore at a mid-market ₹1,500/sq ft rate. A risk-weighted contingency structure might look like this: design contingency at 6% of the ₹90 lakh design and FF&E allocation (₹5.4 lakh), procurement contingency at 5% of the ₹1.5 crore procurement value (₹7.5 lakh), and construction contingency at 8% of the ₹2.1 crore construction value (₹16.8 lakh) given the building's older base-build MEP.
That totals roughly ₹29.7 lakh, or just under 8% of total project value, weighted toward the construction risk this specific building actually carries rather than a flat 10% applied blindly across every category. A newer building with a cleaner base-build might justify a lower construction contingency and a correspondingly lower total percentage.
Contingency is not a substitute for value engineering
A well-funded contingency pool should never be treated as permission to skip value engineering during design development. The two serve different purposes: value engineering removes cost from the base estimate before it is locked, while contingency absorbs risk that remains after the estimate is locked. A project that relies on contingency to cover costs that should have been value-engineered out during design is really running an under-scoped base estimate with a bigger safety net, not a well-managed budget.
Frequently asked questions
Most Pune and Mumbai fit-outs carry a combined contingency of 12–20% across design, procurement, and construction, weighted by the specific risks in that project's brief and building rather than applied as one flat number.
No. It shifts most procurement and construction risk to the contractor inside the fixed price, but the client still carries design contingency for decisions not yet made at signing, such as headcount growth or unresolved finish selections.
At brief freeze, at GFC issue, and at handover. Each milestone should show contingency drawing down as risk retires, not sitting untouched until it is needed for an unrelated overrun.
Treating it as a discretionary top-up fund for scope additions instead of a risk reserve. Once contingency is spent on wants rather than risks, there is nothing left when a concealed condition or price escalation actually happens.
