# Variation Orders in a Fit-Out

> A variation order is a written instruction that changes the agreed scope, cost or time of a fit-out contract. A variation costs more than the item it touches because it also disturbs the programme, forces services to be re-coordinated, wastes work already done and may require re-procurement. The same change costs far less before design freeze than after long-lead items are ordered.

## Why the price of a change is never just the item

A fit-out variation order usually starts small. A client asks for a different partition system on one floor, or a meeting room
moved to the other side of the floor, or a different light fitting in reception. It looks small.
The instinct is to ask what the item costs.

That is the wrong question. On a fit-out, an item is rarely priced alone,
because it sits inside a sequence: a design, a set of coordinated services,
an order, a delivery, an installation and a trade waiting behind it. A change
to the item disturbs each of those. **A contractor pricing a variation is
pricing the disturbance, of which the item is only a part.**

This is the misconception worth correcting. A variation is not a line added to a
bill. It is an interruption in a programme.

## What a variation is actually priced on

| Cost driver | What it means on site |
| --- | --- |
| The item itself | Material, fabrication and installation of the new or changed element |
| Programme | A later trade is held, or the completion date moves, with the running cost of both |
| Re-coordination | Services drawings redone to keep ducts, pipework, cabling and lighting from clashing |
| Wasted work | Anything already made or installed that must be removed, discarded or remade |
| Re-procurement | An item already ordered is cancelled or changed, sometimes with the supplier's charges |
| Management time | Revised drawings, approvals, sequencing and site supervision |

Some of these are visible and some are not. A client sees the price of a light
fitting. They do not see that the ceiling grid above that room was already set
out, or that the electrical containment behind it was installed to suit the old
layout. The cost of a change follows where the project **is**, not what the
change looks like.

## Why timing changes the cost so much

The same change costs different amounts at different moments, and the reason is
simple: the further the project has gone, the more is fixed around the thing
being changed.

- **Before design freeze:** the change is a revised drawing. Nothing is ordered.
- **After freeze, before ordering:** drawings and possibly approvals must be
  reissued, but no material is committed.
- **After long-lead items are ordered:** the order has to be cancelled,
  amended or accepted as surplus, and delivery dates move.
- **After installation:** finished work is removed, the trades that followed
  may have to be recalled, and the area is disrupted a second time.

Programme-critical items, such as partition systems, joinery, specified lighting
and terminal equipment, are the ones most exposed, because they are made to
order. The reasoning behind releasing them early, and the trade-off, is set out
in [where the time actually goes in an office fit-out programme](/blog/office-fit-out-programme-where-time-is-lost).

## How variations arise

Not all variations come from the client changing their mind, and treating them
as if they do sours the relationship. Three sources are worth separating.

**Client changes.** A new requirement, a different headcount, a revised
brand direction. These are legitimate, and they are the client's to decide, at
the client's cost.

**Site conditions.** A slab that is not as the drawing showed, a shaft that is
narrower than assumed, an existing service that was not on the record. Whether
these are a variation depends on what the contract says about existing
conditions and surveys, and it should be read before work begins.

**Design gaps.** Something that was needed but not drawn: a services clash
found late, an omitted interface between two systems. Who carries the cost
depends on who was responsible for that design under the contract, and this is
where disputes are most heated.

Separating these three at the moment a change is raised, and recording which it
is, prevents an argument about cause from being fought later against a bill.

## What a fit-out variation order should contain

A variation is only as useful as its record. At minimum:

- **A reference and date**, so it can be found and sequenced.
- **A description of the change**, with the drawing or specification it
  affects, in words that a person who was not on site can follow.
- **Which of the three sources it comes from**: client change, site
  condition or design gap.
- **The cost effect**, stated as an addition or omission, with the basis of
  pricing shown.
- **The time effect**, stated even if the answer is "none," and which
  activities it touches.
- **The approver**, by name and authority, and the date of approval.
- **A statement that work on the change begins only after approval.**

That last line matters more than the others. A variation approved after the
work is done is not a control; it is a receipt.

## Why verbal instructions cause the most disputes

Site is fast. A client representative walks the floor, likes something,
and asks the foreman to change it. The foreman agrees, because refusing feels
obstructive. The work is done. Weeks later, a variation arrives with a price and
a date, and the client's finance team says nobody approved it.

Both sides may be acting in good faith. The client remembers making a
suggestion; the contractor remembers receiving an instruction. Whether a verbal
instruction gives rise to extra payment depends on the contract and on the
facts, and the general position under the **Indian Contract Act, 1872** is that
agreements are given effect according to what the parties agreed and can be
shown to have agreed. That is precisely why a written record is the practical
answer, not because verbal instructions are meaningless, but because they cannot
be reliably proven or priced.

The discipline is unglamorous: **nothing outside scope starts until it is written
and approved.** A short form, signed the same day, is enough.

## How contract structure changes who carries the risk

The contract structure does not remove variations, but it changes who carries
which kind of risk.

Under a lump-sum, turnkey arrangement, the contractor prices a defined scope and
generally takes the risk of quantities and coordination within it. What
falls outside that scope is a variation. Under an item-rate arrangement,
the client generally carries more of the measurement risk, because the final
cost follows the quantities actually built. The full comparison is in the
[turnkey vs item-rate fit-out contracts](/compare/turnkey-vs-item-rate-fit-out-contract) page.

Neither is safer by label. What decides the outcome is how the scope is defined,
how the variation clause is worded, and how design responsibility is allocated.
An unclear scope under either structure produces variations; a clear one under
either produces few.

## Common mistakes

- **Approving after the fact.** The record is created once the work is done,
  so there is nothing left to decide.
- **Pricing only the item.** A client accepts a quotation for the fitting and
  is later surprised by the programme and coordination effect.
- **Freezing too late.** Design decisions are left open while long-lead items
  are ordered, so any change lands after ordering.
- **Skipping the site survey.** Existing conditions are assumed, and the
  difference is later called a variation.
- **Mixing causes.** A design gap is presented as a client change, or the
  reverse, and the argument becomes about blame rather than cost.
- **No time statement.** A variation is priced but its effect on the
  completion date is left blank.
- **Small changes not tracked.** Individually minor, cumulatively large, and
  nobody has the total.

## What to ask

- What is the variation procedure, and who is authorised to approve one?
- Is there a design freeze date, and what is the process for changes after it?
- Which items are already ordered, and what would a change to them involve?
- Does the price of a variation show the cost effect and the time effect
  separately?
- Who carries the risk of existing site conditions, and has a survey been
  done?
- Is there a running log of approved variations and their total?

A contractor who can answer these has a system. One who says "we will sort it
out as we go" has left the answer to be decided by whoever is angrier.

## Standards referenced

Contract formation and variation by agreement under the **Indian Contract Act,
1872**; building services provisions in **NBC 2016, Part 8**, relevant where a
change affects the coordination of services. The legal effect of any variation,
instruction or clause depends on the specific contract and must be confirmed
with the client's legal adviser. Technical effects of a change on services or
structure must be confirmed by the project's engineer.

## Frequently asked questions

### What is a variation order in a fit-out?

It is a written instruction, agreed by both sides, that adds, omits or alters something in the agreed scope of works. A proper one states what is changing, what it does to the cost, what it does to the programme, and who has approved it. Without those elements it is an instruction, not a record, and that gap is where most disputes begin.

### Why does a small change cost more than the item itself?

Because the item is only part of what moves. A change can hold up a trade that follows, require services drawings to be redone, leave completed work to be removed and re-made, or force an item to be re-ordered. Each of those has a cost and a duration, and a contractor pricing the change is pricing all of them, not just the material.

### Why is it cheaper to change things before design freeze?

Before freeze, a change is an edit to a drawing. After freeze, it may mean an order already placed, a fabricator already working and installation partly done. The cost of a change rises at each of those stages, which is why decisions that are still open should be closed early, and why long-lead items are best released only against settled information.

### Are verbal instructions on site binding?

They may be relied upon in a dispute, but they are hard to prove, hard to price and easy to remember differently. Whether a verbal instruction creates a right to extra payment depends on the contract and on the facts, which is exactly the uncertainty a written record removes. The simple discipline is that nothing beyond scope is started until the variation is approved in writing.

### Who carries the risk of a variation?

That depends on the contract structure. Under a lump-sum turnkey arrangement, the contractor generally carries the risk of quantity and coordination within the defined scope, while changes to scope are variations. Under item-rate, the client generally carries more measurement risk. The wording of the contract, not a label, decides, so read the variation clause before signing.

### Can variations be avoided altogether?

Not entirely, because site conditions and client needs do change. They can be reduced by a complete brief, a coordinated design before procurement, a clear freeze date and a survey of existing conditions. What matters is that each change is visible, priced and approved before work proceeds, so that the total is never a surprise at the end.
