How to Compare Office Interior Quotations the Right Way

Getting three quotations does not automatically mean you have compared the market. In office interiors, most quotation comparisons fail for one reason: the scope is not aligned. One vendor prices complete HVAC and furniture. Another prices only interiors and calls the rest "extra as applicable." A third gives the best-looking PDF but hides half the details under lump-sum heads.

So the goal is not to compare three numbers. The goal is to compare three scopes.

The Wrong Way to Compare Quotations

The fastest wrong method: open all three proposals, check final amount, shortlist the cheapest two, negotiate price. That is how expensive surprises are created.

The Right Way: Compare in This Order

1. 1Scope completeness
2. 2Specification quality
3. 3Quantity logic
4. 4Exclusions
5. 5Commercial terms
6. 6Total price

Yes, total price comes last.

Step 1: Normalise the Scope

Create one common checklist and test each quotation against it. Your checklist should include:

• Design scope
• Civil works
• Flooring
• False ceiling
• Partitions and glazing
• Electrical
• HVAC
• Fire safety
• IT / network / AV
• Furniture
• Branding / signage
• Testing and handover

Step 2: Identify Where Each Quote Is Stronger or Weaker

• Who has priced more items?
• Who is assuming a lower spec?
• Who has left MEP vague?
• Who has priced furniture properly?
• Who has hidden scope inside "provisional" language?

A higher quote is not always expensive. It may simply be more complete.

Step 3: Compare Specifications, Not Just Descriptions

"Meeting room partition" can mean very different things. Check whether vendors are pricing standard or acoustic glass, standard or premium laminate, standard or branded hardware, task lighting only or layered lighting, basic workstations or higher-grade ergonomic systems. If the specification assumptions differ, the numbers cannot be compared directly.

Step 4: Review Exclusions Carefully

The commercial trap in many fit-out quotations is the exclusion section. Look for exclusions around:

• HVAC
• Electrical fixtures
• AV
• Chairs and loose furniture
• Access control
• Statutory approvals
• Demolition and debris
• After-hours execution
• Taxes
• Delivery and installation

Sometimes the "best" quote is only better because it excluded the riskiest scope.

Step 5: Review Commercial Terms

• Advance percentage
• Stage billing
• Retention
• Change-order rules
• Timeline commitment
• Delay handling
• Defect liability period
• Testing and handover responsibility

A Simple Comparison Framework

What to Do When One Quote Is Much Lower

• Which work heads are not included?
• What specs have been downgraded?
• What assumptions are different?
• What has been priced as provisional?
• What will be billed later as variation?

What to Do When One Quote Is Much Higher

A high quote is not automatically wrong either. Ask: is this vendor including more complete MEP? Are they using stronger materials? Are they pricing logistics and compliance more realistically? Have they included better furniture and accessories? Sometimes the highest quote is the only one that actually understood the project.

A Practical Decision Rule

Award based on: aligned scope, acceptable spec, transparent BOQ, fair commercial structure, and confidence in execution. Not the prettiest presentation, the cheapest total, or the most persuasive salesperson.

FAQs

How many office interior quotations should I compare?

Three to five properly itemised quotations are usually enough, provided the scope is aligned.

What is the biggest mistake in quote comparison?

Comparing final totals before comparing inclusions and exclusions.

Can the cheapest quote still be the best?

Yes, but only after you confirm it includes the same scope and specification as the others.
