Your quotation is also a scope document
A renovation quotation should show what the contractor has agreed to supply, build, remove, coordinate and hand over. The final price only becomes meaningful when you understand the work behind it.
The Competition and Consumer Commission of Singapore says renovation prices should be transparent, accurate, clear and itemised, with mandatory charges stated from the outset. If a charge cannot be calculated in advance, its existence and an estimate should be disclosed before the contract is entered into.
What each section should help you understand
| Quotation section | Details to look for | Why it matters in a resale HDB |
|---|---|---|
| Site preparation and preliminaries | Protection, haulage, disposal, permits, temporary works and site coordination. | Building rules, access arrangements and the extent of protection can change the real cost of starting work. |
| Hacking and demolition | Exact areas and items to remove, disposal, making good, retained elements and exclusions. | Older finishes, built-ins and concealed conditions may only become clear as the existing work is opened up. |
| Masonry and wet works | Quantities, tile allowance, substrate preparation, waterproofing, screed, labour and finishing. | A simple per-area price may not explain the preparation or rectification required below the new finish. |
| Carpentry | Measurements, board and laminate specification, internal configuration, hardware, countertop and lighting. | Two similar-looking wardrobes can differ materially in internal storage, hardware and construction scope. |
| Electrical and lighting | Number and type of points, rewiring assumptions, fittings, testing and the Licensed Electrical Worker scope. | An older flat or a reconfigured layout may need more than relocating a few visible points. |
| Plumbing and sanitary works | Fixtures, pipe replacement or relocation, Licensed Plumber scope, testing and making good. | Changes to wet-area functions can affect cabinetry, waterproofing and the order of works. |
| Ceilings, painting and finishing | Areas included, surface preparation, repair assumptions, paint system, number of coats and access requirements. | Existing cracks, dampness or damaged surfaces may need treatment before a new finish is applied. |
| Allowances and optional items | Which values are fixed, estimated, provisional or excluded, and how upgrades are priced. | An allowance is not the same as a confirmed price for your final selection. |
How to compare quotations fairly
Give each firm the same floor plan, requested scope and known site information. Then compare the following fields line by line:
- What is included and excluded from each work item?
- What quantity or measurement is being priced?
- Which material, brand, model, thickness or hardware specification applies?
- Does the price include labour, delivery, disposal, installation, testing and making good?
- Which items are estimates or provisional sums rather than confirmed prices?
- Who is responsible for permits, regulated work and building submissions where required?
- How are changes priced and approved?
- What payment is due at each milestone?
- What happens if the site condition requires a different solution?
Itemised does not automatically mean fixed
An itemised quotation makes the scope easier to understand, but it cannot make every concealed condition visible before work starts. This is particularly relevant when existing carpentry, false ceilings, floor finishes or boxed-up services are being removed.
The quotation should distinguish confirmed work from assumptions and allowances. It should also explain how new information is reported, priced and approved. CCCS states that revisions or work-order variations should proceed only with the consumer's express agreement.
Variations should leave a clear trail
Before additional work begins, the variation should identify the change, why it is required, the price or pricing method, any effect on the schedule and the approval given. Verbal instructions are difficult to compare with the original scope later.
CASE explains that businesses under its renovation accreditation scheme use progressive payment schedules, clear pricing breakdowns and written agreement for variations. These are useful principles to discuss with any renovation firm, whether or not it participates in that scheme.
Match payments to visible progress
A payment schedule should state how much is due and what milestone triggers it. Avoid treating calendar dates alone as proof that a construction stage has been completed.
CASE describes progressive payment as payments collected in phases upon agreed milestones. The exact schedule should reflect the actual project and signed contract. Before releasing the final payment, review completion, outstanding defects and the agreed rectification process.
Questions to ask before you sign
- Can you mark every provisional, optional and excluded item?
- Which mandatory costs could still arise, and what estimate can be given now?
- Does the demolition scope include disposal and making good?
- What condition is assumed behind retained finishes and built-ins?
- Are electrical, plumbing and permit-related responsibilities identified?
- Which selections can change the price after confirmation?
- Will every variation require written approval before work proceeds?
- Are the payment milestones linked to defined stages of completion?
- What warranty and defect-rectification terms are written into the contract?
How Essentia presents the scope
Essentia Works provides an itemised quotation so you can see how the budget is distributed across the agreed work. Payments are arranged by project milestones, and mandatory costs known at quotation stage are included rather than held back as handover surprises.
For a resale HDB, we also separate what can be confirmed before construction from what may require verification after existing work is opened up. If the scope changes, we explain the reason, cost and renovation impact before proceeding.
