Sample PRDT AI Renovation Quotation Check

Mr T. — HDB Resale (4-Room), 93 sqm (approx. 1,001 sqft), 3 bedrooms, 2 bathrooms. Intended scope: Kitchen, Bathrooms, Flooring, Painting. One quotation uploaded for review.

This check reviews the contents of the uploaded document against PRDT's indicative reference ranges only. It does not assess contractor quality, workmanship or trustworthiness.

The quotation's stated total of $30,700 sits within PRDT's overall indicative range of $26,000–$40,500 for this scope. GST is not clearly stated on the document — if added at 9% on top, the estimated total would be approximately $33,460, which still sits within the range, but this should be confirmed directly with the contractor. Kitchen carpentry is priced as a $13,800 lump sum that sits above PRDT's $8,500–$13,000 reference range; the document also states a separate per-foot rate for the quartz countertop without a run length, so this line cannot be fully broken down. Disposal and haulage were not found in the document. The payment schedule requests 90% of the contract value before completion, leaving a 10% retention.

Reference ranges are indicative only, assuming typical materials at each tier and normal site conditions. A figure above a range is not evidence of overcharging — it may reflect additional cabinetry, a different brand or hardware, or site-specific factors.

Kitchen, Bathrooms, Flooring and Painting — the homeowner's full intended scope — are all found in the document. Disposal and haulage, often required alongside kitchen and bathroom works, were not found in the document (see Section 8).

• •"Kitchen cabinets (laminate carcass, quartz countertop) — lump sum $13,800": the quartz countertop is separately stated at "$185 per foot run", but no run length is given, so this sub-rate cannot be checked against the $13,800 total.
• •"Vinyl / engineered flooring — $5,600": brand and grade not stated.
• •"Prices are nett": does not state whether GST is included in the $30,700 total.

• •Disposal & haulage — not found in the uploaded document. If required separately, PRDT's indicative range for a comparable scope is $500–$1,300.
• •Protection works for common corridor / lift — often required during renovation, not found in the document.
• •Post-renovation cleaning — not found in the document.

Document states: 30% booking · 40% on commencement · 20% on delivery of kitchen carpentry · 10% on completion.

90% of the contract value is payable before completion, leaving a 10% retention for rectification works — worth discussing with the contractor, not a legal conclusion. Common Singapore practice often keeps a larger completion-linked retention.

• • Is GST included in the $30,700 total, or payable on top?
• • What run length is used to calculate the $185/ft quartz countertop rate, and is it already inside the $13,800 lump sum?
• • What brand and grade of flooring is included at $5,600?
• • Are disposal and haulage included in the lump sum, or charged separately?
• • What site conditions or changes would trigger a variation order, and how would it be priced?
