KWANG Quote Doctor
Got a construction quote?
Is it a fair price?
We compare interior and construction quotes from other contractors against unit prices actually contracted in Indonesia, and tell you — free of charge — which items are high and what to check.


Real result
Here is what a review looks like
A real case: we reviewed a retaining-wall reinforcement quote of IDR 1.73 billion.
Negotiable amount identified · 3.5–6.4% of the quote
We found grounds to adjust the ready-mix concrete unit price and the backfill quantity, and confirmed the remaining trades were within range — so you negotiate only the items that matter.

How to use the result
Report to HQ with evidence
Item-by-item verdicts and a one-page English summary give you the evidence to answer “is this price right?”
Compare even with a single quote
Actual contracted prices become your benchmark. We can spot high items without a second quote.
Negotiate with target prices
You get target unit prices per item and a question list in English and Indonesian. Send it to the contractor as is.
We also review
Quotes your local team brought in
We compare contractor quotes collected by your local staff with actual contracted prices and identify inflated items — with the evidence, so management can verify what is hard to check directly.
Your own quote, before it goes out
We check formulas, totals, omissions and unusual unit prices in quotes prepared by your team. Remove client and site details and tell us only the region — unit prices vary by region, so that is all we need.

FAQ
Frequently asked questions
What kind of works do you review?
Office and retail interiors, fit-out, MEP works (mechanical, electrical and plumbing), factory and building construction, and civil works — from small jobs to large-scale factory projects. For large projects, we simply confirm the review scope with you first.
Can you review our own quote?
Yes. We check the formulas and totals of quotes prepared by your team and flag unusual unit prices. Remove client and site details and tell us only the region (unit prices vary by region).
Will the contractor know about the review?
No. KWANG does not contact the contractor, and you can hide the contractor’s name.
Which languages do you work in?
Quotes can be in English, Indonesian or Korean. Reports are delivered in English (or Korean on request), and questions for the contractor come in Indonesian as well.
Do you need drawings?
We can review unit prices from the quote alone. Drawings or site photos make the quantity check more accurate.
