A low construction quote feels like a win. But in most cases, it is the beginning of a series of costly surprises. Understanding how and why low quotes are structured helps you make a more informed decision.
How Low Quotes Are Typically Structured
- ▸Missing items: waterproofing, compound wall, external work left out
- ▸Underspecified materials: "M15 concrete" instead of M25
- ▸Low labour rates that change during construction
- ▸No warranty provisions
- ▸Open-ended clauses: "Materials as per availability"

The Escalation Pattern
Most low-quote projects follow this pattern: mobilization advance paid → contractor starts work → "surprise" scope additions appear → homeowner is committed financially and emotionally → final cost is 30–50% above original quote.
Hidden Costs That Are Commonly Omitted
- ▸SBC (Soil Bearing Capacity) testing
- ▸Anti-termite treatment
- ▸External drainage and RCC drain channels
- ▸Staircase and parapet walls
- ▸Overhead water tank (RCC or Sintex)
- ▸Sump construction
- ▸Electrical main panels and earthing
- ▸Plumbing overhead tank connection
How to Protect Yourself
Always insist on an itemized BOQ with specifications before signing. Have an independent engineer review the BOQ. Link all payments to milestone completion. Use a signed change order process for any scope additions.
FAQs
Is it ever safe to go with the lowest quote?
Yes, if the lowest quote is fully itemized, with all specifications, realistic quantities, and comparable scope to higher quotes. The problem is rarely price — it is scope completeness.
