How to Choose a Construction Contractor in Bangalore

Almost every construction horror story in Bangalore starts the same way: a quotation that looked slightly cheaper than the others. Here is how to evaluate a contractor properly, in the order the checks actually matter.

1. Ask for three documents before anything else

Before you discuss design, budget or timelines, ask for these three things. A serious contractor will send them the same day. Anyone who hesitates has told you something important.

• GST registration certificate. It confirms the business exists as a taxable entity and that you will get a proper invoice you can rely on later.
• Two completion certificates from the last 24 months. Not photographs — documents, with client names you are allowed to call.
• A sample bill of quantities from a completed project. This tells you more about a contractor than any brochure. You are checking whether they quote in specifications or in vague lump sums.

2. Read the quotation for what is missing, not what is listed

Anyone can list what is included. The money is in the exclusions. Go through a quotation hunting specifically for:

• Whether a brand and grade is named against each material, or just a category. "Vitrified tiles" is not a specification. "600x600 vitrified tile, brand X, ₹85/sq.ft allowance" is.
• Whether excavation, soil disposal, water and electricity connections during construction, and scaffolding are priced or assumed.
• Whether statutory fees, plan sanction charges and betterment charges are inside or outside the number.
• Whether the rate is per square foot of built-up area, and critically, how built-up area is measured — balconies, staircases, terraces and parking are counted differently by different contractors, and the difference can be 8% of your total.

A quote that is 10% cheaper but excludes four items the other quotes include is not cheaper. It is incomplete.

3. Insist on milestone payments, never calendar payments

This is the single most protective clause in your contract. Payments should be released against verified completed work — mobilisation, foundation, each slab, blockwork, plastering, finishing, handover — and never against a date on a calendar.

Calendar-based payment transfers all schedule risk onto you. Milestone-based payment keeps it where it belongs. If a contractor resists this, understand clearly what they are asking you to fund.

4. Check that the structural design is done by a licensed consultant

Ask who is doing the structural design and ask to see their licence. In Bengaluru this matters more than most people realise — soil conditions vary substantially across the city, and a design copied from another plot is a genuine risk rather than a theoretical one.

A contractor who does structural design "in-house, informally" is telling you they are prepared to carry a risk on your behalf that they cannot actually insure.

5. Visit a live site, not a finished one

A completed project shows you the best day of a contractor's work. A live site shows you their normal one. When you visit, look at:

• Material storage. Is cement off the ground and covered? Is steel free of heavy rust? Is sand screened?
• Site housekeeping. Disorder in the yard reliably predicts disorder in the schedule.
• Safety. Helmets, edge protection, proper scaffolding. A contractor careless with worker safety is careless generally.
• Who is supervising. Ask how many sites that supervisor is running. If the answer is more than three, your project will be managed by WhatsApp.

6. Ask the three questions that actually reveal something

Most interview questions get rehearsed answers. These three do not:

1. "Tell me about a project that went wrong and what you did." Everyone has one. A contractor who claims otherwise is either inexperienced or not being straight with you.
2. "What would make you refuse this project?" A contractor with standards has limits. One who will take anything will also promise anything.
3. "What is your contingency assumption, and what triggers it?" Listen for a number and a defined trigger. Vagueness here becomes a variation claim later.

7. Understand the waterproofing warranty specifically

In Bengaluru's monsoon, waterproofing is where money quietly disappears two years after handover. Ask for it as a separate written warranty, covering terrace, sunken slabs, balconies and all wet areas, with a stated duration and a named remedy.

"We do good waterproofing" is not a warranty. A signed document with a duration on it is.

8. Confirm who your single point of contact is

You want one named project manager with a phone number, and a written escalation path above them. Projects where the client has to relay information between an engineer, a supervisor and an owner are projects where information gets lost, and lost information becomes rework you pay for.

9. Have a lawyer read the contract

For a project costing tens of lakhs, spending a few thousand rupees on a contract review is obviously worth it, and almost nobody does it. Have your lawyer check specifically: the completion date and what happens if it slips, the variation-order procedure, the defect liability period, the termination clause, and the dispute resolution mechanism.

The short version

A good contractor makes their process legible to you. You should be able to see what you are buying, what it costs, when it will be done and what happens if it is not. Anything that resists being written down is a risk you are being asked to carry without being told.
