A contractor’s confident answer is not enough when the project involves approvals, soil conditions, drainage, structural work and a large financial commitment. Use the questions below to verify who will be responsible, what the quotation actually includes, how the work will be controlled and whether past clients received the result they paid for.
Key takeaways
- Match the contractor’s legal name, GSTIN, PAN, address and bank-account name.
- Request licence copies, project approvals, insurance details and recent safety records.
- Compare quantities, specifications, exclusions, taxes, timelines and payment stages line by line.
- Put variations, delay remedies, retention, defects liability and payment terms in writing.
What should you ask on the first call and site meeting?
On the first call, ask which legal entity will sign the contract. Request its exact legal name, GSTIN, PAN, registered address and bank-account name, then perform GSTIN verification on the GST portal and confirm that all five details match.
A brand name or individual’s name on a visiting card does not establish who answers for defects, unpaid subcontractors or delayed work.
Ask these civil contractor questions about construction contractor experience:
- How many projects of the same type, scale and building system have you completed?
- Can you show comparable houses, warehouses, plotted developments, renovations or industrial buildings with similar excavation, structure, external works and services?
- Have you worked with similar access, soil, groundwater, slope and neighbouring properties?
- Which current projects are active, what are their committed completion dates, and who will supervise my site?
- Who prepares quantities, approves site instructions and authorises extra work?
| Evidence | What it proves | What it does not prove |
|---|---|---|
| Completed-project contacts | Finished-project performance | Current workload |
| Current-project contact | Present supervision and delivery | Final outcome |
| Photographs alone | Appearance at one moment | Cost, defects or reliability |
Finish by requesting two comparable completed-project contacts and one current-project contact. Ask each about final cost versus quotation, variation orders, water ingress, external works, bill delays and defect correction. A reference for a small house does not prove capability for a large development.
Which licences, approvals and safety records should you verify?
Start with jurisdiction, not a generic list of BBMP approval documents. Ask the contractor to identify the authority governing your exact site and provide its answer in writing.
| Authority | Possible jurisdiction | What to confirm |
|---|---|---|
| Airport-area planning authority | Sites affected by airport planning controls | Building permission, height restrictions and commencement permission |
| BDA | Bangalore Development Authority areas | Plan sanction, development permission and completion documents |
| Municipal body | City or town limits outside BBMP | Building-plan sanction, utilities and occupancy requirements |
| Gram panchayat | Rural areas near Devanahalli | Local permissions, land-use position and applicable higher-authority approvals |
A Devanahalli contractor should not promise a BBMP approval for a site governed by a gram panchayat, BDA or an airport-area authority. Require an approval schedule naming the authority, application, responsible party and present status for each item, including building-plan sanctions, commencement permissions, utility connections, environmental or fire approvals and completion documents.
For a marketed real-estate project, request the Karnataka RERA registration number and verify it on the RERA portal. Registration proves that the project was filed under the Act; it does not prove sound workmanship, fair pricing or timely delivery.
Ask for trade registrations, labour-compliance arrangements, worker induction records, wage and attendance records, accident-reporting procedure and a site safety plan. The plan must address excavation collapse, lifting, temporary electrical systems, work at height, personal protective equipment and public access.
Ask for worker’s compensation or employee-accident cover and public-liability or construction insurance, including policy limits and exclusions. Bengaluru construction approvals should have a named owner; Kashi Prayag Constructions can be assessed by the same written-responsibility checklist.
How do you compare civil-construction quotations line by line?
Ask whether each civil contractor quotation is a measured BOQ, a lump-sum scope or an approximate estimate before comparing the totals.
| Option | What it means | When it applies |
|---|---|---|
| Measured BOQ | Agreed rates multiplied by measured quantities | Uncertain quantities, such as excavation |
| Lump-sum contract | One price for a defined scope | Complete, stable design; exclusions shift risk to you |
| Cost-plus | Actual cost plus a fee, supported by open-book records | Requires close owner oversight |
| Design-and-build | One party carries design and construction responsibility | Use clear performance criteria and independent design review |
For a fair BOQ comparison, issue identical drawings, structural details and specifications. Mark every line included, excluded or provisional.
- Price separately: excavation, rock breaking, filling, compaction, surplus-soil disposal, retaining walls, stormwater drains, compound walls, roads, utility connections, testing, approvals, GST and reinstatement.
- Specify concrete, reinforcement steel, blocks, waterproofing, pipes, cables, tiles, doors and finishes by brand, grade, thickness and installation method.
- Confirm labour, scaffolding, formwork, equipment, pumping, transport, curing, cube testing, site supervision, protection and debris removal.
Ask what each provisional sum covers and what measurement, invoice or test evidence fixes its final value. Identify mobilisation charges, security deposits, retention, tax deductions and escalation clauses.
A lump-sum price is not fixed if drawings leave drainage, disposal or finishes undefined. For an item-rate contract, agree measurement rules and rates before work starts. Compare the final price only after these assumptions match.
What payment, programme and variation questions belong in the contract?
Ask for a construction timeline built around measurable construction payment milestones, not a promised completion month. It should sequence design approvals, long-lead procurement, excavation, foundations, structure, services, external development, testing and handover, with evidence for each milestone. Define extension rules for client changes, authority delays, severe weather and material shortages.
| Payment basis | Safer contract approach | Evidence |
|---|---|---|
| Running-account bill | Measured quantities completed | Joint measurement and engineer’s certificate |
| Stage payment | Pay after defined work is complete | Photos, test results and inspection record |
| Final payment | Release after contractual handover | As-built drawings, approvals and defect closure |
Write down the mobilisation advance, retention percentage, security deposit, GST treatment, tax deductions and final-payment trigger. Require the contractor to submit running-account bills, identify who measures quantities and name the person who certifies them. Link payment to verifiable work, not calendar dates.
Use a written variation order before executing extra quantities, substituted materials or design changes. Each record must state the reason, drawing or instruction number, quantity, rate, time effect and revised total.
Also define the material-price escalation formula, base date and any cap, plus responsibility for soil disposal, dewatering, temporary power and water, access roads, testing and authority fees.
For foundations, retaining structures and driveways, request the soil investigation report. It should show test locations, investigation method, groundwater observations and allowable-bearing or other design parameters. Confirm finished-floor levels, surface falls, outfalls and recharge or detention provisions so stormwater does not enter excavations.
What should you ask former clients before signing?
Speak with at least two owners of comparable completed projects and one client whose work is still underway. Ask whether each project met its contractual date, what caused every delay, and whether the final cost matched the original quotation.
Ask each reference:
- What was the largest variation? Request its written approval and reason.
- Did bills include measurements and supporting records? Did work stop during payment disputes?
- Did subcontractors or suppliers threaten unpaid claims?
- Can you inspect the work? Check water ingress, terrace and toilet waterproofing, drainage blockages, settlement, cracks, door and window operation, external paving and compound-wall quality.
- Were concrete and reinforcement records supplied, including the approved or design mix, cube-test results, reinforcement certificates, curing records, and responses to failed or late tests?
- Did the contractor coordinate electrical, plumbing, HVAC, glazing and finishing trades, or leave the owner to resolve clashes?
| Reference type | Compare | Contractor red flags |
|---|---|---|
| Completed project | Date, final cost, variations and defects | Unexplained overruns or unresolved leaks |
| Current project | Billing, coordination and payment disputes | Stopped work or unpaid-claim threats |
| Comparable scale | Structure and external works | References limited to smaller buildings |
Request the proposed defects liability period and a construction handover checklist covering structural and non-structural defects, waterproofing, drainage, settlement, doors, windows, electrical and plumbing tests, as-built drawings, warranties, manuals and authority documents. Keep retention or another remedy until closure.
Before work starts, reconcile architectural, structural and services drawings through a controlled revision register. Confirm the qualified structural designer issues revisions; informal changes can undermine approvals and load paths. These checks expose civil contractor references and contractor red flags before signing.
