A house construction project in Chennai involves hundreds of individual decisions, approvals, material deliveries, quality checks, and financial milestones. Without a structured checklist, homeowners lose track of critical steps — missing a flood test before tiling, forgetting to get a structural stability certificate before the bank tranche, or overlooking TANGEDCO connection requirements before occupancy. The top construction company in Chennai follows a documented checklist at every stage. This guide gives you the same level of structured oversight for your own project.

AI-Managed Quality — 500+ Checkpoints
Book a Free Consultation — We Track Every Checkpoint for You
AI-QualityGuard manages 500+ quality checkpoints on every Buildiyo project — photographically documented, engineer-signed, and visible on your mobile app at every stage.
Every residential construction project in Chennai passes through eight distinct stages — each with its own critical checkpoints that must be verified and documented before the next stage begins. Missing a checkpoint at any stage creates problems that are exponentially more expensive to fix later.
1
Pre-Purchase Plot Assessment
Title verification, Encumbrance Certificate, Patta and Chitta, CMDA layout approval, road access, water table risk, and TANGEDCO feasibility — verified before any money changes hands.
Anti-termite treatment, excavation verification, reinforcement inspection, PCC layer, foundation concrete slump tests, cube samples, and 7-day wet curing before backfilling.
4
Structural Frame
Column and slab reinforcement checks, cover blocks, concrete grade verification, slump tests, cube samples, post-pour curing, and structural stability certificate for each completed floor.
5
Brickwork and Plaster
Fly ash brick quality check, mortar mix verification, lintel reinforcement, brick soaking, two-coat external plaster with waterproofing additive, and 14-day curing before painting.
6
Waterproofing
Terrace multi-layer system with 24-hour flood test, bathroom full-height coating with flood test before tiling, external wall render with waterproofing additive, DPC at plinth level — all photographically documented.
7
Finishing and MEP
Electrical first and second fix, plumbing first and second fix, flooring installation, door and window installation, interior painting — with earthing test and plumbing pressure test confirmed before sign-off.
8
Handover and Legal Completion
Snagging list completion, Completion Certificate from CMDA, TANGEDCO EB connection, CMWSSB water supply, all original documents handed over with post-construction warranty certificate.
Stage 1 — Pre-Purchase Plot Assessment Checklist
Before buying a plot for construction in Chennai, verify these items with a property lawyer and a structural engineer. The best builders in Chennai who offer pre-purchase plot assessments will check all of the following.
Title VerificationParent documents and chain of title — minimum 30 years. No encumbrance or mortgage on the plot confirmed with property lawyer.
Encumbrance Certificate (EC)Obtained from Sub-Registrar's office confirming no pending loans, mortgages, or legal disputes on the plot.
Patta and ChittaRevenue records confirming the plot is in the buyer's intended name with correct survey number — obtained from Taluk office.
CMDA Layout ApprovalConfirm the plot is in a CMDA-approved layout or has a conversion order from agricultural to residential use. Unapproved layouts cannot get building plan sanction or home loans.
FMB SketchField Measurement Book sketch from Survey Department confirming plot boundaries — used to verify the actual plot dimensions against the sale deed.
Road Access VerificationVerify the plot has legal access to a public road — landlocked plots cannot get building plan approval regardless of other documentation.
Water Table and Flood RiskCheck with neighbours and local CMDA flood map for low-lying or flood-prone classification — determines foundation type and adds to construction cost if waterlogged.
TANGEDCO EB FeasibilityConfirm TANGEDCO EB service connection is feasible for the plot — some plots in newly developed layouts face delays of 6–18 months for service connection.
Stage 2 — Design and Approval Checklist
Architectural Design
Soil investigation commissioned from NABL-certified geotechnical laboratory before design begins.
Architectural brief document prepared — number of rooms, Vastu preferences, budget, timeline — signed and agreed.
2D floor plan approved with all room dimensions, door and window positions, and furniture layout verified.
3D elevation design reviewed and approved by homeowner before CMDA submission — changes after submission cause delays.
Structural engineering drawing prepared by licensed structural engineer — foundation type, column sizing, reinforcement details.
MEP (electrical, plumbing, drainage) layout drawings prepared and coordinated with architectural plan.
Rainwater harvesting plan prepared — mandatory for all buildings in Tamil Nadu and submitted as part of CMDA application.
Application submitted with all required documents — title deed, EC, patta, FMB sketch, and architectural drawings.
Scrutiny fee paid and official receipt obtained and retained.
Planning Permission (PP) order received and verified against submitted drawings for accuracy.
PP order displayed at site before commencement of construction — a legal requirement before any excavation begins.
Financial and Contractual
Detailed BOQ prepared with material specifications and quantities — signed by both owner and builder before any work begins.
Construction agreement signed with milestone payment schedule — no large upfront payments, stage-wise billing only.
Construction loan (if applicable) sanctioned and first tranche disbursed against CMDA PP and BOQ.
Site insurance — workmen's compensation and site risk — confirmed before excavation commences.
Stage 3 — Foundation and Substructure Checklist
Plot demarcation and boundary marking verified against FMB sketch before excavation begins.
Anti-termite pre-construction soil treatment applied to sub-grade — mandatory before PCC casting.
Excavation depth and dimensions verified against structural drawing before reinforcement placement.
Foundation reinforcement — rebar spacing, diameter, cover blocks — inspected and photographed before concrete pour.
PCC (Plain Cement Concrete) layer cast and fully cured before column reinforcement placement begins.
Foundation concrete slump test conducted for each pour — results recorded and filed.
Concrete cube samples collected and sent to certified lab — 28-day compressive strength results obtained and filed.
Foundation curing: minimum 7 days wet curing before backfilling to achieve full structural strength.
Stage 4 — Structural Frame Checklist
Column reinforcement checked against structural drawing — bar diameter, spacing, stirrup pitch verified before shuttering.
Cover blocks (40mm minimum) placed on all reinforcement before concrete pour — prevents reinforcement corrosion.
Concrete grade verified — M20 or M25 per structural specification — no grade downgrades accepted.
Slump test for every pour: 50–75mm for RCC structural members — records retained for each pour.
Cube samples collected for 7-day and 28-day strength verification — results filed with project records.
Slab thickness checked with cover-meter or physical measurement at edges before concreting.
Post-pour curing: minimum 14 days continuous wet curing for columns and 21 days for slabs — no exceptions.
Structural stability certificate obtained from engineer for each completed floor — required for multi-storey and bank loan tranches.
Every Checkpoint Tracked and Photographed

From foundation reinforcement inspection to the 28-day cube test result to the final snagging list — every checkpoint documented with photographs and engineer sign-off before the next stage begins.
Brickwork using specified fly ash bricks — random sample crushing test verified for compressive strength.
Mortar mix ratio (1:5 cement:sand) verified on site — not left to the mason's discretion.
Lintel reinforcement placed over all door and window openings — dimension per structural drawing.
Bricks soaked in water for 6 hours before use — prevents excessive absorption of water from the mortar mix.
External plaster: 12–15mm two-coat system with waterproofing additive in the final coat.
Internal plaster: 12mm gypsum or cement plaster on all walls — applied to clean, well-bonded substrate.
External plaster wet-cured for 14 days minimum before any painting begins — plaster must be fully cured.
Stage 6 — Waterproofing Checklist
All waterproofing flood tests must be photographically documented with timestamped records — these photographs serve as warranty evidence and are required for bank tranche release in construction loans. No next-stage work proceeds until flood test records are filed.
BathroomsFull-height wall coating (min 1,800mm on shower walls) → floor crystalline coat → 24-hour flood test before tile adhesive is applied → epoxy grout on all tile joints.
External WallsWaterproofing additive in external render coat + elastomeric exterior paint — particularly critical on south-west facing walls exposed to monsoon rain.
Plinth DPCDamp-proof course (DPC) applied at plinth level before brickwork commences — prevents rising moisture from soil into the wall structure.
Stage 7 — Finishing and MEP Checklist
Electrical first-fix: conduit, junction boxes, and outlet positions per approved electrical drawing — verified before plastering.
Plumbing first-fix: concealed water supply and drainage lines per approved plumbing drawing — pressure-tested before walls are closed.
Flooring: adhesive mortar mixed to correct consistency, tiles laid with minimum 3mm grout joint and anti-lippage spacers.
Door and window frames plumb and level — checked with spirit level and confirmed before grouting or fixing.
Electrical second-fix: switches, sockets, DB board, earthing test conducted and certificate issued.
Plumbing second-fix: sanitary fittings, tap connections, geysers — pressure test conducted and results recorded.
Interior painting: putty → primer → two coats emulsion — no painting on uncured plaster or within 4 weeks of plastering.

Stage 8 — Handover and Legal Completion Checklist
Snagging list: systematic identification and rectification of all defects — door alignment, paint touch-ups, tile lippage, fitting leaks — before final payment is released.
Completion Certificate (CC) application filed with CMDA or municipal body — with all required completion documents.
CC received and original copy retained by owner — required for TANGEDCO connection, property registration, and loan closure.
TANGEDCO EB service connection: application filed with CC copy — timeline for connection varies by locality (4–12 weeks).
CMWSSB water supply connection: applied for and confirmed — separate from construction site water supply.
All original construction documents handed over: approved CMDA plan, soil test, structural drawing, material certificates, and warranty cards.
Maintenance manual: plumbing shutoffs, electrical panel layout, and waterproofing care instructions — provided in physical and digital format.
Post-construction warranty certificate from builder — covering structure, waterproofing, and MEP systems with clear rectification terms.

What is the most important document to check before buying a plot in Chennai?
The most critical document is the Encumbrance Certificate (EC) from the Sub-Registrar's office, which confirms there are no pending loans, mortgages, or legal disputes on the plot. Equally important is the CMDA layout approval status — properties in unapproved layouts cannot get building plan sanction or home loans from any scheduled bank.
When should the flood test be done during construction in Chennai?
There are two mandatory flood tests: the terrace waterproofing flood test (terrace ponded with 50mm water for 24 hours before protection screed is laid) and the bathroom waterproofing flood test (bathroom floor flooded for 24 hours before tile adhesive is applied). Both tests must be done before the next construction layer covers the waterproofing — they cannot be done retroactively after tiling.
What is a concrete cube test and why is it important?
A concrete cube test involves casting six 150mm concrete cubes from each batch of structural concrete poured on site. Three cubes are crushed at 7 days and three at 28 days — the results confirm that the concrete achieves the specified strength (M20 = 20 N/mm², M25 = 25 N/mm²). Failure to achieve specified strength indicates incorrect mix design or water-cement ratio — a structural safety issue that must be investigated immediately.
Is it mandatory to get a Completion Certificate in Chennai before moving in?
Legally, a Completion Certificate (CC) is required for lawful occupancy of a new building in Chennai. The CC is also required for TANGEDCO EB service connection, property registration in some cases, and closure of construction loans. Occupying a building without a CC makes the structure technically unauthorised and can create complications with property sale or loan refinancing in the future.
