A beautiful home stands on strong foundations of planning and quality. If you are building on your Velammal Garden plot in the Padappai Oragadam belt, a clear checklist for quality checks at each construction stage will save time, money, and future repairs. Here is a simple, on-site guide you can follow along with your architect and contractor in Chennai.
Before You Start: Drawings, Permits, and Site Readiness
Good construction begins on paper. Ensure your sanctioned drawings and structural designs match site conditions and soil test data.
Must-do checks
- Confirm DTCP and RERA approvals are in place for the layout and your building plan aligns with local by-laws
- Verify soil investigation report and foundation type recommended by the structural engineer
- Cross-check column grid, setbacks, floor heights, and stair position on the ground with total station markings
- Set up a site diary to record daily progress, material receipts, slump tests, cube casting, and inspections
- Arrange safe material storage for cement, steel, and blocks with cover from Chennai’s coastal humidity
Stage 1: Excavation and PCC
This stage sets the reference for levels and load transfer. Accuracy now prevents costly rework later.
Quality checks
- Benchmarks fixed with respect to road level and plot corner stones
- Excavation depth as per drawing with proper sideslope or shoring in clayey soils around Padappai
- No loose soil at the base, spread and compact a 40 to 75 mm sand layer if specified
- Plain cement concrete (PCC) thickness and level checked with laser or water level
- Provide anti-termite treatment at the approved dosage before foundation concrete
What to record
- Photographs of excavation depth tape readings
- Concrete receipt, mix grade, and pour time noted in the site diary
Stage 2: Foundation and Footings
In the Oragadam industrial belt, varying soil pockets mean foundations must strictly follow structural designs.
Quality checks
- Reinforcement steel grade, diameter, spacing, and cover blocks as per bar bending schedule
- Reinforcement free of rust, oil, and mud; proper laps and bends maintained
- Formwork rigid and line or level checked before pour
- Concrete mix grade verified and slump tested on site; cube samples taken for 7 and 28 day strength
- Vibrators used uniformly to avoid honeycombing, starter bars placed true to grid for columns
Common issues to prevent
- Inadequate concrete cover leading to corrosion in coastal humidity
- Misaligned starter bars making columns eccentric
Stage 3: Columns, Plinth Beam, and Backfilling
Vertical accuracy and plinth integrity decide the stability of your frame.
Quality checks
- Column shutter plumb checked with spirit level from two directions
- Column sizes verified at multiple lifts, starter bars kept vertical
- Plinth beam reinforcement and stirrups checked for spacing and cover
- Backfilling done in layers with compaction, especially important before laying grade slab
- Provide termite reticulation pipe if planned, with accessible refill points
Tip for Chennai monsoons
- Create temporary surface drains to keep the site dry and avoid soil softening
Stage 4: Ground Floor Slab or Grade Slab
This is a service-heavy stage that needs coordination.
Quality checks
- Conduits for electrical, internet, and earthing placed before the pour
- Plumbing trenches and sleeves laid to slope with traps at the right locations
- Polyethylene sheet and reinforcement mesh properly lapped
- Expansion or contraction joints provided as per drawing
- Slab finish level checked with laser and cured for a minimum of 7 days
Stage 5: Superstructure Brickwork or Blockwork
Walls define spaces and service runs. Straightness and bonding are key.
Quality checks
- Use good quality blocks or wire-cut bricks with consistent size and soundness
- Mortar mix proportion controlled and mixed in batches, not by guesswork
- Mason line and plumb bob used every course for straightness and verticality
- Lintel and sunshade reinforcement checked; adequate bearing on walls ensured
- Door and window frames fixed plumb and protected during masonry
Chennai comfort note
- Plan cross-ventilation and window sizes to suit prevailing sea breeze and Padappai wind patterns
Stage 6: Roof Slab Shuttering and Reinforcement
Slabs and beams carry your home. Extra attention here avoids deflection and cracks.
Quality checks
- Shuttering tight and supported with proper props and bracings; no visible sags
- Beam and slab reinforcement verified against structural drawings, including negative bars at supports
- Electrical conduit and fan box positions finalised before pour
- Slump test, cube casting, and continuous curing planned
- Remove formwork only after recommended time and shore the slab if required
Stage 7: Waterproofing and Terrace Finishes
Waterproofing is your long-term shield against seepage, especially vital for Chennai’s rains.
Quality checks
- Bathroom sunken slabs waterproofed with approved chemicals and corner fillets
- Terrace waterproofing membrane or IPS with proper slope to drain points
- Water ponding test for 48 hours to confirm no leaks
- External walls receive a waterproof base coat before plaster
Stage 8: Plastering and External Finishes
Uniform plastering ensures good paint finish and weather protection.
Quality checks
- Surface cleaned and dampened before plaster
- Plaster mix proportion and thickness maintained
- Joints staggered and chicken mesh used at dissimilar material junctions
- Drip moulds formed on chajjas and balcony edges
- External surface primed with weatherproof primer
Stage 9: MEP Rough-ins and First Fix
Services should be invisible after finishing yet easy to maintain.
Quality checks
- Electrical point schedule matched with approved drawings and actual usage needs
- Conduits, junction boxes, and DB locations level and accessible
- Plumbing pressure test for water lines and air test for drainage lines
- Proper slopes in pipelines to avoid air locks and backflow
- Earthing pits, lightning arrestor, and SPD installation verified
Stage 10: Flooring, Carpentry, and Joinery
This is where the look and feel come alive.
Quality checks
- Screed laid level and cured before tile laying
- Tile selection and batch shade matched; grout lines straight and even
- Granite or engineered stone countertops properly supported and sealed
- Door shutters checked for warp and alignment; hardware fitted snugly
- Windows sealed against rain with approved sealants
Stage 11: Painting and Final Finishes
Healthy indoor air and durability depend on correct painting.
Quality checks
- Moisture readings acceptable before primer
- Putty applied thin and even, sanded between coats
- Low-VOC paints preferred for bedrooms and kids’ rooms
- Colour samples approved in natural light
- Metal surfaces receive anti-rust primer before enamel
Stage 12: Handover, Snag List, and Documentation
A thorough closeout sets you up for a worry-free stay.
Quality checks
- Full snag list covering seepage, cracks, door and window alignment, paint touch-ups, and service tests
- Test all circuits, MCBs, fixtures, and appliances
- Record as-built drawings for electrical and plumbing with valve locations
- Collect warranties for waterproofing, paints, tiles, pumps, and fixtures
- Maintain a maintenance schedule for the first year, including terrace re-coating if advised
Smart QA Habits for Homeowners
- Appoint a qualified site engineer or third-party auditor for fortnightly audits
- Use simple tools on site: spirit level, measuring tape, laser level, moisture meter
- Keep all delivery challans, test results, and photographs organised in a digital folder
- Align payments to milestones after quality sign-off, not just completion percentage
- Visit the site after heavy rains to check drainage and seepage points

FAQs: quality checks at each construction stage house construction chennai
What core tests should I insist on during concrete works in Chennai
Ask for slump tests at every pour and cube tests for 7 and 28 day strength. Ensure proper vibration, cover blocks, and curing. Record mix grade, supplier details, and pour time in your site diary.
How do I prevent bathroom and terrace leakages long term
Do sunken slab waterproofing with fillets, apply a tested membrane or crystalline system, and perform a 48 hour ponding test. Maintain correct slopes toward drains and seal all pipe penetrations before tiling.
Which documents are essential at handover
Collect as-built drawings, structural stability certificate, material warranties, test reports, and a snag closure report. Keep a maintenance guide for waterproofing, paint cycles, and MEP service intervals.
How should payments be tied to quality milestones
Link payments to inspection-based milestones such as foundation cast with test results, plinth completed and compacted, slab cast with cube reports, waterproofing passed ponding test, and final snag list closed.
