Quick answer: a typical house moves through 12 stages: site preparation, foundation, plinth, columns and slabs, masonry, services rough-in, plaster, waterproofing, flooring, doors and windows, painting, and fixtures and handover. Buy materials for the stage you are about to start, not for the whole house, and tie each purchase to the approved drawing, specification and delivery slot.
The order matters because many stages hide the previous one. Concrete buries reinforcement, plaster buries pipes and conduits, and tiles bury waterproofing. That is why testing and recording before you close a stage is part of the schedule, not an extra.
Before You Dig: Drawings, Approvals and the First BOQ
Before stage 1 the project needs approved architectural and structural drawings, the required local approvals and a soil or bearing-capacity report where the engineer needs one. Build the first BOQ from those drawings and set the purchase lots and required-on-site dates.
The construction material BOQ guide shows how to link every material line to a drawing revision, and the quotation comparison guide shows how to compare offers on the same basis.
Foundation and Plinth: Where Errors Get Buried
Foundation work uses concrete, reinforcement and formwork that cannot be inspected once poured. Confirm the concrete grade, exposure and mix (M15, M20 and M25 concrete mix guide), the reinforcement grade and diameters (Fe 500 vs Fe 500D vs Fe 550D guide), and the cover blocks before every pour.
Plinth work adds filling, the DPC and anti-termite treatment. Compact the fill, check levels and keep the DPC continuous. Buy cement in quantities you can store dry and use in sequence; the cement bags for a 1000 sq ft house guide gives a whole-house cross-check.
Superstructure: Columns, Beams and Slabs
This stage is the most cost-sensitive and the least forgiving. Choose between RMC and site mix using the ready-mix vs site-mix guide, inspect reinforcement and formwork before every pour, and cast cubes at the sampling frequency in the quality plan.
IS 456 gives minimum periods before formwork and props come off, and the engineer confirms them for your job. Curing after the pour is typically at least 7 days for OPC and longer, around 10 days, for blended cements or in hot dry weather.
Masonry, Plaster and Services: Why the Order Matters
Calculate bricks and mortar with the brick quantity calculator guide and choose plastering sand from the river sand vs M-sand vs P-sand guide. Conduits, cables and pipes go in before plaster, and each plumbing line should be pressure-tested before chases are closed.
Check pipe systems and cable sizes against the CPVC vs UPVC vs PVC pipes guide and the electrical wire size guide, and photograph concealed routes before they disappear.
Waterproofing, Flooring and Doors and Windows
Complete and test waterproofing before finishes: see the terrace waterproofing guide and the bathroom waterproofing cost guide. Order tiles from a compatible batch using the tile quantity calculator guide, and take door and window sizes from the actual openings.
Frames are often fixed at the masonry stage and shutters and hardware later, once the rough work is finished, so they are not damaged by plaster and painting.
Painting, Fixtures and Handover
Paint after plaster is cured and dry and leaks are fixed; use the paint quantity calculator guide for litres and coats. Fix sanitaryware, taps, switches and lights after tiling and painting, and test each system.
At handover, collect as-built drawings, test records, warranties, invoices and product manuals, and keep labelled spare tiles and paint for repairs.
Buying Timeline: Order-By Date vs Required-on-Site Date
Work back from the date each stage starts. Include approval and quotation time, supplier lead time, transit and inspection, and a buffer. The order-by date is when you must place the order; the required-on-site date is when you need it in hand. Confusing the two is the usual source of delays.
Buying too early is a risk as well: cement absorbs moisture, steel rusts and fittings get lost or damaged. See the guide to buying construction materials in Delhi and Mumbai for site-access and seasonal planning.
Buy Now vs Buy Later
| Material | Buy close to | Why not much earlier |
|---|---|---|
| Cement | The stage that uses it | Moisture and storage life |
| Reinforcement steel | Approval of the bar bending schedule and pour date | Rust, yard space and mixed diameters |
| Tiles and stone | Approved layout and finished rough-in | Breakage, batch changes and theft |
| Paint | Just before painting | Storage, shade mismatch and spoilage |
| Sanitaryware and fittings | After tiling and waterproofing | Damage and theft |
| Door and window frames | Masonry stage, after site measurement | Swelling, warping and damage |
Do these checks on site
- List the 12 stages with start dates from the contractor's programme.
- Attach each material line in the BOQ to the stage that uses it.
- Set an order-by date and a required-on-site date for each purchase lot.
- Approve samples, drawings and specifications before the order-by date.
- Buy for the next stage, not the whole house.
- Inspect, test and record each stage before closing it.
- Photograph concealed work, including reinforcement, pipes and waterproofing.
- Reconcile ordered, delivered and used quantities weekly.

Checks people skip and then pay for
- Do not skip the testing step to catch up with the schedule; retesting after closure costs far more.
- Give every stage a named person who signs off before the next stage starts.
- Keep a dated photo log of each hidden layer.
- Confirm site storage before an early bulk delivery.
- Use the rainy and hot months deliberately: plan pours, painting and waterproofing around the weather.
- Order finishing materials only after the final finish selection is fixed.
How This Plays Out on Madoverbuildings (MOB)
Madoverbuildings (MOB) can support stage-by-stage sourcing of structural, plumbing, electrical, finishing and interior materials. Explore relevant construction materials on MOB, submit a mixed list through Magic Quote, or use an RFQ for project quantities. The architect, structural engineer and contractor remain responsible for design, sequence, testing and acceptance.
Frequently Asked Questions
What are the stages of house construction?
Site preparation and layout, foundation, plinth and DPC, columns beams and slab, masonry, services rough-in, plastering, waterproofing, flooring, doors and windows, painting, and fixtures and handover.
How long does each stage take?
It depends on the size, design, weather, labour and approvals. The contractor's programme should give durations, and concrete curing and formwork stripping periods set minimum gaps.
When should I buy cement and steel?
Close to the stage that uses them, with steel ordered after the bar bending schedule is approved. Buying too early risks moisture damage to cement and rust on steel.
When can formwork be removed?
IS 456 gives minimum periods, for example 16 to 24 hours for vertical forms and 7 to 14 days for props to slabs depending on span. The engineer confirms them for your project.
Should plumbing and electrical work be done before plastering?
Yes, conduits, cables and pipes are usually installed and tested before plastering, and the concealed routes are photographed for later reference.
Should waterproofing be done before tiling?
Yes. Apply and test waterproofing, add the protection layer, and only then lay tiles or screed.
When should I buy paint and sanitaryware?
Paint just before painting, from one batch, and sanitaryware after tiling and waterproofing are complete, to avoid damage and mismatch.
What documents should I collect at handover?
As-built drawings, test records, warranties, invoices, product manuals and a schedule of spare tiles and paint.
