Construction Stages of an Apartment: What to Confirm Before Each Payment

Anyone who books a flat before it is finished ends up paying in instalments that track the building's progress. Once a buyer knows what each stage looks like, a demand letter becomes a claim to be checked and not an order. This guide follows a Bangalore apartment tower from groundwork to handover and lists what to confirm before each payment.

Three Groups of Work

Developers label stages in their own ways, but nearly every high-rise follows one sequence of seven stages. They fall into three groups: work at and below ground, the structure with its walls, and the services and fit-out that make a flat liveable.

Group One: At and Below Ground

The first two stages prepare the land and carry the load of the tower into the earth.

Approvals and site preparation

Work starts only after the authority sanctions the building plan. Crews then clear and level the plot, sloping it so rainwater runs off. Soil tests settle the foundation's type and depth.

Excavation, foundation and basement

Diggers go down to foundation level and to the full depth of any basements. Basements receive waterproofing, drains and pumps, a real concern on low plots that flood in heavy rain. The foundation's design follows the soil and how tall the tower will be.

Parking is fixed here too, whether in a basement, below stilts, over a podium or as mechanical stacks. Every extra underground level adds time.

Group Two: Structure and Walls

This group is the one most payment plans are built around, since its progress is easy to see from outside.

The structural frame

Every finished slab is something a buyer can count. Bangalore sites use three main methods:

• RCC frame: columns, beams and slabs first, then walls built of blocks
• Mivan: aluminium shuttering into which walls and slabs are poured as one concrete structure
• Precast: wall and slab panels cast in a factory and joined at the site

Method affects speed as well as the walls themselves. A wall poured in concrete is tougher to alter than a block wall, so look for the method in the project specifications.

Walls and plaster

Masonry starts on the lower floors after a few slabs are done. Plastering inside and out comes next, and bathrooms, balconies and the terrace are waterproofed. Rooms can now be measured against the floor plan.

Group Three: Services and Fit-Out

The last three stages turn a concrete shell into a home and a complete project.

Mechanical, electrical and plumbing work

MEP, which stands for the mechanical, electrical and plumbing services, covers conduits for wiring, plumbing and sewer lines, fire-fighting lines, lifts and basement air handling. It proceeds in parallel with plastering. Finishes hide nearly all of it, so mistakes are expensive to fix later.

Finishing

Flooring, wall tiles, doors, windows, paint, sanitary fittings and electrical switches are what a buyer actually sees. This is the labour-heavy stage, with trades following each other in a strict order. Each material should match the list annexed to the agreement.

External works and the occupancy certificate

Roads, planting, the clubhouse, a sewage treatment plant, power and water complete the campus. The developer then seeks the occupancy certificate from the competent authority, and RERA also makes the developer responsible for passing it on to buyers.

What the Law Gives a Buyer on Schedule

RERA, the 2016 law governing real estate projects, requires the agreement for sale to say when and how payments fall due. Section 11(3) obliges the developer to hand over a stage-wise completion timetable at booking, along with plans for water supply, sanitation and power.

The same timetable appears in section 19(2) among a buyer's entitlements, so no reason is needed to ask for it. A developer who delays it deserves a follow-up.

How Instalments Follow the Work

Each developer chooses its own shares, so the agreement holds the exact plan. The usual pattern is:

• Booking and agreement: a booking amount, then an instalment when the signed agreement is registered
• Foundation and basement: an instalment after the foundation or the first basement slab is finished
• Frame: instalments against named floor slabs, and the slab billed ought to rise in your own tower
• Walls, plaster and MEP: an instalment on masonry or plaster, with your floor included where the plan says so
• Finishing: payment on floors or internal finishes, with materials matching the specification
• Handover: the closing amount when possession is offered, together with delivery of the occupancy certificate

Section 13 limits what a developer can take before the paperwork is complete: an advance or application fee of at most 10% of the price, until the written agreement is signed and registered. A buyer who pays late owes interest under section 19.

Banks generally copy the same milestones, releasing a tranche on each demand letter. Across these years, the EMI calculator shows what the interest adds up to.

Proving a Milestone

Each demand letter points to a milestone that the building has either reached or not. Three checks settle the question:

• Read the developer's quarterly update on the state RERA portal
• Visit the site, count the floors and keep dated photographs taken from one vantage point
• Ask the lender, whose engineer normally inspects before each release of money

The update also lists flats booked and approvals pending since the commencement certificate. A status that does not change for several quarters shows slow work. If a milestone is billed ahead of progress, send the developer a written query.

RERA also restricts how the developer uses buyers' money. Seventy per cent of it must stay in a separate account that is reserved for land and building costs. Withdrawals have to follow the work done, and an engineer, an architect and a chartered accountant must certify that figure.

Defects and Changes After Handover

Because foundations, frames and services are hidden when a buyer moves in, structure should be inspected on site visits and finishes at the inspection before handover. Each has its own moment.

Under section 14(3), a defect in the building's structure or its finish work that turns up in the first five years after possession is the developer's to repair at no cost, in thirty days. If the developer does nothing, compensation follows.

Section 14 further requires the project to match its sanctioned plans and specifications. A flat can be altered only with its buyer's consent, and changes to other buildings or shared areas need written agreement from two thirds of the buyers.

Ask Before You Book

Take these questions to the sales team and check the replies against the agreement and the RERA record:

• Which construction method is used, and what the internal walls are made of
• How many basement levels exist, and where the water goes
• What triggers each instalment, and whether it applies to your tower
• What the schedule promises for each stage
• How far the site has progressed, per the newest quarterly update

Anyone looking at new projects in Bangalore at different stages should set progress beside price and location. It is a plain measure of the distance to handover.
