From Empty Land to Keys in Hand: The 12-Step Journey

The 5–6 months of construction in step 8 is not one job but a chain of stages, and each has to be right before the next one covers it. The order below follows the stage certificates in the Uniform Building By-Laws, signed by the people who supervised and carried out each stage. The full list of forms and what the CCC needs is on the council approval page; this section is about what happens on your land, what gets checked, and what you have to decide.

1. 1

   Site survey, soil investigation and clearing

   Form G1: earthworks

   The land is surveyed and cleared. Selangor's by-laws require the ground under a building to be cleared of turf and vegetation, and ground filled with refuse or organic matter to be treated before anything is built on it. They also require the earthworks and foundations to be designed from the field and laboratory tests of a proper site investigation, started and supervised by a Professional Engineer with geotechnical experience. That soil report is what decides the foundation.

   Your decision: Confirm the boundary and site access with the surveyor, and talk to your neighbours before work starts. CIDB's homeowner guide asks for a neighbour's written consent where work involves a shared boundary, and says the build may not change the drainage onto their land.

2. 2

   Setting out

   Form G2: setting out

   The position of the house, its grid lines and floor levels are marked on the ground from the approved plan. Every column and wall is measured from these marks, so an error here moves the whole house.

   Your decision: Walk the pegs before digging starts. It is the last cheap moment to notice a porch, a gate or a tree in the wrong place.

3. 3

   Foundations: pad, strip, raft or piles

   Form G3: foundations

   The by-laws define a foundation as footings, a raft or piles that carry the building's loads into the soil. Pad footings sit under individual columns, strip footings run under walls, a raft spreads the load across one slab, and piles reach firmer ground when the top layer is too weak. The engineer chooses from the soil tests. The by-laws also force the question beside a drain: within a distance equal to the drain's depth, the foundation must sit at least 450 mm below the drain's invert unless the building is on piles. This is why deep piled foundations are listed on our packages page as a site-dependent cost, determined after a site visit.

   Your decision: The type is the engineer's call, not yours. Ask for a copy of the soil report and keep it with your house documents.

4. 4

   Ground beams, ground slab and damp-proofing

   Checked before every concrete pour

   Ground beams tie the foundations together and carry the ground-floor walls; the ground slab is cast over compacted fill. The by-laws require a damp-proof course in every wall at least 150 mm above the ground beside it. The Standard House Specification lists a soil anti-termite treatment. CIDB's guidance is that before concrete goes in, the mix, the size and spacing of the steel bars and the alignment are checked, and that concrete strength and soil test results are kept on record.

   Your decision: Ask when the pours are. The steel is visible for only a few hours; after that, the test records and photographs are the evidence.

5. 5

   Structural frame: columns, beams, first floor and stairs

   Form G4: structural

   In a reinforced-concrete frame, the columns and beams carry the loads and the walls between them only fill the gaps. In a load-bearing design, the walls themselves carry loads beyond their own weight. The by-laws accept either, designed to the Malaysian Standards MS EN 1992 for concrete or MS EN 1996 for masonry. In a two-storey house, this is when the first-floor slab and the staircase are cast.

   Your decision: Lock the layout now. Moving a wall, a staircase or a window after this point means redesign, and a load-bearing wall cannot simply be removed later.

6. 6

   Walls and roof

   Roof tested in the first heavy rain

   Brick or block walls go up between the columns; CIDB's materials guide lists clay brick, cement brick and IBS panels as common choices. The roof structure follows, then the covering: CIDB lists metal or zincalume sheet (light, heat-resistant) and clay tile (durable, good heat insulation) among the options. Once the roof is on, the house is dry and the trades inside can begin.

   Your decision: Roof covering and colour, and any provision for solar panels, belong in the specification before this stage, not after it.

7. 7

   M&E first fix: conduits and pipes

   Forms G5, G6 and G7: water, sanitary, electrical

   Conduits, cable runs, water pipes and sanitary pipes go into the walls and floors before plaster and ceilings close them in. CIDB's guidance is that these systems are inspected and tested before they are covered. Electrical work must be done by a contractor registered with the Energy Commission (Suruhanjaya Tenaga), and plumbing by a plumber certified by SPAN, the National Water Services Commission.

   Your decision: This is the biggest one. Mark every socket, switch, light point, water heater, air-conditioner point and outdoor tap on the plan now. Each one added after plastering means cutting a finished wall.

8. 8

   Plaster, waterproofing, ceiling and tiles

   Photograph the waterproofing before it is tiled

   Walls are plastered, wet areas (bathrooms, the wet kitchen, any flat roof) are waterproofed before they are tiled, ceilings go up, and floor and wall tiles are laid. Waterproofing is invisible once it is covered. CIDB suggests asking for the delivery orders, which show the brand and type of material actually used.

   Your decision: Tiles, sanitary fittings and finishes, chosen before this stage. CIDB's guide treats any change after the contract as additional work that needs a signed, written agreement of its scope, cost and time before it starts.

9. 9

   M&E second fix, doors, windows and paint

   Electrical Borang G and H (Energy Commission)

   Switches, sockets, lights, taps and sanitary ware are fitted, doors and windows are hung, and the house is painted. The wiring is tested before it is connected: CIDB's checklist covers the earth-leakage protection (ELCB), the earthing system, water pressure and leaks.

   Your decision: Door hardware, paint colours and light fittings.

10. 10

    External works, drainage and sewerage

    Forms G12 to G20, whichever apply

    The drains, the apron around the house, the septic tank or the sewer connection, the water line to the meter, the fence and the gate. Where there is no public sewer, a house uses an individual septic tank, which IWK describes as a two-chamber tank that only partly treats sewage. Where there is a sewer, the house connects to it through inspection chambers.

    Your decision: Gate, driveway and fence positions, which decide where the electricity and water meters can go. Fence and gate are outside our packages (see the packages page).

Conventional build or IBS?

CIDB defines an Industrialised Building System (IBS) as building with components made in a controlled environment, on site or in a factory, then transported, positioned and assembled. Its IBS Score measures how much of a building is built that way, out of 100: up to 50 points for the structure, 20 for the walls and 30 for other simplified construction solutions.

CIDB's contractor guide says IBS can save up to 50% of construction time, while the conventional method of brick, cement and site labour stays flexible and suits complex designs. CIDB's own IBS explainer names the trade-off: large components are costly to transport and need a planned route, which matters on a rural lot reached by a narrow road.

Neither is automatically better for a single house. Ask which method a quotation assumes, and whether your site access can take the lorries it needs.

A finished house is not a usable one until it is connected. Each utility has its own application, its own certificates and its own clock, which is why step 11 says to start them early.

Step 10 hands over the keys; this is the paperwork that should come with them. CIDB's handover guide and the 2024 construction regulations set out most of it. Keep a paper file and a scanned copy, as CIDB advises. The warranty page explains what happens after handover.

• ✓

  Keys and a handover letter

  A signed letter records the official handover date. Defect periods run from handover, so keep it.

• ✓

  The CCC

  The Certificate of Completion and Compliance, without which the house cannot legally be occupied. How it is issued is on the council approval page.

• ✓

  As-built drawings

  The plans as actually built, showing where the structure, pipes and cables really are. You will want them for any renovation.

• ✓

  Test reports

  Concrete cube tests, water pressure tests and the electrical tests (Borang G and H), as CIDB's handover guide lists.

• ✓

  Manuals and supplier warranties

  For the water heater, pumps, fans and anything else with a warranty of its own.

• ✓

  Defect period in writing

  CIDB says defect liability periods are typically 6 to 24 months depending on the contract. Report any defect in writing, with photographs, before it ends.

• ✓

  Safety and health file

  Under the 2024 regulations (regulation 14), the file holds information any later work on the house will need to be done safely. Ask for it.

• ✓

  A walk through the services

  Where the main switch, the distribution board and the main water valve are, and what needs regular maintenance.

• ✓

  Utility accounts in your name

  Electricity, water and, where applicable, the IWK sewerage account.

• ✓

  Assessment tax

  When a new building goes up, the council revises its valuation list and sends the owner a notice under section 144 of the Local Government Act 1976, which the owner may object to. MBPJ, for example, bills assessment twice a year, due by the end of February and the end of August.
