When people plan a house, most of the time goes into the front elevation, the kitchen and the tiles. The foundation and the steel get a few minutes, usually when the contractor asks for money for them. That is the wrong way round, because those are the parts you cannot change once the concrete is poured.
These are the questions worth settling before work starts on any house in Multan, whoever builds it.
Has the soil been tested?
Soil around Multan is mostly river-laid silt and sand, and it changes from one area to the next. A soil investigation tells the structural engineer how much load the ground can carry and how deep the water table is. Some builders skip it for a single-storey house. For a double-storey house, a basement, or a plot on low-lying land or near a canal, it is money well spent.
What kind of foundation, and why?
Most houses here sit on strip or isolated footings. A raft foundation spreads the load over the whole plot and is used where the soil is weak or the building is heavy. Neither is automatically better. The choice should come from the soil report and the structural drawings, and your engineer should be able to explain it in plain words.
Which steel, and from where?
For columns, beams and slabs, structural engineers in Pakistan commonly specify Grade 60 deformed bars, which have a higher yield strength than Grade 40. Whatever grade the drawings call for, ask for the mill test certificate, buy from a known mill and check the markings on the bars when they arrive. Re-rolled bars of unknown origin are cheaper for a reason.
How strong is the concrete, and how is it cured?
The drawings should state the concrete strength. On site, that strength depends on the mix, the amount of water added and the curing. Ask whether test cubes will be taken, and make sure slabs, beams and columns are kept wet for at least seven days after the pour. In a Multan summer, concrete that dries out in the first few days never reaches the strength it was designed for.
Is the steel detailed for earthquakes?
Multan is not in the highest seismic zone, but the Building Code of Pakistan still applies here. In practice that means closer stirrups near the ends of beams and columns, stirrup hooks bent to 135 degrees rather than 90, proper lap lengths, and bars that run continuously through beam and column joints. These details add little to the cost and make a real difference to how a frame behaves when the ground shakes.
What about salt and damp?
Salty ground (kallar) is common in South Punjab, and it slowly eats into plaster and brickwork from the bottom up. A proper damp-proof course at plinth level, good bricks for the lower courses and anti-termite treatment under the floor are basic protection. All three are hard to add later.
Questions to ask before you sign
- Will a soil test be done, and who reads the report?
- Who is the structural engineer, and can I see the drawings?
- Which steel grade and which mill? Will I get the test certificate?
- What concrete strength is specified, and how will curing be done?
- How are stirrups and joints detailed?
- Where is the damp-proof course, and what is it made of?
- Who checks the steel before each pour?
