Buying TMT bars and cement for a small construction job

Steel and cement are the backbone of any construction job — and among its biggest material costs. For a small project such as a shop, an extra floor or a warehouse extension, buying them well means getting the right grade, the right quantity and material that is stored properly until it is used.

Get the quantities from your engineer

Do not estimate steel and cement by eye. Your structural engineer or contractor should give you:

• Steel quantity by diameter (for example 8 mm, 10 mm, 12 mm, 16 mm)
• Cement quantity in bags, and the type
• A schedule of when each lot is needed on site

Buying in stages as work progresses reduces storage problems and wastage.

TMT bars: what to specify

• Grade: your engineer will specify the grade (for example Fe 500 or Fe 500D). Buy exactly what is specified.
• Brand and certification: ask for BIS-certified bars from a reputed manufacturer, and a test certificate for larger lots.
• Weight: bars are usually sold by weight. Ask how weighment is done and get a weighbridge slip for large quantities.

Cement: types and freshness

• OPC (ordinary Portland cement) and PPC (Portland pozzolana cement) are the common types; use what your engineer specifies for each part of the work.
• Check the manufacturing date printed on the bags. Cement loses strength if stored too long — ask the supplier for recent stock.
• Bags should be intact, not torn or hardened.

Compare delivered prices

Freight changes the real price of heavy material.

1. Ask whether the quote is ex-godown or delivered to your site.
2. Ask whether unloading is included.
3. Check whether trucks can reach your site, and plan for narrow lanes.

Checking what arrives

• Count cement bags and check dates before signing the delivery note.
• Check steel for markings and diameter, and weigh a sample bundle if in doubt.
• Reject material that is rusted heavily, damaged or wet.

Storing material on site

• Keep cement off the ground on a raised platform, covered, away from moisture, and use older stock first.
• Keep steel off the ground and covered to limit rusting.

Mistakes to avoid

• Buying everything at once for a long job. Cement can lose strength while it waits; buy in stages.
• Accepting material without checking. Count bags, check dates and look at bar markings before signing the delivery note.
• Storing cement on bare ground. Moisture from the floor hardens bags from below; use a raised, covered platform.
• Changing the specified grade to save money. Always check with your engineer before accepting a different grade or type.
• Ignoring freight in comparisons. For heavy material, delivery can decide which quote is really cheaper.

What to include in your enquiry

• Steel quantity by diameter and the grade specified
• Cement quantity, type and preferred brands
• Site location and access for trucks
• Delivery schedule (all at once or in stages)
• Whether unloading is needed and whether you need GST invoices
