1

Bring in SICRO for the state and the reference month

কস্ট ডেটাবেস

Load the SICRO tables for the state the road runs through and the reference month the edital names, and keep both on the record with the prices. Load the matching equipment and insumo tables rather than mixing a new servico table with equipment costs you already had.

কেন: SICRO prices differ by state because fuel, aggregate and labour do, and a road that crosses a boundary can legitimately need two tables. Fixing which table applies to which stretch now is a paragraph. Doing it after the proposals are open is a dispute in which both sides are quoting real published prices.

Build the hourly cost of every machine

যন্ত্রপাতি ও ফ্লিট

For each machine the method needs, set the ownership cost, the fuel and lubricant, the maintenance and the operator, and split the result into a productive hour and an idle hour. Do it for the plant that waits as well as the plant that works, the water truck and the roller included.

কেন: On a road contract the machines are the estimate. A single hourly cost averaged across productive and idle time prices a fleet that is always either working or parked, and no earthworks operation behaves that way. The two-rate split is what lets the composicao say honestly that the excavator drives the cycle and the trucks wait on it.

Turn the haul distances into measured transport

কোয়ান্টিটি টেকঅফ

Measure what moves and how far: cut to fill, borrow pit to embankment, quarry to plant, plant to laydown. Work out the distancia media de transporte for each pairing and carry it as a measured item rather than as a note beside a volume.

কেন: Transport is often the largest single cost on an earthworks job and it is the one most often taken from a drawing rather than from the ground. A DMT measured against real borrow pits and real access roads is a number both sides can check. A DMT assumed to be the straight-line distance is a claim waiting to happen the first week the trucks run.

Compose each servico around the machine that sets the pace

অ্যাসেম্বলি

Build each servico as an assembly whose production per hour comes from one machine, and let the rest of the fleet follow it as productive or idle hours. Keep the material, the labour and the transport as their own components so the cost of a cubic metre can be read apart from the cost of moving it.

কেন: A road composicao where every machine works at full production prices a fleet that never queues, and it is always the cheapest way to be wrong. Naming the machine that sets the pace makes the estimate say what the site will do, and it tells the planner which single piece of plant the programme depends on.

Price the orcamento and total it per lote

বিল অফ কোয়ান্টিটিজ

Apply the composicoes to the positions, carry the transport as its own set of items, and total the bill by lote and by segment so each stretch can be read on its own. Check that the earthworks balance in the bill matches the one the transport was measured from.

কেন: A road contract is usually awarded and measured by lote, so a total that only exists for the whole scheme has to be rebuilt by hand for every conversation. And an earthworks balance that disagrees with the transport measured against it means one of the two is describing a road that was not designed.

Record the SICRO reference and the haul assumptions

এস্টিমেটের ভিত্তি

Write down which SICRO table and month priced the work, which borrow pits and quarries the transport assumed, and which of those are not yet licensed or contracted. Name the assumptions that would move the price if they turn out differently.

কেন: The borrow pit is the assumption that changes most often and costs most when it does. Named in the basis of estimate before the bid, a pit that turns out to be unavailable is a variation with a documented starting point. Unnamed, it is a cost the contractor carries while explaining that everybody knew.

The market this case is written for

ব্রাজিল

Everything in this case follows how construction work is measured, priced and paid for in this market. The forms, the cost breakdown and the payment rules are the ones used there, not a generic version of them.

Standards it follows

  • Lei 14.133
  • SINAPI
  • ABNT NBR 12721

You do not have to set any of that up by hand. The first time you open the platform it asks which market you work in. Choose this one and it sets the interface language, loads the matching cost database and records the cost classification, and it adds an example project you can open straight away.

The rule checks for this market come with the platform too. Switch them on once and an estimate that misses something the market expects is flagged while you are still working on it, not after the tender has gone out.
