Cómo funciona, paso a paso

6 pasos a lo largo de la plataforma - qué hacer en cada uno y por qué importa.

1

Build the hourly cost of each function

Costes de mano de obra

Enter the wage each function is paid under the collective agreement of the region and the year, and keep the base wage and the encargos as two visible numbers rather than one loaded rate. Do it for the servente and the encarregado as well as for the pedreiro.

Por que: A loaded rate cannot be re-based when the agreement is renewed or when the payroll regime changes, and both happen inside the life of one estimate. Split, the same change is one figure edited in one place, and the composicoes underneath follow it.

Choose the payroll regime for the whole orcamento

Bases de la estimación

Decide whether this estimate is priced with the contribution on payroll or on turnover, check the edital in case it fixes the answer for you, and record the decision on the basis of estimate together with the encargos percentage it implies. One regime, one percentage, one orcamento.

Por que: Lei 12.546 of 2011 makes this a company decision with a real effect on the labour cost, and the reference bases publish a separate table for each answer. Recorded once at the top, it becomes a fact everybody working on the estimate can check against. Left implicit, it is rediscovered by whoever opens the file next, and they will assume whichever table they used last.

3

Rebuild every composicao on the chosen table

Partidas compuestas

Push the chosen encargos percentage through every composicao that carries labour, including the auxiliares underneath them, and read the change in the total. Do it as one pass rather than as a correction applied to the items somebody happens to open.

Por que: The auxiliares are what get missed, because they are priced early and then behave like insumos. An argamassa still carrying the other table quietly prices the mason inside it under a regime the rest of the estimate has abandoned, and the item above it looks entirely normal.

4

Prove nothing was left on the other table

Validación

Run the orcamento against the recorded regime and list every position whose labour still carries the percentage of the other one. Treat an empty list as the deliverable of this step, not as a formality.

Por que: This is the one error in the whole estimate that produces no symptom. A mixed orcamento totals cleanly, prints cleanly and reads as internally consistent, and it is discovered either by an analyst comparing your labour cost with the published table or by nobody at all. A machine asking the question line by line is the only reliable reader.

5

Compare the priced burden with the folha you paid

Nómina

Take a period that has closed and put the encargos you priced next to the encargos the payroll actually paid, split between the contributions, the paid absences and the provisions. Ask which part of the difference is a wrong percentage and which is a job that worked more overtime than it planned.

Por que: The published table describes an average company, and yours has a real absence rate, a real overtime pattern and a real turnover of labour. The gap is a fact about the company rather than about the job, and it is the same gap on every job until somebody measures it.

6

Feed the difference back into the next estimate

Postcálculo

Close the loop in post-calculation: put the difference beside the hours the site actually booked, decide which part is a permanent correction to your own encargos figure, and change the figure rather than remembering to add a bit next time.

Por que: A correction that lives in an estimator's head is applied on the jobs they price and nowhere else, and it leaves with them. A corrected rate in the cost database is applied by everybody, and the next comparison measures the correction instead of rediscovering the original gap.
