Byg en samlet arbejdssats med den canadiske byrde

Del den timesats, du har brugt i årevis, op i grundlønnen og de navngivne bidrag ovenpå den, hold én skabelon pr. provins, fordi byrden er provinsiel, og registrer hvor hver sats kom fra, og den dato, den trådte i kraft.

Sådan fungerer det, trin for trin

5 trin gennem platformen - hvad du gør i hvert, og hvorfor det betyder noget.

1

Start from the base wage, one province at a time

Lønsatser

Create a rate template for the trade, enter the base hourly wage, and name the template for the province it belongs to, because the same trade carries a different burden in every province it works in.

Hvorfor: One template covering two provinces has to average something, and an averaged burden is precisely the thing you cannot explain when a bid gets queried. A template per province costs a few minutes to set up and is the only version that survives being asked where the number came from.

2

Add each contribution as its own named line

Lønsatser

Build the stack on the wage as separate lines: pension contribution, employment insurance at the employer multiple, vacation pay, statutory holiday pay, workers compensation at the classification unit rate for this trade, and the benefit contributions that apply. Keep percentages as percentages and fixed amounts as amounts rather than blending them into one uplift.

Hvorfor: A single burden percentage hides the fact that its parts move independently and on different dates. Workers compensation in particular is rated by classification unit, so it changes when the work the crew does changes, not when the calendar turns, and that is the movement a blended uplift will never show you.

3

Write down where each rate came from and when it applied

Overslagsgrundlag

Record in the basis of estimate the source of every contribution in the stack, the body that administers it, and the date that rate took effect, so the whole stack can be re-checked against its authorities in an afternoon.

Hvorfor: When the rate moves you will be asked which line moved, and the answer has to be a citation rather than a memory. It is also what turns a rate into something a colleague can maintain after you, which is the whole difference between a company rate and a personal one.

4

Point the assemblies at the rate, not at a typed number

Sammensatte poster

Build the crew compositions and assemblies against the rate template rather than against a figure typed into each one, so that a change to any contribution reprices everything that depends on it.

Hvorfor: A rate typed into forty assemblies is forty rates, and they will not all be updated on the day a premium changes. Pointing at the template is what makes the next update a single edit instead of a search that finds most of them.

5

Test the built rate against what the job actually cost

Rapporter

Report the built rate against recorded hours and paid cost on a job that has finished, component by component, and correct the line that is wrong rather than adjusting the total until it matches.

Hvorfor: A stack is only worth building if it gets corrected, and correcting a total teaches nobody anything. Fifteen years of experience tells you what the number should be; the stack tells you which part of it drifted, and only one of those two can be handed to the next estimator.

The market this case is written for

Canada

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

  • CCDC
  • CSA
  • NBC 2020

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.
