Two calculators, two different questions. Both share the same calculation engine (automatic estimation of commission hours, cost floor, MEF floor) and a year selector (2024–2027), documented in the technical methodology common to both.
For now, the available calculators are limited to architectural building projects. The plan is to extend the set of calculated scenarios to other kinds of commissions and other professions. Their purpose is not only to guide architects and the public authorities that set procurement prices, but also to show that it is possible to determine equivalent contracting values from sufficiently well-established data.
⚖️ Evaluator
Is the fee I was offered or awarded adequate?
Compares an amount already offered or awarded — in a public tender or a private commission — against the cost floor and the MEF floor, and flags whether it shows indicators of discriminatory undervaluation.
📊 Estimator
What fee should I propose for this commission?
Calculates in advance, from the PEM (construction budget), the building type and the scope of a project-drafting and/or site-supervision commission, a band of objective references — cost and value — before submitting an offer.
Neither tool is a tariff, a fee scale, or a recommended fee. Both compare specific figures against objective references, derived from regulatory and cost sources, not from professional-association criteria. The legal basis for this distinction is set out in the site’s Legal Framework.
Technical methodology
Every input the two calculators use (reference salary, operating costs, utilization rate, overheads, conversion rates…) has a different origin and status — regulatory, collectively-bargained, industry benchmark, or an editable working assumption. The full detail, with the step-by-step derivation of the floors and the automatic estimation of hours, is in the calculator’s technical methodology →.
