What’s your number?

Set your fees, your team and your rates. Watch the invoice your practice already pays — quietly, every project — add itself up.

YOUR PROJECT

Design fee (fixed)

The agreed fee for one complex project.

Project length

Design phase, start to handover.

Average team size

People working on the project, averaged over its life.

Staff cost

What one staff hour costs you, fully loaded (not salary).

Lead / senior cost

Per hour, fully loaded.

Planned margin

The profit you plan on this fee.

Places where project information lives

Count them: server, e-mail, Teams/chat, Dalux/CDE, Revit/ACC, phone photos, paper… The more scattered, the more hunting and asking.

Correction rounds at authority review, typically

How many resubmission rounds your last permit went through. US city data: 2–3 cycles are typical for commercial work.

Hours searching documents, per person / week

Measured: ~7 h for knowledge workers (McKinsey), 5.5 h in construction (FMI). We default lower.

Complex projects per year

Projects of this scale your practice runs annually.

YOUR INVISIBLE INVOICE · PER PROJECT

—

That is of your planned margin on this project.

The hunt
searching for answers that already exist
—
The echo
seniors re-answering what documents should — scaled by how scattered your information is
—
The drift
rework on stale information, 5–9% of hours × the 48% data-driven share — research reports more
—
The late catch
from your correction rounds: 200–450 h redesign per round + resubmission admin
—

HOURS, NOT NEW SPENDING

—

project hours your team already works, priced at your own rates

RECOVERABLE WITH ARCHIE

Model (all lines are ranges): hunt = your search hours × team × weeks × staff rate, ±25%, scaled by information scatter (5 places = neutral) · echo = your leads × 2–4 h/week × lead rate, same scaling · drift = 5–9% of project hours as rework × the 48% data-driven share, at staff rate · late catch = your correction rounds × 200–450 h redesign at a blended rate + admin, capped at 6% of fee. Recovery rates (same as the deck): 50% of search time, 40% of interruptions, 40% of data-driven rework, 70% of late findings — the interruptions line is our assumption; no industry statistic exists. Sources: McKinsey Global Institute (2012): knowledge workers spend 19% of the week (~90 min/day) searching and gathering information · FMI/PlanGrid, “Construction Disconnected” (2018, 599 construction leaders — contractor-side): 5.5 h/person/week searching; 48% of US rework from poor data · FMI/Autodesk (2021, 3,900+ professionals): bad data caused ~$88bn of global rework in 2020 · Love (2002) & Burati et al. (1992): total rework ≈12% of contract value, design-induced share largest · Get It Right Initiative (2016): avoidable error 10–25% of project value · US city plan-review records: 2–3 correction cycles typical. The studies date 2012–2022 — every euro figure here is time × the rates you set above.
