01 · PRINCIPLES

What “research-informed” means

CalcPura does not claim that one universal cleaning speed applies to every property. The model separates externally published benchmark data from configurable assumptions and tenant observations.

01

Room type matters

Offices, sanitary areas, kitchenettes, corridors, stairs, treatment rooms and glass surfaces have different productivity characteristics.

02

Furnishing matters

Room equipment, occupied surfaces and obstacles affect effective productivity. CalcPura therefore models furnishing and kitchen complexity separately instead of treating every square metre equally.

03

Scope must not be double-counted

If a benchmark already includes a task bundle, the same task should not be added again as a separate unit allowance.

04

Measurements improve defaults

Repeated object-specific time measurements are used to compare estimates with actual work and refine coefficients.

02 · DATA STATUS

Every number should say where it came from

INDUSTRY_BENCHMARK

A numeric range or method published by an external industry source.

FRANKIFLOW_ASSUMPTION

A practical starting value used for the v1/v3 model until enough representative job data exists.

FRANKIFLOW_OBSERVED

A value measured from completed jobs using a consistent scope and timing method.

HYBRID_CALIBRATED

A benchmark that has been adjusted using a sufficiently representative operational sample.

03 · PRIMARY SOURCES

Published material used in the model

The linked documents are source material for methodology and starting benchmarks. They do not endorse CalcPura and do not prescribe every CalcPura coefficient.

04 · CALIBRATION LOOP

A calculator that can learn from operations without hiding its assumptions.

  1. 1Start from a suitable benchmark or documented assumption.
  2. 2Estimate workload and quote using the tenant’s own costs and margin.
  3. 3Record actual cleaning time and relevant property conditions.
  4. 4Compare estimate vs actual and update coefficients only with representative evidence.
