Life-cycle costs

A life-cycle cost calculation sets the construction costs against the operating costs over decades: cleaning, maintenance, energy, replacement of building components. Almost every one of these items is calculated via an area or a quantity. If the area is wrong, the calculation is wrong over the entire term.

When the need arises

  • Comparison of options before a refurbishment decision
  • Certification, when costs are assessed over the life cycle
  • Budget planning in facility management across several buildings
  • Tendering of operator services that are paid by area

Where the data comes from

This service calculates with geometry: areas, heights, openings, orientation, build-ups of building components. In a new building, the design model provides this information. In an existing building it does not exist, and that is exactly the usual stumbling block.

We collect this data during the as-built survey anyway. The same survey from which floor plans and the room book are produced also provides the values used in this calculation. No second appointment and no second data collection are needed.

  • As-built data capture – the survey this builds on
  • Scan-to-BIM – the as-built model, when you want to calculate rather than estimate
  • DIN 277 – the areas that go into almost every one of these calculations

The leverage lies in the areas

Cleaning is billed by floor area and type of floor covering, maintenance by component area, energy by heated area and envelope area. All these values are in the room book or result from the floor areas to DIN 277. Once you have collected them, you can keep calculating on the same basis for twenty years instead of estimating them anew in each cycle.

The link to operation is therefore not a side issue: the same data flows into the CAFM system.

These services build on the same survey. Anyone who needs one of them usually needs a second.
