Kostenschätzung with the office's cost benchmarks

The project overview works out a Kostenschätzung to DIN 276, first level, as LPH 2 asks for it: every cost group from KG 100 to KG 800 with its amount and how it was found, and the total against the budget agreed with the client. It follows the models as they are now.

The office's cost benchmarks

  1. Under Library, tab Cost benchmarks, the office keeps its own values: € per m² BGF or m³ BRI of KG 300 and 400, by building type, each with its year, region and source. None are supplied: cost data books such as BKI are licensed.
  2. Type them, or Import from a spreadsheet…: open a CSV file or paste rows from Excel, say once which column holds what, and what no column holds is the same for every row. Building types are matched by name; new ones are added.
  3. Building types start from the usual German list; rename, hide or add your own. A type renamed keeps its values and projects.
  4. Save the draft, then publish it as a new version. A published version never changes.

A project's version

  1. A new project uses the latest version. It stays on it when the office publishes another.
  2. In the project settings, under Cost benchmarks, the project lead sees what another version changes, and a warning, before changing to it. Older versions can be chosen too, with a stronger warning.

The estimate

  1. On the overview, under Kostenschätzung (DIN 276), choose each building's type; KG 300 and 400 are then its BGF or BRI times the benchmark, times the price index you enter.
  2. KG 100 is a sum, or the land value times the plot: a Bodenrichtwert taken over from BORIS is offered.
  3. KG 200 and 500 to 800 are a sum or a share of KG 300+400, or left out.
  4. The project lead enters the budget; the overview says how far over or within it the estimate is.
  5. Save the estimate. A line that can't be worked out says why, and nothing is guessed.

In a release and a decision

  1. When a stage is closed, the release keeps the estimate as signed, with the budget and benchmark version of that day.
  2. A decision's variant offers Work out its costs: the estimate with the variant's buildings, against the main branch.
