In DFE-Capital/blockbuster: Deterioration model of the School Estate

Description

An internal function in blockbuster to select the correct repair cost constant for a building component and its condition grade. It works by matching on the concatenated elementid and grade.

Usage

blockcoster_lookup(the_elementid, the_grade,
  costs_lookup = blockbuster_pds_repair_costs)

Arguments

the_elementid	the building component unique identifier found in the PDS.
the_grade	the grade of a blockbuster tibble single row (a factor with 6 levels).
costs_lookup	the relevant costs look up table, default is derived from PDS 2016 costs

Details

The default is to use the repair cost estimates for the PDS plus an E grade cost estimator based on D grade cost plus 5 is likely to be a source of error as the replacement of a decommisioned component depends on the component as well as other complexities. This should be addressed in later improvements of the blockbuster.

Value

a numeric constant for the repair cost of building component by grade, in pounds per unit_area.
