## Recursive Typicals
|
|
|
|
A competent quantity takeoff software must support **recursive typicals**.
|
|
|
|
> "Building Type A" has Levels
|
|
> * Level 01,
|
|
> * Level 02,
|
|
> * Level 03,
|
|
> * Level 04,
|
|
> * Level 05
|
|
>
|
|
> "Building Type A Levels 02-04" is typical of
|
|
> * "Building Type A/Level 02",
|
|
> * "Building Type A/Level 03",
|
|
> * "Building Type A/Level 04"
|
|
>
|
|
> "Building Type A" is typical of
|
|
> * "Building 1",
|
|
> * "Building 2",
|
|
> * "Building 3"
|
|
|
|
In all cases, a typical must behave as the **Type** it is typical of,
|
|
(i.e. the process to assign takeoff to "Levels 02-10"
|
|
must be essentially the same as to do so to "Level 01")
|
|
and the use of a typical must not exclude the use of the breakdowns it is typical of
|
|
(i.e. the use of "Levels 02-10" must not exclude the use of "Level 02").
