Assemblies
In construction-estimating-software, assemblies are groups of material items representing a specific scope of work.
Assemblies reduce the effort required for takeoff by grouping related items, for example 3/4" EMT connectors and couplings in addition to conduit.
Assemblies allow... (in order of necessity):
- complex items (devices, conduit runs, etc.) with known proportions to be counted as one.
- changes to be made to measures and counts without recounting an entire area.
- takeoffs to be skimmed for obvious deficiencies that would otherwise be obscured
- changes to be made to project requirements (specifications) without recounting an entire area.
If we agree on the definition of Branch Wiring: 2#12 #12G; 3/4"C, EMT; On Structure
and its contents as ratios of its length,
then their quantities can be calculated with only one measurement.
This is how "estimating software" assembly takeoff works, however its a simple generic process, possible with several tools an estimator should be familiar with:
