# Estimating Dimensionality
|
|
|
|
## Flaws of Traditional Estimating Methods: Enforced Linearity
|
|
|
|
Something that I've realized that really bothers me
|
|
about the the traditional methods
|
|
(e.g. database-based takeoff, audit-trail-type-abstraction)
|
|
is the the _enforced linearity_,
|
|
which is at odds with the reality of takeoff.
|
|
|
|
No matter how you slice it,
|
|
the user is thinking about your takeoff in some linear fashion.
|
|
Whether it's the takeoff creation date, or however they've sorted it,
|
|
Really date is the only useful measure,
|
|
but it's also useless, because you forget stuff.
|
|
|
|
The fact that forgetting something
|
|
totally disrupts a previously logical timeline of takeoffs
|
|
means that you stress about every single takeoff;
|
|
Instead of being in a flow state,
|
|
you have to be thinking 10 steps ahead.
|
|
|
|
I mean, I do, because I care about that sort of thing.
|
|
I suppose other people may not be as concerned,
|
|
but that doesn't really justify it.
|
|
|
|
The problem is that there's nothing linear about electrical installations,
|
|
at best it's a directed acyclic graph.
|
|
You can almost represent that linearly
|
|
if you go down each branch to the end
|
|
and then pick a new new line,
|
|
but that's unideal.
|
|
|
|
## Spatial Indexing
|
|
|
|
Scope exists in a three-dimensional space,
|
|
more if you suppose phases and bid options
|
|
as having a position on time and decision space axes respectively.
|
|
|
|
The most idiomatic alternative to time-indexed takeoffs
|
|
would be to represent them in the space of the drawings,
|
|
then only extend them as necessary.
