Computer Estimating
Computer Estimating
I concur with John and would like to expand a bit.
One of my adventures in the early 1980's was to help develop and market a computerized electrical estimating system. At $50k to $100k per system at that time it was not successful.
I returned to estimating and managing for varying size firms and projects, eventually settling in to a routine of taking on troubled projects and companies.
One of the common fundamental elements I found in most of these failures was management's failure to critically evaluate the estimates of their employees. I'm certain that the industry is more sophisticated now, but I have been skeptical about the use of computerized estimating since then.
The computer, in my experience, helps apply prices and labor units, but does nothing to enhance the material survey, and understanding of contract documents and project environment that must underly any estimate.
In situations where I did similar types of projects I built my own spreadsheets to define assemblies and basic work and found myself more consistent and profitable.
If one is using a computerized estimating system it certainly would be of value to learn what makes that system tick. And most modern estimating systems give some structure to the overall cost of a project.
However, In my opinion it is much more valuable to develop ones own consistent discipline in analyzing and quantifying the needs and costs of projects one is likely to estimate and/or manage.
