Re: ESTIMATION PROGRAM

Gents:

i know this might be too simplistic, but here's how we do it...

1. in the conceptual estimating stage we simply use an estimate of $20 per inch per foot. in other words, for a 1" line, it costs $20 per foot to purchase materials and install. for a 2" line, it costs $40 per foot. we use this for carbon steel pipe in the sizes 1" thru 18".
2. in the refined estimating stage, we develop isometric drawings and perform a take-off. the take-off we send to the pipe supply house and let them add up the costs. we walk the job with our piping foreman and he provides the labor estimate.

hope this helps.
