Transcript Job Costs - Foremans Development Series

Objectives
In the 1st half of this Module we’re going to cover:
• The computerized estimating process.
• How a Contractor comes up with his Material
Costs and Labor Units.
The 2nd half of this module will look at how Labor
Units give us a way to check our Install Rates.
• Are we installing our materials in the time given
to us by the Job Estimate?
What’s the Point?
As we’ve seen in other Foreman Development modules, the Job Estimate
affects all other aspects of the Project:

Estimating Material Costs
• Big ticket items like Light Fixtures or
Switchgear are quoted as separate
packages in the Estimate.
• Getting quotes on Bulk buys will save $$$$
• Thousands of misc. electrical parts also
have to priced as part of the Estimate.

Estimating Labor
Labor Units
•
•
•
•
•
Labor Units are expressed in man-hours for the
installation of:
E = One or per each item
C = Per one hundred items
C = Per one hundred linear feet of the item
M = Per one thousand linear feet of the item
LF = Per linear foot
Labor Units vary by Jobsite conditions:
• Normal
• Difficult
• Very Difficult

What are your Labor Units?
• Your company had specific Labor Units
that they used when they bid your job
• Did your crew make the Estimate when
they installed that big rack of 4” EMT
conduits?
• If you are not making your install rates you
are in trouble!
Figure your Install Rate
A 2 person crew was told to install 2,000 feet of 4” EMT.
The NECA Labor Units for this material under normal
conditions is 16 Labor Units per 100’ of conduit.
1. How many feet of conduit should one person install in an hour?
6.25 feet per man hour
2. How long should this entire task take?
320 hours
3. How much conduit should be installed by your 2 man crew at the end of
5 days?
500 feet per hour
4. One day I had 4 people running conduit. How many feet of conduit
should they have put in?
200 feet
What’s Included?
What is and isn’t included in the Labor
Unit?
• Scope
• Work Operations NOT included
• Application Instructions
An Install Rate Example
• A 500’ long
conduit rack with
(4) 4” EMT
conduits.
• Supports every
8’= 63 racks
Calculators
Tracking Labor Estimates by Area
• Some contractors will break their Estimate
into small areas or phases
– So their take- offs will show the total labor and
materials quantities used in each of these
small areas.
• This method gives the Foreman in the field
a simpler way to track their labor in small,
quantifiable work areas.

Summary
Anyone want to be an Estimator?
• Well, maybe not, but at least we have a
better understanding of how they do their
work
• We need to be more competitive!
– In order to do that we need to be more
productive.
– System Productivity and checking our Labor
Install Rates are tools we can use to help us
do that.
