| Several assumptions are made in
order to compare costs. Savings are based on the average
man-hours it takes to install a 6x40 quadrapole loop using a
3/8" saw cut. Using a pump and want system, average
man-hours per loop. Using R. Hart's system and TA-500, average
man-hours are 3.5 man-hours per loop. For ease of
understanding in our example, we are assuming an average labor rate
of $10.00 per hour, plus an approximate labor burden of 22.5%.
This will give you an average labor rate of $12.25/hour.
You will have to make adjustments suing your
own average labor rate to determine your savings by using TA-500 and
the R. Hart's system. Depending upon the size of loops that
you use and the saw cut of your loops; your saving may vary.
This example demonstrates simple averages for the use of TA-500.
The following table illustrates total savings
using TA-500 and the R. Hart system:
