PROPOSED PAVLNG CUT
REPAIR COST
August, 1981
EXHIBIT A
CITY OF LUBBOCK
. MEMO
TO: Don Jennings
DATE:
FROM: _ Buzzy Yarbrough
su6JECT: Determination of Paving Cut Costs for 1981
The following criteria were used in the development of proposed paving cut
cost for 1981:
1. A minimum paving cut size of 50 square feet was established. This
minimum size was required to offset the cost of moving men and
equipment from another point to the cut to be repaired, plus the
labor and material involved in the actual repair.
2. A maximum paving cut size of 2,000 square feet was determined to be
the largest cut that could be repaired in a typical work day. A cut
larger than this would require more than one day to complete, therefore,
extra costs would be involved due to the additional movement of men
and equipment to and from the site.
3. A typical four man repair crew was used to establish hourly labor
costs. This cost was found to be $36.16 per hour which includes a
34% factor for overhead and benefits.
4. Three types of paving cuts were found to be typical of the repairs
made by the street department. These are:
A. Asphalt Only
B. Concrete Only
C. Asphalt and Concrete
5. Typical equipment requirements were determined for each type of repair
along with realistic "Actual Cost Hourly Rates" for each piece of
equipment.
6. Using the calculated cost for the minimum and maximum paving cuts as
known valves, graphs were prepared for each type to reflect estimated
costs for repairing any size cut up to 2,000 square feet. Repair costs
for any larger cuts than this should be calculated by the City Engineer.
7. From the graphs, charts were developed to indicate a single cost per
square foot for each increment of 100 square feet of paving cut size.
8. Paving cuts for brick streets should each be considered individually,
with an individual cost calculated by the City Engineer.

Determination of Paving Cut Costs for 1981
Attached are copies of the calculations, graphs and charts pertaining to the
development of the proposed costs.
You will note that minimum cost for the three types of patch have risen from
$2.65/square foot for asphalt only and concrete only patches in 1980 to
3.10/square foot for these patches in 1981. Also the minimum cost of the
asphalt and concrete combined patch has risen from $5.10/square foot in 1980
to $6.07/square foot in 1981. These costs are a direct result of the increase
cost of labor in item #3 above and the increase in rental equipment rates in
IB of the attached worksheets.

H. Considerations
1. It is realized that many variables, as indicated below will
affect the actual cost per square foot of a patch.
(a) Number of patches required per day.
(b) Area of each patch.
(c) Driving time to each patch.
(d) Driving time to hot mix plant.
(e) Number of men actually required by shape or condition
of patch.
(f) Operating time for each piece of equipment.
2. A typical daily situation must be assumed, as indicated by
Items F & G.
3. A "straight line" relation is assumed as the condition that
would exist between 5-50 S.F. patches and 1-2000 S.F. patch
on attached graph.
4. Limited records prevent an accurate analysis of type, size
and cost of individual patches.
I. Establish typical costs and number of 50 S.F. patches made in one day -
(For an Asphalt and Concrete patch.)
1. Assume an average of 5-50 S.F. patches can be filled with concrete
the first trip.to the patches.
2. Assume an average of 5-50 S.F. patches can be covered with hot mix
on the second trip which must be at least 3 days after the first
trip.
3. Expenses for first trip -
a. Personnel - (G-2) - $289.28
