RE: Beltline Road E/W
Revised Cost Estimate
Dear Mr. Griffin:
A cursory review of the cost estimate prepared in April, 1989 for the Beltline
Road E/W Project has been made. The cost estimate was compared to recent bid
tabulations for similar projects. These included:
1. Royal Lane dated January, 1992;
2. Parker Road in Plano dated January, 1993; and
3. Josey Lane dated May, 1993.
The unit prices varied considerably from project to project. After reviewing
all of the bid tabulations, it could be generally concluded that concrete prices in
1989 were on the order of $13 - $14 per sq. yard. Today's prices for concrete paving
appear to be on the order of $20 - $21 per sq. yard. This would increase the overall
cost of the Beltline Road project approximately 15%. Storm sewer prices appear to
be up about 10% from the 1989 prices. This would increase the overall cost
approximately 21/2%. On a cost per mile basis, the construction costs are currently
running $2.5 - $2.7 million per mile. Therefore, in today's market, the original cost
estimate prepared in 1989 is probably within 5 - 10% of what it would cost to build
the project today.
For planning purposes the estimate should be increased 10-15% because it
will be 1994 before it can be bid.

T.U. Electric has informed us that it will probably be 1-2 weeks before they
can revise their estimate of what it will cost to relocate the power transmission lines.
As soon as we receive that updated information, we will forward it to you.
If you have any questions regarding this matter, please contact our office.
Yours truly,
