Jim -
Per a phone conversation with John earlier this week, I am providing an explanation for the cost overrun on the
above mentioned project.
The following is a detailed explanation regarding the Contract overrun for Bid #7366 "Harmony Road Maintenance
Project" as awarded to Martin Marietta Materials in the amount of $2,047,316.21.
Change Orders #1 through #8 were additional work items added to the original Contract. These Change Orders are
approved to date and are listed as follows:
• CO #1 through #4 $ 80,488.40 Paid with Pay App #1 and #2
• CO #5 through #8 $ 24,606.22 To be paid with Pay App #3
TOTAL $105,094.62
The Total Adjusted Contract Amount was revised to $2,152,410.83. The Change Order percentage for the above
items equals 5.1% of the original contract.
Change Order #9 was a net zero, administrative Change Order to change $22,274.35 from the Harmony
Maintenance Fund to the Street Maintenance Program.
Change Order #10 is for the reconciliation of quantity under run and overrun based upon the line item pricing per
the original Contract.
Item #403-01 "Hot Mix Asphalt Grade S"
• The City estimated 13,030 Tons of material at a bid price of $61.45 per Ton.
• The post -construction analysis between the City, the design consultant and the Contractor shows that the
area on Lemay, north of Harmony, was not included in the bid tab which added 300 Tons
• The College to JFK stretch of road was profile milled from curb to curb in both directions because the
existing cross slope was flatter than 2%. We placed an average of 2.5" of asphalt back in this stretch, as
opposed to the design of 2", which added 400 Tons.
• The JFK to Boardwalk stretch of road also had a substandard cross slope. We placed an average of 2.5" of
asphalt back in this stretch, as opposed to the design of 2", which added 500 Tons.
• The intersections of Harmony Road with Boardwalk and Lemay were constructed with an average of 3" of
asphalt to amend existing drainage issues and ride quality issues. This added 400 Tons.
• We placed 2.5" of asphalt back from Lemay to McMurry to address various pavement deficiencies; as
opposed to a 4" mill and inlay which we used for correction between College and Lemay. This added 900
Tons.
• The northern and southern tie-ins at McMurry were extended to rehabilitate areas in need of repair. This
added 300 Tons.
• The estimated weight of the material (specific gravity) prior to bidding was figured as 108 pounds per
square yard. The actual weight of the placed material was 112 pounds per square yard. This added 670
Tons to the total
• In total, we added 2,800 Tons to the Contract and an additional 670 Tons due to the weight of the
material. The final Asphalt Grade S quantity was 16, 470 Tons. At $61.45 per Ton, the cost overrun was
$211,516.43.
Item #403-02 "Hot Mix Asphalt Grade SG"
• The City estimated 7,000 Tons and the final amount totaled 5,828 Tons. At $56.90 per Ton, the cost under
run was ($66,685.09).
• The under run for this quantity was offset by additional, City approved "Hand Patching" areas (see below)
Item #403-03 "Hot Mix Asphalt Hand Patching'
• The City estimated 500 Tons and the final amount totaled 1,618 Tons. At $79.15 per Ton, the cost overrun
was $88,458.04.
• The additional Tons were approved by the City and deemed necessary to mitigate areas where we had a
soft pavement edge and / or deeply cracked areas through the pavement section
• The pavement material placed with "Hand Patching" was the Grade SG mix
• When combined with Item #403-02 from above, the net difference is $88,458.04 - $66,685.09 = $21,772.95
of overrun
Item #630-03 "Flagging'
• . The City estimated 1,200 Hours and the final amount totaled 3,418.5 Hours. At $21.65 per Hour, the cost
overrun was $48,030.53
• The additional Hours were approved by the City and deemed necessary for the safety of the travelling
public, the safety of the workers and to allow material delivery
• The City under estimated the number of hours to be used, especially on top mat paving days where the
Contractor used tandem pavers
When added these four items together the net change order is:
ra
Item #403-01 "Hot Mix Asphalt Grade S"
Item #403-02 "Hot Mix Asphalt Grade SG"
Item #403-03 "Hot Mix Asphalt Hand Patching"
Item #630-03 "Flagging"
TOTAL:
$211,516.43
($66,685.09)
$ 88,458.04
$ 48,030.53
$ 281,319.91 (13.7% of the original Contract)
All other pay items in the Contract, other than the four listed above, reconcile to a net ($309.48)
When the overrun / under run items are combined with the additional work items approved in Change Orders #1
through #8, the project grand total is:

Intersection Funds.
