MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: David C. Patek, Director of Public Works
DATE: September 24, 2010
RE: Change Order No. 1 for Public Works Contract No. 10 -08 /Integrity Grading & Excavating, Inc.
/Knapp Street Quarries Landfill Gas Venting System ( +$74,250.96)
BACKGROUND
Change Order No. 1 for Contract No. 10 -08 is scheduled for consideration by the Common Council at the
September 28, 2010, meeting. The contract was originally awarded to Integrity Grading & Excavating of
Schofield, WI, in February of 2010.
ANALYSIS
This change order adjusts the estimated bid quantities to the actual quantities installed during the
construction. This change order also addresses the adjustments required per the actual conditions found
at the site. For example, the location for the edges of the existing quarry did not match the locations
shown on historical documents. This change required the contractor to spend additional time to complete
test pits ( +$5,250). Another changed condition related to the amount of soil that covered the former
quarry areas. This greater cap thickness required the contractor to expend additional effort to stockpile
dirt in the park ( +11,875.50) and additional effort to restore larger areas of the park property ( +9,595).
Additionally, the garbage that was removed from the site was found to be mixed with a large amount of
dirt. This soil increased the weight of the material that was hauled to the Winnebago County Landfill
( +11,032). Finally, delay with obtaining permission for access to adjoining properties required the
contractor to remobilize a crew to complete the final vent pipe installation at Knapp Street ( +$6000).
FISCAL IMPACT
The construction funding ($1.0M) for the project is included in the Property Improvements Section of the
2010 Capital Improvement Program. The original bid award of $574,000.39 will be increased to
$648,251.35. The landfill tipping fees (approximately $260,000) have been paid directly to Winnebago
County.
RECOMMENDATIONS
recommend approval of the Change Order # 1 to Contact No. 10 -08 in the amount of $74,250.96 to
Integrity Grading & Excavating, Inc.
Respectfully Submitted,
