SUBJECT:
Resolution authorizing the Director of Purchasing to execute the Contract Change Order Request Number 1 with Performance Construction & Engineering, LLC, 217 W. John Street, Plano, IL 60545 for the 77 S. Broadway Ave. Parking Structure & 65 Water St. Demolition Project.
PURPOSE:
To increase the Contract by $30,000.00 from the original value of $578,000.00 to a new Contract value of $608,000.00.
BACKGROUND:
This change order is necessary to increase the contract value to address two unforeseen work items encountered during construction, as discussed herein.
Per the bid documents, the existing brick walls on the north and south side of the parking structure were to remain in place with new brick installed in the locations where the parking deck was attached. After removal of the parking deck, it was determined that the outer layer of brick on each wall was not structurally sound and complete removal would be required. The remaining underlying walls were a mixture of limestone, various types of brick and sections of poured concrete with varied finishes. Not only were the walls in poor condition aesthetically, but also structurally, as extensive repairs to the mortar joints would be required. After analyzing various options to address the walls, the application of a spray on concrete product known as shotcrete was selected. Shotcrete was the most cost effective option to address the deteriorated joints, and the product also addressed the aesthetic issue by providing a uniform finish to the varying materials of the existing walls. The cost of the shotcrete was approximately $78,000 which was offset by other contract savings of approximately $81,000. Included in that savings was the cost for the originally planned brick wall repair and approximately $10,000 of new sidewalk that will now be installed at a later date when the site is completely backfilled.
The other substantial increase to the contract cost was a result of the placement of 33 additional cubic yards of structural concrete. After the parking deck was removed, a structural engineer conducted a follow up analysis of the building and recommended that additional structural concrete be poured around the building columns. This additional concrete would sufficiently replace the lateral support previously provided by the parking deck. The cost for the additional concrete was $33,000, which requires a contract increase of $30,000 that is approximately 5% of the original contract amount of $578,000.
DISCUSSION:
This additional work will be completed using account number 353-4010-417-71-01 which has a 2018 budget amount of $3,400,000.00.
IMPACT STATEMENT:
Executing this change order request to increase the Contract value will allow for payment for work that was required due to unforeseen issues that arose during construction that were not previously accounted for in the contract pay items.
RECOMMENDATIONS:
I request this resolution be adopted.
