BRUCE LONEY, ASSISTANT CITY ENGINEER
CONSIDER APPROVAL OF CHANGE ORDER NO. 1
PROJECT 94-01, PRIOR SOUTH IMPROVEMENTS
DECEMBER 5, 1994
INTRODUCTION:
BACKGROUND:
During the course of construction for Project 94-01, additional work
beyond the Contract was done by the Contractor. A Change Order for
this additional work has been prepared and enclosed in the Agenda
packet for Council approval.
The contractor, Valley Paving Inc., and their subcontractors, have
performed additional work which was not included in the original contract.
The additional work is described and itemized costs are shown on the
enclosed Change Order form. A total of ten (10) additional items are
described with the total net cost of the Change Order being $11,441.55.
Previously a memorandum was given to Council in regards to the Change
Order work on September 20, 1994, which listed six (6) items at an
estimated cost of $5,360.00. Additional work was required to complete
the project beyond what was itemized in the September 20 memorandum.
Items #2 and 3 in the September 20, 1994 memorandum were also under
estimated due to unforeseen underground conditions.
Items #1 and 8 are associated with rework on existing storm sewer pipe
in which the pipe was either not needed or the pipe size changed to
match existing field conditions. Item #2 is associated with a repair of a
sanitary sewer service within the City's right of way. The existing sewer
service had a sag in the pipe and the service pipe was relaid and trench
bottom stabilized. The trench area had high ground water conditions,
thus considerable dewatering was necessary and the use of a trench box
to protect the workers. The high ground water made the repair more
difficult and more costly than previously estimated.
Items #3, 4, 5, 7 and 9 are extra work items associated with the City's
existing watermain system. Item #3 was for the repair of a defective
valve. Items #4 and 5 were in regards to locating the limits of a shallow
watermain and the actual lowering of the watermain under Brunswick
Avenue. The watermain was lowered to a minimum depth of four (4) feet
and insulated to prevent freezing. Items #7 and 9 are associated with
repairs to existing hydrants and repair of a water service.

Item #6 is associated with the landscape restoration at the corner of
Brunswick Avenue and Dublin Road which did not have a bid item
associated with the work. Item #10 is associated with the removal of an
additional tree located by the Blind Lake dredging work area and was
deemed necessary in order to complete the dredging work.
The total amount of this Change Order is $11,441.55 with the original
contract amount being $435,577.16. The addition of Change Order No. 1
represents a 2.6% increase in the original contract amount and the
contract amount total is now $447,018.71. Although the contract price
total will be $447,018.71, the estimated final contract total per MSA
Consulting Engineers will be approximately $431,000.00 including the
Change Order work.
The contractor has signed the Change Order and has performed the
work. Additional work was completed as recommended by the City's
consultant and City's engineering staff. This Change Order is for all the
extra work associated with this year's construction work on this project.
The alternatives are as follows:
Approve a motion authorizing Change Order No. 1 in the amount
of $11,441.55 to Valley Paving Inc.
Disapprove the motion for a specific reason.
Table this item for a specific reason.
The recommendation is to approve Change Order #1 as the contractor
has completed the work and City staff feels the additional cost is
acceptable.
This amount will be paid from the Construction Fund and will be included
with this month's construction voucher. Sufficient funds exist to pay for
the additional cost from this Change Order.
