Explanation
BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the construction contract with Kokosing Construction Co., Inc. for the Dublin Road Water Plant (DRWP) Raw Water Intake Improvements Project, for the Division of Power and Water. As with any construction project being performed, it is possible unanticipated conditions may arise which would require a construction contract modification. At this time, the complete estimated cost breakdown is as follows:
· $110,000.00 - Installation of a guard house, additional pavement lane and associated appurtenances to enhance security at Utilities Complex entrance.
· $125,000.00 - Full scale rebuilding of the south abutment including sheet pile installation.
· $80,000.00 - Additional grouting to stabilize the existing low-head dam due to unknown voids encountered.
· $31,500.00 - 10% Contingency
The total amount of this modification is $346,500.00, a 6.06% increase to the original contract cost.
1. Amount of additional funds to be expended: $346,500.00
Original Contract Amount: $5,715,600.00
Amount of original contract and this modification: $6,062,100.00
2. Reasons additional goods/services could not be foreseen:
· The guard house was designed and installed as an increased security measure at the Utilities Complex.
· The south abutment had deteriorated beyond the original estimated scope of repairs due to the unseasonably wet June '08. The high flows and the force of the river significantly damaged the south abutment.
· The low-head dam repair quantities were originally estimated by the design engineer. The dam was originally constructed in the late 1800's (and significantly rehabbed in 1919 and again in 1936 and in 1950) and was in need of rehabilitation. The true extent of the repairs could not be determined until the dam area was dewatered and fully investigated. The extent of these repairs exceeded the original estimates.
3. Reason other procurement processes are not used:
This modification keeps the contractor on the project and on schedule to finalize the Dublin Road Water Plant intake and low-head dam improvements. It was not determined that the additional work at the low-head dam was needed until the contractor built temporary cofferdams and dewatered the dam. At that point it was necessary to make the needed improvements as soon as possible in order to restore the stream flow to the normal conditions. It was not practical at that time to bid the work out to another contractor, in addition the additional cost and time associated with bidding out this work would well exceed any benefit.
4. How cost of modification was determined:
Costs were submitted by the Contractor and reviewed and verified by the construction administrator and engineering consulting team.

Emergency Designation: Emergency legislation is being requested to provide these services concurrently with the ongoing construction contract and to finish the work while the contractor has the river flows partially diverted by use of a cofferdam. In addition, it is in the City's best interest to complete the work within the river during the traditionally low river flow months of September and October prior to the higher river flows traditionally experienced in winter months.
FISCAL IMPACT: This legislation includes a transfer of funds within the Water Works Enlargement Voted Bonds Fund and an amendment to the 2008 Capital Improvements Budget.
