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.
