APPROVAL OF CAPITAL PROJECT AMENDMENT FOR BRADLEY CREEK SEWER JUNCTION
BOX REPLACEMENT AND ADOPTION OF BUDGET ORDINANCE AMENDMENT 2008-80
Interim County Engineer Dennis Ihnat reported that the Bradley Creek sewer junction box replacement
capital project ordinance was approved by the District on August 13, 2007 with the contractor, T.A. Loving,
beginning the work on the site in mid-September. During the course of the work, it was discovered that the original
24 inch effluent line that connects the junction manhole to the pump station is defective and needs to be replaced.
This line replacement was not in the original scope of work per Change Order #4. Additionally, a new interconnect
for the Northeast Interceptor flow management, new force main sample taps, and a new connection for the odor
control vent pipe to the junction box are required as a result of the reconfiguration of the incoming force mains to
the junction box.
At the District's request, T.A. Loving has submitted estimated cost for these items. The cost to install the
new effluent line and other needed upgrades is $239,500. This figure also includes the cost of the revised bypass
pumping that is needed to complete the additional work.

This additional work is critical to ensuring a quality project with regards to upgrading the County's lines
and manholes at the pump station, returning the station to a normal operating mode so the City can complete all the
required pump station upgrades required by the Special Order of Consent and ensuring safe and effective operation
of this critical infrastructure link in the Northeast Interceptor system. Timely completion of this project will assist
the City in completing the required work so the Northeast Interceptor moratorium and Special Order of Consent can
be removed.
Staff is requesting the District Board approve the capital project amendment for the Bradley Creek Sewer
Junction and adopt the Budget Ordinance Amendment 2008-80 in the amount of $239,500.
District Chairman Kopp requested direction from the Board.
Motion:
District Commissioner Greer MOVED, SECONDED by District Vice-Chairman Caster, to approve the
capital project amendment for the Bradley Creek Sewer Junction and adopt the Budget Ordinance Amendment
2008-80 in the amount of $239,500.
A copy of the budget ordinance amendment is hereby incorporated as part of the minutes and is contained
