Project LaPorte Road Pumping Station and Force Main
Owner's Contract No.
847 Contractor: Ricklefs Excavating
Date of Contact Start January 28, 2014
Contract Amount: $ 352,134.00
You are directed to make the following changes in the Contract Documents. Description:
1-1 Additional Jib Crane Base at Wet Well $ 466.26
1-2 Modifications to Air Release Manholes $ 11,057.00
1-3 Temporary Access at Marigold Drive $ 10,223.10
1-4 Additional Cost for Marigold Drive Asphalt Patch 105 SY @ $42.70/SY $ 4,483.50
TOTAL ADDITIONS $ 26,229.86
Reason for Change Order
1.1 Due to the orientation and size of the wet well, the portable jib crane cannot reach the pumps, the trash basket, and the
trash basket pad from one location. As a result, a second jib crane base will be installed to allow the portable crane to be
operated from either base location and reach all points.
1-2 Two (2) standard air release manholes with rock floors were installed for this project. These manholes have been
installed and are now filling with water from the surrounding soil. As a result, these manholes need to be removed and
have new bottom sections with concrete floors and sealed pipe connections installed.
1-3 The sanitary sewer crossing of Marigold Drive cannot be completed while leaving Marigold open to one-way traffic. As a
result the street will have to be closed. The surrounding streets are private drives and cannot be used for a temporary
detour. In order to maintain access to the businesses at this location a temporary gravel drive will be installed north of
the existing street. The gravel utilized for this temporary drive shall be the same material that is required to be Installed
around the pump station site. Once Marigold Drive is available for use, any rock that is salvageable will be removed and
placed at the pump station site at no additional cost and will offset a portion of the cost of the rock surfacing bid Item
1-4 The plans call for a concrete patch to be placed in Marigold Drive due to the cold weather schedule of the contract. Since
the work at this location is being done in the spring the City would like an asphalt patch to be Installed that matches the
existing roadway pavement. This item will be paid as an extra charge In addition to the concrete patching Item already
Included in the plan set.
