Re: Change Order No.2 ',
2015 Pavement Management Project :�
Dear Ms. Levitt, ;
Transmitted with this letter are three copies of Change Order No. 2 for the 2015 Pavement Management
Project.
This change order includes work to construct concrete driveway aprons for the AGCO expansion, repair i
additional water valves with corroded bolts, additional Grey Cloud Trail storm sewer work, and perform
subgrade correction in the Woodridge neighborhood. Below is an explanation of the items, and figures have
been attached that depict each item.
AGCO Expansion: '
When AGCO submitted expansion plans,the concrete aprons within City right-of-way were added to the City �
contract. The City's developer-friendly approach of coordinating improvements helps facilitate growth within !
the business park. The work was incorporated into the City contract so that the aprons were constructed
with the new street. Coordinating and timing this work avoided cutting into and patching a newly
constructed street, and took advantage of favorable costs within the larger City contract.
Valve Repair:
As part of the original contract,select valves within the project were identified to be dug up,evaluated for �
condition,and the corroded bolts were replaced prior to constructing the new street. Where severely
corroded bolts were encountered, adjacent valves were checked and replaced accordingly. A total of ',
eighteen additional valves were replaced as a part of this process in order to avoid more costly repairs in the '
future.
(
Grey Cloud Storm Sewer: �
While installing a segment of storm sewer,shallow bedrock was encountered in an isolated area. This �
required extra time and equipment to remove the rock and install the storm pipe and two structures. �I
Woodrid�e Nei�hborhood Sub�rade: j
Once the pavement was removed on 83�d Street,Jergen Avenue,and Jensen Avenue,the remaining grave)
base showed signs of movement and poor subgrade soils. In order to correct these areas,isolated areas of i
poor material were excavated, removed,and replaced with suitable materials.

Assessment Impact: I
Due to the low bid received on this project,this change order is not expected to impact the proposed '
assessment amounts that were contained in the feasibility study and presented at the public hearing. The I
bid received came in approximately$1 million under the original estimate. In addition, items for work
outside of the neighborhood areas, like the AGCO aprons,are removed from the assessment calculation.
It is therefore recommended that the City of Cottage Grove approve this change order.
If you have any questions regarding this change order, please feel free to contact me at 651-968-7674. '
