MEMORANDUM

To: Jeff Weyandt,Asst City Engineer,City of Shakopee
From: John Swanson
Subject: CSAH 83 Culvert Improvements
City Project No.2015-3
Extension Agreement For Inclusion of Field Entrance and Associated Culverts
Mr.Weyandt:
Bolton&Menk has incurred additional costs during data acquisition,plan preparation,and construction
of the above referenced project as a result of the addition of the design and construction of a field
entrance/driveway and associated culverts across the existing ditch for the Weckman property. The
subject ditch crossing is located approximately 1200 feet west of CSAH 83.
The Extension Agreement fee estimate submitted on 1/8/15,included work associated with installation of
a culvert(s) below CSAH 83,per the City's request. The subject field entrance/driveway and associated
culverts design and construction were not included in the original project scope,and were added to the
project at the City's request. Subsequently,throughout the project development and design process,the
inclusion of the field entrance and culverts was added,deleted,and then ultimately added back in to the
project for bid and construction.
The original Extension Agreement fee estimate total amount was$41,382.00.
It is our understanding that the project is now complete, and asbuilt plans have been submitted to the City
in accordance with City requirements.
Bolton and Menk's costs incurred through 11/6/15 are$54,495.50.Thus we have incurred extra costs of
$13,113.50($54,495.50-$41,382). All of these additional costs are attributed to the addition of the field
entrance and associated culverts to the project,design,agency coordination,coordination with the City,
plan preparation,bidding,construction and asbuilts. We have reviewed our project billing records and
have accrued the following staff hours and associated costs associated with the field entrance and
associated culverts addition:
Staff Hours Rate Cost
Senior Engineer 28 145 $4060
Design Engineer 35 102 $3570
Senior Technician 41.5 110 $4565

The above cost summary shows that the Bolton&Menk design team spent about 1 week of time to
coordinate, preliminarily design,remove, add back in,complete final design and restoration plans,
specifications,and asbuilt drawings for the field entrance and associated culverts for this project.
Considering the above,we respectfully request an Extension Agreement addition of$13,100.00 to the
above referenced project as follows:
Costs Incurred through 11/6/15 (Final): $54,495.50
Original Fee Estimate: $41,382.00
