�l�-RING �- -OSSOtI�T-�S October 25, 2012 File No. 170007E-0071 TRUI NO= Honorable Mayor and City Council City of Arden Hills 1245 Highway 96 W Arden Hills, MN 55112 RE: VALENTINE PARK IMPROVEMENTS PARTIAL PAY ESTIMATE #3 AND CHANGE ORDER#2 Dear Council Members: Please find attached 3 copies of Partial Pay Estimate No. 3 and Change Order No. 2 for the above-referenced project. As you are aware, the Contractor for the project is Interstate Pavement Maintenance. The total amount earned by the Contractor on this partial pay estimate is $205,952.32. Subtracting 5% retainage of $10,297.62 and previous payments in the amount of $177,036.96, the amount due the Contractor is $18,617.74. This pay estimate includes payment for rain water garden work, including the work covered by Change Order No. 2. We have inspected the work performed by Interstate Pavement Maintenance and find it to be in compliance with the plans, specifications, and contract documents. Also attached is Change Order No. 2. This change order is for modifications to the large rain water garden. After construction of the rain water garden, field monitoring determined that the filtration rate and corresponding draw down time of storm water captured by the garden was not as efficient as desired. Rock bedding around the drain the was added with filter fabric to increase the efficiency. This work has been completed and subsequent rain events have shown the garden to now be functioning as desired. We would recommend approval of Partial Pay Estimate No. 3 in the amount of $18,617.74 and approval of Change Order No. 2. If you have any questions regarding this issue please feel free to call.
