July 13, 2009 Item No. 7F Page 3 Estimated Project Cost Summary A summary of the estimated project cost for each Area is shown in the following table. These summary values were taken from the July 8, 2009 Update for Area B and the Feasibility Report for Area C. Further detail on these summary costs can be found in those two documents.

Savings on engineering costs 2. Lower construction costs 3. Savings on maintenance and other indirect project costs Based on the current professional services agreement between Bonestroo and the City, we estimate that approximately $18,000 cost savings in engineering fees will result from combining the projects. This savings is due to the economy of scale from preparing one set of construction documents for a single large project, rather than two sets of construction documents for separate smaller projects. A portion of the engineering cost for the project is also performed on an hourly basis, for items such as permit applications, coordination with agencies including Rice Creek Watershed District, Ramsey County, and MnDOT, as well as for construction surveying and inspection. Again due to economy of scale, if the hourly engineering work can be performed 5% more efficiently than it could be on two separate projects, the estimated savings on hourly engineering work would be on the order of an additional $20,000.
