ANALYSIS
Engineering staff reviewed the proposal and finds the cost reasonable for the scope of services
to be provided. Strand was chosen due to their significant experience within the Sawyer Creek
watershed. This experience includes preparing the original SWMP for the Sawyer Creek
watershed and designing and providing construction -related services for projects within the
Sawyer Creek watershed, including the James Road Area Detention Basin, Westfield Street
Bridge Reconstruction, and the Sawyer Creek dredging project.
BUDGET
The cost of these service is not to exceed $182,500. Funding for these services is included in the
Storm Water section of the 2017 Capital Improvements Program.
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a
specialized nature, including engineering services, may be procured without the use of formal,
sealed quotes. I have reviewed this agreement and in accordance with Section 12-16 of the
Code, I am hereby recommending that the Common Council approve the award of this
engineering services agreement.
