Civil Engineer City of Arden Hills 1245 West Highway 96 Arden Hills, MN 55112-5743 RE: Proposal for Professional Engineering and Surveying Services CP Rail Trail Underpass Improvements City of Arden Hills, Minnesota Project No.: Tl 6.1 00325 Dear Ms. Giga: Weare pleased to offer you our proposal for professional engineering and surveying services for the final design of the CP Rail Trail Underpass Improvements along Old Highway lOin Arden Hills. This proposal is based on those improvements described in our December 2008 Preliminary Engineering Report for the Old Snelling A venue/ Old Highway 10 Trail, which was presented to the City Council on December 8, 2008. As a part of this proposal, we describe our understanding of the project, detail our proposed scope of \vork, and provide our fee for completing the work. Final Design Services As a part of the Preliminary Engineering Report for the Old Snelling A venue/ Old Highway 10 Trail, Bolton & Menk discusses the possibilities of constructing a trail along Old Highway 10 with an underpass crossing the existing CP Rail bridge. The recommended approach is to construct a bituminous trail crossing under the bridge, between its piers and abutment. This approach would require the construction of retaining walls at the crossing and along the north and south approaches to the crossing. The crossing is illustrated in Figure No. 15 of the preliminary engineering report. At this time, it has not been decided on which side of Old Highway 10 the underpass will be constructed. However, design and construction of the underpass relative to each side of the roadway is expected to be similar. Once the desired side of the roadway is selected for the underpass, Bolton & Menk will complete the necessary topographic survey, final design and engineering required to prepare final construction plans and specifications for contractor bidding. The topographic survey will be completed from the road edge or curb to a point approximately thirty feet outside the road, and will extend approximately 200' to the north and 200' to the south of the rail bridge. Locations and measurements of the applicable above-grade geometry of the rail bridge, including the piers, abutments, clearance heights, etc. will also be recorded to facilitate the underpass design. A Gopher One Call will also be initiated to identify any underground utilities within the project area. Bolton & Menk, along with LHB as its structural engineering subconsultant, will prepare detailed construction plans in CAD illustrating plan and profile views of the underpass and its approaches (up to 200' in each direction). Cross sections win also be shown along with
