January 18, 2013 Page 2 of 5 Pequot Lakes and Ideal Township Nelson Road Improvements Proposal • We understood that both entities believed the sub -grade (material below the aggregate base) in this area is suitable for use as roadway base and requested a 10 -ton pavement ! structural design. The suggestion was that the roadway section consists of 5 inches of Class 5 under 2 -1/2 inches of bituminous pavement. Based on this assumption, we would anticipate the Class 5 shoulders will be 7 -1/2 inches to match the structural pavement thickness. We recommend a pavement structural design be completed to determine the final roadway section. This type of design would take into consideration average daily traffic counts, vehicle size distribution, and sub -grade soil strength (R- value). This service is not included in our proposal, but if desired, we can provide this as an additional service. • We do not see the centerline alignment changing to a significant degree. If anything, the centerline may shift to the west a bit due to the steep slopes along the east side. • The desire is to clear and grub the entire RMf width. This will be a detail, though, that will need to be coordinated with grading and other design features. • This project will include improvements to short segments of Wild Acres Road on either side of its intersection with Nelson Road. • This project will include improvements to a short segment of Akerson Road as it comes down the hill to its intersection with Nelson Road and Buschmann Road. • At the Nelson Road — Ackerson Road — Bushmann Road intersection, the design will include a reduction of pavement area and better edge definition (eliminate pavement in the northeast corner and along the south side of the present intersection and potentially replace these areas with shallow infiltration basins). • Based on our very preliminary review of the project (obviously, there has been no design done yet so that a cost estimate could be prepared using estimated quantities of work), the project may cost $75 or more per lineal foot. With approximately 5,000 feet of construction, a very preliminary construction cost estimate would be in the neighborhood of $375,000. We recommend the City and the Township include contingencies (10% at this stage) in their budgeting. A better cost estimate will not be known until a design is prepared. • With such a cost, the project will exceed requirements for the quoting process, and an engineered set of construction drawings suitable for public bidding would be prudent. WSN proposes the following scope of services: I. Field Survey & Utility Locations After appropriate office research and a Gopher One Call, a field survey $3,950 will be completed to provide topographical information and to pick up utility locations.
