Leemon Ometrotransit.ora) Cc: Leverett, Chris (chris.leverettOkimley-horn.com); Rasmussen, Lisa (lisa.rasmussen0kimley- horn.com) Subject: Ramsey Station - Snow Melt Boiler Building Tim/Kurt/Mark, We have been diligently pursuing the design of the snow melt system and working on the design of a vault on the north side of the tracks (Ramsey City Hall side). We have met with the moving company to make sure that our design does not preclude the ability to move the old Ramsey Town Hall Building at a later date. In addition, we have met with the contractor to talk about how to construct and to get an order of magnitude cost on the building. The status of our efforts is this: we do not believe that we can make this location work for a reasonable cost. Our contractor believes that the cost to locate this building and associated piping will definitely exceed $500,000. The reasons are as follows; • To allow for proper vertical clearance for the boilers and allowance for future installation of a building on top is driving the vault deeper than anticipated. We are now down 12-14 feet and will need to dewater in order to construct the vault. • Due to the depth of the vault, we will need to drive sheet pile on the north side to keep Veteran's Drive in place. In addition, we are getting close to a storm sewer line on the north side and an underground power line on the south side that will require sheet pile on that side as well. • Due to the depth of the vault and the water table at the site, we will need to install waterproofing under the bottom slab in addition to waterproofing in the walls. This waterproofing will required the construction of a "mud mat" (i.e. concrete mat) under the vault before starting construction of the vault. • In order to provide the supply and return lines to the junction box on the platform, the hot water lines will virtually need to "snake" through electrical, communications, storm sewer lines as well as avoid the footing of the skyway pier and miss the existing bus shelter platform and concrete slab while not getting too close to Veteran's Drive. This alignment is further complicated in that it is the area where the contractor is performing most of his last minute work and is the "front door" to the station. If this is not completed by opening, we will have a major mess for the public. • All of this work would need to be performed using winter conditions. This is further driving up the cost and the complexity of the project. Our proposal is to locate the building on the south side of the tracks in an area that has minimal current construction and provide an above -ground building that only needs to meet the needs of the snow melt system. This includes: • A smaller building footprint (likely 20 feet x 20 feet in lieu of 20 feet by 25 feet). This will keep the project costs down.
