City of Pequot Lakes WIDSETH Maintenance Dept. Facility Addition SMITH Feasibility Study K NOLTING Page 4 Civil Summary The existing site includes several City services to its citizens: City offices/administration, Police Department, Fire Department, and Maintenance Department(as well as the water treatment plant immediately north of the"City Hall"site). From a Maintenance Department's perspective,this combination of services and visibility to the public with on-going operations can be challenging at times. The Maintenance Department has an accessory garage and a salt storage shed(lean to)as well as material storage towards the north end of the site. With increased road mileage and maintenance responsibilities,the existing salt storage shed would be removed and a new larger salt storage building would be constructed. It would either be `stick built',a similar structure used by other comparable size communities, or it would be a concrete side wall—fabric dome type,used by some public works' entities. The accessory garage is to remain and would have some minor refurbishment to continue its usefulness. With the increased roadway mileage and corresponding equipment and material responsibilities,while the present site is workable, it will become relatively tight. There are only a few options for siting the new salt storage structure while maintaining the needed turning radii and working space. There are currently holding tanks for the floor drain system in the main building(towards the northeast side)and the accessory garage(north side). The owner has stated there have been freezing problems in the piping to the holding tank north of the accessory garage and would like to extend the drain piping from the accessory garage to a new holding tank for the main building east of the addition. This would entail removal of existing bituminous and excavation to extend drain piping and facilitate having one wastewater service line connection should a sanitary sewer main become available in the future. Structural Summary Existing Exterior North Wall: North end exterior wall is comprised of 5 steel columns(A, B, D,F, G)spaced at 16' or 24' along column line 12. An exterior overhead door not shown on the original plans was add at the northwest corner between columns A and B. Manufactured building(Butler)drawings are not available to confirm the vertical bracing that is present at the north end wall but likely present between two of the existing columns to transfer horizontal wind loads to the foundation. Existing bracing will need to remain or the new building addition designed to continue the existing roof bracing to the addition north wall and adequate vertical bracing design for both existing and new building horizontal wind loads. Existing foundation system along column line 12 (existing exterior north wall) is a continuous concrete strip footing with two#5 reinforcement bars. The foundation system is adequate to support new roof/building loads transferred to the existing columns. Existing columns may require reinforcement in the Y-Y axis with the purlins removed and costs have been allocated for this minor structural work. Mechanical Systems Summary Plumbin&: Plumbing fixtures appear to be in good condition.
