Applicant Responses <br />Screening: <br />1. The project budget included a basic shadowbox type screening fence with an allowance of <br />$8500. In our subsequent discussions with the City of Ramsey we have come to understand that <br />this is unacceptable. Thus, we next discussed on site with Tim Gladhill a metal fence with <br />landscaping. The metal fence with landscaping could be accommodated with the same $8500 <br />screening in the project. From the most recent e-mail pertaining to the City Zoning Code, we <br />understand that the city is requesting analysis of a screen wall of "similar material to the <br />building". We have developed a concept for an architectural screen wall, of similar materials to <br />the building, that will completely screen the equipment from Sunwood Drive. Our estimated <br />cost for this, including design and all associated costs, is approximately $27-$30K. This <br />represents a net increase to the project of approximately $21,500. <br />2. To the best of our knowledge, there is already an agreement in place with NAU Country as <br />regards the landscaping maintenance. <br />Location and Design of Chillers and Tanks <br />1. There are five primary mechanical components to be located outside — two (2) air cooled <br />chillers, one (1) drycooler, one (1) duplex pump set and one (1) storage tank (150 gallons <br />volume). The weights and PSF loading of these components are as follows: <br />a. Air cooled chiller — 752 lbs operating weight — 41 PSF loading <br />b. Drycooler — 685 lbs net weight — 4.8 PSF loading <br />c. Duplex pumps set — negligible <br />d. Storage Tank — 2150 lbs operating weight — 304 PSF loading <br />2. This project requires that this new mechanical equipment be installed, started up, tested and <br />commissioned prior to demolition of any of the existing equipment that is already on the roof to <br />avoid a costly extended outage to the data center. <br />3. Note - the existing equipment already occupies the "best" structural locations on the roof. This <br />can observed in that the existing equipment is lined up in the middle of the roof — straddling the <br />structural beam under the roof. <br />4. Thus, even if the structural beams on the roof can support the new equipment, those locations <br />are already taken with the existing mechanical equipment and it is not logistically possible to <br />stage the new equipment in prior to demolition of the existing equipment. <br />5. The project has thus chosen a direction to locate the new equipment on grade, where it can be <br />installed, start-up, tested and commissioned without affecting the existing equipment. <br />
