4 WATTS ENGINEERS, PLLC 4876 US 64 Morganton, NC Phone (828) Fax (828) June 29, 2018 Red Bike Architecture, PLLC Mr. James M. Ratliff P.O. Box 574 Rutherford College, NC RE: Job #201740, Lincoln County Tax Appraisal Office, 100 East Main Street, Lincolnton, NC Following are our recommendations for the steps to be taken to ensure uninterrupted operation of the county s computer servers during this renovation/alterations project. 1) Install a plastic sheeting (min. 6 mil) complete enclosure around/above the servers and seal all seams with sheathing/building type seam tape. Include a zippered entry door (zip door) in the enclosure so that county IT employees can access the servers at any time. Consult with the county IT manager to determine the minimum enclosure dimensions so that free, working access to all sides of the servers is possible while inside. The enclosure shall be in place prior to the start of the work. 2) The existing return grill/duct in the server room from the existing rooftop air handler (E- AHU) should be removed prior to other work in the area so that dust is not drawn into the E-AHU. 3) Existing Zone 3-6 from E-AHU should initially be demo ed back to just where it enters the server room. From that point a temporary 16 round flex duct should be connected and routed to provide air conditioning to the servers inside the enclosure. Consult with the county IT manager to determine the best location for the attachment of the 16 supply air (in case direct cold air impingement against the servers is undesirable). Attach and seal the 16 flex to the enclosure material in a secure fashion. 4) Once the enclosure is sealed and air is being introduced into via the 16 flex duct, the mechanical contractor (MC) will most likely find that the zipper door will need to be left open a certain amount in order for the entering air to have a means of relief. To determine the proper amount the zipper should remain open, the MC shall simply adjust the zipper position so that the pressure inside the enclosure does not reach levels that would compromise the sheathing tape or the enclosure itself. 5) In the case that someone needs to enter the enclosure during construction, it is recommended that all cutting/patching/sanding work cease 30 minutes beforehand. This is due to the loss of pressure (and subsequent increase in the possibility of contamination with duct) that will occur inside the enclosure when the zipper door is fully opened. Please contact me with any questions or comments. Sincerely, WATTS Engineers, PLLC David S. Lane David S. Lane, P.E.
