<br />010100.3 –SUMMARY OF WORK <br /> <br />Project Manual for Whitted Building Roof Replacement <br />Orange County, Hillsborough, NC <br />Prepared by Atlas Engineering, Inc., 551-A Pylon Drive – Raleigh, NC 27606 <br />May 2022 <br /> <br />3. Test all drains/underground drainage for free flow prior to beginning of work. Clogged or <br />blocked drains/pipes shall be reported to the Owner. <br /> <br />4. Adjust the existing drain heights and add extensions as necessary to provide proper <br />installation of the new roof system on Roof Areas C, E, and F. <br /> <br />5. Install 8 new 3″ diameter primary drains on Roof Area B with a 4’ drain sump. The new <br />primary drains should be set on the existing wood deck. Core the existing roof deck to <br />allow for installation of a new 3″ I.D. vertical drain line, and transition to a 3″ I.D. <br />horizontal drain line within the existing attic space. The new primary drain lines should be <br />located around the perimeter, 4’ from the parapet wall, and at the same location of the <br />existing parapet wall scupper openings. Core through the existing exterior masonry wall to <br />allow for the horizontal drain line to run from the interior attic space out to a copper <br />conductor head and downspout. The downspout should be located at the same location as <br />existing downspouts and run into existing underground storm drainage where applicable. <br />Locate the conductor head within the flattest section of the existing exterior cornice and <br />remove trim as necessary. Ensure all conductor heads are located at the same elevation <br />around the building. Verify locations and layout with Designer prior to installation. <br /> <br />6. Install 8 new 4″ diameter secondary drains on Roof Area B. Do not sump or shave <br />insulation around overflow drain. The new overflow drains should be set on wood blocking <br />on the existing wood deck. Core the existing roof deck to allow for installation of a new 4″ <br />I.D. vertical drain line, and transition to a 4″ I.D. horizontal drain line within the existing <br />attic space. Core through the existing exterior masonry wall to allow for the horizontal <br />drain line to run from the interior attic space out to a drain nozzle/lamb’s tongue. Locate <br />the lamb’s tongue centered within the flattest section of the existing exterior cornice. <br />Ensure all lamb’s tongues are located at the same elevation, and equal spacing from the <br />new primary drain outlets/downspouts around the building. Verify locations and layout <br />with Designer prior to installation. <br /> <br />7. Replace any damaged wood deck on Roof Areas A and B. Inspect the existing wood deck <br />in these areas and restore/replace rotted wood deck. Notify Designer of any areas requiring <br />replacement. <br /> <br />8. Inspect the existing metal deck and restore/replace corroded metal deck on Roof Areas C, <br />D, E, and F. Notify Designer of any areas requiring replacement. <br /> <br />9. Install new nailers along parapet walls on all roof areas and along the gutter/perimeter edge <br />on Roof Areas A, D, and F to meet the specified requirements. If existing wood blocking <br />is present, notify the Designer, and inspect any existing wood blocking. Replace at <br />locations where existing materials are damaged, deteriorated, warped, or do not meet the <br />specified requirements. Verify any wood blocking to remain is properly secured to the <br />existing structure. Provide supplemental fasteners if necessary. <br /> <br />10. Install plywood on the interior of all parapet wall with fastening to meet the specified <br />requirements. <br /> <br />DocuSign Envelope ID: 89558C18-938A-4BFF-B14A-A2214E8AA5DD
