010100.2 –SUMMARY OF WORK <br /> <br />Project Manual for Motor Pool Main Building Roof Replacement <br />Orange County, Hillsborough, NC <br />Prepared by Atlas Engineering, Inc., 551-A Pylon Drive – Raleigh, NC 27606 <br />August 2021 <br />6. Inspect the existing oriented strand board, wood blocking, sheathing, and other <br />components noted to remain. Make repairs to, or replace, damaged or deteriorated <br />materials in accordance with applicable sections of these specifications. Protect and reuse <br />existing wood blocking and cold-formed soffit support only where shown on the design <br />details or when specifically approved on-site by the Designer. Otherwise install new <br />materials. Inspect the securement of the existing oriented strand board and install <br />supplemental fasteners in accordance within applicable sections of these specifications to <br />provide wind uplift resistance in accordance with the North Carolina State Building Code <br />and ASCE-7. Refer to base bid allowances (estimated quantities of work in Section <br />012100) for additional information. <br /> <br />7. Inspect roof penetrations and raise/extend penetrations as needed so they will maintain a <br />minimum 8” vertical flashing height above the shingled roof at the new roof thickness. <br />Extend/modify any mechanical connections, ductwork, etc. as necessary to raise <br />penetrations to required heights. <br /> <br />8. Inspect existing securement of wood blocking that will remain in use. Install <br />supplemental fastening of existing blocking as noted on the drawings to ensure adequate <br />wind uplift pressure resistance. Install new wood blocking where shown on the drawings <br />to form the roof perimeter and accommodate the new thickness of the roof system. <br /> <br />9. Base Bid: Install and mechanically fasten a layer of nail base insulation (rigid insulation <br />with factory adhered plywood substrate) directly over existing OSB. Secure in <br />accordance with the manufacturer’s requirements and Section 073113, Item 3.02 in this <br />project manual. <br /> <br />10. Alternate Bid #1: Install and mechanically fasten a layer of vented nailbase directly <br />over the existing OSB. Secure in accordance with the manufacturer’s requirements and <br />Section 073113, Item 3.02 in this project manual. Trim/adjust the vented nailbase along <br />eave and high eave perimeters to allow for installation of vented details. <br /> <br />11. Install self-adhered ice and water shield around all eaves, rake edges, high eaves, ridges, <br />and penetrations including at transitions with adjacent walls. Install specified <br />underlayment over the remainder of the roof area and provide proper laps with self- <br />adhered membrane and perimeter metal. <br /> <br />12. Provide and install counterflashings, sheetmetal flashings, cleats, fascia, soffits, cold- <br />formed support framing, wall panels, trim, gutters, downspouts, straps, and other <br />sheetmetal trim and sealants as shown on the drawings for proper installation of the <br />design details. Wall panels shall be installed on support framing to cover all EIFS areas. <br />At areas of EIFS removed beneath window assemblies and at transitions with the <br />adjacent shingled roof, install self-adhered underlayment over sheathing and foil faced <br />polyisocyanurate insulation to match the thickness of the adjacent EIFS before <br />installation of supports and wall panels. Install pre-fabricated gutter guards at all gutters. <br /> <br /> <br />13. Install new asphalt shingled roof system on all roof areas including vented eave and high <br />eave/ridge details if Alternate Bid 01 is selected. Install metal flashings where the <br />DocuSign Envelope ID: 9514E4EC-C3C9-4752-8A7F-22E83B22BB8E
