<br /> <br />024110.1 – SELECTIVE DEMOLITION <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 />SECTION 024110 <br /> <br />SELECTIVE DEMOLITION <br /> <br />PART 1 GENERAL <br /> <br />1.01 WORK INCLUDED <br /> <br />A. Perform a Pre-Job Damage Survey prior to the start of work on-site including mobilization of <br />equipment, material delivery, and set-up of storage and staging areas. <br /> <br />B. Water test underground drain lines prior to the start of demolition for roof replacement to confirm <br />that they appear to be in working order (not clogged or damaged in a way that causes the back-up <br />or slow flow of draining water from downspouts). <br /> <br />C. Provide labor, materials, equipment, and supervision necessary to perform selective demolition, <br />which includes, but is not limited to the following: <br /> <br />a. Remove existing asphalt shingles, underlayment, perimeter edge metal, gutters, fascia, soffit, <br />downspouts, and support framing at the soffit/overhang to expose the existing oriented strand <br />board substrate. Care must be taken to avoid damage to the existing substrate during removal <br />of the existing roofing. Sequence the work so that crews do not remove more of the existing <br />roof system than can be maintained in a watertight condition prior to the end of each <br />workday. Removed materials should be disposed of legally off-site unless otherwise agreed <br />upon with the Owner. <br /> <br />b. Remove the EIFS (coating and insulation) to expose the sheathing along transitions with the <br />adjacent shingled roof system and directly below all window/louver assemblies on the south <br />elevation. <br /> <br />c. Protect components that will remain for reuse, including, but not limited to, nailable <br />substrate, portions of wood blocking, portions of the EIFS, sheathing, masonry walls, <br />windows, penetrations, louvers, etc. <br /> <br />d. Inspect the existing oriented strand board substrate, wood blocking, sheathing, and other <br />components noted to remain. Make repairs to, or replace, damaged or deteriorated materials <br />in accordance with applicable sections of these specifications. Protect and reuse existing <br />wood blocking and cold-formed framing only where shown on the design details or when <br />specifically approved on-site by the Designer. Otherwise install new materials. Inspect the <br />securement of the existing oriented strand board and install supplemental fasteners in <br />accordance within applicable sections of these specifications to provide wind uplift resistance <br />in accordance with the North Carolina State Building Code and ASCE-7. Refer to base bid <br />allowances (estimated quantities of work in Section 012100) for additional information. <br /> <br />e. 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 />DocuSign Envelope ID: 9514E4EC-C3C9-4752-8A7F-22E83B22BB8E
