DocuSign Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> SECTION 01 7- -L UAPRD INRD @BAD EM ENTBANCES ANM STOBECBONTS <br /> / ABT L UE4ECRTION <br /> 3.1 EXAMINATION <br /> A. Examine areas, with Installer present, for compliance with requirements for installation tolerances and other <br /> conditions affecting performance of storefront systems. Do not proceed with installation until unsatisfactory <br /> conditions have been corrected. <br /> 3.2 INSTALLATION <br /> A. General: Comply with manufacturer's written instructions for protecting, handling, and installing storefront systems. <br /> Do not install damaged components. Fit frame joints to produce hairline joints free of burrs and distortion. Rigidly <br /> secure nonmovement joints. Seal joints watertight. <br /> B. Metal Protection:Where aluminum will contact dissimilar metals, protect against galvanic action by painting contact <br /> surfaces with primer or by applying sealant or tape recommended by manufacturer for this purpose. Where <br /> aluminum will contact concrete or masonry, protect against corrosion by painting contact surfaces with bituminous <br /> paint. <br /> C. Install components to drain water passing joints and condensation and moisture occurring or migrating within the <br /> system to the exterior. <br /> D. Set continuous sill members and flashing in a full sealant bed to provide weathertight construction, unless <br /> otherwise indicated. Comply with requirements of Division 07, Section"Joint Protection." <br /> E. Coordinate tie in to buildings water resistive barrier and air barrier systems to ensure system continuity as they <br /> work in conjunction with the window units. <br /> F. Install framing components plumb and true in alignment with established lines and grades without warp or rack of <br /> framing members. <br /> G. Install glazing to comply with requirements of Division 08, Section "Glazing," unless otherwise indicated. <br /> H. Install perimeter sealant to comply with requirements of Division 07, Section "Joint Protection," unless otherwise <br /> indicated. <br /> I. Erection Tolerances: Install storefront systems to comply with the following maximum tolerances: <br /> 1. Variation from Plane: Limit variation from plane or location shown to 1/8 inch in 12 feet; 1/4 inch over total <br /> length. <br /> 2. Alignment: Where surfaces abut in line, limit offset from true alignment to 1/16 inch. Where surfaces meet at <br /> corners, limit offset from true alignment to 1/32 inch. <br /> 3. Diagonal Measurements: Limit difference between diagonal measurements to 1/8 inch. <br /> 3.3 CLEANING <br /> A. Remove excess sealant and glazing compounds, and dirt from surfaces. <br /> 3.4 PROTECTION <br /> A. Provide final protection and maintain conditions, in a manner acceptable to manufacturer and Installer, that ensure <br /> the storefront systems are without damage or deterioration at the time of Substantial Completion. <br /> 3.5 FIELD QUALITY CONTROL <br /> A. Testing Agency: Engage a qualified independent testing and inspecting agency to perform field tests and <br /> inspections. <br /> B. Testing Services: Testing and inspection of representative areas to determine compliance of installed systems <br /> with specified requirements shall take place as follows and in successive phases as indicated on Drawings. Do <br /> not proceed with installation of the next area until tests results for previously completed areas show compliance <br /> with requirements. <br /> 1. Structural Sealant Compatibility and Adhesion: Structural sealant shall be tested according to <br /> recommendations in ASTM C 1401. <br /> a. Destructive Test Method A, "Hand Pull Tab(Destructive)", in ASTM C1401,Appendix X2, shall be used. <br /> 1) A minimum of two areas on each building face shall be tested. <br /> 2) Repair installation areas damaged by testing. <br /> 2. Structural-Sealant Glazing Inspection: After installation of aluminum-framed systems is complete, structural- <br /> sealant glazing shall be inspection and evaluated according to recommendations in ASTM C 1401. <br /> 3. Air Infiltration: Areas shall be tested for air leakage of fixed wall area when tested according to ASTM E 783 <br /> at a minimum static-air pressure difference of 1.57 Ibf/sq.ft. (75 Pa). <br /> G#OODEBAN8 MESI8 N 3-1L5 01 7- -L U5 5-0 Deadowlands Mrive,Hillsborough, NC <br /> OBAN8 E CORNTY,NC --2 521 <br />
