PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	Verify that conditions are dimensionally correct and within allowable tolerances.
C.	Verify that anchoring surface is in accordance with approved shop drawings.
D.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installation. Surfaces must be clean and dry.
B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
C.	Surface Preparation: 
1.	Clean overall storefront framing and glazing and dry thoroughly prior to grid installation. 
2.	Immediately prior to grid installation use silane treatment for prepping the glass surface at contact surfaces before application of grid system. 
3.	Mix silane concentrate with alcohol and water solution in accordance with the manufacturers instructions before application.
3.3	INSTALLATION
A.	Install in accordance with manufacturer's instructions.
B.	Fabricate grid sections in accordance with the approved shop drawing.
C.	Install perimeter grid before the intermediate grid.
D.	Erection Tolerances:
1.	Limit variations from plumb and level:
a.	1/8 inch (3 mm) in 10 feet (3 M) vertically.
b.	1/8 inch (3 mm) in 20 feet (6 M) horizontally.
2.	Limit variations from theoretical locations: 1/4 inch (6 mm) for any member at any location.
3.	Limit offsets in theoretical end-to-end and edge-to-edge alignment: 1/32 inch (2 mm) from flush surfaces not more than 2 inches (51 mm) apart or out-of-flush by more than 1/4 inch (6 mm).
E.	Allow a tolerance of at least 1/32 inch (2 mm) at all profile intersections.
F.	Verify that glass surface is clean and uncontaminated.
G.	Apply the tape to the Perimeter Grid using 1/2 inch 3M VHB Tape. Dog-ear the backing of the tape on one end of the Grid. Apply the Grid to the glass where desired. Once in place, pull the backing of the tape off while holding the Grid in place. Using a roller, apply pressure to entire length of grid. To achieve a good bond, tape must be applied with a minimum of 15 psi of pressure. Note that grid may require 2 or 3 times that much pressure for the tape experience the required 15 psi minimum pressure required.
H.	After installing the Perimeter Grid, install the Intermediate Grid in accordance with the approved shop drawings. Apply Intermediate Grid using the same process as Perimeter Grid.
I.	Align grid sections plumb and level, free of warp or twist. Maintain dimensional tolerances and alignment with adjacent Work.
J.	Separate dissimilar materials at contact points, including metal in contact with masonry or concrete surfaces, with bituminous paint or pre- formed separators to prevent contact and corrosion.
K.	Adjust grid if required within 15 to 30 minutes of initial application with tape fasteners to glass substrate prior to curing of tape in accordance with the tape manufacturer's instructions. 
L.	After Field Quality Control Inspection apply sealants between intersecting grid for tape applied grid. Sealant color to match muntins. Wipe off excess material and leave all exposed surfaces and joints clean and smooth.
3.4	FIELD QUALITY CONTROL
A.	A senior experienced representative of the installer shall inspect muntins for firm adhesion of tape fasteners to glass substrate the same day as the installation and submit a written Certification of finding to the Architect. 
1.	After application, the bond strength will increase as the adhesive flows onto the surface. This flow is faster at higher temperatures and slower at lower temperatures.
2.	Ultimate bond strength can be achieved more quickly (and in some cases bond strength can be increased) by exposure of the bond to elevated temperatures but not exceeding 150 degrees F (66 degrees C) for 1 hour.
3.5	CLEANING
A.	Protect installed products until completion of project.
B.	After installation, remove all sealants, caulking, and other materials from all surfaces, including adjacent work.
C.	Remove temporary coverings and protection of adjacent work areas. Repair or replace damaged installed products.
D.	Thoroughly clean window frames, casings, and glass using materials and methods recommended by the window and glass manufacturer that do not cause defacement of work.
E.	Remove construction debris from project site and legally dispose of debris.
3.6	PROTECTION
A.	Protect installed products until completion of project.
B.	Protect aluminum from damage from grinding and polishing compounds, plaster, lime, acid, cement, or other harmful contaminants. 
C.	Touch-up, repair or replace damaged products before Substantial Completion.
