3.01 INSTALLATION SEASON
A. Unless otherwise permitted, green wall installation shall be done between April 1 and October 15, or when the outside ambient temperature is not below 10°C.
3.02 INSPECTION AND PREPARATION
A. Before beginning the installation, the owner’s representative and the contracted installer’s representatives must inspect and approve the wall conditions, including the waterproofing membrane, drainage routes, construction joints, etc.
B. The area to be greened shall be a smooth and even surface.
C. The area shall be thoroughly cleaned of debris that might interfere with the installation of frame.
D. Examine finish surfaces, grades and wall quality. Do no start wedge anchor installation work until unsatisfactory conditions are corrected.
E. In the event of non-compliance, a notice is to be provided to the contractor listing the corrective action to be taken. Starting the work will be taken to signify approval of the work conditions.
F. Ensure that all waterproofing, plumbing, woodworking and other work has been duly completed.
NOTE: Retain the following item for warranty.
3.03 SUPERVISION OF WORK BY CONTRACTOR
A. The building envelope contractor must supervise the installation of the Green Wall Panels System to ensure that no damage occurs to the wall that could affect the waterproofing warranty.
B. Immediately notify [the consultant] and [the owner] in writing in case of damage to the wall.
3.04 METHOD OF INSTALLATION
A. Install access scaffolding according to the safety guidelines and requirements as dictated by the local, regional, state or federal building council.
B. Ensure that the work site ambient temperature is at least 10°C and that the site ambient temperature is high enough after the vegetation is installed to prevent frost damage.
3.05 WORK EXECUTION RECOMMENDATIONS
A. Maintain equipment and tools used to install the Green Wall Panels in good condition.
B. Ensure that during use of equipment and tools, watertightness of the wall will not be compromised in any way.
3.06 FRAME & WEDGE ANCHOR INSTALLATION
NOTE: Coordinate with the original building envelope contractor to ensure that the watertightness of the wall will be maintained with the Green Wall Panels System installed.
No bolt installation should take place below -10°C (14°F). Make all efforts to ensure that installation takes place under dry conditions.
A. Prepare the surface.
1. Clean wall surface. Repair any cracks in the concrete and receive approval from a structural engineer that crack repair is sufficient to allow installation of Green Wall Panels System.
B. Install Frame
1. POSITION BOLTS: Begin by marking the starting frame area on the wall and the first bolt position as dictated on the frame drawings.
2. DRILL HOLE: Using an impact drill, drill a 5/8” hole 2 ½” deep when using WA:12700 and a 7/16” hole 1 ¾” deep when using WA:38334.
3. CLEAN HOLE: Clean the hole with a brush and then blow it out with a purging pump.
4. INSTALL ANCHOR: Drive the anchor into the hole until the surface collar is reached.
5. MARK FRAME BOLT PLACEMENTS: Position corresponding GW:FRxx to installed anchor and mark the next bolt placements.
6. INSTALL REMAINING ANCHORS: Repeat steps 2~4 for remaining bolt holes on frame.
7. INSTALL NEOPRENE WASHERS: Slide neoprene washers, GW:NPW12, over the installed wedge anchors.
8. ATTACH FRAME: align frame, slide over anchors and secure to anchors using supplied washer and bolts.
9. Repeat steps 1~7 for all frames.
3.07 PANELS AND IRRIGATION INSTALLATION
1. Feed GW:TLCV6025 line (part of irrigation kits) header from irrigation water source and control box to the base of the first panels to be installed.
2. Install a single planted panel to a frame and install PVC header line along side of panels.
3. Cut irrigation PVC header line and install a PVC Tee to feed GW:TLCV6025 along the top of the panels.
4. Cut GW:TLCV6025 line to leave 70mm of open line inbetween first emitter and GW:TLMLA connection to the end of the cut GW:TLCV6025.
5. Attach the assembled GW:TLMLA + GW:TLCV6025 to the PVC Tee.
6. Run GW:TLCV6025 line inside the top irrigation line groove of the planted panels.
7. Continue to install panels and feed irrigation line into the top groove until the end of the wall section is reached.
8. If the end of the wall section does not connect with another irrigation header line (see detailed irrigation spec), cut and double-back the line 70mm with GW:TL8.
9. If the end of the wall section connects with a header line, install header line Tee insert to GW:TLMLA and connect.
10. Repeat Steps 2~8 until all panels are installed.
(Note: the last line of panels irrigation header to drip line must be attached using a elbow insert and not a T insert.)
3.08 CLASP INSTALLATION (Optional)
1. Using included bolt and nut, align clasp to top of frame and attach GW:CLASP along the top line of planted panels to frame to secure panels from lifting.
3.09 GUTTER INSTALLATION (Optional)
1. Insert two typical gutter securing brackets onto the bottom edge of planted panels so as to fit the length of each elevation of panels. Insert at least one gutter securing bracket per every 3 panels.
2. Cut, cap and/or couple gutter to fit each elevation of panels, use typical eave gutter material.
3. Attached a downspout from the gutter to the designated drainage area as dictated by the drawings to expel water.
4. If necessary attach downspouts from one gutter to the next on cascading elevation systems.
NOTE: Due to the several drainage options, this is only a suggested option for a system without an additional drainage system built below the panels.
3.10 POST-INSTALLATION IRRIGATION AND INSPECTION PERIOD
A. The required Green Wall maintenance contract maintenance begins the day that plants arrive on site. The period between plant arrival on site and completion of the wall is known as the “Build-Out Maintenance”. The 4 week period immediately after completion is known as the “Transition Maintenance”. It is during these times that the plants are most vulnerable and require frequent visits by maintenance personnel to the site. During these periods, uninhibited access to the site must be provided by the Owner. After the “Transition Maintenance” period, “Regular Maintenance” will begin and the terms of the signed and entered maintenance contract will be in effect.
3.11 ACCEPTANCE
A. Inspection to determine acceptance of installation will be made by the Owner, upon Contractor’s request. Provide notification at least seven (7) working days before requested inspection date.
B. Upon acceptance, the Owner will assume maintenance tasks unless a maintenance contract is entered into forthwith.
3.12 CLEANING
A. Perform cleaning during installation of the work and upon completion of the work. Remove all excess materials, debris and equipment from the site. Repair any damage that has resulted from installation. .
NOTICE: G-Sky reserves the right to alter the composition and conditions of use of its materials without notice as knowledge and techniques evolve.
