VEGETATED ROOFSYSTEM
PART 1 - GENERAL
1.1 SCOPE
Furnish all labor, materials, tools, and equipment to unload, hoist and install vegetated roof trays, by
GreenGridO Green Roof System provided by Weston Solutions, Inc. (WESTON), or approved equal.
The System shall include tray modules, growth media and the vegetation as specified on drawings and
as directed by the Landscape Architect. This work shall also include installation of edge treatments,
rubber pavers, decorative ballast, slip-sheet, and an irrigation system, if specified.
1.2 RELATED WORK SPECIFIED ELSEWHERE
A. Roofing Systems—see Architecture specification.
1.3 QUALITY ASSURANCE
A. There should be no deviation made from this specification or the detail drawings without prior
written approval 14 days prior to the start of the project.
B. Before installation of the modules, the waterproofing surface shall be inspected by a technical
representative of the waterproofing installer/manufacturer to determine the adequacy of the
waterproofing surFace to accept the tray modules.
C. It shall be the Owner's responsibility to determine the adequacy of the structure to support the
existing and proposed loads. Verification of the integrity of the waterproofing for water
tightness shall also be the responsibility of the Owner if the green roof is installed on an
existing waterproofing system.
D. Upon completion of the installation, an inspection shall be conducted by a System Technical
Representative to ascertain that the modules have been installed according to these
specifications and details. This inspection is not intended to be a final inspection for the
benefit of the owner but for the benefit of determining whether a warranty shall be issued.
1.4 SUBMITTALS
A. When the proposed project components vary outside of this specification, submit these altered
components for review.
B. Submit an installation plan including but not limited to: waterproofing quality control, system
delivery, and maintenance plan until green roof acceptance.
C. Provide a detailed water hook-up plan on the drawings if an irrigation system is required.
PART 2 - PRODUCTS
2.1 SYSTEM TRAY MODULES
A. Vegetated Green Roof System Tray Modules are formed of 4" height 150 mil recycled (100%
pre-consumer) High Molecular Weight Polyethylene (HMWPE) protected with UV inhibitor and
stabilizers.
B. GreenGridO Modules sizes (Module OD = ± '/8"):
Mary Hart Design LLC 07 7100-1 VEGETATED ROOF SYSTEM
Change Order 4
1. Extensive:
Standard 18"x 24"x4" G3 modules -see L201 plan layout
C. Tray Module to be delivered to the project location complete with growth media and pre-
planted and/or pre-grown to 80% coverage with vegetation of the color and type desired by the
client suitable for a green roof application.
D. Tray Module weights (Bulk density at maximum water holding capacity):
1. Ultra-Extensive System (2.5-inch): 11-13 Ibs per sf
2. Extensive System (4-inch): 18-22 Ibs per sf
3. Intensive System (8-inch): 35+ Ibs per sf
E. Tray Module clearance above the roof is 0.5 inches.
2.2 GROWTH MEDIA
A. Tray Module Growth Media is an engineered light weight blend consisting of inorganic and
organic components. Formulations are based on the German FLL"Guidelines for Planning,
Execution and Upkeep of Green-Roof Sites"
2.3 VEGETATION
A. Tray Modules are to be delivered to the project location complete with growth media and
vegetation pre-planted and/or pre-grown to 80% coverage with plant species desired by the
client suitable for green roof applications.
B. Extensive System—GreenGridO recommended Extensive plant mixes are composed of highly
drought resistant ground covers that can thrive in a non-irrigated (climate dependent), rooftop
environment in the project location. Vegetation shall be jointly selected by manufacturer and
project landscape architect according to their USDA hardiness zone classification.
1. Recommended planting density-Vegetation should be supplied in a minimum size of 2-
inches deep by 1.5-inches wide (plugs)and planted 4 to 6 inches on center(18 to 16
plants per 2x4 module, respectively).
C. Intensive Svstem—_GreenGrid recommended Intensive plant mixes shall include grasses,
perennials, and/or groundcovers that can thrive in an irrigated or non-irrigated, rooftop
environment in the project location. Plants shall be selected according to their USDA
hardiness zone classification.
1. Typical planting density-Vegetation should be supplied in grow-plug or quart size
containers and planted in the GreenGridO green roof modules at a rate of 8 to 12 inches
on center(11 to 8 plants per 2x4 module, respectively).
D. Vegetation shall be installed in accordance with the landscape design
2.4 GREENGRIDO ACCESORIES
A. Rubber Pavers are required
1. Standard Paver size: 2 feet by 2 feet, and 1.75-inches in depth. Various paver depths are
Mary Hart Design LLC 07 7100-2 VEGETATED ROOF SYSTEM
Change Order 4
available.
2. Pavers are composed of 100% recycled (post-consumer) rubber and are available in
various colors.
3. Standard Paver weight: 7.5 Ibs. per square foot.
B. Edge Treatments (optional)
Standard: 0.040 Painted Aluminum (recycled content 91%)or 24 gauge Painted Steel
(recycled content 28 to 35%)for placement on viewable edge of modules.
C. Irrigation Systems (by others)
Irrigation requirements will be dependent upon project location and plant selection. For
Extensive GreenGridO Systems planted with a mix of highly drought resistant ground covers,
a backup system to irrigate the green roof during prolonged droughts or during hot dry windy
weather patterns is to be provided. Simple overhead spray system with spray heads,
or spigot/hose/sprinkler systems are inexpensive and effective methods. These also provide
the means to optimize the evaporative cooling effect of the GreenGridO Green Roof System
during such weather events.
