sodpodmod® Pre-Vegetated Modular Green Roof Delivery System
extensive green roof system
(Note to Specifier: Please delete prior to publication:
The sodpodmod modular Green Roof delivery system may be purchased as a recycled cardboard tray and shipper only and supplied to the Landscape Contractor. The Landscape Contractor should follow the instructions for providing nursery supported green roof plantings until such time the modules are required at the construction site for installation on the rooftop. The Contractor then takes responsibility for the receipt of the modules at the construction site, and the Landscape Contractor can complete the installation and provide all required warranties. Landscape Architect approves all design and plantings per Construction Documentation and details.)

PART 2 – PRODUCTS
A. sodpodmod® system includes a recycled corrugated cardboard tray, roughly 16” X 16” X 3” deep, an optional drain board that fits inside the tray, and a shipper module that the tray and drain board (with growing media and 80% established native plants) fit inside. The shipper module is tabbed for stacking on a palette for loading into a semi truck for delivery to a site.
B. Recycled Corrugated Cardboard Tray: Custom-made re-cycled cardboard box with drainage at bottom; certification required from manufacturer.
1. sodpodmod® module size: 16” X 16” X 3” deep = 1.71 SF per sodpodmod.
Custom sizes available upon request.
C. Re-cycled cardboard insert for bottom of tray to contain the growing media and prevent loss of growing media from tray.

PART 3 – EXECUTION
3.1. SODPODMOD® MODULES DELIVERY AND HANDLING
A. All sodpodmod® modules are designed to be installed within 24 hours after receipt of delivery at job site.
B. Do NOT deliver to jobsite when temperatures exceed 85 degrees F. or fall below 45 degrees F. without specific instructions and technical assistance from sodpodmod LLC.
C. Do not deliver sodpodmod® modules in conditions where weather would create a danger to the installation. Monitor schedules for appropriate conditions for viable delivery, with live pre-vegetated growing modules maintained throughout truck delivery to the site, delivery to the job-site roof, and installation of the sodpodmod® modules on the roof membrane installation.
D. Handle sodpodmod® modules with care and keep moist upon installation to prevent excessive shock to plant material and lack of moisture.
3.2. SITE PREPARATION & INSTALLATION
A. Thoroughly sweep away all debris, foreign material, etc. from the completed and inspected waterproofed surface. Do not install sodpodmod® until waterproofing system has passed all required field tests.
B. Install suitable slip sheet or filter fabric protection fabric where required as per waterproofing system manufacturer’s recommendation.
C. Cover roof garden drains with a perforated drain box with removable lid and set at height of the top of the sodpodmod® module. Install gravel at the perimeter of parapet roof to edge of first sodpodmod® module.
1. Tolerances: Minimum of 6” from roof parapet edge; not to exceed 12 inches.
D. Foot traffic shall be supported by separate paths of growing media, however the sodpodmod® modules themselves can support individual foot traffic.
E. Installation may be started by setting up individual starter courses from the lower slope of the roof and progressing upward to the upper levels. Individual sodpodmod® placement shall be tightly nested with no gaps between the modules. The finished vegetated field of the green roof must appear natural.
A. Perform cleaning during installation of the work and upon completion of the work.
B. Remove from site all excess materials, debris, and equipment.
