1.5 PROJECT CONDITIONS A. Contractor to confirm that the wall behind the living wall system be water tight. B. Engineer shall certify that the structure is capable of bearing the load of a modular living wall system. C. Contractor to provide adequate structural support for planting rails. D. Protect installed rails from damage by adjacent work. D. Planted Tournesol VGM™ Modular Living wall modules should be placed on building only after substantial completion of project to protect plants.

2.0 PRODUCTS Rev. 8/14 2.1 ACCEPTABLE PRODUCTS/MANUFACTURERS A. Tournesol VGM™ Modular living wall planting modules, mounting rails and brackets, manufactured by Tournesol Siteworks LLC. 30955 San Antonio St., Hayward, CA 94544 Tel: (800) 542-2282 FAX (510) 471-6243

2.20 LIVING WALL MODULES A. Materials – All module elements shall be constructed of 100% post-consumer recycled black polypropylene, and shall have a black synthetic non-woven soil retention bag. B. Construction – Modules shall be constructed to allow maximum air penetration from the back and sides, ship unassembled for reduced freight cost, and snap together for quick assembly at the nursery. The units will have 16 openings across the front to support the planted soil retention bag, with supplemental retention bars to prevent soil erosion. D. Finish: black factory finished. E. Sizes: Modules to be 18.75”w x 22”h, either 6”thick (with 4” planting depth) or 10” thick (with 8” planting depth). Other depths may be fabricated as required.

2.21 LIVING WALL MODULE BRACKET A. Materials – All module brackets shall be constructed of 304 stainless steel and shall be powder coated. B. Construction – Brackets will be made as right and left side bracket, of sufficient strength to support a 250lb. load. D. Finish: Black powder coated. E. Sizes: To fit living wall modules. Brackets specifically manufactured for in right and left sides for both VGM-10 and VGM-06 module depths.

2.22 LIVING WALL MODULE RAIL A. Materials – All module rails shall be constructed of 304 stainless steel. B. Construction – Rails shall have double slot module mounting holes, and wallmount holes along the rail. C. Finish: Natural stainless steel. D. Sizes: Rails to hold 1 (23-5/8”), 2 (47-1/4”) or 3 (70-7/8”) modules. Other sizes achieved by combining rails together.

2.23 LIVING WALL PLANTING MEDIA A. Materials – Sponge-like media composed of a proprietary blend of composted organic materials, enhanced with natural biological and disease-preventing addatives, bound with a proprietary natural binder. B. Construction – Media shall be molded to fit each module (2X for VGM3-06, 4X for VGM3-10), and have sponge-like consistency. Media block shall way approx. 3 lbs when dry, and hold up to 13 lbs of water. C. Size and Finish: Block shall measure 20.5”L x 9”W x 4”H and shall be dark brown with sponge-like surface.

2.3 LIVING WALL ACCESSORIES

Rev. 8/14 A. Anchors – specification by engineer, depending upon the wall construction and local codes. B. Irrigation – design by others. Typical installation utilizes drip irrigation system, with filter, pressure reducer, controller, fertilizer injection assembly. Main tubing running vertically along every other rail, with multi-outlet drip emitters located at each course of modules. Route drip tubing from multi-outlet emitter to top of module (3 tubes per module). C. Irrigation Controller – Remote-monitored irrigation controller with two-wire technology, soil moisture sensor, available from Tournesol Siteworks. Ethernet jack available on irrigation controller, cloud-based monitoring and control available through Baseline Systems. D. Planting Media – specification by others, depending upon location and available components. Typical media utilizes lightweight 93% inorganic mix, largely of calcine clay, expanded slate, sand, perlite or vermiculite. Maximum saturated weight should be less than 50 lbs/cu. ft. Additional water retention materials may be added as required.

3.0 EXECUTION

3.1 PREPARATION A. The living wall modules should be transported, unassembled, to the nursery or location where they will be planted and grown in. Modules should be assembled without top. When using VGM Media Block, take dry media block and pre-saturate before inserting in VGM module. No bag is required, although may be used for situations with high evaporation. When using conventional media, the soil rention bag shall be placed inside and filled with planting media. Care should be taken that bag is as full as possible. Bag is to be folded over, and top attached. Modules should be planted on their back in the nursery, and grown in for 1-3 months. Proper grow-in is essential for retaining plants in modules when they are mounted vertically. B. Contractor to inspect the mounting location, to determine correct positioning of mounting rails, irrigation plumbing. Verify anchors specified will support load, and that wall is sufficiently prepared for Tournesol VGM™ system.

3.2 INSTALLATION A. Mount rails on building or steel structure, starting with end rail and using assembled module with brackets as template for adjacent rails. B. Install irrigation system per plans and specifications prior to mounting planted VGM™ modules. C. Transport planted modules to project site, then install brackets on each module. Start with lowest course, work towards top. Hang bracket/module unit on rail, then install final irrigation tubing prior to moving to next row.
