PART 3 - EXECUTION

3.1 INSTALLATION, GENERAL

A. Install roof specialties according to manufacturer's written instructions. Anchor roof specialties securely in place, with provisions for thermal and structural movement. Use fasteners, solder, protective coatings, separators, underlayments, sealants, and other miscellaneous items as required to complete roof-specialty systems.

1. Install roof specialties level, plumb, true to line and elevation; with limited oil-canning and without warping, jogs in alignment, buckling, or tool marks.

2. Provide uniform, neat seams with minimum exposure of solder and sealant.

3. Install roof specialties to fit substrates and to result in weathertight performance. Verify shapes and dimensions of surfaces to be covered before manufacture.

4. Torch cutting of roof specialties is not permitted.

5. Do not use graphite pencils to mark metal surfaces.

B. Expansion Provisions: Allow for thermal expansion of exposed roof specialties.

1. Space movement joints at a maximum of 12 feet (3.6 m) with no joints within 18 inches (450 mm) of corners or intersections unless otherwise indicated on Drawings.

2. When ambient temperature at time of installation is between 40 and 70 deg F (4 and 21 deg C), set joint members for 50 percent movement each way. Adjust setting proportionately for installation at higher ambient temperatures.

C. Fastener Sizes: Use fasteners of sizes that penetrate substrate not less than recommended by fastener manufacturer to achieve maximum pull-out resistance.

D. Seal concealed joints with butyl sealant as required by roofing-specialty manufacturer.

E. Seal joints as required for weathertight construction. Place sealant to be completely concealed in joint. Do not install sealants at temperatures below 40 deg F (4 deg C).

F. Soldered Joints: Clean surfaces to be soldered, removing oils and foreign matter. Pre-tin edges of sheets to be soldered to a width of 1-1/2 inches (38 mm); however, reduce pre-tinning where pre-tinned surface would show in completed Work. Tin edges of uncoated copper sheets using solder for copper. Do not use torches for soldering. Heat surfaces to receive solder and flow solder into joint. Fill joint completely. Completely remove flux and spatter from exposed surfaces.

3.2 INSTALLATION OF COPING

A. Install cleats, anchor plates, and other anchoring and attachment accessories and devices with concealed fasteners.

B. Anchor copings with manufacturer's required devices, fasteners, and fastener spacing to meet performance requirements.

3.3 INSTALLATION OF ROOF-EDGE SPECIALITIES

A. Install cleats, cants, and other anchoring and attachment accessories and devices with concealed fasteners.

B. Anchor roof edgings with manufacturer's required devices, fasteners, and fastener

3.4 CLEANING AND PROTECTION

A. Clean exposed metal surfaces of substances that interfere with uniform oxidation and weathering.

B. Clean and neutralize flux materials. Clean off excess solder and sealants.

C. Remove temporary protective coverings and strippable films as roof specialties are installed.

SECTION 329000 SEEDING AND MULCHING

PART 1 - GENERAL

1.1 SUMMARY

A. This Section includes seeding, mulching, and fertilizing.

B. The areas to be seeded and mulched shall be all areas disturbed by contract operations, and as otherwise indicated.

1.2 SUBMITTALS

A. Product Data: For each type of product indicated.

B. Product certificates.

1.3 QUALITY ASSURANCE

A. Installer's Field Supervision: Require Installer to maintain an experienced full-time supervisor on Project site when planting is in progress.

1.4 DELIVERY, STORAGE, AND HANDLING

A. Seed, Fertilizer: Deliver, store, and handle materials according to manufacturer’s recommendations. Materials must be kept dry until ready to use.

1.5 METHOD OF MEASUREMENT

A. Seeding and Mulching is incidental to the project work unless otherwise specified.

PART 2 – PRODUCTS

2.1 PLANTING MATERIALS

A. Topsoil Source: Reuse surface soil on-site or import where not available on site. Topsoil source must be approved by COR.

B. Seed Mix:

1. To be approved by COR prior to placement

C. Mulches:

1. Straw Mulch: Provide air-dry, clean, mildew- and weed-free, threshed straw of wheat, rye, oats, or barley.

2. Straw mat netting for erosion control. Excelsior single sided straw mulch blanket with biodegradable netting as manufacturer by AEC Premier strawAE3000 or approved equal.

PART 3 – EXECUTION

3.1 PREPARATION

A. Finish Grading: Grade planting areas to a smooth, uniform surface plane with loose, uniformly fine texture. Grade to within plus or minus 1/2 inch of finish elevation.

B. Restore areas if eroded or otherwise disturbed after finish grading and before planting.

3.2 SEEDING

A. Sow seed at the rate of 15lb/acre. Apply Fertilizer at rate required by contract documents, if required by contract documents.

B. Rake seed lightly into top 1/8 inch of topsoil, roll lightly, and water with fine spray.

C. Protect seeded areas by spreading straw mulch. Spread uniformly at a minimum rate of 2 tons/acre to form a continuous blanket 1-1/2 inches in loose depth over seeded areas.

Spread by hand, blower, or other suitable equipment. Straw mat netting shall be installed according to manufacturer’s recommendations.

D. Hydro-seeding using the above seeding rates is also acceptable method of seeding.

E. Seeding shall be completed between April 1-June 1 for spring plantings and Sept.1- October 15 for fall planting.

F. Temporary seeding during winter months may be required and shall consist of winter wheat at 30lb/acre and straw mulch at one ton per acre.
