PART 3 - EXECUTION

3.01 GENERAL

A. Before excavation, contact the "Underground Service Alert of Southern California" (USASC) for information on buried public utilities and pipelines. For on-site utilities retain an underground locating service.

B. Barricade trenches, ditches, pits, sumps, and similar Work outside the barricaded working area with chain link fence as specified in Section 01 5000 - Construction Facilities and Temporary Controls, and in accordance with Cal-OSHA standards and requirements.

C. Saw-cut concrete or bituminous paving for trench installation.

D. Trenches over 5 feet in depth shall conform to the Cal-OSHA.

E. Where indicated and required to excavate in lawn areas, protect adjoining lawn areas outside of the Work area. Replace or install removed sod upon completion of backfill by installing sod level with adjacent lawns. If installation of removed sod fails, furnish sod and install to match existing lawns.

F. Backfill over excavations to the required elevations with earth, gravel, sand, or concrete and compact as required. Provide excavations free from standing water by pumping, draining, or providing protection against water intrusion. Slope adjacent grades away from excavations to minimize entry of water.

G. Do not install piping lengthwise under concrete walks without review by the Architect.

H. Prior to placing the pipes, the pipe trench subgrade should be observed by a representative of the project geotechnical engineer.

I. Do not excavate trenches parallel to footings closer than 18 inches from the face of the footing or below a plane having a downward slope of two horizontal to one vertical, from a line 9 inches above bottom of footings.

1. Unless otherwise indicated on Drawings, depth of excavations outside the buildings shall allow for a minimum coverage above top of pipe, tank, or conduit measured from the lowest adjoining finished grade, as follows:

and as required for proper pitch and traffic load. (Install polypropylene sewer pipe with at least 24 inches coverage)

Irrigation Pipe: nonpressure pipe 12 inches, pressure pipe 24 inches

2. Trench width shall provide ample space for fitting and joining. Excavate for piping bells and fittings, bell and spigot pipe and other fittings.

J. Unless indicated otherwise, excavate trenches to the required depths for utilities, such as pipes, conduit and tanks, with minimum allowances of 6 inches at the bottom and 6 inches at the sides for bedding of unprotected piping or as required for concrete encasement of conduits as indicated on Drawings. Grade bottom of trenches to a uniform smooth surface. Remove loose soil from the excavation before installing sand bedding or concrete encasement.

K. Bedding must be placed uniformly on each side of the pipe and mechanically compacted. Flooding or jetting to densify the bedding materials is not allowed due to the clayey nature of onsite soils.

L. Provide excavations free from standing water by pumping, draining, or providing protection against water intrusion. If soil becomes soft, soggy, or saturated, excavate to firm undisturbed soil and fill as required. Slope adjacent grades away from excavations to minimize entry of water.

M. Provide a minimum clear dimension of 2 inches from sides of wall excavation to outer surfaces of buried pipes or conduits installed in the same trench or outside surfaces of containers and tanks.

N. Do not install backfill until required inspections and testing is completed.

O. Backfill electrical or other excavated utility trenches located outside of barricaded installation areas within 24 hours after inspection by the Project Inspector.

P. Install fill in loose lifts not to exceed 8 inches, moisture-conditioned within optimum and 2 percent above optimum moisture content, and mechanically compacted to at least 90 percent relative compaction in accordance with ASTM D1557. Thinner lifts may be necessary to achieve the recommended level of compaction of the backfill due to equipment limitations.

Q. If materials excavated from the Project site are not permitted for trench backfill in paved areas, backfill trenches with a cement-sand slurry mix. Install backfill to an elevation of the existing undisturbed grade plus one inch.

R. Install and compact sand bedding to provide a uniform full length bearing under piping and conduits.

A. Application of Soil Sterilant: 1. Mixing: Mix Soil Sterilant product in sprayer tank with clean water, according to

Manufacturer’s current printed instructions. Use sprayer, which will apply the solution uniformly, without disturbing the soil.

2. Spray Solution: Shake or stir prior to each application. Apply to dry soil surface only. 3. Application: Provide Soil Sterilant only in locations designated to receive Stabilized

Decomposed Granite Paving, as indicated on the Contract Drawings. 4. Over-spraying: Avoid spraying on walls, adjoining pavements, and all areas to receive

landscapee planting. 5. Depth: Immediately after application of spray solution, thoroughly incorporate the

solution into the soil to a depth of two-inches (2”) to four-inches (4”), per Manufacturer’s current printed instructions.

B. Compaction: After completion of soil sterilization operations, compact sub-base to minimum 90% compaction, or as recommended by the Geotechnical Engineer.

3.3 INSTALLATION

A. Installing Edging/Headers: Install Edgings/Headers, as indicated on the Contract Drawings. Refer to Section 32 94 00 – Landscape Planting Accessories for requirements. Edgings/Headers at the full depth of the perimeter of the Decomposed Granite, as indicated. Edgings/Headers shall be straight or curving as required, and securely in place, true to line and grade as required. Align header edges and set flush with adjacent paving where applicable.

B. Installing Geo-textile Filter Fabric: Geo-textile Filter Fabric shall be installed only in locations designated to receive Stabilized Decomposed Granite Paving. Install Fabric accordingly as indicated in the Contract Drawings to prevent weeds from growing up through the Stabilized Decomposed Granite Paving. Place the Geotextile Filter Fabric across the entire width of the Paving surface; overlap ends of Fabric rolls at a minimum of six inches (6").

C. Installing Aggregate Sub-Base (as applicable): 1. Verification: Do not place Aggregate Sub-Base prior to acceptance of sub grade

preparation. 2. Placement: Spread Aggregate Sub-Base to thicknesses shown on the Contract Drawings

and compact to a minimum of ninety-percent (90%) compaction, or as recommended by the Geotechnical Engineer.

D. Installing Stabilized Decomposed Granite Paving: 1. Verification: Verify locations to receive Stabilized Decomposed Granite Paving. 2. Lines and Levels:

a. Install Stabilized Decomposed Granite Paving true to grade, properly coinciding with adjacent Work and elevations.

b. Provide a finished Stabilized Decomposed Granite Paving surface uniform in texture and appearance. Do not permit finished Work to vary more than 1/8 inch in 10 feet from true profile and cross section. Finished Work shall be installed to fully comply as a universally-accessible pavement surface, per applicable Code requirements.

3. Mixing: a. General: Stabilized Decomposed Granite Paving shall be thoroughly pre-blended

before placement. b. Organic Binder: Thoroughly pre-blend Decomposed Granite material with

Organic Binder at the rate recommended by the Organic Binder manufacturer for each type of Decomposed Granite material specified, but not less than of twelve (12) pounds of Organic Binder per one (1) ton of Decomposed Granite material (dry weight). 1) It is essential the Organic Binder be thoroughly mixed, blended, and

uniformly incorporated throughout the Decomposed Granite material to achieve a successful result. The Organic Binder locks the fines in the Decomposed Granite material together, trapping the larger crushed aggregate screenings. The Organic Binder does not act directly on larger aggregate screenings. Proper mixing is a must for a successful application. a) Blending is best accomplished in a plug mill; a truck mounted mixer

or a portable mechanical mixer may also be used. b) Blend Stabilized Decomposed Granite Paving mixture for a minimum

of 15 minutes prior to placing on compacted sub-surface material. c) Drop spreading of Organic Binder over graded Decomposed Granite

material is not acceptable. Mixing by roto-tilling is also not acceptable.

d) Organic Binder shall not be applied during, just prior to, or immediately following rainfall.

4. Placement: a. General: After pre-blending, place the Stabilized Decomposed Granite Paving

material onto the compacted sub-surface material. Carefully place to avoid segregation in two (2) equal two-inch (2”) lifts.

b. Grade, screed, and smooth the Stabilized Decomposed Granite Paving to desired finish grades. Allow for compaction of the material.

5. Watering: Apply water until moisture penetrates to the full depth of the Stabilized Decomposed Granite Paving. a. Water activates the Organic Binder; it is essential that the full depth of the

Stabilized Decomposed Granite Paving is saturated at this time. Apply water from a hand held hose with a spray nozzle set to coarse spray. Water pressure should not disturb the leveled Paving surface. Do not use a water truck for water distribution or a high-pressure sprayer. 1) Test for water penetration through random core inspections. After

inspection of cores, fill cored holes with Paving removed; smooth and hand tamp to match adjoining surface grades.

2) A one (1)-hour application at a rate of +/-20 GPM per 1,000 sq. ft. of surface seems to achieve the desired full depth moisture penetration.

3) Let watered Stabilized Decomposed Granite Paving stand between six (6) to twenty-four (24) hours until all surface water has dissipated; the Paving surface should be moist, but not wet.

187

REF DRAFT - N

OT FOR CONSTRUCTIO

6. Compacting: While the Stabilized Decomposed Granite Paving material is still thoroughly moist, compact to a minimum 90% relative compaction, or as recommended by the Geotechnical Engineer. Compact each area with at least four (4) passes of the compacting equipment. After compacting, screed smooth. a. Compaction should be done with a heavy lawn roller (minimum 225 pounds and

maximum 30-inch width) to achieve finish grade and initial compaction. Hand-tamp edges around benches, signposts, trash receptacles, etc. Use a heavy (1-ton minimum) small rider, after having used the lawn roller, to obtain the desired final dense, smooth uniform texture. Do not use whackers, vibratory rollers or a vibrating plate tamper; the Stabilized Decomposed Granite Paving will not harden for weeks after vibration. 1) If the Decomposed Granite Paving surface is flaky or sticks to the roller

drum, the Paving hydration level is deficient; cautiously add more water as required to achieve the Paving’s proper hydration level.

2) If the roller creates a wash board effect or rills, additional time is required to allow the Paving to achieve the proper hydration level.

7. Contaminated Areas: Do not permit Stabilized Decomposed Granite Paving to contaminate adjoining planting areas or finishes. Clean up and remove all material spilled into adjacent planting areas.

8. Grading: When surface areas have been rolled and it becomes necessary to add a thin layer of Stabilized Decomposed Granite Paving material to bring the surface to grade, the previously rolled or compacted area shall be thoroughly scarified to a depth of two-inches (2”) to provide a bond with the added Material.

9. Curing: Allow finished Stabilized Decomposed Granite Paving surface to dry completely. Set-up time varies, depending on weather conditions. a. A hot, dry climate will set up sooner than a cool, moist climate.

E. Installing Decomposed Granite (Landscape Mulch Areas): 1. Verification: Verify locations to receive Decomposed Granite (Landscape Mulch areas). 2. Lines and Levels:

a. Install Decomposed Granite true to grade, properly coinciding with adjacent Work and elevations.

b. Provide a finished Decomposed Granite surface uniform in texture and appearance. 3. Mixing and Placement:

a. Mixing: Decomposed Granite shall be thoroughly blended with water before placement. Material should be slightly moist, granular, loose and dust-free.

b. Placement: Place the Decomposed Granite material onto the compacted sub-surface material, and after installation of irrigation pressure lines, boulders, cobbles, landscape planting, etc. Carefully place in an equal (minimum) two-inch (2”) lift.

c. Avoid placing Decomposed Granite material directly at the base of the landscape plant materials. Should any Decomposed Granite material settle into the growing meristems of the planting, carefully remove material without injury to the plant material.

d. Place Decomposed Granite at specified depth into any voids between cobbles, boulders, etc., as needed.

e. Grade, screed, and smooth the Decomposed Granite to desired finish grades, free from rills or rake marks. Allow for nominal compaction of the material.

4. Watering: Apply water until moisture penetrates to the full depth of the Decomposed Granite to further settle the fines, clean off plant materials, cobbles, boulders, etc., and to eliminate surface dust which may have accumulated during installation.

a. Apply water from a hand held hose with a spray nozzle set to coarse spray. Water pressure should not disturb or erode the leveled finished surface. Do not use a water truck for water distribution or a high-pressure sprayer.

5. Compacting: While the Decomposed Granite Paving material is still thoroughly moist, compact as needed to settle.

6. Contaminated Areas: Do not permit Decomposed Granite to contaminate adjoining pavement areas or finishes. Clean up and remove all material as required.


A. Tests: For each lift of Stabilized Decomposed Granite Paving, provide written verification as to the degree of compaction by a certified testing laboratory. Re-compact failed areas until specified compaction is achieved.

B. Testing shall be the sole financial responsibility of the Contractor.

3.5 INSPECTION

A. Finished Decomposed Granite surfaces shall be smooth, uniform and solid, with no evidence of shipping or cracking. Dried, compacted material shall be firm through the entire depth, with no spongy areas. Loose material shall not be present on the surface initially. After the first year of use, a minor amount of loose material is expected on the surface of Stabilized Decomposed Granite Paving finishes.

B. Loose Decomposed Granite material on the surface or unconsolidated crushed aggregate screenings below the surface of Stabilized Decomposed Granite Paving finishes is evidence of improper bonding due to poor mixing or insufficient watering. Test the loose material for adequate Organic Binder by wetting, then tamping, and allowing it to dry. If the material still is unconsolidated, the Organic Binder did not get mixed adequately throughout the Stabilized Decomposed Granite Paving material. If the material now is solid, initial watering was insufficient. Cracking or sponginess is evidence of excessive Organic Binder in the mix.

C. Unconsolidated Paving areas shall be excavated and replaced accordingly with new Stabilized Decomposed Granite Paving material with a high proportion of fines meeting the grading requirements above, and pre-blended with Organic Binder per the procedures listed above. Patched areas shall be wetted thoroughly and rolled smooth. Patching shall be completed prior to any surface smoothing.

D. Smoothing of Stabilized Decomposed Granite Paving: Significant irregularities shall be smoothed out prior to final acceptance of Work. Smoothing shall be accomplished by rewetting/saturating rough areas thoroughly, and then rolling the material again with a heavy roller (1,000–1,500 lb. powered walk-behind roller, or small rider). Whackers are not recommended.

E. Tolerances of Stabilized Decomposed Granite Paving: 1. Depth: Final thickness of completed Stabilized Decomposed Granite Paving shall not

vary more than 1/4-inch from dimension indicated in the Contract Drawings. Measurements may be taken by means of test holes taken at random, finished surfaces.

189

REF DRAFT - N

OT FOR CONSTRUCTIO

Correct any variations in the thickness beyond the allowable ½ inch by repeating the procedures listed above.

F. Width: Final width of completed Stabilized Decomposed Granite Paving shall not vary more than ½ inch from typical dimension width as indicated. Measurements may be taken at random cross sections along the finished surface.

G. Where installed, no edges of the Geotextile Filter Fabric shall be exposed.

3.6 REPAIRS AND PROTECTION

A. Damage or Defective Installation: Remove and replace Stabilized Decomposed Granite Paving that is damaged or defective, or does not meet the requirements indicated herein this Section.

B. Replacement of Stabilized Decomposed Granite Paving: If compression tests of cored samples fail to meet the specified compressive strengths as recommended by the Manufacturer, immediately remove and replace the Stabilized Decomposed Granite Paving with material conforming to the Contract Specifications.

C. Protection: Protect Decomposed Granite finishes against traffic, injury, defacement or damage (by rain or other outside force during curing period) and subsequent construction operations until Substantial Completion. Exclude traffic from Stabilized Decomposed Granite Paving for a minimum of fourteen (14) days after placement. When construction traffic is permitted, it is the Contractor’s responsibility to maintain Stabilized Decomposed Granite Paving as clean and level as possible by removing surface stains, spillage of materials as they occur, and traffic markings/grooves, etc., and to repair any damaged caused by said construction traffic.

D. Maintain Decomposed Granite finishes free of stains, discoloration, dirt, and other foreign material until Final Acceptance of Work.



B. Protect Stabilized Decomposed Granite Paving from damage due to landscape operations, operations by other Contractors and trades, and trespassers. Maintain protection during installation and maintenance periods.

OT FOR CONSTRUCTIO

N



lapping the edges a minimum of 1’-0”. Gabion Walls or specified Geotextile Filter Fabrics shall not be placed until the sub-grade/foundation is completed, and the sub-grade/foundation surfaces have been inspected and approved by the Engineer.

3.3 ASSEMBLY AND PLACEMENT

A. Assembly: 1. Gabion Wall welded wire reinforcement baskets are supplied folded flat and packed in

bundles. The units are assembled individually by erecting the sides, ends, and internal diaphragms, ensuring that all panels are in the correct position and the tops and all sides are aligned. The four corners shall be connected first, followed by the internal diaphragms to the outside walls.

2. Where lacing wire is used, wrap the wire with tight alternating single and double half-hitches at intervals between four-inches (4”) and five-inches (5”).

3. Where spiral fasteners are used, provide one (1) tight loop through each 3” x 3” opening in the Gabion Wall welded wire reinforcement mesh.

4. Crimp ends to secure the lacing wires or spirals in place. 5. Use the same fastening procedures to install interior diaphragms where they are required.

a. Interior diaphragms will be required where any inside dimension exceeds three-feet (3’) for Gabion Wall baskets thicker than twelve-inches (12”).

b. Diaphragms shall be installed to assure that no open intervals are present that exceed three-feet (3’).

c. For Gabion Wall baskets twelve-inches (12”) or less, rectangular cells are allowed with dimensions no greater than three-feet (3’) in one direction and not to exceed six-feet (6’) in the perpendicular direction.

B. Placement: 1. Place the empty Gabion Wall baskets on the prepared and approved sub-grade/foundation

and interconnect the adjacent Gabion Wall baskets along the top, bottom, and vertical edges using lacing wire or spirals.

2. Wrap the wire with alternating single and double half-hitches at intervals between four-inches (4”) and six-inches (6”).

3. Where Spiral fasteners are used, first screw down the spiral fasteners at the connecting edges, and crimp the end of each spiral to secure it in place. Lacing may be used as needed to supplement the interconnection of the welded wire reinforcement, and the closing of lids.

4. Interconnect each layer of Gabion Walls to the underlying layer of Gabion Walls along the front, back, and sides. Stagger the vertical joints between the Gabion Walls of adjacent rows and layers by at least one-half of a basket cell length (i.e. running bond pattern).

3.4 FILLING OPERATION

A. General: After adjacent empty wire Gabion Wall baskets are set to line and grade and common sides are properly connected, place in straight-line tension to gain uniform alignment. Staking of the Gabion Wall baskets may be done to maintain the established proper alignment prior to the placement of the aggregate/rock. Place Geotextile Filter Fabric in locations as indicated on the Contract Drawings, or in locations as needed to deter sediment erosion into the Gabion Walls. No temporary stakes shall be placed through the Geotextile Filter Fabric. Pre-formed

213

REF DRAFT - N

N



stiffeners or connecting lacing wire shall be attached during the filling operation to preserve the strength and shape of the structure.

B. Cross Tie Wires: Internal-connecting cross-tie wires shall be placed in each unrestrained Gabion Wall basket cell greater than eighteen-inches (18”) in height, including Gabion Wall basket cells left temporarily unrestrained. Two (2) internal connecting wires shall be placed concurrently with aggregate/rock placement, at each twelve-inch (12”) interval of depth. Place cross-ties or stiffeners (lacing wire or preformed wire stiffeners) across the corners of the Gabion Wall baskets, (at twelve-inches (12”) from the corners) to provide diagonal bracing.

C. Aggregate/Rock Placement: Gabion Wall baskets shall be carefully filled with the approved aggregate/rock either by machine or hand methods, ensuring alignment, avoiding bulges, and providing a compact mass that minimizes voids. At no point in the filling process may aggregate/rock be mechanically-placed from a height of over 36” from machine to fill area. Machine-placement will require supplementing with handwork to ensure the desired results. The cells in any row shall be filled in horizontal stages so that the depth of the aggregate/rock being placed in any one (1) cell does not exceed the depth of aggregate/rock in any adjoining cell by more than twelve-inches (12”). Along the exposed faces, the outer layer of aggregate/rock shall be carefully placed and arranged by hand to ensure a neat, compact placement with a uniform appearance. 1. Fill shall be placed in horizontal layers not exceeding twelve inches (12”) in compacted

thickness for heavy compaction equipment. For zones where compaction is accomplished with hand equipment, fill shall be placed in horizontal layers not exceeding six-inches (6”) in un-compacted thickness. Only hand-operated equipment shall be allowed within three feet (3’) of the wall face.

2. Fill shall be compacted per the recommendation of the geotechnical engineer or to a minimum 95% of the maximum density, and within +3%/-3% of optimum moisture content, as determined in accordance with ASTM D698 (Standard Proctor Density), whichever is greater.

3. In the absence of Owner’s direction to employ more stringent compaction specifications, the compacted density of the fill shall be tested every 2,000 square feet per 12” lift. a. Testing methods, frequency and verification of material specifications and

compaction shall be the responsibility of the Owner. 4. Heavy and/or construction equipment not involved with the wall construction shall not

operate within ten-feet (10’) of the wall face until final pavement and/or curbing is in place near the wall, as applicable.

D. Topping: The last layer of aggregate/rock infill shall be uniformly leveled to the top edges of the Gabion Wall baskets. The welded wire reinforcement lids shall be placed over the aggregate/rock infill using only approved lid closing tools as necessary. The use of crowbars or other single-point leverage bars for lid closing is prohibited due to the potential for damage to the Gabion Wall baskets.

E. Securing Lids: The Gabion Wall basket lids shall be secured to the sides, ends and diaphragms with spiral binders or lacing wire wrapped with alternating single and double half-hitches in the mesh openings.

3.5 REPAIR, CLEANING, AND PROTECTION

PART 3 - EXECUTION

3.1 AGRONOMIC SOIL FERTILITY REPORT/RECOMMENDATION

A. Once rough grading has been accomplished, and prior to commencing Soil Preparation operations, (amendments, fertilizers, etc.), soil samples shall be taken from representative areas and below grade depths of the Project Site. Locations and depths to gather the representative soil samples shall be accomplished by the Contractor under the direction of the Landscape Architect. 1. Provide 6 Soil Samples.

B. Guidelines for Selecting the Soil Samples: 1. Select representative areas to sample. The area needs to be uniform in color, texture,

depth, and drainage with the same fertilizing program and type of use. Planting areas to receive lawns, flowerbeds, trees, cut areas, fill areas, etc. should be tested separately. An area containing multiple trees and shrubs can be grouped into one area if the planting is the same.

2. Depths and process of soil sampling: a. Sample as deep as the soil will be amended, generally six-inches (6”) deep for

groundcover/lawns, eighteen-inches (18”) deep for shrub areas, twenty-four-inches (24”) deep for small boxed trees, and three-feet (3’) to four-feet (4’) for large boxed trees.

b. Use a soil probe or soil auger to remove a core sample; otherwise, use a shovel to dig a hole to the desired depth. Sample the soil from the side of the excavated hole, scraping the side with a trowel. The tools used for digging shall be clean and not rusty. Avoid sampling when the soil is too wet.

3. In desired areas where multiple sub-samplings are taken from any one (1) area to create a combined sample, mix the sub-samples homogenously together in a clean plastic bucket prior to placing in the plastic bag.

4. Each Sample shall be sent directly to the laboratory in a separate, re-sealable, one (1)-gallon plastic bag. Provide a minimum of four (4) cups of soil within each respective sample to allow for adequate testing.

3.2 SOIL PERCOLATION TESTING

A. Type/Quantity: During operations of Agronomic Soil Fertility Testing and prior to installing Plant Material, Contractor shall perform Soil Percolation Tests, through the direction of the Landscape Architect, in selected representative areas of the Project Site, to verify acceptable natural drainage, soil structure, and soil composition. Contractor shall verify the locations of the Soil Percolation Tests with the Landscape Architect. 1. Required Number of Soil Percolation Tests: 6

B. Procedure: Each Soil Percolation Test shall be performed as follows: 1. Dig a hole: 2’-0” wide x 2’-0” long x 2’-0” deep. 2. Fill the hole with water to top and cover with plywood and barricade. Allow hole to

drain and fill again to top. 3. Make daily observations, noting the depth of water each day. 4. Report findings, in writing, to the Landscape Architect. Include the length of time the

water takes to drain completely from each hole, date of test, location, and other information, which may be useful in providing further recommendations.

C. Results: Based on the combined results of the Agronomic Soil Fertility Testing and the Soil Percolation Tests, Contractor may be required to install additional tree drainage sumps or other drainage methods at each planting pit for trees larger than 15-gallon container stock. This does not relieve the Contractor’s obligation within the Base Bid to provide the required Tree Root Aeration Units indicated in Section 32 94 00 – Landscape Planting Accessories. Contractor shall include, as a line-item price within the Base Bid, the price per each additional tree drainage sump, should they be required (based on the testing). Should additional tree drainage sumps or other methods is required, compensation shall be awarded to the Contractor at the line-item price (each) as provided by the Contractor.

3.3 SOIL MOISTURE CONTENT

A. General: Do not work soil when moisture content is so great that excessive compaction occurs, or when it is so dry that dust will form in air, or that clods will not break readily. Apply water, if necessary, to bring soil to an optimum moisture content for tilling and planting. Soil moisture level prior to planting shall be no less than 75% of field capacity. The determination of adequate soil moisture for planting shall be the judgment of the Landscape Architect. Range: Maintain within two-percent (2%) above or below optimum moisture content at times during Work.

the soil surface. 2. Fertilize areas to receive planting with a 46-0-0 NPK commercial fertilizer at the rate of

½ lb. per 1,000 square feet. 3. After fertilization, irrigate the soil thoroughly and continuously at the equivalent of four

inches (4”) of water distributed over a fourteen (14)-day period. The application of water shall be applied to the soil as needed to gradually soak through the soil profile and not allowed to run-off the surface. Employ a specific watering duration and frequency program designed to germinate residual weeds. a. Providing full irrigation coverage for the limits of the subject areas under this

requirement shall be the responsibility of the Contractor. Contractor shall utilize permanent irrigation system installed under other Sections of the Contract, where available. Should limited coverage or no permanent irrigation system is available, Contractor shall provide temporary irrigation, as required, to fully meet the requirements herein.

4. After sufficient weed germination is present, apply non-selective, post-emergent contact herbicide, in strict accordance to the Manufacturer’s directions. Refer to Section 329400 – Landscape Planting Accessories.

5. Protect and buffer surrounding properties, buildings, and vegetation from overspray, as required.

6. Allow for a sufficient time period to ensure that the weeds are dead and the herbicide has dissipated, per the Manufacturer’s recommendation.

7. Water planting areas thoroughly and continuously for a period of one (1) week after the application of the herbicide. Discontinue the watering process for one (1) day prior to the second application of the herbicide. Apply a second application of the herbicide. Avoid any irrigation for a minimum of four (4) days after the second application for effective weed kill.

8. After the second application and waiting period, water planting areas thoroughly and continuously for three (3) consecutive days to saturate upper layers of the soil prior to commencing planting operations.

9. Dead weeds shall be cleared and removed prior to planting. 10. Maintain a weed-free Project Site until final acceptance by the Owner, utilizing

E. Compaction and Final Grading: Contractor shall provide sod beds that will not “footprint. Lightly rake and roll soil with two-hundred (200) pound water-ballast roller (filled 1/3 – 1/2 full), and bring level firm to finish grade. Final rolling shall be at right angles to slopes to prevent erosion. Sub-soil finish grade shall be sufficiently below the final grade to allow for the thickness of the sod material. Where applicable, newly sodded areas shall blend and match with existing turf grass areas so as to produce a smooth, unified field of turf grass.

F. Application of Fertilizer: Apply the Pre-plant Starter Fertilizer evenly throughout the area to be sodded, at the prescribed application rate. Evenly distribute fertilizer by applying equal quantities in two (2) directions at right angles to each other.

G. Raking: After broadcasting starter fertilizer, lightly rake and smooth seed bed surface to 1/4 in. depth. Install sod immediately thereafter, provided the sod bed has remained in a friable condition.

H. Sodding Operations: 1. Lay sod to form a solid mass with tightly fitted butt joints, with “green-side up”. 2. Starter Strip: Lay first row of sod in a straight line, with subsequent rows parallel to and

tightly against each other. 3. Butt ends and sides of sod; do not stretch or overlap. Stagger sod strips or pads (in a

running-bond-type pattern) to offset joints in adjacent courses. 4. Avoid damage to sub-grade or sod during installation. 5. Tamp and roll lightly to ensure full contact with sub-grade, eliminate air pockets, and

form a smooth surface. Work sifted soil or fine sand into minor cracks between pieces of sod; remove excess to avoid smothering sod and adjacent grass.

6. Lay sod parallel to the lay of the sodded area. Lay sod across angle of slopes exceeding 3:1, beginning at the bottom of slope area.

7. Anchor sod on slopes exceeding 6:1 with wood stakes spaced at two (2) pegs per square yard. Provide not less than two (2) anchors per sod strip to prevent slippage.

8. Cutting: Use a sharp knife to cut sod to fit straight segments or curves (and apertures in "turfblock" paving). Trim sod in straight lines when planting beds are linear or parallel to the hardscape elements. Trim sod slabs in a smooth, continuous curve when sod edges are placed against curvilinear hardscape elements.

9. Mulch Ring at Sod in Turf Grass Areas: sod in clean diameter circles around the perimeter of trees planted in turf grass areas, as indicated on the Contract Drawings. The Mulch Ring circles shall have the tree trunk located in the middle of the circle. Provide Organic Wood Mulch in these areas, at the designated thickness specified herein this Section.

I. Initial Watering: Saturate sod with fine water spray within two (2) hours of planting. Do not lay entire amount of sod before beginning watering. Water in lightly, when a relatively large area of sod has been placed. 1. During first week, water daily to supplement rainfall as necessary to maintain moist soil

to a minimum depth of two-inches (2”) below the sod until sod has rooted. Repeat watering at regular intervals until sod has established itself.

2. Once established, decrease the watering frequency and increase the amount of water per application.

J. Protection on Site: Erect temporary barricades, warning signs & flags, as required. Protect the sodded areas against vehicular and pedestrian traffic until sodded areas have established growth to the satisfaction of the Owner or Landscape Architect.
