Salt Lake City School District 32 84 00-10 East HS Baseball Field

2. Because this project has significant topography that could require alteration of irrigation equipment layout as deemed necessary by Owner, do not install irrigation equipment in these areas until the Landscape Architect and/or Owner’s Representative has reviewed equipment staking.

3. Location of heads and piping shown on Drawings is approximate.

3.3 INSTALLATION

Salt Lake City School District 32 84 00-11 East HS Baseball Field

A. General: Plans are diagrammatic. Proceed with installation in accordance with the following:

1. Install stop and waste valve and other equipment required by local authorities according to Utah Laws and Regulations to make system complete.

2. Install main line, automatic control valves, lateral lines, fittings, and heads/drip line as specified.

3. Thoroughly flush main lines before installing automatic control valves, and laterals before installing sprinklers. Flush supply lines thoroughly before installing backflow preventers or other regulating devices.

B. Piping: Assemble all mainline and lateral lines in accordance with manufacturer’s recommendations.

1. Install PVC pipe in dry weather above 40 degrees F as specified by manufacturer's recommendations. Allow joints to cure a minimum of 8 hours before testing.

2. Snake pipe in trench as much as possible to allow for expansion and contraction. When pipe laying is not in progress, or at end of each day, close pipe ends with tight plug or cap. Perform work in accordance with good practices prevailing in irrigation industry.

1. Shield pipe from direct sunlight so that expansion and contraction do not affect the integrity of glued fittings. Temperature swings from daytime to night time can cause pipe to completely pull out of glued fittings. Consult with the manufacturer for proper shielding of PVC pipe before installation and provide the Owner with the proposed method for shielding the piping.

2. Ensure that mainline and lateral lines don’t conflict with utilities, fire hydrants, light poles, underground sumps or storm drain and downspout piping or other utilities. Refer to civil and electrical plans for locations of these utilities. Re-route mainline and lateral lines as necessary to avoid these and all other utilities.

3. Locate no sprinkler head closer than 6 inches from building foundation. Heads immediately adjacent to mow strips, walks, or curbs shall be one inch below top of mow strip, walk, or curb and have 4 inches clearance between head and mow strip, walk, or curb.

4. Insert a dielectric union wherever a copper-based metal (copper, brass, bronze) and an iron-based metal (iron, galvanized steel, stainless steel) are join

5. Cut plastic pipe square. Remove burrs at cut ends before installation so unobstructed flow will result.

6. Make solvent weld joints as follows:

a. Do not make solvent weld joints if ambient temperature is below 45 deg F.

b. Clean mating pipe and fitting with clean, dry cloth and apply one coat of P-70 primer to each.

Salt Lake City School District 32 84 00-12 East HS Baseball Field

PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine areas to receive sod or seed for compliance with requirements and other conditions affecting performance. Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 PREPARATION

A. Protect structures, utilities, sidewalks, pavements, and other facilities, trees, shrubs, and plantings from damage caused by planting operations.

B. Provide erosion-control measures to prevent erosion or displacement of soils and discharge of soil-bearing water runoff or airborne dust to adjacent properties and walkways.

3.3 SOD BED PREPARATION AND INSTALLATION

A. Limit subgrade preparation to areas to be planted. Install on site topsoil to a 4” depth. If imported planting soil or imported topsoil is required, ensure they meet the requirements of this section.

B. 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. Roll and rake, remove ridges, and fill depressions to

Salt Lake City School District 32 90 00-6 East HS Baseball Field meet finish grades. Limit fine grading to areas that can be planted in the immediate future.

1. The Installer shall prepare no more ground than can be sodded in a twenty-four (24) hour period. Sod shall be placed within 24 hours of ground preparation. The ground shall be re-prepared if weather or traffic has compromised the friability of the prepared area.

2. No sodding shall be done immediately after a rainstorm or if a prepared surface has been compacted without first loosening the surface to a smooth, loose, uniformly fine texture just prior to sodding.

C. Apply Biosol mix fertilizer at a rate of 33lbs. / 1000 SF. Apply fertilizer directly to fine grade. Remove stones larger than 1 inch in any dimension and sticks, roots, rubbish, and other extraneous matter and legally dispose of them off Owner's property.

1. Delay mixing fertilizer with planting soil if planting will not proceed within a few days.

D. Moisten prepared sod areas before planting if soil is dry. Water thoroughly and allow surface to dry before planting. Do not create muddy soil.

E. Areas where sod is to be laid shall be cut, trimmed, or shaped to receive full width sod (minimum 16”). No partial strips or pieces will be accepted.

F. On site lawn may be cut at a minimum 16” width with a one (1) and one quarter (1/4) inches soil profile. If this option is selected in lieu of importing sod rolls, cut lawn shall be re-laid within 72 hours of being cut, and shall be kept from drying out. Utilization of existing lawn does not release contractor from any other requirements within construction documents.

G. Place sod on prepared surface so that joints between courses are matched against the last line laid.

H. All work shall be done from boards laid on top of the prepared surface or on already laid sod or existing established lawn. Care shall be taken to prevent footprints or other disturbances to the prepared bed. Any such disturbances shall be promptly repaired so that the sod will be laid on a proper bed to ensure the necessary bonding between it and the sod.

I. Sod shall be tamped lightly as each piece is set to ensure that good contact is made between edges and also with the ground. Sod laid on any sloped areas shall be anchored with wooden dowels or other materials which are accepted by the sodding industry. Roll sod immediately after placing using a hand roller half filled with water.

B. Erect barricades and warning signs as required to protect newly planted areas from traffic. Maintain barricades throughout maintenance period and remove after lawn is established.

C. Remove erosion-control measures after grass establishment period.

D. Maintenance During Lawn Establishment:

1. General: Begin maintenance of the lawn areas immediately after each area is planted and continue until acceptable lawn is established. Maintenance shall include watering, fertilizing, eradicating weeds, mowing, trimming, protecting slopes from erosion, maintaining mulch material, protecting lawn areas from traffic, replanting and other operations. Roll, re-grade, and re-sod bare or eroded areas and re-mulch to provide a uniformly smooth lawn.

2. Repair: Lawn areas shall be re-established as specified herein for eroded, damaged or barren areas.

3. Mowing Installed Sod: Mow sodded areas as soon as top growth is tall enough to cut. Repeat mowing to maintain specified height without cutting more than 33 percent of grass height. Remove no more than 33 percent of grass-leaf growth in initial or subsequent mowings. Do not delay mowing until grass blades bend over and become matted. Do not mow when the grass is wet. Schedule initial and subsequent mowings to maintain the following grass height:

a. Mow grass 3 inches high.

4. Watering: Provide and maintain permanent irrigation system to convey water from sources and to keep lawn uniformly moist to a depth of 4 inches.

a. Schedule watering to prevent wilting, puddling, erosion, and displacement of mulch.

b. Water lawn at a minimum rate of 1 inch per week through establishment period.

5. Lawn Post Fertilization: Apply fertilizer immediately after installation initial mowing and when grass is dry. Water after application.

a. Use a commercial fertilizer 20-20-20+ iron that will provide actual nitrogen of at least 1 lb./1000 sq. ft. to lawn area at a total rate of 5 lbs./1000 sq. ft.. Apply no more than 1 lb./1000

sq. ft. for each application.
