Hillsborough County Parks and Recreation Department (PRD) seeks qualified and certified Contractors to repair, maintain, and upgrade large-scale, computer-controlled commercial irrigation systems on over 170 parks and 250 sports fields with high-quality Bermuda grass with experience tracking wires and marking irrigation assets such as: controls, vacuum breakers, inground valve boxes, and irrigation clocks in a GPS (Global Positioning System) using a device with sub-meter accuracy. The services provided herein will ensure that all County parks and fields are properly irrigated, increasing aesthetic appearance and durability. Irrigation repairs shall include but not be limited to replacing missing or damaged heads, valves, wires, and micro-irrigation emitters; troubleshooting and designing hydraulics, wiring, controls, and computer/software system issues, retrofitting irrigation, underground boring, repairing leaking or broken pipes and tubing; adding or relocating heads in water-deficient areas; repairing updating and replacing computer controlled irrigation control clocks; replacing or rebuilding valves; and locating and repairing cut wires. See Attachment B and Attachment C for the County’s parks/facilities locations.

ITB-26-00127 Page 5

1.3.4 Plans or Drawings

The Contractor shall provide professional design drawings prior to the start of project.

The design drawings shall be clearly legible, to reasonable scale, show the entire site to be irrigated, including all improvements, and shall include but not be limited to: date, scale, revisions, legend, specifications which list all aspects of equipment and assembly thereof, water source, water meter and/or point of connection, backflow prevention devices, pump station size, pump station location, design operating pressure and flow rate per zone, precipitation rate per zone, locations of pipe, controllers, valves, sprinklers, sleeves, gate valves, etc. The plans and specifications shall be prepared in accordance with Section 106 of the Florida Building Code, Building.

1.3.5 Design Criteria

1.3.5.1 Irrigation systems shall be designed and installed to achieve the highest possible efficiency by providing operating pressures, sprinkler placement and nozzle selections that are within the manufacturers’ recommendations and maintained to keep the system at or within those ranges.

1.3.5.2 Water sources shall be adequate from the standpoint of volume, flow rate, pressure, and quality to meet the irrigation requirements of the areas to be irrigated along with other demands, if any, both at the time of system design and for the expected life of the system. Irrigation systems shall use the lowest quality water sources available on site. If the water source is effluent, it shall meet the advanced waste treatment standard set forth in Florida Statute §403.086(4), as well as any other standard set forth by federal, state, or local regulations or policies.

1.3.5.3 Sprinkler systems shall be designed to provide appropriate water uniformity for plant and soil types. Sprinkler head spacing, type, and nozzle selection shall be done to achieve the highest uniformity of application possible while avoiding watering various plant types as one group without regard for individual water requirements. The Contractor shall use application rates that avoid runoff and permit uniform water infiltration into the soil. Land slope, soil hydraulic properties, vegetative ground cover, prevailing winds and sun exposure will be considered when application rates are selected. Different types of sprinkler heads with different application rates (i.e. spray heads versus rotor heads, bubbler heads versus rotor heads, etc.) shall not be combined on the same zone or circuit.

1.3.5.4 Irrigation systems shall be divided into zones based on consideration for the following hydro-zoning practices:

1.3.5.4.1 Available flow rate, ITB-26-00127 Page 6

1.3.5.4.2 Cultural use of the area,

1.3.5.4.3 Type of vegetation irrigated,

1.3.5.4.5 Sun exposure,

1.3.5.4.6 Types of sprinklers employed (i.e. sprinklers with matching precipitation rates.

1.3.5.6 Pop-up spray head bodies in turf areas shall be no less than six inches (6”) in height for Saint Augustine, Zoysia and Bahia grass, and no less than four inches (4”) in height for Bermuda, Centipede and Seashore Paspalum grass.

1.3.5.7 Sprinklers should be located in all corners and on the perimeter of each irrigated zone area for a matched objective precipitation rate. Single row head spacing should only occur when an additional row will cause soil saturation at the toe of a slope or other inefficiencies.

1.3.5.8 No head shall exceed 50% of the manufacturers’ specified diameters of coverage. Water conservation will be emphasized by minimizing the irrigation of non-vegetated areas.

1.3.5.9 Micro irrigation systems should be designed using an emission uniformity concept, and micro irrigation emitters shall be spaced to wet one hundred percent (100%) of the root zone in turf areas and fifty percent (50%) of the root zone for shrubs and trees. Micro irrigation or low volume heads shall be required in all areas less than four (4) feet in either direction. All micro irrigation zones shall have adequate filtration installed at the zone valve or at the point where the drip tubing is attached to PVC popping to protect the emission devices from contamination from a PD main or lateral break. Each plant shall have an adequate number and size (GPH) of micro irrigation devices properly placed to meet plant water requirements in the event of no rainfall.

1.3.5.10 Pipelines will be sized to limit pressure variations to maintain a working pressure at all points in the irrigation system that allows for uniform water application. Velocities will be kept to five feet (5’) per second (1524mm per second).

ITB-26-00127 Page 7

1.3.5.15 The Contractor shall install manually operated control valves so they can be operated without wetting the operator. In-ground valves shall be installed away from large tree and palm root zones.

1.3.5.16 A manual shutoff valve shall be installed close to points of connection but downstream of any backflow device to minimize water loss when the system is shut off for repairs or in emergencies.

1.3.5.17 An automatic shutoff valve is required on all systems with a constantly pressurized mainline to confine the water loss from minor to mainline leaks, weeping valves, or stuck on valves to just the time system is operating automatically.

ITB-26-00127 Page 8

1.3.5.21 If an irrigation water supply is also used for human consumption, an air gap separation or an approved reduced pressure principal backflow prevention device is required.

1.3.5.22 The Contractor shall provide backflow prevention assemblies at all cross connections with all water supplies in accordance with County, municipal, and other applicable codes. In the event of conflicting codes/regulations, the Contractor shall provide the assembly type that gives the highest degree of protection.

1.3.5.23 Irrigation systems into which chemicals are injected shall conform to Florida state law (Florida Statutes 487.021 and 487.055) and Environmental Protection Agency Pesticide Regulation Notice 87-1, which requires backflow prevention regulations to be printed on the chemical label.

The equipment must also comply with ASSE 1013 to protect the water supply from back-siphonage and back-pressure. For other water supplies, Florida State law, EPA regulations, or other applicable local codes must be followed. In the absence of legal guidelines at least a PVB should be used.
