About this file

This is a standard details specification document prepared by the City of Tampa Parks and Recreation Department for irrigation system installations and repairs. The document provides comprehensive technical specifications and installation details for various irrigation components, including controllers, backflow prevention assemblies, valves, meters, and irrigation heads that will be utilized across multiple sites throughout the City of Tampa.

The specifications detail two primary controller options: an AC-powered 12-station Motorola IRRInet-M controller assembly (Model No. IMDC-12-RZ-S18P-AHT-SA-X) and a DC-powered 12-station Motorola IRRInet controller assembly (Model No. IMDC-12-RX-S18P-AHT-SA-X) with solar panel capability. Installation requirements include assembly, hot testing in-shop, radio programming, and optimization by the contractor, with final wire connections to be completed by Parks and Recreation irrigation staff. The document specifies detailed installation procedures for antenna placement, grounding rod installation using 5/8" x 8' copper rods, conduit routing, and component positioning relative to water sources. All components must be sourced from Central Control Systems, LTD (PO Box 8683, Woodland, CA 95776; Phone: 550-662-3776) with specific model numbers and hardware configurations prescribed throughout. Additional irrigation infrastructure details include pressure vacuum breaker and reduced pressure principle backflow prevention assemblies, master valves, control valves, flow meters, and various irrigation head types including rotor, pop-up spray, and bubbler configurations. The specifications require all work to be performed by the awardee with in-house services rather than subcontractors, with the exception of directional boring, which may be subcontracted if necessary.
