The South Major Acquisition Buying Office (MABO), 40001 SR 9336, Homestead, FL 33034 is seeking to repair the irrigation system at De Soto National Memorial. Contractor shall provide all labor, supervision, material, tools, equipment, supplies, operational testing, transportation and incidentals necessary to upgrade the irrigation system at De Soto National Memorial located in Bradenton FL 34209, Manatee County. The timer/controller for the sprinkler system shall be replaced with a modern multi zone model and shall be wired to the new valves using existing wiring. Sprinkler heads shall be replaced with new, appropriate style heads and in some cases repositioned to improve efficiency. The new components shall reuse existing PVC piping wherever possible. Zone valves, associated components and housing shall be replaced if needed. Existing Conditions: The existing irrigation system has been repaired multiple times and needs rehabilitation. Some sprinkler heads are positioned in inappropriate spots while several are malfunctioning all together. There are two zones in the system, with 3 valves each, totaling 6 valves. Although most of the valves work, some do not shut off promptly, due to malfunctioning diaphragms or solenoids. One of the sets of 3 valves is located on the edge of a mangrove swamp and is routinely under brackish water. This is a commercial system with mostly 2¿ PVC pipes. There are between 14 and 22 sprinkler heads connected to each of the valves, with a total of approximately 100 known sprinkler heads. All new equipment shall be approved by the COR prior to purchase and installation. The water supply pump was replaced recently and is in good working order. See attached photos. A. Modern multi zone (minimum of 6 zones) programmable timer/controller (similar to Rain Bird ESP 12-LX Plus model). In addition, the timer shall be both compatible with a remote control system (similar to -Remote Control Technology - Sidekick FM model) and a sensor system that interrupts watering when a wet condition is detected. B. 6 valves (replaced) C. Approximately 100 new sprinkler heads with appropriate style and size D. PVC pipe ½¿ up to 2¿ and associated components. E. Protective pump house EXECUTION: A. Zones shall be isolated, and valves are to be replaced. B. Once all the valves in a zone are in good working order, all sprinkler heads shall be aimed for optimal coverage. C. Removal and repositioning of sprinkler heads from undesirable spots shall involve installing new PVC piping and necessary components. All pipe trenching shall be kept to a depth of four inches D. A diagram of sprinkler heads location shall be provided, in addition to an appropriate watering schedule. E. New timer shall be programmed with park personnel given appropriate operational training.
