2. Systems Analysis

The irrigation system is the most important and expensive maintenance tool a modern golf course will ever purchase. It needs to be maintained at a very high level in order to produce the turfgrass conditions as demanded by today's golfer. The modern day Golf Course Manager/Superintendent has so many duties that they are not physically able to monitor and repair all of the irrigation system components as needed and must trust members of the staff to keep the system in optimum condition. The Irrigation Designer is staffed with irrigation industry professionals and we see many items that will make the irrigation system work better on every project. During this phase a report will be generated that describes the system in general terms such as condition and life cycle expectancy of the many irrigation components. The Irrigation Designer will furnish a source for the Client to purchase the 24 hour pressure recorder directly from. Client will to use nightly to gather pressure data while the irrigation system operates. It will be the Golf Course's responsibility to move this measuring device around the course and return the data results to the Irrigation Designer for analysis.

This pressure graph will record 24 hours of pressure data and is an EKG type of monitor showing the results indicating the amount of stress the irrigation system is subject to. The Irrigation Designer will also take a copy of the current central computer data to be reviewed and included in the final analysis report.
Included in the report will be:
• Pressure recording findings
• Pump performance findings
• Central computer flow analysis
• Typical sprinkler performance graph
• Estimated water requirements
• Piping system analysis and comments
• Sprinkler zoning comments
• Life expectancy of the irrigation components
• Alternatives and preliminary costs

2b. Existing Plan Review

The irrigation system is one of the "hidden components" of a golf course, if the design and installation phases were performed correctly, the maintenance should be minimum. Unfortunately it is a line item component that is very expensive as to the proportion of the construction budget and subject to "Value Engineering" ideas that may affect the long term financial success of the project.

In the event a plan has been prepared by a firm whose primary interest is selling product the Irrigation Designer is available to provide a review service of the irrigation plan. A properly designed plan should include the following components:

• Typical sprinkler performance graph showing efficiencies of the proposed products
• Estimated water requirements in a daily and annual basis
• Piping system analysis and comments
• Sprinkler zoning/pairing comments
• Irrigation coverage of sprinklers should match the architects' most current grassing plan and provide separation of turf varieties
• Develop alternative delivery system for irrigation from the supply source to the reservoir, storage facility or directly to the irrigation system.
• Mainline system routing should provide flows to determine friction and velocities for operation set-up and design review of pressure losses.
• A written report describing the irrigation system design concepts and an estimated irrigation budget, with unit costs for the installed irrigation system components, the water supply system, and the pump system(s).
• A complete set of technical specifications and bid documents.
• The 120/240 volt electrical system should be easily identifiable.
• The communication cable routing should include routing to all field controllers, weather station, pump system for golf course and water supply source to golf course.
• Construction details for primary components should be provided to communicate intent of design and identify irrigation equipment assemblies.
• Prepare main pumping facility construction documents indicated pump station technical requirements, wet well and slab dimensions, intake flume sizing and routing and coordination between installation trades
• Head type and precipitation rate
• Turf type and crop coefficient
• Minimum cycle period per zone
• Maximum application duration per zone
• Identification of common groups
