Rodgers Design Group's Services
1. Schematic Design Phase
Meet with Client to discuss the project’s requirements.
The Irrigation Designer will present similar typical Schematic Design drawings that illustrate the scale and relationship of the project components. It is during this stage that decisions regarding water requirements, potential water sources, power requirements, power locations and road crossings are developed. A typical sprinkler placement and coverage plan will be prepared after the initial meeting.
Client will furnish existing course base information from project engineer with ground control, topography and other required elements in hard copy and AutoCAD format.
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:
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:
3. Asset Identification of As-Is Golf Course Features & Irrigation Components
Most existing golf courses have less than satisfactory irrigation construction documents. The Irrigation Designer will utilize layer attributes then compile the data into a universal digital format, including separation for sprinklers, controllers, pipe sizes, valves, dimensions, road crossings, pseudo property lines and the golf course features.
During this phase a Global Positioning Survey showing all sprinklers, automatic valves, isolation valves, controller locations and present golf features will be collected. The format will include a latitude, longitude, and altitude of each reference points with a minimum reading every second for all line and area readings. All point type readings will take readings for a minimum of 5 seconds and will use equipment capable of recording accuracy of + or – three decimeters.
To insure all of the components are mapped the golf course staff will “mark/flag” all of the components to be mapped in the field with marking paint or wire irrigation flags. The components include sprinklers, automatic valves, splices, isolation valves, drain valves, wire routing (local utility locating firm to identify) controllers, air relief valves and any other irrigation component that is identified by the golf course staff. As the drawings are compiled, the golf course personnel will be responsible to assist with the identification of the sprinkler zone/controller combinations, review and comment on all pipe routings if existing drawings are available.
3b. Golf Course Labor and GPS Rental and Training for Asset Identification of As-Is Golf Course Features & Irrigation Components
There are many time when the end user would prefer to provide all of the labor to build their own as-constructed field conditions. The Irrigation Designer will bring a user friendly GPS unit to the site and develop a data dictionary specific to the site’s equipment and mapping needs. The cost is based on $1,500 for the first week and $1,000 for each following week. The field data will be processed in the Irrigation Design consultant’s office and returned to the client in a paper format at a scale of 1”=100’.
4. Prepare Geo Referenced Image
A satellite or other photo will be generated that is geo-referenced in a vector format which will
provide an actual image of the golf course in a layer under the GPS gathered information. The cost of this service is based on aerial image search, many times aerial imagery is available via Google maps, the Irrigation Designer will develop the images into the GPS geo referenced data.
5. Design Development Phase
Develop a Schematic Design drawing to further describe the Project’s size and character. Identify pumping facility requirements and distribution pipe routing and sizing, for hydraulic requirements of peak demand flow-rates.
Prepare a distribution hydraulic network analysis model identifying proposed distribution piping by node and pipe section. Input all data into hydraulic modeling analysis software for evaluation of proposed piping network in relation to projected peak flow requirements of each hole. Include pertinent data such as elevations, demand nodes, hydraulic grades and pressure regulating valve locations.
The Irrigation Designer will prepare detailed projection of course water requirements utilizing historical reference evapotranspiration data from closest weather station. We apply known turfgrass and landscape crop coefficients, estimated management factors, and anticipated irrigation system distribution uniformity to determine net monthly system water requirements. The Irrigation Designer will develop detailed monthly projections by each turfgrass type and list per month throughout the year indicating net application rate, monthly usage and total yearly requirement.
Generate detailed irrigation construction cost estimate including material and labor quantities and costs with estimated current market application of overhead and profit margins.
Following the meeting, The Irrigation Designer will develop a preliminary irrigation design in AutoCAD format at a scale of 1" = 100'. On this drawing, the following will be included:
6. Construction Documents Phase
Formalize the approved Preliminary Schematic Documents into Construction Documents that detail the Project’s construction requirements. The design documents will be prepared with details and specifications to insure that a well constructed, manageable irrigation system can be installed and will consist of the following:
It is anticipated that 2 design review meeting occur at the 60% and 95% design intervals for the Owner’s comments and approvals that the work to date includes all of the Project's requirements.
7. Construction Procurement Phase
Assist Owner to obtain a qualified contractor with valve-in-head/central control on large existing turf experience via a prequalification process. Upon creating a prequalified contractor list:
8. Staking and Construction Observation Phase
On-site staking is necessary to adapt the irrigation plan to the final configuration of the golf course in order to provide uniform spacing and proper coverage of all golf course features. Field adjustments shall be required for variations in the site conditions and construction changes that involve golf course features and limits of grassing.
Irrigation Designer shall review the material submittals to verify that they comply with the Plans and Specifications.
Irrigation Designer shall GPS field-locate and stake all sprinkler heads, isolation valves, air valves, satellite controllers, and mainline routing in coordination with the Irrigation Contractor. This will ensure accurate placement to provide uniform spacing and optimum coverage from the sprinklers.
Irrigation Designer will be required to GPS each golf hole to produce a final As-Staked Plan. The plan shall include all adjustments to the sprinkler layout, modification to the mainline routing and sizes as required, and satellite controller zone assignments. The As-Staked Plan
shall be used for installation of the system and provided to the installing Contractor and Owner in hard copy and PDF format.
Irrigation Designer shall inspect the finished product and note any items that do not meet the Plans and Specifications. A formal punch list document will be supplied to the installing Contractor and Owner. The
Irrigation Designer will verify that all items listed in the punch list document have been replaced / repaired and meet the Specification.
Irrigation Designer shall provide written reports to the Owner and the Irrigation Contractor after each site visit.
Upon the completion of the Project, the Irrigation Designer will be responsible for ensuring complete and proper irrigation coverage for the golf course. In addition:
The Irrigation Designer will participate in site visits of the Project as needed during the time construction is being done on the Project with the construction team to review the progress of construction and to see if the work completed is generally consistent with the intent of the Irrigation Designer’s construction documents. The Irrigation Designer will observe the construction methods of the Contractor to ensure proper installation of the irrigation components.
The Irrigation Designer will review required Contractor submittals, such as shop drawings and samples, but only to determine if they conform to the Irrigation Designer’s visual and aesthetic design intent.
The Irrigation Designer will review Contractor’s payment applications to determine if the amount of work represented as complete is generally consistent with the Irrigation Designer’s observations during its site visits. The Irrigation Designer’s review shall not be a representation that the Irrigation Designer has reviewed how or for what purpose Contractor has used or intends to use Owner’s payments.
9. Final Closeout
When the Contractor has finished installing the irrigation system and the computerized control system has been implemented by the Irrigation Designer who will perform a walk-through of the system with a representative of the Contractor and Owner. Notes will be collected and a punch list of items needing corrected will be presented in a report that the Owner will use for release of retention and will be the date defined as substantial completion. Items included for this service include:
After the Contractor has corrected the punch list items, the Irrigation Designer will return to the site and walk the site to assure the Owner that the irrigation system has been installed to the satisfaction of all parties.
10. Preparation of computer generated final construction record drawings
The Construction record drawings are the #1 tool that the Owner will use on a daily basis. This plan will show all vital irrigation equipment installed. It will be prepared from all of the field notes, staking data and site reports as generated throughout the Project. The plan will include the following:
The data will be prepared in a format that will provide a seamless transition from AutoCAD to Arcview. This data will be transferred by the Irrigation Designer to the unique central computer’s geo-spatial language.
11. Start-up of central computer and system optimization
Operational programming of the control system is necessary to achieve the most efficient use of the irrigation system. The computer based control systems that provide the flexibility for most efficient use of water and power must be programmed to operate the irrigation system as designed.
The services shall include the following:
12. Sprinkler yardage
One of the expected side benefits from having an automatic sprinkler system is having distances from the sprinklers to the green. Because of the technological tools we use every day, we are able to provide measurements for all par 4 & 5 golf holes from 90 to 250 yards out on all fairway sprinklers. In addition to measurements for each par 3 tee, the measurement will be to the front, middle or rear of each green. The Irrigation Design consultant will provide all measurements on a computer generated plan for record keeping.
