Abstract: After you’ve developed a drawing of your push-up green, you’ll need to plan the construction process to insure a successful project.
The push-up green construction project will include the following:
- Conversion of existing design grades to plan by total-station survey or other design processes.
- Field staking of work limits.
- Irrigation modifications/additions.
- Grade staking of green core.
- Green mix supply.
- Fine grading
Field staking begins by converting plan details to the work site. Define work limits by installing a survey stake every twenty feet, then connect the stakes with paint dashes. Expand area if field conditions show a water pocket or unacceptable land form.
Examine current irrigation routing and develop strategies to remove existing pipe and replace with new pipe. This usually involves cutting the pipe a few feet after a functioning valve. Don’t forget to mark the stub location with a stake painted orange.
Next mark out the green core, or the basin that will contain the green mix. I use 14″ depth. Install stakes every 10-20 feet as needed. Using golf green construction plans, transfer elevations from plan locations to green locations.
Using a laser and rod, mark out subgrade and finish grade elevations. This procedure requires advanced survey skills so call in professional help if needed.
Excavate core grades. Be careful to match the outside edge of the green core with the incoming edge of the surrounding surface. If the green grade , the surrounding area must correspond with a raised form that will provide a transition.
Install a few hundred feet of 4″ HDPE-double wall pipe installed in a herring-bone configuration in the bottom of the green.
Purchase new green mix or make it with on-site or locally available materials. Perform soil testing before committing to a suppler or blending process. Screen an extra 10% for installation overlap.
Install seedbed mix in the green core with an excavator or dozer. Compact with machine tracks to insure compaction and limit settling. Fine grade with a sand trap machine pulling a drag board, a heavy plank with a chain connected to each end. A central connection point insures that the board is dragged perpendicularly to the wheel marks.
