Front 9 Greenside Bunker Renovation

The Front 9 greenside bunkers were recently renovated using the Better Billy Bunker method.  All 22 bunkers, making up 21,650 square feet, were renovated in 3 weeks by Forefront Construction.  The weather couldn't have been better for the project and the cooperation from the Members allowed the project to fly by without any major setbacks.  The following is a summary of the step-by-step process.

All of the old contaminated bunker sand was removed and dumped on-site.  Some of the sand was stored in the dump facility to be used at a later date.  The remaining sand was placed on holes #3, 4, and 5.  In front of the creek on #3 used to be a gravel road used predominately by the maintenance department.  Sand was placed on the road to allow the bermudagrass to grow over this area and eliminate the shortcut.  The remainder of the sand was placed on holes 4-5 in the rough where the ground conditions were hardpan.  The sand will be spread out evenly and then topsoil will be brought in and hydroseeded with a 4-way cool-season blend.

  
Drainage was then inspected and replaced as needed .

A 2" layer of gravel was then applied to the entire bunker.

The grates seen in the photo were 2" thick.  The crew would place these grates in an area to make sure they were at a 2" level and then pick them up and move to the next area.  Here is a picture of the leftside bunker on #9 with gravel.

The next step was the application of the Better Billy Bunker polymer.  A licensed spray applicator, solely for the BBB polymer, was brought in to perform this task.  There was a 3-man crew who performed the job.  Robert sprayed the bunkers while another crew member held the hose.  The third crew member would rake and smooth out any imperfections to the surface right before the polymer was applied.  The polymer was heated during the process with a diesel forced air heater that was placed right against the barrel being used.  Heating the polymer allows the product to be pumped out of the barrel and sprayed without interruptions from clogged lines.

 

The following picture shows the bunker on #9 with the right-half sprayed and the left-half not yet sprayed.

Here is the right-side bunker on #8 with the entire bunker sprayed.  Stakes were put up to deter golfers from walking on the freshly sprayed polymer.  The polymer was given a 24-hour period to dry before sand was applied.  Every bunker was also inspected to make sure that the polymer was thick enough and that there weren't any imperfections, such as a golf ball making an indention.  A few ball marks were spotted and these areas were resprayed.

Once the polymer was fully inspected, fresh sand was placed in the bunker.  The sand is 4" deep and consistent throughout the bunker.

The entire bunker was compacted numerous times.  Water would be applied and the sand would be compacted again to make sure the depth was consistent at 4".

Every bunker was then checked thoroughly to make sure the sand was at the proper depth.

Finally, here is the bunker after having been raked.

The process couldn't have gone any smoother.  As mentioned earlier, this is a testament to the construction crew and their professionalism and the patience and cooperation from the membership.  While the new bunkers will take a little time to get used to playing, we hope everyone is happy with the final results.  We look forward to continuing this project in 2016.
