The mainline has begun! The blog site is under going some maintenance too so I will post the pictures in the morning. Exciting stuff out here today. Concrete walls were poured at the pumphouse, boring has begun for the mainline. We aerified the 17th green and topdressed a few more greens. The third tee box project is off the ground and the sod and some of the cart path was removed to be hauled away. The walls have begun to be dismantled and hauled off site as well.
As far as the mainline install, LUI has begun with the 18th hole. It is a 6" line that dead ends at the green. Their goal is to get into a rhythm and the process should go pretty smooth. Jose Acosta is the Irrigation Superintendent and has got a great team of guys of to a positive start. The first step is to remove the sod, roll it up to be replaced later. Next the trench is dug carefully watching for the current irrigation to keep it together. They will fix any damage to our PVC system. While removing the soil, they use a small "triangle-shaped" screen to achieve the best bedding of fill around the pipe. The back fill is as follows; 1/2 inch minus for bed of pipe, 12-18" of 2 inch minus fill and finally 3" minus for topsoil. Before back filling, a saddle will be fused onto the pipe for all of the lateral valves. Once the valves, prv's, drains and communication are installed, back filling will commence, the sod replaced and a final clean up before moving on. Check out the picture bar in the morning for detailed photos of this process.
