BACKGROUND As a continuation of course renovation work that started last year, on February 21, 2017, Council awarded a not-to-exceed $140,000 contract to D.H.R Construction Inc. for the renovation of bunkers on holes #3, #8, and #9 to keep up with the Callippe Preserve Golf Course multi-year bunker improvement plan. DISCUSSION During moderate rain events, sand erodes from the bunker faces exposing dirt and rock which washes into the existing bunker sand, thus leading to poor drainage and consequently limited playability. Due to this contamination, the bunkers no longer drain effectively and are difficult to maintain. In order to achieve a successful project, D.H.R Construction Inc. utilized the Better Billy Bunker Method to renovate the six bunkers located on holes #3, #8 and #9. Once the contaminated sand is removed from the bunker the interior drainage system is inspected for improvement or replacement. After the drainage system has been cleaned or replaced, a two inch layer of gravel is installed. The gravel is then sprayed with a ST410 polymer that binds the gravel to prevent future sand contamination from erosion. Once the polymer has cured, a four inch layer of bunker sand is installed. All of the work has been completed to the satisfaction of the Director of Operations Services and it is recommended that the project be accepted as complete. Budget The final contract cost is $133,202.20 from the original allocated funding of$140,000. Staff recommends the project balance of$6,797.80 be transferred to the FY 2017/18 Golf Course Repair and Replacement Budget. The final project funding and expenditures are summarized in Attachment 1 to this report. Su•mitte•.
