8 | OHCC LIVING | SEPTEMBER 2023 | LANAI PROJECT STATUS AUGUST 2023 Much progress has occurred since our community overwhelmingly voted in our survey in October of last year, with (84.73%) in favor of the open-air Lanai proposal put forth by the Lanai committee. A full set of drawings have been created. Soil core samples have been taken and evaluated. We have hired a General Contractor. We have received quotes from sub- contractors. We submitted a complete project package to the city for permitting on June 27. Many of you may have seen emails circulating around the community recently questioning the project. Also, if you attended or watched the July Master Board Meeting, you would have seen the BOD and Lanai Committee response. Greg Kusiak did an excellent job of presenting the current status, and answering the questions that were raised in the emails. I will use much of his presentation here and fill in some details. 1. What is the length of construction? Approximately six months from issuance of permit due to a four-month lead time for the steel building fabrication. During the four months of the steel building fabrication, we will demo the current Lanai slab, and construct the foundation for the new building. 2. What is the volume of excavation? Approximately 200 cubic yards, including all footings and the deck slab. 3. How will it be hauled away and to where? It will be hauled in dump trucks with a capacity of five to 10 yards each, requiring approximately 25 trips. It will be used in sculpturing the lake, dam and surrounding area. 4. What is the duration of the drilling phase? e drilling phase will be approximately one week, with the possibility of a second week if the borings are excessively wet. 5. Were any prefabricated materials purchased? No. We will contract with Empire Steel to fabricate the structure once permitting is completed. e building permit application is pending. 6. What protections will the pool have? From a structural standpoint, we spoke on 18 July to Arumugam "Alva" Alvappillai, PhD. He is a Registered Professional Geotechnical Engineer with over 30 years' experience and the Principal Engineer on the soils study submitted to OHCC HOA April 10, 2023, by American Geotechnical, Inc. "ere is no significant risk to the structure of the pool if appropriate and customary construction practices are followed." For user safety, the pool area will be fenced off from the construction area. 7. Is there professional project management? Yes. We have contracted with Black Diamond Services, Inc. as the General Contractor with oversight by the Lanai Technical Oversight Ad Hoc Committee and the General Manager. 8. Will the pool be closed? For how long? We are planning to have the pool continuously open, but it is possible it will be closed for one week during drilling and one week during erection of the steel. 9. Will the golf course be impacted? e golf course will remain open throughout the project. 10. Will Clubhouse parking be impacted? It is expected that staging the project will cause the closing of the golf cart parking area on the former flag court. 11. Could the lanai be built on a slab instead of footings? No. Even the old lanai structure — which held up nothing but sunshade cloth — had stucco columns sitting on underground footings. 12. Could aluminum be used to lessen the footings requirements? Aluminum does not have the strength to span these distances without extraordinary support and is much more expensive than steel. Some of the footings requirements are to prevent wind liing and would be necessary for aluminum and fabric as well. 13. What footings would be required for a fabric structure? e soil conditions are the same problem for any structure requiring footings. Footings would be smaller for a fabric structure but still a significant expense. For example; the small sail shades at the Clubhouse pickleball courts required eight foot deep footings. 14. e size of the building footprint has not changed from the December Town Hall presentation. However, it has been shied toward the chipping green a few feet to improve the overall layout. e old Lanai structure was 50' x 50' totaling 2500sq . e new Lanai will be 60' x 60' totaling 3600sq , plus a 8' deep x 20' wide serving area for an additional 160sq . e serving area will have refrigerator(s), BBQ, and sink. ere will be an A/V area with a large screen TV and audio system. is will provide availability for residents to use the area to watch sporting events, and have other casual gatherings, when the area is not being used for scheduled events. ere will be heaters and a ceiling fan to allow year round use. 15. Was solar considered? Solar was considered but was rejected at present to hold down the initial cost. It can, however, be installed in the future if desired. 16. How this option was selected: Various alternatives for the replacement of the old shade structure were discussed over a period of years. More recently, social clubs using the facilities and staff scheduling and servicing them were surveyed and interviewed. e committee narrowed down the alternatives, created a model for resident viewing and conducted a large survey. 17. Why was this option selected? It is a cost-effective way to optimize the desired features. It provides a clear interior space uninterrupted by support posts allowing much greater flexibility in use. It can be created in an architectural style compatible with our existing architecture. Ad Hoc Lanai Construction Oversight Committee
