I just spoke with JT Grimes. Dam Safety is reviewing our plans. They have called for additional hydraulic modeling data on the emergency spillway. JT is working on this and will submit additional data to Dam Safety in a few days. He feels an approval will come after this new data has been submitted.
I have spoken this week with our engineer. He informed me that no one has been assigned to review our plans but he did call Dam Safety in Raleigh and request the best reviewer to review our plans. It is anyone’s guess as to when this process will be completed. Hopefully we will learn something within the next two weeks. Our project is formally out for bids and I will keep everyone informed as this plays out. If anyone has any questions on the project, I will try to answer them for you.
The engineer has completed the plans and specs. Everything has been submitted to Dam Safety on June 18, 2020. We expect a turnaround of the plans in 45-90 days. Any required revisions would be made immediately and resubmitted and out of review within two weeks. The engineer said we can begin the bid process with several contractors subject to any final revisions. It should take 3 to 4 weeks in the bid process. The construction start date based on this information could be late September to mid-November. The project is expected to take three (3) months barring major weather events. According to a contractor that we met, the lake will not have to be drained completely. A Cofferdam will leave about 10 feet of water in the lake. The fish and other aquatic life will remain in the lake. The Cofferdam will be constructed to control the water flow during slip lining.
Our engineer JT is running about 2 weeks behind due to Covid-19. He said he will be sending us all preliminary documents and reports for us to look over prior to sending to Dam Safety. Then if there is anything that needs tweaking or changing, we can do that prior to submitting. Once we hear back from Dam Safety with acceptance or changes, then we will get the finalized reports and documents with his seal and signature. We told him to start getting bids the day he forwards the preliminary reports and documents to us.
Before our February meeting, our engineer presented a preliminary plan to the board. He will have the finished plan with two options to submit to Dam Safety within the next 60-90 days. The reason he will be submitting 2 options for approval is to give us latitude to pick the less expensive option. We are hoping for a 60 to 90 day turnaround for approval of the plans from Dam Safety. During this time frame we will send out the finished approved plans for bid to contractors. Our engineer said that September, October and November are the best weather months for construction. Construction will take three to four months however he did say if pressed a contractor could conceivably get it done in 45 days.
According to our engineer JT, he expects to have conceptual drawings of the dam design by the end of January. He feels at that time we could also have an updated cost estimate provided by a contractor. By the end of February or beginning of March JT expects to have the completed drawings ready for approval by the Board. After we look over the plans and approve them, they will be submitted to the Dam Safety Board. JT is expecting a 90 – 120 day turnaround for approval. During this time JT will be posting our work for bids with various contractors. If all goes well, we are looking at possible construction by fall of this year. JT feels that fall will be the best time for construction for a project of our size.
