Preservation crews have been inside the inner lighthouse, working to complete structural repairs using special steel plates to support the structure, Grand Haven City Manager Pat McGinnis said.
“Forty of these have been placed around the inside perimeter of the inner light to fortify the seam and guarantee permanent structural stability,” he said.
McGinnis said these plates have been welded around the inner seam of the lighthouse using a specialized welding method recommended by structural engineers, a civil engineer, the project manager and the contractor on the job.
McGinnis noted that the issues inside of the lighthouse were discovered when crews were sand blasting them.
“When the metal was blasted, the corrosion around the first seam was worse than expected,” he said. “Over the past three weeks, engineers, managers and contractors have been discussing alternatives to a solution that would allow for the final coating of the inside and outside of the structure.”
Once the repair work is completed, preservation crews can begin to work on the next part of the project. A final coat of primer can be added, and then a fresh coat of red paint.
Grand Haven Lighthouse Conservancy’s Marci Cisneros noted that the painting is dependent on good weather.
The hope for all involved in the project is to have the process move along fast enough to get everything done before the winter.
