SOLUTION

WJE played an integral role at every stage of the successful relocation effort. As part of the pre-move survey, WJE preservationists conducted laboratory analyses of the historic mortar to determine its material properties; documented existing distress and cracking; and compression tested core samples from the granite plinth and brick shaft to establish the strength of the existing materials.

From the thorough assessment, WJE engineers developed a computerized monitoring system to ensure the safe movement of the lighthouse. Fifty-six sensors installed in the structure measured tilt, vibration, acceleration, strain, and climate conditions, relaying data in real-time to the design-build team.

After twenty-three days of incremental movement, the lighthouse arrived at its new location, where WJE preservationists oversaw the construction of a new brick base and performed a post-move survey. Despite the arduous 2,900-foot move, no existing cracks increased, and no new cracks developed. As a final testament to WJE's meticulous efforts to preserve and strengthen the structure, the newly placed lighthouse weathered two hurricanes without damage just one month after relocation.
