The USS Constitution goes in for 3 yrs of refit. Meridian Associates, Inc. was there in the beginning!

The Constitution—called “Old Ironsides” because cannon balls could not penetrate her tough oak sides—was one of the first of the original six frigates that made up the U.S. Navy. A 44-gun frigate built at the Edmond Hartt Shipyard, Boston, Massachusetts, in 1797. She has a displacement of 2,000 tons, and carried a crew of more than 450.

Meridian was contracted to conduct high definition scans of the gun and spar decks to generate plans of existing structural members for renovations. The deck of the Constitution is slated for replacement to achieve conditions that more closely resemble the original design intent. Modeled features were developed to establish a physical baseline for the manufacturing of replacement beams and construction to establish a new centerline base line of the ship. Detailed documentation of existing conditions and location of historic features and elements were taken.
