Demtech has worked in almost every state in the United States, Virgin Islands, Jamaica, Korea and Kazakhstan (former U. S. S.R.).

Many of our accomplishments include structures of record sizes or engineering feats! Which include: the only self supporting suspension bridge, the largest vertical lift bridge, the largest lock and dam on the Mississippi River, the longest over deck truss bridge, 11 million pound blast furnace and 300 Minuteman Nuclear Missile Silos.
