ECI – Engineers Construction

ECI’s Ryegate Culvert Project  was recognized  by the Northern New England Concrete Promotion Association for “Cast-in-Place Concrete Structures” at the NNECPA Annual Meeting.  We were nominated by Carroll Concrete, an NNECPA member and ready-mix supplier of the concrete for the project.

The culvert project involved over 2,400 cy of concrete, designed for a 100 year service life.   The unique complexity was the 32-ft arch span formed and poured using a Doka form system.  The 2.5-ft-thick wingwalls reached a height of 27.5 feet above their footings and were accomplished in a single pour each.  Reinforcing steel was both uncoated and dual coating, depending upon its location.  The headwall and wingwalls were formed using a liner to provide a more aesthetic appearance.
