OMNNI provided construction administration services for the reconstruction of the existing STH 29/CTH FF at-grade intersection to a diamond interchange including bridge construction, box culvert extensions, bottomless culvert construction, several MSE retaining walls, concrete pavement and HMA pavement. The work included new frontage road construction and the construction of four roundabouts. Extensive coordination was required due to utility construction that was concurring with first phase of roadway construction.
