Work continues on Iowa State's $84 million Student Innovation Center on the west side of campus. (Top) Earlier this week, a crew was pouring concrete for the second floor. Framing the construction site is Sweeney Hall to north and to the west, Bissell Road, torn up in sections this summer for multiple utility projects. (Below) Crew members used a variety of methods -- from a long 2x4 on a rope to a hovercraft-like riding trowel -- to smooth the floor surface.
