Following removal of all the original wooden floors, steel girders are installed in the east and west wings to support steel panels that will be topped with poured concrete.
Concrete for the floor is piped through an open window into the third floor of the west wing of Alumni Hall.
With the original wood floor, stage and balcony now entirely removed, foundation work continues in the central section that once used as an auditorium, later a library, a theatre, and finally offices; in the background, new steel floor panels are visible in one of the wings.
If this view seems strange, it’s because the original floor has been removed and we’re standing in what used to be the basement, looking up at the front door.
With the original floor removed, we can look all the way from the basement to the rafters in the central section of Alumni Hall. This view shows the curved south wall of what used to be an auditorium and theatre. On the other side of the wall is Seymour Union.
As concrete is pumped onto the third floor of Alumni Hall, workers move the delivery hose over the steel mesh, while other workers smooth the floor.
Not quite Leighton’s “Athlete Wrestling With a Python,” but it’s close: Workers use steel hooks and skid plates to maneuver the concrete delivery hose while spreading the floor in the west wing of Alumni Hall.
A worker signals the delivery crew outside whenever the flow needs to stop or resume through the hoses used to pump concrete up to the third floor of Alumni Hall.
Things are looking down — and up — at Alumni Hall. Removal of all the plaster ceiling, and a photographer willing to crawl through the incredibly dusty rafters, allows a view down into the central auditorium.
