Complex floor at Freeport High School

Here’s the cast-in-place concrete floor being poured at the lower level of the Freeport High School addition. Workers are leveling the freshly placed concrete and performing various finishing activities.

What might seem like a simple floor system actually has many components that work together. The yellow material being covered in concrete is the under-slab vapor retarder that keeps moisture in the soil from entering the finished slab. A layer of extruded polystyrene insulation is hidden underneath the vapor retarder. Orange radiant heat tubes, attached to a layer of welded wire mesh and embedded in the concrete, will provide a comfortable and efficient source of heat for new rooms on the building’s perimeter.

Photographing the Capital Judicial Center #1

Beautiful September Saturday morning, early, walking out over the Kennebec on the pedestrian walkway of Augusta’s Memorial Bridge. The bridge isn’t vibrating nearly as scarily as it had during the scouting trips. There’s a barrier between us and the cars and trucks, which is good because they’re whizzing by only a few feet away. I’ve explained to Sandy, the photographer, and Justin, her assistant, that we don’t have to use a ladder to shoot over the chainlink fence, and we don’t have to shoot through the holes. We can just shoot under the fence.
