The offices, the toilets
and locker rooms are finished and fitted with materials in harmony
with the high-class character of the building. The masonry-floor
construction consists of concrete reinforced with expanded metal, and
except where iron or other floor plates are used, or where tile or
special flooring is laid, the floor is covered with a hard cement
granolithic finish.
In the design of the interior arrangements, the value of a generous
supply of stairways was appreciated, in order that all parts of the
structure might be made readily accessible, especially in the boiler
house section. In the boiler house and machinery portion of the plant
the stairways, railings, and accessories are plainly but strongly
constructed. The main stairways are, however, of somewhat ornate
design, with marble and other trim work, and the railings of the main
gallery construction are likewise of ornate treatment. All exterior
doors and trim are of metal and all interior carpenter work is done
with Kalomein iron protection, so that the building, in its strictest
sense, will contain no combustible material.
[Sidenote: _Chimneys_]
The complete 12-unit power house will have six chimneys, spaced 108
feet apart on the longitudinal center line of the boiler room, each
chimney being 15 feet in inside diameter at the top, which is 225 feet
above the grate bars. Each will serve the twelve boilers included in
the section of which it is the center, these boilers having an
aggregate of 72,000 square feet of heating surface.
