Today, while many features have been modernized, the hotel pays homage to the building’s past: The historic elevator remains; some of the original structure’s marble floors and wood-paneled walls have been preserved; and other details, for instance, the gable-crowned avant-corps and sand-lime brick façade, have been renovated to maintain the site’s historical grandeur.

In construction work silica is used in the form of stone, sand-lime brick, cement, mortar, concrete, etc.

This bond of hydrated calcium silicate is evidently different from, and of better type than, the filling of calcium carbonate produced in the mortar-brick, and the sand-lime brick is consequently much stronger than the ordinary mortar-brick, however the latter may be made.

The sand-lime brick is simple in manufacture, and with reasonable care is of constant quality.

Investigations and tests are being made, with a view to the preparation of working specifications for use in Government construction, of bricks, tile, sand-lime brick, paving brick, sewer pipe, roofing slates, flooring tiles, cable conduits, electric insulators, architectural terra cotta, fire-brick, and all shapes of refractories and other clay products, regarding which no satisfactory data for the preparation of specifications of working values now exist.
