Technical Co-ordination Modern buildings are highly serviced, with all sorts of cables, pipes, ducts, light fittings, structural members and so on. Current-day thinking is for architects and engineers to share a 3D computer model to which they all have access and contribute while the design is being put together.
By contrast the Emberton approach in the 1930s was for the architect's drawing office to draw pretty well everything themselves in detail! - even light bulbs and pipe/duct cross sections drawn to scale in pencil ready for the dyline copying machine. Joe himself regularly designed the light fittings for his buildings. I suppose present day consultants may find this charming/amusing or perhaps actually impressive.
Central Service Core As far as I know, the Casino has never been used much for actual gaming. Most layout and footfall over the years has been from customers needing to be served and fed with a wide menu on offer and in good time.
The Casino has a circular plan, and at the centre were not just engineering services such as air conditioning but also staff, kitchens and serveries. So "back-of-house" is actually "middle-of-house."
This drawings shows structure, lighting, water supplies, heating pipes, air-conditioning and ventilation co-ordinated to run along the structural ribs emanating from the centre of the building in an integral kind of way. The ribs provided air supply and air extract in an alternating pattern.
