Construction
Sandwich Plate System (SPS)
By making use of SPS terraces, the Aquatics Centre has
now shifted effortlessly into legacy mode. The main building
will remain a competitive swimming arena, but with
only 5,000 seats on SPS terraces. The remaining 15,000
seats, together with their load-bearing steel-polyurethanesteel
structure, will be simply demounted and redeployed
elsewhere. This is a breakthrough in the history of stadium
construction.
Time, cost, efficiency and flexibility – powerful arguments
in favor of SPS terraces.
Stadium seating constructed from SPS terraces offer a
wealth of benefits previously unavailable in modern stadium
construction. The extremely strong and lightweight steelpolyurethane-steel
sandwich has everything going for it.
Polyurethane is the material that is not only more durable
than conventional construction materials, but utilized in SPS
plates allows grandstands to be up to 75 percent lighter
than those constructed with concrete. Prefabricated off-site,
SPS adapts seamlessly to any architectural constraints, thus
reducing construction time and costs considerably. It makes
no difference whether the stadium is new or undergoing
modernization to increase its seating capacity.
What goes up can also come down. And go up again.
The best way to create space today for the press, public
and new projects.
What’s now possible in London could soon become the
standard procedure in modern stadium construction. Nothing
has to stay the way it is forever. And, from now on, no
idea needs to be rejected on grounds of “alleged” expense.
SPS is a magnificent example of the incredible versatility of
polyurethane. It may not be feasible (yet) to move whole
stadiums, but moving whole stands already is. And, as if
The new Aquatics Centre has 20,000 seats of which 15,000 can be
simply demounted and set up again elsewhere. Easily achieved
using SPS.
