Also, the majority of the costs were spent in the UK. For example, the
construction industry was probably rather glad to have all the extra
work in an otherwise very lean period.

While I believe 98% of contracts in the Park were let to UK firms, that
does not mean the money stayed in the UK. First, many international use
UK subsidiaries, especially when bidding for public sector work.
Second, I live, and have lived, near the Olympic Park since well before
London's winning lie in 2005 and can assure you very many workers were
not from the UK and were taking or sending money abroad.

And the British architects of
the rather splendid venues can confidently expect more foreign
commissions (including designing the Rio Olympic park).

Possibly yes - for the few buyers who want a vanity project and don't
mind about budget and over-runs. But I suggest the much greater volumes
of bread-and-butter buyers will not be interested in, for example,
copying the aquatics cent see eg the comments from Sir Robin Wales.
I suspect the velodrome might do better - if they can sort out cheaply
the leaking roof.
