Roman House, Barbican, London


  • Conversion of office building into apartments.
  • Design, manufacture and installation of 125 tonnes of structural steel.
  • Design and construction of an additional storey to the existing 8-storey structure.


  • Restricted-access at Central London location.
  • Site access necessitated use of a Spierings mobile crane weighing 80 tonnes.
  • Slew restrictions on the crane due to Roman ruins adjacent to building, which required that parts of the steelwork had to be retro-fitted with a spider crane,
  • Spider crane had to be manoeuvred into place using the Spierings crane.
  • Over-sail rights, road closures, parking suspensions and pre-delivery bookings with TfL (Transport for London) and Metropolitan Police.
  • All steel erected with MEWPs (mobile elevated working platforms), which meant existing roofs had to be back-propped.
