Crossrail - Presenting Building Damage Assessments to English Heritage

Arup Associate Director, Deborah Lazarus, joined an awayday for English Heritage’s national planning and conservation team on 24 September to advise on damage assessment and monitoring along the Crossrail route.

Deborah, from Arup’s Advanced Technology & Research team, explained the damage assessment process used for the several hundred listed buildings affected – including the offices of news magazine Private Eye in Carlisle Street and the Grade 1 listed Brunel Shed at Paddington railway station – and the wealth of monitoring that is taking place. This assessment is incorporated in Oasys Xdisp and has simplified analysis for Crossrail Engineers.

She also described some of the key buildings around Tottenham Court Road, for which the event’s venue, Centre Point, provided an excellent vantage point.
Deborah presented the Building Damage methodology used in Xdisp and demonstrated how this, along with a stringent monitoring system, were used to assess risk:


Mitigation methods such as compensation grouting were also detailed.

The presentation was received well and has increased awareness of how risk was addressed for such a landmark project. It also demonstrates how the Building Damage Assessment feature incorporated into Oasys Xdisp can be used effectively to limit the risk of settlement caused by tunnelling and major excavation.
