Crossrail Presentation – Xdisp Tunnel Analysis as part of a BIM Solution

Pietra Bolgna, Arup recently presented at the ICE Underground Space Conference in London, explaining how the innovative use of GIS and analysis software (Xdisp) have been used to achieve savings in design (and construction).

Damage assessment of third party assets using Oasys Xdsip -  is a bit of a “niche” but critical in terms of project risk for Clients. Damage to third parties, or even just third parties unhappy with the treatment they receive from Clients and their designers, can jeopardise projects. Damage to third parties is not uncommon even in high profile projects, occasionally with catastrophic consequences, so every new project raises the standards and increases the scope for damage assessment – plus there is room for optimisation of assessment methods.

Technical paper written by Oasys and Newcastle University: Slope stability analysis - limit equilibrium or the finite element method?

Which methods should practitioners use to analyse slope stability and how do these different methods compare?

Carol Matthews, Geotechnical Developer for Oasys, and Zeena Farook, Oasys Application Engineer, have teamed up with Dr Peter Helm, Research Associate at Newcastle University, to compare the results of Limit Equilibrium (LE) analysis of various slopes with different Finite Element (FE) Analysis.

The paper shows some interesting conclusions, including a close correlation between the LE and FE method for simple slopes. However, for more complex geometries or slopes that require analysis of seepage, consolidation and other coupled hydrological and mechanical behavior, the FE method produces more accurate results.

These conclusions could be used to help designers choose the correct methods for designing slope analysis. Read the full article here.

Automatic Cost Saving on Crossrail

Xdisp was used to produce automated damage assessment reports for more than 1,000 buildings. This saved time, reduced opportunities for error and speeded up re-assessment following scheme changes. Read the full article here.
