Dr Devon Mothersille attends technical meetings on Eurocode 7 in Naples, Italy – Nov 2018

As the UK representative on the task group advising on the revision of Eurocode 7 – Anchors (TC 250/SC7/WG3/TG5), Dr Mothersille attended a series of meetings held over a period of two days at Villa Doria d’Angri in Naples, Italy. This beautiful and historic setting provided the ideal environment for extensive and detailed discussions covering a wide range of issues related to the second generation of Eurocode 7.

The meetings were very well attended with over 100 delegates from countries all over Europe.

Based on his own area of expertise, Dr Mothersille attended general sessions on anchors, on both days, and also actively participated in specially convened additional sessions aimed at tackling comments submitted by task group members on the redraft of EC7 – clause 8 (Anchors).

Dr Mothersille visits Bauer’s Global Gateway Development project in Abu Dhabi – October 2018

Following the successful delivery of the seminars in Dubai and Abu Dhabi, Dr Mothersille visited Bauer’s Global Gateway residential development construction site in Abu Dhabi.

The project involves an excavation supported by secant pile walls which are themselves stabilized by an anchored pile cap. Importantly all the anchors on the project (166No.) are removable SBMAs with working loads of 800kN and overall lengths of 18.5m. In order to demonstrate removability of the prestressing strand, the client’s representative was invited to witness the removal process.

Three lengths of prestressing strand were successfully removed using a monojack initially and then with an excavator paying due regard to safety during the whole operation.

Enjoy the images of from this site visit.
