BRMCA Excellence in Customer Service Award 2018

A shortlist of three finalists for the BRMCA Excellence in Customer Service Award 2018 are:

Hanson for Royal Academy of Art Extension and Link Bridge

Key to the project's success was the use of self-compacting concrete (SCC) to achieve full compaction and high quality exposed concrete finish, whilst placing in narrow walls (150 mm) and in deep concrete lifts to minimise construction joints.  Hanson's technical department worked closely with specialist sub-contractor Getjar Ltd throughout the project to design a durable and reliable concrete, despite the restrictions imposed by the construction process.

Tarmac for Waterloo International Terminal, Wessex Capacity Alliance Suburban 10 Car 

Concrete required to achieve 20 MPa in eight hours using a blended cement with no more that 40% CEM I, where the same concrete had to remain live for two hours during delivery.  This was achieved using a high flow concrete, with an accelerating additive added to the concrete no more than just 20 minutes before the concrete was pumped 200 metres.  Final placing and compaction achieved without the use of poker vibrators.  Tarmac worked closely with the project team and the additive supplier to provide the concrete of the performance required.

CEMEX for Northern Line Extension

CEMEX supplied a demanding concrete for the cast in-situ secondary 250 mm thick lining to vaulted gallery sections.  Around 12 linear metres of tunnel were fully lined every 24 hours, establishing an outstanding performance rate in tunnelling construction.  This was only possible with the thorough understanding of the concrete design and performance, as well as the teamwork between the temporary works department and the on-site operators of the formwork system.

The award for the winning entry will be presenting at the Concrete Society Awards and Dinner on Wednesday 21 November 2018, at The Royal Lancaster Hotel, London.
