Seminar highlights: Tuesday 22 November

Civils 2005 22-24 November, Olympia, London Register at: www. civils. com Technical seminars have proved to be real crowd pullers at previous Civils exhibitions, and this year's crop promises to equal or even better past performance.

All visitors are welcome at the 50 minute seminars, which will be run in two purpose built theatres (red and blue) on the Gallery at Olympia. Entry is free and on a very informal basis - it is not necessary to book.

Visitors can attend as many seminars as they wish. During the three days of the show the 34 different presentations will run continuously from one hour after Olympia's doors open until about half an hour before closing.

This week NCE presents a brief précis of a fraction of the seminar programme - seminars for Civils days two and three will be featured next week. The full seminar programme will be featured on the Civils website - www. civils. com.

Red Theatre 11.30 Foundations for the 2012 Olympics - Roger Bullivant Director John Patch will take a rumbustious approach to the new construction needed to deliver the 2012 Olympics.

The vast majority of the build will occur on brownfield or poor quality sites, he says. The need for the construction of innovative, cost-effective, rapid, premier-quality, permanent and temporary foundations is immense. This seminar will seek to identify the challenges in the ground and the solutions available.

Blue Theatre 11.45 Weathering steel bridges - Corus Construction & Industrial Weathering steel is a high strength, low alloy steel that in suitable environments forms adherent protective rust 'patina', to inhibit further corrosion. Corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance.

Corus principal engineer Chris Dolling will give advice on a range of issues including design and detailing, fabrication, installation, inspection, maintenance and remedial measures - should corrosion rates exceed those anticipated at the design stage.

Blue Theatre 12.45 Restricted access secant piling - Van Elle Van Elle group managing director Richard Holmes will report on a challenging secant piled retaining wall constructed in extremely restricted conditions.

The wall facilitated deepening of a basement to accommodate a new art gallery in central London. Hard and soft 450mm diameter piles had to be installed in headroom of 3.5m - the hard piles being reinforced with 323mm diameter, thick-walled steel tube. Holmes' presentation will cover design, construction and testing of the works.

Red Theatre 14.30 Eurocodes and underground structures - Tony Gee & Partners When the Eurocodes were in their infancy they were first used between 1996 and 1999 for the contractor's design of a new metro. TGP principal engineer David Beadman will discuss the experience. He will highlight difficulties encountered and the benefits gained, with particular reference to the geotechnical design of the underground stations, using Eurocodes 1, 2 and 7. The observational method was adopted for the successful construction of one station, based on the requirements of Eurocode 7.

Red Theatre 15.30 Safe assembly of falsework and formwork - SGB The Work at Height Regulations 2005, introduced in April, place an increased responsibility on anyone involved in the selection of equipment for work at height to ensure that this can be carried out safely.

SGB's chief safety adviser Neil Murray and formwork product manager Stuart Bamford will explain the basis of the new regulations. They will show how SGB is helping to disseminate knowledge of safe assembly and dismantling throughout the industry with a state of the art, animated, series of user guides aimed at formwork and falsework product selectors.
