11.30 Red Theatre Reinforcement in the 21st century - The latest developments and how their application at T5 and CTRL ensured best practice Alex Small, director, Celsa Steel Over the past few years fabricators have been developing different ways to deliver reinforcement packages.

There is a real need to increase off-site procurement and reduce consultant detailing. Both at Heathrow T5 and CTRL, the supply of reinforcement has reflected this change, showing the benefits of electronic data transfer, off-site prefabrication, fabricator detailing and just-in-time delivery, with significant time and cost savings on design, detailing and construction and improved health and safety.

12.30 Red Theatre Geophysics and asset management - bridging the gap Simon Brightwell, director, Aperio The seminar will explore the move from visual inspection to machinebased data collection for condition and inventory assessments on road and rail networks. Entire networks can now be covered in a single survey combining surface conditions and asset data with subsurface information from ground probing radar. New software offers engineers a 'virtual site visit', creating a picture of what lies above and below the ground.

12.45 Blue Theatre Screwpiling: Ways of combining old and new technology Peter Dunn, chairman, Screwfast Foundations The presentation will refer back to the original Victorian invention where manned capstans were used to install cast iron helices on wrought iron shafts to support many structures. The upsurge in screw anchors after the Second World War in USA, in Australia in the 1970s and recent research and advanced techniques developed by Screwfast Foundations will be covered. The firm is developing remote sensing systems to enable it to track and monitor pile installation around the world by its network of installers.

13.30 Red Theatre Health and safety competency - changing hearts and minds Kevin Fear, head of health, safety and environment, CITB Construction Skills Achieving and maintaining high levels of health and safety competency is a key goal of the construction industry. Ensuring these levels are reached, ultimately requires a behavioural and cultural shift towards improved health and safety by industry. This seminar will examine some of the steps being taken by different industry sectors to ensure competency is and remains an integral issue. The roles all individuals and organisations can play in achieving this will be highlighted, along with lessons that can be learnt from other industries.

14.30 Red Theatre Crossrail: From concept to reality Bernard Gambrill, head of public affairs, Crossrail Crossrail is a proposed main line railway system running east west in tunnels beneath central London. It is being promoted by Cross London Rail Links, a joint venture company owned by Transport for London and the Department for Transport. The railway will bring major benefits to the city and the UK, through faster journey times and greater accessibility. Gambrill will focus on congestion relief in light of London's predicted population growth.

15.30 Red Theatre Augered displacement piles for brownfield sites Ondrej Synac, principal geotechnical engineer, Pennine Vibropiling Augered displacement piles are finding increased use on brownfield and urban development sites and the development in recent years of more powerful rigs, together with precise installation monitoring techniques, has contributed to wider acceptance.

Testing in Europe and the UK indicates augered displacement piles' enhanced capacity and stiffness are closely linked with pile shape and installation technique.

Pennine's Penpile system combines the advantages of CFA and driven piling, providing a bearing pile that can be installed with minimal noise and vibration, virtually no spoil and reduced material cost. Case histories and design principles will be presented.

15.45 Blue Theatre Precast concrete retaining walls, T-walls and ground beams for use in construction Roy Spurgeon, UK sales and marketing manager, Bell & Webster Concrete This seminar will discuss how best to specify and use precast retaining walls, T-walls and precast concrete ground beams for construction. The manufacturing process will be described, plus case studies of various applications including earth retention, marinas, canals, materials storage, underground car parks and ground beams.
