Book excerpt: Over £6 billion is scheduled for investment in the UK's railway infrastructure over the next few years, with £1.2 billion committed to enhancement projects, £1.3 billion to infrastructure maintenance and £1.2 billion on track renewals. Significant investment is also planned in signalling, telecommunications, electrification, stations and depot buildings. Bidding for, winning and completing this work requires an accurate knowledge of the costs, work and resources involved. Spon's Railways Construction Price Book provides that knowledge. Any company looking to participate in the regeneration of the UK's railway network, will find the guidance provided here an essential strategic asset. Compiled from years of specialist experience, this book provides an understanding of the key drivers and components that affect the cost of railway projects. The first edition rapidly became essential reading for designers, engineers, surveyors, project managers, contractors and all those involved in the railway industry. This improved and extended second edition is destined to take its place.
