Words fromthe IDE President“A Lack ofForesight”As part of the new National DemolitionTraining Group Demolition Managercourse, candidates visit the BuildingResearch Establishment headquarters.The purpose of the visit is to seewhat materials are being used in theenergy efficient houses of the future,how those houses might be demolished,and what the proposed demolitionwould cost at today’s prices.In terms of energy efficiency andenvironmental impact, the house designsare cutting edge. And yet theconstruction methods and materialsemployed, such as <strong>com</strong>posite panels,cassettes and foam insulations, meansthat demolition is costly and timeconsuming.These houses of the future maysave thousands of pounds in energycosts over the lifetime of the house,but when they are due for demolitionall of those energy saving costs willbe negated by the higher costs ofdemolition.At the moment, demolition of theseunquestionably innovative houseswould cost 10 times more than demolitionof a similar-sized, traditionallybuilt house. And the arisings from thatdemolition, such as the cassettes and<strong>com</strong>posites, are all destined for landfillrather than reuse.Steve Tomlin of Masco Walcott is apassionate advocate of recycling andreuse and he has ready customers forthe brick, stone, slate, timber and glassused in traditional British housingstock. But I doubt very much thathe would have such a ready marketfor <strong>com</strong>posite panels, roof and floorcassettes and polystyrene.Architects must realise that mosthouses must one day be demolishedand that their designs should, therefore,take into account demolitioncosts and techniques. As it standstoday, the houses of the future maywell meet the government’s environmentaland energy efficiency targets,but in doing so they will prevent thedemolition industry from realising itswaste minimisation goals.The motor industry has beenmade to consider the recycling of<strong>com</strong>ponents via the end of life vehicledirective. So is the time right to introducean end of life building directiveto ensure that recycling and wastemanagement is considered within thedesign process?John WoodwardPresident of the Institute ofDemolition EngineersYoung Swiss cutting specialistsvisit Hilti in LiechtensteinSwitzerland is one of the countries where thejob of cutting concrete is an official and authorisedprofession. The apprenticeship takes threeyears; the young people learn their job in theirdiamond service contracting <strong>com</strong>pany on jobsites, the practical training in the training centreof the Swiss association SVBS (www.svbs.ch)and the theoretical education at the professionalschool BWZ (www.bwzofingen.ch).Recently the apprentices of class BT08,who will finish their apprenticeship in June,visited the Hilti headquarters in Schaan, Liechtenstein.The visitation was exclusively for thediamond products.

Discussions in repair and testing,Doosan rises to sixth placeDoosan Infracore Construction Equipment, theglobal alliance of construction brands that includesDoosan, Bobcat and Doosan Moxy, has risento 6th place in a newly published global leagueof the world’s leading construction equipmentmanufacturers.Much of the growth at DICE has been overseenby new Chief Executive Officer, Anthony C Helsham,who was appointed in April 2010. “2010 was anexcellent year for DI CE with a turnover of US$5.232 billion, <strong>com</strong>pared to a 2009 figure of US$3.288 billion,” says Helsham. “Doosan was alsothe only <strong>com</strong>pany in the top six manufacturers toproduce 2010 sales figures that were larger thanthose recorded for 2008.
