Hired shot blastersaim up at reservoirDemolition at a lofty heightThe panoramic German restaurant on theDrachenfels, or Dragon’s Rock, above Königswinterin the Siebengebirge National Park onthe River Rhine is being replaced by a modernglass cube. The whole plateau at the summit isbeing conditioned to accommodate growth intourism. An Atlas Copco CombiCutter CC 2500U has managed to demolish the old restaurantunder difficult conditions.To begin with, the access road to therestaurant was iced over for weeks, making itimpossible to drive. Once the road was clear,the retaining wall along the road needed to bereinforced in parts to take the weight of the 25tCat 323 D excavator and the CombiCutter. Norubble was permitted to fall down the hillside andas a result, the outside walls needed to be takendown inwards towards the excavator.Time was also a pressure on foreman OlafGoldschmidt and his team from Dortmund-basedStricker GmbH & Co. KG. Demolition work had tobe completed by the end of February due to strictAs bid winner of the biggest refurbishment contractat the Mineirão Stadium, in Belo Horizonte,in the Brazilian state of Minas Gerais, contractorDetronic had the challenge of demolishing theentire bleachers area, where seats will be installed.The company used several Atlas Copco hydraulicbreakers for the project.The company’s civil works included thelowering of the field by 3.9 m, which requiredthe removal of 70,000m 2 of earth and thedemolition of electronic scoreboards and indoorstadium rooms.To handle the work the company developedrequirements regarding the protection of wildlife.Residents, visitors and the media alsoshowed great interest in the progress of demolitionwork. “I have never had so many curiousonlookers and representatives of the press on abuilding site,” says Olaf Goldschmidt. “The workattracted enormous interest.”The team managed to complete all demolitionwork in good time. Construction began on anew restaurant in May, 2011. Featuring a largeglass cube design, the building will also boast aspacious forecourt for visitors. The remodelledplateau will be officially opened at Easter 2012.The regional government will bear most of thecosts of about EUR 8million.www.atlascopco.comThe CombiCutter CC 2500Carrier weight class 22-35 tOperating weight 2,840 kgOil flow150-2,50 l /minOperating Pressure 350 barAtlas Copco breakersassist demolition in Brazila demolition plan, which involved the opening ofaccesses to allow entry of large equipment. “Weused the 140 kg hydraulic breakers SB 152,mounted on 8t mini-excavators,” says Detronicexecutive officer Ayres de Azevedo Barreto.“Only small equipment like those could move inthe limited area we had in the first stage of theconstruction.”After creating access for the larger equipment,Detronic started demolishing the bleachers usinglarger breakers, such as the SB 452, MB 750and HB 3100. The attachments were mountedon machines of up to 50t, demolishing 2,500m 3of concrete.The engineering plan devised by the companyprogrammed for the demolition of MineirãoStadium and the lowering of the field to becompleted in 150 days. “The high productivity ofA 300mm shot blaster removes coatings from the steel base of the reservoir.In Australia two self-propelled shot blasters,hired from Kennards Concrete Care, helpedwith the refurbishment of Canberra’s maindrinking water reservoir. The 415v, 250mmand 300mm shot blasters were used to removeoriginal coatings on the steel base of the 33million litre capacity tank before the 4400m 2area was recoated.ACG Industries, part of the Ausgroup ofcompanies, was contracted to undertake thework at Mt Stromlo Reservoir for ActewAGL,the multi-utility, which provides electricity,natural gas, water and wastewater servicesto the capital.This was the first refurbishment of thethe equipment involved allowed us to completethe works in less than 120 days,” says Barreto.“Considering the demolition tools available, thehydraulic breakers continue to be the mostrequested. They differ from the more specificreservoir in about 20 years. “Pot blasters arevery efficient, but they create so much dustyou can’t do anything else, such as priming,at the same time,” said ACT projects managerKerry Woodbridge. “The shot blasters produceminimal dust, which allows a full team to workalongside. We needed to achieve a surfaceprofile of between 40-70 microns. The roundedsteel shot did the heavy stuff, and removed thebulk of the coatings, and we then went over itwith a pot blaster. The recyclable nature of theshot is a bonus.”Kennards Concrete Care has hire centres inSydney, Brisbane Melbourne, Adelaide and Perth.www.concretecare.com.auattachments, such as pulverisers and demolitiontweezers. The first are the ideal choice for recyclingof rebar and concrete, whilst the latter are morefor demolition on sites of difficult access, as theyare heavier and require more robust machines.”48 PDi • Issue 2 • May - June 2011
Demolishing for newluxury hotel in BerlinIn the immediate vicinity of the Berlin Zoo Palast company UnitedHarvest Enterprises (situated in Abu Dhabi) invests on the Kantstrassein building a luxury hotel. This result in a filled up gap inthe capital of Germany.Meanwhile the dilapidated old buildings have become anuisance now and disappear piece by piece. By building a new118 m high hotel complex another grubby street corner is closed.Furthermore, there is a need for additional parking space, andthis done by creating a four-story parking garage underground.To realize this task, the pit reaches it final four-story deep withthe help of improvised floors. After the predetermined depth wasreached, they could start with the construction of the parking deck.Due to the design and load specifications the parking deck floorshad to be built in modular construction.The improvised floor was demolished and then to built thefinal ceiling of the parking decks. In this way, three improvisedtemporary floors had to be removed taking into account theirvery limited weight exposure.The company Kanellos GmbH of Berlin, that was in charge withthe demolition work, took the 40 cm thick and heavy reinforcedconcrete with 28 mm rebar away within a short time, by demolishingthe three floors with a total of 5.100m 2 heavy reinforcedconcrete slabs.The crushed material was recycled for re-use. For the demolitionof the heavily reinforced concrete ceiling demolition contractorKanellos had used a FRD concrete and steel shear type VC22FT.The product VC22FT out of the FRD full line a shear type with aservice weight of about 2300 kg, a jaw opening width of 895 mmand 530 mm long steel cutting blades could be used universally.The breaking of concrete structures became easy and cuttingthe rebar is clean and no additional time consuming dangerousgas cutting by hand is needed. Other FRD equipment that wasmounted on a mini-excavator was a hydraulic breaker FRD F3-LNfor trimming and cleaning out of the corners.The company Kanellos GmbH was able to continue theirprofessional work without using landfill space for most of thedemolished material.Wolfgang Gust plant manager was very pleased with theperformance of the FRD products. Attending area dealer companyReinhard Kienbaum was providing the fast and competent technicalservices and job site assistance. The completion of this new luxuryhotel is planned for late 2011.www.frd.eu“If cutting concrete,stone or masonryis your game...New 695 Series Utility Chain SawsWe’ve been using ICS chain saws for a long time.
