Rankin Dismantling Ltd have carried out a number of major demolition projects using varying techniques from mechanical demolition using our own plant to more technical top down demolition using mini excavators and hand tools. Mechanical excavation using our large Komatsu plant is carried out by demolition trained CCDO plant operators using a selection of quick hitch attachments from varying sized shears for steel works to our large hammer attachments for concrete slabs and foundations. For top down demolition we have a specialist demolition engineer in house who calculates floor loadings and requirements for propping and support schemes, this allows us to get the biggest equipment on site to get the scheme carried out within the tightest of programme

Rankin Dismantling Ltd were contracted By EHA Group and AECOM to undertake the major demolition of three buildings in Blackfriars. There were a number of logisiticalobstacles, dealing with both TFL and Southwark to get pavement closures parking suspensions and the new cycle superhighway routed without causing delays. A combination of both mechanical and top down hand demolition have been used to carry out the works. A major pre-demolition strip outs was undertaken to segregate waste streams and then our 30 metrehigh reach was bought on to site to start the sequential demolition process, this was married to a pair of PC-210 excavators to process the material and then a PC-350 arrived to break through the slabs and to excavate the basement. All three buildings required a scaffold protection to be designed and then erected. Upon completion of the demolition, the remaining basements have had a steel structure propping scheme installed.

Rankin Dismantling Ltd were contracted by Whitbread PLC. to carry out the demolition and site clearance of this Royal Mail sorting depot. This concrete structure had been fire proofed using a chrysotilespray when originally built, this had to be removed prior to the demolition. With a large amount of plant on site this building was demolished in full within 4 weeks and the site left clean for the builder to follow on.
One of the major stumbling blocks was the discovery of a 9" high pressure water main that serviced around 2000 properties, after liaising with Anglian Water this was isolated to allow works to progress.
