The Mina Plaza in Abu Dhabi comprised four towers covering a total built-up area of 246,000 sqm and 144 storeys. It was successfully demolished in a series of implosions at 0.25-second intervals over eight seconds.
Modon appointed Ramboll to provide the tender management and engineering supervision consultancy services on-site before and during the demolition.
Ramboll's team of experts provided full-time site supervision through the entire duration of the preparation work. This involved façade removal, MEP strip out, blockwork and debris removal, and supervising the drilling of over 14,000 charging holes.
A radius of 1,100m from the podium centre was established as an exclusion zone before the implosion. To limit the risk of flying debris, each vertical element charged with explosives was wrapped using geotextile and wire mesh.
No one was permitted within the exclusion zone apart from the demolition experts.
Ramboll also undertook a detailed dilapidation survey of the existing buildings within a 500m radius for the site and prepared the services protection drawings for the below-ground services.
Although Ramboll was not the design engineer for this project, our structural team created an ETABS model of the existing building to generate the forces and reactions used by the implosion experts to assess where it was possible to create openings in the existing vertical elements. In addition, the site team undertook a series of detailed site surveys to assist in the design decisions made by the implosion expert.
The demolition of Mina Plaza was part of a comprehensive renovation plan to redevelop designated areas of the iconic Mina Zayed area to transform it into a new tourist, commercial and residential destination.
