We are proud to once again be working with BAM who will transform an underutilised industrial estate sitting on a 1.2 acre self-contained ‘island’ block near St Pancras Hospital, with a main office building and two separate blocks of flats. The scheme has been designed by architects Caruso St John.
Three heavy-duty luffing jib tower cranes (MR418) are being used on this site due to the weight of the pre-cast construction and modular units, which have all been assembled off-site, weighing approx. 12-13te. The use of heavier cranes will speed up the process considerably. Our technical engineers have devised the overall design & strategy of this scheme to minimise disruption to the local area and reduce the need for road closures and traffic management systems.
We erected TC1 with a 450te mobile crane in Pratt Street, requiring a full road closure and traffic management system, which took 4-5 days. Diversion routes for traffic, pedestrians, safeguarding measures & physical segregation were all managed by Radius Group.
In order to save the customer money and time, and to minimise disruption around the site, we used TC1 to erect TC2. This kept the site cleaner and made the erection process more straightforward for the customer. Upon completion of the building core, TC2 removed TC1 and erected it on top of the concrete (slip form) core, creating TC3, which will further enabled the construction of the project.
Due to the constraints regarding the surface area on top of the concrete core, we had to work closely with the manufacturer to develop a bespoke technical solution, enabling facilitating the crane on the concrete core via a welded fixing angle (anchor) & grillage system.
TC3 will be used to remove TC2. And finally, TC3 will be taken down eventually, with a mobile crane and road closure.

Radius Group are a dedicated team of experienced site specialists backed by an industry-leading technical department. We offer a comprehensive ‘turnkey’ service, from initial consultation to project completion.
Radius Group implemented a strategic, phased approach for crane erection. TC1 was erected using a 450te mobile crane, then TC1 was used to erect TC2. Finally, TC2 removed TC1 and re-erected it as TC3 on top of the concrete core, streamlining the process and minimizing disruption.
Radius Group's technical engineers devised an overall strategy to minimize local disruption and reduce the need for road closures. They also saved the customer money and and time by using TC1 to erect TC2, which kept the site cleaner and simplified the erection process. This approach was crucial for the restricted site.
Three heavy-duty Potain MR418 luffing jib tower cranes were deployed for this project. These were chosen due to the significant weight of the pre-cast construction and modular units, which weighed approximately 12-13 tonnes each. The use of heavier cranes was intended to considerably speed up the overall construction process.
Due to surface area constraints on the concrete core, Radius Group collaborated with the manufacturer to develop a bespoke technical solution. This involved facilitating the crane on the concrete core via a welded fixing angle (anchor) and grillage system. This innovative approach enabled the successful placement and operation of the crane in challenging conditions.
