Project summary

This project consists of two towers of 34 and 26 storeys. In the heart of the London Borough of Walthamstow, being built in a busy London city area, with a live shopping centre continuing to operate in the surroundings of the construction site.

The challenges

As this project was executed almost 3 times faster than a normal construction site, the value of the data collected and passed onto the client has immense importance, as every module that is installed needs to be in the correct position at the correct height. Accuracy and quality are crucial to ensure a smooth and successful installation, where first-time execution is critical.

Our work

Our Geospatial Engineers carefully established an initial control network, ensuring a precise and robust foundation for the towers by defining a comprehensive and accurate framework. Every single modular unit was positioned to detail and levelled to ensure that no future issues would occur with the modules that would be installed next. A continuous core shrinkage analysis was completed every 3rd floor of installed modules, to ensure that the core was shrinking/expanding at the predicted tolerances. Module Levels were also taken at every 3rd floor to ensure uniform shrinkage in accordance with model predictions. Core shrinkage took place at the beginning and end of the project.

Furthermore, a module load deformation analysis was conducted, to assess how the modules were deforming as the structure was continuing to be erected. As discussed above.  This crucial information was being delivered to the client on a daily basis. This has ensured that the client was regularly informed on the current status of the units and if there would need to be adjustments made so that the next level of modules would be able to be installed without any issues.

Our team

The Geospatial Engineer Team consisted of a Principal Geospatial Engineer and a Junior Geospatial Engineer, continuously throughout the entire module installation. With an additional teamvisiting the site on activities such as expansion of vertical control, core axial monitoring and module shrinkage, all under the direction of the Principal Geospatial Engineer.

Results

Successful delivery of another modular project in terms of geospatial engineering to a client that values our efforts to continually provide the power to make informed decisions.

Client Testimonial

“Murphy Geospatial have been assisting us for over 6 years now and their commitment to resolving difficult Geospatial issues continues to impress me through each and every project. The reliability of their staff in conjunction with the can-do attitude of their overall team makes MGS the go to company for all our surveying needs.” – Geoffrey Kingston – Module Installation manager – Vision Volumetric.
