Legoland | Merlin Attractions

Merlin Attractions appointed us to undertake the ground investigation to support the expansion of NINJAGO World at LEGOLAND® Windsor Resort. The project involved the removal of an existing attraction and the development of new visitor facilities and supporting infrastructure within a live operational theme park. 

Working within a busy visitor environment, careful planning and coordination were required to complete the investigation safely while minimising disruption to park operations. The project team required detailed geotechnical and geoenvironmental information to inform the design of the proposed development and identify any potential ground-related constraints at an early stage. 

To meet these requirements, we delivered a tailored site investigation programme comprising sonic boreholes, window sampling, and dynamic probing across the proposed development area.  

Following completion of the fieldwork and testing, our specialists prepared a Phase I Geoenvironmental Assessment alongside a detailed Phase II Ground Investigation, including both factual and interpretative reporting. The reports provided a clear understanding of the site’s ground conditions and identified any potential risks that could influence the design and construction process. 

The investigation successfully provided the design team with robust geotechnical parameters to support foundation and infrastructure design. Our contamination assessments also helped to inform appropriate earthworks and materials management strategies, reducing uncertainty and enabling the project to progress efficiently. 

By delivering a comprehensive ground model and practical engineering recommendations, we provided Merlin Attractions with the information needed to confidently advance the NINJAGO World expansion from planning and design through to construction.
