We have extensive expertise in substructure construction and design, with a history of delivering basements dating back to the inception of R O’Rourke & Son in 1978. Over the years, we have employed diverse techniques to construct numerous concrete substructures, often characterised by their depth, complexity, or innovative solutions. While we utilise traditional methods for basement construction, we frequently implement top-down construction, particularly in congested city centre locations.
Consequently, we have developed significant knowledge and experience in overcoming the challenges posed by these environments, mastering various basement construction techniques such as top-down, partial top-down, propping/shoring, and ground anchors restraint.
We have a wide-ranging in-house design and engineering function that includes temporary works design, geotechnical design and reinforcement design teams managed by highly qualified and experienced engineers. All our engineers and designers are highly diligent with proven capabilities. Further engineering and design support is provided though access to our Materials Technology Centre's (based in London and Manchester), our in-house specialist land surveying team, precast design, and digital engineering.
We boast an outstanding track record in delivering top-down construction, offering our clients effective solutions for complex and challenging projects across the UK. The constraints associated with top-down construction demand advanced engineering design, and Expanded’s in-house design teams are experts in creating these construction forms.
We have extensive experience in implementing propping/shoring for basement and substructure construction. Our in-house temporary works team possesses the expertise and capability to manage the intricate design required for such comprehensive temporary works. We have successfully applied these techniques across numerous UK projects in the commercial, education, residential, retail, and marine sectors, often in constrained city centre locations.
