Cawarden rises to the challenge to prepare for the construction of Derby’s new flagship business school.
Cawarden was confidently entrusted by the University of Derby with the demolition of the student flats at Sir Peter Hilton Court on Agard Street. The following phase of work involved the completion of a complex proof dig and delivery of a high-spec engineered backfill to prepare the site for construction. Despite facing unforeseen archaeological challenges and extreme weather conditions, we utilised our extensive expertise and experience to successfully complete the task at hand.
As the Principal Contractor, our task was to carry out all the necessary enabling and demolition works to clear the large site. This included removing all slabs and foundations as well.
Following the clearance of the majority of the flats, our attention turned to the demolition of the front-facing structures on Agard Street, a busy thoroughfare. We carried out this work at night using a ‘stop and go’ method to ensure the road remained open and the public was safe at all times.
We ensured the building was stable and ready for rush hour by 6 am every morning.
As we approached the final phase of the demolition project, we were tasked with working in close proximity to a live pub. Despite the challenge, we tackled the job with utmost care and precision to ensure the safety of all involved.
All hard core was crushed and left on-site for later re-use into the new development.
The expertise of our Civils & Groundworks team ensured a complex proof dig was undertaken as part of an archaeological watching brief to clear any underground obstructions.
However, during the excavation process, significant archaeological finds were discovered.
Cawarden, the client, and the archaeology teams worked collaboratively and sensitively to overcome the challenges presented by the discovery of a large, historic, unknown cemetery.
This involved carefully excavating below the water table, which required daily de-watering of the site to maintain safe water levels.
After the archaeologists had completed their work, over 3,000m3 of highway-specification engineered backfill was used to fill the site. Compaction testing was then carried out in accordance with the required specifications.
Finally, a 6f2 piling mat was installed across the entire site to complete our work.
The flexible, ‘can do’ attitude through adversity and uncertainty and dedication to seeing the project through to completion is much appreciated.”
