Imperial College London – White City
After successful tender processes, Imperial College London awarded us the first two phases of its scale space remediation and infrastructure works at its White City South Campus.
Works began in August 2018 with a multi-phased duration of 120 weeks. The project was a traditional design and build contract.    We were also awarded the Block A and G enabling works on the North Campus. These works were undertaken in three phases and were also a traditional D&B contract. 
Technical challenges
The location of the ICL site presented us with a unique set of challenges throughout with the project being in close proximity to both Network Rail and Transport for London assets.
Another challenges we faced was limited access and egress over the existing weight restricted Depot Road Bridge restricting the movement of plant to and from the site.  

We mitigated this by moving plant during nightime hours to cause as little disruption to neighbouring businesses, residents, the campus itself and any adjacent public transport routes.  

The campus has remained live while our works are undertaken, including ongoing scientific research, which meant works were planned around campus activities and curriculum events such as exams.  

The ground conditions were also a significant consideration. Thorough testing regimes for both excavated and retained materials were developed and implemented to satisfy the strict Environment Agency (EA) requirements and those of the client regarding the issued remediation strategy.

The full scope of works involved site clearance, break up, crushing and screening of concrete slabs, locating and removing existing foundations, pile probing, pile and crane mats, sheet piled wall, road networks, communications network and statutory supplies and hard and soft landscaping.   
Both projects at White City were traditional design and build contracts.
Pre contract

The site was adjacent to the main campus entrance, so we invested time pre-contract with the campus facilities management and security teams to ensure disruption was kept to a minimum and that any works outside the parameters of our boundary were undertaken under a strict permitting regime.  

Project planning

All of our ICL contracts were constrained by the requirement to work in proximity with other contractors on the site and the wider campus, meaning we had to adhere to strict deadlines with sectional handovers and partial possessions. This was achieved as a result of robust planning, programming and constant coordination.  

Local workforce

Throughout the project, we utilised a local workforce, many of whom lived within London and developed as a team and as individuals whilst working in an exciting, high-profile location.
