COVENTRY STATION RENOVATION PROGRAMME
Coventry City Council and Network Rail
Enable Infrastructure was contracted by Network Rail and Coventry City Council to participate in the refurbishment project for Coventry Station, a key component of the council’s Coventry Station Master Plan. The project aimed to prepare the station for the 2022 Birmingham Commonwealth Games, during which Coventry Stadium and Arena served as venues for rugby sevens, judo, and wrestling competitions.
The project
Enable Infrastructure and Enable Power Systems teams successfully completed a complex project involving the construction of a substation, two sets of lifts, and a new car park for a new shopping centre.
The project required collaboration with various organizations and individuals, including Western Power Distribution, Avanti West Coast, West Midland Trains, British Transport Police, National Car Parks, and members of the general public.
The civils work and Mechanical and Electrical Systems (M&E) work were meticulously executed by Enable Infrastructure and Enable Power Systems teams.
The project reached its successful completion in June 2021.
The challenge
- The project’s intricate nature involves numerous parties.
- Within the Coventry Station area, there are sixteen unexploded bombs left over from World War II. Coventry had several military factories and was a key location for ammunition distribution during the war. As a result, it was heavily targeted by the Luftwaffe, with the station being a primary target during the bombing raid.
The solution
- By meticulously strategising and fostering effective partnerships with our clients and various stakeholders, we achieved the desired outcome of the project.
- To address the possibility of encountering unexploded ordnance, we had a dedicated UXO specialist engineer working closely with our teams from start to finish.
