This project involved the complete installation of electrical and building upgrade works at a Network Rail Maintenance Depot (MDU). Simon Dean acted as the Principal Contractor for the project which was divided into two distinct phases, each addressing specific components of electrical and civil infrastructure, including DNO (Distribution Network Operator) arrangements, rewiring, external lighting installation, and building refurbishment.
Phase 1: Electrical Distribution Works
The first phase focused on completing DNO and electrical distribution works. Civils teams carried out installations of new underground ducting to distribute power around the depot and to existing buildings. Multiple turning chambers were installed around the depot to support future installations and service distribution. Concrete foundations were installed for a new GRP cubicle and adjacent lighting columns as specified on design drawings provided by Network Rail.
Once the civils team had installed the new cubicle, our electrical installation teams installed new electrical distribution equipment to provide power to the depot. Our teams managed the DNO operator to seamlessly transition the depot over to the new supply.
Phase 2: Building Works
The second phase focused on refurbishments to the existing buildings and infrastructure within the depot. This included internal rewiring the buildings and external improvements, including lighting column installation and replacement roof structures.
Due to the age of the toilet building, the roof structure had become life expired and required replacing ensuring a 20-year guarantee. The structural joists were inspected after the roof structure was removed and confirmed to be in good condition, negating the need for replacement. The roof was overlayed with sheet timber and covered with a new EDPM membrane. Additionally, roofline fascia’s, guttering and rain water pipes were installed, providing durability and protection against weathering.
Associated builders’ work included renovations to the building fabric to accommodate the rewiring efforts. New uPVC Doors and Windows were installed for improved energy efficiency, security and aesthetics. The existing toilet block and managers office were rewired in full with new containment systems and fixed electrical appliances. Our teams worked collaboratively to bring the depot buildings in line with the latest building regulation standards.
New street lighting columns were installed around the depot to provide compliant lighting levels for a rail operated depot. The civils team installed new foundations for each column. Additional crash protection barriers were installed to protect the lighting columns in the depot.
The project was completed successfully, with both phases meeting Network Rail’s requirements. Several challenges, including space constraints for electrical infrastructure and unforeseen onsite conditions, were effectively managed by Simon Dean as the Principal Contractor. By implementing changes such as increasing ducting capacity and adjusting the scope of the roof refurbishment, the project was able to future-proof the infrastructure and deliver high-quality results while remaining within budget and completing the project on time.
