At O’Brien Contractors, we deliver excellence right from the start, combining technical expertise, innovation and a relentless commitment to safety and sustainability. Our transformation of the Network Rail Depot Holgate, York, stands as a testament to our ability to manage complex infrastructure projects within live operational environments, delivering value and certainty for our clients.
O’Brien Contractors was appointed to convert a disused Network Rail storage yard into a modern, future-ready facility. The scheme comprised the construction of a 250-space vehicle parking area, integrated drainage and access infrastructure, sustainable landscaping and the creation of a 4,000m² storage zone for Network Rail’s future operational needs. The project was delivered on a live site, requiring seamless coordination with Network Rail management to ensure uninterrupted depot operations throughout.
Our in-house team undertook comprehensive site clearance and earthworks which included ground stabilisation. This approach reduced material to that needed to be removed from site, and the importation of aggregates. This gave the client a VE saving, and reduced the projects carbon footprint. We installed a robust drainage system, featuring attenuation tanks, swales, and flow control, all connected to the existing culvert, ensuring effective water management and resilience against extreme weather.
Hard and soft landscaping were delivered to the highest standards. Functional hard landscaping included kerbs, edgings and asphalt surfacing, with specialist treatments for pedestrian footpaths and road markings. Soft landscaping comprised planting, seeding and a rationalised tree root attenuation system, optimising both environmental and structural performance.
Access to the facility was improved with new dedicated entrances and exits constructed under a Section 278 agreement, seamlessly connecting the site to the public highway and supporting efficient traffic flow.
Sustainability
Sustainability was embedded in every stage of the project. By stabilising and reusing site materials, we minimised the environmental impact associated with importing aggregates and exporting waste. Our commitment to innovation was reflected in the integration of energy-efficient LED lighting, electric vehicle (EV) charging infrastructure and the use of low-emission plant and equipment.
We also prioritised social value, supporting the local economy by engaging local labour and subcontractors wherever possible and sourcing materials from regional suppliers. This approach reduced transport-related emissions, provided job opportunities and fostered skills development within the community.
Challenges and Delivery
Operating adjacent to a live Network Rail depot demanded meticulous planning, proactive stakeholder engagement and a collaborative delivery model. Our team maintained close communication with Network Rail representatives, safeguarding ongoing operations and ensuring the depot remained fully accessible to staff and the public. Phased construction planning and stringent safety protocols were critical to maintaining continuity, minimising risk and upholding the highest standards of health and safety. The project was completed on time and within budget, delivering a functional, resilient and sustainable facility that enhances Network Rail’s operational capability and future growth.
