PLS Civil Engineering recently completed a key phase of construction at the Future Biogas facility, Vulcan Renewables in Doncaster. This project focused on the delivery of a new deluge shelter, a critical piece of infrastructure designed to protect and house essential fire suppression equipment within a high risk renewable energy environment.
Project Overview and Purpose
In industrial facilities that handle flammable liquids or rapid spreading fire hazards, standard sprinkler systems are often insufficient. Deluge systems are specifically engineered for these high risk scenarios, designed to discharge water or fire suppressing agents through all nozzles simultaneously. This immediate, large scale response is vital for controlling or extinguishing a fire before it can escalate into a catastrophic incident.
To ensure the long term reliability of this safety critical equipment, it must be shielded from environmental degradation, accidental damage, and the elements. The construction of a dedicated deluge shelter provides this protection while also offering a safe, designated area for maintenance personnel to carry out routine inspections and repairs. PLS was appointed to deliver the civil engineering foundations and structural base for this essential asset.
Technical Scope of Works
The PLS site team managed the end to end preparation and construction of the reinforced concrete foundation for the shelter. This phase of the project involved several technically precise stages including the construction of robust timber shuttering to define the structure’s footprint. This was carefully set out to ensure exact dimensions were achieved, providing a clean and accurate finish for the final concrete structure.
High grade reinforcement bar was cut, bent, and securely tied in accordance with the project’s structural design. This provides the foundation with the tensile strength required to support the weight of the shelter and the operational loads of the deluge equipment. To ensure the new structure was properly anchored to the existing site infrastructure, the team installed dowels resin fixed into the existing concrete slabs. This technique creates a durable, structurally sound bond between the old and new concrete, preventing movement or settlement over time and improving overall stability.
The entirety of these preparatory works was completed to an exceptionally high standard, ensuring the site was fully ready for the final concrete pour.
Safety and Operational Delivery
Working within an active renewable energy facility like Vulcan Renewables requires a disciplined approach to site safety and operational coordination. The PLS team maintained strict control measures throughout the project, ensuring that our presence on site did not interfere with the facility’s ongoing processes.
Every stage of construction, from handling reinforcement steel to resin fixing dowels, was performed with precision. This level of workmanship is essential when building infrastructure that supports fire suppression, where equipment failure is not an option.
Project Outcome and Value
The successful delivery of this foundation phase ensures that the new deluge shelter will be supported by a robust, long lasting base. Once the structure is fully completed, it will play a fundamental role in the site’s safety strategy, providing the protection and access needed to keep fire suppression systems in peak condition.
This project further highlights PLS Civil Engineering’s expertise in supporting the renewable energy sector. By delivering precise workmanship and robust construction on safety critical projects, we help ensure the resilience and continued operation of major energy infrastructure across the UK.
