Brooksby Incinerator PLC Systems and Scada Modifications

Location

Description

Incinerator Software Rewrite, Comprehensive Testing and Hot Commissioning works. The scope of works is detailed below: • Main, Hydraulic and Bin Lifter Programmable Logic Controller (PLC), Modification and Testing • SCADA System Software Modification and Test with PLCs • Develop new HMI Screens for Hydraulic System • Confirm operation and communication of all Control systems, PLC's and HMI's • Check automatic operation of all system components: Fans, pumps, instruments, kiln rotation, filer unit, CEMS, loading equipment etc. • Confirm that all sensors and feedback are received at the control PC. • Full Incinerator Operational Testing • Hot Commissioning Works • Operational and Performance Qualification Activities • Staff Training • Update of Functional Design Specification (FDS) documents Rationale To ensure the Brooksby Building meets its full operational requirements and satisfies SAPO4 licensing conditions, which are necessary for benefits realisation, full functionality of the incinerator is essential. A complete rewrite of the control software will enable Pirbright to safely understand, operate, and maintain the incinerator going forward. The incinerator is a critical component of the building, particularly as it operates across the containment barrier. Ensuring the incinerator is fully functional and capable of reliable automatic operation is therefore a key priority. Without this capability, the building cannot be safely or effectively brought into use for SAPO4 activities, nor can licensing requirements be met.

Legal Justification

The full commissioning of the incinerator and the software rewrite requires highly specialised expertise. Due to the technical complexity and niche nature of the works, there is an absence of viable competitive alternatives within the market. On this basis, Lührfilter is considered the most appropriate contractor to undertake the required works. Lührfilter has developed extensive knowledge and system-specific knowledge of the Brooksby incinerator through its involvement in Phase 1 (Investigation and Testing) and Phase 2 (Commissioning Works and Documentation Update). This includes a detailed understanding of the system architecture, control philosophy, and operational constraints. This knowledge is not readily transferable without significant time, cost, and risk. It is therefore critically important to retain this expertise for the software rewrite and final commissioning activities. Engaging an alternative supplier would introduce significant risks, including duplication of investigative work as any new contractor would require substantial time/cost to familiarise themselves with the system and revalidation activities. In contrast, Lührfilter's existing in-depth knowledge ensures continuity of service, reduces delivery risk, and supports an efficient programme. In addition, Lührfilter has a proven track record in delivering comparable incinerator systems, including four previous phases of successful works on the ISO11 incinerator since 2015. They therefore have demonstrable expertise in high-risk and high-containment environments, including a strong understanding of bio-containment requirements, operational protocols, and SAPO4 licensing and associated compliance standards. For these reasons, the proposed direct award to Lührfilter is justified on the basis of absence of competition for technical reasons, continuity requirements, and the need to mitigate significant delivery and operational risks.
