The new contract represents a continuation of those services, specifically:\n\u2022 Technical support for Construction Phases 2 and 3 of the ATW.\n\u2022 Design input and query resolution for the Shaft Headworks package.\n\u2022 Updates to design documentation, including drawings, specifications, and risk assessments.\n\u2022 Attendance at project meetings and response to technical queries via CEMAR.\nThe scope is consistent with the original services and reflects the natural progression of the ATW project. SWA\u2019s continued engagement ensures consistency and avoids duplication of effort.\nEngaging an alternative supplier at this stage of the project would introduce a significant risk of receiving a service that is either incompatible with the existing design or deviates from the established technical approach. This could result in disproportionate technical difficulties in both the operation and maintenance of the facility. \nThe Consultant possess detailed and project-specific design knowledge, and their continued involvement is essential to preserve the integrity of the design intent, ensure continuity of technical advice, and maintain design authority. This is particularly critical as the project enters a key phase, including the completion of the Advanced Transition Works cell walls\u2014which will form the foundation of the future D3300 facility over the Shaft top\u2014and the planning and implementation of the Shaft Headworks package. These works have been developed in close collaboration with Sanderson Watts Associates throughout the history of the Shaft and Silo project.",

    "riskDetails": "There is a risk that delays to the physical Advanced Transition Works, Construction Works may occur, which would necessitate an extension to this Contract\nThere is a risk that delays to the Shaft Headworks trials and concrete cutting at the shaft top may occur, which would necessitate an extension to this Contract\nDuring the term of this Contract, the next phase of Shaft \u0026 Silo Design is expected to be awarded,  This may have implication for the ATW Design, requiring the Consultant to assess and respond to any resulting impacts on the ATW Works\nThere is a risk that the design life of the ATW needs to be further increased potentially changing the design and specification of the Works, requiring the Consultant to modify the design accordingly\nThe complexity of reinforced concrete works may lead to higher than forecast TQ\u0027s.  While the volume is uncertain, the risk is foreseeable and could impact the level of design support required.",
