    Brief

    BAM Nuttall Ltd is sought to provide high-level construction advisory services for the Wylfa enabling works project, with a focus on bulk earthworks and platform formation. The adviser will deliver practical, buildability-focused input to support early programme development, including indicative timelines, sequencing strategies, and delivery acceleration opportunities. The engagement will leverage currently available concept information without constituting detailed design or formal instructions. Key deliverables include advice on constructability, sequencing, and indicative durations for earthworks activities, with consideration of practical delivery constraints, material movements, and site handover requirements. The adviser will identify programme drivers, key risks, and optimization opportunities rather than validate or develop detailed engineering outputs. This is a time-limited 2-week engagement awarded directly to BAM due to programme urgency, their prior site knowledge from previous Horizon work, and the need for early contractor input to support the Rolls Royce SMR programme. All outputs will be made available to potential bidders for future earthworks procurements.
