Help Build a Resilient Water Future through Leadership, Quality and Collaboration. Balfour Beatty plays a key role as part of Anglian Water’s one Alliance – a ground‑breaking collaboration between Anglian Water and eight industry‑leading partners:
Balfour Beatty, Barhale, Binnies, MMB, MWH Treatment, Skanska and SWECO. Together we deliver around 40% of Anglian Water’s capital investment programme. As we enter AMP8, our most ambitious Asset Management Period yet, we are taking on nature‑based, sustainable solutions such as wetlands and urban drainage schemes, setting global benchmarks in environmental infrastructure and empowering our people with exceptional career growth opportunities.

As a Site Manager you will lead site‑based delivery activities on complex infrastructure projects, ensuring construction works are delivered safely, efficiently and to a high standard. Working closely with the Construction Manager, you will coordinate subcontractors, manage resources and oversee day‑to‑day operations to meet project milestones.

• Manage and coordinate site activities in line with the construction programme, including subcontractor performance, resources and materials.
• Lead by example to ensure all safety, quality and environmental management systems are adhered to and embedded on site.
• Support project handover and ensure all works are completed to a safe‑to‑operate (STO) standard at DM4.
• Maintain site compliance with assurance requirements (CSIR, CEIR, CQIR) in partnership with the Delivery Assurance Manager.
• Monitor and manage budgets in coordination with the Cost Manager; approve site expenditure, timesheets and GRNs in line with governance.
• Review and approve subcontractor RAMS, manage site requisitions and ensure plant and materials are used efficiently.
• Take ownership of the rework list, ensuring timely resolution and submission for construction assurance.
• Collaborate with the Project Delivery Team to support programme, cost and quality reporting and risk management.
• Support change‑management processes and accurate use of CCMS for cost control and purchasing.
• Liaise with Anglian Water operations staff to ensure seamless asset transition and operational readiness.
• Lead and motivate the site team, promoting a culture of accountability, collaboration and continuous improvement.

• Demonstrable experience managing large‑scale construction projects with a value of £20 million or more, preferably within the infrastructure or regulated utility sectors.
• A proven track record of successfully delivering complex site operations in line with time, cost and quality targets.
• Strong understanding of health, safety, environmental and quality standards in a live site environment.
• Experience managing subcontractors and supply chain partners to meet programme objectives.
• Commercial awareness and confidence in managing site budgets, cost reporting and procurement systems.
• Familiarity with project assurance and governance processes, including change control and risk mitigation.
• The ability to lead, engage and develop site teams while maintaining excellent stakeholder relationships.

A construction‑related qualification is desirable. Experience working within an alliance or collaborative delivery model, along with knowledge of CCMS and digital site management tools, will be advantageous.

Day in, day out, our teams deliver some of the UK’s most ambitious, exciting and meaningful projects; developing, building and maintaining the vital infrastructure that supports national economies and strengthens communities.

• Smart working, giving you more flexibility such as staggered start and finish times, with up to 40% remote working where roles allow.
