About Us
Barclay Advisory is building the next generation of project controls.
We are a disruptive UK consultancy with a clear ambition to revolutionise how major projects are delivered across infrastructure, construction, nuclear, rail, aerospace and defence.
We combine established project controls expertise with AI-enabled talent capable of creating better systems, smarter workflows and entirely new ways of working.
Our people do more than operate existing processes. They identify problems, create solutions, automate inefficient work and improve how project information is captured, connected, analysed and used.
We are building a new standard for project controls and a new generation of professionals equipped to shape the future of UK project delivery.
About This Role
The Senior Planner (Construction) will take ownership of the construction programme, working closely with the Project Manager and construction team to drive delivery through to completion.
This is a hands-on, delivery-focused planning role requiring someone who can combine strong Primavera P6 capability with a detailed understanding of how major construction projects are delivered on site.
You will develop, maintain and actively manage the construction programme, ensuring that activities are logically sequenced, achievable and aligned with the overall project strategy. You will work directly with construction managers, supervisors, engineers, subcontractors and project leadership to challenge progress, identify constraints and establish clear plans for upcoming work.
The role requires someone who is comfortable taking ownership of the programme rather than simply reporting against it. You will be expected to understand what is happening on site, challenge delivery assumptions, identify emerging risks and work with the wider team to establish recovery and mitigation plans where required.
The position will be predominantly site based at Hinkley Point C, typically three to four days per week.
Experience delivering major infrastructure or construction projects is essential, with previous HVAC or building-services experience strongly preferred.
