Yes. We offer a fully integrated service, bringing together design consultants, engineers, project managers and skilled trades to deliver a cohesive, end-to-end solution for defence projects. This helps eliminate potential delays and miscommunications that can occur when separate contractors are involved.
A typical defence construction project progresses through several key phases: feasibility and design, planning and approvals, enabling works, construction and installation, commissioning, and finally handover and post-completion support.
Timelines vary depending on the project’s scale, complexity, and security classification. Smaller refurbishments may take less time, while major new-build or multi-facility programmes can extend over multiple years. We use detailed scheduling and risk management to deliver on time while maintaining full compliance and security integrity throughout.
