Defence & Public Sector Construction

Secure facilities and live estate upgrades with access control, secure ICT pathways, resilient MEP, fire strategy integration, IST and clean commissioning for predictable handover.

Defence & public sector — secure facilities & live-estate upgrades

We deliver new build and refurbishment across secure, operational estates. Works are planned around business-as-usual with controlled access, pass and escort regimes, tool control, and clear red/blue routes. Resilient MEP, secure ICT pathways and coordinated fire strategy keep facilities safe and available.

Typical scopes include security receptions and search areas, control rooms, resilient LV/HV and standby power, HVAC upgrades, compartmentation and firestopping, CCTV/ACS integration, and compliance testing to provide a clean, predictable handover.

FAQ

Everything you should know about Construction

  • Construction
  • What types of projects do you deliver?
    New build, refurbishment and fit-out across education, commercial offices, industrial and logistics, life sciences and data centres with programme-led delivery and integrated trades.
    How do you keep programmes predictable?
    Two-stage planning with gateways, look-ahead schedules, risk and issue logs, and weekly progress reviews. Early procurement of long-lead items and clear change control prevent drift.
    How do you work in live or occupied buildings?
    Phasing and decant plans, out-of-hours windows, red and blue routes, dust and noise controls, compliant hoardings, permits to work and daily briefings so operations continue safely.
    Do you support preconstruction and design?
    Yes. Feasibility, surveys, cost planning, value engineering and buildability reviews with clear assumptions and constraints. We coordinate design to de-risk site delivery.
    How do you manage quality and handover?
    ITPs and hold points, digital QA evidence with photos and certificates, progressive snag closure, commissioning plans and soft landings. Complete O&M packs for a clean handover.
    Which procurement routes do you work under?
    Two-stage and single-stage D&B, traditional, and PCSA arrangements. We also deliver through client frameworks where required with open-book options available.
    How do you manage health, safety and environment?
    CDM compliance, RAMS and permits, inductions and daily briefings, temporary works control, environmental protection and independent audits. We target zero incidents and zero rework.
    Do you use prefabrication or DFMA?
    Yes where it adds value. We assess skids, risers and modular elements during preconstruction to improve quality, reduce time on site and minimise disruption in live environments.
    How do you handle cost control and changes?
    Baseline cost plans with tracked assumptions, live change registers, priced options and approvals before issue. Forecasts are updated with each gateway so budgets stay under control.
    What support do we get after completion?
    Training and soft landings, defects response with clear SLAs, seasonal commissioning if needed, and retained records to maintain the golden thread for the asset lifecycle.
