Capital Project Delivery

From legacy systems to live-saving capability

Modernising critical laboratory infrastructure without disrupting operations

Client

DEFRA


Location

Addlestone




Completion

2024


Challenge

The project required the continuous availability of a critical national infrastructure facility, operating 24/7 with no disruption to its laboratory and emergency response capabilities. The constrained site demanded careful coordination to maintain safety, meet rigorous biocontainment standards (including CL4/SAPO5), and comply with stringent environmental and animal welfare regulations. G&T faced the additional challenge of managing numerous stakeholders, including regulators and Government departments.

Solution

G&T provided Project Management and Facilities & Asset Management advisory services to ensure the successful planning and delivery of this complex, high-security programme. We worked closely with the client to develop and embed delivery processes aligned with their existing quality and environmental management systems. Our team managed a diverse portfolio of projects—ranging from new incineration and HVAC systems to flood defences and early-stage enabling works—ensuring minimal disruption to operations. We also advised on the long-term maintainability and performance of assets, helping the client make informed investment decisions while maintaining compliance with rigorous regulatory and biocontainment standards.

Outcome

G&T enabled the ongoing modernisation and resilience of a highly sensitive national asset. Our proactive management safeguarded business continuity, extended asset life, and supported future capacity through new infrastructure delivery. The site continues to operate safely and effectively, with enhanced biocontainment systems, energy performance and regulatory compliance, ensuring it remains fit for purpose in a fast-evolving scientific and policy landscape.
