ABOUT 4CONSTRUCT'S CAT A FIT-OUT SERVICES
Our team can help your transform your interior space
At 4construct, an Oxford-based company, we specialise in delivering high-quality CAT A fit-outs, transforming commercial spaces into pristine, functional foundations ready for an incoming tenant's specific needs. Our process is meticulously planned and executed, ensuring a seamless journey from an empty shell to a fully prepared blank canvas.
Our experienced team develops comprehensive technical drawings and specifications. This phase focuses on the optimal layout for raised access floors and suspended ceilings, the efficient distribution of mechanical and electrical (M&E) services, and the integration of fire detection and protection systems. We ensure all plans adhere to current UK building regulations and best practices, prioritising both functionality and future adaptability.
Design and Technical Planning


Every project begins with a detailed discussion. We work closely with the landlord or developer to understand the building's characteristics, the target tenant profile, and the precise scope required for the CAT A standard. This includes evaluating existing infrastructure, assessing regulatory requirements, and defining the aesthetic and functional objectives.
Initial Consultation and Scope Definition
With approved plans, we initiate the procurement of all necessary materials and services. We leverage our robust network of trusted suppliers to ensure quality components are sourced efficiently. Concurrently, a detailed project programme is developed, outlining key milestones, resource allocation, and critical path activities to guarantee timely delivery within budget.
Procurement and Programme Management


Before any physical work commences, we establish a safe and organised site. This includes securing the area, setting up welfare facilities, and implementing rigorous health and safety protocols compliant with all UK legislation. Our commitment to safety is paramount, protecting our team, other site users, and the public.
Site Establishment and Safety Protocols
This is where the transformation takes shape. We begin with the installation of raised access flooring, creating the essential underfloor void for flexible cabling and services. Simultaneously, suspended ceilings are fitted, often incorporating integrated lighting. Our skilled M&E engineers then meticulously install the primary power distribution, essential lighting circuits, and the core heating, ventilation, and air conditioning (HVAC) systems. Fire detection and alarm systems are integrated and rigorously tested.
Core Infrastructure Installation


With the main infrastructure in place, we move to the final finishing elements. Walls are plastered, prepared, and painted in a neutral finish, ready for tenant branding. Core areas such as washrooms are completed to a high standard, showcasing the property's overall quality. A comprehensive snagging process follows, where every detail is meticulously checked against specifications to ensure perfection and rectify any minor imperfections.
Finishing Touches and Snagging
Upon completion, we conduct a thorough handover, providing the client with all necessary documentation, including 'as-built' drawings, operation and maintenance manuals for all installed systems, and relevant certifications. Our aim is to deliver a perfectly prepared, compliant, and attractive space, ready for the next stage of the tenant's CAT B fit-out.
