Investing in a modular operating theatre is not simply a matter of selecting prefabricated walls and installing equipment. The project must bring together clinical requirements, building services, infection-control principles, and long-term operational needs. Early decisions shape how safely and efficiently the theatre can function, as well as how easily it can be maintained or adapted.

Start with the procedures and workflow

Define the intended specialties and procedures before settling the room layout. A theatre for routine surgery may have different space, equipment, and service requirements from one supporting complex or image-guided procedures. Consult surgeons, anaesthetists, nurses, infection-prevention staff, estates teams, and biomedical engineers to map patient, staff, equipment, and waste movements.

Room configuration should support clear circulation and appropriate separation of clean and contaminated flows. Consider the position of the operating table, anaesthesia area, storage, access doors, and imaging equipment. Allow enough space for teams to work without obstructing emergency access. The number and arrangement of theatres should also reflect anticipated demand and the practical needs of associated preparation and recovery areas.

Coordinate the room envelope and building services

Modular wall and ceiling systems can provide smooth, durable surfaces with fewer difficult-to-clean joints. Specify finishes for their resistance to cleaning agents, impact, and routine wear. Agree early how doors, windows, service panels, and equipment supports will integrate with the system, and confirm that components remain accessible for inspection and repair.

Heating, ventilation, and air conditioning require particular attention. Airflow, temperature, humidity, pressure relationships, and filtration must be designed for the intended clinical use and applicable standards. These conditions depend on local regulations and procedure types; they should not be assumed from a generic theatre specification. Coordinate ductwork and filtration with ceiling layouts, lights, pendants, and structural supports to prevent clashes and preserve required performance.

Plan lighting for both general visibility and surgical tasks, including controls and backup arrangements where required. Electrical design should account for equipment loads, outlet locations, essential power, data, and future needs. Medical gases, pendants, and other ceiling-mounted equipment need coordinated positions that provide convenient access while keeping the working area unobstructed. Confirm load capacity, connection points, and maintenance access before fabrication.

Build in cleanability and maintainability

Cleanability depends on more than surface selection. Detail junctions, penetrations, doors, and fixed equipment so staff can clean them effectively and inspection is straightforward. Minimize unnecessary ledges and inaccessible gaps. At the same time, avoid treating every component as permanently sealed: engineers need safe, practical access to filters, controls, services, and replaceable parts.

Discuss maintenance responsibilities, spare-parts availability, warranties, and service intervals during procurement. A lifecycle view helps compare options beyond their initial cost and can reduce disruption during future repairs or upgrades.

Commission with the clinical team

Commissioning should verify that installed systems perform as specified, not merely that equipment powers on. Test ventilation and filtration, electrical and medical-gas systems, controls, lighting, alarms, and interfaces with theatre equipment. Document results, resolve deficiencies, and provide training before clinical use.

Requirements vary by jurisdiction, facility, and intended procedures. Developers should engage qualified designers and the clinical team from the earliest planning stages, then verify the design against current applicable standards. This coordination turns modular construction into a dependable clinical environment rather than a collection of prefabricated components.
