Operating room design and construction is a sequence of dependent steps, and mistakes made early, such as late equipment data or unclear ceiling loads, show up as delays at the end. This guide takes hospital project managers through a new fit-out or a renovation: briefing, design, first fix for pendants and lights, installation, commissioning and handover, with attention to the points that most often cause variations.
Step 1: brief, survey and approvals
Start with a clinical brief: specialties, case volumes, equipment, staff flow and future needs. For a renovation, survey the existing structure, ceiling void, services routes and air handling before design, since hidden conditions are the biggest source of change in refurbishments.
Identify the approvals needed. Facility licensing is handled by bodies such as DHA in Dubai and DOH in Abu Dhabi, and medical devices are registered with the relevant authority. Confirm current requirements and expected review times with your consultant, because they affect the programme.
Step 2: design and equipment coordination
Fix the design basis, such as the planning guideline and the engineering standards, and write the equipment list. Equipment suppliers must provide drawings, load and service data early. The central document is the reflected ceiling plan, where lights, pendants, diffusers, sprinklers and detectors are coordinated; see also our article on operating room design standards.
Select the pendant and light configuration at this stage. Lojer Solido pendants are built to order, and MZ Liberec TAURUS offers rigid, single-arm, double-arm and tandem configurations, so the choice must be confirmed before the first fix.
Step 3: first fix and structure
First fix covers the work that must be done before ceilings and walls are closed: structural supports for pendants, lights and imaging, conduits and pipes for medical gases, electrical containment, data and video cabling, ventilation ducts and bonding. Supports must match the supplier's fixing drawings and the structural engineer's calculations.
Cabling for video and integration should be installed at this stage. A system such as OpenOR uses a fibre network, so routes, conduits and rack locations need to be agreed before the ceiling closes. Record as-built positions with photographs.
Step 4: finishes, installation and clean build
After the first fix, wall and ceiling finishes, flooring and doors are completed, followed by second fix and installation of pendants, lights, outlets and equipment. Keep the clean-build discipline throughout: dust control, sealed openings and protected finished surfaces, because contamination during construction can compromise later air quality tests.
Installation should be done by trained engineers following the manufacturer's instructions. Our installation service page describes what we coordinate.
Common mistakes to avoid
The most frequent problem is late equipment data. If load, size and service information for pendants, lights, imaging or integration arrives after the structure is designed, supports and openings have to be changed on site. Set a data deadline for every supplier and tie it to the design freeze.
A second problem is poor coordination of the ceiling: sprinklers, diffusers, lights and pendants placed by different trades without one drawing. Hold regular coordination meetings with all suppliers present, and check parking positions of arms through their full range. Finally, do not leave user training and cleaning instructions to the last day; involve nursing and infection-control staff in the final walk-through.
Step 5: commissioning and handover
Commissioning covers medical gas testing and certification, electrical safety tests, ventilation balancing and room pressure checks, equipment functional tests and integration tests. Allow time for corrections and retesting in the programme.
Handover should include as-built drawings, equipment manuals, test certificates, cleaning instructions, warranty terms and user training. Agree a maintenance plan before the room opens, and ask Beckfinity for support on the ceiling equipment and integration scope.
Frequently asked questions
How long does operating room construction take?
It depends on size, complexity, approvals and the supply chain. We do not quote durations; agree a programme with your contractor and suppliers.
When should pendants be selected?
At design stage, before the first fix, so that structural supports and services are positioned correctly.
Can an operating room be renovated while the hospital operates?
Often yes, with dust and infection-control measures and phased work. Modular systems can reduce disruption.
What is first fix?
The work done before walls and ceilings are closed, including supports, pipes, conduits and cabling.
