Why Hospital Design Matters Before Construction Starts

Many hospital owners in Pakistan are under pressure to start building quickly. The plot is bought, the doctors are ready and every month of delay feels like lost income. It is tempting to begin the grey structure with a rough layout and “sort out the details later”. In a hospital, that approach is one of the most expensive mistakes an owner can make. Hospital design in Pakistan needs to be substantially complete before construction starts, because the structure, services, licensing and medical equipment all depend on decisions made on paper. This article explains why, what goes wrong when design is rushed, and what a complete design package should contain.

A Hospital Is a Machine for Care

An office or a shopping plaza is largely open space that tenants fit out later. A hospital is different. Every room has a specific purpose, specific services and a specific relationship to other rooms. An operation theatre needs controlled airflow, medical gases, isolated power and a clean route from the sterile store. An ICU needs observation from the nurse station and outlets at every bed. A radiology room needs shielding and a reinforced floor. These requirements reach right into the structure and the main services, so they cannot be added after the building is up without demolition.

What Goes Wrong When Design Is Rushed

Each of these leads to breaking finished work, redesign, extra cost and delay. In many cases the rework costs more than the design work that would have prevented it.

Design Decides Patient Flow

The way patients, staff, visitors, supplies and waste move through a hospital affects safety, infection control and efficiency every day for decades. Once walls and lifts are built, flow is very hard to change. A good design keeps emergency, imaging, theatres and ICU close together, separates clean and dirty routes, keeps outpatients away from inpatient areas and provides lifts large enough for beds. Our article on patient flow in hospital design explains these principles.

Design Decides MEP Capacity

Mechanical, electrical and plumbing systems are among the largest costs in a hospital. Their size depends on the final layout: how many theatres, ICU beds, isolation rooms and imaging machines there will be. Without that information, engineers can only guess.

Systems that must be designed early

• HVAC zones, air handling units, chillers and duct routes; see hospital HVAC and infection control
• Electrical load, transformer, generators, UPS and essential circuits
• Medical gas plant, manifold rooms and pipeline routes; see medical gas pipeline systems
• Water storage, treatment and drainage
• Fire alarm, sprinklers and smoke control

These systems need vertical shafts and horizontal ceiling space. If the structure is built first, shafts may be in the wrong place or too small, and floor-to-floor heights may not leave room for ducts.

Design Decides Licensing Success

Provincial healthcare regulators such as the Punjab Healthcare Commission license healthcare establishments against minimum service standards. These cover the rooms and facilities required for each service, as well as infection control and safety. Designing to these standards from the beginning is far easier than altering a finished building. See our guide to Punjab Healthcare Commission hospital requirements.

Design Decides the Budget

An accurate budget needs accurate drawings. A BOQ prepared from a sketch will miss quantities, specialist systems and finishes, and the real cost appears only during construction, when there is little room to negotiate. Complete, coordinated drawings allow an itemised BOQ that shows exactly what is included. They also allow the owner to compare options, such as different HVAC systems or finishes, and make decisions before money is spent.

Typical Late Changes and Their Knock-On Effects

The scenarios below are common on hospital projects that start without a complete design. Each looks small at first, but affects several trades.

Adding an operation theatre

An extra theatre needs more floor area, a larger air handling unit, extra chilled water capacity, medical gas outlets, isolated power and a connection to the sterile route. If the floor is already built, beams may block ducts and the plant room may be too small.

Upgrading to a CT or MRI scanner

Imaging equipment is heavy and needs shielding, stable power, dedicated cooling and a delivery route. Without planning, floors may need strengthening and walls may have to be rebuilt with shielding.

Converting a ward to ICU

ICU beds need more space, more outlets, more power, higher air change rates and visibility from a nurse station. A ward designed only for general beds rarely has the service capacity.

Moving the emergency entrance

If ambulance access is not planned with the site layout, the emergency department may end up far from imaging or theatres, or the ambulance bay may conflict with parking and traffic.

In each case, the cost of the change includes demolition, redesign, new materials, extra time and sometimes a delayed licence. Getting the brief right at the start avoids most of these problems.

Rushed vs Planned Hospital Projects

What a Complete Design Package Includes

• A clinical brief listing services, bed numbers, theatres, ICU and diagnostics
• Departmental layouts approved by the clinical team
• Room data sheets listing finishes, outlets and equipment for each room
• Architectural, structural and MEP drawings coordinated with each other
• A medical equipment list with space and service requirements
• Fire and life-safety strategy
• Submission drawings for building approval
• An itemised BOQ and specification

The Design Process

Can Construction Start Before Every Detail Is Final?

On larger projects, some overlap is possible. Foundations and the structural frame can begin once the layout, structural grid, shafts and plant locations are fixed, while interior finishes and some equipment details are completed during construction. This is a controlled overlap, not starting without design. The key elements that must be fixed first are the clinical layout, the structural grid, floor heights, shafts, plant space and the main MEP strategy. Changing any of these after concrete is poured is expensive.

Design-build as a solution

Owners who want speed without risk often choose a design-build or turnkey contract. The same company designs and builds, so design and construction can be programmed together and responsibility is clear. ACCO offers this through its hospital design and construction services, with design drawings free on award of construction.

Involving Doctors and Nurses in Design

The people who will work in the hospital know how departments should function. Senior doctors, nursing leads and infection-control staff should review layouts at concept and detailed design stages. Their input on room sizes, storage, nurse station positions and equipment often prevents problems that only appear after opening. Time spent on these reviews is small compared with the life of the building.

Conclusion

Hospital design matters before construction starts because almost everything that makes a hospital safe, licensable and efficient is fixed by the drawings. A complete, coordinated design and an itemised BOQ give owners control over cost, time and quality. To review a hospital project before work begins, contact ACCO on 0322-8000190 or info@acco.com.pk.
