Design Process

Designing a hospital is a much more complex and drawn out process than, say,designing a shopping mall or a hotel. To give you an idea of what is involved and theextent of details that have to be encompassed; we will discuss some of the components

contributing to the complexity of this process. The design process of a hospitalinvolves all of the following activities but is not necessarily limited to them:

1. One of the main considerations before embarking on the process is number ofspecialties that are required in the hospital;

2. What departmental interdependence (such as imaging department to beaccessible by most departments but in close proximity to A&E and someoutpatient clinics) is required?

3. The sheer number of services required, such as medical gasses;

4. The co-ordination required between the lead consultant (usually the architects)and M&E, structural, and specialist consultants such as the Radiation ProtectionAdvisors, local authorities, fire brigade, infection control to name but a few;

5. What studies and surveys are required prior to commencement of the hospitaldesign process;

6. Whether the hospital project will be built on a greenfield site, demolition isinvolved or if an existing hospital has to be re-developed;

7. Consideration of legal aspects & legislations, building regulations, health servicetechnical memorandums;

8. Consideration of environmental legislations and changes in environment, weatherand temperatures;

9. Consumerism issues;

10. Disability issues;

11. Safety and security from terrorism to safety of drugs in pharmacies;

12. Hospital Personnel/Staff safety ;

13. Aspects dealing with safe usage of dangerous drugs, gasses, radioactivesubstances and the like as well as their safe disposal;

14. Recycling/Incineration issues;

15. Day to day hospital infrastructure and equipment maintenance issues;

16. Access and egress of big ticket medical equipment you can bring in and

assemble and install a large piece of kit such as a CT scanner duringconstruction but after the hospital is built how will you take it out of the hospitalwhen it needs replacing;

17. Services that each different piece of medical equipment requires power (singleor 3 phase, what amperage, socket or spur, UPS, IPS), data (RJ45, broadband),& medical gasses;

18. Structural requirements for walls, ceilings and floor such as a theatre lights andpendant hang by the ceilings, or ultra clean canopy in orthopaedic theatres isfixed to the ceiling. The weight of heavy equipment such as burns bed needsconsidered to reinforce floors.

Having considered all the above mentioned aspects of hospital design, the processkicks off with a brief from the client. The brief for a hospital is actually not brief by anymeans. It can easily run in to several hundred pages going into such detail as typesand number of clinical and non clinical rooms, department and room adjacencies and

description of functions performed in each room, its critical dimensions, and mainequipment requirements.

In traditional contracts, a firm of architects and health planners who have experienceof designing hospitals, will lead the project on the clients behalf and will employ themain contractors including the building firm. In the UK the building contractors employthe architects and other main contractors and consultants, under Private FinanceInitiative (PFI) schemes.

We will consider the hospital design process as followed under PFI schemes in the UK

for the purposes of this article. Note that this article is aimed to provide anapproximation of the process. The process can change and various steps can beperformed in different sequences.

The building contractor employs the firm of architects to translate client requirementsinto a practical design proposal that involves the building shape, 1:500 scale floorplans showing the shape, size and locations of all the required departments, rooms,corridors, clinical, non-clinical and support rooms such as risers, hubs, stairs etc.

These are developed over months in close consultation with the client. The shapes,

height, looks of the buildings have to be in keeping with its location, and compliant withthe local regulations, and approved by local council and fire brigade in addition toothers.

Once this high level design is agreed, the process moves on to 1:200 scale and lateron to 1:50 scale drawings, showing furniture, equipment and services outlets for eachroom showing the plan layout (as if you are looking at the room from the top). It is

prudent to also draw and review room elevations of heavily loaded rooms and specialistrooms such as theatre suites and High Dependency Units (HDU). This will help avoidany clashes of equipment with the fixed joinery, service outlets and fenestrations suchas windows.

The drawings are augmented by a document called Room Data Sheets. This documentprovides detailed design, engineering, equipment, fittings and fixtures information foreach room in the project. The data behind the room datasheets later providesinvaluable information when its time to develop production design and later when thecommercial department goes out to tender and procure everything from the light

switches to the Magnetic Resonance Imaging (MRI).

Up until the 1:50 drawings and datasheets are developed, the end users / cliniciansinvolvement is limited and ad-hoc. Once the detailed design starts at 1:50 level,programme is developed to hold series of user consultations where the architectspresent and explain the design to the users and seek their feedback. This involvesextensive changes to the design which then eventually gets signed-off by the client.

As and when the clinical design by departments is signed-off, the production design(mechanical, electrical, structural etc) kicks off which then starts to shape the routes,

spatial planning, plant size and location of the various services required to support thedesigned hospital. More often than not, production design can impact on the alreadyagreed clinical design, such as the structural columns required to hold the building orrain water pipes can appear in the middle of a clinical area and hence furthertweaking is always required.

Parallel to the clinical design myriad of other design and research is being carried outsuch as the signage, landscaping, radiation & laser protection, fire escape routes,

energy efficiency of the building, heat gains for the areas facing the sun, access andwelfare areas for the disabled (not just wheelchair users but also, blind, deaf, hard ofhearing, colour blind or frail).

All of these studies require co-ordination among various disciplines and sub-consultants and is usually done via the lead consultant normally the architects. Theneed for co-ordination is paramount and just to highlight why, imagine theconsequences of designing a large plant on the level above clinical area with ceilingmounted microscopes. The vibration from the plant above will effectively render themicroscopes useless.

What has been described above as design process can take a couple of years for ahospital with 3-4 specialities and around 600-800 inpatient beds. This is a rough guideand obviously can vary from project to project.

We will be writing on various aspects of the above process to explain it in more detail.So do visit us more frequently.
