The Healthcare Issue COVER STORY: BOX HILL HOSPITAL DESIGNING FOR REMOTE LOCATIONS 8 TIPS FOR BUILDING UPGRADES SOLUTIONS FOR LIVE ENVIRONMENTS

SEPTEMBER 2014

Message From The Top Welcome to the Healthcare 2014 Edition of Shaping Australia.

A

ustralia’s healthcare systems are changing rapidly. “The industry is constantly battling to build on healthcare delivery value, employment generation and infrastructure development,” says a new Frost & Sullivan report.

Australia’s healthcare industry is therefore tackling increasing patient populations, budget constraints

and resource shortages. This makes efficiency a vital component in hospital management and effective service delivery.

This issue of Shaping explores the often complex challenges of working in a live healthcare

environment, the importance of pre-planning and solutions for ensuring ‘Operations Come First’. This was also the theme of our recent imagin8 seminar for which we thank our partners Billard

Leece Partnership and Built for making such a success. You can read more later in the magazine. As always we welcome your feedback. Denis Young, Managing Director – Australia denis.young@meinhardtgroup.com

BRIDGING THE OLD WITH THE NEW

The third key challenge the team successfully solved was

the improvement works to a platform spanning two of the hospital’s existing buildings, which housed mechanical

equipment essential to the smooth running of operations. To further improve servicing, 80 tonnes of additional

equipment was proposed for the existing platform. The

bridge was not designed to cater for such a load. This meant strengthening the existing frame to support the extra weight,

enabling the existing buildings to in turn carry the now heavier platform, while at the same time ensuring no operational disruptions. This was made all the more challenging as

underneath the bridge was the maternity ward and at one end were a series of major operating theatres.

The expanded hospital – designed by Silver Thomas Hanley with Jackson Architecture - accommodates 621 beds,

an increase of more than 220 beds, and provide a larger

emergency department that includes treatment, assessment and short stay beds; a dedicated precinct for women and children’s services; eleven new operating theatres; a new

intensive care unit; expanded services for cardiology, cancer and renal patients; additional inpatient wards; and two floors of parking under the building with 225 patient car spaces. SHAPING | HEALTHCARE - SEPT 2014

FROM BOX HILL HOSPITAL:

“The Meinhardt team has contributed

substantially to the extremely successful

hospital project at Box Hill. Their personnel have integrated completely into our “one

team” approach and have participated in the

problem-solving value-for-money environment that has been the basis for its success. This

has not been an easy project and the team has had to be flexible in its approach particularly

when there was a request to grow the building during its construction which required

Meinhardt to pull out all the stops to find a solution that would not delay the project.”

“It was a challenging schedule,” admitted Rennie Darmanin,

Out On A Limb: Designing Hospitals for Remote Locations Working in remote, rural locations throws up its own set of unique challenges as Les Simonsen, Deputy Manager – Structures, discovered while working on four regional hospitals for Queensland Health. Les Simonsen Deputy Manager- Structures les.simonsen@meinhardtgroup.com

E

ach of the sites at Mt Morgan, Baralaba, Biggenden and Winton, designed in collaboration with architects Thomson Adsett, comprised large single-storey structures, utilising a combination of slabs on ground and suspended slabs with steel wall and roof frames. “Ultimately, the idea was to simplify and prefabricate as much as possible and then bring the components from the factory to site,” said Les. “This was because of the lack of skills and materials locally. Initially though we investigated the use of steel portal frames. This would have enabled a more future-proof solution allowing internal walls to be easily pulled out if required since they are not loadbearing. Upfront costs, however, became the primary business driver. Prefabricated walls and roof trusses, with internal frames to cater for larger spans, such as where x-ray machinery had to hang, were determined to be the best solution to meet this client requirement.” SHAPING | HEALTHCARE - SEP 2014

Given the similarity of the projects, the team duplicated as many of the details as possible to enable the design of the four hospitals to happen concurrently and speed up the programme. Programme planning, unsurprisingly was critical, as all four sites had existing hospitals that had to remain operational. Staged demolition and construction was instrumental in achieving this successfully. The demolition and site clearing also necessitated that all heritage and environmental issues were properly managed with the rural locations throwing up very particular challenges. In Winton, for example highly reactive geotechnical conditions were encountered which posed restrictive design parameters and required clever structural thinking to overcome. This was done successfully through a heavy grid of footings to reduce any building movement. Mt Morgan, on the other hand, is situated on the

side of a hill. This tricky topography meant a design which simplifies\d construction techniques, with high block retaining walls and suspended slabs over steel beams. This was imperative in aiding a quality build outcome within the timeframe needed. Baralaba, meanwhile, is by a river prone to flooding. With no record of what the flood level was, the team had to base the solution on anecdotal evidence. Research uncovered details of the town’s biggest flood in the early 20th century. “We have designed 500mm above this level to ensure, as realistically as possible, hospital operations will never be affected.”, said Les. All of this work had to be done in the context of detailed project and programme management to coordinate site inspections and reduce cost and travel requirements to these remote areas.

The obvious and easiest solution was to take the John Fowler approach and simply shut down the operating theatres for 4

Of course, Box Hill Hospital couldn’t fathom the thought

of operating theatres being knocked out for 4 weeks. The entire process needed rethinking.

Monash Children’s Hospital Epworth Rehabilitation Hospital is another case in point. A conglomerate of old brick buildings has been transformed into a brand new facility, which opened last year (Figures 6a and 6b). But what you can’t see from the unassuming street view is the enormous 3-storey basement car park excavation below (Figures 7a and 7b).

The site was pushed to its limits by digging out the

maximum possible footprint, hard up against the existing

hospital on 2 sides and the main roads on the other sides. It certainly wasn’t the easiest approach, especially when

significant amounts of rock were encountered, but it was worth it for the subsequent benefits.

Of primary benefit was again minimising impact on key hospital operations.

And, of course, major car parking problems at the hospital are now a thing of the past.

A final example is at Monash Children’s Hospital in

Melbourne where a 3-storey extension, incorporating 24

new beds including an intensive care unit, was built over the existing single storey main entrance of the hospital. The way it was designed made all the difference. Here, the hospital entrance remained functional by stacking new columns directly over the existing columns, and

• Short term pain (but rip the band-aid off quickly) There is often a discussion on brownfield projects about

brownfield project. It can be the difference between saving a bundle down the line or throwing money down the drain.

What Role Can Façade Design Play In The Healing Process? Typical building façades require the design team to strike the right balance between a host of parameters that pull the design in different directions, including structural, aesthetic, thermal, technological, acoustics, security, and more.

strike the right balance between a host of parameters

structural, aesthetic, thermal, technological, acoustics,

security, and more. Healthcare facilities have not only these to contend with but a unique set of challenges that require

consideration of multi- stakeholder needs, including patients, operators, health authorities, builders and architects, with often conflicting demands.

Through a combination of early façade consultant

engagement and the incorporation of imaginative thinking and the latest technology, the façade can literally unify these demands.

PATIENT COMFORT

Patient comfort is one of the prime concerns when

designing hospitals and healthcare premises. Patients

require a quiet atmosphere, plenty of natural daylight, as well as thermal comfort in order to recover in the best possible environment.

solutions such as multi-functional low-emissivity coatings, or even responsive façades, if budget allows.

This may involve a slightly higher capital expenditure, but

has the potential to reduce operating expenses, as well as provide the actual benefits sought for patients, hospital staff and visitors.

The design brief for a recent healthcare facility required

the courtyard to be accessible to patients in all weather, despite the hospital being located in a tropical location, with frequent storms. This was intended to allow the

patients to take a stroll or get some exercise every day. “We elected to adopt ETFE cushions instead of glass panels for the skylight covering the courtyard, so as

to minimise the framing sizes and maximize the panel

modulations,” said Mathieu Meur, Managing Director at

Meinhardt Façade Technology. “This provided an elegant

solution, without the need for additional columns or heavy steel members, all within budget.” (Figure 1)

Natural daylight is often cited as helping with patient

recovery. Achieving high access to daylight within the rooms, while ensuring the thermal comfort of patients is essential. “In one case, our strategy has been to adopt highly

spectrally selective glass, and spandrel panels extending up to the bed level,” said Meur. “In another project, the

strategy has been to have planters running horizontally

along the façade at every other level, and having rows of

creeping plants extending up onto stainless wires in order

to provide shade to the patients, while offering a soothing, natural experience.” AESTHETICS

More than many other buildings, the appearance of

healthcare facilities is of the utmost importance. Whether you patronise them as a patient, go there daily as a staff,

or visit a sick acquaintance, the last thing that you hope for is a drab-looking building. The building envelope should

be as pleasant and welcoming as possible, so as to make the experience of staying, working or visiting the building as agreeable as possible.

“This, of course, depends largely on the architectural

design, combined with the technical know-how of the

essential premises that need to be designed to remain

INTERNAL ENVIRONMENT

Air infiltration is another key consideration when designing healthcare facilities, as some of these buildings impose much stricter air infiltration or exfiltration limits as compared to other building types.

This could be due to the need to prevent harmful bacteria affecting patients, or conversely to prevent infectious diseases from spreading to the outside. Designs are

thoroughly tested, both on- and off-site, to ensure that the design parameters are met.

In one recent hospital project, the brief called for naturally ventilated wards, but a façade solution which should still keep rainwater out. Given the additional requirement for ample natural daylight, the developed design involved staggered, overlapping glass louvers, with open gaps

In many countries, healthcare facilities also represent operational in the face of disasters.

In particular, we have had to design hospital façades

to resist terrorist threats, such as improvised explosive devices (IEDs). This involves the implementation of

hardening measures in and around the buildings, including the building envelope itself.

“The solutions devised by technical teams need to

constitute not only a translation of the architectural vision

for the buildings, but also the synthesis of the multitude of

requirements by the various stakeholders,” concluded Meur. “The building envelope is designed so that patients enjoy a

peaceful and pleasant environment favourable to their recovery. And at the same time, the hospitals themselves garner a welcoming and attractive, yet highly efficient outcome.”
