is a two way thing…and in the built environment it is A team effort.The biggest short coming in any project is communication and briefingThe architect thinks the clients can interpret his planning,

The engineer thinks that the architect understands his calculations,The user client (

dr) thinks that the design team understands clinical procedures,So in the end every one thinks everyone knowns,b

ut really no one knows

Communication_ briefING

As maintenance installed it

What the customer wanted

WHEN WE DON’T COMMUNICATE

Challenges with briefing

We do not have smart clients

It’s often a once of project, with once of team

In the public sector the consultants as roster based and most often once offSlide8

Communication_ briefING

The

briefing guide is aimed at clarifying the client’s views and expectations. In general terms, clients rarely understand their needs and the appointment of an architect should remain the key to a successful project at the end. The architect’s role should therefore involve a series of pertinent questions towards the client, even if the process could reveal the impossibilities in carrying out the project.

 The architect’s services as well as the client’s budget are part of the briefing process, these should be highly stressed in order to avoid misunderstandings and possible fruitless expenditure. Moreover

, questions relating to site context, property ownership and related rights are important aspects in the process. It might be that there are servitudes that can restrict the design, adjacent buildings that can affect the envisaged project. Other aspects of the briefing process include, but are not limited to, the appointment of other consultants, the compatibility of the team with regard to CAD systems used, the accommodation schedule, the estimation of the quality of the building, the time-cost quality factor; and any other general matters specific to the project

.

The architect should have an honest and open relationship with client and maintain professionalism.   Architects often carry-out work purely to fulfil an architectural service than to help shape a better built environment. This is not only an act of dishonesty, but irresponsible

.

IAN ALEXANDER _ THE BRIEFING GUIDE

Key points

Make your client a smart client

Learn from your client

Discuss pertinent issues up front

Come to an agreed way forward before proceeding…

The life of a building

THEY TAKE A WHILE TO BUILD DEPENDING ON CONSTRUCTION AND SIZE

6 MONTHS – 8 YEARS….. UN FINISHED

BUT LAST LONG ONCE COMPLETED average life expectancy of public buildings in SOUTH AFRICA IS AT LEAST 40 years

THERMAL RESPONSE, ENERGY USE, ECOLOGICAL SENSITIVITY, OCCUPANCY

THEY ARE IDEALLY DESIGN AND BUILT CLIMATE SPECIFIC

TYPOLOGICALLY, ECOLOGICALLY, CULTURALLY, CONTEXTUALLY

THEY ARE EXPENSIVE TO BUILD

The life of a building_ lean design & efficiency

“Lean” is a way of thinking that was developed by the Toyota Motor Company, and to which many attribute its dominance of world car manufacturing today. Lean is all about eliminating waste, or “muda”.David Week, Architecture for Development

Traditional Design Process

Lean Driven Design ProcessDesign FocusFocus on processes that add value for the patient, staff and family members

Starts with programming

Starts with observation of operational processes

User groups are made up of staff leaders within a department or service

Value-stream focused teams include key stakeholders who are involved across the whole process of delivering the service to the patient are used to

analyze

the process

Each user group provides feedback to designers about their departments or services

Multidisciplinary consensus based, future-state processes drive the development of the floor plan

Floor plan diagrams are adjusted to accommodate existing operations and processes

Floor plan diagrams are used to validate the value stream, optimize future improvements

‘Another

approach to healthcare facility design, the 

Lean-Driven Design Process 

deliberately engages the facility stakeholders in the initial design process, with a focus on reviewing operational processes to eliminate waste and improve efficiency. This review yields a plan for how the hospital would like to operate that forms the basis for the architectural design

The life of a building_ maintenance

‘The key finding revealed that maintenance is implemented predominately on a corrective/emergency basis. This in turn has led to inaccurate maintenance estimates being projected by property practitioners resulting in the overrunning of maintenance budgets and premature replacement of building components.’

S.J Lazarus & A.C Hauptfleisch, The Application of Facilities Maintenance within the public sector: An exploratory study.

Department of Natural and Agricultural Sciences, University of the Free State,

A recent study (2010) investigated the implementation of maintenance practices with regard to the need, classification, planning, implementation, impact and cost estimating by property practitioners in the public sector, Eastern cape excess of +- 100 000msq infrastructure

Key challenges

‘The

failure to classify maintenance requirements accordingly.

‘

‘Key

errors in areas such as estimating maintenance cost and not creating an asset history regarding performance and cost are evident.

‘

‘Senior

management structures who are seen as hampering progress towards generating a fully fledged maintenance programme as in both studies they influence the budgets in a negative manner affecting both back log and planned maintenance.

‘

Proactive and planned…

NOT

reactive and correctiveSlide15

Aesthetics_ in the built environment

Reference: The building is a system…. A system of parts that all work together.

In The Ten Books of Architecture the ancient Roman architect Vitruvius stated that a building should meet obligations of commodity, firmness, and delight. Commodity addresses how a building serves its function and can be made more useful. Firmness means a building's ability to stand up to 

natural forces over time. Delight refers to aesthetics

.The National Institute of Building Sciences, USA

Aesthetics refer to sensory perception and understanding or sensuous knowledge.

In the built environment… the factors that impact our sensory perception and understanding though intrinsic design process are:

Structural integrity

Cost

Building material

Functional use

Building performance

Aesthetic qualities include

Unity, Proportion, Scale, Balance, Symmetry and Rhythm

Aesthetic elements

Vision, Hearing, Touch, Taste and smellSlide16

The bigger picture_

an urban perspective AND HEALTH

‘Factors such as population and technology influence and facilitate health care delivery and facility planning. Technology, in particular, plays a significant role because it is constantly evolving and leveraging the means and locations to deliver health care. No longer are planners simply talking about hospitals or outpatient

centers. The health care technology interface in the community primary care office or living room is here’Morris A. Stein_ Health Facilities Management

‘Health is associated with social determinants — nowhere more so than in cities,

and especially so when in conjunction with the increasingly important role of climate

change.

But for more than 150 years, a large and continually expanding body of research has shown that the way in which cities are planned and managed can make a substantial difference to the health of their

residents’

Rydlin

et al. _UCL (Shaping cities for health: complexity and planning of urban environment in the 21

st

century)

BUILDINGS ARE NOT ISOLATED ISLANDS; THEY FORM PART OF A LARGER SYSTEM, AN URBAN ECOSYSTEM.

HOW THE ECOSYTEM RESPONDS IS DEPENDANT ON THE SERVICES IT PROVIDES AND RECEIVES, AND THE SOCIAL DRIVERS OF THE SYSTEM.Slide19

The built environment_ and health

Studies indicate that health care facilities are contributing to the spread of Mtb (

Eshun-Wilson et al. 2008)‘The spread of infectious bacteria, fungi, viruses and single cell organisms (prokaryotic

& eukaryotic) specifically in hospitals are widely known to be first by human contamination (Hospodsky et al. 2012) and secondly dependent on environmental favourable conditions

(Basu. et al. 2007)……the built environment’
