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 BRIEFING
THE 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,
BUT 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 OFF
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.

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…PREFERABLY NOTED ON PAPER
COMMUNICATION_ IN THE BUILT ENVIRONMENT
TOOLS OF COMMUNICATIONS• DRAWINGS
• FLOOR PLANS• SECTIONS• DETAILS• WINDOW SCHEDULES• DOOR SCHEDULES• DATA SHEETS• FURNITURE SCHEDULES
• 3D MODELS• EQUIPMENT LIST• BILLS OF QUANITY
All these tools become part of the contract and the required contractual obligations by the project team.

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
THE FUNCTION AND USE CHANGES IMPACTED BY SOCIAL SYSTEMS AND CHANGE, TRANSPORT SYSTEMS, TECHNOLOGY ADVANCMENT
THEY APPEAR DIFFERENT IN EVERY SEASON AESTHETICALLY ELEMENTS ARE PRONOUNCED OR FADES IN DIFFERENT SEASONS
THEY PERFORM DIFFERANLTY IN EVERY SEASON THERMAL RESPONSE, ENERGY USE, ECOLOGICAL SENSITIVITY, OCCUPANCY
THEY ARE IDEALLY DESIGN AND BUILT CLIMATE SPECIFIC TYPOLOGICALLY, ECOLOGICALLY, CULTURALLY, CONTEXTUALLY
THEY ARE EXPENSIVE TO BUILD MORE EXPENSE TO MAINTAIN 90% OF THE BUILDING COST LIES IN THE OPERATING AND MAINTENANCE COSTS

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 Focus Focus 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.’HKS Architects, Traditional versus ‘Lean-Driven’ Operational Process Improvement based Hospital 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 corrective
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 includeUnity, Proportion, Scale, Balance, Symmetry and RhythmAesthetic elementsVision, Hearing, Touch, Taste and smell

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 21st 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.
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’
