Outline• What is Safety in Design for buildings and
structures including schools
• Responsibilities for Safety in Design
• Legislative Framework
• Method for determining Safe Design
• Case Studies
Introduction to Safety in Design
for buildings and structuresAustralian WHS Strategy
2012-2022
Strategic Outcomes:
Hazards are eliminated and
minimised by design
• Structures, plant and
substances are designed to
eliminate or minimise
hazards and risks before
they are introduced into the
workplace
• Work, work processes and
systems of work are
designed and managed to
eliminate or minimise
hazards and risks.
Australian WHS Strategy 2012-2022
What is Safety in Design as it
relates to structures• Safe design means the integration of
control measures early in the design
process to eliminate or, if this is not
reasonable practicable, minimise risks
to health and safety throughout the life
of the structure being designed. Safe Work Australia 2012
Working Above the Line
Above the line – eliminating hazards at
the design stage is easier and cheaper
than making changes after the structure is
completed
What Safety in Design is not
• Designers being responsible
or taking a role in
construction safety during
construction
• About listing all the typical
hazards that a client should
be expected to already know
• About telling a constructor
things they should reasonably
be expected to already know
Who has Responsibilities?
• A PCBU that designs a structure
– Including architects, engineers, building
surveyors, building service designers etc
• A PCBU that commissions construction work
• Principal Contractor
– Commissions the construction work OR
– Is engaged by the client to be the principal
contractor and has authorised control of the
workplace
Responsibility to:• School employees
• Students
• Contractors
• School families
• Members of the public and people
who may be affected by the building
or structure
Legislative Framework
Act
Regulations
Codes of Practice
Australian Standards
Guidance Notes. Industry Standards
Compliance Required
Voluntary Guidance Material
Victoria – OHS Act 2004
WA – OSH Act 1984
All other states – WHS Act
2011 or 2012
Legislative Requirements• Design a structure that is
without risks to the health
and safety of persons
• Carry out or arrange
calculation, analysis, testing
or examination required to
achieve the above
• Provide information to each
person provided with the
design
Safety in Design Reviews –
Stages of Design• Safe Design of Structures – Code of
Practice 2012 from Safe Work
Australia recommends a three phase
process for integrating risk
management into the design process
– Phase 1 : Pre-Design
– Phase 2 : Schematic and Conceptual
Design
– Phase 3 : Design Development

Adapted from Szymberski 1997
Pre-Design
• Establish the design context
• Establish consultation methods with the
client
• Establish risk assessment protocal
• Obtain information including
– Intended use of structure or current use of
structure if it is a refurbishment/upgrade
– Industry injury/illness profile and statistics
– Guidance on structure hazards and possible
solutions
Concept/Schematic Design• Preliminary Hazard Analysis and consultation
• Identify hazards that are affected by the
design of the structure and are within control
of the designer
• Consider:
– Siting
– High consequence
– hazards
– Systems of work
– Environment
– Incident mitigation
Design Development• Determine how risks will be eliminated
or minimised through either
– Implementing solutions from recognised
Standards OR
– Conducting a risk assessment process
Why?
• Hazards with no suitable
solutions
• Poor safety record with the
hazard
• Requirement to build above
standard
Design Development
Conducting a risk assessment process
• Consider what could happen if someone is
exposed to the hazard
• Test design assumptions
• Consult with key people
• Conduct testing of structures or components
• Review previous design documentation
Design solutions to consider the hierarchy of control
Tender/Construction
Documentation• Review design solutions to confirm
that risk controls are effective in
reducing risk
• Redesign if required
• Continue consultation
Construction• Review any changes to the design
that are made during construction to
determine the impact on the agreed
design controls
• Determine if any new risks may have
been introduced during construction
Safety in Design Workshops
• Detailed hazard identification and risk
analysis
• Conducted with all relevant stakeholders if
possible
• Involve people who are experts in the
construction and maintenance of the
structure
Challenges for schools
• Lack of knowledge of the process for
designing and constructing a building
• School principal is in effect, the school’s site
manager
• Ongoing school
operation
• Time constraints
• Budget constraints
Safety
• Fitout to ensure smooth corners
• Adequate ventilation
• Avoid positioning operable windows in
traffic areas
• Minimising and controlling roof access
• Traffic management
• Non slip surfaces
• Access for emergency recovery
Security
• Logical access to site,
permit supervision of
entry
• Avoid nooks and
crannies
• Finishes and design to
discourage vandalism
• Lighting
Security• Compartmentalising
facilities for out of hours
use
• PA system
• Design allows easy
supervision by teachers
• Safe access to toilets
• Safe access to carparks
Hazards posed by innovative
design• Green walls/roofs
• Ergonomic issues
• Manual handling of furniture,
moveable walls etc
Hazards posed by innovative
design• Smaller spaces and break areas
make teacher supervision more
difficult
• Larger windows require additional
structural reinforcement
• Schools may be engineered beyond
the capacity of maintenance staff to
monitor controls and service the
equipment
