BUILDING AND CONSTRUCTION 3
Introduction
The demolition of a structure is a process whereby an existing structure is
purposefully destroyed in order to generate a diversity of fragments and components of
mixed materials. The demolition process takes the shape of a lifecycle, in which it undergoes
various stages of planning, design, construction, as well as maintenance. Since the past times,
various buildings have been demolished, which is still a functionally and structurally
accepted activity. Nonetheless, in recent times, there have been concerns on demolitions
relating to waste disposal from the demolition process as well as the environmental pressures
arising from the demolition (Allen & Iano, 2013). This has thus resulted in the determination
of the importance of demolition, which focuses on the failures and disasters from lack of
knowledge and awareness on the effective process of demolition.
An instance is demolition of a structure having hazardous chemicals to human health
as well as the environment. Hence, land creation is some significant issue which the
community should avoid as it results in serious environmental issues. An instance is the
demolition of royal Canberra hospital in 1997, which resulted in the death of a young girl and
nine other people hospitalized following a hit by debris (Banias et al., 2013).
In this research, we seek to offer a safe way of the demolition of a hospital, two-story
building located in Australia. The Rhyndara hospital will just act as a case study for the
simulated coordination & management demolition. Nonetheless, the demolition is bound to
adopt the Australian standards for safe demolition of structures.
Project site: Rhyndarra
Our case study will be the demolition of a Rhyndarra hospital, located in the city of Brisbane,
Australia. The building was constructed in 1888 to 1938, and it is known for being the second
women’s hospitals for the Australian military forces. The building is a two-story building and
originally functioned as a Salvation Army girl’s industrial school.

We will consider providing simulated coordination & management for the large hospital, by
adopting the Australian demolition standards, AS2601; demolition of a structure. The
diagram below illustrates the building

Terms of reference
In response to your request, we have taken the initiative to generate a report of the
Rhyndarra hospital, located in the city of Brisbane, Australia. In particular, this document
will document the general condition of the structures presented within the facility as well as
the buildings adjacent to it. Further, it should be noted that the construction dilapidation
report of 16th august 1988 by Anjana consultancies has been used as a reference point. Since
we are neither structural engineers, we have not provided the condition of the building in
Jregrds to its structural stability.

Public protection measures for adjoining public space along common boundaries
A written notice shall be served to every person within the hospital facility, beginning with
the hospital management. The owner of the hospital structure shall then protect as well
preserve the adjoining lot from any injury or damage. In the situation that damage to the
adjoining property seems imminent, the demolition process shall be halted immediately and
then continued at a later time when all the necessary measures have been put in place. As
soon as the demolition is done, the debris and the materials shall be removed with immediate
effect (Khalfan et al., 2018).
Before the demolition takes place:
The recommended pedestrian protection structures shall have been erected in
accordance with the theme: protection of the public, have been erected. The buildings which

BUILDING AND CONSTRUCTION 13
have been damaged by explosion, flood or fire shall be protected through means of shoring
prior to the commencement of the demolition process.
Around the property, barricade or protection shall be placed, and danger signs are to put all
around. For the purposes of dark hours, warning lights shall be provided, and two
independent exist as well be placed for the site. Additionally, to prevent unauthorized entry of
persons, watchmen shall be provided on the site (Khalfan et al., 2018).
Protection of public
There shall be marking of safe distances as well as posting of prominent signs. The
road adjacent to the site and the sidewalks shall be protected or closed. Additionally, in the
case of any circumstance, all the roads shall be closed or obstructed. The pedestrians shall be
offered an alternative path root. Disconnected of all the utility lines shall be done in
accordance with the concerned authorities.
Waste management processes to reduce environmental impacts
The wastes from the demolished structure shall be properly handled in order to
prevent environmental pollution. Additionally, the wastes mostly from the hospital are
hazardous as they contain chemicals which might be very harmful to human health. However,
a number of products can be recycled for meaningful purposes. Some of these include;
cabinets, light fixtures, and doors. Also, the shingles can be processed to make asphalt, and
the wood be repainted to be used in making new products such as mulch and chipboard
(Coelho & Brito, 2012).
Comply with local authorities for Traffic management.
In regards to the compliance by the traffic management authorities, the demolition
process management shall provide alternative paths for the pedestrians as well as creating
signs and obstructions around the demolition site. Additionally, the survey will be conducted
prior to the commencement of the demolition so that the road which might be used during the
transportation of the waste and the debris does not result in environmental pollution.

BUILDING AND CONSTRUCTION 14
Site Induction process for all site entries.
Before the commencement of the demolition process, all the workers as well as the
people on-site shall be given and induction training. Additionally, any visitor who intends to
come into the site and is authorized shall undergo through the induction training process. In
the induction process, the people shall e informed about the risks and hazards which they are
likely to face at the demolition site, what to do in times of emergency as well as how the risks
can be avoided as well as controlled (Khalfan et al., 2018).
Some of the information which shall be provided at the induction process includes
 RISKs and hazards which are available in the site such as chemicals, overhead power
lines among others
 The various control measures such as the no go zones, no walking near overhead
electric lines
 The site-specific rules which must be followed, for instance; personal protective
equipment such as the wearing of protective clothes and shoes
 Safety documents, plans, and rules
 Personals to report to in cases of emergency and incidents
 The procedures of emergency, evacuation as well as incidents
 The work layouts, the entries, location of facilities, security requirements, as well as
the first aid.
An example of the demolition site induction is provided in the illustration below.

BUILDING AND CONSTRUCTION 15
Risk analysis for the simulated onsite activities
Before the process of demolition begins, a thorough risk assessment and analysis
process shall be done. One effective way of managing the risk which is associated with the
process of demolition is by conducting a risk assessment process. The process hall involves
four basic steps
I. Identification of the problem – also known as hazards identification
II. Determination of the extent of the problem – also regraded as the risk assessment
III. Risk control process (Coelho & Brito, 2012).
IV. Review of the effectiveness of the risk control process

BUILDING AND CONSTRUCTION 16
Hazards identification
This will be the primary step in the conducting f the demolition. The process shall
begin by first identification of all the potential sources of hazards within the demolition site,
which is the hospital. Records of previous injuries in relation to the demolition of the hospital
shall be conducted, as well as asking the workers on some potential sources of hazards within
the workplace. Additionally, coordination worth other duty holders shall be done, for
instance: the structural engineers, mobile plant operators as well as the asbestos removalists.
Some of the demolition hazards include falling objects, unplanned structural collapse,
location of essential services above and underground, hazardous noise from explosives and
plants, exposure to hazardous chemicals, as well as the proximity of the hospital to other
structures (Khalfan et al., 2018).
Risk assessment
After the identification of the potentially hazardous substances, the assessment
process shall then begin, which should incorporate:
 Determination of the structural integrity of the structure to be demolished
 Work scheduling
 The number of personnel to be involved in the demolition process
 The exposures which are likely to be faced
 The prevailing weather conditions of the place
 The equipment as well as the plenty to be used in the demolition process as well as
the skills required from the operators of the machines
 The layout of the workplace or the demolition site
 The various methods of demolition
Controlling the risk

BUILDING AND CONSTRUCTION 17
The risk shall be control following a rick control hierarchy. The hierarchy is
recommended by the WHS Regulations, which stipulate how the risk is managed. If at all, the
risk cannot be minimized; then they are eliminated at all. Depending on the various potential
hazards, below are some of the measures which are taken during risk control (Coelho &
Brito, 2012).
a. Substitution of hazards demolition by safer means, for instance; using mechanical
means instead of manual handling
b. Hazards isolation; this will reduce the risk of collision, for instance; creating of a new
pedestrian pathway as well as mobile-powered plant
c. Use of engineering controls for fitting the falling objects, such as open cab excavator
d. Installation of administrative controls such as the installation of warning signs.
e. Provision of personal protective equipment such as hardhats, as well as high visibility
vests.
OHS compliance to protect workers for all onsite activities
To protect all the workers from onsite activities, there are various occupational health
and safety regulations which have to be adhered to. To meet these requirements, the
information below shall be provided by the demolition site manager
 What the demolition work involves (Khalfan et al., 2018).
 The duties which are associated with the demolition work
 The planning of the demolition work
 The practical measures to control the risk involved in the site
 Various range of demolition methods
 The special structures in the demolition process
Site supervision
There will be Daily site checks before commencing work or leaving the site by the site
manager (Coelho & Brito, 2018)

BUILDING AND CONSTRUCTION 18
Conclusion
Due to the various conventional as well as recent methods of demolition, attention has
been drawn to the effective methods of the demolition of projects. The process of demolition
in the life cycle of a building, as can be seen in the above project simulation work is as
important as the planning, design, construction, and maintenance stages. The process
generates a variety of waste products which can be detrimental to the environment as well as
the health of human beings. It is therefore imperative to adopt effective environmental
strategies of demolition which protects the environment and ensure sustainability. The
simulation of the demolition of the rhyndarra hospital above has been keenly explained in a
stepwise description. Various code of compliance needs to be adhered to ensure that
demolition of projects does not result in various incidents.
