Demolition Plan and Safety Measures for Residential Buildings

Part A
Demolition work shall be performed in accordance with the Australian AS2601 standard:
demolition of structures (AS 2601). If the work is not covered or included in AS 2601, the work
shall be carried out in a manner acceptable to the Commissioner for WorkSafe Western
Australia. As compliance with AS 2601 is mandatory, the Regulations or these Guidelines do not
repeat the details of AS 2601. It is imperative that you are aware of potentially harmful materials
on your project site, among other preliminary steps, before starting any demolition or renovation
project.
Demolition plan
1. Establish a demolition budget
Set the maximum amount you're willing to spend and don't go beyond that budget. The different
costs that factor in a demolition or remodelling of a house can be quite different than you think,
so start a running list of the work you need (or want) to do. Then do some research to determine
the average cost of doing the job and add it to get a decent idea of what it would cost. Estimating
labour costs can be tricky, but planning for labour accounts for 15-30% of the total budget is
generally safe. The demolition for our case is a residential hip and valley home, the budget
should also include a 10-20 percent contingency.
Item Quantity Cost (Australian dollars)
1 Site inspection 100
2 Obtaining the necessary
permits
100
3 Salvage arrangements 100
4 Safety measures 100
5 Actual demolition 1000
6 Debris disposal 200
Preparing site for next
construction works
100
The budget will guide on which services to choose. There are variety of options to demolish a
building. Having a budget will guide to making correct decisions. The prospective situations that
could happen are many when it comes to bad estimation of project expenditures and all of them
have adverse implications. First and foremost are the impacts on satisfying the expectations of
the client. Not being able to deliver the agreed deliverables and quality standards of the project
could have a significant impact as a professional on your own credibility and future
development. Moreover, this may affect the reputation of organization performing the demolition
and have a negative impact on all your team members.
2. Project site walkthrough

This involves detailing the house to be demolished, professional inspection and other safety
preliminaries.
2.1 Structural house description
Figure 1 hip and valley roofing
Hip and valley roof rafters are loaded roof members running at an angle – (usually 45 degrees) to the
support walls and running at a pitch as well. The difference between the two is that a hip is at the top of
the hanging rafters, and a valley is at the bottom of the rafters hanging on it.

2.2 Professional site inspection
The inspection of older homes must be done to establish the presence of the following
materials
a. Asbestos - Asbestos is and should be avoided as a dangerous substance. But people with
asbestos contact do not always develop health problems. Many variables depend on the
danger of illness: how much asbestos is in the air. How often exposure occurs and how
long it takes. How much time has gone by since exposure began Whether the person has
lung or respiratory conditions and whether the person smokes tobacco?

b. Lead
c. Mercury
Other hazardous materials to be inspected include
a. Home appliances- from the picture, there is no appliances
b. The type of ceilings
c. Electrical wiring systems
d. Dumbed batteries
e. Type of paints
f. Electronics
g. Lighting components/ chokes/ballast and lamps
Specific hazardous material identification and testing methods must be followed, so be sure
to hire an experienced inspector or contractor specializing in hazardous material
identification and removal if you believe that hazardous materials may be present.
3. Determining the method to be used for demolition
The budget for the demolition is 1000 Australian dollars. This must cover actual tearing
down and all other demolition associated works. The chosen mode for the demolition is
Deconstruction + Demolition.
Reasons for choosing the method
 Combining deconstruction and demolition is the most highly recommended type of
demolition.
 This involves the act of first deconstructing the house by removing parts of the
reusable materials and saving them.
 Once all desired recyclable and reusable materials are collected, the remaining
structure is demolished and the remaining debris is removed.
 This is an excellent solution for those who want to be effective, accessible and
environmentally accountable for their demolition method.
Deconstruction will involve manual demolition process, after which the building will be teared
town with help of an excavator.
4. Obtain demolition permits
A person may not do a demolition unless a —(a) a demolition permit applies to demolition ; or,
(b) demolition is incidental to the renovation, alteration, extension, improvement or reparation of
a building or an adverse structure and construction permits for construction work are applicable ;
or (c) demolition can be done without a demolition permit under part 5 of building act 2011.
The following checklist will help to secure the permit for demolition
 Make sure demolition work meets the relevant building standards
