DEMOLITION METHODOLOGY

All works are to be undertaken in accordance with the following regulations;

• Work Health & Safety Act 2011; • Work Health & Safety Regulation 2011; • Safe Work Australia (2011) – How to Safely Remove Asbestos; • Safe Work Australia (2011) – How to Manage and Control Asbestos in the Workplace; • NOHSC Code of Practice for the Safe Removal of Asbestos 2002 (2005);

• Australian Standard 2601 (2001) – Demolition of Structures; • All relevant DEC, EPA and WorkCover NSW guidelines; • City of Ryde’s DA/CDC and Asbestos Policy

SITE PREPARATION

• Make sure 1.8 metre high safety fencing has been installed to property where works are to be done. • Make sure a minimum of two comprehensive warning/safety signs have been displayed on fencing and

all other entrances to effected area. • Make sure that all services; water, gas, electricity have been disconnected prior to any work commencing

on site. INDUCTIONS/SITE TRAINING

• All site personnel are to be inducted into the relevant work method statements. • Make sure that the following documentation is sighted, read, understood and signed by all staff prior to

commencement on site; - Work Cover Notification Form - Demolition Work Plan - Safe Work Method Statement

• Once all of the above have been completed the designated competent person shall conduct a toolbox talk with all staff on site outlining the works to be carried out each day.

• All Personal Protection Equipment (PPE) will be handed out to each employee at the beginning of each day.

Page 4 of 23 WORK PROCEDURE – ASBESTOS REMOVAL (IF IDENTIFIED)

• All asbestos will be removed in accordance with the abovementioned regulations and NOHSC: 2002

(2005). • The truck or skip bin will be lined with 200 micron thick plastic so it is ready to be loaded with asbestos

material. • All material containing asbestos will be sprayed down with a PVA glue and water mix to encapsulate any

fibres that may become airborne during the removal process. • All fastening screws (will be unscrewed) or nails (will be center punched) so as to loosen asbestos

sheeting. • All asbestos material will then be removed by hand and placed into either a plastic lined truck or asbestos

bags for removal from site. • All surfaces in contact with asbestos cement material will be de-nailed, vacuumed (using approved

vacuum), and sprayed with a PVA encapsulent. • Any works over 1.8m in height shall have some form of fall arrest system put in place (i.e.; enertia

reel/harness) this will be set up by a qualified person on site. Staff will be briefed in required “hook on” “hook off” procedure.

• This process will continue until all material containing asbestos has been removed. • The truck will then have its load taped up so it is air tight and be carted to a licensed landfill for disposal.

WORK PROCEDURE – HAND DEMOLITION

• The demolition on site will be carried out in accordance with AS 2601 (2001). • Materials handling will be by means manual labour (pinch bars, jackhammers, sledge hammers) loaded

into trucks (bogie tippers and semi trailers). The debris will be carted offsite to an approved waste facility or recycling centre.

• At the discretion of either site instructions from demolition supervisor or the onsite competent person, any parts of the structure that may cause damage to fences or neighbouring properties during the mechanical demolition process shall be isolated by hand to reduce or remove the risk of possible damage.

• Any works over 1.8m in height shall have some form of fall arrest system put in place (i.e.; enertia reel/harness) this will be set up by a qualified person on site. Staff will be briefed in required “hook on” “hook off” procedure.

• Any part of the timber framed walls requiring hand isolation will be cut down with chainsaws or pried apart with crowbars, while working off internal floors or scaffolding. Any part of the brick walls requiring hand isolation will be hammered down by staff using club hammers or sledge hammers. All staff will work off internal floors with chainsaws or pried apart with crowbars, while working off internal floors or external scaffolding.

• All material will be stockpiled in-situ or wheel barrowed to stockpile, drop zone or placed directly into truck or skip bin.

• Tipping dockets to be kept and forwarded to Main Contractor WORK PROCEDURE – MECHANICAL DEMOLITION

• The demolition on site will be carried out in accordance with AS 2601 (2001). • At the discretion of either site instructions from demolition supervisor or the onsite competent person,

any parts of the structure that may cause damage to fences or neighbouring properties during the mechanical demolition process shall be isolated by hand to reduce or remove the risk of possible damage.

Page 5 of 23 • Any works over 1.8m in height shall have some form of fall arrest system put in place (i.e.; enertia

reel/harness). • The building structure will then be demolished by an excavator and separated by use of grabs into

stockpiles for loading out. • Staff on site shall hose the structure as it is being demolished to reduce airborne dust leaving site. • The material will then be loaded by excavator into trucks for disposal (all loads to be tarped prior to

leaving site). • All debris will be carted to a licensed landfill or recycling yard • Tipping dockets to be kept and forwarded to Main Contractor

WORK PROCEDURE – ROOF WORK (‘HOOK’ & ‘UNHOOK’ PROCEDURE)

This procedure applies on all work sites where there is a risk of persons falling 1.8 meters or greater, or where persons are working within 2 meters of a live edge or brittle surface, (i.e. enertia reels).

• Inspect ladder for damages. If damaged discontinue use of ladder and notify management immediately,

if in good working order proceed to next step. • Place ladder on level ground and extend ladder so it passes gutter/fascia by at least 1 metre. The ladder

should be set up at a ratio of 4:1 meaning for every four metres in height it should be one metre away from its vertical point of origin.

• A suitably qualified person shall then secure the ladder to the structure by use of rope or strap to either a truss or joist.

• A suitable qualified person with then put on his/her safety harness and take an enertia reel up the ladder and secure it to the roof truss within reach of the ladder. This work will be performed while remaining on the ladder.

• After securing themselves to the enertia reel, they will grab the required amount of additional enertia reels and proceed onto the roof where they will fit them to the peak of the roof using the straps and carabeners attached to the reels.

• They will then ‘hook’ themselves to the new enertia reel. Once this is done they can remove the original hook from the enertia reel adjacent to the ladder.

• The suitable qualified person will then grab the remaining unused enertia reel hooks and proceed to the ladder.

• All additional staff will then fit their harness and proceed up the ladder. Before leaving the ladder, the supervisor will ‘hook’ them onto their reel so they can proceed onto the roof to carry out required task.

• Anytime any staff need to come down from the roof they must stay ‘hooked’ onto their enertia until they are safely onto the ladder. Once on the ladder they will ‘unhook’ their enertia reel and ‘hook’ it onto the ladder or roof truss adjacent to the ladder so it is within reach of the ladder if they must return to the roof.

• Once work on roof is completed and remaining staff has ‘unhooked’ while on the ladder and proceeded to the ground, the suitably qualified person will then remove the enertia reels in a reverse order to how they were set up.

EMERGENCY RESCUE PLAN

Where a fall restraint or fall-arrest system is used, provisions shall be made to enable the safe rescue of a person who falls. These provisions should include: • An effective rescue plan for that site is developed prior to work commencing with a toolbox talk • Personnel are appropriately trained in height safety and first aid and

Page 6 of 23 • Appropriate rescue equipment available

The rescue plan should enable the person to be removed from the suspended position as quickly as possible to prevent the fallen person developing suspension trauma.

Emergency services CALL 000 should be contacted immediately and supervisor notified.

DAMAGE AND STRUCTURAL INTEGRITY No demolition activity shall cause damage to or adversely affect the structural integrity of adjoining buildings.

SEQUENCE OF DEMOLITION Unless otherwise permitted by the regulatory authority structures shall be demolished in reverse order to that of their construction. The order or demolition for buildings shall be progressive, storey by storey having proper regard to the type of construction.

REMOVAL OF DEMOLISHED MATERIALS Unless otherwise permitted by the regulatory authority demolished material shall not be allowed to fall freely outside the structure unless it is confined within a chute or similar enclosure. Demolished material shall not be allowed to fall freely within a structure unless it is confined within a shaft or similar enclosure which is clear of obstructions to objects falling freely. Demolished materials shall be removed progressively from the site at any time, shall not be allowed to accumulate to the extent that it presents a hazard to the public or site personnel.

CUTTING OR LOWERING OF LARGE MEMBERS If necessary to suit the capacity of the available hoisting equipment large members shall be cut into smaller sized portions before lowering. Whole or large portions of members shall be lowered in a controlled manner so that there is no likelihood of them falling freely. Wherever possible a crane or similar lifting device shall be used to support beams or columns while they are being separated from the remainder of the structure.

MANUAL DEMOLITION Personnel shall be permitted to work only from safe and serviceable work platforms and unless attached to an approved fall arrest system shall not be permitted to work from the top of a wall or partition being demolished. Where concrete members are being demolished manually the reinforcement shall not be cut while breaking out of the concrete is in progress.

Hazardous materials including asbestos shall be removed only by competent persons in accordance with the requirements of the regulatory authority and the relevant standards.

DUST CONTROL The techniques adopted for stripping out for demolition shall minimise the release of dust into the atmosphere. Before the commencement of stripping or demolition in an area of a structure any existing accumulations of dust in that area should be collected, placed into suitable containers and removed. Selection of an appropriate collection technique such as vacuuming or hosing down shall take due account of the nature of dust and type of hazard it presents (e.g. explosive, respiratory). Dust generated during stripping or during breaking of the building fabric to removable sized pieces shall be kept damp until it is removed from the site or can otherwise be contained. The use of excess water for this purpose shall be avoided.

NOISE CONTROL Noise shall be minimized as far as predictable by the selection of appropriate methods and equipment and by the use of silencing devised where predictable.

PROTECTION OF PUBLIC ROADS Precautions shall be taken in accordance with the requirements of the regulatory authority to minimize the spreading of mud and debris by vehicles leaving the site.

OH&S POLICY A detailed OH&S Policy in compliance with AS4801 will be provided by the Contractor prior to work commencement. A detailed Site Safety Plan will be prepared for the specific project.

ENVIRONMENTAL IMPACT STATEMENT TEMPORARY ENVIRONMENTAL IMPACT

In most cases there are only two to three aspects of temporary environmental impacts from on a property during demolition works, these are;

1. Dust / Airborne Nuisance: to keep this to a minimum, the hosing of water during external demolition

and loading out of material keeps this under control.

2. Water / Sediment Run Off: to control this water on site is used only to dampen debris rather than saturate to reduce water runoff.

3. Asbestos removal; containment of loose fibres.

PERMANENT ENVIRONMENTAL IMPACT

Due to the methods used by the Contractor throughout the demolition process there is no permanent environmental impact.

SOIL & WATER MANAGEMENT PLAN

Soil and Water Management will be carried out by the Main Contractor in accordance with Council approved sediment and erosion control plans.
