What you have to do This Assessment relates to the following PERFORMANCE CRITERIA, knowledge and skills Please type your answers in black font. (Calibri 12 point) Task 1 Demolition A demolition work plan should be prepared and approved before demolition work on any site can be commenced. Sample demolition work plans are available on the internet which you can access to see what sort of information is required in such a plan. Go to the information button on the OLS under assessment 2, for some sample sites. For this task you must refer to AS 2601 The Demolition of Structures, the Code of Practice for Demolition Work and other relevant documentation to answer questions relevant to the location plan and photographs provided for this project (see Plan and photographs for Task 1 under the information button on the OLS). A four storey building with ground floor commercial premises and residential units above is proposed for this site following the demolition of the existing retail premises and ‘shop top housing’ (residential above a commercial premises). 1. List the major safety issues for this demolition that are relevant to protecting: a. the general public, The General public must be protected from the following;  Failing objects due to demolition work  Loud noise  Dust pollution especially from hazardous building items such as asbestos  Sparks from welding and grinding  Heavy vehicle movements and machinery when arriving and leaving site b. adjoining buildings, Buildings must be protected from the following:  Damage to the foundations  Movement of the soil around the foundations of the adjoining buildings  Damage to the structure of the adjoining buildings  the selection of appropriate demolition techniques and methods should be adopted as this can minimise safety issues such as vibrations to the adjoining buildings and movement around the foundations 2 LA023652, Assessment 2, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 3, March 2020

c. site personnel, and  ensuring that all appropriate safety equipment is worn onsite such as safety helmets, eye protection, safety boots, gloves etc.  Ensure site safety is upkept for example trip hazards are removed, sharp edges are accounted for, safety nets, scaffolds etc.  Entrance and exit of the site are easily accessed in case of emergency with site maps put up around the site.  Falling hazards such as openings on elevated levels are accounted for and safety measures are taken into consideration such as signage, gates, scaffolds, barriers. Handrails etc d. the immediate environment.  pollution to the air caused by dust and chemicals while demolishing  pollution caused by foreign objects and chemicals that run into drains and water ways as well as footpaths and roads when water runs through the site 2. By referring to AS 2601, a. suggest and illustrate the details of the type(s) of hoarding and/or overhead protection that will be required, and The Australian standard 2601 section 1.5.1.5, states that a hoarding must be used to fence the perimeter of the demolition site. This is because the distance between the public area and the structure being demolished is not greater than twice the height of the structure. In this case the hoarding must be constructed out of a solid material to a minimum height of 1.8.(AS 2601 section 1.5.1.8) Overhead protection is also needed in this case to cover the footpath and the facing façade protected by heavy duty scaffolding. The overhead structure must consist of a horizontal platform of solid construction and vertical supports. b. indicate their location(s) on the plan.

3. Given the age of these buildings, what hazardous substances might be expected to be encountered in these buildings and what procedures will be followed to confirm their presence and to manage them as part of the demolition process? (include at least 2 probable materials) An investigation by an engineer has ascertained that the structures:  consist of suspended timber floor on strip and pad brick footings; cavity brick walls with brick parapets up to 1.5 metres above roof height; and timber- framed roofs with corrugated iron roofing: the second floor in the two-storey building is timber framed. Interior fittings include timber stairs and cabinetry. Windows are a mixture of timber and aluminium-framed panels  has been partially damaged by fire: this has only affected the single storey structure on the corner but some severe damage was observed to the ceiling/roof framing although no collapse of materials/structural elements has occurred  that apart from caution having to be taken with the damaged ceiling and roof in the corner building, the structural integrity of the remainder of the buildings is sound  although the above roof parapets are stable, appropriate bracing/stabilising temporary support will need to be provided to enable controlled and safe removal of these elements  the remaining elements of the buildings can be demolished using standard demolition practices It is proposed to maximise reuse/recycling of materials as much as possible. Two hazardous substances that we may come across are: 4 LA023652, Assessment 2, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 3, March 2020

 lead paint  asbestos The procedure to confirm their presence are as followed:  Consultant with a Hygienist to conduct a Hazardous Report to test the site for hazardous materials initially. The Hygienist report will also be able to assist with ways to treat and dispose of materials.  The paint should be tested before demolition starts. Lead testing kits are easily accessible for everyone to buy from hardware. They can be used to provide a quick and effective result as to whether there is lead present it the paint in and around the structure.  Consultation of workplace asbestos register should be done to identify if the substance is in fact asbestos before any work is done. There are a few ways that asbestos can be identified, and they include taking a sample to an asbestos lab, consulting a license asbestos assessor. The management of these substances should be done in accordance to the Australian standards and regulations. According to safe work Australia managing the risks associated with asbestos involves:  Identifying asbestos in the workplace and recording this in an asbestos register  Assessing the risk of exposure to airborne asbestos  Eliminating or minimising the risk associated with asbestos by implementing control measures  Reviewing control measures to make sure that they are effective. The best control measure for the demolition would be to remove the asbestos and to do so a license asbestos removalist must be consulted for jobs over10sqm. The Australian standards 4361.2 - guide to lead paint management. When a site has been identified to having lead paint it must be managed to prevent it becoming a health hazard. Safe work Australia suggest that certain Precautions should be taken when demolishing materials containing lead include:  minimising the generation of lead dust and fumes  cleaning work areas properly during and after work-wearing the appropriate personal protective equipment (PPE)  maintaining good personal hygiene 4. List and briefly describe the main work activities/requirements for carrying out the demolition described, covering the following aspects:(maximum 1 page) a. documentation required,  Construction certificate  Council Approval LA023652, Assessment 2, CPCCBC4011B, Edition number 4 5 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 3, March 2020

 Site Plans  Architectural Plans  Engineering Report  Surveyors Plans  Asbestos Report  SWMS  Notification to Neighbours  Copy of required licenses b. protection measures, and  Protecting trees  Using sandbags and erosion control methods around drains to stop debris from entering drains  Using sediment control fences along edges of site  Dust control measures by using water  Waste bins  Scaffold and safety nets to stop damage to adjoining buildings  Vibration monitoring  Scaffolding and hoarding to protect general public and workers  Traffic controls for vehicle movements c. sequence of demolition (include explanation using structural principles) (maximum 1 page).  Council approval is submitted along with letters to neighbors this will include the plans of what will be put in the place of the demolished structure.  Once demolition has been approved the nominated licensed contractor will be notified on a start date  Before demolition commences the builder will come and have hoarding, toilets, a site office if required installed, the builder will also display a builders board with his details and safety requirements.  Power, electricity gas and water will all be disconnected and temporary water, power poll will be installed.  The demolishment crew will arrive on site and diminish dwellings manually as the dwellings are so close, they look like they are touching, they will do this for what is possible to manually do and when it is safe to do plant will arrive on site to complete.  A licensed Asbestos team will arrive to safely remove from site, wearing correct PPE and using correct techniques to ensure that debris isn’t let into the air, an example of measurements they would take is using a hose to water down the debris in the air. 6 LA023652, Assessment 2, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 3, March 2020

8. For one of these further investigations compose an email to an industry professional requesting their opinion/recommendation/quote appropriate to the action to be taken. Clearly indicate to whom you are addressing your enquiry. To: Main Sewer plumbers Subject: 1 Hoffmann Road, Thurgoona, NSW 2640 Hi Scott, Thank you for your time on the phone earlier. As discussed, can we meet onsite this Friday at 7am so we can walk through the site to review the Sewer line location. During our discovery we believe that the sewer line appears to be closer to the building than initially expected. Attached is a copy of the original sewer diagram, plans along with all the other relevant documentation. Kind Regards Sarah Lloyd-Jones 9. Nominate a standard form of contract that could be used for this project. Include details of the publisher, and details regarding what types of projects it suits. AS 4300 Contract This type of contract is used in commercial construction. It is intended to be used in the following types of contracts:  design and construct  design development and construction, and  design, novate and construct Lump sum contract which include the following components: • Lump sum price - the contractor is obliged to carry out the project for a fixed price. • Fixed timeframe - the contractor ensures the works will be completed by an agreed date (known as the ‘date for practical completion’). Liquidated damages may apply in the event of a delay. • Practical completion - the point at which the construction project can be used \and occupied before all works (such as minor’s works) are actually completed. 10 LA023652, Assessment 2, CPCCBC4011B, Edition number 4 © New South Wales Technical and Further Education Commission, 2020 (TAFE NSW), Version 3, March 2020

• Design obligations - the contract requires the principal to provide the contractor with a design brief. The principal may also be required to provide a ‘Preliminary Design’ where the principal chooses a ‘design, development and construct’, or ‘design, novate and construct’ contract. • Variations - the contract provides a process for addressing variations between the design and the actual construction. • Extensions of time - the contractor is able to claim extensions of time to the date for practical completion if it is delayed by an event listed at clause 35.5 (which includes delay caused by the principal). • Latent Conditions - the contractor may claim an extension of time and additional costs if it encounters a latent condition. A latent condition is a physical condition on or near the site that could not reasonably have been anticipated by a competent contractor at the time of tendering. • Provisional sums where the design of part of the works is not sufficiently developed, a provisional sum may be provided. A provisional sum is an allowance for a specific element of the works that is not yet defined in enough detail to accurately price.
