Construction

Construction BASIX * The Building Sustainability Index (BASIX) * BASIX is implemented under the Environmental Planning and Assessment ACT * BASIX aim to reduce water and energy consumption in homes across NSW Construction basics * ACT- general laws * BCA- building code Australia * NCC- National Construction Code * Standards is the bare minimum e.g. 40mm concrete cover * SWMS- Safe Work Method Statement (steps to complete talks safetly OH&S * WHS: Workplace Health and Safety * Risk: The probability that a person will be harmed or experience an adverse health effect if exposed to a hazard. * Hazard: Anything that has the potential to harm a person. * Hazard Categories: * Acute Hazard: A hazard where short term exposure causes an injury or sickness (Burns, Cuts, etc.) * Chronic Hazard: A hazard where long term exposure causes an injury or illness (Respiratory, Cancer, etc.) * Correct Lifting technique: 1. Size up load 2. Position Feet 3. Obtain good grip 4. Knees bent and back straight 5. Head up and Chin in 6. Keep arms in * Main Types of Hazards : * Physical (Noise, Vibration, Manual Labor) * Chemical (Gas, Vapor, Dust, Fumes) * Biological (Insect/Animals, Fungi) * Risk Control: 7. Elimination 8. Substitution 9. Isolation 10. Engineering Controls 11. Admin Controls 12. PPE * PPE (Personal Protective Equipment): Last line of defense * WMS (Work Method Statement): Contains the steps to perform a task properly and safely (it usually contains the potential risks of the task that has been assessed and categorized) * MSDS (Material Safety Data Sheet) Contains composition and name of the chemical and also gives safe use and first aid. Fire safety * Fire requires heat fuel and oxygen * Class A: combustible solids e.g. Paper, plastics, clothing * Class B: Flammable liquids e.g. Fuel, Paint, Thinners * Class C: Flammable gases e.g. LPG, Methane, Butane * Class E: Electrical e.g. Switchboard overload, electronic motors Measurements, Calculations and Drawings * 50 bricks in 1m2 * 10% wastage factor: multiply answer by 1.1 * Pictorial drawings give a visual representation of the final product * Two types of pictorial: Isometric projection and Perspective view * Orthographic Drawing: A working drawing that consists of 3 related views and includes details like scale and dimension. * Most Common Drawings builders use (Working Drawings) 1. Floor Plans (1:100) 2. Site Plans (1:200) 3. Section (1:10) 4. Scale 5. Elevation (1:100) * Title Block: Contains owners name, lot number, street name, suburbs and scale etc. * Specification: A precise list of all construction and finishing organized by trade. Leveling * Leveling: The determination and representation of elevation points from an unknown datum. Measuring the differences in elevation. * Level Line: A line that is parallel to the surface of still water. * Plumb: Any vertical line that would line up with the center of the earth. This can be determined with a Plumb bob (weight attached to a string). * Datum: Any known point which a level line can be transferred to another position * String Line (Brick layer line) strong taught lines that give an accurate level. Building Terms * DAR: dressed all round * CCA: coper, chromium, arsenic salts * DOS: dressed one side * D1S1E: dressed one side and one edge Manufactured Boards * Particle boards (chip board) * Fibreboard (MDF) * Hardboard (Masonite) * Plywood Safety signs Mandatory | | Must do signs | Prohibited | | Don’t do signs | Hazard | | Warning | Danger | | Warning (more serious) | Emergency | | First aid, Exits etc | Specialist Trade requires Certificate IV * Crane Operator * Building Manager * Heritage Restoring Building Safety standards Is a set of rules that specify the minimum acceptable level of safety for constructed objects. * As 1670 (fire detection) * As 1720 Timber grades * AS 1684 (TIMBER FRAME CONSTRUCTION) Brick and Block Tools… Refer to book Communication * Formal meetings: UNION meeting, OHS and Induction * Informal meetings: tools box meeting
