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 motorsMeasurements, 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 edgeManufactured Boards
* Particle boards (chip board)
* Fibreboard (MDF)
* Hardboard (Masonite)
* Plywood
