Study Notes
Earthwork Equipment
- Hydraulic Clamshell used for excavating foundation pits, deep confined spaces, and loose soils.
- Dozers primary function is to push, dig, excavate, and level materials, also used for clearing trees and vegetation, can act as towing tractors.
- Roller Compactor compacts earth and other materials.
- Scraper cuts, collects, and moves large quantities of spoil across construction sites, also used for site leveling, loading, and hauling.
- Dumper best suited for transporting large amounts of material over distances both on and off site.
- Grader primarily used to level and flatten soil surfaces, removing unnecessary layers of soil, dozers are typically used for rough grading while graders are used for finishing.
Earthwork Selection Criteria
- Quantities of Material: Consider the volume of material to be excavated.
- Soil Type and Condition: Impact the type of equipment required.
- Weather Conditions: Poor weather can affect equipment performance and safety.
- Excavation Speed: The timeline for excavation will influence equipment choice.
- Excavation Depth: Depending on the depth, certain equipment may be more suitable.
- Material Disposal Method: How the excavated material is disposed of impacts the process.
Types of Earthwork Equipment
- Backhoe: Also known as a rear actor, performs digging holes and trenches, excavation, landscaping, breaking up asphalt and concrete, loading and unloading materials, and leveling uneven ground.
- Front Shovel: Excavates various soil types, digs and loads earth or fragmented rock, depth limitations.
- Dragline: Best suited for bulk excavation in loose or waterlogged soils below its own track level.
- Hydraulic Clamshell: See above
- Dozers: See above
- Roller Compactor: See above
- Scraper: See above
- Dumper: See above
- Grader: See above
Factors on Selection
- Labour Consideration: Trained labor availability is key.
- Safety Requirements: Site safety is essential.
- Environmental Considerations: Carbon emissions, noise, vibration, and dust impact the environment.
- Authority Requirements: Adherence to relevant statutory standards, regulations, and guidelines is crucial.
Uniform Building By-Laws
-
Part II (Submission of Plans for Approval) Temporary permits are required for:
- Erection of builders' working sheds or stores
- Depositing building materials on streets
- Erection of scaffolding
- Hoarding on streets
- Part IV (Temporary Works in Connection With Building Operations) Commencement of building operation is regulated by By-Laws 48.
