Examples of Common Construction Planning Equipment and Methods
To illustrate how to apply the evaluation and selection criteria, let us consider some examples of common construction planning equipment and methods for different types of construction tasks. Note that these are not exhaustive lists, but rather indicative examples that may vary depending on the specific project context.
Excavation Methods
Some common excavation methods are:
Open Excavation: This method involves digging a trench or a pit on the ground surface using excavators, loaders, trucks, etc. It is suitable for shallow depths, soft soils, low groundwater levels, etc. It is relatively simple, fast, cheap, but may cause surface disturbance, noise, dust, etc.
Cut-and-Cover Excavation: This method involves digging a trench on the ground surface using open excavation techniques, then covering it with a temporary or permanent structure such as a roof or a slab. It is suitable for medium depths, urban areas, utility crossings, etc. It is relatively complex, slow, expensive, but may provide better protection, stability, and aesthetics.
Tunneling Excavation: This method involves digging a tunnel below the ground surface using tunnel boring machines (TBMs), drill-and-blast techniques, shield machines, etc. It is suitable for deep depths, hard rocks, high groundwater levels, etc. It is relatively complicated, slow, expensive, but may avoid surface disruption, traffic interference, and environmental impact.
Foundation Methods
Some common foundation methods are:
Shallow Foundation: This method involves placing a foundation element such as a footing, a mat, or a slab directly on or near the ground surface. It is suitable for light loads, stable soils, low water tables, etc. It is relatively simple, fast, cheap, but may be prone to settlement, differential movement, and frost heave.
Deep Foundation: This method involves placing a foundation element such as a pile, a caisson, or a pier deep into the ground. It is suitable for heavy loads, weak soils, high water tables, etc. It is relatively complex, slow, expensive, but may provide better bearing capacity, stability, and resistance to lateral forces.
Raft Foundation: This method involves placing a large and thick foundation slab that covers the entire area of the structure and distributes the load evenly over the soil. It is suitable for large structures, variable soils, high seismic zones, etc. It is relatively simple, fast, moderate in cost, but may require extensive excavation and reinforcement.
Formwork Methods
Some common formwork methods are:
Timber Formwork: This method involves using wood
