Construction Design Principles - Week 5

An investigation to acquire information about a piece of ground undertaken by reviewing existing records from the office, is known as what type of site investigation?

• Geotechnical investigation

• Walk-over survey

• Desk study

Visiting a site to enable the surveyor to match the information from the desk study to what they see in the plot (physically visiting the site), is known as what type of site investigation?

• Geotechnical investigation

• Walk-over survey

• Desk Study

The substructure refers to everything above the ground

• True

• False

Any ground that has been artificially made from material placed from previous works, for example layers of stone compacted and laid to form a level surface and is most likely to be contaminated. This type of soil is known as what?

• Organic soil

• Fill/Made Ground

• Non-Cohesive Soil

Generally the strongest material with good bearing capacity. Some rocks will behave more like weak soils especially when the moisture content is high. This type of soil is known as what?

• Cohesive Soil

• Coarse Grained Soil

• Rock

Static loads are assumed to be constant in nature and consist of which two types of loads?

• Dead loads

• Seismic loads

• Live loads

• Dynamic Loads

This type of force is as a result of sudden movements in the earth’s crust. They are multidirectional in nature and propagated in the form of waves. These cause the earth’s surface and any buildings resting on it to vibrate because of the tendency of a building’s mass to remain at rest.

• Wind loads

• Live loads

• Seismic Forces

This type of foundation is most commonly used under point loads such as columns. It can be used under ground beams to transfer continuous loads.

• Strip foundation

• Pile foundation

• Raft foundation

• Pad foundation

This type of foundation is used where building loads are high or ground conditions poor,  where differential movements are expected and where subsidence is expected due to mining.

• Strip foundation

• Pile foundation

• Raft foundation

• Pad foundation
