75
What is trench or strip footing foundation, and what are they used for?
Shallow foundation that avoids bricklaying below ground by filling trench with concrete. Useful method used in residential and retail buildings as quick and easy. Only issue is that it must be used in areas where soil has good drainage or water can pond in the foundations, weakening them over time.
76
What is a raft foundation and when are they used?
Shallow, slab foundation reinforced by concrete slabs of uniform thickness. Typically used to spread the weight of a building over a larger area so typically used in for industrial/warehouse applications, the reinforced concrete literally sits on top of the soil like a raft. Not good to use on clay soils as the clay moves and cracks the shallow slabs.
77
What is a piled foundation and when are they used?
Long, slender reinforced concrete cylinders or beams used for large structures. Embedded upright in the ground and used when the soil is weaker as the piles can be buried very deep - good for supporting taller buildings like office blocks
78
What is a pad foundation?
Generally shallow, pads support single-point loads like columns and frames. The pad extends beyond the building to provide greater strength.
79
What is the typical specification of new retail units?
Steel or concrete frame, services capped off, concrete floor, shell condition with no shop front ready for retailers own fit out
80
What are the current institutional specifications for industrial property?

81
What would you do if you identified a building defect during an inspection?
Take photo, try to establish cause, inform client, recommend specialist advice from building surveyor or structural engineer
82
What are common defects in period residential, office and shop buildings?
