A

Concrete.

31
Q
  1. Type of concrete?
A

Type 1 - it is normal Portland cement and is used in most residential construction.
Type 2 - it is used for structures in water or soil containing moderate amounts of sulfate or when heat buildup is a concern.
Type 3 - It is used when high early strength is desired. It is not common in single-family residential construction.
Type 4 - It is low heat Portland cement and is used when the amount and rate of heat generation must be kept to a minimum. It is not common in single-family residential construction.
Type 5 - It is sulfite resistant Portland cement and is used when the water or soil is high in alkali.

32
Q

A

Damp proofing.

33
Q
  1. Conditions requiring a set of plans and specifications created by a registered (licensed) design professional and beyond the prescriptive requirements of the IRC.
A

Design required.

34
Q
  1. The finished ground level adjoining the building at all exterior walls?
A

Grade.

Q
  1. Load produced by use and occupancy of the building and not including wind, snow, rain, earthquake, flood, or dead loads?
A

Live loads.
