What is the difference between a load-bearing wall and a non-load-bearing wall?

A load-bearing wall supports the weight of the building and its contents, while a non-load-bearing wall does not.

A load-bearing wall is made of a strong material, such as brick or concrete, while a non-load-bearing wall is made of a weaker material, such as drywall.

A load-bearing wall is typically thicker than a non-load-bearing wall.

A load-bearing wall is typically located on the exterior of the building, while a non-load-bearing wall is typically located on the interior of the building.

To manage the risks associated with construction projects.

To protect the health and safety of workers and the public.

18.

What is the difference between a variation and a claim?

A variation is a change to the scope of work that is agreed upon by both the contractor and the owner. A claim is a dispute between the contractor and the owner about the scope of work, the schedule, or the budget.

A variation is a change to the scope of work that is initiated by the owner, while a claim is a change to the scope of work that is initiated by the contractor.

A variation is a change to the scope of work that is agreed upon in writing, while a claim is a change to the scope of work that is not agreed upon in writing.

All of the above.

19.

What are the two main forces that bridges must resist?

Gravity and wind.

Gravity and traffic.

Traffic and wind.

Gravity, traffic, and wind.

20.

What is the difference between a rolled steel section and a fabricated steel section?

A rolled steel section is manufactured by passing a steel billet through a series of rollers to shape it into a desired profile, while a fabricated steel section is manufactured by welding together multiple steel plates.

A rolled steel section is stronger than a fabricated steel section.

A rolled steel section is more durable than a fabricated steel section.

A rolled steel section is more expensive than a fabricated steel section.

21.

What is the main difference between a prestressed concrete member and a non-prestressed concrete member?

A prestressed concrete member has internal forces that are applied to the concrete before the application of external loads, while a non-prestressed concrete member does not.

A prestressed concrete member is stronger than a non-prestressed concrete member.

A prestressed concrete member is more durable than a non-prestressed concrete member.

A prestressed concrete member is more expensive than a non-prestressed concrete member.
