Gravity and traffic.

Traffic and wind.

Gravity, traffic, and wind.

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.

To reduce the cracking of concrete.

To improve the ductility of concrete.

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.

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.
