A

Welded Wire Mesh

38
Q

How do you find Labor Costs?

A

LC = Quantity Takeoff x Appropriate Productivity Rate

39
Q

What are the steps to the procedure to estimate concrete on a project? (4)

A

1) Review specs and list out requirements for each area
2) Review drawings and compare with specs
3) List each of the concrete items required on the project
4) Determine quantities from drawings

40
Q

Where do the Footings extend out from? And what is the length of the Footings in comparison to the wall length?

A

1) Footings extend out from the foundation wall

2) Footings length is greater than wall length

41
Q

When estimating footings, columns, beams, and girders, how is their volume determined?

A

Volume is determined by taking the linear footage of each item times its cross-sectional area.

42
Q

When estimating footings for buildings with irregular shapes and jogs, what must the estimator be careful to include only once?

A

the corners

43
Q

46
Q

This is created by placing topsoil over the rough grade.

A

Finish Grade

47
Q

60
Q

Excavated material that is uncompacted and is usually used as the fill on projects.

A

The compression of soil being compacted into a smaller form than when it was loose. This is expressed as a percentage of the undisturbed original or bank volume.

A

Shrinkage

62
Q

When __________ materials are placed and compacted on a project. It will often occupy less volume than in its Bank condition. This reduction is referred to as shrinkage.

A
