Deck 10: Pricing Excavation and Backfill

Question 1

Changes in productivity should be dealt with in the same component of the unit price as wage rate changes for the most accuracy.

Answer 1

False

Question 2

Pit and sump excavation is mostly performed using ____.

A)shovels
B)front-end loaders
C)backhoes
D)excavators

Answer 2

C

Question 3

Backfill material that is compacted will be more dense than before it is compacted so, to fill a certain volume with compacted material, a larger volume of loose material will be required.

Answer 3

True

Question 4

The ____ is an allowance for the extra material required to fill volumes with compacted material rather than loose material.

A)growth factor
B)stability factor
C)compaction factor
D)compression factor

Question 5

A large-size excavation company is generally equipped to effectively perform all types of excavation work.

Question 6

Whenever it is possible, the contractor will use the material excavated at the site for backfill requirements.

Question 7

Generally a large project causes crews and equipment to have low rates of productivity.

Question 8

____ are used when loads that are oversize are transported.

A)Lead trucks
B)Beacon trucks
C)Scout trucks
D)Flag trucks

Question 9

The cost of transporting equipment includes the cost of loading, unloading, and trucking requirements.

Question 10

Material prices for backfill have three main components.

Question 11

Tracking productivity rates separately from prices also has the advantage of "____"-the same productivity rates can be used in different localities, only the wage rates have to be adjusted to reflect pay rates that differ from place to place.

A)transportability
B)availability
C)transparency
D)efficiency

Question 12

Transportation of major items of equipment-backhoes, bulldozers, loaders, power shovels, and the like-is better priced on an item- by- item basis.

Question 13

Excavation contractors tend to concentrate on a single specific type of construction.

Question 14

The cost of transporting minor items of equipment such as plate compactors, small rollers, bobcats, and small tractors to and from the site is priced on the General Expense Sheet under the item "____."

A)Loading and Material Handling
B)Trucking and Material Handling
C)Trucking and Material Storage
D)Loading and Trucking

A)Site cut-and-fill operations
B)Basement-type excavations
C)Trench excavations
D)Pit and sump excavations

Question 16

When soil or gravel is excavated, the resulting material is less dense than it was in the ground before it was disturbed. This same material now occupies more volume, a concept called the ____.

A)compaction factor
B)swell factor
C)stability factor
D)growth factor

Question 17

The equipment used in cut-and-fill operations depends mostly on the ____ of the project.

A)scale
B)region
C)code requirements
D)timeline

Question 18

All of the following are considered job factors that impact the productivity of excavation and backfilling operations EXCEPT ________.

A)type of material excavated or backfilled
B)access to or around site
C)project size and complexity
D)quality of job labor

Question 19

In order to determine the labor price per unit of excavation work, four elements have to be considered: 1)the number of workers that comprise the work and crew; 2)the wage rates of the trades involved; 3)the probable productivity rate of the crew or the equipment they are operating; and 4)the productivity time factor.

Question 20

Perhaps the most important job factors that must be established before an estimate of any trade can be prepared are the ____ and equipment prices prevailing at the location of the project under consideration.

A)trade labor times
B)trade lead times
C)trade qualifications
D)trade wage rates
