Answer 4

Stations

Question 5

In a mass diagram of earthwork the ordinate (y-axis) represents?

Answer 5

The cumulative corrected algebraic sums of volumes of earthwork / cubic yards (excavation and embankment)

Question 6

on AOA networks, what does TF mean and how is it calculated

Answer 6

TOTAL FLOAT, TF = LF - EF
(TOTAL FLOAT EQUALS LATE FINISH MINUS EARLY FINISH)

Question 7

on AOA networks, what does LF, EF, mean

Answer 7

LATE FINISH AND EARLY FINISH

Question 8

on AOA networks, what does LS, ES mean

Answer 8

LATE START AND EARLY START

Question 9

How do you calculate the Early finish on a AOA?

Answer 9

Early start + Duration

Question 10

what is SPI, and what does it mean if it is equal to a number greater than 1 (>1)

Answer 10

schedule performance index, project is ahead of schedule

Question 11

Define Risk

Answer 11

is an uncertain condition of event that if it occurs has at least an effect on project objective - scope, schedule, cost, quality

Question 12

Define Free Float

Answer 12

is the amount of time that an activity may be delayed with delaying the early start of the following activities

critical path is delayed, the project as a whole will be delayed

Question 17

Question 18

What is a “neat line”

Answer 18

A line that defines the limits of excavation, the contractors are not paid beyond this line.

Question 19

What is SPI and what does it mean when it is greater than 1

Answer 19

Schedule Performance Index - *****

when SPI is greater than 1 the project is AHEAD of schedule

Question 20

how do you solve for the breakeven time period for an investment

Answer 20

payback/ breakeven = (cost of investment)

Question 21

Answer 21

FALSE

Question 22

Name three methods for calculating earth work quanities

Answer 22

End Area Method, Coordinate methods, Borrow Grid Methods

Question 23

Name three things to consider when building a new storm drain line and a detention basin

Answer 23

1. The cut and fill necessary for the basin
   2.The existing underground utilities
2. Storm water pollution prevention plan
