CCM Cost and Time Management 5

Question 1

A construction manager notices activities on the critical path have zero total float. A non-critical activity has 5 days of total float consumed. What is the impact?

Accepted Answer

The activity's float buffer is reduced but project end date is unaffected unless all float is consumed

Answer

Consuming total float reduces the buffer available before the activity delays the project; the end date is only affected if all float is exhausted.

Question 2

Which change control process step ensures that a proposed scope change's cost and schedule impacts are evaluated before approval?

Accepted Answer

Impact analysis

Answer

Impact analysis evaluates the cost, schedule, quality, and risk effects of a proposed change before the change control board decides to approve or reject it.

Question 3

A project uses unit price contracts for earthwork. Actual quantities exceed bid quantities by 20%. What is the financial impact on the owner?

Accepted Answer

Owner pays the additional quantity at the contracted unit price

Answer

Unit price contracts require the owner to pay for actual quantities used at the agreed unit price, so a quantity overrun increases owner cost proportionally.

Question 4

What is the significance of a 'zero float' activity that is NOT on the original critical path?

Accepted Answer

It has become a new critical path activity due to schedule changes

Answer

When a non-critical activity's float is consumed to zero, it joins the critical path, meaning any further delay will push the project end date.

Question 5

Which estimating approach involves pricing each individual work item from quantity takeoffs and summing all components?

Accepted Answer

Bottom-up estimating

Answer

Bottom-up estimating builds a detailed estimate by pricing individual work packages or activities and rolling them up to a total project cost.
