NECA Project Management & Estimating 5

Question 1

Which project delivery method gives the electrical contractor the most control over design decisions affecting installation?

Accepted Answer

Design-Build (DB)

Answer

In Design-Build, the contractor is responsible for both design and construction, giving maximum influence over design decisions that affect installability and cost.

Question 2

An electrical subcontractor is owed $150,000 by the general contractor who has gone insolvent. Which document provides the sub the best legal protection to recover payment from the owner?

Accepted Answer

Notice of intent to lien / mechanic's lien

Answer

A mechanic's lien encumbers the owner's property, giving the subcontractor legal recourse to recover unpaid amounts from the property itself.

Question 3

When using the 'extension method' to price labor in an electrical estimate, what three components are multiplied together?

Accepted Answer

Labor units, quantity, and burdened labor rate

Answer

The extension method multiplies the labor unit (hours per unit) × quantity × burdened hourly rate to arrive at the total labor cost.

Question 4

What is the significance of the 'critical path' in CPM scheduling for an electrical project?

Accepted Answer

It is the longest sequence of dependent activities that determines the minimum project duration

Answer

The critical path is the longest chain of dependent activities; any delay to a critical path activity directly delays project completion.

Question 5

A project has a Budget at Completion (BAC) of $1,000,000, Earned Value (EV) of $400,000, and Actual Cost (AC) of $500,000. What is the Cost Performance Index (CPI)?

Accepted Answer

0.80

Answer

CPI = EV ÷ AC = $400,000 ÷ $500,000 = 0.80, indicating the project is spending $1.25 for every $1.00 of work accomplished.
