Construction Management Flashcards

What is the Critical Path Method (CPM) in construction project scheduling?

Answer: A scheduling technique that identifies the longest sequence of dependent activities determining minimum project duration

CPM identifies the critical path — the longest chain of dependent activities through the project network. Any delay on critical activities directly delays the project completion date.

In construction project management, 'float' or 'slack' refers to:

Answer: The amount of time an activity can be delayed without affecting the project completion date

Total float is the maximum delay of an activity without delaying project completion. Activities on the critical path have zero float. Float is essential for resource leveling and schedule optimization.

What is Earned Value Management (EVM) used for in construction?

Answer: Integrating scope, schedule, and cost to measure project performance and forecast completion

EVM integrates three dimensions (scope, schedule, cost) using metrics like CPI (Cost Performance Index) and SPI (Schedule Performance Index) to objectively assess project health and forecast outcomes.

Hot weather concreting in Saudi Arabia requires special precautions because high temperatures cause:

Answer: Rapid moisture loss, accelerated setting, reduced strength, and increased cracking risk

Temperatures above 35°C accelerate hydration, increase water demand, reduce workability, cause rapid slump loss, and promote plastic shrinkage cracking. SBC and ACI 305 prescribe precautions for hot weather concreting.

What is the purpose of a construction method statement?

Answer: To describe how specific work will be safely and effectively carried out on site

A method statement details the step-by-step process for carrying out specific construction activities, including equipment, materials, sequence, safety measures, and quality control procedures.

In Saudi construction, a performance bond typically guarantees:

Answer: The contractor will complete the work in accordance with the contract terms

A performance bond (typically 5-10% of contract value in Saudi Arabia) provides financial guarantee that the contractor will fulfill all contract obligations. If the contractor defaults, the surety compensates the owner.
