Project Planning & Scheduling Flashcards

During the planning phase of a demolition project, what is the PRIMARY purpose of a pre-demolition survey?

Answer: To identify hazardous materials, structural elements, and site conditions

A pre-demolition survey identifies hazardous materials, structural vulnerabilities, and site conditions that affect safety planning and sequencing.

Which scheduling method shows task dependencies using arrows and nodes to represent activities and their relationships?

Answer: PERT/CPM network diagram

PERT/CPM network diagrams use arrows and nodes to represent activities and their logical dependencies, identifying the critical path.

A demolition contractor discovers underground fuel storage tanks not shown on original blueprints. What is the CORRECT next step?

Answer: Stop work, notify the owner and regulatory agencies, and update the project plan

Undiscovered underground storage tanks require immediate work stoppage, notification of the owner and regulators, and project plan revision.

In demolition project scheduling, 'float' or 'slack' refers to:

Answer: The amount of time a task can be delayed without affecting the project completion date

Float (or slack) is the amount of time a non-critical activity can be delayed without delaying the overall project completion date.

When planning the sequence of demolition for a multi-story building, which general principle should guide the work order?

Answer: Work from the top down to maintain structural stability

Demolition generally proceeds top-down so lower structural members continue to support remaining upper floors until they are removed.

Which document specifies the types and amounts of salvageable materials to be recovered before full demolition begins?

Answer: Selective demolition or deconstruction plan

A selective demolition or deconstruction plan identifies salvageable materials, their locations, and the sequence for careful removal prior to full demolition.

A CDS supervisor is developing a waste management plan. Which factor is MOST critical when planning debris hauling schedules?

Answer: Volume of material generated per day matched to truck capacity and disposal site hours

Matching daily debris volume to truck capacity and disposal site operating hours prevents bottlenecks and ensures continuous, compliant waste removal.
