Construction Scheduling
The sequence of activities that determines the overall duration of the project.
What is the critical path?
PPE required when working at heights to prevent falls.
What is a harness (fall protection)?
A contractor request used to clarify unclear drawings or specs.
What is an RFI?
A formal change to cost, schedule, or scope in a contract.
What is a change order?
This type of soil has high cohesion and retains water, making it difficult to compact when wet.
What is clay?
The amount of time an activity can be delayed without affecting successor activities.
What is free float?
The OSHA standard that requires protective systems for trenches 5 feet or deeper.
What is excavation/trenching protection requirement?
Documents issued by suppliers for review before fabrication or installation.
What are submittals?
The process of selecting and awarding subcontracts.
What is procurement (or buyout)?
The process of ensuring circuits are de-energized and cannot be re-energized during work.
What is lockout/tagout (LOTO)?
A relationship where a successor cannot start until a predecessor finishes.
What is Finish-to-Start (FS)?
The competent person is responsible for identifying and correcting these on site.
What are hazards?
The official log that tracks all submitted, reviewed, and approved documents.
What is a submittal log?
The difference between Earned Value and Planned Value.
What is schedule variance (SV)?
The phenomena where vapor bubbles form and collapse in a pump, potentially causing damage.
What is cavitation?
A delay added between activities to reflect real-world constraints.
A delay added between activities to reflect real-world constraints.
A written permit required before performing high-risk tasks like confined space entry.
What is a permit-to-work?
This ensures crews are building from the latest drawing version.
What is version control (or revision control)?
A structured process for identifying, analyzing, and mitigating uncertainties.
What is risk management?
This project delivery method involves a single contract where the contractor is responsible for both design and construction.
What is Design-Build?
This analysis compares planned progress to actual progress to identify schedule variance.
What is schedule performance analysis (or Earned Value schedule analysis / SPI)?
This analysis determines potential incident severity and likelihood before work begins.
What is risk assessment (or hazard analysis matrix)?
A formal system that tracks document lifecycle, approvals, and access.
What is a Document Management System (DMS)?
The forecasted total cost of a project based on current performance.
What is Estimate at Completion (EAC)?
Reinforced concrete includes this material to improve tensile strength.
What is rebar (reinforcing steel)?
