Effort-Driven Activity

b) A task whose duration is calculated based on available resources and their work time.

b) They allow for more accurate estimation of activity durations.

d) The need for fixed-duration activities.

c) Drilling a well to a specific depth.

c) They provide a more accurate and flexible approach to scheduling based on resource constraints.

**Effort-Driven Activities:**

• Site preparation: This task is effort-driven as its duration depends on the size of the site, the type of demolition required, and the availability of construction equipment and labor.
  • Resources: Excavators, bulldozers, demolition crews, skilled laborers.
  • Impact on duration: Larger site = longer duration. More complex demolition = longer duration. Insufficient equipment or labor = longer duration.
• Foundation construction: This task is effort-driven as the duration is determined by the size and complexity of the foundation, the availability of concrete pouring equipment, and skilled laborers.
  • Resources: Concrete mixers, pumps, formwork crews, skilled concrete laborers.
  • Impact on duration: Larger foundation = longer duration. More complex foundation design = longer duration. Limited concrete equipment or labor = longer duration.
• Structural steel erection: This task is effort-driven as its duration depends on the size and complexity of the steel structure, the availability of cranes, and specialized steel erection crews.
  • Resources: Cranes, rigging crews, experienced steel erectors.
  • Impact on duration: Larger structure = longer duration. Complex steel connections = longer duration. Limited crane availability or specialized crews = longer duration.
• Piping and welding: This task is effort-driven as its duration depends on the length and complexity of the piping network, the availability of welding equipment and skilled welders.
  • Resources: Piping, welding machines, qualified welders.
  • Impact on duration: Extensive piping network = longer duration. Complex welding joints = longer duration. Shortage of welding equipment or skilled welders = longer duration.
• Electrical and instrumentation: This task is effort-driven as its duration depends on the complexity of the electrical wiring and instrumentation network, the availability of skilled electricians and instrumentation technicians.
  • Resources: Electrical wiring, control panels, instrumentation equipment, skilled electricians, instrumentation technicians.
  • Impact on duration: Complex electrical wiring = longer duration. Extensive instrumentation network = longer duration. Insufficient skilled electricians or technicians = longer duration.
• Testing and commissioning: This task is effort-driven as its duration depends on the scope and complexity of the testing and commissioning procedures, and the availability of skilled engineers and technicians.
  • Resources: Test equipment, skilled engineers, technicians.
  • Impact on duration: Comprehensive testing requirements = longer duration. Complex commissioning procedures = longer duration. Limited skilled personnel = longer duration.
