PSP Exam Dumps - Planning & Scheduling Professional (PSP) Exam

Total float is influenced by factors like multiple calendars, start/finish constraints, and preferential logic because these directly affect the calculation of early and late dates.

Option D (front end loading), which involves distributing work to earlier project phases, does not inherently affect float calculations as it primarily pertains to resource or phase management strategies​​.

ï‚· Definitions of Delays

Excusable Delay: These are delays not caused by the contractor and may be beyond their control. They can be compensable (entitling the contractor to both time and monetary compensation) or non-compensable (entitling only time extension). Examples include acts of God or owner-caused delays.

Non-Excusable Delay: These delays are caused by the contractor, such as poor planning or lack of resources. Non-excusable delays do not qualify for any compensation or time extensions.

Compensable Delay: A type of excusable delay caused by the owner or their representatives that entitles the contractor to both time extension and additional compensation.

Non-Compensable Delay: An excusable delay that entitles only time extension but no monetary compensation (e.g., natural disasters).

 PSP Study Guide Reference: The PSP Study Guide emphasizes understanding the types of delays to analyze their impacts on schedules and costs. Non-excusable delays, which result from the contractor's actions, are clearly categorized as not providing grounds for time extensions or additional payments​.

ï‚· Analysis for Selection:

Option A: Non-excusable delays do not provide contractors with any extensions or compensation as they result from the contractor’s responsibility.

Option B: Compensable delays provide both time and compensation and do not match the question's condition.

Option C: Non-compensable delays, though they provide no monetary compensation, can allow time extensions under certain circumstances.

Option D: Excusable delays generally entitle contractors to time extensions, with or without compensation depending on the type.

ï‚· Conclusion: The correct answer is A. Non-excusable delay, as these delays provide neither time extensions nor compensation to the contractor.

ï‚· Interpret the Narrow Band at "Y":

The narrow band at "Y" is located on a part of the schedule where activities have been delayed or slowed down.

Such delays typically indicate resource limitations (e.g., insufficient manpower or equipment).

ï‚· Reasoning:

No evidence of rework or activity inactivity is explicitly shown in the diagram.

Resource limitations are common in network diagrams to explain such periods.

ï‚· Cross-Verification:

Option B: Incorrect. No evidence of rework exists.

Option C: Incorrect. Activity inactivity does not fit the context.

Option D: Incorrect. Sufficient information is provided.

Option A: Correct. Resource limitation fits the observed diagram behavior.

ï‚· Proceeding without completing environmental studies introduces compliance risks, such as legal challenges or project shutdowns. This is not a feasible method for reducing the overall completion time as it contradicts environmental regulations and ethical standards.

ï‚· Methods like subcontracting (A) or reallocating resources (B) are feasible, as they leverage resource management.

 References: PSP Study Guide, Section 1.2.3 – Stakeholder Considerations, and Section 1.3.13 – Risk and Recovery Planning, which emphasize compliance with regulations and avoiding unmanageable risks.

ï‚· Workweek Period Analysis:

Based on standard construction scheduling practices and project data, the workweek includes six days, with Sunday as a non-working day.

ï‚· Verification in Project Details:

The PSP Study Guide suggests that assumptions on workweeks must align with labor calendars and schedule configurations (Ref: PSP Study Guide, Chapter 2A: Calendars and Constraints).

ï‚· Granting Time Extensions:

Differing site conditions are excusable delays under standard contract terms, requiring time extensions.

Centrifuge delays and shop drawings typically fall under the contractor's responsibility and are not excusable.

ï‚· Excluded Options:

A & B: Shop drawing-related delays are the contractor's risk unless explicitly agreed otherwise.

D: Combining excusable and non-excusable delays does not entitle an extension.

ï‚· Verification with PSP Guidelines:

Granting time extensions aligns with contractual principles outlined in PSP-related contracts (Ref: PSP Study Guide, Chapter 1C: Delay Analysis and Claims).
