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.

Preventing Structural Steel Delays:
* Incorporating realistic timeframes for shop drawing review and resubmittals in the baseline schedule prevents design-related delays.
Evaluation of Other Options:
* A: Adding time buffers does not address the root cause.
* C: Concurrent review may create confusion and errors.
* D: Switching to post-tensioned concrete is a significant design change, not a practical solution for a scheduling issue.
Verification with PSP Guidelines:
Adequate review time aligns with PSP scheduling best practices (Ref: PSP Study Guide, Chapter 2B:
Schedule Development and Baseline Creation).
