Why Your Construction Schedule Isn’t Working: 10 Common Scheduling Mistakes That Lead to Delays, Claims, and Project Risk

A construction schedule should do more than satisfy contract requirements — it should provide a reliable roadmap for project execution and clear insight into project performance. Yet many schedules contain hidden issues that make it difficult to identify risk, evaluate delays, or make informed decisions.
 
In this webinar, ACE Consulting’s scheduling experts discuss the 10 most common scheduling mistakes found on construction projects and explain how these issues can lead to delays, claims, and increased project risk. From broken logic and excessive constraints to unrealistic critical paths and poor update practices, this session provides practical guidance to help project teams improve schedule quality and reliability.

What You Will Learn


Identify Missing or Broken Logic

Learn why activity relationships are essential to a reliable schedule and how missing or incorrect logic can distort the project timeline and hide potential delays.

Understand the Impact of Excessive Constraints

Discover how overusing constraints can artificially manipulate project dates, create unrealistic schedules, and prevent teams from accurately assessing project performance.

Evaluate Critical Paths and Float

Explore how critical paths can become misleading, what negative float may indicate, and how float analysis can help identify schedule risk before it affects the project.

Recognize Out-of-Sequence Progress

Understand how out-of-sequence work impacts schedule calculations, reporting, and forecasting, and learn best practices for managing progress updates.

Improve Activity Durations and Sequencing

See how unrealistic durations, poor sequencing, and incomplete planning can create inaccurate schedules that fail to reflect actual project conditions.

Strengthen Schedule Updates and Documentation

Learn common schedule update mistakes, the importance of documenting assumptions and changes, and how proper reporting practices improve communication and reduce risk.

Perform Simple Schedule Quality Checks

Discover practical quality checks that project teams can use to identify scheduling deficiencies and improve overall schedule reliability.
