How to Create a Construction Project Timeline That Actually Works
Why Most Timelines Fail
Over 70% of construction projects run past their deadline. The root cause is almost never a single delay — it is cascading dependencies that were not properly mapped at the start.
Start With the Critical Path
Identify the longest sequence of dependent tasks. This is your critical path — any delay here delays the entire project. Everything else has float.
Buffer Strategically
Add buffers at merge points, not on every task. A 10% buffer at each stage compounds into massive overestimation. Instead, place project buffers at key milestones.
Use Pull Planning
Work backwards from the handover date. Each trade commits to what they need done and by when. This creates ownership and surfaces conflicts early.
Weekly Look-Ahead Schedules
Maintain a rolling 3-week look-ahead that is updated every Monday. This catches drift before it becomes a crisis.
