Groundbreaking is a milestone. So is 50% design, permit approval, and the order date for the chiller. Too often, precon is managed in spreadsheets and emails—deliverables slip, no one owns the delay, and the construction start date slides. The critical path doesn't begin at mobilization. It begins when the project is conceived. Treating precon milestones with the same rigor as construction pays off in predictable start dates and fewer surprises. Simple automation—a shared tracker with due dates, owners, and automated reminders when items are overdue—keeps precon visible without requiring heavy software. The same tools that track construction tasks can track design deliverables and procurement; the shift is behavioral, not technical.
What Precon Milestones Typically Include
Design: 30/60/90/100% deliverables, design team reviews, owner approval gates. Permits: applications submitted, review status, approval date. Procurement: long-lead item list, order dates, delivery dates, sub buyout status. Contracts: GMP or lump sum executed, insurance and bonds in place. Each has an owner, a due date, and dependencies. When one slips, downstream milestones shift. Visibility—a simple dashboard or schedule—makes that visible before it's critical.
Where This Shows Up on a Real Project
You're targeting a June 1 start. The electrical gear has a 16-week lead time. Order date was supposed to be February 1. It's February 15 and the sub hasn't been awarded because the electrical design wasn't finalized until January 20. No one connected the dots. A precon schedule with design → buyout → order → delivery would have shown the link. You'd have compressed design or adjusted the start date months ago.
Start Here This Week
- Build a precon milestone list: design gates, permit milestones, long-lead items, buyout targets, contract execution. Assign an owner to each.
- Put milestones on a timeline—Gantt, simple bar chart, or even a spreadsheet with dates. Show dependencies.
- Review weekly. What's at risk? What slipped? Who's accountable for recovery?
- Tie long-lead procurement to design completion. Don't assume you can order before the design is locked.
- Communicate milestones to the owner and design team. Shared visibility reduces finger-pointing when dates slide.
Risks and Guardrails
- Over-planning: Precon has uncertainty. Don't create a schedule so detailed that it becomes fiction. Focus on the milestones that drive the start date.
- Ownership gaps: "The architect" or "the owner" isn't enough. Name individuals. Ensure they have authority to deliver.
- Change orders: Scope changes during precon reset milestones. Document the impact and revise the schedule when changes occur.
- Automation: Tools can track and remind. They can't negotiate with designers or expedite permits. Use tech to support, not replace, proactive management.
