Make a Construction Timeline

A construction timeline lays out a building project from the first drawings to the day the keys change hands: design and permits, site work, the foundation, framing, the trades, inspections and the finishes. It gives the owner, the contractor and the subcontractors the same picture of what happens when. Because each phase waits on the one before it, it also shows how far an early delay pushes everything after it.

The usual phases

Every project is different, but most building and renovation jobs move through the same broad stages:

• Pre-construction: design, engineering, the budget and the contract, then permit applications and approvals.
• Site work: clearing and grading the site, utilities and excavation.
• Foundation and structure: footings, the foundation or slab, then framing and the roof.
• Rough-ins: plumbing, electrical and HVAC run through the open walls, followed by their inspections.
• Close-in and finishes: insulation, drywall, flooring, cabinets, fixtures and paint.
• Closeout: the final inspection, a punch list of small fixes and the handover to the owner.

Keep each phase to its main steps. A timeline that lists every delivery and every crew day stops being readable at a glance, and that level of detail belongs in a schedule. Timeline vs Schedule explains the difference.

Building one in Preceden

Create a timeline and pick the Gantt Chart layout under Choose an initial layout. It lists each step's name down the left, which suits a plan with many short phases. Creating Gantt Charts with Preceden has more on that layout.

Rename the starting layers by clicking their names in the list below the timeline, then use the Add Layer button above the timeline to add more. Give each phase or trade its own layer, such as "Permits", "Site Work", "Structure" and "Finishes". Grouping the work this way turns the timeline into a swimlane timeline, so each part of the job can be followed on its own.

Add each step as an event and choose its phase from the Layer menu. Crews rarely work weekends, so a duration in weekdays often fits better than a calendar end date: type 15 weekdays as the end date and Preceden skips Saturdays and Sundays when it works out where the step ends. Supported Date Formats lists everything Preceden reads.

Link the steps that wait on each other

Most construction steps cannot start until another one is done: framing waits on the foundation, and drywall waits on the rough-in inspections. Open the later step, check Dependent, and choose the step it starts after from the menu. Its start date then follows that step's end date, so if the foundation runs a week late, the framing moves with it, and so does every dependent step after it that has a duration rather than a fixed end date. Dependent Events explains how it works.

After a rain delay or a late permit, the timeline then shows the new finish date on its own.

Mark the dates that matter

Under More Options in the event dialog, check Make this event a milestone on the dates the whole job turns on, such as the permit approval, each inspection and the handover. A milestone has a start date only, and Preceden draws it as a full-height vertical line, so every phase can be read against it. Keep them to a few. Make a Milestone Timeline has more on choosing them.

Track progress as the job runs

As work gets done, pick a Percent Complete value (also under More Options) on each step to shade how much of it is finished. To see the plan against today, click the Appearance button above the timeline, open the Axis section and check Display a line on today's date. Preceden draws a red vertical line at today's date, so anything still unfinished to the left of it is behind. Appearance Settings - Axis covers the other axis options.

Sharing it with the owner and the crew

Our Pro plan lets you invite collaborators, such as a project manager or a site lead, who can update steps alongside you. To keep the owner or a subcontractor informed without letting them edit, share a link or save it as a PDF to attach to an update or a bid.

If you build similar projects, duplicate the timeline when a job is done and reuse it as the starting point for the next one. Preceden doesn't shift every date at once, so change the first step's start date yourself and the dependent steps after it will follow.

The free plan allows up to 10 events on each timeline, which is enough for a phase-level overview. A plan broken down by trade usually needs more, and our paid plans lift the event limit.
