Free Gantt chart template for architecture projects. Plan building design phases, permit timelines, construction hand-offs, and client review cycles.
Architecture projects are long, multi-phase, and dependent on external approvals that move at their own pace. A residential addition might take 14 months from initial client meeting to certificate of occupancy — and the project cannot move from schematic design to design development until the client signs off. It cannot move from design development to permitting until the drawings are stamped. Permits cannot be pulled until the authority having jurisdiction (AHJ) processes the application, which could take 4 weeks or 4 months depending on the municipality.
A Gantt chart makes all of these dependencies visible in one view. Clients see the overall timeline without drowning in technical detail. Contractors see when they come into the project. The architecture team sees where reviews and approval gates fall, so they can plan work around the waiting periods.
This template covers residential and commercial architecture projects. It is free to use in gantt-chart.io with no account needed.
Architecture projects typically follow the phases defined by the American Institute of Architects (AIA):
| Phase | Key Deliverables | Who Approves |
|---|---|---|
| Pre-Design / Programming | Site analysis, program requirements, project budget | Client |
| Schematic Design (SD) | Concept drawings, floor plan options, site plan | Client |
| Design Development (DD) | Developed drawings, material selections, preliminary specs | Client |
| Construction Documents (CD) | Permit-ready drawings, full specification package | AHJ / Building Department |
| Bidding / Procurement | Contractor selection, bid analysis, contract award | Client + legal |
| Construction Administration (CA) | Site visits, RFI responses, submittal review, punch list | Contractor |
| Project Closeout | Certificate of occupancy, as-built drawings, warranty docs | AHJ + Client |
| Phase | Tasks | Typical Duration |
|---|---|---|
| Pre-Design | Site visit, as-built survey, zoning research | 1–2 weeks |
| Schematic Design | Concept sketches, client presentation, revision round | 3–5 weeks |
| Design Development | Developed plans, material schedule, structural coordination | 4–6 weeks |
| Construction Documents | Full drawing set, energy compliance, structural drawings | 6–10 weeks |
| Permit Submission | Submit application, respond to plan check comments | 4–16 weeks (AHJ dependent) |
| Bidding | Distribute documents, receive bids, level proposals | 3–4 weeks |
| Construction | Foundation through finish | 4–12 months |
| Closeout | Punch list, final inspections, CO | 2–4 weeks |
| Phase | Tasks |
|---|---|
| Programming | Space needs analysis, lease review, code research |
| Schematic Design | Test fits, concept layouts, landlord coordination |
| Design Development | Final floor plan, reflected ceiling plan, finish schedule |
| Construction Documents | Permit set, MEP coordination, accessibility compliance |
| Permit | Building department review, fire marshal, health department if applicable |
| Bidding | General contractor RFP, leveling, contract negotiation |
| Construction | Demo, rough-in, framing, finishes, FF&E install |
| Closeout | Punch list, inspections, certificate of occupancy |
Step 1: Open gantt-chart.io. No sign-up required.
Step 2: Create a project and add each AIA phase as a group. Add individual tasks within each phase. For small residential projects, groups are the phases; for large commercial projects, each phase might be broken into 5–15 tasks.
Step 3: Mark permit submission as a milestone with a fixed expected date and add a permitting buffer of 4–12 weeks depending on the jurisdiction. This is the biggest source of schedule uncertainty on most projects — building it in from the start manages client expectations.
Step 4: Set client review and approval gates as milestones. The transition from SD to DD cannot start until the client approves SD. Make that dependency explicit in the chart so clients understand that delays in their review push the entire schedule.
Step 5: Share the chart with the client, contractor, and consultants. Copy the link and include it in every project update email. Clients who can see the timeline are less likely to ask "when will we be done?" and more likely to prioritize their own review deadlines.
1. Treat permit review as a variable, not a fixed date. Small municipalities and overloaded building departments regularly take 2–4 times longer than their published review timelines. Always show permit review as a range on the chart and communicate to clients that this phase is outside the team's control.
2. Build in three days of buffer for each consultant coordination cycle. Structural, mechanical, electrical, and plumbing engineers all need turnaround time. Do not schedule CD delivery the same day the structural engineer returns redlines — assume 3–5 days of integration work after each coordination round.
3. Show contractor mobilization as a task. The gap between permit issuance and contractor start is often underestimated. Contractors need to schedule subcontractors, order long-lead materials, and process their own permits before ground breaks. This can take 2–6 weeks and should appear in the chart.
4. Flag long-lead items as early tasks. Steel, custom windows, elevators, and specialty finishes often have 8–20 week lead times. If these are ordered during construction documents rather than during bidding, the schedule slips. Add a "long-lead procurement" task that starts as soon as selections are made.
5. Schedule client reviews at fixed intervals. Clients who do not have a deadline for their review tend to take longer. Put "Client review and approval — SD" as a task with a 5-business-day window. If the client misses the window, the chart shows the downstream impact.
Q: How do I show permit uncertainty in the Gantt chart?
Add a "Permit review" task with a minimum duration (the jurisdiction's stated timeline) and a note in the task description listing the actual range. Some teams add two rows: "Permit best case" and "Permit expected" to show the optimistic and realistic scenarios side by side.
Q: Should I share the construction schedule with the architecture team's Gantt chart?
Keep them separate. The architecture team's chart covers design and administration. The contractor's schedule covers construction in detail. Link them at the handoff milestone: when the contractor's schedule is approved, add a link to it in the CA phase.
Q: How do I handle a project that stalls during permitting?
Do not leave the chart frozen. Update the permit task's end date to the current expected approval date. Push all downstream tasks. Share the updated chart with the client immediately. Waiting to update the schedule until permits clear is a common mistake that produces a surprise at the end.
Q: What software do contractors use for construction scheduling?
Contractors typically use Primavera P6 for large commercial projects, Procore Schedule for mid-size projects, or Microsoft Project. For the architecture team's project management purposes, gantt-chart.io handles the design and administration phases without requiring any software installation.
Q: How detailed should the construction administration phase be in the Gantt chart?
CA is often shown as a single bar spanning the construction period. Add milestones at key inspection points (framing inspection, rough-in inspection, final inspection) so the team knows when site visits are needed.
