Prefab project budget template
A prefab budget differs from a site-built one because money moves earlier: deposits, factory slots, transport and crane work. This template follows cash by phase, with your own figures.
A prefab budget should show both how much you will spend and when. Because factory production, shipping and lifting are committed early, the cash profile is front-loaded compared with a conventional build. The template below lists the lines most projects need; it has no preset amounts, so every figure is yours.
What changes in a prefab budget
- Earlier commitment. Design must be fixed before production starts, so design fees and decisions come first.
- Deposits and milestones. Suppliers commonly ask for payments tied to production stages. Record the terms the supplier actually states.
- Logistics become a real line. Packaging, transport, insurance, lifting and site access are separate costs.
- Interfaces matter. Foundations, utilities and finishing are often by others and priced elsewhere.
For terminology, see the prefab terminology guide, and for system differences, panelized vs volumetric modular.
Budget by phase
| Phase | Typical cost lines | Question to ask |
|---|---|---|
| Design | Design, engineering, permits | What does design freeze lock in? |
| Production | Factory price, packaging | What is the payment schedule? |
| Delivery | Transport, insurance, duties | Where does the supplier responsibility end? |
| Installation | Crane, assembly, connections | Who supervises and who is liable? |
| Completion | Utilities, finishing, snagging | Is anything left to the owner? |
Use the budget tool
Fill in each line with a quote or your best estimate and note the source in your own records. Lines you cannot yet price are open items, not zero. Adjust the labels to match your project, for example by splitting the factory line into structure, envelope and fit-out if the supplier does.
Check the scope boundary
Most budget surprises sit at the boundary between the factory scope and the site scope. Use the prefab quote exclusions checklist and the scope matrix to assign every item to someone. Then build the delivered cost of imported items with the landed-cost approach.
Before you commit
Have your contractor or cost consultant review the budget, and confirm structural, foundation and permitting assumptions with the engineer of record and the local authority. Prices, deposits and lead times vary by supplier and project, so use the supplier official quotation, not a template, as the basis for any commitment.
Questions people ask
How is a prefab budget different from a site-built budget?
More cost is committed before site work starts: design freeze, factory deposits, transport and lifting. Plan the cash timing as well as the total.
What do owners forget most often?
Foundations, utility connections, site access for delivery, crane or lifting, and finishing work after modules or panels arrive.
Should I include a contingency?
Yes, as its own line with a stated basis. Changes after design freeze are usually costlier than changes before it.
Does the tool give typical prices?
No. It is a blank structure. Enter quotes from your suppliers.
