Facade Cost Budget Workbook
A free, openable XLSX estimating template for facade procurement teams: line-item cost structure, editable 2026 unit rates, system benchmarks and a 50-year lifecycle note — so a first-pass facade budget takes an afternoon, not a week.
What Is Inside the Workbook
Four sheets, zero placeholders. Open it, replace the sample project with yours, and read the budget line.
| Sheet | What it does | Key content |
|---|---|---|
| How to Use | One-page instructions, volume rules and assumptions | Usage steps, caveats, and what the workbook is not |
| Project Setup | Enter the project parameters that drive every downstream number | Facade area, storeys, system type, glazing spec, wind zone, schedule |
| Cost Estimate | Line-item budget with editable unit rates and live formulas | 12 line items from engineering to contingency, subtotal and total |
| Benchmarks & Notes | Reference ranges so the estimate can be sanity-checked | Seven system families in USD/sqm plus lifecycle cost notes |
Compatible: opens in Excel, Google Sheets, LibreOffice and Numbers. Sample project is a 12,000 sqm unitized office tower in East China; every yellow input cell is editable, so the workbook works for any market.
The Line-Item Discipline That Prevents Budget Surprises
Most facade cost overruns are not caused by wrong unit rates. They are caused by missing line items: testing and mock-ups, permanent access, packing and logistics, and the contingency that absorbs design changes. The workbook encodes the same checklist Hanart engineers use when they scope a budget internally, before a formal quotation.
The Cost Estimate sheet carries twelve line items. Engineering and design development covers shop drawings, thermal and structural calculations and BIM coordination. Materials are split into aluminium framing, the glass package, sealants and gaskets, and anchors and embedments — each with its own editable rate, because these prices move independently of each other. Site installation and glazing is a separate line from unit assembly, which matters for high-rise projects where crane and hoist access dominates labour. Performance testing and mock-up is a lump sum, because a full-scale unit mock-up is the single most reliable way to protect waterproofing performance. Site preliminaries and access, project management and documentation, and a 5% contingency close out the scope.
Every computed cell is a live formula, so changing the facade area or any unit rate updates the subtotal and total automatically. A per-square-metre indicator cell makes the result comparable across schemes. The Benchmarks sheet then provides the sanity check: a unitized system should land in the USD 520–640 per square metre planning range for 2026 delivery; a stick-built or aluminium panel scheme should be lower; a double-skin facade significantly higher.
The lifecycle note is deliberately included. A facade commonly costs 1.5–3.0 times its first price over 50 years once cleaning, sealant renewal, hardware and glass replacement are added. That single sentence reframes every low first-cost bid, and it is why the 50-year lifecycle cost math deserves a place in the same folder as this workbook.
From Workbook to Decision-Grade Budget
Step 1 — Download and fill in Project Setup. Change the sample project to your facade area, storeys, location and system type. Keep the unit rates as published for a first pass, or adjust them to your market intelligence.
Step 2 — Read your planning range. The Cost Estimate total shows a rough order of magnitude. Compare it against the Benchmarks sheet to confirm the system family is in the right band. If the number is unexpectedly high or low, the line items show exactly where the assumption sits.
Step 3 — Pressure-test the five lifecycle streams. Add a maintenance and renewal column beside the first cost using the facade cost in 2026 article and the lifecycle cost guide. Owners who compare total cost of ownership rarely pick the cheapest first-cost bid.
Step 4 — Get the project number. A workbook is a checklist, not a quotation. Submit an RFI with the setup sheet attached; Hanart's engineering team returns a scoped line-item budget and reference documentation, usually within 48 hours.
Turn the Workbook Into a Priced Budget
Send the filled setup sheet through the RFI and the team will price the project with drawings, wind zone and access assumptions — no obligation, engineering input included.
Workbook Questions, Answered
Yes. The workbook is free and opens directly as an XLSX file in Excel, Numbers, LibreOffice and Google Sheets. It is released as a planning tool so procurement teams can structure a first-pass facade budget before asking for a formal quotation.
The Cost Estimate sheet uses editable 2026 planning rates in USD per square metre for a unitized curtain wall, benchmarked against Hanart delivered projects and public market data in East Asia and the Middle East. The Benchmarks sheet compares seven system families from stick-built to double-skin.
No. The workbook is a budgeting checklist, not a priced bill of quantities. A project-specific price is issued through the RFI process once drawings, specification, wind zone and access strategy are known.
Submit an RFI with the facade area, system type, storey height and location. Hanart's engineering team returns a scoped budget and a line-item comparison within about 48 hours.
