Bell-curve planning view
P50 is the most likely cost zone, while P70 and P90 give progressively safer planning positions.
Methodology
VisionBuild Cost Prediction
VisionBuild Cost Prediction helps owners understand what a project may cost, how much uncertainty sits inside that number, and where the biggest cost drivers should be managed before construction begins.
Overview
Built for owners who need clarity and control.
Traditional estimates usually hand over one price with contingency buried inside it. VisionBuild Cost Prediction opens that up. It shows the base estimate, the likely cost range, the bell-curve-style spread of outcomes, and the main cost drivers so owners can make decisions with more confidence. That methodology is strengthened by a background that combines finance and investment training, carpentry and renovation knowledge, renewable-energy education, formal construction-management certification, and PMI-CP project credentials.
Step-by-step process
The methodology reviews the project, breaks the work into cost packages, builds a base estimate, compares it to similar jobs, identifies key risks, assigns realistic ranges, runs the cost model, and then explains the results in plain language so the owner can understand what is driving the budget.
Bell-curve cost view
Instead of pretending there is one perfect number, VisionBuild Cost Prediction shows a range of possible outcomes. The middle of the bell curve shows the most likely result, while higher-confidence points such as P70 and P90 show what a safer planning number may look like when renovation or coordination risk is higher.
Sensitivity analysis
Sensitivity analysis highlights which few items can move the total budget the most. In simple terms, it shows where management attention matters most so the team can focus effort on the biggest budget drivers instead of treating every line item the same.
Shared-savings integration
When target-cost logic is paired with an open-book delivery model like VBCD, the owner can see both the target basis and the actual cost basis. That makes shared savings easier to explain and easier for a client to trust, because the logic is visible instead of hidden inside a lump-sum number.
How VisionBuild applies it
At concept stage the team builds an early range and risk map. Through design development and pre-tender, the estimate is refined with market pricing and clearer cost distributions. During delivery, actual cost can be tracked against the target so the owner can see whether the job is holding, improving, or moving off course.
Visual guide
How owners read the cost picture
The diagrams below turn the methodology into a client-facing view of what the numbers mean. They make it easier to understand the likely cost range, the few inputs that move the budget most, and how upside stays visible when an open-book target-cost structure is used.
Sensitivity priorities
A tornado-style view shows which few issues deserve the most management attention.
How upside stays visible
When actual trade cost comes in below the target basis, the owner can see that change clearly instead of losing it inside a hidden lump-sum structure.
| Target basis | Budget is built from open assumptions and visible cost packages. |
| Actual cost basis | Real trade pricing is compared against the target as the job develops. |
| Owner upside | If the work performs better than expected, the saving can be returned or shared by agreement because the cost path is visible. |
