Put your own numbers in. Read what they imply.
No account, no card. Every calculator shows its result on the page. The email is asked for only when you want the PDF. Under twelve inputs each. Every result has a permalink you can send to a colleague.
Pre-GMP Readiness Score
A score out of 100 with a band, from six weighted sub scores: design completeness, contingency adequacy, allowance basis, schedule realism, buyout coverage and scope definition. The weakest line is named first, in plain words.
Contingency Runway
The month the contractor's contingency runs out at the current burn rate, how many months of construction follow it, and the burn ratio: points of contingency drawn per point of work built. Same projection function as the product.
Six more, each with one job.
Supporting calculators. Each takes your figures and shows what they imply. None of them supplies an assumption of ours. Escalation rates, split percentages and float are what you type.
GMP, buyout savings to date, packages awarded and remaining, allowance overruns, projected unused contingency, split percentages, any cap. Output: the pool, your share, the contractor's share, and a sensitivity table for open change orders.
See the module it mirrors By causeChange Order ExposureOpen items by cause classification. Output: owner cost and contractor cost, split, with the unclassified value shown in the flag color.
Read how the split works Your rates, not oursEscalation and Market RiskUnbought packages by US region with the escalation rate you enter. Output: exposure on the unbought scope against the escalation allowance carried.
Read about contingency by stage Critical pathSchedule Risk versus FloatCritical path activities, float in days, monthly general conditions. Output: how many activities carry zero float and what a month of delay costs under the contract.
Read the schedule of values guide Per allowanceAllowance Confidence BandCarried value and design completeness when each allowance was set. Output: a band around each carried value, by a stated rule, and the aggregate exposure at the bottom.
Read why the band widensCost Influence Curve
The pattern behind every tool: the ability to influence cost falls as the project advances while the cost of a change rises. A recognized industry pattern, not a measurement of ours. Every calculator result links back to it.
The library calculators open in the product's calculator view during the demo. On this page they are described, with the article that explains each one. Every result page in the product ends with the same three items: the relevant scenario, the relevant review, and the PDF.
Questions owners ask
Do I have to enter an email to see the result?
No. Every calculator shows its result on the page. The email is asked for only if you want the three page PDF.
Where do the benchmarks come from?
There are none presented as ours. Where an industry pattern is referenced it is labeled as a recognized industry pattern. Every figure on the result is computed from the inputs you typed.
Is the result stored?
The inputs and the result are stored anonymously so the calculators can be improved. No personal data is kept unless you ask for the PDF.
Run it on the real ledger.
The calculators take typed inputs. The product takes the registers. Thirty minutes on a call shows the difference.
