Evidence before certainty
Sources, calculations, experience, and forecasts remain distinguishable.
Built by Sustainable Gaps
Turn a field pattern into a project decision.
Transformational Approach combines firsthand experience, current market evidence, visible assumptions, and an interactive model to examine how long-lead equipment could affect a live pursuit.
Published evidenceAssumptions remain visibleHuman review before action
The model is a planning forecast. It is not a supplier quote, guaranteed outcome, or substitute for project-specific engineering, commercial, and legal review.
Why it matters
The value is not the forecast alone. It is the path from question to decision.
This work did not begin as a product pitch. It began as a short validation of a plausible field observation. The evidence strengthened parts of the idea, corrected others, and revealed a useful planning application.
- 01
Observe the pattern
The work began with a supply-chain pattern Erik Herring experienced firsthand during the 2021 disruption.
- 02
Test it against current evidence
A five-question review expanded into a dated comparison of procurement activity, market reports, cost indexes, and equipment lead-time records.
- 03
Correct the assumptions
Two claims were narrowed after separate evidence reviews. The corrections remain visible instead of being edited out of the record.
- 04
Build a decision tool
The evidence and assumptions became an interactive model that lets a project team examine how timing could change cost and schedule exposure.
- Evidence reviewed
- 24 source sets
- Corrections retained
- 2 claims narrowed
- Review cadence
- Quarterly
The working model
Change the assumptions. See the exposure move.
The dashboard lets a project team adjust contract value, equipment share, class mix, construction start, order timing, energization risk, and bridge duration. Every result remains a range with its basis available for review.
Interactive project modelAdjust the inputs and review the basis
The model remains a planning forecast. Open the interactive workspace to change assumptions and review the schedule and source notes.
What this demonstrates
Sustainable Gaps can turn an operating question into a governed working tool.
The deliverable is more than a report. SG follows the question through evidence, correction, calculation, interface design, decision ownership, and a practical path for implementation.

A tool built around the decision
The interface exposes the inputs that matter instead of hiding them inside a fixed answer.
Long-Lead Equipment Exposure Assessment
One live pursuit. Defined decision record.
The assessment replaces the reference model's assumptions with the client's equipment list, schedule, available supplier quotes, and current pursuit records.
Scope confirmed before work begins
The fee, timing, and acceptance criteria are quoted after the pursuit's equipment classes, schedule horizon, available records, and required decision outputs are reviewed. No retainer or follow-on obligation is required.
Planned delivery is within 10 business days after complete inputs are received. Timing and scope are confirmed in writing before the assessment begins.
What the team receives
- A long-lead equipment exposure register based on the reviewed pursuit
- Schedule and cost scenarios by equipment class and planned start year
- Commercial risk considerations for the estimator, client, and legal counsel
- A bridge-power scenario with decision dates, permitting considerations, and exit criteria
- A client-facing summary of the evidence, assumptions, options, and decision points
- A 60-minute readout with the estimating team
Start with the decision
Bring the pursuit, its current stage, and the question your team needs answered.
Sustainable Gaps will determine whether this assessment fits the situation before a scope is proposed.
