Manual schedule and quantity extraction
Engineers still translate plan labels, DGN references, profiles, and sheets into contractor-facing tables by hand.
Engineer-reviewable decision support
Flowline
AI workflow layer for transportation engineering design.
Turn Bentley/MicroStation project data, GIS layers, plan PDFs, and agency standards into schedules, quantities, stormwater impact summaries, and review-ready engineering decisions.
Built around DGN, GIS, plan PDFs, and specifications
Draft outputs with sources, confidence, and review flags
Focused first on drainage, schedules, and stormwater workflows
Problem
The data is there. The engineering output is still manual.
Transportation engineers spend hundreds of hours translating scattered CAD, GIS, plan, specification, and stormwater data into contractor-facing schedules, quantity tables, cost estimates, impact summaries, and design-stage decisions.
Standards and specification overload
DOT work depends on pay items, measurement rules, CAD standards, and agency criteria that are hard to keep aligned.
Design-stage tradeoff decisions
Between 30% and 90% design, teams compare drainage, utility, ROW, grading, cost, and constructability impacts.
Workflow
Project package to engineer-reviewable outputs
Flowline is built as a workflow layer above transportation design artifacts, not a replacement for CAD tools or engineering judgment.

MVP Demo
Operate the Flowline Project Room
The passcode demo lets reviewers scan a representative package, extract a drainage schedule, run an engineer QA pass, and compare stormwater options.

Next: stormwater impact review from full project packages.
The larger vision expands from schedule extraction into full SWM impact review: reports, contours, existing/proposed drainage areas, utilities, grading, POIs, and Tc paths.

Why Flowline
Specific enough to be useful. Careful enough to be trusted.
Flowline is product-forward, technical, and scoped to the workflows where transportation teams already feel the manual burden.
Built for transportation design workflows
Flowline starts with the deliverables civil teams already produce: schedules, quantities, plan references, and draft memos.
Bentley-centered from the start
The product thesis is grounded in MicroStation, OpenRoads, DGN references, DOT workspaces, and agency plan packages.
Standards/specification-aware
The roadmap connects extracted elements to pay items, measurement rules, and state-agency specifications.
Engineer-reviewable by design
Outputs are draft, sourced, confidence-scored, and flagged for human review before they influence deliverables.
Concrete drainage wedge
The first workflow is focused: drainage schedules and stormwater review support, not generic AI for CAD.
