Evidence first
Every important project fact should retain the plan, schedule, correction, or other evidence that supports it.
How True to Plan works
Keep the plan truth connected all the way to the bid.
True to Plan turns governing project documents into canonical plan intelligence, evidence-linked takeoffs, trade-specific estimating, focused review, and proposal revisions without asking the contractor to rebuild the job at every step.
01
Governing plans
SOURCEPDF, CAD, DWG, schedules, addenda, and referenced documents remain the source record.
02
Plan intelligence
CANONICALCanonical objects and effective facts preserve exact sheet, view, evidence, and revision lineage.
03
Takeoff + object facts
PHYSICALAutomatic physical quantities and construction properties become reusable project inputs.
04
Trade packages + estimate
TRADEEach supported trade applies its own construction and commercial logic to the shared inputs it owns.
05
Review Center + Eddy
REVIEWMaterial exceptions, assumptions, and unresolved decisions are surfaced for contractor judgment.
06
Proposal + revisions
OUTPUTReviewed scope and pricing publish forward without overwriting the plan truth or prior revisions.
Architecture contractors can feel
Automation without losing the reason behind the number.
One effective value
Normal work surfaces show the current defensible value; competing observations stay in provenance and review instead of crowding the drawing.
Shared facts
A wall, opening, room, equipment requirement, or other physical fact can support more than one downstream consumer without being copied into separate truths.
Trade ownership
Shared physical truth does not mean generic estimating. Supported trade compilers own the derivation, labor, waste, procurement, and commercial logic appropriate to that trade.
Contractor judgment
AI and automation can help organize, explain, and surface exceptions. They do not silently invent missing construction truth or commercial decisions.
Shared truth, specialized consumers
Measure the physical project once. Use it correctly downstream.
The same resolved physical fact can be read by multiple authorized consumers while each supported trade keeps ownership of its own estimating transformation. That prevents the project from accumulating different versions of the same wall, opening, dimension, or quantity.
