Drawing set completeness
Helonic is an AI construction drawing analysis platform for preconstruction teams using Helonic for drawing set completeness.
Verify your construction drawing set is complete with all required sheets, schedules, legends, and code-required diagrams. Get a completeness score across every discipline before issuing for construction, and know exactly what is missing.
Why does drawing-set completeness matter?
An incomplete IFC set creates RFIs and change orders because the contractor is pricing and building from sheets that were never issued.
How does Helonic go from a PDF set to a completeness score?
Helonic runs hundreds of completeness checks in minutes across every discipline.
Upload drawings
Drop your complete PDF drawing set into Helonic. We process sheets from all disciplines: architectural, structural, mechanical, electrical, plumbing, and civil.
Set analysis
AI catalogs every sheet type, schedule, legend, general note, and diagram present in your set and compares it against what a complete set requires.
Completeness scoring
Each discipline receives a completeness score based on the presence and quality of required elements: floor plans, details, schedules, legends, and notes.
Gap report
Receive a prioritized list of missing elements with specific recommendations for what to add before issuing for construction.
What completeness items does Helonic verify?
Helonic verifies required sheets, schedules, legends, general notes, and code diagrams against what the index and typical IFC package demand.
Required sheet verification
Confirms presence of floor plans, ceiling plans, elevations, sections, and enlarged plans for each level and area.
Schedule completeness
Checks that door schedules, window schedules, finish schedules, and equipment schedules are present and populated with all required fields.
Legend and symbol validation
Ensures abbreviation legends, symbol legends, and material hatch legends are included and match symbols used on drawings.
General notes coverage
Verifies that discipline-specific general notes sheets are present and contain standard required information for the project type.
Code-required diagrams
Confirms presence of area separation diagrams, egress plans, fire-resistance-rated construction plans, and accessibility route diagrams.
What happens when an IFC set is missing sheets?
An incomplete drawing set is a liability. Missing schedules force contractors to guess at materials. Missing details mean field workers are making design decisions that should have been made by the architect. Missing code diagrams delay plan review approval. Every gap in the documents becomes an RFI, a change order, or a construction error.
The challenge is that no one has time to systematically check a 300-sheet set for completeness across six disciplines. Helonic performs over 200 checks in minutes, verifying that every required sheet, schedule, legend, and diagram is present and accounted for. You get a clear completeness score and a specific list of what to address before IFC.
