Extract project data, amounts, dates, and compliance details from lien waivers, change orders, AIA G702/G703, and construction submittals—without manual entry.
Upload any document — PDF, scan, or photo — and get structured data back immediately. No setup, no templates, no waiting.
Drag and drop files, connect a cloud drive, or set up email auto-forwarding. Any file format works—PDF, JPEG, PNG, TIFF, or digital documents.
The AI identifies fields by context and meaning, not fixed coordinates. Names, dates, amounts, and custom fields are extracted automatically.

Construction projects generate a continuous stream of documents that track financial commitments, compliance requirements, and project progress. Lien waivers confirm that subcontractors and suppliers have been paid. Change orders modify the original contract scope and price. AIA pay applications (G702/G703) track progress billing across every line item of a project. Submittals document material approvals. Each of these document types contains critical data that project managers, owners, and lenders need to track accurately.
Construction document OCR is distinct from general-purpose document processing because of the industry-specific formats and the interconnected nature of the data. A lien waiver references a specific pay period, project, and subcontractor. A change order modifies specific contract line items and affects the overall contract value. An AIA G703 continuation sheet contains dozens of line items with original values, previous applications, current work, stored materials, and retainage—all of which must be extracted accurately to maintain project financial controls.
The compliance dimension of construction documents adds urgency to automation. General contractors and owners must collect lien waivers from every subcontractor and material supplier before releasing payment, and failure to do so creates lien risk. Tracking this across a project with 50 subcontractors and monthly pay periods means managing hundreds of lien waivers manually. Lido extracts waiver type, subcontractor name, project reference, through date, and conditional/unconditional status automatically, enabling compliance teams to verify completeness without reading every document.
Construction firms evaluating document OCR should prioritize accuracy on AIA forms and lien waivers, support for state-specific lien waiver formats, integration with project management and accounting systems, and batch processing capability for monthly pay application cycles. Lido handles all standard construction document types without templates and provides SOC 2 Type 2 compliance for sensitive project financial data.
“We track lien waivers from 60 subcontractors across 8 active projects. Automated extraction replaced a full-time administrative role and reduced our lien risk exposure by ensuring no payments go out without verified waivers.”
“AIA G703 data entry was our most error-prone process. Miskeyed line item amounts on continuation sheets created payment discrepancies that took days to reconcile. Automated OCR eliminated those errors.”
“Change order tracking across a $200M project was drowning our team in paperwork. Now every change order is automatically parsed with scope, amount, and approval status extracted for our project controls dashboard.”
Audited controls over a sustained period, not a point-in-time check.
Bank-grade encryption at rest and TLS 1.2+ in transit.

Construction OCR handles lien waivers (conditional and unconditional), change orders, AIA G702 Application for Payment, AIA G703 Continuation Sheets, submittals, RFIs, daily reports, and certificates of insurance. The AI identifies the document type and extracts the relevant fields automatically.
The AI extracts all fields from AIA pay applications including contractor information, project details, original contract sum, change orders to date, current payment due, and retainage. G703 continuation sheets are processed line by line, extracting item numbers, descriptions, scheduled values, previous applications, current work, stored materials, and balance to finish.
Yes. Lien waiver requirements vary by state, with some states mandating specific statutory forms. The AI handles all common lien waiver formats including California, Texas, Florida, New York, and other state-specific variations, extracting waiver type, amounts, dates, and project references.
Individual documents process in under five seconds. During monthly pay application cycles when dozens of subcontractors submit packages simultaneously, batch processing handles the entire volume in minutes rather than the hours required for manual data entry.
Extracted data can be exported to Excel, Google Sheets, CSV, or JSON. The REST API enables integration with construction project management systems like Procore, Sage 300, and Viewpoint, as well as construction accounting platforms.
