The problem

Generating construction payment applications is a manual, error-prone process. A single rounding error or a missing statutory warning on a lien waiver can lead to rejected invoices, payment delays, or voided legal protections.

What it does

• Generates G702 and G703-style progress billing structures with automated retainage and change order math.
• Produces a schedule of values (Continuation Sheet) with column-level reconciliation checks to prevent rounding mismatches.
• Identifies the correct lien waiver type and provides mandatory statutory language for regulated states like CA, TX, and FL.
• Drafts WH-347 certified payroll structures for Davis-Bacon compliance on federal projects, including Statement of Compliance requirements.
• Calculates retainage for completed work versus stored materials based on project-specific rates.

Frameworks & tools

Compliant with US construction standards including AIA-style field structures, Davis-Bacon Act regulations (29 CFR 5.5), and state-specific Property and Civil Codes for lien waivers.

Why this beats prompting it yourself

General LLMs often struggle with the specific "sum of lines" logic required to pass architect review and frequently miss state-mandated legal headers for lien waivers. This skill enforces a 9-line summary reconciliation against the continuation sheet, ensuring the total earned less retainage matches the current payment due to the cent.

Use cases

• Drafting monthly progress billings for general contractors and subcontractors.
• Determining the correct conditional or unconditional lien waiver for a specific state.
• Setting up a Davis-Bacon compliant certified payroll sequence for a new federal job.
• Reconciling stored materials and retainage releases at substantial completion.
