# Construction

> Document Processing reads pay applications, lien waivers, subcontracts and submittals and cites every figure, so project accountants check facts instead of hunting for them.

## Pay apps and change orders, read line by line.

Document Processing reads pay applications, lien waivers, subcontracts and submittals and cites every figure, so project accountants check facts instead of hunting for them.

Runs on: Document Processing (reads).

| Value | Result | Source |
| --- | --- | --- |
| 36 | file types, scanned or digital | [Perception evaluation](https://nace.ai/perception) |
| #1 | on grounding in Nace's Perception evaluation | [Perception evaluation](https://nace.ai/perception) |
| <½ | the price of the best tool we tested, at the same accuracy | [Perception evaluation](https://nace.ai/perception) |

## Every month, someone rekeys a stack of G703s.

Pay apps, lien waivers and certificates of insurance arrive from every subcontractor in a different format. Document Processing turns them into structured, cited data your project and accounting systems can use.

## Where Nace fits

Document Processing does the reading. Your team and systems take it from there.

| Workflow | What it does | Model |
| --- | --- | --- |
| Pay application extraction | G702 and G703 line items extracted next to the schedule of values, each one cited. | Document Processing |
| Lien waivers and COIs | Dates, amounts, parties and limits extracted from every waiver and certificate. | Document Processing |
| Subcontracts and change orders | Scope, value, retainage and terms pulled from each agreement and change order. | Document Processing |
| Submittal packages | Product data and spec sheets split out of submittal packages and indexed. | Document Processing |
| Document sorting | Every incoming RFI, submittal and letter labeled by type and trade. | Document Processing |
| Field paperwork | Scanned daily reports and field forms read the same way as digital files. | Document Processing |
