# AI Preconstruction Software for General Contractors

Piper is the AI operating system for preconstruction. It connects drawings, specifications, addenda, quotes, estimates, and company knowledge so general contractors can generate scopes, level bids, and review risk with every finding linked to its source.

Piper is the AI operating system for preconstruction.

It gives general contractor preconstruction teams one evolving understanding of the project by connecting drawings, specs, bids, company knowledge, and live project context.

It is not a document chatbot that only answers questions about project files.

It is not a collection of disconnected AI point tools for individual preconstruction tasks.

It is for general contractor preconstruction teams, especially estimators and preconstruction managers.

Piper maintains one evolving understanding of the project across preconstruction, with findings grounded in source documents and changes carried through the workflows they affect.

## Too much preconstruction time is spent assembling information, not improving the work

### Days are lost finding, extracting, and reconciling information across drawings, specs, addenda, quotes, schedules, and spreadsheets

### Historical costs, company standards, and lessons learned remain scattered across files and people

### Senior team members cannot personally review every scope, bid, estimate, schedule, and project decision

### Late changes and manual reviews create scope gaps, rework, missed dependencies, and margin risk

Piper turns that fragmented process into a repeatable preconstruction system

## Start with the preconstruction job in front of you

### Scope Generation

Turn drawings, specifications, addenda, and company standards into source-backed trade scopes.

### Bid Leveling

Compare subcontractor bids against the intended scope so the low number does not hide an expensive gap.

### Final Bid Review

Review the estimate against the project behind it and focus senior attention on what still deserves judgment.

### Survey

Turn your company's experience into a repeatable survey that captures what the team learns and improves over time.

## How it works

Turn scattered project information into connected preconstruction work

### 01. Unify the project: Unify the project

Bring drawings, specs, addenda, subcontractor quotes, estimates, and spreadsheets into one connected project context.

### 02. Apply your company knowledge: Apply your company knowledge

Piper combines the live project with your historical data, templates, standards, and expert checks.

### 03. Produce and verify the work: Produce and verify the work

Create and review scopes, bid leveling sheets, estimates, project reviews, and other preconstruction deliverables in your own formats, with every finding linked to its source.

Piper removes busy work from the critical path and turns the package into decision-ready, source-linked clarity

## Protect your margins early

Bring a current or completed project and see how Piper saves review time, surfaces scope gaps, and applies your company's knowledge, with every finding linked to its source. See our [Privacy Policy](https://piper-ai.com/privacy-policy).

## What general contractors ask

### What is AI preconstruction software?

Piper is the AI operating system for preconstruction. It gives general contractor preconstruction teams one evolving understanding of the project by connecting drawings, specs, bids, company knowledge, and live project context.

### Is Piper a takeoff or estimating tool?

No. Piper is the AI operating system for preconstruction. It is not a takeoff or estimating calculator, not a document chatbot that only answers questions about project files, and not a collection of disconnected AI point tools.

### Does Piper replace estimator judgment?

No. Piper does the extraction, reconciliation, and cross-checking so estimators can spend their time deciding which differences matter. Consequential assumptions and the final number remain estimator decisions.
