# Piper vs. Procore, BuildingConnected and PlanHub for bid leveling

1. Bid management platforms and Piper do different jobs, and most GCs will use both
2. Platforms such as Procore, BuildingConnected and PlanHub run solicitation, bid collection and coverage
3. Piper reads each bid against the drawings, specs, addenda and your scope standards, and links every gap to its source
4. Pick by the question you need answered: who bid and at what price, or what each bid really covers

**Procore, BuildingConnected and PlanHub are bid management platforms: they help a general contractor invite subcontractors, collect bids and track coverage. Piper is an AI preconstruction system: it reads each bid against the drawings, specifications and addenda to show what the bid covers and what it leaves out.** They overlap at the leveling sheet, and that overlap is where the choice gets confusing.

This page describes each product only by what its maker says it does, and links to the source.

## Side by side

| Question | Bid management platforms | Piper |
| --- | --- | --- |
| Main job | Run the bid: invite subs, distribute documents, collect bids, track coverage | Understand the bid: check each proposal against the project documents |
| What a bid is compared to | Other bids, line by line | The drawings, specifications, addenda and your company's scope standards |
| Silent exclusions (items a sub never mentions) | Depends on the bid form your team set up | Flagged, with the document line that requires the item |
| Traceability | Bid documents stored with the project | Every finding linked to the clause or sheet it came from |
| When the documents change | Re-issue to bidders | Shows which scopes and findings the change affects |
| Sub network and invitations | Core strength | Not a feature; keep using your platform |
| Output | Leveling view inside the platform | Export to the workbook your team already reviews |

## What the platforms say they do

- **Procore Bid Management** lets teams "distribute information, collect bids, and track coverage all in one place" ([Procore](https://www.procore.com/bid-management)).
- **BuildingConnected** (Autodesk) is preconstruction software that "streamlines bid and risk management" with what Autodesk calls the largest network of construction professionals ([BuildingConnected](https://www.buildingconnected.com/)).
- **PlanHub** is a construction bidding platform with bid management software for finding projects and managing bids ([PlanHub](https://planhub.com/)).

All three are strong at the part of preconstruction that is about people and logistics: who was invited, who responded, which trades are covered, and what each sub priced.

## What Piper does

Piper reads subcontractor proposals against the drawings, specifications, addenda, and your company's scope standards. It flags exclusions, qualifications and silent items, and links each one to the clause behind it, so a reviewer can check a finding without re-deriving it. The leveling then exports to the workbook your team already uses for the bid meeting.

The same project understanding feeds [scope generation](https://piper-ai.com/use-cases/scope-generation) before bids go out and [final bid review](https://piper-ai.com/use-cases/final-bid-review) before you submit, so a gap found at leveling is a gap you can trace back to the scope you sent.

## How teams use them together

1. **Solicit and collect in your platform.** Nothing about that changes.
2. **Bring the proposals into Piper** with the project documents.
3. **Level against the scope.** Review the gaps Piper found, each with its source.
4. **Decide and carry in your workbook.** The bid meeting runs on the sheet your team trusts.

## Which one do you need?

- **Only a platform** if your packages are simple, scopes rarely change after invite, and your pain is coverage and follow-up.
- **Only Piper** is rare: you still need a way to invite and collect bids, and email plus a shared folder is a platform too.
- **Both** if your losses come from scope a sub never priced: multi-trade packages, boundaries between trades, or addenda that land after bids go out.

## Where Piper fits

Piper does not replace your bid management platform. It answers the question the platform is not built to answer: does each bid actually cover the work in the documents? See it on [the bid leveling page](https://piper-ai.com/use-cases/bid-leveling).

### Is Piper an alternative to Procore or BuildingConnected?

Not for running the bid. Piper does not send invitations or manage a sub network. It is an alternative to leveling bids in a spreadsheet: it checks each proposal against the drawings and specs and links every gap to its source.

### Can Procore or BuildingConnected find scope gaps in a sub bid?

Their makers describe them as bid management tools: inviting subs, collecting bids and tracking coverage. Piper's approach is different: it reads the drawings and specs directly and checks each bid against them, so a gap the sub never mentions is still found.

### Do I need to change my bid management platform to use Piper?

No. Keep collecting bids where you do today, and bring the proposals and project documents into Piper for leveling.
