**Short answer:** Level mechanical and electrical bids against a scope sheet built from the specs, then check each bidder against the MEP items most often excluded: controls, fire alarm, temporary power, housekeeping pads, roof curbs, firestopping, test and balance, commissioning support, permits and utility fees. Plug every gap before comparing totals. Consight automates this for commercial general contractors and flags each exclusion on the scope line it affects.

## Key takeaways

- MEP packages are usually the largest and the riskiest to level.
- Most MEP [scope gaps](https://consight.ai/articles/how-to-find-scope-gaps-in-subcontractor-bids) sit at trade boundaries: between mechanical, electrical, controls, fire protection and the GC.
- Use a responsibility matrix for furnished-by and installed-by items.

## Why are MEP bids hard to level?

Mechanical, plumbing and electrical packages are large, written against long spec sections and full of boundary items that more than one trade could carry. Bidders protect themselves with long exclusion lists, and two bids with the same number can cover very different scope.

## Which MEP items are most often excluded?

| **Item**                                 | **Usually at risk between**         |
| ---------------------------------------- | ----------------------------------- |
| Building automation and controls         | Mechanical and controls contractor  |
| Fire alarm                               | Electrical and fire alarm vendor    |
| Temporary power and lighting             | Electrical and GC                   |
| Housekeeping pads and equipment supports | Mechanical, electrical and concrete |
| Roof curbs and penetrations              | Mechanical and roofing              |
| Firestopping                             | Every trade and the GC              |
| Test, adjust and balance                 | Mechanical and a TAB firm           |
| Trenching and backfill                   | Plumbing, electrical and sitework   |
| Cutting, patching and core drilling      | MEP trades and the GC               |
| Permits and utility company fees         | Subcontractors and owner            |
| Equipment furnished by others            | Owner, vendors and installers       |

## How do you level an MEP package step by step?

1. Build the scope sheet from the spec sections and drawings, including the boundary items above.
2. Create a furnished-by and installed-by matrix for equipment and controls.
3. Read every proposal’s exclusions and qualifications in full.
4. Mark each line included, not included or needs review for each bidder.
5. Plug every exclusion from your estimate or another bidder’s price.
6. Check equipment manufacturers and alternates against the specified basis of design.
7. Confirm every addendum was acknowledged.
8. Compare leveled totals and hold a scope review call with the top bidders.

## How does Consight help level MEP bids?

Consight reads each MEP proposal, maps it to your scope sheet and surfaces exclusions, alternates and qualifications on the line they affect. The estimator plugs missing scope so totals compare fairly, and every value links back to the proposal text. Large commercial GCs such as Clayco, Gray Construction, Alston Construction, W.M. Blanchard and NRP use Consight on their biggest trade packages. Read [how to compare subcontractor bids](https://consight.ai/articles/how-to-compare-subcontractor-bids).

## Frequently asked questions

### What is the most common scope gap in mechanical bids?

Controls. Mechanical bidders often exclude building automation or carry it only partly, and it is easy to miss until the controls contractor’s scope is bought out.

### What is the most common scope gap in electrical bids?

Fire alarm, temporary power and low-voltage systems are the most frequent exclusions, followed by trenching and equipment connections.

### Can AI level MEP bids?

Yes. Consight reads long MEP proposals and exclusion lists, maps them to the scope sheet and flags gaps for the estimator to review.
