[ Mechanical estimating ]

Mechanical estimating software. Equipment, duct, and the bid after.

For mechanical trade estimators and preconstruction leads. HVAC and sheet metal. ArosBid includes takeoff and estimate and replaces Trimble AutoBid. Trimble Estimation MEP is the current Trimble MEP estimating product. Then the bid after those quantities exist.

ArosBid versus Trimble AutoBid.

Honest columns. AutoBid’s published job is takeoff and estimate. The other rows are stages ArosBid also runs. They are not an AutoBid defect list.

What you can check on a walkthrough.

Three claims that are architecture, not a pitch. None of them is a customer story we do not have.

  1. 01Takeoff is in the product

    ArosBid includes takeoff and estimate and replaces Trimble AutoBid. The walkthrough is the proof. This page does not invent a mechanical takeoff screen we have not shown you.

  2. 02The traps are in the documents

    A schedule that disagrees with the spec, tonnage or CFM that moved on the sheet, duct and piping that the takeoff missed, a controls boundary claimed by nobody. Those are readable before the bid goes out.

  3. 03Money is code

    Extensions, sums, reconciliations, and allowances run as integer cents. A language model does not price the chiller, the air handler, or the duct.

What people mean by mechanical estimating software

Mechanical estimating software is the HVAC and sheet-metal number. Not a general contractor bid board. Not a plan room. The invitation is already yours. The set is an equipment schedule, a spec that names a different tonnage, duct and piping, and a controls section that reads as somebody else’s work. The person who carries that number is a mechanical estimator or a preconstruction lead, not a GC pursuing coverage.

ArosBid includes takeoff and estimate and replaces Trimble AutoBid. That sentence is the estimating claim. Trimble Estimation MEP is the current Trimble MEP estimating product. If that is the name on a renewal, it is still the Trimble estimating aisle. The named comparison is ArosBid vs AutoBid. This page exists so “mechanical estimating software” lands on a trade desk, not a GC category.

The MEP hub is MEP estimating software. The trade page that stays specific — traps, sectors, the cited set — is mechanical. The role page is for estimators. The electrical ranking page is electrical estimating software. This URL does not replace those pages. It is the keyword they were already answering.

What mechanical bids miss

A duct takeoff that is light is checkable. A chiller that is 350 tons in the spec and 400 on drawing M-401 is equipment, duct, and power you already owe. CFM on the air handler that does not match the schedule changes the coil, the duct, and the power. Piping that the takeoff skipped because it lived on a detail, not the plan, is still pipe.

Startup and TAB excluded in the vendor fine print sit inside the spec’s expectation. The controls boundary claimed by nobody — Division 23 and Division 25 both pointing away — lands on whoever priced the equipment. A one-year warranty offered against a two-year requirement is a manufacturer line that never appeared on the quote.

Those are the misses. They live in the documents. The mechanical industry page cites them to drawing and section. This page names them so the search matches the desk. Air change rates on a hospital, CRAH counts on a data hall, process cooling in an appendix — those change the list before any count starts.

Empty conference table after hours. No screens.

What ArosBid runs on a mechanical desk

Intake recognizes the tender and opens the pursuit. Takeoff and estimate are included. Document review cites the equipment schedule, the spec, the duct and piping sheets, and the controls section to the page that proves them. Bid/no-bid is scored against your own GC history, not a hallway guess. Vendor RFQs go out as packages built from the reviewed set. Leveling reconciles every total and lifts exclusions out of the fine print. Budget lands in Excel. The proposal is assembled from decisions you actually recorded. Readiness checks bonding, addenda, and gates before you submit.

A human approves every send. During training, the mail connector will not release a send that does not cite a recorded decision. It learns the pattern you already signed off, then automates it. The approval gate does not move.

Walk those stages on the platform page. The process comparison against a manual desk is on Compare. Book the walkthrough at Book a live demo. Named pursuits in that walkthrough, including Riverside Office Tower, are fictional demo data and labeled as such. This page does not invent a customer, a logo, a win rate, or a savings percentage.

Money, instance, send authority

Every extension, sum, reconciliation, and allowance in ArosBid uses deterministic integer-cent code. No language model prices the job. The model’s job, where it has one, is reading: finding the table in a vendor PDF, locating the clause in the front end, matching an addendum to what was already priced. The instant numbers are extracted, they are handed to code.

Each customer gets an isolated instance: own database, own document store, own subdomain, Microsoft Entra ID. Customer bid data is not used to train public models. During training, nothing leaves without a recorded human approval.

If you want the named replacement page, use vs AutoBid. If you want the three-trade hub, use MEP estimating software. If you want the mechanical traps cited to sheet and spec, stay on industries/mechanical. Both URLs stay live.

Empty estimator office. Plans and a desk. No product chrome.

[ FAQ ]

Asked on the first call.

Does ArosBid replace Trimble AutoBid?

Yes. ArosBid includes takeoff and estimate and replaces Trimble AutoBid. That is the estimating seat. The rest of the product is the bid after those quantities exist.

What is Trimble Estimation MEP?

Trimble Estimation MEP is the current Trimble MEP estimating product. AutoBid is the seat many mechanical desks still name. This page is honest about both names. Replacement on this site is AutoBid, including takeoff and estimate.

Is this for general contractors?

No. This page is for mechanical trade estimators and preconstruction leads. A GC bid board is a different product. Procore, BuildingConnected, SmartBid, PlanHub, Dodge, and ConstructConnect are invite or document sources, not this seat.

How is this different from the mechanical industry page?

/industries/mechanical stays live. It is the trade desk: traps, sectors, the cited set. This URL is the ranking page for the search “mechanical estimating software.” They point at each other. Neither replaces the other.

Are the stills or named jobs on this page live work?

No. Photographs are cinematic location stills reused from existing ranking pages. Named pursuits in the walkthrough, including Riverside Office Tower, are fictional demo data and labeled as such.

Empty lobby corridor at night. No signage.
