CostOS by Nomitech
CostOS by Nomitech is an enterprise cost estimating platform that links quantity takeoff from IFC and native BIM files, 2D CAD, GIS, and spreadsheets into one estimating workspace with optional cloud or on-premises hosting.
Large tenders still die when quantities live in one silo, rates in another, and the BIM model never feeds the BOQ. CostOS is built for that gap: you can host it in your own cloud tenant or on premises, then drive estimates from GIS, PDF, 2D CAD, and BIM sources while keeping teams on concurrent or named licenses.
The product emphasizes parametric assemblies, multi-user estimating rooms, and connectors into ERP and project controls so budgets, variations, and resource-loaded schedules can move without retyping. Nomitech also positions carbon-related outputs and PAS 2050 style reporting as part of the same stack for owners who need embodied carbon alongside price.
Public pages do not publish list prices; sales quotes cover packaging, database subscriptions such as RSMeans or Spon's where you opt in, and annual maintenance that bundles upgrades and ticketing support. Expect a formal demo path before numbers land on paper.

Pros and cons
Pros
- Explicit support for IFC and multiple native BIM authoring formats in quantity workflows.
- Flexible deployment on major clouds or self-hosted environments for regulated sectors.
- Deep catalog of optional third-party cost libraries for international work.
Cons
- No public price list; procurement needs a scoped quote and typically annual maintenance.
- Enterprise depth means implementation time compared with lightweight spreadsheet add-ons.
- Carbon and AI related claims require your team to validate scope against each contract.
Key features
BIM-linked quantities: Measure from IFC open standards and native BIM formats, then map model elements to assemblies and estimate lines for 4D and 5D style workflows.
Parametric assemblies: Reuse priced assemblies across projects and tie intelligence to BIM elements for faster option studies.
GIS and 2D takeoff: Pull lengths and areas from GIS maps, PDF drawings, and CAD files when models are not the source of truth.
Collaboration and roles: Multi-user access with permissions suited to large estimating departments working one live job book.
ERP and controls integration: CostOS Integrator connects to common ERP, CRM, and cost management stacks so published budgets stay aligned with finance.
External cost libraries: Optional subscriptions to commercial libraries such as RSMeans, Richardson, Spon's, BCIS, and region-specific datasets referenced on the vendor site.

Frequently asked questions
How much does CostOS cost per seat?
Nomitech does not publish standard seat prices on the marketing site. Licensing is sold as named or concurrent entitlements with annual maintenance that covers upgrades and support tickets. Budgeting teams should request a formal quote and clarify whether external data libraries are bundled or billed separately.
Can CostOS run on Azure, AWS, or only on our own servers?
The vendor states you may self-host or deploy on Oracle Cloud Infrastructure, Microsoft Azure, Amazon AWS, or LoadSpring managed hosting. That range matters for IT groups that must keep data in an approved region or network zone.
Which BIM and CAD formats can feed quantities into CostOS?
Marketing copy references IFC open standards alongside native BIM formats from common authoring platforms such as Revit, Archicad, Bentley, and DDS style systems. Quantities can also come from spreadsheets, PDF, 2D CAD, and GIS layers when those sources drive the work breakdown.
What is the difference between named and concurrent CostOS licenses?
A named license stays reserved for one individual, while concurrent licenses cap simultaneous sessions across a pool of users. Picking the model affects peak bid-week staffing versus baseline headcount, and the vendor FAQ calls both options out explicitly.
How does CostOS compare with estimating entirely in Excel?
Excel trackers fragment version control once multiple disciplines edit rates. CostOS centralizes model-linked quantities, parametric assemblies, and ERP-ready exports so the same controlled dataset backs bids, revisions, and downstream controls instead of copy-paste chains.
Who typically buys CostOS in construction and infrastructure?
Case studies on the vendor site include major contractors, specialist consultancies, and owner-side estimating groups in construction, EPC, utilities, mining, and nuclear programs. The positioning targets organizations that need multi-user bid rooms and large libraries rather than one-off residential spreadsheets.
