The Most Complete Estimating Software Globally

Powerful cost estimating software which allows you to be more efficient, more accurate and win more profitable work

What is CostOS?

By combining traditional estimating methods with BIM 3D, 2D and GIS, CostOS is a powerful cost estimating software which allows you to be more efficient, more accurate and win more profitable work. From feasibility or Cost Plan through to the final detailed bid on a single platform.

CostOS is avaiable in three options: CLOUD – ENTERPRISE – STANDALONE


BIM & GIS Modules Regarding BIM, CostOS is truly ‘BIM enabled’

BIM technology has been at the heart of CostOS from the very start and is hence, seamlessly integrated and standard functionality. No links, no imports etc. – it’s part of the furniture.

This enables the measurement of quantities, directly from a BIM and in a very simple but visual way. Just navigate through the model, auto-select elements, associate them with database items (or create new ones), click go and produce a fully described, measured and priced Bill, directly from the model – from BIM to BILL to BID in a few easy steps.

This is because CostOS already stores the relationship between model classes and cost database items and as since open industry standard IFC files are utilized, CostOS BIM technology can be used, regardless of the BIM designing tool used to create the model.


With CostOS BIM technology, it really is a case of ‘what you see is what you estimate’. As model elements are selected and measured, CostOS  ensures that no item is missed.

Furthermore, CostOS’ powerful parametric engine, if combined with BIM, enables the quick and accurate pricing of ‘less than fully-detailed’ BIM models.  Moreover, it allows design optimization and quick identification of most appropriate materials and construction methods. Intelligent, parameter-driven assemblies can be built and applied to BIM elements

2D Takeoff Modules

CostOS 2D Extraction

CostOS 2D Extraction, is a Nomitech branded Quantity Takeoff Module that is integrated with CostOS Estimating. The key Features of CostOS 2D are:
Supports measurements on PDF, TIFF, JPEG, DWG, DGN and DXF drawings

  • It is multi-user and enables many Quantity Surveyors working on the same Projects
  • It produces an analytical document of the measurements, including the calculations performed (either split in Triangles or in Basic Shapes)
  • It Supports the definition of custom measurements, such as ducts area, slab rebar and any measurement that the QS can think of
  • The quantities are fully synchronized with the BOQ / Estimate
  • The quantities can be associated with CostOS Parametric Models / Smart Assemblies.

On-Screen Takeoff by On Center

Apart from CostOS 2D, CostOS Estimating is also integrated with On-Screen Takeoff from On Center Software.


Sectors Multi-Discipline Estimating

Architecture, Engineering, Construction

If you are a General Contractor, Subcontractor, Consultant, QS or Project Owner, then CostOS is the only Estimating and Quantity Takeoff Solution you will ever need.

Oil & Gas

Oil & Gas projects can be extremely demanding when it comes to estimating. Estimators often have to provide costs and budgets with continuously evolving scope and within limited timescales.

Engineering, Procurement, Construction

Price thousands of items and manage a substantial amount of data with unmatched ease. Import/ Export or Copy/ Paste quickly, huge equipment lists and manage their Revisions easily. Group, sort, filter the data and get Costs, Man-hours, Escalations etc. in any way that you need.
