RIB iTWO costX 7 R2 (5D BIM Takeoff & Estimating Software)

Overview of RIB iTWO costX 7 R2

RIB iTWO costX 7 R2 is professional estimating software developed by RIB, a global leader in construction technology . The platform combines advanced 2D takeoff and 3D/BIM quantification within a single environment, streamlining the estimation process from initial measurement to final reporting .

The software supports 5D BIM workflows, meaning it adds a cost dimension to 3D models to enable real-time cost updates when design changes occur . This approach helps construction professionals generate more accurate estimates, reduce errors, and win competitive bids.

RIB iTWO costX serves diverse construction roles, including commercial builders, subcontractors, quantity surveyors, and BIM managers . It processes multiple file formats, from vector-based CAD files to scanned drawings, making it adaptable across project types .

Key Features

RIB iTWO costX 7 R2 offers a comprehensive suite of features designed for professional estimating and quantity takeoff.

2D and 3D Quantity Takeoff

The software enables both manual and automatic takeoff from multiple sources, including BIM models, CAD files, PDFs, and scanned documents . This dual capability means estimators can work with traditional 2D drawings while also leveraging the efficiency of 3D model-based quantification.

The 2D takeoff tools provide precise measurement capabilities, while the 3D/BIM module extracts object properties and generates quantities automatically from models . The Model Tree allows filtering and navigation through model components, with transparent viewing modes to reveal hidden objects.

Live-Linked Estimating Spreadsheets

iTWO costX features live-linked estimating workbooks that update automatically when takeoff dimensions change . This dynamic connection eliminates manual data transfer between measurement and costing stages, reducing errors and saving time. The spreadsheets support multi-level cost breakdowns and extensive rate library integration.

5D BIM Functionality

As a 5D BIM software, iTWO costX adds cost as the fifth dimension to 3D models . When design changes occur, the cost implications update in real time, enabling better-informed decisions during preconstruction. This functionality helps teams manage budgets more effectively and reduces the risk of cost overruns.

Carbon Accounting

The software includes embodied carbon tracking features, allowing users to measure and report environmental impact . This capability supports sustainability goals and helps meet growing regulatory requirements around carbon reporting in construction.

Subcontractor Comparison and Reporting

iTWO costX enables multi-level cost breakdowns and subcontractor pricing comparisons . Professional reporting tools generate customized outputs, including bills of quantities and detailed cost plans. The software supports various reporting formats to suit different stakeholder needs.

Cloud and Network Deployment

The platform can be deployed in cloud or networked environments, enabling team collaboration across locations . Cloud functionality ensures project data remains accessible and synchronized across teams.
