RIB Software is a pioneering enterprise, committed to driving innovation in the construction and real estate industries. We are the home of iTWO costX, an all-in-one BIM and 2D takeoff and estimating software solution first released from our Brisbane office in 2004. 

More than 15 years later, iTWO costX is the software of choice for quantity surveyors across Australia and in 90+ countries around the globe. More than 16,000 licences have been sold since the product’s initial launch, with different feature levels available to suit businesses large and small. Our other innovative products include iTWO benchmark, a fully-web based solution for quick and accurate benchmarking and conceptual estimating.

RIB is committed to educating the future generations of construction, so iTWO costX is available to quantity surveying students at universities in Australia and worldwide. 

Our enterprise was known as Exactal prior to June 2020, when we changed our brand and product identity to align clearly with our parent company RIB Software. iTWO costX and iTWO benchmark can be integrated within RIB Software’s iTWO and MTWO enterprise platforms, both of which help construction managers to take the next step through 5D BIM, big data and other next-generation technologies.

By adopting a proactive approach to cost management, Rawlinsons has made significant contributions to the Australian built environment since 1953. As the creators and editors of the extensively circulated Rawlinsons Australian Construction Handbook and Rawlinsons Construction Cost Guide, we maintain the most comprehensive and current library of construction pricing information and data sources in Australia.

Rawlhouse, our publishing company was formed with the express purpose of producing an annual book of technical building and construction costs which would include detailed information for all Australian states. The first edition of Rawlinsons Australian Construction Handbook was released in 1983 and has become the leading reference book within the construction industry in Australia. It is directed mainly at medium/large projects.

It later became obvious that there was a need to introduce a compact volume that would specifically meet the demands of those involved in the light industrial, small commercial, and housing sections of the industry. In 1993 Rawlinsons Construction Cost Guide was launched and became an instant success. This is an essential reference book for the small builder, architect/consultant, and many others in the construction industry.
