CostX® was first released in July 2004, as a way to integrate the estimating process with CAD drawing files. Although there were a few programs in this field at the time, our approach differed from others by the way we directly tied measurements to the elements in the CAD drawings. This approach allowed us to deliver unique bi-directional links between the estimate and the sections of the drawing represented. In June 2020, the product was rebranded to be called iTWO costX® to align more clearly with the rest of the RIB software range. iTWO costX® is now in wide spread use amongst quantity surveying, construction, development, subcontracting and estimating firms, both large and small, around the world. From its first release, iTWO costX® sales have grown exponentially and it is now sold and supported in over 90 countries including the UK, Ireland, Australia, USA, UAE, Malaysia, Singapore, China, New Zealand and across Africa.
