The Power of iTWO: Automating Precision in Construction Estimation

Sharvari A. Mahajan

Abstract: The construction industry is continuously evolving through the adoption of digital technologies that enhance accuracy, efficiency, and decision-making. One such innovation is the iTWO software, a 5D BIM-based estimation and project management tool developed by RIB Software. This research paper focuses on the application and functionality of iTWO in the field of estimation and costing within construction projects. The study is based on my internship experience with a Belgium-based company, where iTWO is extensively used for both manual and model-based estimations. The software integrates cost databases for materials, labor, and equipment, which are frequently updated in accordance with market rates. Estimation in iTWO is carried out through the creation of recipes?structured activity templates containing variables and formulas that determine total cost, resource requirements, and efficiency. For model-based estimation, iTWO enables direct quantity take-off from BIM models by linking element attributes with predefined articles, resulting in highly accurate and rapid cost computation. The findings of this paper highlight how iTWO enhances estimation accuracy, minimizes human error, improves cost transparency, and significantly reduces the time required for quantity and cost calculations.
