RIB Software AG announced they have signed a Phase I Agreement with Rezayat Group of Saudi Arabia to use the iTWO 5D Big Data platform for construction. Under this initial agreement, Rezayat will roll out iTWO 5D technology across the tendering divisions of their three independent Engineering & Construction groups, taking advantage of the iTWO 5D enhanced model-based QTO and estimating capabilities, bi-directional data exchange with their scheduling software, virtual 5D simulation, procurement and sub-contract management using e-tendering, and corporate standardization of their tendering data using iTWO's Big Data single source of truth database. At the completion of this first phase roll-out, Rezayat will then begin implementation of the iTWO 5D Technology for multi-project execution.
