Project Simulation Consulting

Project Simulation Consulting (Pty) Ltd (aka PSC) is an entirely separate business entity to Treo and has existed primarily to sell Metsim software, to provide training and technical support to its clients and simulation engineering consultancy services. It provides the same for Powerproject.

PSC was instrumental to Treo’s startup. Given the history between the two companies and nature of Treo’s project portfolio, synergies exist between the two companies in that clients who have engaged PSC for simulation engineering project support to progress projects beyond feasibility have also engaged Treo to assist with project engineering, procurement and construction consultancy services.


Metsim originated as a metallurgical process simulation program, written to perform mass balances around the major unit operations of complex process flowsheets. Application of the program proved so successful that it was expanded to include detailed heat balances, chemistry, process controls, equipment sizing, cost estimation, and process analysis. The unique nature of the programming language, APL, allows modification and expansion of the system with minimum effort and permits the incorporation of continuing technological innovations in process simulation.


Powerproject is a powerful, project, portfolio and resource management solution designed to support the way construction planners work and has evolved with their input so that it specifically meets the needs of the industry. Used by large and small businesses alike, it is the preferred software of thousands of construction professionals.

Powerproject has been used on some of the world’s most complex construction projects including: Europe’s tallest building, The Shard; The Reichstag in Berlin; Banora Point Highway in Australia; Durban International Airport and the rebuilding of Christchurch New Zealand.
