Project involved part of the polypropylene petrochemical complex in Strathcona county in Aberta, Canada.

The entire plant was designed to convert low-cost extracted propane to 525,000 tons a year of polypropylene. This, a thermoplastic polymer of high value and easy transport, is used in the production of a wide range of finished and commonly used products, such as doormats and colanders. The construction of the complex began in 2018 and its completion is scheduled for the end of 2021.

Consisting of a propane dehydrogenation plant (PHD) and a polypropylene (PP) plant, the petrochemical complex will cost approximately $ 3.5 billion. The PHD plant project involves the conversion of approximately 22,000 barrels of propane per day into 525,000 tons per year of polymer grade propylene.

Our activity in both the design and construction of the petrochemical complex has involved the BIM implementation of the HVAC plant building project of the PP plant. The use of BIM has allowed to the final customer and the General Contractor to digitize geometric-informative data of the project, simplifying the control and management of the building in its different phases: from the design concept to the construction moment, from the commissioning and start-up to the management and maintenance for the entire life cycle.


The design of the HVAC systems for the petrochemical complex has required multidisciplinary skills and capabilities, embracing both plant engineering and civil works, reinforced concrete, steel and prefabricated structures. The knowledge of the elements proper to interdisciplinary engineering has allowed us to interface more quickly with foreign designers, collaborating on a single BIM platform. In addition to the models, over 200 project documents were delivered, the basis for the production of documents and equipment by the sub-contractors and contractors of the complex.

In addition to the geometric information relating to the overall dimensions and the different types of material, the BIM model has allowed subsequent analyses relating to the pressure drops and air velocity, with the consequent sizing both of the portions of ducts in manufacturing parts, and of the supports directly connected to steel and reinforced concrete structures, designed by various teams.

Furthermore, the BIM model has allowed us to conduct performance analyses of the entire plant system divided into its individual areas and environments, with the aim of improving energy expenditure during the period and taking into account the temperature changes proper of the area of Canada.
