J UNE 2017 | 65 natural light in controlled ways through the use of static and active shading systems, as well as strategically placed opaque portions of curtain wall. Other sustainable features of the project include 581 vertical geothermal wells (123-metres deep) that create an efficient heating and cooling system, in-floor radiant heating tubes and 5,000 square metres of skylights. EllisDon, the construction manager for the IFP, calls this one of the largest projects in the history of Alberta, doubling the size of Calgary's previous terminal space: "The five-level project consists of approximately 3,178,000 cubic feet of concrete and 8,000 tonnes of structural steel – 2,000 tonnes of which are architecturally exposed." Structural steel installation began in July 2012, with the material transported from Quebec. The IFP also included the extension of the existing departures roadway, an added parallel curbside roadway, a new waste handling facility and a podium structure for a 318-room in-terminal hotel (the structure and interior fitting of which was completed by EllisDon). EllisDon credits BIM software for demonstrating its value at the front end of the project with the installation and the integration of the precast support columns (Lafarge), structural steel (Supermétal), and curtain wall installations (Contract Glaziers) for the building envelope. Similarly, Justin Black, former BIM applications manager for AECOM, notes that his company modelled the mechanical engineering portion of the project (including life safety and IT infrastructure) in Revit BIM software using 30 different Revit models: "Our Revit models reflect not only communication across mechanical and electrical teams, but close collaboration with the external design team as well." Over 660 kilometres of in-floor radiant heat/cool tubing was installed as well as 1,300 metres of duct bank and 10 kilometres of cable tray, with AECOM's mechanical team working to incorporate HVAC and geothermal elements into a BIM model while its electrical team provided lighting, power, cable tray and duct bank modelling. Intense collaboration, advanced technology and ingenuity were required to finish IFP for a grand opening in October of 2016; however, unlike other prominent international airports that had experienced severe operational challenges on opening day, The Calgary Airport Authority conducted a soft opening of its facility five days prior to the official unveiling. "We went through a number of public trials, culminating in us accommodating a few airline arrivals and departures, in order to ensure that everything functioned as intended," says Humphries. Mejia summarizes the sentiments of everyone involved with the project by saying, "Between consultants and construction crews, over 2,000 people worked on this project, and the attention to detail was such that we even improved the road signage leading up to the facility. The result is that Alberta has a world-class international facility that everyone can be proud of."
