Calgary Cancer Centre, Calgary, Canada

Project data

Location: Calgary, Canada

  • Construction of the Calgary Cancer Centre, a state-of-the-art cancer treatment and research centre in Calgary, Canada
  • In terms of the volume of material on site, the largest construction project PERI has ever taken on
  • Complex building structure covering a total area of around 185,000 m2 with varying storey heights
  • A total of 18 storeys, 5 of them below ground level and 13 above ground
  • Unusual shape of the building: A child and an adult embracing each other and breathing as one
  • Scheduled for completion in 2023


  • An efficient and safe formwork and scaffolding solution in order to realise the complex design of the building
  • Storey heights varying between 4 and 7 m
  • Cantilever from level 4 upwards, which extends from the building by about 9 m
  • Consideration of the restricted assembly space on site


PCL Construction Management Inc.

Customer's benefit

  • A complex formwork and scaffolding solution from a single source
  • A flexible slab formwork solution that can also be used to create varying storey heights and cantilevers
  • Optimal coordination, execution and logistics thanks to planning phase carried out conjointly with the client
  • Efficient work procedures and training of construction site personnel using 3D models and 4D timetables
  • Just-in-time delivery of material in order to cut costs and account for the limited amount of space available

PERI solution

  • A combination of 14 different PERI system solutions with more than 15,000 m2 of slab formwork, 4,000 m2 of wall formwork, a complex VRB solution and extensive scaffolding material
  • Use of the SKYDECK slab formwork to construct the underground garage
  • The most complex SKYTABLE project structure ever implemented to form the above-ground portion of the building: A total of 247 SKYTABLE slab tables involving 218 different designs
  • Just-in-time delivery of pre-assembled slab tables and subsequent erection using pre-assembled girders
  • VRB solution to create the cantilever: 36 VRB girders with a length of 22 m assembled to form 18 truss girder packages with platform units to enable casting of the slab above
  • The first time that TRIO TRS 120 columns have ever been used. These are used in conjunction with the TRIO TRS 90 columns
  • Construction site support through development of a 3D model and 4D timetable
