Housing and Multi-Storey Buildings

Calgary Cancer Centre, Calgary, Canada

A total of 14 different, perfectly coordinated PERI system solutions are in use at the construction site of the Calgary Cancer Centre, providing support to the construction workers on site.
The different storey heights, ranging from around 4 to 7 m, posed a significant challenge to the planning and design team.
Over the course of this large project, a total of more than 15,000 m² of slab formwork will be used – including the SKYDECK system for construction of the underground garage.
In around 400 assembly and overview drawings, 218 different SKYTABLE designs have been created and tailored to the specific requirements of the construction site.
Due to the sheer size of the slab tables and the restricted space at the construction site, the SKYTABLE slab tables were assembled off site and delivered just-in-time – not only did this cut costs, it also cut down on the amount of space that was required.
The state-of-the-art VRB solution can be found at two locations on the construction site and is the culmination of the planning phase carried out conjointly by PERI and PCL Construction.
The VRB heavy-duty truss girders are assembled to create truss girder packages with platform units and extend from the building by around 9 m from level 4 upwards.
Another achievement: This project marks the first time that TRIO TRS 120 columns have been sold. As such, they have now been used successfully in the field since 2018.

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

Requirements

  • 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

Customer

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
