Situated in the heart of downtown Calgary, the
41-year-old building underwent a complete renewal that saw concurrent upgrades
to all 23 floors, including renovation of the lobby and 388 guestrooms, and the
addition of a new VIP lounge, the M Club Lounge, the first of its kind for
Marriott in Canada.
The transformation also included new comfort spaces to
enhance the guest experience: a luxurious lobby where guests can work, relax,
and socialize; a state-of-the-art fitness center; an expanded conference and
business center; and ONE18 EMPIRE, Calgary's newest dining and bar hot spot.
A Concrete Solution
Marriott wanted to create additional guestrooms on the
23rd floor by splitting existing two-story rooms into single-story rooms. To do
this, a concrete slab needed to be added between the two stories; this is rare
in an existing building, and more so in an occupied building.
Typically, when pouring a suspended concrete slab,
reshore posts (support posts) would be added below the upper floor being
poured. The posts distribute the load between the two levels and support the
formwork (temporary mold) that holds the concrete while it sets. The reshore posts
rest on the existing structure below, which in this case would have been the 22nd-floor
concrete slab. This was not an option because hotel guests occupied rooms on
To provide a proper engineering solution without
disrupting guests, PCL designed a formwork system that the building’s existing concrete columns could support.
It was composed of wooden joists, steel beams, and steel support brackets
anchored to the concrete columns.
Expanded Scope, Accelerated Schedule
What started as a guestroom refresh, expected to take
eight months to complete, soon expanded into the client’s vision for a full hotel
renovation. And although the scope of the work increased by 40 percent, the completion
date couldn’t change because the hotel was fully booked for summer events,
including the world-renowned Calgary Stampede. This meant that more than a year
of work needed to be compressed within the original eight-month timeline.
With a firm end date, the project team focused on
re-phasing the project and ramping up recruitment. The team added 75,000 hours of labor
and 100 tradespeople to get the newly expanded job done right and on time, nearly
doubling the original number of workers.
PCL’s access to reliable, experienced craft personnel in
the Calgary area meant the team was able to quickly mobilize skilled PCL workers
to self-perform the finished carpentry, millwork installation, and other specialized
finishes. Hour-by-hour task scheduling kept the project rolling at a fast pace,
and the team cut completion time for each hotel floor in half, from fourteen to
