Home > Caste Study > Custom Installation Case Study: Craning a Security Door into a High Rise

OverviewAfter-hours security for an open-concept office

For the Toronto branch of international marketing firm J Walter Thompson, a door was needed to provide after hours security for their office on the 11th floor of 160 Bloor Street. The otherwise open concept space was directly accessible from the elevator lobby.

This suite was part of a much larger project by international construction company Turner, which was in charge of overhauling six floors of the Bloor Street location according to designs by architecture firm HOK. Dynamic Closures was commissioned to create a custom security door for the space. Our partner, Dynamic Closures Ontario, handled the project management and execution for the entire door installation.

The doorA Lift Ready Portcullis that disappears into the ceiling

The door itself was not particularly challenging to construct. It was a Lift Ready Portcullis with a built-in electrical system to open and close the door at the push of a button. Additional sleeves on every rod added to the contemporary look, maintained consistent spacing for the rods, and provide a more substantial appearance.

The door is about 10 feet high, but coils away invisibly into a ceiling pocket when not in use.

The challengeGetting there is half the fun

This particular door would require some very special logistics for delivery, as it would not fit in any of the high rise’s freight elevators. Weighing about 800 pounds including the crate, it was too long and heavy to be simply carried up the stairs. The solution was to use a crane to lift the door through the 11th storey window to the installation site.

Lead time

City permits

Almost four weeks of lead time were needed to secure the necessary permits from the City of Toronto.

Traffic

Road closure

Authorization to close the road so the crane could be set up and operated safely on Bloor Street.

Lift

Mobile crane

A crane lifted the 800-pound crate from street level to the open 11th storey window.

Utilities

Hydro supervision

Personnel from the hydro company supervised the lift to ensure no damage to overhead wires.

Glazing

Window removal

A window glass company removed the window in advance and remained on standby to replace it once the craning operation was through.

Safety

Police supervision

Police supervision was needed for the entire five hours to redirect traffic and keep curious bystanders out of danger.

The big dayTwo days, one street, zero surprises

The craning operation began in the morning and was carried out seamlessly. From beginning to end, the installation took two days to execute, supervised by Gerry Dent of Dynamic Closures Ontario.

Step 1
Site prepared

The street was closed, the window removed and the crane set up. Lifting began on schedule.

Step 2
Crate lifted to the 11th floor

The crane raised the crated door from street level to the open window on the 11th floor, with hydro and police personnel supervising.

Step 3
Guided through the window

The installation team stepped in to guide the crate through the window and onto the electric lift that would maneuver the door into position.

Step 4
Door mounted

Once the door arrived at the location, mounting it was fairly easy, as all Dynamic Closures doors are designed for smooth installation.

We had done similar jobs before, but normally we don’t work at this kind of elevation, with the exception of our CN Tower project.

The resultA seamless part of the workplace environment

Today, the door is still rolling smoothly for the end users, and the employees can focus on their daily challenges without worrying about after hours security. They probably are not even aware of the level of effort it took to get their door into place.

While a craning operation is almost never needed for the installation of a security door, it is good to know that the team at Dynamic Closures Ontario has the expertise to handle a project of this magnitude. Whether your door or installation needs are simple or complex, Dynamic Closures can be relied on to deliver, even if we have to close an entire city street to do it!
