project, the latest BIM models now integrate the fourth

dimension: time. This allows planners to properly schedule

each of the individual works to be carried out during

construction, anticipating roadblocks and conflicts that

might result in costly delays. “By sequencing those trades in

the most optimal manner, you can actually reduce the time

it takes to build a building,” Wash says.

“KONE is working with architects on next-generation

toolboxes that have innovative BIM models at their core

to not only let them understand the future capabilities of

our elevators, which are getting more sophisticated and

smarter, but also how to actually construct the building,”

he adds.

A high-profile example of this cooperation is One Bloor,

a 70-story, mixed-use retail and residential building in the

heart of Toronto. KONE provided the elevator ‘objects’ used

in the BIM model. “We used BIM with the contractor to

accelerate the design and the sequencing of the trades,”

Wash says.

Meanwhile, the building process is also getting a boost

from smart innovations like KONE UltraRope (a carbon-fiber

elevator rope that replaces the steel rope traditionally used

for elevators) and KONE JumpLift (a construction elevator

that uses the building’s internal hoist and runs at speeds

that are two to three times that of an old-fashioned outside

hoist). For tall buildings in particular, these innovations can

lead to substantial energy savings from eliminating tons of

steel from the load equation, and productivity gains of one

to two hours per worker per day, as personnel won’t be

waiting so long for a ride.
