It will be mid-April before a giant crane is removed from the L Tower condo, the building's developer said.

The crane — still standing years after it was erected — remains attached to the 58-storey curving glass tower at the intersection of Yonge Street and The Esplanade as crews install a permanent window-washing platform.

The crane is just one source of frustration for building residents, many of whom paid more than $450,000 for a unit in the building, as construction is now 18 months behind schedule.

"It's just sitting there," resident Ali Mashayehki told CBC News.

"I can't imagine not seeing the crane when I drive on the Gardiner … it's part of the eye-line of Toronto now," he added.

Inside the building, Mashayehki said, amenities like the pool are still unfinished while others, like the gym, have just opened. The city is also eager for the crane to come down, as it's built on public space.

Alfredo Romano, president of Castlepoint Numa, one of the building's developers, attributed the construction complications to the building's distinct architecture, which was designed by Daniel Libeskind, the high-profile architect who also designed the Royal Ontario Museum's crystal addition.

"It's a very unique and iconic design," Romano said, adding the work must be done safely and properly.

Last June, Ontario's Ministry of Labour received a complaint about the construction of a second, smaller crane atop the building and issued a stop work order after investigating. The ministry issued two orders relating to "personal protective equipment" at the site, and also made four requirements for developers to turn over engineering reports, a spokesperson said.

Work has since resumed on the project under a new subcontractor, the developers said.

On Monday, workers could be seen on the washing platform near the top of the building.  

'Please be patient' developer says amid delays

Mashayehki said he's not sure whether he believes the developer's pledge that the crane will come down this spring. 

"They said in August that it's coming down in a month," he said, shrugging.

In 2014, EN Consulting — the group managing the L Tower Construction website, which provides weekly updates about the project primarily for stakeholders and those living in the St. Lawrence Market area — said the crane was set to come down in the first quarter of 2015.

By October, 2015, the website said the crane's removal is "tentatively scheduled" for November.

Romano said he understands residents are eager to be rid of the crane.

"We ask them to please be patient," he said.

Construction began on the L Tower in late 2009.
