DENVER (CBS4) – A crane equipped with special suction cups was used at the Denver Art Museum this month to install more than 50 glass panels on a new welcome center. The milestone comes in the midst of a $150 million renovation project which is expected to be completed in 2021.

Work crews used the crane to lay the panels out in such a way that they’ll make up what will be the “first structural glass wall facade of this size and scale in North America to hold itself up without the need for intermediate framing,” according to DAM.

“This facade is made up of elliptical concave curved glass panels,” said DAM deputy director Andrea Kalivas Fulton in a prepared statement. “They’ve never been used before in this way on a building.”

It will serve as a gateway between the museum’s Frederic C. Hamilton Building and the North Building, which is being modernized for future visitors as part of the project.

Currently the Frederic C. Hamilton Building is the only area of the museum that’s open to visitors.

The project is expected to be complete in time for the North Building’s 50th anniversary.
