Doria, Inc. teams in New York City rigged a special double-tier swing stage and temporary monorail rig for a two-building loft conversion and addition project located in the DUMBO, Brooklyn Historic District. The two interconnected century-old buildings once served as a paint factory and distribution center dating back to the late 1800s.
To reface the taller building, GRFC panels needed to be carefully set in place in its façade. However, clear ground access did not exist on a portion of the building where it rose above the shorter adjacent structure. Additionally, the GRFC panels were too large to fit inside the regular elevator. Together with Sky Climber, LLC, Doria, Inc. came up with an alternative solution to set the glass in place.
The solution included Sky Climber temporary monorail and a 2-tier Sky Stage Ultra swing stage with dual line LNX Hoist motors. The unitized GRFC panels for the top floors and bulkhead areas required a double crew to pick and set the load in the top and bottom brackets.
The double-tier configuration and temporary monorail allowed crews to do exactly that. Hoists raised the ground-launched double-tier into place along the unimpeded façades for placement of the GRFC panels. Along the façade wall with limited ground-launch area, the platforms were hoisted into place and then trolleyed horizontally to reach otherwise inaccessible surfaces.
This solution is ideal for installing glass, curtain wall panels, or GRFC panels, allowing crews to span longer widths with smaller crews in situations where ground access is limited.
