Self erector serves residential project

24 September 2020

Quasius Construction deployed a Potain Igo T 85 A self-erecting tower crane to build the 7 Penn Apartments complex in Wisconsin, USA, on a bustling street corner.

The contractor increased efficiency on the job site by replacing multiple pieces of construction equipment with the self erecting tower crane

“Pennsylvania Avenue is a significant road for residents who want to access the lake or riverfront area, so it was essential to minimise public disruption as well as the additional project cost and downtime that road closures would entail,” said Matt Noordyk, director of field operations, Quasius Construction. “The Igo T 85 A gave us the small footprint, easy setup and long reach necessary for job site efficiency.”

Quasius used the 6.6 U.S. ton (6 tonne) capacity crane to build the apartment building from the ground up, including prefabricated walls, ceiling trusses, flooring, roofing materials and f-frame steel decks. The five-storey, multi-family apartment complex will provide 66 homes, along with 92 underground parking spaces and 8,100 square feet (750 square metres) of commercial space, helping to address the area’s housing needs.

The small size and constrained location of the job site would have required partial street shutdowns for a crawler or mobile crane to build the property. However, the Igo T 85 A was capable of reaching the entire job site from a single location while only needing a small base footprint, the company said. Also operating fully from electric motors, the Igo T 85 A self erecting crane’s quiet operation also proved advantageous for the residential project.

The crane’s small footprint and long jib reach completed the job more efficiently without street closures, driving down project cost and simplifying onsite logistics

Quasius Construction positioned the Igo T 85 A on the west side of the building from where its 147.6 foot (45 metre) maximum jib radius covered the entire job site. The crane is operated via radio remote control, enabling improved job site communication and visibility across the site by the operator.
