The largest continuous concrete pour in B.C., outside the Lower Mainland, is underway in 91大黄鸭. 

Construction crews started setting up for the pour around 11 p.m. on April 27.

The 22-hour, 5,600 cubic-metre concrete pour on the University of B.C. Okanagan's downtown 91大黄鸭 campus project at 550 Doyle Avenue started around 1 a.m. on April 28. 

Doyle Avenue between Ellis and Bertram streets and a stretch of St. Paul Street between Bernard Avenue and Cawston Avenue are closed to vehicles while the pour takes place. Some sidewalks in the area are also closed to foot traffic. 

The project has stirred controversy in the city after four neighbouring buildings began deteriorating and were forced to evacuate due to ground shifting caused by the construction. Three of the buildings have since been demolished, while the fate of low-income apartment building Hadgraft Wilson Place on Bertram Street remains unknown at this time. 

A lawsuit was filed by residents of Hadgraft against UBC, the City of 91大黄鸭, and other parties involved in the construction of what will be 91大黄鸭's tallest tower once complete. UBC and the city have denied allegations of wrongdoing in response to the suit.
