PCL Constructors Inc. is a group of independent construction companies which carry out full design-build, general contracting, and construction management services in three main sectors: buildings, civil infrastructure, and heavy industrial markets. Together, these companies have an annual construction volume of more than $6 billion, making them the largest contracting organization in Canada. One of PCL Constructors Inc. more recent projects was the design and construction of a spiral staircase for the Regina Research Park Building atrium. The PCL Regina team’s original staircase design included primarily structural steel materials, but they later decided to take concrete into consideration.Regina Research Park Building Atrium Stairs
