From the start, the construction team faced the challenge of performing site work and placing concrete in sub-zero temperatures. Through detailed planning and work sequencing, Cianbro used a Lean construction approach to create an efficient workflow. In addition to working on a tight project site with limited laydown, Cianbro operated directly abutting another construction firm that was performing work next door. This required Cianbro to coordinate and communicate work activities with the abutting project team as well as develop a detailed logistics plan.
