Flared-Radiused Bridge Pier Formwork Construction


Massive Formwork Construction Project

EFCO is no stranger to massive formwork construction projects. EFCO first became involved in a part of the Calgary Ring Road construction in 2010 on the SE Stoney Trail project. At that time, EFCO provided PLATE GIRDER® formwork for constructing 27 bridge structures as part of the 25 km (about 15.53 mile), six-lane stretch of highway.

Now, 12 years later, EFCO is again involved in this truly monumental project.

Bridge Replacement Supports Increase in Travel

The last four projects that comprise the Calgary Ring Road are currently underway. When complete, they will support the highly anticipated increases in travelers and goods transported in and out of Alberta.

South Bow River Bridge Construction

The multi-year bridge construction project, called the South Bow River Bridge project, is located at the intersection of Stoney Trail SE and the Bow River. Stoney Trail SE is a major route impacted by the growth of Alberta. The $60 million South Bow River Bridge project is one of the last four projects that comprise the Calgary Ring Road.

Flared and Tapered Bullnose Bridge Pier Cap

PCL Construction Management, Inc. was awarded the South Bow River Bridge project in January 2021. A part of the project was widening the westbound bridge from three to four lanes and constructing a new eastbound bridge to accommodate four lanes of vehicle traffic. PCL worked closely with EFCO to engineer a formwork solution to shape the flared and tapered bullnose piers designed for the eastbound and westbound bridges. Both the eastbound and westbound bridges will accommodate a fifth lane in the future if needed. The project will also include a new standalone pedestrian bridge located to the south of the South Bow River Bridge.

EFCO Formwork Combination | Bullnose Pier Cap

EFCO engineers used the EFCO LITE® wall system in combination with the industry-leading PLATE GIRDER® formwork system to construct two bullnose piers necessary for the new eastbound bridge.

Flared/Radiused Bulkhead | Pier Formwork System

EFCO engineered, designed, and manufactured custom flared/radiused bulkheads to bolt onto standard PLATE GIRDER formwork panels. Since slight variations in elevation and length of the piers are required, EFCO developed a formwork solution that would minimize the amount of reconfiguration of the pier formwork to reduce labor, thereby reducing the overall cost of concrete. As planned, PCL re-used the same formwork solutions to construct piers to widen the westbound bridge. The Eastbound and Westbound structures were contracted separately, and each had dedicated formwork packages as well as dedicated custom forms.
