Burlington Canal Lift Bridge
PERI UP provides fast and cost-effective scaffolding solution to the time sensitive bridge restoration project
The historical Burlington Canal Lift Bridge in Burlington Ontario is getting a major facelift.
In December 2009 PERI was awarded the contract to provide access scaffolding for the first phase of the job, providing suspended access scaffold for the entire west side of bridge which is 114 metre long and 11 metre wide. PERI’s solution was the most cost effective among the bidders and was supported by detailed engineering design.
Some of the key project requirements included:
Because the lift bridge is a key cog in commercial trade for Burlington, Hamilton and much of southern Ontario the work must be completed during off-season shipping months so no impediment is caused to the marine traffic in the canal. The entire first phase must be completed in only 55 days. At the same time the bridge has to remain partially open to vehicular traffic over the bridge during restoration work. Considering the water body below the bridge the restoration work needs to be carried out with environment sensitivity, not allowing any potential hazardous material like the removed old paint escape the work area.
PERI Solution:
For scaffolding suspension at each section 2 MPB24-36 aluminum and 2MPB24-480s, spliced together and cantilevered 3 metre outside the bridge deck were used to transfer the scaffolding load to the bridge.
To suspend the scaffolding a DW15 tie was run between the MPB beams, and through PERI UP standards and secured at top and at bottom with PERI wing nuts. PERI design had enough flexibility to allow avoiding existing bridge trusses, guardrails and bracing.
The PERI UP standards were horizontally connected together using PERI UP UH 200 and UH 250 ledgers.
In response to environmental requirement of the project the entire 114 metre length of scaffolding around bridge deck was enclosed and sealed using layers of plywood and tarp.

“PERI equipment and engineering design for the Burlington Lift Bridge job outperformed all other scaffolding systems. We were quite impressed with the design PERI used for suspending the scaffolds.”
