Princess Margaret Bridge, Fredericton NB, Canada
The refurbishing of a 2-lane 1km long bridge with 17 spans crossing the St. John River.
The bridge is constructed as steel truss structure with a navigation clearance of 25.6 m in centre
To win this infrastructure project, the contractor needed a scaffolding system and deck platform that would allow them to economically and safely cover the entire 1km bridge length. The contractor chose HI-LITE Aluminum Beams, Aluminum Decks and System Scaffolding Solution.
HI-LITE’s high-strength and light weight systems allowed the contractor to reduce labour and save time and money. Made from High Grade Structural Aluminum 6351- T6, HI-LITE Aluminum Beams could be spaced 24” apart for a 10’ span and could still withstand a 75 PSF load with safety factor of 4:1. This required less product than Aluminum Beams made by other companies using weaker Aluminum 6061-T6, and less labour to erect, move and dismantle.
HI-LITE also provided a complete System Scaffolding solution – standards, ledgers, ladders, clamps etc. that satisfied all the CSA & NB DOT requirement for bridges. HI-LITE 7’ and 10’ Aluminum Decks (100 PSF and 75 PSF) were used to withstand man and material load as specified by the CSA Code – maintaining a safety factor of 4:1. The decks are light,easy to assemble and work seamlessly with the System Scaffolding Solution.
