BF74397 Strengthening of Timber Substructure for BLE


GeoMetrix was retained by Mammoet Canada to perform a Bridge Load Feasibility Study for a Splitter Permit Load Transported on Bunked 4- File 26 Line Conventional Scheuerle Configuration Crossing Nine Bridges on the Transport Route between Edmonton, AB and Redwater, AB. From this load evaluation it was found that the Namepi Creek Bridge on Highway 29, at Radway (BF74397) required strengthening for the load. The Namepi bridge consist of 6.0 – 10.0 – 6.0, Type SM (prestressed concrete box girder) simple spans with a 13.8m clear roadway. The girders are supported on timber piles supporting timber seats at the piers, and timber piles supporting timber seats at the abutments. GeoMetrix designed a truss diaphragm system to brace the existing timber bents and reinforce the structure for the proposed permit loading. The truss system was used to connect the timber piles so they behave more rigidly as a unit for sharing the load across the entire bent system.
