Angus L. MacDonald Bridge Survey, Halifax

Allnorth was retained by Buckland & Taylor for Halifax Harbour Bridges to provide precision surveying services for the $200-million re-decking of the MacDonald bridge in Nova Scotia. The survey was required to establish the as-built shape of the structure for structural modeling including the towers, main cables, vertical hangers and deck profile. All survey work was completed at night in very short working windows when the bridge was closed. Tolerances were extremely tight with most measurements requiring 3mm repeatability. Steel temperature at 32 locations around the bridge was also monitored and recorded for use in the structural analysis. With up to 25 surveyors on site, our team provided precision surveying and engineering services for the 56 year old structure.
