MTE's Involvement
MTE provided surveying services for the development and construction of the Fairway Bridge.
MTE’s scope of work included layout of 2 km of road, a culvert crossing Randal Creek and two roundabouts. The bridge decks spans 247 m of land and water and is 20 m above the river. The method for building this bridge was also unique in that construction began simultaneously at each end of the bridge, until they eventually met in the middle.
MTE played a pivotal role in this construction method by laying out all the critical components and providing the bridge’s engineer with strict measurements of the horizontal and vertical elevations. This was essential for ensuring that the two sections joined together correctly in the middle. MTE’s survey team used survey grade GPS for control establishment and some of the layout on the roads. A high precision total station and digital level were used to layout and collect precise information on the bridge. This was necessary due to the tight design tolerance. With this equipment MTE was able to constantly measure horizontally and vertically to the millimeter.
