McConnell Dowell Company Profile

The Mechanical Division has a unique ability to apply their steel fabrication knowledge and skills to the temporary works fabrications required for construction projects. This unique ability comes from working closely with our construction projects and in-house temporary works design team to understand the needs of the project team. The Mechanical Division have performed both simple and complex temporary works design including: • Standard Scaffold • Formwork (less than 1.2 m to over 3 m high) • Hoarding and fencing (less l.2 m high to 3 m high) Old Māngere Bridge Client: Waka Kotahi NZ Transport Agency The Mechanical Division have preformed the temporary works on the old Māngere Bridge Replacement project.
