The £80.11m collaborative construction project V&A Museum of Design, Dundee comprises 2240m³ of double curved concrete walls which overhang the River Tay like a ship, the structure itself becoming a part of the art it is intended to enclose.
We explore the temporary works design challenges presented by the complex geometry of this unique building.
The curved reinforced concrete external walls of varying thickness are tied to central cores by a combination of steelwork and concrete floor slabs. The walls were only fully restrained when the floor slabs, steelwork and roof diaphragm were installed; meaning the walls required to be supported in the temporary case throughout the 18-month construction cycle until these elements were in place.
In a work of innovation, AWD transformed the existing falsework system that was used to cast the concrete walls into a bespoke temporary propping system to restrain the curved walls and steelwork, maintaining the integrity of the inclined angles and overhanging walls until the additional permanent supports were installed. However, the existing falsework system was only designed to resist the fresh concrete loads; not the cumulative concrete self-weight or applied floor slab and roof steelwork forces.
We look at the extensive analysis carried out to identify the additional forces from the concrete and steel which resulted in overloaded members in the falsework system, and the design of strengthening members to complete the transformation of the falsework system. Over the course of a year AWD assessed 21 reinforced concrete walls, completing over 70 individual design calculations and over 100 strengthening drawings. These design checks allowed 11,343 square metres of falsework to support 2,240 cubic metres of concrete and steelwork forces in the temporary condition until the roof diaphragm was completed.
We also look at the benefits of upcycling existing frameworks using as much proprietary equipment as possible to reduce the requirement for bespoke fabricated elements, saving additional cost and time, as well as reducing environmental impact.

Malachy began his career at AWD in 2009, after graduating from the University of Dundee. He became a chartered member of the Institution of Civil Engineers in 2014 and became AWD Managing Director in 2015. In over eight years with AWD, Malachy has built extensive experience in all aspects of temporary works, access engineering and structural design.
Under Malachy's stewardship, AWD have twice been shortlisted finalists for the Temporary Works Award at the British Construction Industry Awards in 2016 & 2017. Their collaborative work on V&A Dundee earned Highly Commended at the Concrete Society Awards in 2017, and their suspended access platform design for CenterParcs Longleat won the Construction New Index 'Project of the Year' accolade, also in 2017.
Malachy is a BSI Committee Member for the Structural Use of Aluminium, STEM ambassador and a prominent member of the Temporary Works Forum. He is also a Supervising Civil Engineer approved to administer ICE accredited training schemes.
