Please join us for an evening panel discussion where members of our structures team will present on the technical and practical aspects of their involvement in construction disputes. We will highlight four key phases of the structural engineering expert’s role, and hope to foster a lively discussion of how and why structural engineering advice and evidence can be used in a dispute context.

  • Analyse: the role of the structural engineer
  • Communicate: turning complex ideas into clear, concise reporting
  • Articulate: the challenges of joint meetings and cross examination for an engineer
  • Collaborate: a speaker from HKA’s delay team discusses the value of technical input
