Questions & Answers

Derek Nelson is a chartered quantity surveyor and a chartered engineering surveyor with 38 years of construction programming, cost and contract management experience. He is an accredited and certified expert witness; fellow of the Academy of Experts and the Royal Institution of Chartered Surveyors; and an accredited mediator and expert determiner. Derek authored chapter 17, “Disruption To Progress And Lost Productivity”, of Delay and Disruption in Construction Contracts (fifth edition, first supplement).

What attracted you to a career as an expert witness?

As a commercial manager with a large contracting organisation, I inherited a number of projects with disputes in arbitration. That experience led me to complete an LLM in construction law, with a view to enhancing my understanding and bridging a divide between the technical, commercial and legal aspects of projects. My first expert appointment was before the Scottish courts in 1998, to independently vouch for construction costs attached to a golf resort. In retrospect, I was astonishingly naive as to what was involved and what was expected when I agreed to do that. It was a steep learning curve. That said, they were definitely “gentler times” for experts.

The “attraction”, if that is the appropriate word, lies in the challenge and forensic nature of the role, while objectively bringing my professional experience and understanding to bear, with a view to assisting the tribunal in their determination of the dispute before them.

In all of that, I am very conscious of the need to maintain a balance of professional practice to ensure that my core competences remain current, and do not become out of date – as is the risk for some career experts. 

What do you enjoy most about working on construction matters?

The first 20 years of my career were spent on site helping to deliver construction projects. Before that I would work with my father on building sites during school holidays, etc. Combining that practical project experience with my professional qualifications as a chartered quantity surveyor and commercial manager, to successfully influence the outcome of a project, is immensely satisfying. Driving past certain projects still elicits the proud statement, “I worked on that!”

No two construction projects are the same and they each face their own challenges and issues. That keeps it both fresh and interesting. The same applies to expert work, usually with increased intensity.

How do you prepare for a testifying case?

Every case is a testifying case, until it is not. Preparation begins at appointment with clear instructions and a clear recognition of the role and function of the expert. Delivering that role independently and objectively is key. That approach best serves clients’ interests, as it gives them the best information to make good business decisions, and fulfils the requirements and obligations of an expert’s role in assisting the tribunal. I have seen named experts who do not prepare their reports themselves – or who operate on the basis that, should the matter look like it will proceed to a hearing, and they will have to testify, then they try to get into the detail at that stage. That is too late and a huge disservice to both their client and the tribunal.

With cases becoming more complex and multinational, how do you ensure that projects run efficiently?

International arbitrations, with their scale and complexity, are projects in their own right. Many of the project management techniques applied to construction – planning, scheduling, budgeting, resource management, monitoring, etc – can be brought to bear. As projects become more “data rich”, the management and investigation of that data has become key to successfully and efficiently marshalling the contemporaneous record of fact. Good and trusted expert assistants underpin effective delivery and are an element of successful expert work that deserves more recognition. Couple that with collaborative working tools, data forensics and analysis and you create an environment within which appropriate expertise can be brought to bear efficiently and effectively.

How do cases come to your attention?

Most of my expert appointments originate from referrals from counsel or clients that I have previously worked with. That is always flattering.

There is that perennial problem of how you get your first appointment. The first question to a potential expert is usually “Have you been appointed?” followed by “Have you testified?” If the answer to the first is no, that can be challenging to overcome. I was fortunate that my first appointment arose from an approach to the firm that I worked for, and that my experience at the time satisfied the requirements.

What is the best piece of career advice you have received?

Three things have stayed with me.

“Choose a job you love.” I am not sure that I “chose” it, but I am very fortunate that I do something that is both challenging and satisfying.

“If a job is worth doing…” Essentially, take pride and ownership of what you do – a mantra of my father.

And, “Thought, belief and action drive achievement” – put much more eloquently by Muhammad Ali and Jesse Jackson.

You have enjoyed a very distinguished career so far. What would you like to achieve that you have not yet accomplished?

I would like to be the best that I can at what I do. There are always things to learn and apply that will help me to achieve that.
