Simon is a chartered quantity surveyor and a member of the Academy of Experts, with over 25 years’ professional experience in construction, consulting and providing expert witness evidence in relation to delay, disruption, productivity, and damages. Simon is often appointed as an independent expert in both international and domestic disputes and has presented written and oral evidence in relation to many matters globally.

What do you enjoy most about working as an expert witness in construction matters?

I enjoy each engagement. They each have their own uniqueness, different types of projects, different contracts, different jurisdictions, and different people. I enjoy working with a variety of diverse clients, the forensic analysis undertaken to figure out the cause, effect and impact of issues that occur and expressing that within an expert opinion.

What is the most memorable experience from your extensive involvement in international construction cases?

There are a couple. My first time providing expert evidence was particularly memorable as it was as daunting as you might expect.

Visiting some interesting projects in different parts of the world provides some good and interesting memories. On such projects, providing expert evidence with multiple languages is interesting and challenging, and it is impressive how such hearings are coordinated.

What are the most common and most avoidable delay and disruption issues that your clients face at the moment?

Most disputes can be routed to the risks taken in the contract. Recent delay and disruption events have been in relation to ground conditions on renewables projects, particularly with who is responsible for the ground conditions under the contract. To avoid such issues, I would recommend taking commercial and technical provisions to address such issues.

What are the key skills involved in collaborating effectively with experts from different areas of expertise?

Personality and the ability to work with others from various jurisdictions and expertise. It is important to understand how experts from other areas impact your work and how your work and opinions impact other experts who rely on it. Maintaining independence is also a key factor.

How does Diales differ from its competitors in the market?

Although Diales experts are spread across the globe, they work closely together sharing significant knowledge with each other and upcoming experts, meaning there is a team of highly qualified experts. There is a significant focus on independence and a high bar to reach to be considered a Diales expert witness. Working alongside some of the technical experts at Diales is interesting, particularly in some of the niche areas of their expertise.

What are the advantages of including experts in the initial stages of construction projects?

There are significant advantages to including experts early on in a project. Most experts have experienced the impacts of projects gone wrong and the pitfalls to avoid. Engaging experts and consultants early in the project will usually provide guidance.

How do you see the sector changing in the near future?

I think there will be an increased use of early/ongoing dispute resolution mechanisms, particularly on larger projects involving international parties.

It will also be interesting to see how AI plays a part in the analysis work undertaken by experts, particularly regarding its reliability and acceptance. I am not sure that it will replace the human element required for working as an expert witness.

What do you wish you had known before starting out as a construction expert?

I didn’t know I was going to become an expert witness; it was a natural career progression as my experience grew and the opportunity or requirement to provide expert evidence presented itself.

Announcing our breakfast session at the Berlin Dispute Resolution Days

Diales Technical, in collaboration with artist Gerry Judah, is delighted to announce its instrumental role in the creation of another stunning central display sculpture for the Goodwood Festival of Speed 2023. This collaborative endeavour with artist Gerry Judah showcases the creative synergy between art and engineering.

Bruno Postle, Structural Designer at Diales Technical, played a crucial role in developing the sculpture’s design in close collaboration with artist Gerry Judah. Their shared vision and meticulous attention to detail ensured the creation of a captivating structure that embodies the spirit of Porsche. Hooman Baghi, Technical Expert and Structural Engineer at Diales, worked alongside Postle to ensure the structural integrity, performance, and safety of the sculpture. Through careful calculations and rigorous testing, Baghi ensured that the design met all necessary requirements.


The temporary sculpture stands twenty-five metres tall and is crafted from steel. Its intricate design features a central dodecahedral core with curved hoops and six straight arms, each adorned with a priceless original classic Porsche car. The arrangement creates a striking composition, with the illusion of the cars bursting forth in motion, showcasing a seamless integration of form and function.


The sculpture is a testament to the meticulous planning and execution by Diales Technical. The steel superstructure, weighing just forty tonnes, demonstrates their expertise in material utilisation and optimisation. Anchored by an underground steel grillage weighing eight tonnes and a concrete foundation, the sculpture stands tall, embodying strength and stability.

The sculpture’s intricate details allude to the craftsmanship involved, with a network of tubes spanning a total length of one hundred and sixty metres, varying diameters of 508 millimetres and 762 millimetres, and fins covering an area of one hundred and twenty-three square metres.


Diales Technical takes great pride in its collaboration with Gerry Judah, which has resulted in the creation of this extraordinary sculpture. Their commitment to excellence and the seamless fusion of art and engineering have produced a captivating masterpiece that celebrates the spirit of Porsche and the of Goodwood Festival of Speed.


The unveiling of this extraordinary sculpture took place during the 2023 Goodwood Festival of Speed from the 13th – 16th July 2023. This year’s Festival of Speed was the 30th anniversary event, which coincides with Porsche celebrating its 75th anniversary of the registration of its first sports car – the 356. Six iconic Porsche cars hang from the Gerry Judah-designed sculpture: the 962, 963, 718/2, 911 Carrera, 911 Sport Classic, and the 365 .

Congratulations Diales Technical, on another successful collaboration with artist Gerry Judah, to realise these fantastic structures. 

We are delighted to be participating in the London Legal Walk for another year.

Taking place on 13th June 2023, the London Legal Walk raises funds for the London Legal Support Trust, who work with over 100 organisations across London and the South East to provide free legal advice for those who would otherwise be unable to afford it. Receiving good legal advice at the right time can make a huge difference to people’s lives, reducing their chances of facing debt, poverty, homelessness, exploitation and discrimination.

Over 13.4 million people live in poverty in the UK and advice providers are at breaking point with the growing need from their clients. Many people cannot afford legal help and we believe everybody should be able to receive legal advice, especially when they need it most.

That is why our team is walking 10k for justice.

Our target is £500.
Please donate to the London Legal Walk by following this link:

Thank you in advance for sponsoring our team, and helping us to raise funds for everyone to access legal aid.

Image of Michelle and her quote

Why did you choose to specialise in the resolution of construction disputes?

I am a Civil Engineer by education.  One of my first assignments was working on the Owner’s team for the Petronas Towers in Kuala Lumpur Malaysia, at the time the tallest buildings in the world. I just naturally fell into the role of negotiating disputes on the project and my project manager suggested this might be a career path for me.  I have now been loving working in the dispute resolution area of construction for over 25 years, so I guess it was good advice.

Why did you choose to join the Driver Group?

There are so many reasons as to why I decided to join in 2020, but on the top of my list was the people I would be working with, underpinned by the company values and ethos. The Driver Group genuinely has some of the most talented people I have worked with to date. They are not only technical, project and claims specialists, but they are also experts at collaboration and communicating knowledge. The company’s ethos, “Worldwide Expertise, Delivered Locally”, means that we combine our industry knowledge with a real understanding for the intricacies of our local markets.  This enables us to give our clients the best possible service and outcomes.

Your promotion to Canadian Director, what are you looking forward to?

I am excited to take on the challenges in my new role, but I have big shoes to fill. Kevin O’Neill who was my predecessor, was the second employee of Driver Trett Canada when we entered into the Canadian market in 2014. Following in Kevin’s footsteps, I’m looking forward to leading our diverse and talented Canadian team and continuing to expand our local and global presence.

What do you enjoy the most?

Outside of my daytime responsibilities, I enjoy teaching at the University of Calgary as part of their Project Management Certificate program.  I enjoy learning from and teaching others.

Approaches to resolving constructions claims in Canada have evolved over the past 25 years, and I hope to continue working with the construction industry to resolve construction disputes quickly, fairly, and in the most cost-effective ways possible.

Tell us something we wouldn’t know about you.

Prior to my career as an Engineer, I spent many years studying to be a classical singer.  However, I promise to never respond to my cross-examinations in song.

We are delighted to be partnering with Clyde&Co to deliver this webinar.

Taking place on Wednesday 7th September 2022, at 1pm, this hour long session will discuss the recent judgement of Martlet Homes Ltd v Mulalley & Co Ltd [2022] EWHC 1813 (TCC) – The first substantive decision from the Court relating to cladding and fire safety.

In a decision that will be of significant interest to the industry, the Court held that a contactor, which had installed a combustible insulated EPS render system (StoTherm Classic) under a design and build contract between 2005 and 2008, was liable for the costs of a full-scale replacement of the system, together with costs pertaining to the ‘waking watch’ whilst it was remediated. The Court found that a repair of the system would not have been sufficient.

The judgment offers a first look into how the Courts are viewing these types of issues in combustible cladding cases. Given the serious and potentially costly implications of this judgment for the industry, we will be co-hosting this remote webinar on 7th September 2022 at 13:00 to discuss the judgment and the practical implications for contractors and developers going forward.

Q&A with Graham Topp

Get to know the new Head of Diales in Oceania

Can you tell us a bit about what your role entails?

I’m grateful to be afforded the opportunity to grow the service provision in Oceania. My focus will be expert and dispute avoidance work in Oceania and the greater APAC region. The aim is simple; consistently produce market leading quality. I’d like to challenge the assumption that age and quality always have a proportional relationship. The instructing law firms I work with see the value in engaging an expert that is present and deeply invested in the quality of the product from the outset. My plan is to keep doing the same, with the support of the fantastic team at Diales.

Who has been the greatest influence on your career?

I have been incredibly lucky with mentors – too many to mention all here. Bill Masters was a great help when I was a junior QS. Anne Connolly’s technical excellence and passion for detail provided a foundation to develop into an expert. More recently, Paul Roberts for his operational guidance and business growth advice. I have been conscious and mindful to at least attempt to take the best from those around me (both upstream and downstream). The single greatest influence has been my late father, Alan Topp. A welder turned pipeline estimator, he was as gritty as they come. He sparked my interest in the built environment.

What has been the best moment of your career?

Accepting the new role with Diales! Looking back, I was also proud when I qualified as a quantity surveyor from Northumbria University with First Class Honours. I was fortunate to be placed on a day-release scheme with my first employer; four days at work and one day at university. It was a long five years. Losing my father during the second year of study added fuel to an already burning fire.

What makes you tick?

Time with family and close friends. I’m a dog person; we have a Boxer and a Red Heeler at home. Exercise is also fundamental. Healthy body, healthy mind.

Tell us a little-known fact about you

Many know that I enjoy competitive cycling. A little-known fact is that I was a medallist in the national karate championships as a junior. I still enjoy boxing for fitness once a week.

We are delighted to announce that Quantum Expert Paul Battrick and Diales Director Chris Sunderland have both been re-elected to the Society of Construction Law Council

On application to the Council, Paul wrote:

My role within Council has reflected my working life which deals with international projects. I have been a member of the International sub-committee and am currently the International Liaison Officer towards the International SCL. I am also one of the two members of the International SCL responsible for guiding potential SCLs towards acceptance within the SCL community. Of late, I have assisted SCLs in Vietnam, Korea and Israel in gaining their SCL status. I hope to continue promoting the SCL internationally and to assist in developing new societies around the globe.


Chris Sunderland has focussed on the communications and visibility of the SCL, and on application he stated:

I seek re-election to the SCL Council following three years of service, during which time, I have been involved in various beneficial initiatives including: as part of the IT Subcommittee to develop the new SCL website to improve its user navigation and experience. The new concept newsletter, which includes event hyperlinks to simplify booking, as well as increasing the use of social media channels to keep the membership and perspective members informed of events, maintaining visibility of the membership. I also sit on the London Programme Committee, and hope to continue to promote SCL’s activities, membership benefits, and ethos to the Construction Law Community.

We are delighted that both staff members are using their respective background experience to support the work of the Society of Construction Law, and we look forward to our continued relationship with the Society.

Diales is delighted to be hosting a CPD event, run in conjunction with the RICS, on The 3 R’s (Records, Records, Records)

Held: 4th December 2019, at The Design House, Al Sufouh Gardens, Dubai.

Change in construction projects almost always leads to an increase in costs and/or delays to completion. The effects of these are often the source of considerable dispute between the parties which could involve lengthy and expensive proceedings to achieve a resolution. Maintaining detailed and good quality records will assist in the agreement of issues.

Phil Duggan from Diales’ Dubai office will explain the importance and context of the necessary documentation to be collected.

Learning Outcomes:

  • A wider understanding of the various records that can be readily maintained on a project;
  • Understand the interaction between parties in maintaining good records;
  • The significance of record keeping in dispute avoidance;
  • The pitfalls of not having adequate records when faced with formal dispute proceedings.

Come hear leading stakeholders in the world of arbitration in India provide their insights on “Arbitration in India in a global economy”. The conference will be followed by a live Q&A session and a breakfast.

Conference Description:

Galloping urbanisation and the need for infrastructure and transportation has made the construction market one of the main drivers of Indian GDP growth.
Arbitration comes within a broader frame where attracting and promoting lasting foreign direct investment is key to supplement domestic companies.

Can arbitration help build confidence for foreign companies willing to work in India? Is India’s reputation of being interventionist towards international arbitration grounded?
Can arbitration awards be challenged? Do the changes outlined in the ongoing arbitration reforms go far enough?

Leading stakeholders in the world of arbitration will provide their insights on India’s overall context supported by various examples of field experiences.

Goodwood Porsche 2018 sculpture

For twenty-two years, the artist Gerry Judah, recently aided by the Diales engineering team (Bruno Postle, Hooman Baghi and Stuart Holdsworth), has been commissioned to build a spectacular centrepiece sculpture for the Goodwood Festival of Speed. This year it is celebrating seventy years since the Porsche 356 was first introduced in 1948.

With 2016’s BMW installation commended for ‘structural artistry’ at the Institute of Structural Engineers annual awards, the pressure was on to deliver something even more spectacular for 2018. Mission accomplished!

A spike mace with long spar arms holding six real Porsche cars weighing in at approximately six tonnes and standing 52m high (the same as Nelson’s Column) – all supported on one slender leg (so fine at the bottom that you can put your hands around it), which is stabilised by anchored steel solid bars. The overall weight is 28 tonnes of perfectly laser cut, doubly curved thin steel plates monocoque.

Goodwood festival of speed

The images speak for themselves, but here’s a little more detail on six Porsche models featured this year.

  • The 356 was the first Porsche produced in 1948, a priceless Coupé model has been lifted forty metres into the air and has been left hanging upside-down.
  • The 917 is an endurance racer, as driven by Steve McQueen in the 1971 film ‘Le Mans’.
  • The 959 Paris Dakar rally winner from 1987, a twin-turbo flat-six four-wheel drive.
  • The 918 Spyder is a hybrid road car from 2015, a 608bhp V8 petrol engine with 286bhp from two electric motors.
  • Another hybrid car is the 919 Le Mans Prototype from 2015, this car holds the Nürburgring Nordschleife lap record, previously unbroken since 1984.
  • The 911R is a limited-edition road car introduced in 2016, representing the latest in Porsche design.

Look closely and you can tell these cars are the real-deal from the visible corrosion and repair jobs they have taken over the years.

The Diales engineering team will be back soon with more details of the challenges and technical know-how needed, along with Gerry’s vision, to keep on making a plethora of amazing vehicles fly!

JACOB’S LADDER is a new sculpture designed by Gerry Judah and engineered by Diales for Gibbs Farm Sculpture Park, New Zealand.

This is yet another collaboration between Diales and Gerry Judah after the success of both the BMW and the Bernie Ecclestone centrepieces for the 2016 and 2017 Goodwood Festival of Speed. The BMW sculpture earned Diales a commendation in the Structural Artistry category from the Institute of Structural Engineers at the 2017 IStructE Awards. Other works recently completed or under construction are a sculpture for Porsche cars at Ascot racecourse, a sculpture for a private collector in Mexico, and another spectacular installation currently in progress for the 2018 Goodwood Festival of Speed.

The Diales team of Bruno Postle and Hooman Baghi, led by Stuart Macdougald-Denton and Stuart Holdsworth, are experts in the field of light-weight, slender and high-performance structures – along with the use of computerised design techniques and Building Information Modelling (BIM) for delivering high precision complex geometries.

Gerry Juday and Diales Jacob's Ladder sculpture

Gibbs Farm is a thousand-acre private sculpture park near Auckland on the North Island of New Zealand. The farm features over thirty monumental sculptures from a roll-call of top international contemporary artists including Richard Serra, Anish Kapoor and Andy Goldsworthy – a roll-call now graced with this elegant new piece commissioned from Gerry Judah. Alan Gibbs is a New Zealand businessman, entrepreneur and art collector who has been assembling the Gibbs Farm collection for twenty-six years.

Gerry Judah is a British artist and sculptor who has exhibited in many locations including the Imperial War Museum and St Paul’s Cathedral. Gerry is also responsible for the last twenty-five years of increasingly spectacular centrepiece sculptures for the annual Goodwood Festival of Speed, latterly assisted by Diales.

JACOB’S LADDER is 34 meters (112 feet) high and weighs 46 tonnes. Made from 480 lengths of steel, stacked one on top of each other, each slightly different in length and size, shifted and rotated relative to the layer below, ultimately producing the final gracefully curving shape – this despite the components themselves all being simple straight steel sections. To achieve this effect Diales created custom software that generated the smooth curved shape, and sliced this shape into layers of varying thickness, all in order to assemble both a structural analysis model and precise cutting and assembly instructions.

The sculpture is on top of a hill in an extremely inaccessible location. The structure needed to account for both tropical cyclones and earthquakes, and was designed to British Standard, Eurocode and local Australian/New Zealand Code of Standards. This was a challenging project delivered on-time and on-budget to the highest levels of detail with an immaculate finish. Due to logistical and on-site constraints, the Diales team provided detailed design including splice-connections and welding to coordinate with the local contractor’s safe method of construction.

Diales Technical awarded a commendation

Diales Technical were awarded a commendation for the « BMW sculpture for the 2016 Goodwood Festival of Speed » in the Structural Artistry category at the 2017 Structural Awards on Friday 17th November 2017.

This was in recognition of their engineering support of the sculptor Gerry Judah, the creative genius behind the Goodwood Festival of Speed’s breath-taking, centerpiece sculptural creations. They’ve been working with Gerry on these projects for a number of years and always rise to the challenges that Gerry’s vision delivers.

The Judge’s comments:

« The new sculpture for the Goodwood Festival of Speed comprises three curved triangular sections, each of which supports a car at their tip. The sections are constructed from rolled steel. The geometry has been conceived so that all of the section sides are developable surfaces that can be fabricated from flat sheets which are rolled into curves to achieve the final form. The steel sheets were laser cut and welded together into the triangular section which provides all of the required strength and stiffness for the structure.

The sculpture is a fusion of art and engineering, and shows an understanding of structural design and manufacturing technology, along with the practical knowledge of efficient construction. »

With Mark Wheeler, Head of Diales and Global Chief Operating Officer at Driver Group, adding:

“We always knew that we had a world-class team of experts working in the Diales technical team, and it’s a pleasure to see their hard work and expertise recognised by their professional body. I know the team really enjoy the work that they do on these innovative projects, alongside their day-to-day activities supporting our clients with their technical expertise.”

Diales has turned five!

Five years ago, Driver Group announced a new approach to the delivery of construction Expert Witness support services and Diales was born. A service that would bring together world-class experts in the fields of delay, quantum, and technical and provide support through a dedicated team, when clients needed it most.

Diales launched with twelve highly-regarded and highly-skilled experts, with published authors[i] John Mullen and Peter R Davidson amongst them. The team grew as launches followed in Asia and the Middle East and more experts joined them across Driver’s worldwide network of offices from Australia to Canada.

Today, the number of Diales experts is closer to 40. The technical team, headed by Stuart Macdougald-Denton, has a dedicated team of researchers, engineers, and architects; many of whom regularly share their wisdom and experiences in the pages of the Driver Trett Digest as well as through social media posts and presentations (a couple can even help make cars fly![ii]).

For a five-year-old, Diales has thrived and developed well, adding further new services and skills and supporting a diverse and fascinating range of clients and disputes around the world.

Head of Diales and Global Chief Operating Officer for Driver Group, Mark Wheeler said:

“The last five years have passed very quickly, and I am delighted to see Diales exceed our expectations year on year. The recent addition of the highly successful technical team has underlined our commitment to this service, and we are excited about the future with new services planned for the next two years…”
