About Us

Our story

Since our formation in 2011 and under the guidance of founding Directors David Diesbergen and Simon Blair, D2 has strived to add value to our clients by providing construction know how to de-risk delivery of projects. The intention at the outset was to leave a lasting legacy on the UK construction industry through a combination of sound technical delivery together with an unconstrained view of processes and technology.

Over the past decade we have developed a comprehensive suite of programme management capabilities, ranging from traditional project management to planning and controls, through to information management, digital technology and carbon and sustainability. These services are today captured in our Programme Management Service Model and supported by our growing team of project professionals with shared values and commitment to delivery.

We have built a sound reputation for:

  • Delivering our commitments
  • Successful delivery of projects running into the £billions
  • Thinking “outside the box”
  • Developing talented project delivery specialists.

Our reputation serves as evidence of our passion to deliver our mission:

Working together to develop intelligent programme management solutions, helping to deliver a more sustainable world.

We believe our experience and reputation along with the services we have developed position D2 to support successful development and delivery of projects of all shapes and sizes. Our growth in the UK, and more recently in North America means we are now well placed to influence the global infrastructure market.
