Our Clients

Case Studies

Whether you are undertaking a residential or commercial construction project, Ashdan has successfully managed the procurement and delivery of a multitude of projects for clients in all sectors. Take a closer took at some of our case studies.

We employed Ashdan Consulting as Project Manager, QS and Employers' Agent on our first major construction project.

John’s approach was extremely professional, and the level of service was truly above and beyond our expectations.

He looked after us incredibly well from pre-tender stage all the way to completion. I can honestly say, as I contemplate our next project, that Ashdan Consulting will be our first port of call.

The level of knowledge and experience that John and his team bring is invaluable.

Paul Gordon / Owner The Fish Tank

I couldn't be happier with the level of service provided by John and the team at Ashdan Consulting. Their extensive expertise and detailed construction knowledge was invaluable when helping me handle a dispute with my design and build contractor.

We couldn't have gotten through those stressful months without John's help and often moral support. My word of advice and guidance would be for anyone looking to embark on a build, get Ashdan Consulting to review your contract for works BEFORE the build commences, they will save you a fortune in the long run. First class service and can highly recommend. 

Private Client / Northumberland

We engaged Ashdan Consulting to advise us on a contractual issue on one of our projects and found this to be invaluable support. 

Their advice was clear, prompt and professional, and it provided us with an excellent basis on which to progress our claim for entitlement under the contract. 

They would certainly be my first choice to work with again, and I would thoroughly recommend them to anyone needing contractual advice or claims services.

Phil McGuire / Regional Director Vaughan Engineering Services Ltd.

Our first project with Ashdan Consulting at Catherine House was via a personal recommendation, which has proved to be absolutely correct.

Their attention to detail and the service they have provided us on what is a very tricky project has been fantastic, and I will certainly be working with them again on our next development.

Tom Heaney / Property Investor & Developer

We have used the services of Ashdan Consulting several times over the past two years, ranging from a bit of guidance over the phone to more in depth and complex issues we have faced in relation to contractual disputes.

Every time the service and advice we have received has been fantastic. This has resulted in saving us time and money, and more importantly has reduced stress!
I have no hesitation in recommending John and the team for any of the services they offer.

Joe Dixon / Managing Director JD Homes (NE) Ltd

I have known and worked with Ashdan Consulting for several years.

They have a proven track record in the construction industry, providing an excellent Commercial and Project Management service.

I continue to work with Ashdan to the present day and value their contribution to my business immensely.

Eddie Tribe / Managing Director Amsted Developments Ltd.

We approached Ashdan Consulting to support us in the Quantity Surveying role required to complete the Milburngate project in Durham. They were required to liaise between the Client, our Project Manager and the legal teams to develop the contractual requirements for the project going forward, as well as managing the cost negotiations for the ongoing works. The expertise provided by Ashdan enabled us to confidently undertake the works required by the Client to progress their development through a very difficult situation. They kept us fully informed at all times and coordinated all commercial communications with the Client. With Ashdan’s support we were able to fully recover the costs we incurred in completing the works.


At all times Ashdan acted professionally in the way they conducted their business and I would have no hesitation in recommending their services.

Kevin Robson / Commercial Director, Thompsons of Prudhoe Ltd

Your report was excellent, thorough and clear, and it really helped us navigate the quantum matters, so thank you very much.

 Our client was also very impressed with you and your work, which was great to hear

Anne-marie Knight / Partner Weightmans LLP

“I have recently been working with Ashdan Consulting Ltd on a complex construction claim where the company provided Expert Witness & Quantity Surveying Services. I was dealing with John Johnson the Managing Director who from the minute I spoke to him I knew he had a vast range of experience.

 Having worked in the Construction Industry for over 30 years on several large projects John spoke the same language as myself and we both had exactly the same viewpoint on the various elements we were discussing which was very refreshing. I found John very diligent, knowledgeable and lived and breathed the claim that we were dealing with. John was supported by his team who worked diligently in the background to pull all the pieces of the required documentation together which was not an easy process. All of this was carried out under a very tight timeline, they reacted quickly when we asked him to look at alternative connotations.

I would not hesitate in recommending John in this role on similar projects and I hope one day I will work with him again”.
