“Peter I just wanted to thank you for all of your hard work in preparing for the case against XXX and for giving evidence at the trial. I know it must have been a little stressful but thought you performed really well.”

“Dear Peter, I wanted to thank you again for all your help and all the time you put in preparing for the hearing. I know cross-examination isn’t fun, but on the whole I thought you went well and you stood your ground.-- I have enjoyed working with you and learning just enough about LPG plants to be dangerous.”

“Dear all, Congratulations on a successful week and many thanks to each and every one for the valuable contribution.”

Thank you so much to you and all your team for all your hard work on your report. We think it is a very good piece of work.

It has been great working with you and likewise hope we will have the chance to do so again in the future!

A belated thank you for all your work over the past 18 months or so. It has been a pleasure to work with you on what has been a demanding case from a technical and forensic perspective and the clients were helped tremendously by your ability to ferret out inconsistencies in the documentation / photos. I hope you enjoyed the experience of giving evidence notwithstanding the attempted attacks on your credibility and independence. We and counsel felt that you did a very good job in the witness box and managed to deal effectively with all the attacks.

The work done was to a high standard and the output met our requirements as well as the needs of our legal team.

Thanks so much to both of you for all your efforts and hard work for us.

Thanks for all your hard work on the case over the last year. I was very impressed by your performance under cross examination and in the hot tubbing session. You got the tone absolutely spot-on in terms of explaining your position with authority whilst recognising your obligations to be a neutral expert. The client was also very impressed – which, after all, is the main thing!

“Peter, good presentation, well done and thanks.”

A quick note of thanks for your guidance, expertise and patience with us throughout this process. You are a consummate professional and we sincerely appreciate all that you contributed to this effort.

“Dear Mr Lumley, Many thanks for your report, which I have read through. It is immensely helpful and clearly set out. I appreciate that you do not have some of the key documents that you would normally expect to see but have still produced a very cogent narrative that accommodates the gaps in information.”

“Dear Peter, We succeeded on the XX claim and partly on the delay claim. Please find attached the judgement. Thank you again for all of your help, which was much appreciated.”

“Dear Peter, Thank you for your assistance yesterday at the Hearing, it was very much appreciated……your evidence was invaluable and I thank you for your assistance in this matter”.

“Dear Peter, Please see attached [...] decision in the [...] adjudication. He has unequivocally decided in Bilfinger’s favour and this is in no small part to the clarity of your report.

"Thank you very much for your help with the wider case-it has been a pleasure working with you!”

Telephone call to thank Mr Lumley and the Manderstam team for the excellent and professional performance in the preparation of the expert reports and in particular our performance (Mr Lumley and Mr Sellers) at the hearing. He said they could not ask for more and it was a credit to ourselves and Galliford Try. He complimented us on our hard work, enthusiasm and grip of detail.

“Peter, Graham, Thank you very much for all your hard work on the case which is contributed in no small part to the result. Best wishes and I hope we can work together again in the future.”

“XX do not wish to contest your evidence and so you are not required to attend the arbitration. I cannot thank you both enough for everything you have done on this case”
