Dear ABP,
Collectively you undertook [survey] work on 100 assets with varying degrees of complexity which tested your versatility and resolve to the limits.
For the second year in succession, please accept my personal thanks to you and your teams for a 100% delivery of the project, on time and on budget.
Particular recognition is justified to our hard-working administration teams, without whom we would doubtless have failed.
I look forward to working with you again.
Regards,
Ray, Lead Projects Manager
