Excerpt of an e-mail from an engineering firm in Darmstadt

Site inspection of pipe jacking OD 4100 in Mannheim 

On behalf of our colleagues, we want to sincerely thank you once again for this "once in a lifetime" opportunity to experience such a large-scale pipe jacking project live near us. We and our student trainee Leonie acquired some impressive images and insights into the size, incredible technical demands and your perfect site logistics at the jacking construction site. 

When we plan jacking projects in future, we will be looking at these in an entirely different light and we will be planning and tendering in an even more practise-oriented manner with greater confidence! We wish the entire project TEAM and the company Sonntag "Good Luck!" both now and in the future!
