Mario Cosic Erdbau-Technik GmbH

We were put in touch with Virtus Massivhaus. Upon inquiry, we learned that they are the go-to civil engineering company for Hamburg and the surrounding area. This was a plus, as we valued a smooth process. The initial contact was excellent, and the collaboration during the quote calculation for the earthworks was superb. We also had them handle the garden preparation, which saved us a significant amount of money on our narrow plot. Later, we also had them do the utility work. It was a shame that we only received their contact information so late (after we had received the building permit).

A truly customer-focused company. Great employees who think proactively, owners who promise and keep appointments, fair pricing, and workmanship that was more than positively received by my house building company. If you need an earthworks contractor, contact Cosic Earthworks Technology!

A big thank you to our civil engineer Mario Cosic for his fantastic support during our house construction! From the initial planning to the final implementation, the collaboration was simply top-notch. I would particularly like to emphasize his punctuality and reliability. The entire process was stress-free and efficient, which was a huge relief for us as the builders. Communication was always friendly and professional. We are extremely satisfied with the result and can recommend him without reservation!

I can wholeheartedly recommend Mario Cosic, the company that helped us with our house construction! From start to finish, the collaboration was absolutely professional and seamless. We were very impressed by his expertise and dedication. The work was completed on time and to our complete satisfaction. I would particularly like to emphasize his flexibility and understanding of the unexpected challenges that inevitably arise during construction. Thanks to his support, our building project was completed on schedule and without any stress. Thank you so much for the excellent work!

Our contact person was Mr. Beck – his quote arrived quickly and was completely transparent. All questions were addressed directly and explained in detail. The price was excellent, with no unpleasant surprises later on. The work was carried out on time and flawlessly, and the site was left clean. We highly recommend this earthworks contractor!
