..."During my site visit today together with the HSE staff, I gained a positive impression of your construction site. The work areas were clean and tidy, personal protective equipment was properly worn by all employees, and the barriers in sensitive areas were correctly implemented.

It is nice to see that the topic of occupational safety is taken seriously. A tidy and safe working environment significantly contributes to avoiding accidents and ensuring smooth construction operations.

Thank you for your commitment - please feel free to pass this feedback on to your team."

... the old year has come to an end with a great effort for the wastewater freedom of Emscher. Despite all the adversities during the challenging Corona times, all parties involved, including construction companies, planners, project management, and even approval authorities, have achieved this important milestone in a very good collaboration. In particular, due to your great expertise and incredibly high work commitment, you have turned the planning into reality at many construction sites, all in a very pleasant cooperation.

I would like to sincerely thank you for your company's great commitment to our measures. The many diligent hands that have contributed on-site in all weather conditions with plenty of overtime deserve my special recognition...

... Noise and dust from a construction project are much easier to endure when caused by such a friendly team - like here. Huge praise for these people. Always friendly, helpful, and in a good mood. And, this will surely please you, extremely hardworking.

... I would like to thank your wonderful employees who have been working with us on the Niers for months! It is incredible how kind and considerate the men are. No matter what time of day, whether early around 6:30 or in the evening around 7 PM and later. They always drive considerately, wait until all the dogs are gathered, greet you, and when you walk through the construction site or meet one of your employees, they always have a kind word!

Please convey our heartfelt thanks to your employees!!! And also a compliment to the company SONNTAG for having such valuable people they are allowed to work with.

Ruling from our client regarding a sewer construction project in Bonn:

"Once upon a time, there was an old sewer.

Located in Bonn on Roland Street, its condition was already quite bad.

The Stelter office thought about the old sewer, the sick one.

It can't stay like this, the best would be to drive a pipe forward.

Soon the idea is captured on paper, the city brings in the company SONNTAG.

With a slightly modified proposal, one goes to the matter, one realizes the company is specialized.

The team around Master Distelrath is not afraid of any work.

For the residents on site, one always finds a friendly word.

Now the sewer is newly laid and tight, so it is finally completely righted.

Many thanks to the whole group, you are a great team."

Site visit pipe jacking DA 4100 in Mannheim

On behalf of my colleagues, we would like to sincerely thank you once again for this "unique" opportunity to experience such a large pipe jacking project live so close to us. We, and especially our working student Leonie, were able to take impressive pictures and impressions of the size, the immense technical requirements, and their perfect site logistics at the jacking site.

Future jacking projects planned by us will now be seen "with different eyes" and we will be able to plan and tender them in a more practical and safer manner! Best wishes to the entire project TEAM and the company Sonntag "Glück Auf"!

... today we would like to pass on a heartfelt thank you that was reported to us from the operational business. The extraordinary commitment of your company and the support specifically from Mr. Bauer in addressing the water pipe break on January 29, 2019, on the factory premises has been expressly praised by the energy service at Merck: "... have helped us excellently in resolving the unplanned disruption. We are glad to be able to rely on such reliable partners even in unplanned exceptional situations. We as energy service would like to take this opportunity to thank you for your readiness to respond and the good cooperation. Without the ... mentioned companies, the operational disruption for the affected production areas would not have been able to be resolved so quickly."

We at Strategic Contracting are happy to join this great feedback and are pleased that we have such good framework contract partners in use at Merck. The special performance in this disruption case will be taken into account in the ISA company evaluation system and will be reflected in a special evaluation by the responsible employee in the energy department.

... I would like to thank the colleagues at SONNTAG. The team led by Mr. Depil executed the project on Braunschweiger Straße. The collaboration with Mr. Depil from SONNTAG worked excellently again.

Short-term changes to the traffic management were possible without any problems. Particularly commendable is the fact that the colleagues at SONNTAG managed to complete the work ahead of schedule to alleviate the tense traffic situation at this location.

The civil engineering group would like to take the opportunity at the end of the year to express great praise and thanks to you. My team and I would like to express that we are very satisfied with the performance delivered in 2019. The willingness to perform and the quality of work have maintained a very high level over the years...

Even if the compliment to the teams working in the trench in all weather conditions is too short or does not reach them, we appreciate the difficult conditions under which the performances are sometimes delivered. Therefore, here at this point, a specific praise for the staff.

Excerpt from an email from a client from Darmstadt

12/2019

Mr. Abate and I feel it is necessary at the upcoming end of the year to inform you that your teams, primarily your foremen Mr. Viktor Bauer, Mr. Kevin Strunk, Mr. Dennis Schulte, and Mr. Laurenz Imhoff, as well as your construction management represented by Mr. Lauderbach, have consistently delivered excellent and qualified performance. We would like to particularly highlight your personal skills, such as communication in all directions ...

Only through this way of lived work philosophy has it been and is it possible to handle the always time-critical measures under not always quite simple conditions at a high level of production...

Excerpt from an email from a resident of Walporzheim

08/2021

... a thousand THANKS for your great flood relief in Walporzheim: utility water tanks and material boxes with rubber boots, buckets, and shovels, exactly what helps us affected people a lot! Your voluntary commitment, just like that of the many helpers from agriculture and landscape gardening, is beyond words. An overwhelming sign of lived solidarity! Full of thanks with warm regards from Walporzheim.

Excerpt from an email from a resident in Essen

Dear Sunday team,

for 3 years we have been living almost door to door with Guido and his team here in Wolfsbachtal in Essen. A big task needs to be completed and Guido's team is doing great. As dog owners, we constantly encounter each other on our daily paths and we take care of each other in a way that is really wonderful. We wanted to share this as it is not something to be taken for granted. Please let us know, as we will be moving away from here in November 2021, when the construction site will be finished. We would love to prepare a nice farewell for the team with a farewell drink/meal.

Excerpt from an email from a client in Koblenz

11/2021

... as you surely know, our new high-pressure pipeline in Bad Neuenahr was completed last week. The Rhein-Zeitung aptly referred to the pipeline as the "main artery" for the heat supply in the flood region." This definitely ensures heat supply for thousands of residents in Bad Neuenahr-Ahrweiler before winter...

Without your prompt confirmation to carry out the necessary microtunneling earlier than planned, we would not have managed this. We are very much aware that this has affected your other construction sites.

With all this in mind, we would like to sincerely thank you today for your support. Please also extend our thanks to your employees. We look forward to continued good cooperation with your company.

07/2016

... we are directly affected by the canal construction measure at Villiper Hauptstraße 28 and would like to briefly share our experiences with your team: Simply great how your people behave!

This makes all unavoidable disruptions bearable. Congratulations on such a team! Wishing you and your people a nice weekend.

Excerpt from an email from a resident in Wiesbaden-Bierstadt, Sandbachstr.

05/2017

Your on-site team led by Mr. Fuhrmann has managed to minimize the disruptions for all parties involved and respond kindly to residents' "special requests"! To handle such a comprehensive project in what I would almost call record time commands great respect from all of us here in Uhlandstraße!

The city of Wiesbaden would be well advised to hire your company for further construction projects of this kind! Thank you once again.

I have never encountered such hardworking, tidy, friendly, polite, and helpful workers (with humor) from a construction company...

Excerpt from an email from a resident in Wiesbaden, Uhlandstraße

10/2014

... it concerns your construction site in Wiesbaden, Uhlandstraße. It must also be praised: We have noticed that your employees working on the construction site are very coordinated, handle the site remarkably orderly, and thus work effectively.

The employees themselves are extremely polite, courteous, and helpful in keeping the "disturbance" to the residents as low as possible. A friend of ours, a construction engineer, civil engineering, 35 years in construction, was also very impressed by the construction site and the way of working.

Congratulations on these people and the obviously good working atmosphere!

Excerpt from an email from a resident in Wiesbaden, Uhlandstraße

10/2014

AND I WOULD LIKE TO THANK ALL THOSE INVOLVED IN PLANNING AND EXECUTION WITH GREAT PRAISE!

Excerpt from an email from a client

12/2009

For my part, I can only emphasize once again that the construction project was one of the most interesting and best-organized projects for me personally and, I think, for all involved.

The collaboration with the team of the company Sonntag, including the subcontractors, engineering firms, utility companies, and us as a city was simply outstanding.

Excerpt from an email from a resident in Wiehl

03/2010

The actual reason for this email is a big compliment for all your employees who were working on Bürvigstraße. We residents were always treated very accommodatingly and kindly. Necessary communications (e.g. moving the car out of the garage, etc.) always came in time; inconveniences were limited to the unavoidable.

Even though we are glad that the dishes in the cupboard no longer vibrate when compacting, we will keep your employees, dear Mr. Sonntag, and the company Sonntag in the best memory.

Excerpt from the email of a subcontractor for metal constructions

04/2010

However, I would like to mention that we have never had the opportunity to work with and for such a company in our now 14 years of activity, as I was not familiar with such organized and calm work on site; rather, I was used to time pressure and extremely short-term executions.

Excerpt from a letter from a resident in Viernheim

06/2010

For weeks, huge excavators and similar vehicles have been on the move, accompanied by enormous noise.

In this whole action, however, one must praise your team, which is doing its work on site! We have rarely encountered such friendly, helpful, and competent workers. In particular, I must highlight your foreman, Mr. Urban. He is always diligent in ensuring that during the work on the street, residents can always return to their properties with their cars.

Despite the circumstances, noise, and dirt, your employees have managed to make this action very bearable.

08/2011

Finally, I would like to thank the construction company SONNTAG and, of course, especially the project manager, in a special way for his pronounced and strong commitment throughout the entire construction period in realizing a very good and successful site management.

Despite extremely demanding and individual circumstances, which were solely due to the construction site and the ongoing port operations, the collaboration with the local team of the company Sonntag, both professionally and interpersonally, was, in my assessment, an idealized textbook example of the desirable kind.

For this, we would like to thank you!

11/2011

We would like to thank you on behalf of some residents of Backesweg in Unkel for your extremely nice, friendly, and helpful employees, under the leadership of your foreman Jürgen Kiefer.

Due to the enormous scale of the construction site and the construction project, your employees helped older residents to safely navigate the partially construction-related obstacles.

Your employees also assisted with larger purchases, bringing them to the houses, as the residents could not always reach their homes with their cars.

During very deep excavation work extending into the front gardens, the feared damage to the gardens was limited thanks to the skill of your excavator operators. The traffic management was prudent. In cases of necessary closures of parking spaces, flexibility was shown as much as possible to accommodate the needs of the residents. Dirt from the excavation work was quickly removed. Questions from the residents regarding the technique, execution, and further progress of the work were answered briefly but competently and always politely.

Of course, we are now glad that there is more peace in our street again. However, for those like me who have experienced the readiness for action, professional skills, and friendly demeanor of your
