Price for building with consideration - SONNTAG receives honor
Rhein-Zeitung, December 2011
The trenchless construction of an aircushion culvert under the rivers Enz and Nagold commissioned by the municipal sewage Pforzheim (ESP) was awarded two prestigious national and international prizes. Executing building contractor of this 16 million euro project was the company SONNTAG Baugesellschaft. The branch office in Bingen was responsible for pipe jacking of 1400, 1600 and 2200 diameter tunneling pipes and provided the engineering work, as well, all from a single source.
First of all, the “Enz” culvert earned the "Big Project and BGreen Award" in the category "water conservation“. The prize is is awarded in Dubai every year in honour of special construction projects in the areas of "engineering" and "sustainability".
The second prize was the GSTT Gold Award for outstanding trenchless construction projects. For SONNTAG Baugesellschaft it was already the third GSTT award as a project partner. “Remarkable achievements, with which we have made a beautiful Christmas present to ourselves”, as the SONNTAG corporate group responsives commented on the prize awarded in early December at the sanitary engineering conference "Dortmund Sanierungstagen".
The GSTT Award is presented by the "German society for trenchless construction and maintenance of piping” [Deutsche Gesellschaft für grabenloses Bauen und Instandhalten von Leitungen e. V.], in order to highlight innovative engineering and heighten awareness of the potential cost savings as compared with open-air construction. Not least of all, it’s about environmental issues, because underground pipe-jacking allows for greater conservation of natural resources.

Fish pass is made in Coblenz
Rhein-Zeitung, August 2011
Nature protection
by a Company in Dörth
Until the opening of the modern visitor center there is to do much "underground work". These highly demanding stabilization, foundation and concrete works will be executed by the Hunsrücker special and civil engineering company SONNTAG situated in Dörth, at the A 61. In addition to the fish pass plant above and below the barrage the team builds a construction for an additional water turbine.
"Bertha" had finally made the breakthrough
Pforzheimer Kurier,, August 2011
Project Enzdüker:
A heavy drill head of 36 tons milled himself 485 meters through the rock under the river Enz
"We are thoroughly satisfied with the previous development of the work", explains site supervisor Mrs. Becker. Yesterday she celebrated the breakthrough of the 485 meters tunnel at the starting place theater street together with 25 construction workers and engineers.
Channel construction work: Most extensive building measures in the civil engineering of the last decades proceed according to schedule.
, April 2010
First town-councillor Martin Ringhof is very satisfied with the course of the most extensive building measures of the last decades. Up till now we could accomplish the set goals without problems and also keep the time and particularly the budgeted costs ".
The instructed company has done good work.
A fish pass comes into being at the Moselle barrage
Blick-Aktuell, April 2010
Minister of the environment Margit Conrad, Dagmar Barzen, president from the structure and approval management North, Felix Stenschke, director of the buereau shipping, Lord Mayor Dr. Eberhard Schulte-Wissermann and Professor Dr. Hofmann-Göttig take the first spade for the new fish pass.
The building costs for the complete project at the Moselle barrage in Coblenz amounts to about 5.5 mio euros. A visitor center and plants to the fish-monitoring which shall be completed by the National Garden Show in 2011 are also included.
Bridge-construction “under rolling wheel”
Kölner Stadt-Anzeiger, October 2009
At night-time specialists set up a new railroad crossing bridge. Strong floodlights illuminated the more than 22 meters high drilling machine. That was used in the Urfttal and controlled by a 28 years old female building assistant.
Place for BUGA-promenading
Rhein-Zeitung, February 2009
SONNTAG carries out the renovation of the walls on the “Konrad-Adenauer-Shore”.
…the first step is the renovation of the side walls. The lowering of the previous wall is part of it between “Stresemannstraße” and “Rheinkavalier” by one meter. This makes the stairless way to enter the Rhine shipping fleet easier for persons in wheelchairs or families with baby carriages in the future. The existing wall must, however, be protected from slipping between “Rheinkavalier” and “Deutschem Eck”. A technically demanding job. A bored pile wall with a 1,600 tons heavy ridgepole must be set up under the surface of the water - exactly the right thing for SONNTAG.
Heavyweight provides thrills
Rhein-Main-Presse, November 2008
The channel construction work between "Bensheimer Straße" and Rhine goes in the countdown. Heavy jacking machine of about 40 tons which shall drive the channel in the soil was let down into the building pit yesterday.
The journey of the "drilling monster" was an impressive spectacle: Alone the 200 ton car crane which towed the machine to the oversized excavation was worth looking at.
Canal construction is possible without deep ditches
Rhein-Zeitung, July 2008
Sonntag Construction Company from Dörth is specialized in "Micro-tunnel-technology". Drills with gigantic cutter heads pioneer an underground way for the pipes.
Canal construction without excavators?
Sonntag Construction Company from Dörth practices this already for a long time: by "pipe jacking" it finishes work which otherwise would not be realized at all.
Canal under “Lenneuferstraße”
FAZ, January 2008
What the engineers of the company SONNTAG have done with their machines is unique. The canal had to be driven in a bend under the “Lenneuferstraße” similar to tunnel constructions.
Worldpremiere with technique power
"Allgemeine Zeitung, Worms", October 2007
Steel tunnel with 464 m is laid under the Rhine River …
Laying of the pipes with a new method - worldpremiere celebrates in Worms. Direct Pipe® method is the name of the new jacking pipe method - it combines advantages of established laying system. Diana Pfeff - project leader of the firm HERRENKNECHT and Klaus Borniger - project leader of the firm SONNTAG declare the method.
Canal in “Kirchweg”, Gondershausen
Official Register - Local authorities Emmelshausen, June 2007
Fortunately not only the responsible people are satisfied with the coordinated construction progress also the feedback of the predominate number of adjacent owners are positive. Special thanks go to the employees of SONNTAG. SONNTAG was founded 75 years ago in “Niedergondershausen” and has already more than 40 years ago built the first canal in the street “Kirchweg”.
Hillside situation in CH-Bern with a 28% to 35 % gradient mastered
TIS (trade journal), October 2006
SONNTAG already had experience with the system of hydraulic joints with significantly reduces the force acting on the jacking pipe and also facilitates tight curve radii with an overall pipe length of 3.00 m. The company`s lead in experience was a decisive factor for winning the contract. This high degree of trust on the part of the Swiss building principals was confirmed by the microtunnelling specialists from the “Hunsrück”-area, who provided an entrance to the arriving pit that was exact to the millimetre - at a 35 % gradient!
Laser keeps pipe in line
“Mitteldeutsche Zeitung”, December 2005
“This so-called jacking system for laying the main collection drain” explains AZV Director, Ines Koeckeritz, “Is the more affordable option when compared to open sheeting where the road would have to be torn open.” “We would have had to pump and clean over a million cubic meters of groundwater. This would have caused a 20% increase in costs. Now we only have to lower the groundwater for the pits. In addition, the road remains accessible.”
