… family-owned for four generations

People, ideas and the cornerstones of our success

DIRINGER&SCHEIDEL

1921DIRINGER & SCHEIDEL Bauunternehmung was founded by Franz Anton Diringer in 1921.

Today the permanently family-run civil and construction engineering group of companies with its head office in Mannheim/Germany (70 km to Frankfurt) has

about 2,100 employees and a turnover of 300 million €.

1946The son-in-law Heinrich Scheidel enters the company in 1946. The extension to other fields of activities follows. Thanks to his entrepreneurial spirit the company develops to one of the most important medium-sized companies in all the sectors of civil and con-struction engineering in the Rhein-Neckar area immediately after the end of the war.

1969On this solid foundation the son Heinz Scheidel, and under his leadership meanwhile the third and fourth generation of the family, is not only able to continue the business operations, but even to successfully respond in time to the rapid structural changes in the building industry.

1973In view of an increasing concentration of companies in the building industry, one of the entrepreneurial answers is “take-over instead of being taken over”. By means of

systematic investments and expansions of the company, the course is set for the group to henceforth establish itself even in special markets. Parallel to the realisation

of numerous building activities for the industry, trade and commerce, the first own project developments are already made at the beginning of the seventies.

1989The circuit of production, improvement and processing of raw materials is closed. From now on the group disposes of an own gravel-winning plant and a plant for the production of lime sand brick, porous concrete and ready-mix concrete. The German reunification affords the opportunity to transfer the entire business activities to East Germany. At the same time, a most dynamic expansion of the own property development division takes place. The main establishment with an own administration and an own storage and maintenance yard is founded in Dessau-Roßlau and a further place of business in Leipzig follows. DIRINGER & SCHEIDEL is one of the major employers in the building and construction industry in the region between Berlin and Leipzig to this day.

2000DIRINGER & SCHEIDEL Wohn- und Gewerbebau GmbH increases its activities in the service-property sector and successfully sustains its position in this future market with new living and servicing concepts. ARIVA Hotel GmbH and avendi Senioren Service GmbH, the subsidiaries developed from this, are presently operating three hotels with modern convenience – two in cooperation with Best Western Germany – and sixteen facilities in the sector of service-living for senior citizens as well as out-patient and stationary care.

TODAYDIRINGER & SCHEIDEL successfully sustains on a growing market. About 40 percent

of the personnel are meanwhile working in the service sector.Further projects of housing, commerce, hotel, nursing care as well as office or

industrial buildings and plants are in planning or realization stage.Although constant investment in the state of the art technology, plant and equipment

keeps us ahead in terms of hardware, our greatest good in the group remains our professionally qualified and competent staff. Their solidarity with the company

ensures that almost a century of experience, knowledge, know-how and motivation has passed on to the next generation. Management and employees at all levels look

forward to the future with confidence.

1993Project and property development become an independent area of responsibility of DIRINGER & SCHEIDEL Wohn- und Gewerbebau GmbH with meanwhile 30 regular members of staff. At first ACCURATA Immobilienverwaltung GmbH and later on DIRINGER & SCHEIDEL Gebäudemanagement GmbH develop from this responsibility. On behalf of their owners both companies provide hand in hand all the administrative and technical services around the property.

1996A further future-oriented option opens up in the building sector. DIRINGER & SCHEIDEL

Rohrsanierung GmbH develops from the successive merging of four companies specialised in the rehabilitation of pipelines and sewers. Due to its large scope of activi-

ties the company disposes of the complete and complex know-how and nearly all the processing techniques for the high-tech rehabilitation of sewers and pressure

pipelines. With its specialists working throughout Germany and the European countries, it has become one of the market leaders of the sector.

Shell construction is the classic activity for a construc-

tion company and formed the foundation of our

family enterprise in 1921.

Thus, we played a major role in rebuilding the

city of Mannheim after its destruction in World War

II and continued to consequently and constantly

widen our scope of activities.

This soon included “turnkey” construction of

individual, residential and commercial buildings as

well as complete housing estates. Later on industrial

plants and power stations followed.

The traditional and the modern

Shell construction forms the nucleus of our company group

Today, we also provide complete maintenance

services and constructional management in both

the residential and the industrial sector.

We intentionally combine traditional solid crafts-

manship with the latest technical know-how, thus

giving us the confidence to continue fulfilling our

customers demands in the future.

We have been cooperating for decades with many

leading architects and we have a planning department

of our own always willing to realise also your own ideas.

Involve us from the very start in planning your

commercial property project. Our well coordinated

team of experts (also certifying buildings according

Architecture and turnkey construction “under one roof”

The proof of good planning lies in the sustainability of the entire construction

DGNB® or LEED®) under one roof ensures maximum

efficiency and minimum interface problems.

Aesthetically ambitious solutions, flexible room

designs, energy and resource saving concepts,

construction costs and subsequent operating effi-

ciency are all factors foremost in our mind. We call

this integrated planning and building.

Our specialists can rely on each other’s compe-

tence. Coordination does not require lengthy run-ups.

Synergies do not have to be sought, since they are

already there. No planning detail is lost. Added values

are the result.

Know-how in each dimension

Men, machines, materials … at high level

As a member of the “Güteschutzgemeinschaft

Kanalbau” (Quality Control Association for Sewer

Construction), the responsibility lies with us to ensure

solid quality of the high-value materials and machines

used and to consistently provide intensive further

training for our employees. Thus our customers have

the guarantee that work is always carried out at the

highest level.

Whether we build roads, bridges, railways, ditches,

drains or sewers – we are “in deed” at home in

each sector!

Utility pipelines are the backbone of a functioning

infrastructure. Without electricity, water, long-distance

heating or gas “nothing works”. Thus the responsibility

for construction projects in this sector is extremely

high, and then utility pipelines even hold special risks.

Legislation is exceptionally strict, in particular

as far as gas and water are concerned – and this is

justified. Only those are allowed to work in this sector

who have the appropriate technical qualifications

and who can guarantee for safety and hygiene both

during and after working.

We have, of course, all the required licenses,

we are for instance a licensed specialist operator

for the “DVGW 1 + PE and the W1 + PE” and, in addition,

we hold the industrial welding fabricator license.

Our customers can be sure that we care for safety.

From compact pipe and the various hose lining

procedures via cement mortar lining, textile hose

relining, swage-lining, pipe relining, robot technology,

underground pipeline rehabilitation up to burst-lining

procedures and manual rehabilitation as well as the

mounting of cap sockets for the connection of

branch lines to buildings: as a market leader, we offer

our clients custom-fit and economic solutions from

one source based on a prior comprehensive system-

comparing analysis.

Environmental influences and the ravages of time

all “gnaw” at every kind of building. The answer is:

sound refurbishment and restoration.

For concrete refurbishment, we offer all-in

services from one source beginning with the damage

analysis via the preparation of the refurbishment

concept to the execution of work. This applies equally

to residential buildings, bridges and industrial or

dock facilities.

Protection against chemical and thermal influ-

ences by means of appropriate coatings in the indus-

trial sector: specific and professional protective

measures pay off in the long term.

Maintain and preserve …

Many know “what” – we know “how”

We carry out reinforcement of the load bearing

capacity of floors, concrete props and bridges, because

we are one of the few companies in Germany who

hold the license for the adhesive reinforcing with

carbon fibre reinforced plastic (“CFK”) and steel plates.

The restoration of natural stone and buildings

of art-historical importance requires qualified spe-

cialists. We have them.
