Groups own construction and maintenance operations.For the companys Department of Engineering and Bridge Construction we also manufac-ture such useful constructions as moving equipment, mobile cornace slab carriages, tempo-rary bridges and pipe bridge portal cranes. But also for the area of above ground level construction, composite beams, girders and trusses, special assembly help constructions, pre-fabricated units and steel forms and frameworks are con-structed and built. By 1991, the companys fitter shop had developed into an engineering and facility con-struction department because of their expertise, vast produc-tion spectrum and long year experience with engineering, bridge building and above ground level construction as well as precision steel and factory construction. In a 29,000 m production area, challenging steel constructions are made for the market place. The spectrum of our work ranges from a small project-ing roof to a large, towering docking hall for air ships, from narrow pedestrian walkways to the biggest rail or superhigh-way bridges. Advanced logistic systems, computer aided production processes and a team orien-tated interaction with other
Creative design and engineer-ing of steel buildings and structures as well as the super-vision of all in company elec-tro-mechanical machines and technical facilities have always been executed by Max Bgl
speciality departments in the Max Bgl Group allow the production of even the most difficult to move and extra long components and assem-blies. The lengths can range to 46 m and the individual unit weights can be up to 160t. With the help of company owned flat bed trucks and other transportation vehicles, we are flexible regarding the needs and operations required by the job site. With our own railway siding and reloading site, efficient use of the rail way system as well as the near by Main-Donau-Canal is impor-tant for environmental friendly execution. Motivated and qualified work-ers with lots of experience in steel engineering and construc-tion guarantee our customers the highest level of quality and adherence of delivery dates.The ever increasing complexity of the projects is attended to by us with innovative develop-ments as well as modern pro-duction facilities and processes. Utilising our in company and ever expanding know-how, we are securing the productivity and competitiveness for our company groups today and in the future. Given these conditions, steel engineering and construction will also play an important part in Max Bgls new business venture wind energy systems.

SteelPromising materialSteel is not only a material of a great industrial past, it is also very promising in the future. In Germany as well as in other countries, architects and engi-neers have returned to design and build filigree structures which are more spectacular and more innovative than before. They make steel struc-tures an important element of their re presentative and often visionary project designs.
Owing to its properties, as high strength at low weight, excellent plasticity and weld-ability, aesthetic appearance, good re cyclability and long service life, steel is a material unmatched in meeting eco-nomic and ecological require-ments. In combination with wood, glass, concrete, mem-brane and castings, filigree structures as well as optical and functional constructions can be realized.
State-of-the-art computer-aided design in connection with long-standing experience in steel con -struction enables the Max Bgl Group to compute and to deal with spatial structures of ever growing complex ity, and to build such structures to the content-ment of the builder contractor in high qual ity, at reasonable costs and according to schedule. This ap plies to all fields of engi-neering, bridge building and building construction.

Consultation and planning
As a service for the building contractor, Max Bgl steel and plant engineering, with their own engineering and manufac-turing capacities, take charge of buildings and structures of any size up to the whole turn-key project at the Neumarkt build-ing site. Through synergies with the construction pre-cast concrete parts, another core competency of our group of companies, most modern steel-concrete solutions have been
developed which unite the advantages from past com-pound and prefabricated con-structions, for example com-pound prefabricated beams in bridge construction.
To this end the in-house techni-cal office is in a position to do the entire engineering planning service including shop planning, assembly and complete static analysis. The Max Bgl Group is thus able to offer competent
qualified and comprehensive consultation with correspond-ing special proposals at any time, from planning to produc-tion, transport and assembly on site. Owing to the close con-tacts established between the planning department and those performing the building work on site, economical and techni-cally advanced solutions can be proposed to the building con-tractor and put into practice on schedule.

Transport and assembly
A company owned modern effi-cient fleet of vehicle enables the Max Bgl Group to transport steel structures up to 160 t and up to single lengths of 46 m to the place of destination on schedule over large distances. Due to increasing demands on the logistics and environmental protection, steel components
and structures are increasingly carried also by water and rail-way.
Owing to smooth production sequences and perfect plan-ning and prefabrication, even largest industrial halls can be completed in a few weeks time. A large portion of the assembly
work is being done by in-house specialists. In bridge building, assembly work and launching operations of all sizes and dif-ficulties are carried out in close cooperation with our mechani-cal department (MTA).

The companys own steel con-struction manufacturing shop at the Neumarkt headquarters is equipped with high-quality plants for sawing and drilling, cutting and welding, a through -put blast cleaning and coating machine, welding robot, two mill-drill centres with a pro-cessing area of up to 30 x 7 m, as well as a blast cleaning and coating hall for well-proven
Productioncoating methods for corrosion proofing and fire protection. From cutting to assembling and preservation, owing to perfect operations scheduling in connection with optimized planning and production pro-cesses, the Max Bgl Group is in a position to produce more than 3.000 t of steel prod-ucts per month, including the most complex steel structures
and components. The Max Bgl Group uses the latest information technologies in a consistent way, eg, to pass on construction plans directly to the manu facturing shop via CAD interface, thus meeting highest quality demands and ensuring shortest manufactur-ing times. Coordinated quality control in all production steps ensures high production quality.
10
At Max Bgls, self-supervision and quality assurance always rank first. In addition to the QM certificate according to DIN EN ISO 9001, the steel building and plant building sector requires also the large weldability proof to EN 1090 (DIN of 18800 T7), extended to components sub-ject to dynamic stress according to DS 804. Specialized weld-ing engineers with European and internatio nal licences are employed to meet these high quality requirements.
In-house qualified and certi-fied personnel examine the welds by means of various testing methods, including ultrasonic testing. An unbro-ken chain of documents is evidence for the high quality level customary at Max Bgls.
Non-destructive tests: Ultrasonic testing (UT) accord-
ing to the AD code of practice HP 5/3.
Project management Quality management
For us quality means coping with the building contractors demands for quality and dura-bility of our buildings and, at the same time, adherence to schedules and maximum flexi-bility in the realization of tasks.
This means that we strive to achieve high quality in all sta ges of our work to the clear benefit of our customers.
Max Bgls quality management is focused on: A quality management system Safety, health and environ-
mental protection Data protection
The Max Bgl steel engineering and construction division, by bringing these aspects together, guarantees to live up to the high quality expectations of the builder-owner, to deal with the available resources in a re sponsible manner and to safeguard the enterprise.
All employees concerned are timely involved in a project from the calculation to the completion by appropriate organization. The manager is responsible for the necessary activities and coordinates the project also in all divisions at all stages of development.
The general management moni-tors the objectives consistently with the aid of the latest data processing equipment and con-trol tools and renders support for achieving the goals set.

Building construction
Industrial construction and plant building
The boiler supporting structure units weighing tons were transported to the location by means of special heavy load combination chassis.
Power Plant Neurath
Two new power station blocks with each 1,100 MW gross out-put were commissioned in 2012 at one of the most modern and efficient lignite-fired power plant of the world, located in Grev en broich-Neurath. The construction of the 166 m high boiler frame was challenging in its manufacture, transport and assembly of highly pre cise structural steel members with-in the tenth of a millimetre range. This consists of rectan-gular arranged boiler supports, reinforced through a lattice-
work of diagonal bars. The boiler furnace roof consist ing of five main supports, each 220 t on which the 30,000 t boiler is hanging is borne on the boiler support structure at a narrow 170 m height. The structural steel members with in dividual weights between 22 and 145 t were transported by means of special heavy load com bination chassis. The ton-nage of the fur-nace steelwork alone stood at 10,500 t. The total construction steel ton-nage was about 80,000 t.
One of the largest mobile cranes of Europe was used for the assembly of the single steel structure supports and -bars, with up to 145 t individually.
13
The production and mainte-nance hall for the CargoLifters, the biggest airship ever for heavy transports up to a net load of 160 t, was finished at the end of the year 2000. It is situated in the centre of an area of 500 ha southeast of Berlin. Technical highlights of the worlds largest cantilevered hall are the steel trussed arches with a span of 225 m and the shell structure of the two steel gates, which consist of eight segments each. Approximately 14,000 t of steel were wel ded
to form sections, arches, trusses and gates and mounted to the two pivots of the gates. The high demands on the quality of materials, welding techno-logy and tolerances made this difficult building task one of the reference projects of the steel construction and plant building division of the Max Bgl Group.
Today the hall is used as the Tropical Islands amusement park.
The middle, cylindrical part of the enormous hall consists of five trussed steel arches, spanned freely across 225 m.
At a height of more than 100 m, each of the two pivots keeps in place six moveable gate segments of a weight of up to 600 t each.

The museum of traffic and technology (MVT) in Berlin
The German technical museum of aviation and navigation with its visible supporting frame-work is the prominent culmina-tion of the Technisches Kultur-forum near Potsdamer Platz. The extension with its five exhibition levels was built as a steel compound structure with trapezoid trelliswork ceiling. The sophisticated plug-type assembly without screwed con-nections was highly demanding for the accuracy of the steel construction. A supply plane (during the Berlin airlift) freely suspended over spatially sup-ported steel trelliswork and a spider tube structure on the top of the museum of technol-ogy were particularly demand-ing tasks of structural steel.

Hall 7A is regarded a new highlight of the
Nuremberg exhibition site infrastructure.
Hall 7A, Nuremberg exhibition site
The Nuernberg Messe exhibition site has made the Franconian metropolis one of the most im portant trade fair cities in all Germany. Beside the Service Partner-Center, Hall 12 and the Frankenhalle, the new building of hall 7A, too, was adapted to multifunctional exhibition uses. The 120 t triangular pipe trus-ses structure made of bonded laminated wood panel and steel sections are an optical highlight. The cantilevered roofstructure has a span of 85 m and is un -matched in Europe up to now.

Am Borsigturm retailers centre, Berlin
The EHZ retailers center on lake Tegeler See in the northwest of Berlin is a multi-functional shopping and event world with elements of modern times and Germanys period of industrial expansion after 1871. While multi-storey car park and office building were erected as new buildings, the steel structures of the old Borsig workshops, which are protected as a historic mo nu- ment, were integrated into the EHZ complex. For this purpose approximately 130 truss sup-ports had to be completely dis-mantled, derusted, reinforced, coated and reinstalled. A large part of the roof trusses was manufactured anew. Until the complete assembly of the roof, which was constructed in the form of waves of arches, the historical southern brick gable had to be provisionally support-ed in the course of the prelimi-nary building constructions and the steel construction works.

Hall 3A, Nuremberg exhibition site
The new building of hall 3A was the first time a building had been constructed on the Nuremberg Messe exhibition site based on plans by the award-winning architect firm Zaha Hadid Architects. The extravagant exhibition hall is characterised by its steel space framework trussed raf-ter roof structure made from
filigree triangular trusses and by its enormous interior with wavelike steel trusses. Floor to ceiling glass faades end in a slatted treetop-like fan structure that merges into a pointed arch. The striking steel tree trunks were produced in a complex process in the corporate groups own steel construction plant.
Slatted elements in shapes that merge into a point characterise the southern faade of the 3A exhibition hall in Nuremberg.

Sports facilities buildingRheinEnergieStadion, Cologne The modern football arena with its prominent 70 m steel corner pylons will be a new landmark in Cologne, beside the cathedral and the arch, which spans the arena. The individual filigree roofs are sus-pended along their centre lines to provide views unobstructed by pillars or supports for the spectators in the grand stand areas. Like a classical suspension bridge, these roofs are hovering on gigantic trelliswork compres-sion bars over the grandstand section. Construction work was a great challenge for the steel construction and plant build-ing division of the Max Bgl Group not only because of the dimensions and weights of the individual structural steel ele-ments, but also because of the difficulties of their transporta-tion from the workshop in Neu -markt to the Cologne.
Allianz Arena, MunichRheinEnergieStadion, Cologne
Allianz Arena, MunichBuilt as the new home for both FC Bayern Munich and TSV 1860 Munich, the futuristic football arena has a filigreed roof supporting structure that cantilevers freely 65m above the seats and provides protec-tion for 66,000 spectators. The roof construction consists of 9,000 t of steel, roughly 60 % making up the primary construc-tion and 40 %, the secondary construction. The primary con-struction consists of around 65m long and 10m high lattice trusses of box section design and the shoulder area also built as a lattice construc-tion. For reasons of economy, the compression columns were produced in a composite
design in cooperation with our prefabricated factory. The fili-greed secondary construction surrounds the stadium core with a network of Bavarian diamonds that serves as the supporting structure for the 2,784 plastic diaphragm cush-ions. The roof construction is designed as a disc on which the primary construction has a floating support by means of 2,112 sway braces and is stabi-lised in its position by 288 cup spring elements. The vertically arranged faade is attached to the stadium core by five con-tinuous supporting rings.

Commerzbank-Arena, Frankfurt
BayArena, LeverkusenWith the increase of the grand-stands from 22,500 to 30,000 spectators as well as other re -structuring measures in the press, team and hospitality sections the BayArena in Leverkusen has changed into a modern football stadium. Structural highlight of the new arena is the circu-lar stadium roof, with 215 m diameters which will exceed far above the grandstand area. The supporting structure of the roof is based, similarly as the Commerzbank-Arena in Frank-furt, on the principle of the wheel with spokes. Altogether the steel and plant engineering supplied over 2,800 t structural steelwork and nearly 13 km steel cables with a thickness up to 90 mm.

Commerzbank-Arena, FrankfurtMax Bgl Group was responsi-ble for the entire completion of the stadium while it was being converted into a pure football stadium for 47,000 spectators. The steel and plant construction within the corporate group took care of the production and assembly of the steel and cable structure for the retractable roof. The filigree roof structure in spoked wheel principle was made from 2,400 t of steel, 1,400 t of this for the compres-sion ring, the spoked wheels rim. Added to this were cables with a total length of just under 16 km and a diameter of up to 12.5 cm. Furthermore, roughly 2,000 cast parts with individual weights up of up to 7 t were installed.
National Stadium, BucharestThe total package of architec-ture, functionality and economic viability for the new building of the Lia-Manoliu stadium comes from Max Bgl. Romanias larg-est football stadium for 55,000 spectators was built in a mixed construction of site-mixed con-crete and pre-cast parts. The showpiece and visual highlight is the retractable roof with its filigree steel cable membrane structure. The big lift, where the network of 19 km of radial and ring cables with diameters between 20 and 135 mm was anchored, lifted and stretched, was done using strand-jacks and tensile presses at 80 anchoring points on the compression ring.

Traffic buildings
Multi-storey car park The Munich Neue Messe
In a building time of merely twelve months the Parkhaus West multi-storey car park, the currently most voluminous building of the Neue Messe Munich exhibition site, was completed. The seven-storey filigree steel compound build-ing measures 165 x 125 m without extensions and offers place for up to 4,650 cars. Optimized assembly capa cities and a coordinated sequence of the assembly operations for the more than 8,000 individual components ensured economic use of steel as a buil d ing mate-rial and made it possible to erect the shell construction swiftly within 30 weeks.
Roofing of the Nuremberg airport square
Nuremberg airport is the first airport in Germany with direct subway connection. The Nurem-berg airport underground station opened in 1999. The 203 m long station was built in open-cast building method. Its above- ground parts, too, caused sensation: A 5,350 m large, long glass roof made of VSG glazing is supported in spots and partly trussed with sag rods and covers large parts of the external area. The fili-gree architecture is made of more than 120 t of steel. It has a span of up to 13.5 m.
Terminal 1, Hamburg airport
A milestone of the HAM 21 expansion project was the opening of Terminal 1 in May 2005 and of the Shopping Plaza in October 2008. The slightly curved roof, resembling an aeroplanes wing, actually, is a characteristic feature of these two high-tech buildings design. The entire steel structure of the two roof trusses was built at Neumarkt and then transported to Hamburg, where the up to 30 m long, bent steel girders were assembled by means of hydraulic winches to form enormous three-chord trusses of 53 t in total and a span of 102 m each.

The new Stuttgart airport terminal 3
The new terminal 3 is currently being built at Stuttgart airport to cope with the heavy increase in the number of passengers. Its cluster-like spread out tree structure distributes the load of the hall roof via branches and boughs to the 18 trunks made of cylindrical rolled tubes. The steel structure elements prefabricated in Neumarkt (in all, 1,170 cast-iron knots, 65 per
tree, had to be welded) were assembled step by step in pre-assembly scaffolds outside the building area proper. The quar-ter trees were then lifted in place and welded to complete trees. An advanced assembly concept ensured smooth and swift erection of the uncovered supporting steel structure with the roof grillage of a total weight of 1,700 t.
Nature acted as the model for the supporting structure at Stuttgart airport.

Bridge buildingISB Intelligent Segmental Bridge Bgl
Max Bgl Group offers you an innovative kind of bridge with the prototype of a bridge struc-ture with separate load-bearing system: the ISB Intelligent Segmental Bridge Bgl. The prefabricated bridge impresses due to its segmental structure made from composite prefabri-cated supports and pre-stressed pre-cast concrete slabs made from high performance con-crete which can be driven on straight away without any seal-ing and surfacing. The advan-tages of this new building prin-ciple for bridges are obvious: very short construction time, economical manufacturing, low maintenance costs and easy to inspect.
The top structure for the ISB Intelligent Segmental Bridge Bgl is divided into two sepa-rate load-bearing systems. The main load-bearing system is made by composite prefabricat-ed supports produced in series at our own steel construction plant consisting of airtight welded steel box girders with integrated concrete top boom. On top of these composite pre-fabricated supports lie high per-formance concrete pre-cast slabs that can be moved length-ways and do not have a rigid shear connector, and which are stretched and held together in the longitudinal direction of the bridge using an external strand post-tensioning system. The lanes for pavements and cycles are already integrated into the concrete pre-cast slabs produced in high precision work at the plant.
Compound bridges
The majority of the road bridges manufactured in the Neumarkt plant are compound bridges of various cross-sec-tions. In contrast to railroad bridges, the compound design as opposed to pure steel brid-ges with orthotropic car riage-way plate has become widely accepted for road bridges. Ex -amples of compound bridges are the Tangermuende Elbe bridge, which is an arch bridge, and building 2 of the Wuster-mark by-pass road, which is a trough bridge.
Railway bridges
Railway bridges are built as lattice girder bridge, trough bridge or deck bridge. These are for the most part pure steel structures. The railroad bridges ma nufactured at Max Bgl up to now are exclusively lattice girder bridges with gravel trough. The longest of these bridges is the 292 m Rhine bridge at Maxau near Karlsruhe.

Architectural highlight of the platform road train is the 128 m high steel pylon of the Ziegelgraben bridge. With its harp structured cable
suspensions, it bridges the Ziegelgraben and the waterfront of Stralsund.
Steel structure challenge: Within the area of the crossing of the B 96, slanting struts are connected in the upper structure and will be combined through a cut water in the gusset.2
nd Strelasund Crossing, Stralsund
Germanys first bridge build-ing that was tendered and planned according to new EU regulations consists of six individual bridge buildings in prestressed concrete, compos-ite or steel construction design. The central construction of the three-stripe Strelasund Crossing between Stralsund and Rgen is the almost 585 m
long Ziegelgraben bridge with its steel pylon that is 128 m in height and the harp-shaped angular rope suspension. Individual construction ele-ments were lifted in, welded with free collars and hooked back into the rising pylon using one pair of ropes each. At the same time, the load was returned from the pylon via a
pair of ropes to the previous field, where the increasing back-hanging forces were absorbed via ballast concrete. Tension sequences and tension force were chosen in such a way that reten sioning was not necessary after the bridge had been finished and adjusted themselves to the regular cable forces.

Nijmegen City Bridge
With one of Europes largest steel arch bridges the De Oversteek 1,825 m long bridge section links the west-ern part of Nijmegen to the industrial district of De Waalsprong. With its impos-ing network structure consist-ing of 7,000 t of steel, the river bridge spans over the 285 m long Rhine waterway, which is called Waal in Dutch. Roughly 17 km long and up to 160 t heavy steel arches were welded on an assembly plat-form on site to assemble the
Pedestrian and cycle path bridge in Weil on the Rhine
With a span of almost 250 m, the new Rhine bridge between Weil on the Rhine and the Alsa-tian town of Huningue ranks among the worldwide biggest pedestrian bridges. The bridge construction that is a symmetric in the cross-section consists of a vertical arch as the main sup-port element which is made up of two hexagonal, welded box sections. The southern arch made of circular tubes rests
against the northern arch with an inclination of 16. The steel superstructure was mounted on a pre-assembly site on the French side and then trans-ported one kilometre upriver using pontoons by closing off shipping traffic. After a turn of approx. 90 the bridge struc-ture, almost 1,000 t heavy, was floated in and set accurately on the counter bearings on both sides of the bank.

60 m high arch bridge. The pre-assembled arches were then lifted into their final posi-tion in two steps using strand-jacks and a 70 m high gantry support in the middle of the bridge. Two 55 m high auxilia-ry supports were also used to bear the arch forks and assem-ble all the steel arches. The arch structure arrived by water with the help of two floating pontoons over a period of ten hours when the river was blocked for shipping.

IJssel bridge, Netherlands
The new railway and cycle bridge crosses the River IJssel near Zwolle as an important part of the new 50 km Hanzelijn route, replacing another bridge from the 1930s 50 m further north. The two foreshore bridges and one river bridge, of a total length of 926 m and a total tonnage of 9,900, required more than one assembly process. While the foreshore bridges main supports were lifted in field by field, the 2,200 t truss of the river bridge had to be pre-assembled at a separate place near the riverbank. After their completion, the 135 m long central part was floated into position by means of winches and pusher tugs and lifted into position with strand jacks.

Hybrid Wind Power Towers
With taller towers, larger rotor diameters and more than three MW nominal power, a new generation of wind turbine generator systems is coming onto the market. The Max Bgl Group has now successfully entered the renewable energy market, too, by building the first hybrid wind turbine tow-ers near Hannover and by putting on stream Bavarias currently most efficient wind turbine of the 3MW class on the Winnberg in the Neumarkt district.
Based upon the Max Bgl Groups huge expertise in the design and production of very precise pre-cast concrete components, in conjunction with the steel construction and plant building division a hybrid
tower was developed that is a combination of pre-cast con-crete components and steel components for the top of the tower. The production of the adapter pieces to be placed between the concrete-only part and the steel top took place in the specially equipped Sengenthal steel construction plant. With the mill and drill centers there, Max Bgl could guarantee that the very precise customer specifications regard-ing both the pre-cast concrete components and the steel com-ponents would be met. This combination of concrete and steel, coupled with the most precise workmanship, allows hub heights of 100 to 150 m, at a total height includ-ing the rotor of up to 200 m.
