The Hess factor – Top Technology


Hess, a Top Werk company, offers German machines equipped with top-class technology from its Indian facility for sustainable road and rail networks.



A German conglomerate, having its presence in India since the last four years, HESS Machinery Ltd has been delivering its expertise in the manufacturing of concrete production equipments to cater a wide range of construction activities. Known for its technical supremacy, Hess has been a frontrunner in the reforming the path of construction. Roads and railways are two such vital construction areas wherein Hess offers its technical expertise, particularly in addressing the urge for reforming transportation networks as per the demands of exploding population. Hess India’s Forest Press Machine, a wet cast press machine manufactured through a joint initiative with Forest Press from UK is one such technology that ensures to meet the dire need for refining the construction of transport networks. The Hess Forest Machine presses concrete in high pressure of 400 tons, extracts water and forms the high density products for different applications. Dosing and take off’s are specially designed to produce high quality concrete products by the wet mix process. The Superior quality in concrete products ensures a longer life and retention of the excellent surface finish of the product. The high pressure exerted during the operation also enables the product to be highly wear resistant and also reduce water-absorption and frost damage. The on-site installation process and fully automated features enables the machine to surpass the concerns of availability of skilled labour and cost effectiveness.






Owing to the speed and ease in usage, rivers were often considered as a much preferred transport network in the ancient times. The advancements in technology and need to establish divergent transport routes evolved roadways and railways as two prime modes of passenger and freight movements. The Romans were the pioneers to set the reformation with the construction of stone paved roads, in North Africa and Europe, primarily to support their military operations. The saga of road construction which was initiated by the Romans was taken ahead by the Arabs who built roads covered with tar. The roads were constructed by preparing earthworks and lifting the road foundation at the center for water drainage. The advancements in technology gradually refined and improved the road construction process. The later eras witnessed road construction being focused upon wide range of factors like – traffic, stone thickness, alignment, slope gradients etc.




Shift in material usage


A rather refined approach is also being noticed in the usage of raw materials for construction process. While the initial construction materials involved stones laid in a regular, compact design, and covered with smaller stones to produce a solid layer; the modern day process comprises the removal of geographic obstacles, and the use of new construction materials that are far more improved and durable. Rock and earth is removed by explosion or digging. Embankments, tunnels, and bridges are constructed, and then vegetation is removed by deforestation, if necessary. Finally, the pavement material is laid by using a range of road construction equipment.The latest road construction includes not only the main paving area but walkways, drainage systems and cablings, which are also parts of it. The usage of effective raw materials hence is of prime importance.



Managing construction


With ever increasing traffic and exponentially increasing vehicular load, construction management techniques are of vital importance. Managing maximum traffic in optimal space is what the world needs today. Safe designing of roads, highway space management and proper drainage of water are major aspects that the site engineers have to handle. Construction management includes putting all the pieces of puzzle together, defining project objectives, dividing the project into modules and optimizing the available resources. Time, money and resource management are important aspects. Time saved is money earned, and that is where construction management techniques are helpful. To achieve this right product and right system needs to be implemented in the right method.


The latest road construction includes not only the main paving area but the walkways, drainage systems and cablings are also parts of it. Proper design with right materials which are economical, easier to build and able to give durability within the stipulated time frame is important. It’s always a debatable topic in India where we have road institutes and governmental departments doing a lot of things and still a lot to achieve. The basic problems remain due to several reasons but the excuse is not an option every time. So this may be the time the concerned authorities should take it seriously to come out of the right solution which suits to different parts of India. Anyway the situation is changing with the government inviting private players and foreign investors to create a better infrastructure.




Road blocks


Technological advancements though has scaled up the construction activities, a dire need exists to reform the process in building roads. This need has to be immediately addressed in countries like India which is facing the growing concern of exploding population. Also, the age old construction practice which was being followed since the British regime needs to be transformed to suit the present-day conditions. Today, the population has increased and so has the economic activities in India. Roadways are basically designed and constructed for the use by vehicles and pedestrians. Hence, roads which are being constructed should be able to sustain the rise in passenger and freight traffic (in terms of frequency and size). Effective planning and adoption of qualitative construction management services is required to improve the load baring capacity of the roadways being built. Sustainable roads are a must to even fulfill our Prime Minister’s and Government’s aim to develop 100 Smart Cities and such futuristic initiatives. The road construction projects being allotted in India most often involve the development or building of stretches varying from 10 – 500 km. Roads can be built through multiple methods with different construction materials and systems, each having both advantages and disadvantages that depend on numerous factors. A basic study on the climatic conditions, geography and topographical layout, availability of material, identifying best technology and economic implementation can evidently enhance the mode of construction process. In a vast country like India if we proceed with the age old methods and materials to construct roads it will not be feasible and durable in most of the cases. Finance, durability and time will be other factors which the concerned authorities need to consider before adopting a particular system suitable for each location. Actually the concerned departments are well aware of these factors but due to certain personal gains or pressure they follow wrong methods. Apart from these factors, drainage and ecological considerations are the other elements which need to be considered seriously. Today construction has become more complex. Nowadays the road construction is together with water flow arrangement, electric cable lying, info cables, cycling track and walk ways. The right technology and products will help in speed up the construction. Sediments and erosion are controlled to avoid damaging effects. Drainage systems are constructed so that they should be able to carry waste water for processing and further use. Road construction and engineering includes planning, designing, and building of highways.



Earthwork is one of the major works involved in road construction. This process includes excavation, material removal, filling, compaction, and construction. Moisture content is controlled, and compaction is done according to standard design procedures. Normally, rock explosion at the road bed is not encouraged. While filling a depression to reach the road level, the original bed is flattened after the removal of the topsoil. The fill layer is distributed and compacted to the designed specifications. This procedure is repeated until the compaction desired is reached. The fill material should not contain organic elements, and possess a low index of plasticity. Fill material can include gravel and decomposed rocks of a particular size, but should not consist of huge clay lumps. Sand clay can be used. The area is considered to be adequately compacted when the roller movement does not create a noticeable deformation. The road surface finish is reliant on the economic aspects, and the estimated usage.
Bulldozers are extremely useful for road construction where it is possible to throw the waste excavated material on the road sides. Bulldozers may only be used if the slopes at the sides are not excessively steep. However, work on steep slopes can be accomplished by a bulldozer by using special techniques and expertise.




HESS Solution


The strong global experience and technical expertise, HESS Group today has the potential to address these evolving concerns being faced in Indian road construction projects. The wide range of automated and technically superior products like Forest Press Machines and Prinzing Pfeiffer has enabled road construction in challenging conditions which is no more a difficult task. For instance, the Single Press Machine under the HFP range through the use of wet-mix process ensures a longer life and retention of excellent surface finish for the structure. The high pressure exerted during the operation gives an extremely dense product with high strength and good wearing qualities. This high density together with the fine surface reduces water absorption and makes the surface even resistant to frost damage. The product can effectively address the common problem of water clogging and de-gradation of road surface being faced in India during monsoons. Furthermore, construction will be faster, smoother and of high quality with the usage of u-channels, slabs, kerb stones and dish channels. Also, the usage of recyclable materials for the construction of roads has added balance to the environment too. Maintenance is no more a difficult task with the right application of binding agents and admixtures, making the road more sustainable and durable in nature.


However a change in the attitude and mind-set of public and governing authorities is an utmost necessity. Addressing the most discussed and crucial worry of corruption is also a matter of grave importance. As per the past experiences and observations, often a section of officials prefers to do road work and maintenance every year, mostly for their personal benefits. However, with the new government coming into force and departments being more focused we are hopeful that the right attention will be given to the top technology, which will ultimately allow Indians to have better infrastructure.






The development of railway is expected to get a shot in the arm with a new government at the Centre and a forward thinking Prime Minister at the helm. The Indian Railways is gearing up for major development in areas like modernisation of tracks, trains, stations and others. It will need regular additions and maintenance to the existing 8000 plus stations and platforms. The Indian Railways count among the largest in the world in terms of track length, stations, platforms as well as goods and people movement. The foundation for road and rail networks were designed and implemented during the rule of British Need a major revamp at this time.




Key Barriers


Today with a dramatic rise in rail movement the country is placed in a different situation since facilities are not equipped to withstand the pressure.  Not only the design and implementation of both metros and standard stations separate, they need completely different mechanisms.  There is a growing need for a durable system which addresses issues like time, cost and easy implementation all over India. For getting such structures and systems into place the latest products and technology including heavy cranes and accessories are required. Currently the technocrats are not serious about proper planning, right products and a cost effective system which works on a time schedule. Hence, the mindset needs to change to capture the speed of development. The current government, as it appears, is serious about the reformation process – as seen from the placement of people like Suresh Prabhu as Union Minister for Railways and E Sreedharan as Advisor to speed up the process and implementation. Having the right people at the right place will prove to be beneficial for the railways and the people of India.


A major transformation is needed in the practice of construction for rail infrastructure. We are still dependent on the British era old construction mode and have old stations with creaky infrastructure. With India having the longest rail network and more than 8000 stations with each station even having multiple platforms, usage of right technology and right products are need of the hour. The technologies and products being adopted worldwide needs to be implemented in India, which can benefit the construction process in terms of cost, durability, better face lift and easy implementation. Also, the authorities need to look at professional players instead of depending on unorganized sectors.




Action Station


Hess is one of the leading technology providers under the brand name Prinzing Pfeiffer, which even prepares railway sleepers for different rail segments. Apart from sleepers the railway stations too need urgent attention. A normal platform is made out of roofing, base slabs, edge slabs, steps, u-channels, dish channels and others. The main reasons to use such elements are to ensure that the platform is built within a short period of time at best quality with standardized products. It will also help remove rain water from the station and make it easier for physically challenged people to navigate. The Hess Forest Press Hydraulic Wet Cast system can produce all these items out of one machine which can easily be shifted from one place to another. Nowadays most of the stations have started to use ceramic and clay tiles in stations which are easy to break on heavy loads and slippery during rains. Sadly enough rail stations like Pune have used rubber moulded pavers which do not have proper strength to support man or material movement. Secondly the implementation is completely wrong which results in loss of public funds, time and troubles. Newly-installed paver blocks worth `80 lakh on platform 6 of the station to accommodate 22 coach trains came undone within six months, highlighting the shoddy workmanship by the authorities. Considering the amount of goods and people movement in the station wet cast products such as offered by Hess offer the right solution.
