EDITOR’S NOTE

CONSTRUCTIONWEEK VOLUME 9 • ISSUE 10 • JUNE 2018

in tough vein Jayashree Mendes

Mitalee Kurdekar

B

ureaucrats and heads of PSUs in India can be interesting. Considering that they are handpicked, vetted, and offered plump posts whose only redeeming quality is that they are expected to stay in the shadows and implement decisions.

In the last one month, I met two significant gentlemen — both heading government organisations.

There’s a certain kind of expectation when one is meeting a person for the first time. Both of them surprised me. They may not be celebrated, but they effortlessly segue between goverment officials and the public. For instance, Narendra Nath Sinha, MD, NHIDCL, and our cover person this month, appears reticent and taciturn at first glance, but prompt him to speak and you realise that here’s a person who knows his job and how he needs to go about it. Practically living on the frontier, Sinha can go from being gentle and soft-spoken to being firm well knowing that he might have to deal with people up in arms against the projects he is executing on the border. He keeps track of the all projects that NHIDCL is executing and cracks the whip on non-performing contractors.

Another interesting person was Anoop Kumar Mittal, CMD, NBCC (India). When you are dealing with government projects worth crores of rupees, you are bound to come up against opposition of some kind. Mittal is the man who has expectations from the government and from his clients. Most of the projects that NBCC takes up as PMC are often embroiled in some disagreement.

But he knows that if his company has to show profits, work has got to be done. He ensures that budget numbers add up, the company gets its fair share of commission from the project and he remains hawk-eyed on project cost.

Indeed, these gentlemen are assets to the government given their long experience.

U

S

nion Home Minister Rajnath Singh has laid the foundation stone for the redevelopment of Gomti Nagar and Charbagh railway stations in Lucknow.

The redevelopment project is being executed by NBCC (India), a Navratna CPSE under the Ministry of Housing and Urban Affairs (MoHUA), Government of India.

NBCC has been entrusted with the redevelopment of 10 railway stations across India. The other dignitaries who were present during the ceremony were Piyush Goyal, Union Railway and Coal Minister, and Dr Anoop Kumar Mittal, CMD, NBCC. The redevelopment of these railway stations shall be carried out in phases and the estimated project cost of Phase 1 is approximately Rs 374 crore and Rs 1,206 crore for Gomti Nagar and Charbagh respectively. NBCC shall be executing this project on a self-revenue generation model by commercial utilisation of vacant railway land parcels.

NBCC, which has wide experience in constructing and developing modern day infrastructure, will carry out the redevelopment of these railway stations on the lines of smart development to enhance passenger amenities, create congestion-free station premises, seamless integration with other modes of transport and passenger friendly services; while incorporating green building and energy-efficient features.

CENTRAL GOVERNMENT TO BUILD 45KMS OF ROADS PER DAY: GADKARI

CREDAI BECOMES THE DIRECT TRAINING PARTNER OF NSDC

he Central Government has raised their daily target for roads and highways construction to 45kms of roads per day in FY 2019-20. The target was set by the Road Transport and Highways Ministry, and is a sharp rise from the 2017-18 achieved figure of around 27kms a day. In addition, the ministry is also set to award 20,000kms worth of national highway projects in 2018-19, and aims to achieve a construction target of 16,420kms, according to Union Minister for Road Transport, Highways and Water Resources, Nitin Gadkari.

The ministry has plans for a complete expansion of its capacity, which calls for an investment of close to Rs 2 lakh crore.

REDAI’s Skill Development Programme has trained more than 1 lakh construction workers since 2011. Now, the National Skill Development Corporation (NSDC) has enlisted CREDAI as its partner. The partnership would enable CREDAI to conduct skill training of construction workers across the nation through access to CSR funds available with NSDC for skill development. The two organisations will work together with the aim of increasing employability and skill development of construction workers. CREDAI aims to train 1 lakh construction workers over the next three years through various skill development programmes by NSDC.

TEETHING TROUBLES

RERA may need another 12- 18 months to be fully implemented, believes Ramesh Nair.

The author is CEO and country head, JLL India.

20 CONSTRUCTION WEEK JUNE 2018

W

hile the implementation of RERA has been below target, it has indeed seen positive steps forward. The achievements of the past year should be seen in the light of the fact that previously, there were no regulations for the sector. RERA brought about a paradigm shift in the real estate landscape of the country. We had all hoped that it would be enforced within the time limit set by the government, but it would have been an uphill task to enforce it in a short window of a few months.

However, the commitment from various state authorities looks promising. We believe that RERA will come to force across the country, soon. Predictably in the next 12-18 months, all the states and union territories should be able to establish their respective permanent regulators. One of the aspects that the central government should look into to make RERA impactful is align the Insolvency and Bankruptcy Code to it, creating a proper option for the exit of development companies.

On the first anniversary of RERA, the implementation across states is nowhere close to its goal. As of April 2018, only 19 states and union territories have an online portal in place, and five states and union territories have a permanent real estate regulatory authority. So far 27,000 projects are registered under RERA across various states, while 17,000 agents are registered under RERA. The primary objective of RERA was to ensure that an end-user of real estate is better protected by bringing in transparency into the sector.

Buyers have welcomed RERA as it protects their purchase in real estate by providing a dedicated tribunal for addressing their concerns. Buyers have also appreciated the sense of empower-

ment it brings as the information asymmetry is reduced, thus helping buyers in taking appropriate decisions. RERA has been welcomed by developers in most cases as this being a straight forward ruling, adherence has been high. Further, it has ensured that developers complete the due process as required by the law before launching their projects.

Going forward, RERA will create the muchneeded transparency in the real estate sector. A well-governed and transparent system will allow the sector to grow and contribute positively towards economic growth. This will also allow the real estate sector to attract investments from institutions. The implementation of RERA would be good for the banking sector, helping them evaluate projects prior to extending loans and mortgages. For home buyers, it will ensure that their capital in real estate is protected and that they receive the product they have paid for. All of this will increase the overall market confidence and eventually sales velocity in the sector.

Of the various states where RERA has been implemented, Maharashtra has shown good results. Maharashtra has recorded the highest number of registered projects – estimated to be 16,000. MahaRERA has been active in redressing customer complaints and queries. MahaRERA has empowered and protected consumers and, at the same time, has given comfort to developers for being fair to all. It has also helped in the settling of disputes mutually between parties, thus showing the way to other RERAs about being practical and proactive. The icing on the cake will be introduction of a single-window clearance or taking steps to address the time spent in seeking approvals from the local corporation and government agencies.

THE SENTINEL

As custodian of infrastructure development in the North and North-East border, Nagendra Nath Sinha, MD, NHIDCL, faces myriad issues. He knows how to deal with them.

BY JAYASHREE KINI MENDES

S

peak softly and carry a big stick, is an adage we have all heard quite often. It is quite useful when you are leading the charge of building infrastructure that involves roads & highways, and tunnels that require high engineering expertise. Not just ordinary roads and tunnels, but infrastructure that is rife with claims and clearances, not to forget surreptitious attacks that marks the international borders crucial to the country. Nagendra Nath Sinha, MD, National Highways and Infrastructure Development Corporation (NHIDCL), has his work cut out for him. In a tête-à-tête with Construction Week, the soft-spoken Sinha with a gentle demeanour reveals why building roads in the North East and other states bordering neighbouring countries is not an easy task. It handles projects in all the North Eastern states like Tripura, Assam, Manipur, Meghalaya, Arunachal Pradesh, Andaman & Nicobar, Jammu & Kashmir, Uttarakhand, Himachal Pradesh and West Bengal.

When NHIDCL was set up in 2014 under the Ministry of Road Transport & Highways, it was given the mandate to promote, survey, establish, design, build, operate, maintain and upgrade National Highways and strategic roads including interconnecting roads in parts of the country which share international boundaries with neighbouring countries. The organisation is involved in the construction of roads in the border districts along the international borders and the Line of Actual Control (LAC), which is also overseen by the Defence Ministry and the Home Ministry. It was a task that was earlier done by the Border Roads Organisation (BRO). Over the last few years, several thousands of kilometres of roads have been transferred from the BRO and other organisations and handed over to NHIDCL, thus enabling the Ministry to complete the work on time and help the country improve

connectivity and forcing other agencies to do their core work.

Sinha says, “When I joined in August last year, there was only seven months left to the financial year. Few projects had been sanctioned and we were left with a large chunk of targets that needed to be awarded as well as completing ongoing construction. There was also the issue of delegation of authority to sanction projects. The projects under execution had been sanctioned by the Ministry and we had to persuade the Ministry to define a streamlined protocol for approving the new projects so that they could be awarded and work could begin. I am happy to tell you that we were able to award over 1,000kms of new roads. Besides this, we also completed about 600kms of highways, and a feather in our cap was awarding the country’s longest tunnel project, Zojila, which has a length of about 14.2kms.”

TIES THAT BIND Working in remote locations at high altitudes and deep forests calls for a certain grit and determination. For long, India’s periphery has been prone to attacks and this has only

strengthened the government’s resolve to fortify its borders.

The idea is to allow the Army and citizens to move easily from town to town, be it for vigilance purpose or to do business.

It’s for this reason that NHIDCL anticipates creating customised and specialised skills in terms of addressing issues like complexities of geographical terrains and extensive coordination requirements with State Governments and security agencies. The organisation has the approvals of the Environment Ministry who extends a general approval for diverting forest land to build infrastructure, which is applicable for road construction and other infrastructure within 100kms of LAC, 15kms of Indo-Nepal border, 16kms of Indo-Myanmar border and 5kms from all other international borders.

Arunachal Pradesh is the largest portfolio currently in NHIDCL’s kitty with 1,000km of roads and Rs 14,000 crore investment. Sinha says, “We are building certain stretches of the Transkms of roads to be Arunachal highway which is about developed by 2022.

1,800km long and runs in the South of the state and then along the river valleys we are building a stretch of 175km roads along Joram-Koloriang (120kms). Besides that, we are constructing Akajam-Likabali-Bame (83kms), Roing Hunli Anini (184kms), Brahmkund Hayuliang-Hawai highway (120kms), and the

Pasighat-Pangin road (45kms).” NHIDCL also has the overall mandate to construct an overall 10,000kms of roads by 2022 for which it is inching to prepare and close the DPRs by 2019.

The roads are along the valleys of Arunachal Pradesh which will connect with the ambitious Trans-Arunachal highway.

In its biggest challenge yet, NHIDCL will construct the 14.2km long, 2-lane bi-directional Zojila tunnel at an estimated cost of Rs 6,809 crore. The government body has signed an MoU with IL&FS Transportation for its construction. The

tunnel will provide all-weather connectivity between Srinagar, Kargil and Leh. On completion, the tunnel is expected to be an engineering marvel and a first-of-its-kind in such geographical terrain. It will have modern technical safety arrangements such as cut-and-cross ventilation system, fully transverse ventilation system, uninterrupted power supply, CCTV monitoring, variable messaging boards, traffic logging equipment, tunnel radio, emergency telephone system, etc.

IL&FS is responsible for construction, operation and maintenance of the tunnel on an EPC basis.

Technology plays a paramount role in the initial stages of DPR, procurement and tunnelling. “We use technologies intensively across various stages. In the DPR preparation stage, we use LIDAR; in tunnel DPR we would like to deploy aerial electromagnetic survey method, and similarly, we’re thinking of using horizontal directional coring for unearthing geological and geotechnical status of the alignment,” adds Sinha.

NHIDCL refrains from specifying the technology for construction and leaves it to the contractor to choose any technology permitted by the Indian Road Congress. “However, in certain cases we have allowed them to use stabilisers so as to bring down the requirement of aggregates,” says Sinha.

MAKING THE MARK What gives Sinha a sense of pride is his team’s prompt response to the government’s decision to complete detailed project reports (DPRs) of complicated projects much before the deadline. “We’ve substantially completed the DPR of large projects such as the Dhubri Phulbari project, and have started

tions. Two years ago, the organisation had designed and launched INAM-Pro, a web portal to bring cement buyers and sellers together. The portal facilitated comparison of price, availability of materials, and made it convenient for prospective buyers to procure cement at reasonable prices. Following the success, the portal has recently been upgraded to INAMPro+ and includes the A to Z of construction materials, equipment/machinery and services like purchase/hiring/lease of new/used products and services in the domains of construction materials (steel, bitumen, aggregates, paint, etc), infrastructure machinery, Intelligent Transport System Equipment, road furniture, haulage vehicles, among other things, that go into road building. The publicly visible prices have promoted transparency and enhanced ease of doing business. The Corporation has also persuaded the Ministry and developed a software for evaluating contractors’ contracts through BIMS, which will soon be mandatory from June.

Sinha feels that NHIDCL should adopt technologies like drones and artificial intelligence so that they are able to predict events and traffic projections more accurately. He is keen to adopt technology that will aid in quick maintenance of highways thus reducing wear and tear and inconvenience to the commuters.

bilisation, fragile hills, flood mitigation, etc. Specialised engineers are roped in from outside the Corporation to complete and hand over a final report before work can begin.

Road construction also involves building bridges and currently several large bridges are being constructed over the Brahmaputra river. One such bridge is between Dolabari and Kaliabor-Tiniali, which is parallel to an existing bridge. Engineering work is in full swing for another 20km long bridge between Dhubri in Assam and Phulbari in Meghalaya. This would supposedly be the longest bridge, of which 10km

would be over the river and another 10km on floodplains.

A conscientious decision that the Ministry insists upon and NHIDCL has vowed to do is ensure 90% land acquisition before awarding projects to contractors. The Ministry also insists that NHIDCL push the envelope and complete 80% land acquisition before approaching the Ministry for clearances.

Sinha says, “A major challenge before us is the issue of land acquisition. The land records in the states where we work is highly unsystematic like many of the mainland states. In certain states, the records are not only deficient, but non-existent and sometimes maintained by the community headmen.”

Other challenges come from state governments and the authorities there. The local governments are known to hold their ground for verifications and this can put a spanner in the works, thus delaying the approval process. Disputes on rates of compensation from landowners can also delay approvals.

Sinha is glad that NHIDCL is better placed than other agencies as currently all the new projects have been taken on EPC basis. “The costs are defined and payments are made on the stages of construction. Hence, cost overruns do not figure here much, as the contractor is expected to finish the project in a certain period of time. Non-conformity to this will mean a termination of contract or an extension of time but no additional sums than pre-decided. Only when contracts are terminated because of insufficient progress are we compelled to incur cost overruns,” he adds. It is for this reason that NHIDCL keeps a sharp eye on progress and cost.

Ask Sinha about where he foresees the Corporation a few years down the line, and he says, “While this organisation must fulfil the infrastructure part of its mandate, we would like to build airports, logistic parks, jetties, wayside amenities, etc. Incidentally, we will undertake responsibility of one of the multi-modal logistics hub, being undertaken by the Ministry under Bharatmala.”

In his benevolence, he airs his views on the areas that NHIDCL could improve on in terms of completing projects on time and improving connectivity to different parts of the border. “I would like to work on exchange of thoughts, ideas, good community services to the mainland and border areas and ensure fullest possible integration with the nation.”

With a smile and closing the interview, Sinha says that the issue of militancy has partly risen because country has not fared very well in improving connectivity to populations on its borders. Improving the quality of access will bring about social cohesion and natural integration.

GREEN CONSTRUCTION

THE RETROFIT REVOLUTION There are several myths surrounding green construction. But developers and vendors alike are looking at breaking through this to make for sustainable living.

T

he world is paying the price for rapid urbanisation and massive population increase in the quest for faster economic growth. Over the last few decades alone, we have depleted our natural resources because of the dynamics of urbanisation that has misused these resources. The alarming rise in greenhouse gas emissions, climatic changes, waste generation, have resulted in continuous environmental degradation.

It is only in the last few years that the industry across sectors have woken up to the fact that they need to save the planet.

Environmentalists abound and much of their cries have trickled down to the hoi polloi.

The lifecycle of a development from demolition to construction to operation consumes a number of key resources such as energy, water, raw materials, among others. In order to achieve economical resource consumption certain best practice processes and undertaking key initiatives during the development phase is most important. The implementation of these initiatives/processes that help track and manage resource consumption in projects will be important to ensure

efficiency in the utilisation of natural resources during the development phase.

Vivek Mohanani, MD & CEO, Ekta World, says, “The climate change and global warming is compelling the real estate sector to find ways of constructing green buildings that are affordable to all. If the intention is to construct a green building, it is advisable to build, rather than work on an existing one. The cost may vary but overall green construction offers 12% operational savings and 7% assets value appreciation as compared to conventional buildings. Sometimes green technology appears expensive because they are new or seem complicated, but their gains are long term.”

Considering India’s growing population, “government initiatives such as smart cities can aid in an increase in affordable housing units and a concerted push towards infrastructure development, while conserving natural resources, becomes critical during development. This can be achieved by greater regulatory support promoting environmentfriendly development and a focus on developing green buildings”, says Shubika Bilkha, director, Real Estate Manage-

ment Institute (REMI). She believes that with increased focus on sustainable development, developers should look at incorporating ecofriendly substitutes for construction. Some new green materials that have been used for construction include fibre cement siding, thermally modified wood, roof shingles, plywood veneers and natural stone tile. Additionally, some affordable green materials include bamboo, wood, recycled metal and plastic, structural insulated panels, cellulose and natural clay plaster.

NEW OFFERINGS In the construction industry, vendors too are enthusiastic about offering eco-friendly materials and equipment that can help develop sustainable buildings. VG Sakthikumar, MD, Schwing Stetter Sales & Services; convenor for membership committee, ICEMA; and chairman of mechanisation committee, BAI, says, “Though we are a part of the construction industry, our focused area is building machines that can meet customer’s expectations. We have designed machines looking beyond the performance and considered critical issues like fuel consumption, noise pollution, recyclable parts, long life of equipment, etc., which can play its own role in conservation of resources.” Schwing Stetter believes that conserving water is one of the critical requirements. “Concrete recycling plant will use the leftover concrete, waste con-

crete, washed water, etc. and make it possible to reuse them in concrete production. Washed water with the cement content can pollute not only the surface water but also groundwater which is a serious concern,” he adds.

Giving an insight into products, Mahesh S Anand, president, Nippon Paint (India), says, “We ensure all our paint products are environment-friendly, and were one of the pioneers, even in the international market, to introduce non-toxic, anti-formaldehyde wall emulsions that have near-zero VOC and are odourless by nature. These emulsions, apart from having high durability, also absorb harmful airpolluting vapours that cause health hazards, and convert them into clean fresh air, thereby ensuring a clean environment around us.”

Indian builders are slowly embracing the idea of eco-friendly construction. They need to first have a sound knowledge of green technology and ways of incorporating it in projects. “A good way to start would be to employ energy efficient methods like solar panels, rain water harvesting, green materials (wood, stone, earth) and other recycled materials (recovered wood and concrete, fly ash cement) in construction. Landscaping, terrace and vertical gardens minimise air pollution, also conserving energy and water consumption. The ultimate objective of a green architect is to safeguard resources and choose eco-friendly materials and construction practices,” adds Anand.

Speaking of concrete, Atul Desai, ED & CEO, RMC (India), a division of Prism Johnson, says, “We have multiple eco-friendly special concrete products such as Elitecrete, Perviouscrete, Envirocrete, and Megacrete, which reduce carbon footprints, conserve natural resources and can be recycled. Concrete being a technically advanced solution involves high intellectual property for R&D of green products.

Green products are differentiated in raw material selection (locally available), manufacturing process (energy conservation), sustainable delivery mechanism and the properties to conserve the natural resources for generations.”

PLAYING A ROLE Maintenance of green buildings is not different from conventional buildings. Green materials are safer for the occupants and reduces their maintenance costs. Ashish Raheja, MD, Raheja Universal, says, “When starting a project, we envisage the materials we are going to use and source. We ensure that we source construc-

tion materials from nearest location of the site, make maximum use of recycled material like fly ash bricks and RMC.” On its part, Rustomjee has adopted green and eco-friendly construction as an intrinsic philosophy. Atul Date, head, design, Rustomjee Group, says, “Materials are finalised considering the tenets of function (durability, applicability of context and persistent intended usage) along with aesthetic aspects. We experiment with a lot with new materials & technologies with an in-depth amount of R&D that precedes actual adoption. Some key materials are AAC blocks, performance glass, water saving plumbing fixtures & fittings, LED fixtures for lighting, use of flyash in concrete, engineered wood for door frames, and uPVC for enhanced acoustic/thermal performance.”

Explaining the factors that matter to them, Jaswinder Sandhu, executive VP, EPC, Oberoi Realty, says, “When we talk about eco-friendly materials, we expect it to be from a renewable source and should be biodegradable, recyclable, aid energy efficiency, increase durability and life span, reduce air, land and water pollution, and should be available. We should be able to reuse the waste products, and the material should have energy conservation properties, and must embody energy. Initially, it was a challenge to identify ecofriendly materials, however, with continuous use and help from our LEED consultants, we have good control on sourcing.

ROADS & HIGHWAYS

ROAD TEST

With an enviable programme in place for expanding India’s roads & highways network, the Government has set the ball rolling. But the true test lies in ensuring purposeful execution.

ndia boasts of the world’s second largest road network, and given the length and breadth of the country, this is no surprise. With an expanse of 5.4 million kms, Indian roads support the ferrying of more than 60% of goods and 80% of people movement across the remotest corners of the country. However, what is astonishing is

44 CONSTRUCTION WEEK JUNE 2018

that Indian roads carry such stupendous loads despite having poor conditions and unsatisfactory road management.

Therefore, although the feat achieved is great, it also means that we are incurring costs arising from the wastage of resources, including scarce, imported fuel. It is therefore heartening that the Government of India has taken it upon itself

ROADS & HIGHWAYS

to pursue projects that would result in changing the face of Indian roads in the coming 5-10 years. Does that mean that the issues that plagued such infrastructure projects have just evaporated? The answer is both no and yes. While issues such as land acquisition, red tape, resource crunch, lack of skill sets & technology, and more importantly the absence of co-ordination between agencies continues to hamper progress, industry players now approach projects differently, and try to resolve these issues up front with the help of an resolute intent and firm plans in the form of DPRs (detailed project reports).

The development of roads & highways has been a focus area for the Indian Government as it tries to realise its objective of all-round economic development. On the other hand, the Ministry of Road Transport and Highways has set a goal before it of building at least 90,000 kms of highway network during the course of its current term to take the length of Indian highways to an ambitious target of 2 lakh kms. The transport infrastructure of India is expected to grow by around 6% in quantum terms in the next 3-4 years, thereby becoming one of the fastest growing infrastructure components of this vast economy.

EXCITING JOURNEY AHEAD Of course, key players involved with this industry are euphoric about the development of such plans and supportive policies announced by the Government from time to time.

As Amit Uplenchwar, CEO, HCC E&C Business, states, “With infrastructure development being a high priority sector in

ROADS & HIGHWAYS

NHIDCL has played a leading role in bringing technologies, particularly IT technologies for the highways segment, into play.

India, we see a lot of potential in the road segment over the next five years. This will continue to be an area of focus for us.” Uplenchwar continues, “India’s roads & highways segment has very high potential and will continue to attract maximum investments. The Government of India has announced the Bharatmala Pariyojana Scheme under which Rs 8,00,000 crore worth of roads will be built over the next five years. Bharatmala is a new umbrella programme for the highways sector that focuses on optimising the efficiency of road traffic movement across the country by bridging critical infrastructure gaps.”

Devendra Jain, ED & CEO, Dilip Buildcon, puts the industry’s enthusiasm in perspective when he says, “It’s a very exciting time for the roads & highway segment, now more than ever before. This becomes evident if you just look at all the data available. The Government has articulated a five-year vision through the Bharatmala Pariyojana. They have identified the roads that they want to build, where they are going to secure the funds to do so, how much of this is going to come through the government budget and how much extra funding is necessary. The Government has been doing a lot to identify the economic corridors. It has identified border roads. Therefore, it has a very holistic plan. In fact, the entire approach now is to build corridors, rather than doing smaller patches of roads across the country.”

As a matter of fact, the nation is now seeing the development of roads & highways even in far flung regions like border areas, which are typically quite hilly terrains, particularly those in the North and Northeast regions of the country, where climatic, geological, and law & order conditions are difficult to face when it comes to road building activities. In

NHI IS NOW FOCUSING ITS EFFORTS ON THE NON-BORDER STATES, WHILE WE AT NHIDCL WORK IN THE BORDER STATES. NAGENDRA NATH SINHA fact, the Indian Government has set up a new organisation by the name of National Highways Infrastructure Development Corporation Ltd (NHIDCL) under the Ministry of Road Transport and Highways.

Nagendra Nath Sinha, MD, NHIDCL, is upbeat on this focussed initiative on the part of the Indian Government. He explains, “NHI (National Highways Infrastructure) is now focusing its efforts on the non-border states, while we at NHIDCL work in the border states. Border states are typically hill states and they have issues like building a large number of tunnel projects. We have to deal with these issues of hill roads, where drainage problems are a serious challenge.

Similarly, slope stabilisation has to be planned as these hills in the Himalayan region are fragile. Clearances for development in the forest region is yet another issue that needs to dealt with by the Ministry of Environment and Forests.”

ROADS & HIGHWAYS

SMOOTH COORDINATION IS KEY To help matters along, the Ministry of Environment and Forests (MOEF) recently decided to award a general approval for diverting forest land to develop infrastructure along international borders and the Line of Actual Control (LAC) to NHIDCL. As a key EPC contractor, Uplenchwar welcomes this development for contractors like HCC. He confesses

that, “Infrastructure development in the border states has been hampered due to a slower clearance process. This, in turn, affects the ability of the Indian security forces to prepare, mobilise and operate along the border regions. This decision from MOEF is very welcome as this will boost the infrastructure development activity in the border states.”

Sinha professes that the intent is to assist both our army personnel and common citizens in these border areas with ease of movement whether it is for strategic military requirements or for facilitating normal living and carrying out commerce. This is going to be a truly inclusive development for all sections of the Indian populace, wherein people from the remotest corners can now be brought closer together.

Giving another perspective on how this co-ordination is helping smooth planning and implementation, Jain points out that, “The Government agencies have also started work on DPRs for a majority of such infrastructure projects. For a big portion of the Phase-1 projects, there are more than 3,000-4,000 projects. Their DPRs are already ready or in the process of getting ready.”

Jain is confident that this co-ordination would help not only the EPC contractors who work directly on such projects, either on their own or through PPP models, but the ruboff effect would also be witnessed on the downstream sup-

pliers and ancillary units who work on these projects. In this context, he says, “If the government is trying to do so much, it provides an opportunity not just for the EPC contractor, but also for all the ancillary units whether it is cement, bitumen, steel suppliers, etc., who get financial support.”

STREET SMART Above all else, the advent of latest technologies and technical aids has been a heartening feature in the delivery of these large infrastructure projects. Jain points out that the Government is keen to reduce the timelines to deliver on these roads & highways projects to meet their ambitious target. The only way that they can do this is by reducing the timelines for permissions and using the latest technologies, along with remaining in preparedness with impeccable plans and an implementation schedule. “The Government’s endeavour is towards reducing the timelines so that projects can be done within the specified time limits, which is great,” Jain supplies.

Even NHIDCL has implemented many such technologies and been recognised for their technology interventions and

52 CONSTRUCTION WEEK JUNE 2018

IT applications. Sinha explains that they use technologies intensively for different stages. For example, in the DPR preparation stage, they use LIDAR. In fact, NHIDCL has played a leading role in bringing technologies, particularly IT technologies for the highways segment, into play.

Usual challenges of land acquisition due to poor land records and the state government mechanism’s apathy are now overcome with adequate pre-planning with the agencies required to complete 90% of land acquisition before the project hits the ground. Once the laws and rules in this context are settled, the implementation would smoothen further.

As far as manpower availability and skill development are concerned, CSR projects undertaken by corporations like NHIDCL in remote corners like Arunachal Pradesh are exemplary. They act as a catalyst in improving the availability of scarce labour to facilitate project implementation on a fast track.

It now remains to be seen how quickly that actually happens. And that is one test we want the Government to pass with flying colours.

Key impact of cold milling machines on road rehabilitation quality Cold milling is the first measure taken when a roadway needs to be rehabilitated. The condition of the milled surface has a key impact on the quality of the new surface courses, their service qualities and on the economical and efficient execution of other construction measures.

An evenly milled surface, true to line and level, is a crucial factor when it comes to paving surface courses of uniform thickness and avoiding costly correction in the form of asphalt leveling courses.

Market-driven innovations for all applications: Wirtgen offers the most extensive line-up of cold milling machines in the industry, with milling widths of 14mm to 4.40m. Customers can choose from over 30 different machine types, each also available with a variety of milling widths. The lower performance class starts with the small 45-kW milling machines and extends through compact machines with engine outputs of between 257kW and 298kW to large milling machines in the upper performance class offering power reserves of up to 753kW. The high level of customer-oriented design expertise guarantees marketdriven innovations. The new solutions developed at the brand headquarters in Windhagen are founded on practical know-how and core competencies in leveling, control and cutting technology.

Always on the level: A decisive factor in milling a surface true to line and level is precision leveling. The purpose is to regulate the milling depth and slope automatically and precisely based on a reference line.

It has become standard practice to copy an existing surface by scanning a reference line.

But teamed with a range of sensors, the Wirtgen Multiplex leveling system can do more than simple copying. Three sensors on each side of the machine scan the height at wide intervals along the same reference line. The automatic leveling system averages the three measurements to create a perfectly even milled surface, while meeting target milling depth. This is an effective way of leveling out longitudinal undulations.

What is more, defined surface profiles can be created, such as specified cross slopes or crowns.

Completely new surface profiles can be created by means of 3D milling. A new digital surface profile generated on the computer can be transferred directly to the Wirtgen cold milling machine using 3D leveling systems. Increased quality and cost-effectiveness are major benefits offered by 3D milling technology.

54 CONSTRUCTION WEEK JUNE 2018

Milling layers separately, recycling economically: The progressive automation of technical processes plays a key role in optimising the milling result. To achieve optimum results, the leveling parameters for the respective machine are saved, linked to the LEVEL PRO automatic leveling system and retrieved during the working process. Nowadays, the widest variety of pavement layers are removed and separated in selective processes. The removal of problematic construction materials is possible, as is the standard separation of premium-quality surface courses with a high bitumen content, or the removal of road markings prior to the actual separate milling of the asphalt courses. The surface, binder and base courses can be returned separately to the material cycle, increasing the sustainability of RAP recycling.

Selective milling does not entail time disadvantages. Due to the shallower milling depth, the cold milling machines work quickly when removing the individual layers than when removing the pavement at maximum milling depth in a single pass. Milling off surfaces in 2 or 3 layers can sometimes be just as fast – in some cases even faster – than complete pavement removal, depending on the type of machine and pavement and ambient conditions. Modern machines have been tuned to typical selective milling – for example in regard to machine weight.

Cutting technology: A wide range of efficient applications: The powerful “heart” of the cold milling machine – the milling drum assembly with all the cutting technology components – also has a bearing on the quality, costs and performance of the process. Here, too, Wirtgen is developing cost-efficient solutions. Different milling drums support a wide range of milling applications on different road surfaces.

The standard milling drums offer tool spacings of 12-, 15- or 18mm.

Fine milling drums usually have a tool spacing of 8mm; in micro-fine milling drums the tooling space is 6mm. The ECO Cutter milling drums developed by Wirtgen are designed for maximum milling output. They can even mill extremely hard materials such as concrete or rock cost-efficiently.

Cold milling machines are also frequently used to dig trenches for pipelaying or, when fitted with a deep milling unit and narrow cutting wheel, to mill slots. In short, the range of applications is immense.

W

hile the global crane market is growing steadily, the Asia Pacific market within that is growing much faster in comparison. The drivers are different, in a way. Globally, the market is driven by the ever-increasing oil and drilling industry. Given the race to control ever important oil exploration and drilling activities, both in the developed world as well as key developing economies, the demand for industrial cranes of various types has always been very healthy. This is supported by an expanding construction industry in every geography of the world. Industry trends suggest that, globally, the

crane market is of the size of $ 17-18 billion with more than 25,000 units of different crane types sold, but the growth numbers are a low single digit.

In contrast, developing economies such as China and India are presently the largest markets for cranes, providing a push for the Asia Pacific markets at least until the early 2020s. Thereafter, the markets in Latin America and Africa would also join this growth story for crane products. From 2017 onwards, China’s growth story has been steered by the OBOR (One Belt, One Road) initiative, whereby many road and infrastructure projects are being envisaged and implemented by Chinese construction companies. On the other hand, the story in India too is developing well, with the Government’s focus on infrastructure development in terms of roads, railways, ports, power and communication etc., along with the implementing of projects within manufacturing, defence, aerospace and other key industries.

Rising activities in the aforementioned industries means that cranes have wider applications in supporting those activities.

Commenting on the changes that are noticeable in the Indian market, Pradeep Sharma, president, Action Construction Equipment (ACE), opines, ‘The Indian market for crawler & telescopic cranes has traditionally been of pre-owned outdated European cranes. In the last few years, China has started offering cheaper alternatives to the European pre-owned cranes and, over time, some Indian companies like ACE felt the need to manufacture these cranes. That is how ACE started manufacturing and deploying entry-level crawler & truck cranes.”

Along with China, the Japanese too have started entering the Indian market with cost-effective quality crane applications. Yutaka Goto, MD & CEO, Kobelco Construction Equipment India, explains the need for newer cranes. He suggests,

CONSTRUCTION WEEK JUNE 2018 57

“With the shortening of the construction period and required savings in construction cost, reliability of the machine offers a direct benefit not only for rental companies, but also for end users and contractors. Kobelco is being chosen because of its perfectly inherited Japanese-standard quality and the advantage it offers by having a production base in India; along with its detailed direct service including optimal locations and skilled service staff.”

CURRENT LANDSCAPE In comparison to the global market or even the China market, the Indian marketplace is quite small in size. However, the potential of this market for the next 10-15 years is positively strong. The players participating in this area are also euphoric about these positive trends and are sensing strong demand drivers currently in operation. Tushar Mehendale, MD, ElectroMech, explains, “The entire Indian industry is seeing a turnaround from the malaise that affected it post 2011.

The momentum continues in the current year as well. Naturally this bodes well for the capital goods industry and for the materials handling industry in particular.”

He adds, “For industrial cranes, the market was shrinking year on year for the past 5-6 years, and now at least we are seeing a reversal of this trend on account of this. We are seeing demand arising across almost all the sectors of the industry. Be it infrastructure construction, steel, automobile, heavy engineering, etc., the investments have started happening again in India.”

Stressing on the renewed demand for new cranes, Sharma points out, “The 25T-40T telescopic cranes are now in demand primarily due to the requirement for new cranes. In steel yards, oil & gas and metro rail, the Government has made it mandatory to use cranes which are less than seven years old. These three industries have alone given a market of over 100 cranes per year in the past. Similarly, 25T/40T crawler cranes are

now used in piling applications. In metro rail and various road and bridge projects, ACE 75T crawler cranes, which are fully hydraulic contemporary machines, have totally replaced preowned mechanical and pneumatic cranes.”

Many heavy construction projects such as flyovers & bridges, power projects, metro projects and industrial projects have raised the demand for heavy-duty mobile cranes in the recent past. Subhajit Chandra, divisional head – mobile crane division, Liebherr India, states, “The demand for mobile cranes is expected to grow, especially in the case of higher tonnage cranes used in several application segments. We can see a lot of new players entering the market as many customers have started asking for newer cranes with longer service lives and lower energy consumption, as opposed to 7- to 10-year-old vintage cranes acquired by way of auctions and imports.”

CUSTOMER AWAKENING In a market that was extremely price-sensitive, and hence content with pre-owned and imported but used cranes, the customer’s preference for newly introduced crane products that are versatile in terms of their features has grown significantly.

This observation is reiterated by many prime vendors as well as their customers. Mehendale confesses, “One change that we are definitely seeing in the customer behaviour is putting an emphasis on premium products that are more reliable and have high levels of productivity. Buyers are willing to pay ‘extra’ for such products, upfront, as they are confident that such products are going to help them finish off their projects well within timelines at high levels of throughput. The days of ‘jugaad’ are slowly but surely getting numbered as technology

and productivity are being put at the forefront.”

Chandra agrees with this view and supplies, “This is quite encouraging for crane manufacturers, because apart from the obvious safety issues that these old cranes present, they are also one of the major hurdles to the introduction of new models.

Yet, the Indian crane industry is positive about quality products.”

When it comes to value-added features, Chandra proclaims, “Liebherr cranes have been equipped with VarioBase, which allows cranes to operate in congested areas by partially extending outriggers and utilising crane capacity in each direction as per the extension of each outrigger. Also, in few cranes, we have VarioBallast, wherein the increase of ballast radius is possible to use the full capacity of the crane and also to reduce tail radius in restricted sites.”

Placing an emphasis on changing requirements, Subhash Sethi, chairman, SPML Infra, informs, “SPML Infra is executing large and complex projects and we use high-load capacity, reliable and efficient cranes. Our vendors are reputed and well established and provide us with cranes of higher lifting capacity with long working radius and pick-and-carry capabilities.

These cranes are compact, easy to transport and assemble, with strong local service support. Any special feature depends upon the specific requirement of that particular project. For example, our pipeline project under Saurashtra Narmada Avtran Irrigation Yojana (SAUNI) in Gujarat requires very heavy load cranes to lift each of the 12m pipes, which have a weight of 15.6 metric tonnes, in order to place the pipe in the designated place with precision and safety.”

In addition, Sethi is of the opinion that Indian vendors are ahead in the game and make available all the latest features in their crane products. He claims, “India is moving along with the world for the kind of development required in offering both traditional and sophisticated technology in cranes and other

high-end construction machineries. We have almost all the modern construction machineries available in India; these are parallel to developed countries depending upon the utilisation and magnitude of the business and project.”

This brings up the question of safety. Mehendale stresses, “Safety is non-negotiable! The value of human life cannot ever be underestimated. All our cranes are equipped with several inbuilt systems that enhance workplace safety, whether the client demands it specifically or not.”

DELIVERING VALUE Of course, putting the customer first has become second nature. The most important activity when one sells premium products is to maintain an excellent dialogue with customers. Major vendors, who are successful with their premium segment, support this outlook. Sharma says, “Indian markets have recently realised that by paying a little extra for advanced & contemporary features in cranes, they are not only increasing the availability of their equipment, but also ensuring that its handling and operations become reliable, fast and safe.”

Mehendale suggests, “We have what we call a ‘solutions approach’ when we deal with our customers. This allows us to understand the client’s material handling problem in detail and present to the client a solution that solves the client’s problem, holistically. By following a consultative selling approach, we have been able to help reduce our client’s total project outlay and helped them gain a tremendous increase in productivity levels, along with a competitive edge.”

Chandra points out that, “We interact with our customer on a daily basis, and even help them with schematic solutions from time to time, depending on their different applications, even years after selling the machines. Liebherr’s own software LICCON work planner gives the customer an edge, helping them to plan their lifts.”

Goto of Kobelco says, “We think that it is our mission to re-

WE HAVE ALMOST ALL THE MODERN CONSTRUCTION MACHINERIES AVAILABLE IN INDIA. SUBHASH SETHI alise and grasp, in a timely manner, what is happening on the spot and what customers need. The latest cranes are commonly designed based on some modern safety standards such as EN13000 and general safety devices are equipped as standard. Among them, a telematics system is one of features attracting customers’ interest, nowadays. KCROSS (Kobelco Crane Remote Observation Satellite System) is a proprietary system that allows remote monitoring of the unit from the owner’s desktop. The system was designed to be as user friendly as possible, providing daily, weekly, and monthly reports that the owner can print.”

With regard to safety features, Chandra explains, “One of the major risks which is often overlooked by many users is the condition of the ground/ sub-soil on which the cranes are positioned. Another major area of concern is wind velocity. Customers are now concerned about safety features and they are gradually accepting the fact that, along with time, safety is also indirectly a key factor in saving money.”

On the whole, it is quite evident that the Indian crane industry is well poised to take its flight to glory.

ROOFING & WATERPROOFING

THE PROOF IS IN THE ROOF Roofing and waterproofing are important aspects of a home and must have the right materials and technology to make homes leakproof and weather-proof.

BY BINDU GOPAL RAO

A

s an alternative to asbestos roofing systems, screw down metal roof systems has been extensively used in the industrial and warehousing roofing in India. Trapezoidal roofing sheets are manufactured on state-of-the-art cold roll forming lines in transportable lengths as per the design. Sheets are fixed on to roof structure by specially designed self-tapping screws with aluminium washers, and all the longitudinal and side joints are sealed using silicon sealants and butyl tapes for ensuring a leak proof performance . In this system there is a penetration of roof surface and therefore high quality workmanship and roof maintenance are critical to having leak proof roof. PK Nagarajan, CEO, Tiger Steel Engineering (India), explains, “As

an advancement, we have introduced standing seam metal roof systems that completely eliminates penetration of roof surface.

Portable roll forming lines housed in a container are transported to the site along with required raw materials. Since the roofing sheets are produced at site, it can be in one single length from ridge to eaves, without worrying about the transportation constraints. This eliminates the longitudinal joints and avoids use of conventional sealing materials making the roof less vulnerable to leakages that arise due to deterioration caused to sealants.

Another interesting technological feature of this roof system is held by secret clips that are fixed on the steel structure, the roof panel side laps are rolled over the Clips and seamed in to 3600 double lock by with zinc coating of 180 motorised seaming

machine. The floating clips are designed for the thermal movements of roof sheets and double lock side laps along with secret clips provide secure structural performance against wind uplifts besides providing leak proof roofing system.”

This is surely one of the significant technological advancements suited to countries like India that experience heavy monsoons in most parts of the countries for about 3-4 months every year. Globally the non-asbestos corrugated roofing sheets are manufactured by using humid cure technology with high quantity cement which results in high density and heavier sheet weight. “HIL has developed breakthrough technology of non-asbestos corrugated roofing sheets by employing autoclave method with lesser quantity of cement which results in low density and light weight sheets. The product manufactured by this method has low drying shrinkage feature as compared to humid cure non-asbestos and asbestos fibre cement sheets and hence superior performance and durability is expected when stored,” says Dhirup Roy Choudhary, CEO & MD at HIL Limited (CK Birla Group).

MATERIAL ADVANTAGE In conventional non-asbestos roofing sheets, raw material used are cement, limestone, micro silica, and bentonite as binders and polyvinyl alcohol, polypropylene and wood pulp

are used as reinforcement. Popularly used roofing materials in metal roofing can be classified into colour and non-colour roof panels. On the upper end of the scale both colour and nonaluminum roofing panels are used in trapezoidal roof panels as well as standing seam panels. “Alumnium roofing panels are considered superior due its resistance to corrosion, better heat insulation properties, lighter in weight besides realisation of better resale value at the end of its life. Coating of zinc on metal is a traditional material used for a very long time in India.

Examples can be seen in the older industrial buildings as corru-

gated GI sheets. Earlier the sheets had zinc coating of 120GSM, and yield strength of 250MPA. In order to improve the performance, materials with zinc coating of 180GSM to 275GSM, yield strengths of 345MPA are now being used to provide superior structural performance and resistance to corrosion,” adds Nagarajan. Specialised coating of aluminium and zinc commonly called as galvalume have become popular in India as it combines the good corrosion resistance properties of aluminium and zinc giving users a viable alternative from the cost and performance perspective.

Likewise, COLORBOND steel is one of world’s most advanced and trusted pre-painted steel product for the building and construction industry that offers design flexibility and superior aesthetics to the overall structure; going beyond performance. Some of its variants are specially developed for the Industrial and coastal environments. ZINCALUME steel the substrate for COLORBOND steel ensures superior abil-

ity to resist corrosion up to four times longer than galvanised steel of equivalent coating thickness. COLORBOND steel is not simply painted, but has a paint system that delivers longer life and superior aesthetics. “The unique composition of the paint system consists of stable resins and inorganic pigments that do not break down easily even under severe UV radiation, thus preventing fading and chalking for longer. Also the coating technology is formulated to resist cracking and peeling during roll forming and usage. The colours too are developed in consultation with world’s leading colour consultants and building professionals. One of its technological breakthroughs has been THERMATECH technology that reflects sun’s heat to help roofs stay cooler thus reducing the inside temperature and overall energy consumption,” says Mahendra Pingle, deputy GM, market development, Tata BlueScope Steel.

NEW VISTAS The model of working with developers is primarily dependent on the nature of the project. “On one end of the spectrum, we only provide materials to a project based on the requirements raised by the developer, whereas on the on the other side we also engage with the builder in designing the waterproofing systems and suggest the most suitable waterproofing system as per the project requirement. In some cases, we also execute the installation, application and audit of the waterproofing system and provide end to end guarantee to the developer,” says Bahadur. Nakhul Jagannath, co-founder, Aqua Seal Waterproofing Solutions, adds, “Every developer has different needs and requirements. We at Aquaseal have detailed discussions around what the project needs, what is the risk taking capacity of the developer, post which we come

ROOFING & WATERPROOFING

up with alternative methods that the project could use. We also understand that there is no one fixed methodology that would suit a single project. We flex our initial plan based on the needs on an ongoing basis. In the past, we have also used multiple methods on a single project, thereby giving the end user a good solid waterproofed structure.”

Rajeev Jain, director, Nirmal, adds, “We have different coatings as per different projects. We use hydromax foundation waterproofing, drainage mat system, value insulation waterproofing, self-adhering sheet membrane, bentonite geo textile system, moisture remediation epoxy coatings, hybrid polyurethane coating and crystalline water proofing. These waterproofing are separate in terms of materials used and process used for them.”

GOING GREEN HIL developed non-asbestos roofing sheets branded Charminar Fortune as eco-friendly because no hazardous materials are used in the product, no waste is generated, byproducts of other industry like fly ash generated from thermal power plants, and cotton rag waste are consumed for manufacturing the product. About 80% of these raw materials are sourced from less than <150 kms, is 100% re-usable, and has no negative social impact. The main objective of a sustainable roofing

material is to reduce or completely avoid, depletion of critical resources like energy, water and raw materials; preventing environmental degradation and creating a built environment that is liveable, comfortable, safe, and productive. “THERMATECH technology reduces the amount of heat transferred inside the building, which results in better thermal performance and cooler comfort. In hot weather, COLORBOND steel can reduce peak roof temperature up to 60C. It can also reduce annual cooling energy consumption by up to 15% depending on the level of insulation, colour, building shape, orientation and function,” adds Pingle.

Tata BlueScope Steel is working towards creating sustainable and innovative building materials and products that will help reduce adverse impact on the environment. The thermal conductivity of the products is 0.167 W/mk against colour coated metal sheets 46w/mk hence the thermal insulation performance is expected to be superior than colour coated sheets. “Since the sheet weight is relatively low, the freight cost per sheet is also low. Lower sheet weight also helps in bringing down the overall structure cost compared to other alternatives. Thus it proves to be very beneficial on all accounts. The innovated products is light weight and high strength and meets performance requirement of national and international standards like IS 14871, EN 494 and ISO 9933,” says Choudhary.

Fixing a roof requires expertise and should be maintenance-free.

Roofing tiles come in myriad shapes and materials and users would best be adviced by architects.

(L-R) Nakhul Jagannath, co-founder, and Manish Bhavnani, proprietor, Aqua Seal Waterproofing Solutions.

PRODUCT MIX Likewise the market has several coatings for waterproofing. Pidilite Industries has the largest range of coatings in the Indian waterproofing industry from the Dr Fixit’s stable.

“We provide cementitious, acrylic, bituminous, polyuria and other hybrid coatings. These coatings have myriad applications based on the surfaces that they are applied to. As the range of the products in our portfolio is fairly wide, it would be difficult to comment on how distinct these products are; as one product used for a particular surface will not be relevant to a different surface,” says Dr Sanjay Bahadur, global CEO, construction chemical division, Pidilite Industries. The distinctiveness of the product is based on several parameters such as performance expectation, life, elongation and the overall durability and sustenance of the product at large.

Aquaseal Waterproofing uses different waterproofing coating systems such as acrylic, crystalline, polyurethane based systems. Each of these coating systems has its own unique properties. Acrylic coating systems are of two types: A two

70 CONSTRUCTION WEEK JUNE 2018

component acrylic coating system (2K) and crystalline coating systems. “A two component acrylic coating system (2K) is one which is mixed along with a polymer modified powder and is used predominantly in waterproofing of wet areas such as bathrooms, utility etc. These coatings are flexible in nature but cannot be left exposed to sunlight. On the other hand, a single component acrylic coating system (1K) possesses more or less the same flexibility and strength but can be left exposed to sunlight,” says Manish Bhavnani, proprietor, Aqua Seal Waterproofing Solutions. Crystalline coating systems are active systems i.e. their nature of developing insoluble crystals in a concrete structure is through the life of the concrete. This system acts as a catalyst in the concrete member to initiate the growth of crystals so as to stop the entry of water the minute the structure is exposed to water. This system gets stronger in the presence of water which is ideal to treat tricky leaks. Polyurethane based coating systems possess high flexibility and strength having elongation of about 250-1000%. These systems are ideal for large span of areas such as terraces, podiums, etc. They form a seamless coat without having any joints. Innovations in water proofing are also being seen in the market. In the last one year, Pidilite has introduced two revolutionary products in the raincoat range being “Raincoat Select” and “Raincoat Waterproofing Coat” which are specifically used for waterproofing exterior surfaces. “Along with us, specifically for roofs, we have introduced “Dr. Fixit Raahat” which is essentially a waterproofing + insulation solution, which can be used in slums and industrial buildings, as it acts as a technologically superior and longlasting product; when compared to aluminum sheets. These products have a strong proposition and we are certain that they will have a way forward; due to the benefits associated with them,” says Bahadur.
