EDITOR'S NOTE

CAN INDIA BITE INTO THE $ 680-BILLION EPC MARKET?The Government has recognised

that the economy is suffering and needs a strong booster dose – placebos just won’t work. Today, all the ministers are brainstorming over revitalising the economy. For our part, CONSTRUCTION WORLD, along with Foundation of Infrastructure Research Studies Training (FIRST), took up the challenge and presented Union Minister of Commerce & Industry Suresh Prabhu with solutions to inject adrenaline into the economy. The overall intent is evident: bring in foreign exchange, enhance employment, contribute taxes and plan for long-term positive development for the country.

One of our solutions is to strategise to attract the ‘engineering research and design’ industry to India. This $ 680-billion industry is projected to move $ 170 billion – 25 per cent of total revenues – to Asia. Companies like Bechtel, AmecFoster & Wheeler, Black & Veatch and others are based in India, employing thousands of engineers creating engineering designs for complex multibillion infrastructure projects around the globe. This brings in foreign exchange, tax payments and employment. In fact, India has a talent pool of nearly 500,000 engineers graduating every year; such companies can help boost their skill sets and hone them as worthy assets for the country’s future technical talent pool. The stakes are high—$ 170 billion as mentioned

above – and India should stake a claim. Back home, we have such skill sets in public-sector companies like Engineers India, RITES, IRCON, MECON, Engineering Projects, WAPCOS, and so on. Going forward, our EPC companies can create SPVs with such projects to forge future alliances as the home infrastructure market opens up to these global giants from the design and engineering space.

Our recent exercise in analysing India’s Fastest Growing Construction Companies has thrown up new names into the orbit that have grown geometrically over the past three years. These have shot to challenge the

erstwhile fastest growing companies, indicating that new money has found its way to supporting companies that do not carry ‘legacy baggage’. Our jury comprising India’s top three rating companies debated the merits of excluding companies on grounds of questionable governance practices; therefore, some companies had to miss their spot of glory. This issue, bearing an element of surprise, we also present the nominees of this exercise. In our view, to be nominated is an important milestone in itself.

Early this year, CONSTRUCTION WORLD launched a new logo that

intended to depict the increase in mechanisation, scale of infrastructure projects, project management expertise and adoption of technology. After scouring over the responses and suggestions received, we have conceded that our old logo stands tall with its leadership image well-entrenched in the minds of our readers and followers! Therefore, we have decided to bring it back amid the festivities of the month. On behalf of the entire team, I wish you all Happy Diwali and a prosperous new year!

Between the environment exterior to a building and the interior environment lies the façade.

“The first and most important function of the façade is to act as a filter between the inside and outside environment,” says Manit Rastogi, Founder Partner, Morphogenesis. “The façade modulates daylight, heat gain, glare and solar control. Also, it is expected to fulfil structural performance expectations, in terms of wind load, structural integrity, etc.”

Performance over aestheticsPerformance is the buzzword in

façades nowadays. “Functionality, utility and longevity are our clients’ top priority although they want a material that is simultaneously strong on aesthetics,” says Ankit Mohata, Managing Director, Straton Group.

“From a functional point of view, owing to poor civil construction, cladding is becoming a necessity. Also, in terms of energy-efficient façades, cladding is here to stay,” says Dr Prashanth Reddy, Managing Director, FunderMax India (Read his full interview on Pg 50).

Typically, the energy load of a façade should not exceed 1 W per sq ft, reckons Rastogi. However, he opines that most façades are very inefficient, presenting a load of 4-5 W per sq ft.

Façade performance is critical in a hot and dry climate or composite climate. While performance also matters in a hot and humid climate like Kolkata, the intensity there decreases slightly, says Rastogi, decreasing further in a city with a more temperate climate like Bengaluru. Having said that, climate change has increased the overall temperatures that the latter city experiences.

walls with high water-absorptive claddings.


COVER STORY

To enhance the performance of a façade, control the window-to-wall ratio and use high-performance glass, suggests Rastogi. Essentially, think of optimising the entire building envelope, not just the façade. After all, the elevation or the façade is not separate to a building but an integral building element.

“Façade performance depends on the kind of building you make and the context you are designing in,” says Sanjay Puri, Founder, Sanjay Puri Architects. “A façade is not designed in isolation and stuck onto the building; it is integrated with the building.” Puri cites an

climate, say in Rajasthan, should be north-oriented with hardly any sun coming in from the south, to reduce heat gain by 30 per cent. Accordingly the north side should have larger openings compared to the south side.

“Max Exterior panel from FunderMax – used in conjunction with rear ventilated façade – is eco-friendly and can help achieve the necessary energy-efficient rating,” says Dr Reddy. “The manner in which the panels are installed and the way they perform result in thermal efficiency along with product characteristic.”

High-pressure laminates, wood-polymer composite and other cladding fitted with rear ventilation slightly lower the interior temperature

Façade modulates daylight, heat gain, glare and solar control; it is expected to ful l structural performance expectations.

Energy-ef cient glass is a suitable front for green buildings whose performance must be addressed through their façade.

“High pressure laminates as rear ventilated facade offers an excellent option for

facades.”

and can thereby reduce the energy load of a building, says Mohata. “Essentially, the ventilation ensures air circulation and insulation. While some of these façades can cost up to two-and-a half times the cost of ordinary panels, discerning developers are increasingly favouring a higher capex against lower opex in the long run.”

However, aesthetics as applied to a façade are about more than meeting the occupants’ expectations. “A building should ideally blend in with the culture of the place; this goes for the façade as well,” he adds.

“A façade is not only important from the perspective of performance of the material, a deep understanding of the cultural heritage of an area is important to design buildings that look familiar, to enmesh the cultural connect of people, place and climate,” says Sharukh Mistry, Founder Partner, Mistry Architects. “Some façades you see today in smaller towns

the culture and lifestyles of people.”

Material accountabilityAll the material components of

the façade are answerable for the long term, which means the materials must add rather than take away from the life of the

Easy-to-maintain Façades “Natural materials like granite are more expensive compared to regular

brick walls as well as challenging to use for tall structures. Glass and aluminium are cost-effective and easier to maintain; they require regular cleaning but are durable,” says Kishore Bhatija, Managing Director, K Raheja Corp.

“FunderMax has always laid emphasis on sustainability and all our products are maintenance-free. Contrary to aluminium panels and glass that require a high element of cleaning and maintenance, our panels can be more or less classified as zero-maintenance,” says Dr Prashanth Reddy, Managing Director, FunderMax India.

“Windows need to be openable; this enhances safety.”

- Sanjay Puri, Founder, Sanjay Puri Architects

Given India’s hot climate, there is a need to balance the use of glass with other materials.

Culturally aesthetic façades A façade can make or break

the look of a building, and hence attract or put off potential clients and tenants. “Aesthetics are important because finally people live in the space and expect it to look good,” says Harshavardhan Neotia, Chairman, Ambuja Neotia Group.

journey that has brought quite a few learnings amid several challenges faced. A major one has been change management – how do we adopt ourselves to a given situation? That said, we have evolved into becoming a profitable company and an established architecturally preferred brand.

With a total estimated size of over 80 million sq m per annum, how do you see the façade industry

evolving in India? The industry is growing by the day. There is certainly demand for cladding; it can work both aesthetically and functionally. While in the past, it has largely been driven by aesthetics, the

functional aspect is taking over now.

Amid this evolution, what is the company’s current market share, vision and set strategies?

At present, the market share is big with huge potential for growth but nothing is being offered on the platter. That said, our approach has always been driven by the focus to find and build our market and realise our aim. We are present in 44 cities working with key architects and focused segments, driven more on specifications. To be a complete solution provider, it is extremely important to utilise your resources optimally and stay focused.

What keeps the company ahead of its competitors in terms of services offered?

This largely unorganised market is slowly moving towards getting organised. Moreover, government regulations such as GST are helping the organised sector gain

such as ours have made a difference to the industry by bringing in world-class products. Additionally, to effectively communicate our offerings, we are trying to educate the industry on the advantages of using the products and the inherent value benefits. Further, a large share of the unorganised market involves the unskilled and untrained labour force. We educate and train them, and have established a trained and skilled partner network across the country for installation.



How has the company’s business volume growth been; what has been driving this growth?

We have always clocked a profitable, double-digit growth. Our positioning has been extremely critical for our success. Going by our tagline, ‘for people who create’, we have been trying to emphasise upon the need to bring in a certain character to façades; there should be an emotional connect. All our awareness and education campaigns are geared around this.

FunderMax has been a leader in energy-ef cient façade materials .

Max Exterior panel from FunderMax – used in conjunction with rear ventilated façade – is eco-friendly and can help achieve the necessary energy-efficient rating. The wood – raw material for our product – comes from renewable sources that are PEFC and FSC-certified, further contributing to a sustainable environment. Product performance using rear ventilated façade concept results in energy-efficiency.

Considering the increasing demand for façade and cladding, and government initiatives such as

the Asia Pacific as well. However, at this point, we do not have a fixed timeline for the factory set-up.

What is the emphasis laid on R&D, especially for the Indian market?

R&D is more of a global approach and we do not have

to be a complete solution provider. Although the panels come from Austria, the entire implementation system is being driven from the

conditions, its project and design requirements and the local laws of the land. So R&D in this direction is still happening. Thus, except for the

fact that the panels are not made in

That said, a sizeable investment goes into our R&D activities, because we believe that until you invest in future innovation, sustainability will remain a challenge.

Tell us about your channel expansion strategies in the market.

We have been touching a scale of an average 1,000 projects every year, and over the past 10 years, we have completed close to 10,000 projects. This growth would not have been possible without the valuable contribution from our business partners, and the credit goes to them, who have been able to scale up their respective business to handle this exponential growth. They carry out most of the pre-sale and post-sale services to our customers and almost 100 per cent of our product installation is handled by them. Our endeavour is to form sustainable business partnerships with profitable growth, and we are constantly working towards the same.

Going forward, can we expect any announcements?

There is a lot happening on the product development front. Bringing in any new collection requires the effort of four to six years by a team of 20 designers working round the clock. But we try not to overdo it by launching too many products in a market.

Among modern materials, aluminium is the best and most popular façade material, says Rajeev Antony, Managing Director, Schueco India. “Stone or ACP cladding are other materials. Steel is comparatively heavy and typically used as a structural material as an alternative to concrete, when it becomes the substructure for the façade.”

“The façade design or material must meet the aesthetic requirement of the architect, and the aesthetic appeal of the owner,” says Navin Keswani, Managing Director, Aluplex India.

“Aluminium is the preferred raw material for the profile and structural support of the façade system; the façade system duly designed and engineered correctly is then leak-proof, waterproof and resistant to high wind loads and adverse weather conditions. Glass is the most popular infill material for being available in a variety of colours, and permutations and combinations with respect to solar

“Solid metallic sheet cladding is replacing ACP cladding in various applications for being maintenance-free, more fire-resistant and creating an impeccable external wall,” says Ravindra Shekokar, General Manager-Operations, TeamFacades. “Also, architectural metal mesh is becoming popular for being suitable for a wide range of designs (perforations), especially where ventilation and aesthetics are critical.”

cladding, sunscreen and sunshades are being used in extreme sunlight conditions,” says Kapil Chikodi, Head-Business Development, Glass Wall Systems. “We are also using metal cladding.”

Advantage: Rear-ventilated Façade“Most façades in India are closed systems,” says Dr Prashanth Reddy,

To the contrary, FunderMax provides a rain screen façade system that improves the functional performance of the façade with respect to heat reduction, noise reduction, better weather protection and improved thermal efficiency through effective design, making it a sustainable building.”

“Rear-ventilated façade systems are good for walls with high water-absorptive claddings, such as bricks, blocks and renders, so they are suitable for older buildings,” adds Kapil Chikodi, Head-Business Development, Glass Wall Systems.

brings in an unwanted amount of heat and light,” observes Dr Reddy. “Also, if you have a closed façade system with energy devices like air-conditioners working inside, it results in energy loss.” He advocates “working with a smart design element where we can talk about double-skin façades, we could bring in the necessary light but not the heat and prevent energy loss from the inside to outside.”

Double screens Double-screen façades have

become popular overseas, says

Antony. The two skins or screens serve the important function of providing occupants with higher building performance (thermal, acoustics and ventilation). Also, the outer skin provides design flexibility to architects for better aesthetics.

“With a dual-screen façade, depending on the weather condition, you can disengage the openable to allow natural ventilation between the two skins, thereby creating a thermal bridge which creates an acceptable indoor temperature during summer and winter” explains Antony.

“Between the two screens, service levels and ducts can be created for the sake of convenience, and HVAC equipment placed.”

The cost factorFaçade materials vary significantly

in cost and performance. Glass façades are more

expensive than aluminium façades in terms of the material cost, system profiles and installation,

says Khanna. “But this higher capex converts into lower opex and safety, considering fire-resistant glass can resist fire up to 120 minutes.”

“A metal façade can be 20-30 per cent more expensive than glass and aluminium façades owing to higher cost of solid metals,” says Shekokar.

A positive is that the industry is gradually evolving towards judging materials for their performance.

“The industry is slowly moving from being extremely price-sensitive to a value and benefits-driven approach influenced by growing awareness and global trends, which is a positive development indeed,” sums up Dr Reddy. “Also, the industry is bracing up for the challenges of complex façade design and so far has been able to handle it well.

Façade safety

Tower went up in flames killing 80 residents. About a year prior to this disaster, the building had been given a new look, a façade comprising two layers of aluminium sandwiching a combustible core of polyethylene, a highly flammable material. When a malfunctioning fridge triggered a fire, this very highly flammable material is believed to have helped it to spread rapidly. Questions have arisen in

flammable cladding in façades. Does the material used in the façade impact building safety so majorly? What is the role of installation in ensuring the safety of a façade and, hence, of the building?

Citing the Grenfell Tower fire as well as a couple of residential towers in Dubai where fires have recently broken out, Mohata emphasises on the need for cladding material with fire retardancy and flammability-spread specifications matching ASTM or - CHARU BAHRI

spreads mainly through the exterior cladding material, not through the RCC; so, gauge a material based on the flammability spread, toxicity report, smoke density and other parameters.”

“Fire retarding cladding is

in a façade is as potentially hazardous as poor installation from the stability point of view,”
