Precast Concrete & Equipment

Material advantage

 

 

National initiatives aimed at prioritising housebuilding will boost demand for precast concrete products and equipment 

 

 

With cities like Mumbai, Delhi, Bengaluru, Chennai, Kolkata, Ahmedabad and Pune out growing their former limits and increased demand for constructing new structures – residential and commercial like hotels, offices, malls and SEZs – the challenges of building them are huge particularly in the light of requirement of delivery of enormous volumes.  Now with the government focusing on fast tracking infrastructure development, the concrete and concrete equipment industry is capturing the attention of the country’s top policy makers.

 

 

Growing requirement for fast construction and the need to minimise time and labour involvement has today put precast concrete products and technologies in the limelight. As the country gears to build new infrastructure like roads and highways, bridges, metros, ports and airports, railways and power, and the skyline of cities like Mumbai, Delhi, Bengaluru, Chennai, Kolkata, Ahmedabad and Pune changes, the use of precast concrete is expected to steadily increase and will be considered as the most viable option to speed up construction process.

 

 

Precast concrete has already gained wide acceptance in developed markets but is yet to establish its stronghold in India. According to industry experts the Indian construction industry is worth about $500 million and only 2 per cent of its share is occupied by precast technology as against conventional methods. The leading players in precast concrete manufacturing include Elematic India, Magicrete, Vollert , Spancrete, Webau India, Precast India, Bianchi Casseforme India and Putzmeister.

 

 

 

REALTY BOOST 

 

Precast concrete concrete find applications over various segments of real estate. In the case of high end condominiums they reduce the need for load bearing walls and thus contribute to the interior layout of the apartment becoming more flexible and attractive from the point of sale. Usage of decorative precast walls or spandrels on the exterior makes the building more attractive in terms of elevation treatment.  Further in the case of structures like hotels and hospitals which require large column free space – to accommodate restaurants, dining rooms, operation theatres and waiting halls – precast portal frames at the ground floor to support the load bearing walls of the larger super structure could be employed effectively. Precast pre-stressed hollow-core slab units offer the best solution for commercial buildings which are largely column beam framed structures requiring large column free areas with floors large span load carrying capacity.

 

 

Ergo, with precast concrete at the heart of every real estate construction project India now represents an enormous opportunity for real estate developers and constructors. It is increasingly becoming a practical option for its cost effectiveness, environment friendliness – it reduces energy consumption and subtracts from the waste and dust on site – and in ensuring longevity of the structures where such technology is employed. Studies have shown that precast concrete products can provide a service life in excess of 100 years. Further using precast hugely also subtracts on the cost of construction labour and maintenance, ensures seismic resistance and for the developer ensures a quick financial turnover.

 

 

Firms like Supretech Ltd, the Amrapali Group, Sobha Developers, the Raheja Group and Tata Housing have earned a reputation for using precast products in their projects – the product reportedly saves up to 64 per cent of the time involved in the construction process. For instance, while a normal brick and mortar method involves one year for project completion, the same initiative can be completed using precast concreting technology within four months. Realising the tremendous material advantage the Bengaluru based Sobha has developed in house delivery capacity and a large manufacturing capability to support precast, concrete products, metal and glazing and interiors. The company is the first developer in India to have set up a precast plant to cater to its new project — Sobha Dream Acres and 7000 units of 650 sq. ft. and 1200 sq. ft. which will be developed on precast technology.

 

 

 

BUSINESS OPPORTUNITY

 

The current global trends suggest rising demand for precast technology across the world. Elematic, a world-leading manufacturer of precast concrete plants and production lines, will introduce an innovative crushing mixer to its Acotec non-load bearing precast partition wall production line at Bauma 2016 in April. It will also launch a new software product at Bauma 2016 to cement their strong know-how in precast production automation. The manufacturing execution system for precast floors will offer a complete solution to enhance the efficiency of hollow core slab production. Elematic’s other remarkable software products include ELiPLAN, an enterprise resource planning system specifically designed for precast factories. Eyeing future prospects and the increasing requirement for smart construction in the country, Elematic India plans to invest in a new manufacturing plant at Alwar in Rajasthan.

 

 

Spancrete, a leading US based full service precast company – which engineers, produces, transports and installs all precast products from structural to architectural to floor and roof elements and bridges and even infrastructure precast civil works – has sold a plant to the MAAD Group of Companies. The Vasai plant is part of a huge project intended to produce 2 million sq ft of hollow core slabs.  The products will be targeted for affordable housing programs and to meet requirements in diverse sectors like sports complexes, educational facilities and industrial centres.

 

 

Terence W Dittrich, Global Sales Director, Spancrete Global Services says, “We have been seeing in the last 2-3 years an improving awareness among the project managers, engineers, architects consultants, developers, contractors, builders, etc, especially in understanding the speed of construction by using precast. We see them being challenged by labour availability, unsafe on-site working conditions, and by quality control – so all of that is driving them towards precast.” 

 

 

 

MARKET PROSPECTS

 

It is not difficult therefore to see why the mood in the market is so positive. The total market for concrete precast products is likely to continue on its relatively strong path of growth in the short to medium term. In the medium-term, annual growth rates of 7-11 per cent are forecast to 2019. The precast concrete products market is affected by global demand, supply and pricing issues which remain volatile as well.  The current trends in the greater construction sector and a broadly positive outlook in the underlying economy are likely to stimulate further growth in the market. Initiatives aimed at prioritising housebuilding will boost demand, at least in the short to medium term.

 

 

Affordable mass housing is a segment which opens up immense prospects for precast concrete technology.  According to the 12th Plan Working Group of India on Financing Urban Infrastructure, the urban housing shortage in the country is estimated to be about 29 million units. The study indicates that with the urban population expected to surge to 600 million the demand for affordable housing is likely to rise to 38 million household units by 2030. Pre-cast concrete is the answer to meet all these requirements and is expected to bring the next big revolution in the Indian construction domain. The technology has also emerged as a convenient construction solution for Indian public sector units. For instance, the Delhi Development Authority recently constructed an affordable housing project of 18,000 precast units within 2 years. Encouraged by the quick results the body has now commissioning another project of 27,000 houses using precast technology. Admittedly precast concrete holds great construction potential.

 

 

Chander Dutta, MD, Elematic India Pvt Ltd is led to say, “If the government wants to stick to its vision of providing ‘Housing for All’ by 2020 the precast industry needs to be effectively encouraged.
