Requirement and Need for Making Net Zero or Carbon Less Buildings

The scale of the challenge ahead cannot be underestimated. Over the next 15 years, the world is likely to invest US$90 trillion in infrastructure, which is more than the entire current stock. The decisions made by each country, business or investor today will directly impact global climate and development goals. If done right, we can secure a growth path that will, by 2050, feed 9 billion people as well as providing clean electricity access to all and infrastructure services to the over 6 billion urban dwellers that keep cities running as engines of growth.

The world has already started on the journey towards a zero-carbon, climate-resilient future – testifying to the landmark global agreements of 2015 and 2016 on climate action and sustainable development, strongly supported by actions by national, state and city governments as well as businesses, investors, and civil society [1]. And momentum is growing: In early September, I joined business leaders, policymakers and investors at the Business and Climate Summit in New Delhi where we discussed how low-carbon strategies can be good for business and good for development. But whether we shift to the right path in time to avoid the worst impacts of a changing climate depends on action on three fronts: clear and credible policy that can unlock capital at scale and unleash an era of low-carbon innovation.

International co-operation will be critical as a lever to strengthen and more effectively distribute the flow of new ideas and technical capacity, mobilise and scale up finance and help overcome concerns about loss of competitiveness and increase the scale of markets. By working together, countries, businesses, cities and others can move faster and achieve greater gains.

First, on the policy level, governments play a key role in delivering the right enabling conditions. For instance, collectively, they could signal decisively that high-carbon, highly polluting development comes at a significant cost. This could include, for example, the introduction of meaningful carbon prices and reform of fossil fuel subsidies which are estimated to have amounted to US$325 billion in 2015 alone.

Today, more than 42 countries and 25 sub-national regions have, or are actively planning, a price on carbon; and an estimated 50 countries have started or accelerated fossil fuel subsidy reform. But the carbon prices and coverage of emissions are too low in almost all schemes. A new OECD report on Investing in Climate, Investing in Growth, shows how the use of carbon pricing and other efficient climate policies, together with structural reforms, can enhance both short-term and long-term growth. Ramping up efforts, such as those led by the Carbon Pricing Leadership Coalition, will be key to progressing the May 2016 announcement of G7 leaders to eliminate inefficient fossil fuel subsidies by no later than 2025.

 

Second, we need to mobilise and align finances so that the right kinds of investments are made. This includes utilising public finance in ways that can leverage private finance. Multilateral development banks play a key role in this, including mitigating risk, providing concessional finance and bringing private capital to the table, especially in less developed economies.

Again, there are promising signs of momentum towards low-carbon investment: as of October 2017, over 400 investors with US$25 trillion in assets under management joined the Investor Platform for Climate Actions. The Norwegian Sovereign Wealth Fund, the world’s largest at US$1 trillion, has divested from over 50 coal-related companies, in line with ethical guidelines it adopted in 2016. Over 100 businesses, including Unilever, Barclays and HSBC, have committed to implement the recommendations of the G20 commissioned Task Force on Climate-related Financial Disclosure, translating into disclosing climate information as part of their mainstream financial statements. Countries are also aligning their policies with these efforts: France, for example, has mandatory corporate disclosure of climate information, which includes financial risks from climate impacts and carbon reporting across the supply chain. The Chinese central bank has proposed mandatory climate disclosure as part of a series of other reforms to help green its financial system.

Other welcome signs of momentum include initiatives like Partnering for Green Growth and the Global Goals 2030 (P4G), a green growth engine that creates space for partnerships of businesses, national and city leaders, financiers and community advocates to join forces in the development and deployment of targeted opportunities that can accelerate the delivery of sustainable development. They are offering practical solutions, and they also carry an important message: not only is the transition to a low-carbon economy possible, but it can be good for business’ bottom line.

Finally, the global community needs to invest in innovation. Energy-sector public R&D is less than half of what it was in the late 1970s in real terms, and still often goes to fossil fuel exploration and production. Yet, the transformative potential of what can be achieved is staggering. BNEF, for instance, forecasts such a rapid expansion for electric vehicles along with changing patterns around car sharing or pooling over the coming years that there may be an ‘iPhone moment’ of innovative disruption.

At its core, our efforts to secure a safe and sustainable growth path depend on coalitions of governments, investors, businesses and civil society working together to accelerate this transition: the opportunities are there, we just need to seize them.

Need for Bricks modification practice to improve the quality of Construction

econaur.com

Following China, India is the second largest manufacturer of bricks across the globe. No wonder, this very building material holds so much of importance in the Indian architecture. India alone produces over 10 percent of the bricks which are globally produced and has about 1,40,000 brick-making enterprises, who account for 250 billion brick masonry units (Source). This industry also employs around 15 million workers and consumes annually over 35 million tons of coal. Today there are many other options available to choose from when it comes to building materials, but bricks have always been one obvious choice. This is industry is surely growing as the demand for Bricks never declines due to the fast-economic growth, urbanization, and prosperity. This blog aims to explain how this legendary building material – Bricks, are made. Yes, let’s simplify it for you – The Brick Making Process In India.

Demystified – Brick Making Process In India

The brick making process typically consists of the following steps.

econaur.com

  1. Preparation Of Raw Materials

In this first stage, the soil is mined in steps and then laid on a leveled ground where it is cleaned of all sorts of impurities (like vegetation matter, stones, pebbles etc). Once the material is clear from all impurities it is left exposed to weather for few months, this process is known as weathering. After this, the soil is mixed with other material to prepare good brick earth. Post raw materials are mixed, it is tempered in a pug mill by thoroughly breaking, watering and kneading it.

  1. Shaping Or Moulding

Initially, moulds used for shaping bricks were made of wood, and the makers used sand to ensure the bricks didn’t stick to the moulds. But today there are many other options available for this process. Depending on the quality of the end product, bricks are moulded in many different ways. The most common methods for shaping or moulding bricks are hand moulding and machine moulding.

  • Hand Moulding – The tempered is clay injected into a mould in such manner that it fills in all the corners. Extra clay is removed using a frame with wire or with a wooden strike. Once proper shape is ready, the mould is lifted and what remains on the ground is raw brick.
  • Machine Moulding – This method is used where large numbers of bricks are manufactured. Essentially there are two different types of machines used for moulding bricks:
  • Plastic Clay Machines – Here the clay is in a plastic state and it is forced into rectangular openings of a size which is equal to the length and breadth of the bricks. Further, these are cut into strips of a similar width of the bricks with the help of wires in frames.
  • Dry Clay Machines– Here dry clay is condensed to powder which is filled into moulds by the help of machines. These are then exposed to high pressure to form hard and well-shaped bricks.

  1. Drying

Drying is one of the most important steps in the brick making process. Thinking why are bricks dried? The main reason is to avoid cracks, it is important to understand that damp bricks if taken directly for burning result in cracking. Drying bricks ensure that inadequate moisture is removed before the burning process. Also drying increases the overall strength of raw bricks making them ready to be stacked on greater heights in the kiln for the burning process without damaging it.

Usually, drying is done by simply placing the bricks in sheds which have open sides, this ensures free air circulation and protection from extreme weather conditions. The drying process of bricks varies from 7 to 14 days.

  1. Firing or Burning

After drying, the bricks are fired to high temperatures in furnaces. Burning is another very important step in the brick making process. Bricks in India are burnt by two distinct methods listed below:

  • Pazawah Or Clamp Burning
  • Bhatta Or Kiln Burning

Talking about clamps now, this is a field kiln which is built from the green bricks which would be fired. Clamps vary in size and shape and are carefully oriented with respect to the direction of the wind. Once a clamp constructed and laid out, it needs to be insulated.

The process of firing takes place in several steps. The first step is pre-heating or water-smoking which removes the leftover water from the drying process. After this process comes the stage of firing, here clay bricks vitrify through a chemical process. Temperatures in the clamp must remain constant during this stage to complete vitrification. Cooling stage is the final one, here the temperature needs to be slow and steady.

Brick Production In India

The major brick producing states in India are Uttar Pradesh, Haryana, and Punjab. These states together account for around 65 % of the entire production in the country.

The scale and production of bricks in India varies across India mainly due to the availability of fuel and soil. Even today, traditional techniques are used to produce bricks, and the process involves the use of inefficient methods and manual labor. The manufacturing process of bricks is dependent on seasons as the process of drying and firing are still carried out under open air.

The brick kilns are located around main cities and towns, these clusters have an annual production capacity of over two to ten million bricks. Because of the seasonal dependencies, these kilns operate only for six to eight months in a year.  During the monsoon season, the production process literally comes to a virtual halt. In the Northern mountain regions, (like Jammu, Srinagar, and Dehradun) brick production is very limited and low.

Conclusion

The building construction in India is expected to grow at a rate of 6.6 percent from 2005 – 2030. Over the coming years, the demand for building materials will also rise exponentially. Also, in the past two decades, many alternatives like concrete blocks, FaL-G blocks (fly ash-lime-gypsum) and AAC (autoclaved aerated concrete) have come up. While these alternatives might cost you less, think about what it would give back to the environment. Think Green and Build Green!

Construction Manager : An Helpful Hand in Managing a Quality Construction

The construction industry is in a constant state of alteration, and those who want to be in the know about what is happening in every corner of the industry need to be entangled in to the right resources. Just ceasing us from being faded of the inscrutable fact of right resource, the first and foremost brooding is concerned to Construction manager. Construction manager is the backbone of all the innovations would it be Burj Khalifa or great wall of China, the crucial role for their innovative design is unique approach of its construction manager.

Construction managers are responsible for setting and keeping schedules, monitoring finances, and making certain that everybody is doing what they should, every day. They help ensure that the workplace is free of safety hazards and deal with the various working relationships that exist on a job site. Construction managers oversee and lead a range of building projects from induction to perish.

Construction Manager vs. General Contractor
While the terms “construction manager” and “general contractor” are often used interchangeably, there are distinct differences between them. Typically, construction managers are involved in a given project from initiation to perish. They assist clients with initial planning, along with the selection of the project’s general contractor and architect. In some cases, however, construction managers do serve in a separate capacity as the general contractor.

Responsibilities of a Construction Manager
There are certain sort of works that are performed by construction managers. These include:

Quality management – Construction projects quite often involve a number of contractors and subcontractors. One of the most important jobs of the construction manager is making certain everyone is doing quality work and not cutting any corners along the way. Quality management is enhancing day by day. Nowadays it is more prefferd to have a manager who has done certification courses related to quality control like Six sigma. Six Sigma is a statistical tool that patronizes us in questing out the root causes of failure of any task and assist us in smooth and easy completion of task.

Cost management – A good construction manager is constantly on top of costs and makes the necessary adjustments when unexpected complications or issues arise. He works on the aim of high customer satisfaction with high profit to the company.
Safety management. Construction managers need to be able to identify and eliminate possible safety hazards for the good of everyone on the job site.

Contract administration – It is the job of the construction manager to ensure that every provision of the contract is being met and that all parties involved are happy. Beyond everything else, construction managers need to keep all parties involved well informed throughout the whole project. It includes the client, the architect, and any contractor or subcontractor involved. If issues arrive, the manager must be in the position to deal with them immediately. So if you are opting to be an innovative construction manager one need to be more specific and knowledgeable towards the work because it not merely checking only the smooth functioning of work one should be aware of statistical tools, mathematics, construction software and architecture but where there is will there is way. So keep on commanding on all basic and technical terms of construction one can easily be an excellent construction manager.

Parameters which decide salary of construction manager :
1. Experience :- In almost any profession, the more experience you have, the more you can realistically expect to earn. If you have more than 10 years’ experience in construction and have worked your way up the ranks to your present position, you could find yourself being offered a better salary package than someone who is fresh out of college with minimal real-world experience.
2. Education :- Experience can get you far when it comes to getting a good pay rate, but experience plus education can boost you into that median range much more quickly.
Do you have a degree in construction management? Numerous online programs can get you there while you continue to work and build your reputation in the industry. Once you earn your diploma, you can reasonably expect to be offered a better starting salary than someone without a degree, and, really, most well-paying management positions will require it anyway.
3. Number of Subordinates :- The number of people you will be managing also has a direct effect on what you can expect to be offered. If you are applying to a small startup, you will be on the low end of the pay scale based on the company’s annual revenues and a host of other factors.

A larger, more established company with more employees will proceed you a better salary every time, but it will also expect and demand a certain level of education, experience, and proven ability to handle managing large numbers of subordinates effectively.
Econaur team is always in assistance to make excellent construction manager.
