Create a competitive advantage for businesses

Dong Chau production, trade and service company in Ho Chi Minh City, although it is affected by the Covid-19 pandemic like most construction companies, its construction work has not been interrupted . Even in the most stressful time of the pandemic, the company was still successful in securing jobs for workers and maintaining good sales throughout the year.

“We have overcome the pandemic by using prefabricated building materials in the construction of our projects. Importantly, during the pandemic, many companies urgently needed to build housing for workers to stay in factories. The building materials we used met the requirements of rapid construction progress and reasonable prices, so we received many construction contracts, ”said Mr. Le Tien Linh, director of Dong Chau Company.

Likewise, a representative of Tecco Real Estate Services Company – West Saigon Branch said that from design to building construction projects for partners, the company has always advised investors to choose new construction materials that are environmentally friendly. environment, such as bricks, aluminum frames, glass and decorative wall tiles. This has created a competitive advantage for the company in the market.

According to engineer Nguyen Thanh Nhan of HCMC University of Technology, new building materials and assembly building technology have gradually become popular, with many outstanding advantages over traditional ones.

“According to research, by using expanded polystyrene (EPS) panels, businesses can save at least 30% of the cost per square meter compared to traditional homes. With prefabricated houses, the workload is significantly reduced, which saves breakdowns, builds quickly, and lowers insulation costs and energy consumption. In addition, with precise dimensions, these materials are easy to construct and have less loss of material during construction. The construction time of prefabricated houses is only about half that of traditional houses and does not depend too much on weather and climatic factors as the modules were first processed and manufactured in the factory. The designs of construction projects using new building materials are more and more diverse and aesthetic, so they are more and more popular, ”said engineer Nguyen Thanh Nhan.

Architect Hoang Van Tin from the Association of Architects of HCMC added that with the technology of prefabricated houses using lightweight building materials, such as EPS panels, it has a simple design basis that can be built on n any terrain, from concrete to soft ground, even on water. Not to mention that the future expansion is quite simple, but the cost is not as high as the traditional houses. The prefabricated houses can be easily disassembled and moved to another location in a convenient way.

Still need a stronger push

The use of traditional building materials has had a negative impact on the environment, resulting in many consequences, such as loss of land, increased greenhouse gas emissions and other harmful gas emissions.

According to statistics, to make one billion clay bricks, about 1.5 million cubic meters of clay will be mined to a depth of about 2 meters, which is the equivalent of 75 hectares of farmland.

Over ten years ago, the Prime Minister issued Decision No. 567 / QD-TTg / 2010 on the development of unburnt building materials – a new form of environmentally friendly building materials as one of the resolutions for the protection of the environment.

Currently, Vietnam has over 1,600 factories producing unburnt building materials with many products such as concrete bricks (aggregate cement bricks), autoclaved / non-autoclaved aerated concrete bricks, aerated concrete blocks, hollow core concrete panels (acotec) and aerated autoclaves. concrete wall panels. The total design capacity of these facilities is approximately 10.2 billion standard blocks per year, which represents almost 30 percent of the total design production capacity of general building materials. With this volume, Vietnam annually saves about 7.5 million cubic meters of clay, or the equivalent of 375 hectares of land mined 2 meters deep, reduces the consumption of about 750,000 tons of coal and reduces gas emissions of about 2.85 million tonnes of carbon. dioxide.

However, compared to Vietnam’s total construction demand, this figure remains modest. According to many architects, the biggest difficulty in using green building materials is the habit of using iron and reinforced concrete in townhouses. Therefore, many people are still hesitant to use new products.

As for building material companies, their limits are in terms of technology, capital and experience in producing new environmentally friendly products. Therefore, to develop this field, companies must first establish links with each other for technology transfer, information exchange and healthy competition in the market. In the direction of the development of the building materials industry, the government and departments should have specific and preferential policies to encourage enterprises to produce environmentally friendly building materials.

There are no official statistics on the use of new building materials, but construction market records show that these materials are gradually gaining in popularity. Many architects from the Association of Architects of HCMC said that they have received many contracts to design construction works with new building materials.
