Dubai Municipality has entered the Guinness Book of World Records by constructing the world's largest 3D printing structure in Warsan, a two-story, 9.5-meter-high, 640-square-meter building that has been ranked as the world's largest two-story printed building.
The completion of the building is based on the directives of HH Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to build 25% of buildings in the Emirate of Dubai with 3D printing technology by 2030.
Daoud Al Hajri, Director General of Dubai Municipality, told reporters yesterday that the cost of the building is 800 thousand dirhams, while the traditional construction method would cost about two and a half million dirhams, which means that building with 3D printing reduces the cost by up to 60% .
He added that the building took only three months to construct, including the construction and finishing works, while it would take at least a year for the traditional construction system, stressing that the municipality has taken into account all safety standards in construction, in addition to the criteria for sustainability and green buildings. Al-Hajri said that the project is a radical turning point in the construction sector at the local and regional levels, and depends on the strategy of innovation in printing techniques in construction, which in turn will increase the pace and speed of implementation and completion of buildings in record time, and reduce construction costs, and contribute to the development of solutions to the challenges of demographics by reducing The number of construction labor, which will also support the Emirate's trends in the field of sustainability, using local materials, and reduce construction waste, where printing is done electronically according to engineering plans directly without human intervention.
He pointed out that the national cadre and the Municipality team were in the picture during this achievement, as the consultative body that supervised the completion of the project in all stages, is the 3D printing team of the Department of Building Permits, and no external consultant was hired, pointing out that the municipality prepared all Equipment to deal with modern technology in the field of construction, which achieves Dubai's 3D printing strategy, with the aim of making Dubai a global capital for this technology.
Al-Hajri said that the design and implementation of the two-storey building includes a number of spaces, which can be used as rooms or offices of different sizes, by printing walls directly from the printer, unlike the traditional method of construction, which was based on the work of wooden formwork, reinforcement and casting. Concrete and brick construction, as well as the design of the building with different curves and shapes, shows the possibility of triple printing in the building in a variety of designs.
Various tests and tests were conducted on the mixes of the materials used in printing, to ensure that they fit the smoothness and pumping of the printer, as well as to ensure that they meet the requirements of quality, consistency and strength required to withstand the construction, and the municipality made sure that the materials used in the mix is available in the country, and ultimately A mixture of 3D printing has been created, whose intellectual property will be registered to the municipality as the owner of the mix rights.
Green Building Standards
The building has been implemented in accordance with the requirements of sustainability and green building standards.It features efficient insulation systems, innovative wall printing and increased utilization of voids inside the wall, which helps to isolate the building thermal energy consumption, in addition to the development of solutions to connect Services within the printed walls, which include all services of the building, electricity, water, communications, air conditioning and information systems technologies.
3D construction reduces costs by up to 60%.
