Highlighting 2 Typical Flat Slab Spans Commonly Used for Social Housing

Flat slabs without beams are one of the construction material solutions most widely chosen by developers today. This is not only due to their outstanding advantages but also because they consistently meet the most stringent requirements of construction projects.

With today's construction trends and government support policies, social housing projects are gradually becoming more accessible to low-income workers, providing them with essential housing amenities, ensuring better living conditions, and increasing the added value of the community.

Flat slab solutions without beams are considered one of the material solutions prioritized by developers when constructing social housing projects because of their reasonable cost and environmentally friendly properties. Join LPC as we take a look at the 2 flat slab spans without beams most commonly used in social housing projects.

Social Housing – A Trend in the Future Construction Market

In recent years, thanks to government policies and support, together with advances in science and technology, industrial zones have been developing across many provinces and regions. This has created a greater demand for social housing projects to serve low-income workers, particularly those working in industrial zones.

Social housing refers to housing developed and operated by the government or relevant organizations at affordable prices for low-income households, meeting residents' needs for housing and basic, stable amenities. Social housing is typically built on pre-planned land and allocated to people with genuine housing needs.

Since these homes are sold at affordable prices, developers carefully consider the selection of materials with suitable costs while still ensuring structural integrity, safety, optimal functionality, and cost efficiency for the project. At the same time, green construction is being encouraged by the government, so social housing projects are also being evaluated from this perspective.

Flat Slabs Without Beams for Social Housing Projects

As affordable projects, social housing developments prioritize the selection of optimized materials. These projects often favor flat slab solutions without beams because of their outstanding advantages and suitability for this type of construction.

Recognized as an environmentally friendly material solution with standardized testing and inspection results, Ubot flat slabs without beams have been successfully used in numerous large-scale social housing projects, including Ecohome Phuc Loi Social Housing in Long Bien. The project received the “Green Building” award at the Transformational Business Award 2018, as well as Cat Tuong Smart City Social Housing – Thong Nhat Smart City in Yen Phong, Bac Ninh. The project was visited by Prime Minister Pham Minh Chinh in July.

There are also 3 key reasons for applying flat slabs without beams to social housing projects:

• Cost Optimization – High Economic Efficiency: By using flat slabs without beams, developers can reduce construction costs by 10% to 15% compared with conventional slab construction and reduce steel consumption by 10% to 20%. This helps optimize material and labor costs for the project.
• Space Optimization – Functional Efficiency: With spans of up to 20m, developers can optimize the usable space of the project and increase economic efficiency. With the same overall building height, the project can accommodate additional floors because the depth of the floor-and-beam system is reduced.
• Green Material – Environmentally Friendly: The Ubot flat slab solution is certified as an environmentally friendly material solution, helping improve the sustainability performance of construction projects.

2 Flat Slab Spans Without Beams Commonly Used in Social Housing

These projects are designed according to standards to ensure technical and social infrastructure requirements in accordance with the regulations for each type of urban area. Currently, many agencies under the Ministry of Construction have reviewed the UBOT flat slab solution without beams, including VNCC, Coninco, IBST, CDC, and others. Numerous projects have also been appraised by competent authorities under provincial departments, the Construction Activities Management Agency under the Ministry of Construction, and the Department of Barracks under the Ministry of National Defense.

The two spans most commonly used for social housing are typically 7–9m. These two spans provide optimal efficiency for developers not only in terms of architecture, structural performance, and economics, but also in terms of usability, maximizing the advantages of the Ubot flat slab solution for the project.

In addition, the 7–9m span range is considered optimal and suitable, while also meeting the design and review standards for social housing projects.

Cat Tuong Smart City Social Housing Project in Yen Phong, Bac Ninh is a typical example of this span. With a total construction area of 9.7 ha, the project used approximately 190,000 m² of Ubot flat slabs without beams with a 7m span — a typical span for social housing projects.

The Cat Tuong Eco Social Housing Project in Bac Ninh City, where LPC served as the main contractor for design consultancy and transfer of the Ubot flat slab solution without beams, also used a 7.5m span to optimize space while ensuring structural integrity and technical standards.

Ubot flat slabs have demonstrated their significant position by being applied in numerous prominent social housing projects. We hope that this information provides developers and design consultants with reliable reference material, helping them find an experienced implementation partner to maximize the inherent advantages of flat slab solutions without beams.
