In 2025, the number of old buildings in Seoul increased by 61.2% compared to the previous year. Considering the government's recent will and policy to quickly support urban renovation projects, demand for ready-mixed concrete is expected to increase significantly.
- Related construction such as replacement, demolition, and repair of old facilities is actively carried out in the northeastern and southwest areas of Seoul.
- Among the total buildings, old buildings that are 30 years old account for 61.2%, which means the aging of the city.
- The aging rate in downtown Seoul is 41.4%, at least 0.4%p higher than other living areas by up to 16.2%.
In fact, old buildings in Seoul are increasing mainly in residential facilities, and 114 of the urban renovation projects under way are expected to inevitably supply a large amount of ready-mixed concrete due to the high probability of construction.
- The provisional estimate of ready-mixed concrete during the period when there are many old buildings is 65,439,341.1㎥, which is 89.8% of the time when the shipment of ready-mixed concrete from Seoul and Gyeongin was the highest.
- The demand for ready-mixed concrete at a time when urban maintenance projects are expected to increase rapidly was 2,016,000㎥, accounting for 91.9% of the total production of ready-mixed concrete factories in Seoul.
- There is an urgent need to come up with realistic measures to expand production and supply for ready-mixed concrete delivery.
The successive demolition of ready-mixed concrete plants in Seoul has resulted in a decrease in production and a gap in the supply chain. In addition, restrictions on vehicle traffic and operation in urban areas also act as a factor limiting the supply of ready-mixed concrete.
- Since only two ready-mixed concrete plants in Seoul will operate, it creates supply chain gaps in the downtown area, the northeast area, and the southwest area along with a decrease in production.
- Restrictions on vehicle traffic and driving lead to a decrease in productivity, as well as a decrease in daily supply, allowing work only for a certain time.
The government has implemented several systems and eased regulations for stable ready-mixed concrete deliveries. However, the expected effect is expected to be less than expected as the changed supply chain for ready-mixed concrete deliveries is not taken into account.
- Some contributions are expected to stabilize the delivery of ready-mixed concrete by implementing the priority delivery system and the installment delivery deadline system at public construction sites. However, problems such as lack of objectivity and equity for the selection of targets, and increased complexity in contracts and management are inherent.
- Areas that cannot produce all of them through on-site deployment plants should make efforts to secure supplies from outside and manage the operation of on-site production equipment. Therefore, it is expected to introduce only a small part of Seoul's urban renovation project sites.
Putting together the above, various policies and self-rescue efforts are required as demand for ready-mixed concrete is expected to increase significantly within the next few years.
- Government-level and private-level ready-mixed concrete have similar problems. Policy efforts should establish standards for coordinating and strengthening supervisory authority for delivery instruction and implementation, introducing a performance-based contract system, improving quality, and clarifying responsibility.
- Self-rescue efforts are required in consideration of policies for the development and diffusion of various deployment plants, cost reduction, and eco-friendliness.
- In order to spread the site layout plant, it is also necessary to adjust the layout standards of contractors and supervisors and to allocate costs.
- Exceptional provisions should also be considered that allow temporary increases in production to address delays in delivering ready-mixed concrete and instability in supply and demand at sites with limited production of field placement plants.
- A consensus should be formed for "rent-production-operation and maintenance" by mobile deployment plants to settle into businesses suitable for the changed supply chain.
