In the warm heart of the building, water supply, drainage and heating works are like the blood of life, maintaining the comfort and health of the occupants. The following is an analysis of the cost trend of water supply, drainage and heating projects in 2024, revealing the subtle changes in the cost of various projects through the comparison of the unilateral cost and the cost index of the base period.
1. **Multi-storey residential water supply and drainage system renovation project**:
- The unilateral cost of the base period in June 2024 was 103 yuan/m², and the cost index in December of the same year was 123.84, an increase of 0.11% month-on-month. This indicates a slight increase in the cost of multi-storey residential plumbing and sewerage retrofit works, possibly due to a slight increase in material or labor costs.
2. **High-rise residential water supply and drainage system renovation project**:
- The unilateral cost of the base period was 74 yuan/m, and the cost index at the end of the year was 126.50, an increase of about 0.13% month-on-month. The cost of renovating the water supply and drainage system of high-rise residential buildings also showed a slight increase, which may be related to the construction difficulty and technical requirements unique to high-rise residential buildings.
3. **Multi-storey Residential Heating System Renovation Project**:
- The unilateral cost of the base period was 117 yuan/m, and the cost index at the end of the year was 108.83, an increase of about 0.09% month-on-month. The slight increase in the cost of renovation works for multi-storey residential heating systems may be due to changes in energy prices or the cost of heating equipment.
4. **Multi-storey residential heating sub-household heat metering system renovation project**:
- The unilateral cost of the base period was 22 yuan/m, and the cost index at the end of the year was 113.83, an increase of about 0.12% month-on-month. There has been a slight increase in the cost of retrofitting a sub-household heat metering system, which may reflect the cost of applying energy-saving technologies and smart metering equipment.
5. **Boiler room coal-to-gas project**:
- The unilateral cost of the base period was 7043 yuan/m², and the cost index at the end of the year was 114.24, an increase of about 0.08% month-on-month. The slight increase in the cost of coal-to-gas conversion projects may be related to fluctuating natural gas prices or upgrading conversion equipment.
**Summary**:
The cost data of water supply, drainage and heating projects in 2024 shows that the cost of most projects shows a slight upward trend, with an increase of less than 0.13%. This trend may be influenced by many factors such as energy price fluctuations, the promotion of new energy-saving equipment, and the improvement of construction technology. For project managers, paying attention to these subtle cost changes will help to predict and control costs more accurately, optimize resource allocation, and also help promote the process of energy conservation, emission reduction and intelligent transformation. In the future construction of projects, we should continue to pay attention to market dynamics and flexibly adjust strategies to maximize cost-effectiveness and optimize social benefits.
