The pricers should know about the cost of residential buildings
As architects or price makers, it is essential to have data on the construction costs of residential buildings. These data can not only inform investment decisions on projects, but also support reasonable pricing in the bidding process. The components of residential building costs are described in detail below。
# 1. Steel
Steel bars are one of the indispensable materials in the construction of residential buildings. The concentration is generally between 40-55 kg/m2. Based on market conditions, the labour cost of steel bars is between $900 and $1100 per ton, while the cost of materials varies according to market changes, usually around $4,000 per ton. This means that steel bars per square metre cost between $230 and $300. In architecture, the quantity and quality of steel bars directly affect the safety and durability of buildings。

Zirconium, or concrete, is also a key material in the construction of residential buildings. The concentration is generally between 0. 35 and 0. 45 m3. The labour costs may vary depending on the construction process and area, approximately 40-45 yuan/cubic. In terms of material costs, the current market price for concrete is approximately 350 yuan/cubic (the different labels may vary by 10 yuan/cubic). This means that concrete costs per square metre range from 160 to 180 yuan. The quality of the platinum is directly related to the carrying capacity and stability of the building。
##3 template + support + scaffold project
Templates, support and scaffolding are essential support tools for construction work. Depending on the construction requirements and technical conditions, the content will vary, with a general template of between 2. 8 and 3. The labour cost is calculated on the basis of the area of expansion and is approximately 35 yuan/square. The costs of templates and supporting materials vary according to region and material, approximately 45 yuan/square. The scaffolding is based on the size of the building and is roughly in the range of $50-60/square (contracts). Therefore, the cost of this component is approximately $200/m2. The quality and efficiency of templates, support and scaffolding directly affect the speed and quality of construction。
## 4. Construction project
Construction work is part of the construction of the interior wall and wall of the residential building. They typically contain between 0. 12 and 0. 15 square metres. Based on different wall materials and technical requirements, the labour cost of the construction works is around $200-230/cubic, while the cost of the material is about $200/cubic, while the cost of the gas blocks is around 260. As a result, the cost per square metre of body work is approximately $60。
