Analyzing the Cost of High-Rise Buildings after Second Design Based on the Bill of Quantity Valuation Mode
The second design of construction drawings is an important part for building. It is not only a simple analysis and a modification of the drawings, but is the purpose to save cost using re-designed based on construction plan and techniques. For this purpose and other advantages of second design, the current large-scale projects, especially high-rise buildings, are required for secondary design. This article mainly introduces the second design, and uses the value engineering and the weighted average method to analyze the problem of cost savings and allocation. It proposes the approaches and methods of cost savings through the second design, obtains a reasonable method of allocation ratio calculation and general distribution ratio, as well as provides a strong reference to improving the economics of high-rise buildings.
