Research On Influencing Factors And Control Measurements Of Cost About Telecom Buildings In Chongqing

In recent years, the scale of Chongqing Telecom Corporation was expanding constantly, with communication capacity and communication service improved continuously and telecom portfolio increased severely. So there have being a great demand for telecom buildings all the time. With the rapid development of business scale, applications of new technology and new manage conception make operation cost of Telecom Corporation reduced gradually, but the increasing cost of basic facilities such as telecom buildings was an unharmonious factor. Therefore reducing the cost of telecom buildings becomes the urgent task for Telecom Corporation at present.In order to analyze the high cost of Chongqing telecom buildings and to present measures for decreasing the cost of buildings, this article carried on statistical analysis of the completed telecom buildings and classified information of all kinds of telecom buildings, which included area, cost, structure type and time of completion, and then analyzed the impacts of the information on the cost of telecom buildings. Taking the function of the telecom buildings and the design requirement into account, some methods to controlling cost of the project were proposed. On the basis of statistical analysis, two typical telecom buildings were selected for structure analysis, so as to put forward improved schemes of structural design. And then, change of material consumption was calculated and change of structural performance was also compared respectively. The detailed contents include the following several items:(1) Information database of telecom buildings in Chongqing was established.Considering particular characteristics (various styles, large quantity, extensive locations, various constructions, heavy loads on floor, high seismic fortification criterion, great differences of the cost, and expansive time of completion) of telecom buildings in Chongqing, the statistical information was analyzed and the information database of telecomm buildings in Chongqing was established as the foundation and as a tool of further research.(2) Requirements and characterizes of telecom buildings were generalized.Firstly, telecom buildings were introduced summarily, and then requirements and characterizes of telecom production buildings were introduced particularly. Architecture requirement and construction requirement induce the requirements and characterizes of telecom buildings.(3) Influencing factors on the cost of telecom buildings were analyzed.With continual renovations of the telecom craft and telecom equipment, the design requirements of telecom buildings were being improved constantly. Based on the analysis of the standards and codes for telecom buildings and the statistical results of telecom buildings, influencing factors on cost of telecom buildings were provided and obvious characters of the factors were analyzed. That offered guidance for typical buildings calculation and for construction cost reducing.(4) Optimization design of typical telecom buildings and comparison analysis.The chapter includes two parts. In the first part, optimized schemes of the typical telecom buildings were provided and the consumptions of reinforcing bar and concrete were calculated respectively, which were compared with those of original structures.The second part included analysis of the original structure based on performance -nonlinear static analysis (Pushover). Performances of different structures were examined in different design conditions in order to certify the influencing factors on construction cost and the effective measures to reducing the construction cost.
