本文记述了原民国中央博物院(简称央博)在其营建过程中尺度与技术探析过程。自 1929 年《首都计划》中提出对南京公共场所建设指示后,南京国民政府教育部于 1933 年设立中央博物院(央博)筹备处,自此征集其设计方案。在其设计竞赛及修改的过程中,遇到的两类矛盾,一类是传统规制和做法与功能要求的矛盾,另一类是传统规制和做法与现代材料与结构技术的矛盾。前者涉及空间的构建的设计,后者涉及到施工的技术与做法。在中西文化与技术碰撞的近代,央博的营建同样面对材料、度量单位等方面的转译,其在形式与材料、结构方面的碰撞中采取的解决方案值得借鉴。 相似文献

One of the major methods of managing construction risks in the Nigerian construction industry is the insurance method. On the basis of data from some selected construction sites in Nigeria, this paper evaluates the effectiveness of the method. Also it identifies, through a questionnaire survey, the various insurable construction risks perceived to be encountered in the Nigerian construction industry and the types of insurance policy employed in managing them. High importance is placed by the construction industry on site security, construction risk, and health and welfare requirements, and the use of an all-risk insurance policy is the most prominent method for managing the identified risks. Finally it is concluded that there is a correlation between insured sum and actual replacement cost when there are losses or damages. However, the insurance claims settled could cater for only 61.1% of the replacement cost of on-going construction works studied. 相似文献

As construction activity has a significant impact on the environment it is vital to consider how to improve the environmental performance of organizations in the construction industry. The ISO 14000 series of standards on environmental management provides construction enterprises with the tool to address in a structured manner the adverse impacts of their operations and to attain sustainable construction. In this study, a survey was conducted to ascertain the perceptions of construction enterprises in Singapore on the impact of the implementation of ISO 14000 on their operations. Major problems were identified, and recommendations are made for the future development of environmental management systems (EMS) in the Singapore construction industry. 相似文献

It is widely recognized that building design has a significant impact on construction productivity and quality. Constructability rules are one way of transferring construction knowledge to building designers. These rules are statements, such as ‘design for minimum time below ground’, which encapsulate a specific aspect of construction best practice. Although constructability rules are relatively easy to formulate and/or obtain, there is little evidence of their successful application. Indeed, architects continue to be held responsible for productivity and quality problems because of their lack of construction knowledge. This paper reports research that informed and included the development of guidelines for successful application of constructability rules to bespoke buildings - those being buildings that are designed to fulfil the requirements of one particular client and/or a single specific location. Findings suggest that there are actions that can be taken to widen the application of rules and increase their success. Potential sources for rules are described. Guidelines are introduced, and information about how they can be actioned by different construction organizations is provided. 相似文献
