Based on the prediction of both the external economic factor of market and the internal management factor of enterprise which influence the construction cost directly , the control criteria for the project construction cost can be precisely determined ; by which not only the blindness of cost payout can be avoided , and the scientific prediction cart also be enhanced with the realization of the target control of the management cost concerned 摘要项目施工成本预测的内外因素的主要内容是,通过对影响成本变化的外部市场经济因素和企业内部管理因素的预测,可以较准确地确定工程施工成本的控制标准,克服成本支出盲目性,提高科学预见性,实现管理费的目标控制。
The paper establishes safety control criterion of subgrade deformation of steel structure workshop in soft soil region in terms of design criteria of subgrade deformation in soft soil region and the classification standard on reliability of steel structural member , which offers a security of structural safety 根据软土地区地基变形的设计规定和钢结构构件可靠性的分级标准,建立了软土地基钢结构厂房的地基变形安全控制标准,为保证地基变形作用下的结构安全提供了依据。
