Assessment of the types of public building maintenance contracts in Saudi Arabia

The study revealed that Fixed Price, Cost Plus and Purchased Labour contracts are the top three maintenance contracts adopted whilst Unit Price, Cost Plus A Percentage Fee contracts are alternatives used in the Kingdom. Some other types of maintenance contract were thought to be inappropriate by ministry departments.     

旧工业建筑的再利用

旧工业建筑与其他旧建筑物相比,具有建筑主体结构坚固,空间高大灵活;体量大,拆除或新建对环境造成的影响大;具有其独特的设计理念和美学价值等特点,从而成为旧建筑再利用过程中一种重要的建筑类型。 本文通过对101厂房再利用案例设计过程的分析,对旧工业建筑再利用的目标、更新程序、方式、策略等方面进行具有可操作性和推广性的探索。

Automated model generation for performance engineering of building automation networks

Large technical systems need to be designed both reliable and efficient. Specialized design tools offer therefore a simplified, abstract design and extend details autonomously in the background. Analytic and simulation based models could improve the quality by testing and dimensioning the design before implementation, but setting up the necessary models is time-consuming and expensive. Therefore many developers ask for analysis tools which are able to create their models from the available information in the design tools. This paper presents such an automated modeling approach basing on an existing design database at the example of a network analysis for building automation fieldbuses. The process of automated modeling is unfolded, and the potentials and limitations are discussed.     

Facilities management, building maintenance and modernization link

The widening of interest and scope of property management and maintenance has attracted a greater diversity of professional disciplines into facilities management. Dr Quah, coordinator of CIB W70 on Management, Maintenance and Modernization of Building facilities, expresses her personal views on the current fascination with the subject.

攀钢高炉焖砂口试验

分析了高炉冶练钒钛磁铁矿炉前砂口损坏的原因。对新型砂口泥进研制，同时改进了套砂口工艺，满足了攀钢高炉焖砂口的需要。攀钢高炉采用闷砂口工艺后，从根本上解决了铁水带渣问题，提高了铁水的洁净度。     

高层建筑损伤识别中的补偿算法

本文在已有研究工作的基础上，提出了处理激励测量信息不完备情况下的补偿算法。此方法主要针对高层建筑动力检测中强迫激励的情况，是一种基于时域的识别方法，该方法实际上是利用客观工程实际中结构系统激励所具有的物理持征作为识别计算的辅助条件，来解决测量信息的不完备性问题。算例分析表明了该方法的可行性。     

转运站框架式厂房的爆破拆除

合山电厂转运站待拆五层钢筋混凝土框架式厂房西侧与被保护的引风机房相隔仅 0 3m ,北侧与工具房相连 ,南侧与需要保护的油池相邻。爆破切口布置在二层 ,并把最后一排柱的爆破部位提高到引风机房顶部以上 0 5m处 ,避免了后坐对引风机房的影响。通过预处理 ,将厂房与工具房分离。架设防护结构 ,阻挡飞石 ,保护了油池。文中介绍了爆高和爆破参数的选择、预处理、起爆破网路设计和安全防护措施。     

浅谈南水北调工程中招标代理机构的自身建设

在市场经济条件下,随着水利工程建设市场的不断规范和完善,招标代理机构如何在市场竞争中开展招标代理业务,其自身建设就显得尤为重要。现结合南水北调工程实际,提出了招标代理机构应从法律意识、诚实信用、专业特长、激励机制和沟通协调等5个方面加强自身建设,以便能在南水北调工程建设中更好地发挥作用。
