【摘要】：G港地处珠江东北岸，珠江与东江汇合处，港区内建有专用铁路与广深铁路相连，水陆交通方便，毗邻广州两个主要火力发电厂，是华南地区煤炭运输的主要中转站。码头拥有7万吨级卸船泊位2个，年设计卸船能力为1400万吨。目前码头拥有6台桥式卸船机，由德国MAN公司于1992年制造投产，现电控系统采用瑞典ABB直流调速控制系统，于2003年初改造使用，已满负荷运行10年左右，故障频繁且维修备件不足，迫切需要对其进行更新改造，以满足生产需要。 5号卸船机是码头6台卸船机之一，2013年下半年公司通过公开招标对其控制系统进行了更新。项目于2013年7月底完成招标，并与中标单位签订合同，2014年1月底完成施工调试。但由于招标时考虑不周，导致项目实际施工工期延迟一周，施工内容与合同存在出入，现场施工影响了码头正常的生产。本论文根据5号卸船机控制系统更新项目实际施工过程所出现的问题，针对5号卸船机控制系统更新项目的发包、招标、评标管理过程进行探讨，通过介绍卸船机控制系统更新项目招评标概况及评标现状，对G港本次招评标过程发现的问题进行分析，借鉴其它工程建设领域成功的招标评标经验，对本次卸船机控制系统更新项目招评标过程中存在的问题进行研究，从改进招标流程设计和利用层次分析法对承包商进行选择等方面进行详细阐述，运用项目管理理论给出卸船机控制系统更新项目招评标的改进方案。希望能够为其它几台卸船机更新改造时选择更合适的施工承包商，，更好的解决施工现场问题，在保证施工质量的前提下，高效的利用资金，缩短施工时间，节约社会资源，提高卸船机更新改造效率。
[Abstract]:Port G is located on the northeast bank of the Pearl River, where the Pearl River and Dongjiang River meet. The port area is connected by a dedicated railway to the Guangzhou-Shenzhen Railway. The water and land transportation is convenient. It is adjacent to two major coal-fired power plants in Guangzhou. It is the main transfer station of coal transportation in south china. The dock has 2 berths of 70, 000 tons of ships and 14 million tons of designed unloading capacity per year. At present, the terminal has 6 bridge type ship unloader, which was manufactured and put into production by MAN company of Germany in 1992. Now the electric control system adopts Sweden ABB DC speed regulation control system, which was reformed and used in early 2003. It has been running at full load for about 10 years, with frequent faults and insufficient maintenance spare parts, so it is urgent to renew and transform it to meet the needs of production. Ship unloader No. 5 is one of the six ship unloaders in the dock. In the second half of 2013, the company updated its control system through open tender. The project was completed in the end of July 2013. And signed a contract with the winning bidder, and completed the construction commissioning at the end of January 2014. However, due to inadequate consideration in the bidding process, the actual construction period of the project was delayed by one week, and the construction content was different from the contract. The site construction has affected the normal production of the dock. According to the problems in the actual construction process of the No. 5 ship unloader control system renewal project, this paper aims at the contract and bidding of the No. 5 ship unloader control system renewal project. The management process of bid evaluation is discussed. By introducing the general situation of bid invitation and evaluation of the renewal project of ship unloader control system and the present situation of bid evaluation, the problems found in the bidding and evaluation process of G Port are analyzed, and the successful bidding and evaluation experience in other engineering construction fields is used for reference. This paper studies the problems existing in the bidding evaluation process of the ship-unloader control system renewal project, and expounds in detail the improvement of the bidding process design and the selection of the contractor by using the Analytic hierarchy process (AHP). Based on the project management theory, this paper gives an improved scheme of bidding evaluation for the renewal project of ship unloader control system. It is hoped that more suitable construction contractors can be selected for the renewal and transformation of several other ship unloaders, so as to solve the construction site problems better. Under the premise of ensuring the construction quality, the capital is used efficiently, the construction time is shortened, the social resources are saved, and the efficiency of the renewal and transformation of the ship unloader is improved.
