Study on Application of ''Design and Build'' Contract Mode

The 'Design and Build' contract mode is a new contract and managerial approach, to which more and more attention has been paid. Now it becomes the contracting tendency in the international construction market. In this paper, the basic theories and method of the 'Design and Build' mode are widely and systematically studied. It specifies the intention of the 'Design and Build'contract mode, existing problems and corresponding countermeasures as well as its developing direction.     

Estimating harvest costs and projecting quantities of logging residues for small-scale forestry in Nasushiobara,Tochigi Prefecture,Japan

We used GIS on a regional scale to estimate and compare supply potentials and costs of small-scale logging systems, a mini-forwarder and a 4-ton truck operated by private logging contractors, and manual logging and a light truck operated by individual forest own- ers, with the mechanized operational system of the Forest Owners＇ Asso- ciation. Total potential yields of timber and logging residues were esti- mated as 418,895 m3 and 254,962 m3, respectively. The economic bal- ances were estimated and available amounts were projected as supply potentials from profitable sub-compartments. As a result, available amounts of timber and logging residues were estimated at 375,466 m3 （89.9%） and 203,850 m3 （80.0%）, respectively. Because their transport expenses were lower than for other systems the most profitable sub-compartments were operated by private logging contractors who sold logging residues at a plant. The profitable sub-compartments operated by individual forest owners were few because the extracting distances were usually greater than 20 m. Raising logging residue prices from 3,000 yen·m-3 to 4,080 yen·m-3 or 6,800 yen·m-3, and establishing forest roads, which reduced some extracting distances to less than 20 m, increased the number and area of profitable sub＊compartments, and increased available amounts of logging residues.     

农村土地承包经营权要素编码的关键问题及解决途径

为准确使用NY/T 2538-2014、规范农村土地承包经营权确权登记颁证工作,针对目前农村土地承包经营权要素编码中存在的县级段代码和乡级段代码编制、发包方编码、承包方编码、特殊区域编码等关键问题,采用文案调查法和实地调查法进行深入剖析,并给出了问题的解决途径。结果表明:1)县级段代码和乡级段代码应以目前正在开展的农村土地承包经营权确权登记颁证工作作为时间节点来进行编码,并采用民政部公布的行政区划代码;2)发包方应按照农村土地所有关系进行编码,并且发包方编码在承包期内保持稳定;3)承包方应视为权利人来进行编码,其编码取决于是否与发包方签订承包合同;4)农村土地承包经营权要素编码与特殊区域内农村土地承包管理方式无关,应按照农村土地承包经营权要素的内在关系进行编码。通过剖析上述关键问题,研究可进一步深化对农村土地承包经营权要素编码的认识,促进NY/T 2538-2014在农村土地承包经营权确权登记颁证工作中的规范应用。     

国际EPCC项目运行管理中存在的问题

以苏丹六区项目运行过程中出现的问题为依据,按照项目运行管理流程,详细分析了国内承包商在国际EPCC项目运行管理过程中基础数据资料、供货商名单、文件批复流程、项目各参与方沟通方式和项目运行管理程序等方面所出现的问题及存在的隐患,总结了从项目招投标阶段至投产试运行的整个过程中承包商在基础资料收集、招标文件响应、总承包和分包合同管理及项目运行流程管理等方面应当注意的细节问题.在国际EPCC项目中,承包商应认真研读招标文件和合同文本,规范项目管理模式和流程,细化分工,明确权责,以期尽可能在此类项目运行管理中规避风险、消除隐患,达到项目预期收益.     

Analysis of the Type of Contract Price in Construction Projects

In the construction projects, the contract, which is the most important behavior norm, determines the rights and responsibilities of client and contractor. All engineering activities aim at implementing and carrying out the articles of the contract. However, as the key component of the contract, the type of contract price determines the distribution mode of most of the engineering risk between client and contractor. In this paper, the most popular types of contract price used in the international construction projects are introduced. The advantages and disadvantages of each type and the distribution mode of the engineering risk between client and contractor are analyzed. At the end, some advice are given to the clients that they should choose the proper type of contract price and have innovation according to the characteristics of certain project and the situation of themselves.

Evaluation Method Based on Artificial Neural Network in Contractor Prequalification of Tenderers

Both tenderees and tenderers attach much importance to contractor prequalification before bidding because it plays important roles for both and so far the Score Method has been widely used in our country. But the weights in the method are man-made, which may be affected by personality inevitably. In order to avoid this influence, this thesis will introduce another method based on artificial neural network. This thesis expatiates the principle of artificial neural network, and analyzes the characters of prequalification. Then, the author sets up the mathematics model. In the end, the author analyzes this method by an example.
