Project Budget Monitor and Control

Author:Yin Guo-li

Nationality:American

Derivation:Management Science and Engineering. Montreal: Mar 20, 2010 .

With the marketing competitiveness growing, it is more and more critical in budget control of each project. This paper discusses that in the construction phase, how can a project manager be successful in budget control. There are many methods discussed in this paper, it reveals that to be successful, the project manager must concern all this methods.

1. INTRODUCTION

The survey shows that most projects encounter cost over-runs (Williams Ackermann, Eden, 2002,pl92). According to Wright (1997)'s research, a good rule of thumb is to add a minimum of 50% to the first estimate of the budget (Gardiner and Stewart, 1998, p251). It indicates that project is very complex and full of challenge. Many unexpected issues will lead the project cost over-runs. Therefore, many technologies and methods are developed for successful monitoring and control to lead the project to success. In this article, we will discuss in the construction phase, how can a project manager to be successful budget control.

2. THE CONCEPT AND THE PURPOSE OF PROJECT CONTROL AND MONITOR

Erel and Raz (2000) state that the project control cycle consists of measuring the status of the project, comparing to the plan, analysis of the deviations, and implementing any appropriate corrective actions. When a project reach the construction phase, monitor and control is critical to deliver the project success. Project monitoring exists to establish the need to take corrective action, whilst there is still time to take action. Through monitoring the activities, the project team can analyze the deviations and decide what to do and actually do it. The purpose of monitor and control is to support the implementation of corrective actions, ensure projects stay on target or get project back on target once it has gone off target。

3. SETTING UP AN EFFICIENT CONTROL SYSTEM

For the purpose of achieving cost target, the manager need to set up an efficient management framework including: reporting structure, assessing progress, and communication system. The employees' responsibility and authority need to be defined in the reporting structure. The formal and informal assessing progress can help getting a general perspective between reality and target. It is significant to help identify what is the risk and should be monitored and controlled. Project success is strongly linked to communication. The efficient communication system benefit for teamwork and facilitate problem solving ( Diallo and Thuillier, 2005 ).

4. COST MONITOR AND CONTROL

4.1 Ranking the priority of monitoring

In construction phase, many activities are carried out based on the original plan. It is need to know what kind of activities or things are most likely to lead the project delay and disruption. Therefore, the first step is ranking the priority of the activities. Because the duration of a project is determined by the total time of activities on critical path, any delay in an activity on the critical path will cause a delay in the completion date for the project (Ackermann Eden, Howick and Williams,2000,p295). Therefore, the activities on critical path should firstly to be monitored and controlled. Secondly, monitoring the activities with no free float remaining, a delay in any activity with no free float will delay some subsequent activity inevitably. These subsequent delays will discomfit the resource schedule significantly. Some resources are unavailable because they are committed elsewhere. Thirdly, monitoring the activities with less than a specified float, because if an activity has very little float, it might use up the time before control decision is made once such an activities has a variance with the target. Fourthly, managers should monitor high risky activities. High risky activities are most likely to overspend. Fifthly, managers should monitor the activities using critical resource. Some resource is critical because they are very expensive or limited (Cotterell and Hughes, 1995).

4.2Methods of cost control

The main cost of a project includes staff cost, material cost and delay cost. To control these cost, managers should first set up a cost control system to:

a) Allocate responsibilities for administration and analysis of financial data

b) Ensure all costs are properly allocated against project codes

c) Ensure all costs are genuinely in pursuit of project activities

d) Check that other projects are not using the budget.

Then, managers should monitor and control change to the project budget. It means the following things:

a) Concerned with key factors that cause changes to the budget

b) Controlling actual cost changes as they occur

- Monitor cost performance to detect variances

- Record all appropriate changes accurately in the cost baseline

- Preventing incorrect, unauthorized changes being included in the cost baseline

- Determine positive and negative variances

- Integrated with all other control processes (scope, change, schedule, quality) As a project is dynamic, sometimes the project managers know the project is going out off target by monitoring, but don't know the best action to take. In this circumstance, net present value (NPV) should be used as an ongoing monitor and control mechanism, because NPV takes account of the time element and discounts future cash flows, it is the result of the time effect on cash

4.3 Change monitor and control

Voropajev (1998) states that dynamic changes of project environment will influence the process of project implementation, the project itself and may cause heightened risk. When carried out some activities, the methods different from that in the original plan must be used to keep the process moving forward (as experienced under practice). Therefore, changes are inevitable and need to be managed during project life-cycle (Voropajev. 1998,p 16- 17) .An effective change control system should be established to ensure change procedure is clear and unambiguous and easy for employee to request a change. And the following things need to be concerned:

a) Monitoring and forecasting most probable changes Key factors that generate change to ensure good results; make sure that change must be checked by suitable person.

b) Changes should take place once it is approved and be monitored to check whether it worked as expected

c) All changes in project should be recorded in the project documentation (Voropajev, 1998,pl8).

5. CONCLUSION

This article shows the best methods of budget control. First, an efficient control system must be set up. Secondly, It is required to recognize and rank the important factors affecting budget target. Thirdly, manager should combine different control techniques to reach the success of a project.

随着市场竞争的激烈性越来越大,在每一个项目中,进行成本控制越发重要。本文论述了在施工阶段,项目经理如何成功地控制项目预算成本。本文讨论了很多方法。它表明,要取得成功,项目经理必须关注这些成功的方法。

1.简介

调查显示,大多数项目会碰到超出预算的问题(Williams Ackermann, Eden, 2002,pl92)。据Wright(1997)的研究,一个好的经验法则就是相比首次成本预算至少会增加50%(Gardiner and Stewart, 1998, p251)。这表明,项目是非常复杂并且充满挑战的。很多意想不到的因素会导致项目成本的增加。因此,许多科学技术和方法被应用于监测和控制成本来促使项目的成功。在这篇文章中,我们将讨论在施工阶段,项目经理如何才能成功控制预算成本。

2.项目控制和监测的概念和目的

Erel and Raz (2000)指出项目控制周期包括测量成本是实际情况,将施工成本的实际值和计划值进行比较,对比较结果进行分析,并采取适当的措施来纠正偏差。项目在施工阶段的监测和控制对于项目的成功是至关重要的。为了采取正确的纠偏措施需要建立项目监测机制,同时这样做也可以有时间来采取措施。通过监测手段,项目团队可以分析偏差产生的原因以及决定纠偏措施并采取行动。监控的目的就是纠偏措施的实施,确保项目控制在计划目标内或者使已经偏离计划的回到目标范围内。

3.建立一个有效的控制体系

为了实现预算成本的目标,项目管理者需要建立一个高效的管理框架,包括:报告的结构,评估的进展情况以及沟通体系。在报告结构中,雇员的责任和权力应该要清楚地被定义。正式的和非正式的评估可以帮助实际和目标之间大体上保持一致,且这对于确定什么是风险以及哪些需要被监测和控制是非常有帮助的。项目成功与良好的沟通密切相关,一个高效率的沟通体系有利于团队协作并促进问题的解决( Diallo and Thuillier, 2005)。

4.成本费用的检测和控制

4.1对检测的优先顺序进行排序

在施工阶段,很多施工活动是基于原来的计划。它需要清楚什么样的活动或者哪些东西是最有可能导致项目延误和不受控制的。因此,第一步就是要对这些

活动进行优先排序。由于项目的工期是由关键路径上的关键工作的总时间决定的,任何关键路径上工作的延迟将导致项目工期的拖延

(Ackermann Eden, Howick and Williams,2000,p295)。因此,关键路径上的工作应该首先进行检测和控制。其次,检测没有自由时差浮动的工作,任何没有自由时差工作的延误将导致其后续工作的拖延,这些后续工作的延误将对资源分配安排带来影响,有些资源被分配到特定的工作是不可以变更利用的。第三,检测具有较少浮动时间的工作,因为,如果一个工作具有非常少的浮动时间,那么当它偏离目标的时候很有可能在还没有采取控制措施前就将浮动时间用完了。第四,项目管理者应该检测高风险活动,高风险活动最有可能超支。第五,管理者应该检测项目活动中使用的关键资源,有些资源由于是非常昂贵和有限的而至关重要(Cotterell and Hughes, 1995)。

4.2成本控制的方法

一个项目的主要费用包括员工成本、材料成本以及工期延误的成本。为了控制这些成本费用,项目管理者首先应该建立一个成本控制系统:

a)为财务数据的管理和分析工作落实责任人员

b)确保按照项目的结构来合理分配所有的成本

c)确保所有成本都是项目进展过程中各项活动的真实支出

d)检查其它工程项目没有使用此项目预算

然后,项目管理者应该对项目预算进行监督和控制变更。这意味着以下几点:

a)关注可以引起成本变化的主要因素

b)控制实际成本的变化

--监测成本发生情况来发现它的变化

--在成本控制线上准确地记录所有恰当的成本变动

--为防止出现错误,没有经过允许的成本变化也应该体现在成本控制线上

--确定积极地和消极的成本变化

--与其它控制目标(范围、变更、进度、质量)相结合

由于一个工程项目是动态变化的,有时项目经理通过监测知道项目成本正在偏离预算,但是却不知道采取什么措施来控制。在这种情况下,净现值(NPV)能够被用来作为一种持续监控的方法,因为净现值考虑了时间的因素来对未来现金流折现,它是现金流考虑时间价值影响后的结果。

4.3变化的检测和控制

Voropajev (1998)指出,施工环境的动态变化将会影响项目的实施过程、项目本身以及增加项目风险的可能性。当在开展施工活动的时候,不同于原计划的各种方法必须被应用来保持项目向前推进(根据实践经验)。因此,变化

是不可避免的,需要在项目的整个生命周期过程中管理和控制变化(Voropajev. 1998,p 16- 17)。为了确保变更程序是明确和毫不含糊的以及方便施工人员提出要求发生改变,应该建立一个有效的变更控制体系。可以从以下几个方面考虑:

a) 为确保良好的结果,应检测和预测最有可能发生变更的主要因素,应该保证变更必须由合适的人员检查

b)一旦被批准,变更应该发生并对此进行监测以检查是否按预期工作

c)项目的所有变更应该被记录在项目文件资料中(Voropajev, 1998,pl8)

5.结论

本文介绍了控制预算的最佳方法。首先,必须建立一个高效率的监管控制体系;其次,它必须包括影响成本预算目标的主要因素并将它按照重要性排序;第三,项目管理者应该结合不同的科学控制方法以达到项目的成功。

The Contractor's Role in Building Cost Reduction After

Design

Author:Waddle,Todd W.

Nationality:UK

Derivation:Cost Engineering; Feb2008, Vol. 50 Issue 2, p14-21

It has become evident from recent news articles that inflationary pressures and increased construction activity are causing many building projects to come in well over owner's budgets. This trend has increased dramatically over the past few years, as much of the construction industry has been impacted by an unprecedented increase in the cost of construction. The historical rate of increase in construction cost has been under five percent per year, as reported by the Engineering News Record. Over the last few years, the industry has seen a significant increase from historical escalation rates, up to 10-15 percent per year in many regions of the US. These increases have been caused by a variety of factors, including the following.

? Shortage of steel resulting from rapid growth in China.

? Demand for materials in the US resulting from increased hurricane damage.? Rising oil prices leading to higher manufacturing and transportation cost. ? Rising labor cost beca use of increased construction activity .

To be successful in having over budget projects awarded, the building contractor has had to take a proactive role in working with owners and design teams to reduce project cost to amounts that owners are able to award. This cost reduction is normally accomplished through the following methods.

? value engineering;

? scope reduction;

Value Engineering

Value engineering (VE) has been defined as a systematic method to improve the value of goods and services by using an examination of function.

Value, as defined, is the ratio of function to cost. Value can therefore be increased by either improving the function or reducing the cost.

It is a primary tenet of value engineering that quality not be reduced as a consequence of pursuing value improvements . VE is a process originating at General Electric Company (GE) during World War II. Because of shortages of skilled labor, raw materials, and component parts, engineers at GE

looked for acceptable alternates and often found substitutions that resulted in reduced costs and/or product improvement.

GE developed a systematic process that they called value analysis. Over the years the name gradually changed to VE. The basic steps of VE include the following:

? Information gathering: project requirements defined, function analysis.

? Alternates: various ways of meeting the requirements and functions.

? Evaluation: assessment of alternates on how well they meet requirements and costs savings.

? Presentation: selection of best alternat ives to be presented to client for decisions.

True VE evaluates life cycle costs such as initial cost, maintenance cost, operational cost, life span, time value of money, replacement cost, and frequency of replacement. VE can be undertaken at any stage of the building design process; however, it is most effective in the early stages, since it is less costly to make changes to preliminary documents .

Scope Reduction

Scope reduction involves identifying areas of the project scope of work that can be reduced in quality, quantity, or both in a manner that is acceptable to the owner.

Scope reduction items of work often consist of material or equipment substitutions that lower the cost of the project, but may not be an equal substitute. An example of quantity scope reduction would be to reduce the guttering system on a pitched roof from the entire roof perimeter to entrances only. A quality scope reduction example would be to provide vinyl composition floor tiles (VCT) in lieu of ceramic floor tiles.

After a project has been determined to be out of budget because of high bids, the project is normally either cancelled, redesigned and re-bid, or negotiations are held with the low bidder to reach an acceptable contract amount. For the building contractor that is selected for negotiations, this is an

opportunity to move toward project award and to also build a relationship of trust and openness with the owner and design team that could lead to future projects.

First, the building contractor should meet with the owner and design team to fully understand the owners project requirements, priorities, life cycle considerations, and budget.

Next, the building contractor's role is to use his estimating and construction expertise to analyze various components and systems within the project for alternate solutions. The contractor should also bring in key subcontractors and suppliers who are often able to identify alternate materials and/or systems within their specialties. Each division of work should be examined and evaluated for VE solutions. In past years, this process and service was considered part of the building contractors overhead. However, in today's market, some contractors will negotiate rates and be reimbursed for the time and effort that they spend in this process in the event that the

project is not awarded to them.

The work breakdown structure (WBS) can be a helpful tool to the building contractor in analyzing the various components and systems within a building project. The WBS is a tree-type structure of functional systems used to classify the project on a level-by-level basis . This breakdown structure facilitates the evaluation of each system of the project from the building foundations to the completed sitework.

Questions to Ask or Areas and/to Consider by WBS

This section provides a list of areas for the building contractor to examine and/or questions to ask in the WBS system level format for cost saving alternatives. Some of these changes can be accomplished

without major re-design cost and incorporated into the construction documents in the form of an addendum. Other changes listed would require extensive re-design and time delays.

—Examine interior floor finishes.

? Resilient flooring vs. ceramic or wood.

? Ceramic flooring in lieu of stone.

? Can phasing be reduced to shorten the project duration?

? Can the start of the project be timed to avoid cost impact of winter conditions?? For high-rise projects; have crane and hoisting options been compared? ? Can the Owner include the Builders Risk polic y?.

Breaking down and analyzing the components of a building project through the work breakdown structure can aid in reduction summaries also reveal that the mechanical, electrical and plumbing(MEP) systems typically offer the greatest opportunity for cost savings due to their total significance to a project. The MEP systems normally make up between 30 to 50 percent of a building project's cost.The owners of the illustrated projects accepted cost reducing changes ranging from 6 to 14 percent of the original low bids. These reductions allowed them to meet their particular budgets and have their projects constructed by incorporating the changes into addendums. Some projects may be so far over budget that substantial structural and/or building redesigns are unavoidable. However, building contractors can play a major role in bringing projects into budget—using their past experience along with their subcontractor and supplier networks to develop cost reduction alternatives that may not have been previously considered by owners and/or design teams.

Research on Competency Model:A Literature Review and Empirical Studies Abstract Western countries have applied competency models to addressing problems existed in their administrative and managerial systems since 1970s,and the findings is positine and promising. However, competency model hasn’t been introduced to China until 1990s and it is still unknown and mysterious to many Chinese managers. This paper aims to uncover the mysterious veil of competency model in order to broaden the horizon of Chinese managers and boost China's human resource development as well as management. Keywords:Competency,Competency Models,Empirical Studies of Competency Models It has been more than 30 years since competency model was utilized to human resource management.In western countries,competency model first displayed its effectiveness in government administration, meanwhile many multinationals and their branch companies applied the competency model to their daily business management and their business was a great success. As the notion of competency is gradually come to light and accepted by people all around the world,more and more enterprises have been trying to build their own competency model under the help of professional consultant firms. As a result,competency model has gradually been a very fashionable phrase in the field of management and quite a few enterprises are thus benefited from it. In recent years, competency model has become a hot spot in the Chinese academia as well as big-,middle- and small-sized enterprises alike,many relevant writings and books have also been translated and published. However, competency and competency model are still mysterious to many Chinese scholars, business managers as well as government administrators. Purpose and Significance of the Study The purpose of the study aims to make a critical literature review of the competency model,clarify some confusion related to it and explore its application. The following questions are employed to guide this study:What is competency? What is competency model? What are the theoretical and empirical findings related to competency model? The study illustrates how we could take advantage of competency model in our harmonious society building. On one hand,the study will delineate competency and competency model in order to clarify confusions related to it since it is still strange and mysterious to many Chinese managers and administrators;on the other hand,the

英语学术论文写作实践作业 作者 系(院)外国语学院 专业英语 年级2xxx级 学号 写作意向 旅游的快速发展以及随着中国融入全球化经济,中国与世界各国的交流不断增多,例如,加入WTO、2008年北京成功举办奥运会及上海世博会等,这些显示了中国在国际舞台上扮演越来越重要的角色。近些年来,越来越多的国家希望了解中国,许多外国朋友纷至沓来。特别是中国旅游风景名胜区,每年接待的外国游客越来越多。为了方便外国友人,我国旅游景区就必须提供英语景点导游词。旅游景点导游词主要指的是旅游景区公开和面对旅游者的告示、指示、提示、警示、标示等文字及图形信息,涉及到食、宿、行、游、娱、购等日常生活的方方面面。在旅游景区内,游客最为集中,与旅游宣传册、地图、宣传单等相比,景点导游词更加引人注目集中,更加直截了当地发挥其信息指示功能。由于旅游景点导游词需要及时满足的是社会公众和旅游者的直接社会、行为和心理需求,也反映了生活在这个社会群体的整体文化素质、道德修养和精神面貌,是一个国家对外交流水平和人文环境的具体体现。因此其翻译质量将会响到游客的旅游线路、兴致、感受及印象,进而间接影响我国旅游业的发展。因此,对旅游景点导游词的特点、翻译策略进行探讨具有一定的现实意义。 资料的初步整理 对于英语景点导游词,许多中外学者都做出自己的研究,提出自己的观点。以下是中外学术界的众多研究和观点。 蔡媛媛(2007)《英语景点导游词的语言特点》一文中指出,英语景点导游词具有相应的功能特点。(1)指示性。指示性景点导游词主要是提供给公众一些信息服务,没有任何限制或强制在内,同时也不强制要求公众采取任何行动,其功能只是指示服务内容。因此,指示性景点导游词也被称为指导性或引导性景点导游词。这也是景点导游词最基本、最主要的功能。例如:One Way (单行线)、Tickets (售票处)、Department Store (百货商场)。(2)提示性。提示性景点导游词提示性景点导游词提醒公众注意某些事情,同时提示性景点导游词也并不针对特殊或个别人群。这类景点导游词应用非常广泛,通过提示性景点导游词可以了解什么该做什么不该做,但是这种提示性景点导游词并不具有强制性,公众可根据实际情况来选择执行或不执行。例如:Caution!Radiation(当心射线)、Watch Your Hand(当心夹手)、Don’t Touch(请勿手扶)。(3)限制性。限制性景点导游词对有关公众提出限制或约束的要求,希望有关公众为了大众的利益遵守一定的规则。多数情况下限制性景点导游词语气较为直接,一目了然,但不会让人感到强硬、粗暴或无理。例如:Athletes Only (运动员专用通道)、Large Vehicles Keep Right (大型车靠右)。(4)强制性。强制性景点导游词对有关公众有较大约束力,要求有关公众必须或不得采取任何行动或严格遵守规则。这类景点导游词的语言直接、强制,没有任何商量的余地。例如:No Parking (禁止停车)。 上面是学者对景点导游词特点的研究,对于翻译,颜莉(2008)《英语景点导游词的文体特点及汉英翻译》一文中说到,在进行景点导游词的汉英翻译前,应先了解英语景点导游词的文体特点,这样才能更加准确地将汉语景点导游词译为地道的英语表达方式。代博君(2010)在《景点导游词的语言特征及翻译策略》一文中指出,景点导游词的翻译应属于实用翻译,也称语用翻译。法国翻译理论家Jean Delisle 将语用翻译界定为:运用语用学知识对语用文

Project Budget Monitor and Control Author:Yin Guo-li Nationality:American Derivation:Management Science and Engineering.Montreal: Mar 20, 2010 . With the marketing competitiveness growing, it is more and more critical in budget control of each project. This paper discusses that in the construction phase, how can a project manager be successful in budget control. There are many methods discussed in this paper, it reveals that to be successful, the project manager must concern all this methods. 1. INTRODUCTION The survey shows that most projects encounter cost over-runs (Williams Ackermann, Eden, 2002,pl92). According to Wright (1997)'s research, a good rule of thumb is to add a minimum of 50% to the first estimate of the budget (Gardiner and Stewart, 1998, p251). It indicates that project is very complex and full of challenge. Many unexpected issues will lead the project cost over-runs. Therefore, many technologies and methods are developed for successful monitoring and control to lead the project to success. In this article, we will discuss in the construction phase, how can a project manager to be successful budget control. 2. THE CONCEPT AND THE PURPOSE OF PROJECT CONTROL AND MONITOR Erel and Raz (2000) state that the project control cycle consists of measuring the status of the project, comparing to the plan, analysis of the deviations, and implementing any appropriate corrective actions. When a project reach the construction phase, monitor and control is critical to deliver the project success. Project monitoring exists to establish the need to take corrective action, whilst there is still time to take action. Through monitoring the activities, the project team can analyze the deviations and decide what to do and actually do it. The purpose of monitor and control is to support the implementation of corrective actions, ensure projects stay on target or get project back on target once it has gone off target。

第三方物流外文文献(原文与翻译)

我国第三方物流中存在的问题、原因及战略选择 熊卫 【摘要】我国物流业发展刚刚起步,第三方物流的理论和实践等方面都比较薄弱。本文指出我国第三方物流存在的问题在于国内外第三方物流企业差距、物流效率不高、缺乏系统性管理、物流平台构筑滞后、物流管理观念落后等。分析了产生上述问题的原因,并提出了精益物流、中小型第三方物流企业价值链联盟、大型第三方物流企业虚拟化战略等三种可供选择的第三方物流企业发展战略。 【关键词】第三方物流;精益物流战略;价值链联盟;虚拟化战略 1引言 长期以来,我国国内企业对采购、运输、仓储、代理、包装、加工、配送等环节控制能力不强,在“采购黑洞”、“物流陷井”中造成的损失浪费难以计算。因此,对第三方物流的研究,对于促进我国经济整体效益的提高有着非常重要的理论和实践意义。本文试图对我国策三方物流存在的问题及原因进行分析探讨,并提出第三方物流几种可行的战略选择。 2我国第三方物流业存在的主要问题 (一)我国策三方物流企业与国外第三方物流企业的差距较大,具体表现在以下几个方面: 1、规模经济及资本差距明显。由于国外的大型第三方物流企业从全球经营的战略出发,其规模和资本优势是毫无疑问的,尤其初创时期的我国策三方物流业,本身的规模就很小,国外巨头雄厚的资本令国内企业相形见绌。 2、我国策三方物流业企业提供的物流服务水准及质量控制远不如国外同行。当国内一些企业还在把物流理解成“卡车加仓库“的时候,国外的物流企业早已完成了一系列标准化的改造。同时,国外的物流组织能力非常强大,例如德国一家第三方物流公司,公司各方面的物流专家遍布欧洲各地。如果有客户的货物需要经达不同的国家,那么欧洲各地的这些专家就在网上设计出一个最佳的物流解决方案。这种提供解决方案的能力就是这第三方物流公司的核心能力,而不像国内公司号称拥有多少条船,多少辆车。 3、我国加入WTO后物流产业的门槛降低。在物流服务业方面:我国承诺所有的服务行业,在经过合理过渡期后,取消大部分外国股权限制,不限制外国服务供应商进入

第一篇: 航空博物馆与航空展示公园 巴特罗米耶杰·基谢列夫斯基 飞翔的概念、场所的精神、老机场的建筑---克拉科夫新航空博物馆理性地吸取了这些元素,并将它们整合到一座建筑当中。Rakowice-Czyzyny机场之前的旧飞机修理库为新建筑的平面和高度设定了模数比例。在此基本形态上进一步发展,如同裁切和折叠一架纸飞机,生成了一座巨大的建筑。其三角形机翼是由混凝土制成,却如同风动螺旋桨一样轻盈。这个机翼宽大通透,向各个方向开敞。它们的形态与组织都是依据内部功能来设计的。机翼部分为3个不平衡的平面,使内外景观在不断变化中形成空间的延续性,并且联系了建筑内的视觉焦点和室外的展览区。 新航空展示公园的设计连接了博物馆的8栋建筑和户外展览区,并与历史体验建立联系。从前的视觉轴线与通道得到尊重,旧的道路得到了完善,朝向飞机场和跑道的空间被限定出来。每栋建筑展示了一个主题或是一段飞行史。建筑周围伸展出巨大的平台,为特殊主题的室外展览提供了空间。博物馆容纳了超过150架飞机、引擎、飞行复制品、成套的技术档案和历史图片。这里的特色收藏是飞机起源开始的各种飞行器,如Jatho1903、Grade1909、莱特兄弟1909年的飞机模型和1911年的鸽式单翼机。 The first passage: Museum for aviation and aviation exhibition park Bartiomiej Kislelewski The idea of flying, the spirit of place, the structure of the historic airfield – the new Museum of Aviation in Krakow takes up these references intellectually and synthesizes them into a building. The old hangars of the former airport Rakowice Czyzyny set the modular scale for the footprint and the height of the new building. Developed from this basic shape, as if cut out and folded like a paper airplane, a large structure has been generated, with triangular wings made of concrete and yet as light as a wind-vane propeller. The wings are generously glazed and open in all directions. Their form and arrangement depend on the interior uses. In the floor plans of the wings, the three offset
