1、原文： Assessment of cost control systems The most important function that facilitates construction organizations to accomplish profit maximization is cost control. However, the absence of a well established cost control system has caused failures to many Thai contractors especially during the curren

2、t economic recession period. To comprehensively understand cost control systems in practice, this study theoretically assessed effectiveness as well as the deficiencies of the 'traditional' systems the 'effective' systems. In addition, by contrasting what are found in 'effective' systems but not fou

3、nd in 'traditional' systems, critical attributes most contributing to the systems' successfulness were identified so that the improvement steps can be suitably prioritized. The validated findings indicated remarkable contrasts between 'traditional' and 'effective' systems. Two critical aspects, incl

4、uding advancement of cost control framework and systematic participation of site personnel in cost control, were found to be the major differences. Interestingly, similar conditions were encountered in various countries such as Greece, Pakistan and Australia; hence suggestions from this study could

5、be internationally useful. In actuality, contractors perceive cost control as a pre-requisite factor towards profit maximization. An unprecedented growth in the Thai construction industry since the late 1980s had rotated the market to be the contractors' in which high profit margin could be facilel

6、y accommodated in bid quotation. A roll of forthcoming projects continually offered and contracted without intermission thus allowed contractors to luxuriate in advanced payment and credit from suppliers. This healthy cash flow situation, unfortunately, could be predominant over real profit material

7、ization. Actual symptoms of unsystematic cost control in most Thai construction companies have been concealed until apparent recession of the economy in 1997. Severe declination of the Thai GDP and construction growth rates shown has given rise to business failures in many organizations. Equally wor

8、se, for the others surviving, extremity of nightmares in the ultimately low-demand market is still unpredictable. Cost control system Despite extensive literatures reviewed in cost control, an integrated view of the system was not portrayed. The system functions were mostly discussed in isolated

9、 fashion, for instance, estimating budgeting, monitoring and analysing, and reporting. Furthermore, most previous research works concentrated more on theoretical concepts rather than operation in the real-complicated environment. Applying a synergetic approach, the integrated view of the cost contr

10、ol system is proposed to enhance value of past efforts. As a main framework, the cost control system in this paper is defined as a kind of information system that aims to provide management with timely and accurate cost information so that timely proper corrective actions can be taken. In addition,

11、management information can be stored in a historical database and, in turn, serves as a feedback for future estimation. The system consists of three main parts, namely, cost control framework, cost control functions and management information. To solidify a specific set of objectives, a pre-survey

12、of existing cost control systems in Thai large-scale construction organizations was primarily conducted. A contact list of the top 100 organizations in terms of turnover was achieved through collaboration with the Thai Contractors Association (TCA). Each contract ever handled by these organizations

13、covers a project area equivalent to over 30000 or has approximate value of more than 100 million Baht (3 million $US). Introductory letters were sent to the top 100 contractors requesting assistance on the preliminary survey of their cost control systems. Telephone interviews were followed up. Two f

14、ocal points regarding the recent development of cost control system and the system's ability to indicate the on-going cost status of each work item were investigated. The result elaborated indicated that the cost control systems in most organizations have not been changed much from the past. Out of

15、 100 organizations, only five have initiated a development plan and only two of them have successfully implemented their cost control systems. Based upon this finding, two types of the system can be categorized. First, the 'traditional' system, commonly found in most organizations, is the system tha

16、t has never been seriously developed and implemented. Secondly, the 'effective' system is the system that has been seriously and continuously improved until management information that facilitates decision making for timely and proper corrective actions as well as estimating process in future projec

17、ts can be obtained. This type of system, unfortunately, is exceptionally found in a few organizations. Objectives To achieve better understanding of how the existing systems in real practices are being operated and thereby formulate focal aspects for improvement, the specific objectives of this pa

18、per were to: ? Conduct a comparative assessment between 'traditional' and 'effective' cost control systems in accordance with the integrated system view including cost control framework, cost control functions and management information. ? Identify critical attributes that most contribute to the s

19、ystem successfulness by contrasting what are found in 'effective' systems but not found in 'traditional' systems. Methodology Qualitative research, particularly 'case study', that persuades through rich depiction and strategic comparison across cases (Firestone, 1987), was chosen as the key method

20、ology in this study. For cases sampling, the 'theory based' and 'typical case' strategies proposed by KUZEL (1992) and Patton (1980) was ground for selecting the cases of 'effective' and 'traditional' cost control systems, respectively. Besides, the 'multiple case' strategy (Yin, 1991) that can add

21、confidence to findings was also applied. Because of the classified nature of cost information, most organizations, unfortunately, were reluctant to allow researchers an in-depth investigation. Two organizations that qualified as 'traditional' systems were volunteers and the two organizations that qu

22、alified as 'effective' systems were persuaded to participate in the assessment. The profiles of the sampled organizations are shown in Table 2. It should be noted that the names of the cases have been changed by randomly assigned the sequence A, B, C, D for confidentiality and unbiased analysis. Me

23、asure identification and system assessment Based on the integrated view of the cost control system shown in, this section selectively elaborates substantial aspects and essence of each component, thereby identifying measures that enable system evaluation. To maintain continuity, comparative discuss

24、ion of the assessed results among the four cases is also presented. This section consists of two main parts including (1) cost control framework, and (2) cost control functions and management information. Cost control framework This part consists of three substantial factors, namely Work Breakdown

25、 Structure (WBS), Cost Code and Earned Value Concept. The essence of these factors was widely discussed by many researchers. It is well accepted that these factors must be appropriately employed as a critical frame for cost control system. With well-established framework, management can systematical

26、ly manage the project in small manageable fashion and will not be overwhelmed by information explosion during construction phase. A pattern of proper cost control framework is illustrated Work breakdown structure A task-oriented family tree of activities widely known as WBS is indispensable for p

27、roject cost control. Unemployment or improper design of this structure can cause a chain of deficiencies in all cost control functions. Commencing with estimating and budgeting, work items may be duplicated, overlooked, or shelter inadequate details. This ineffective control reference, therefore, ca

28、nnot be served as a guideline for systematic monitoring as well as comprehensive analysing. Finally, an evaluation of project outcome and establishment of historical cost data can also be ineffective. Systematic structure The project must be partitioned into manageable elements of work for which

29、budgets and expenditures can be systematically controlled. Formation of the WBS must begin by subdividing, or partitioning the project objective into successively smaller work elements until the lowest level to be reported on or controlled is reached. Compliance with accounting code When an accoun

30、ting system is integrated within the cost control system, not only data processing can be substantially speeded up but also many frauds can be avoided. For instance, the account payable checking system can directly verify whether invoices of each work item are still under-budget and should be paid o

31、r not. Furthermore, account reports generated at head office and job cost reports generated at site can be crosschecked for ensuring accuracy. Cost status If the company employs the earned value concept, cost status at a given progress can be identified. The cost status can be defined as Cost stat

32、us = earned value — total actual expenditure used to accomplish a given earned progress; when (Positive value = underrun, negative value = overrun), and Earned value = budget unit price x actual quantity in place By identifying the cost status, management gains an insight on whether and how much, at

33、 a given progress, the total actual expenditure of each item has been over or under the established budget. At a given progress, the cost status can be identified before the finishing of the work item so that timely proper corrective actions can be taken before being too late. Significantly, an effe

34、ctive report format should contain both: (1) comparison among actual quantity in place or percent progress, budget and total actual expenditure that is used to accomplish the earned progress, and (2) calculated earned value and cost status. Cost control functions Referring to the previous part,

35、the assessment of the control framework probably enables the author to summarize effectiveness as well as deficiencies of each audited system. However, to acquire more confidence and a richer picture, assessment of each control function has to be taken into account. Subjected to research constraints

36、, efforts spent in this section did not try to cope with all excessive detail in real practices, yet it valuably covers all critical aspects. This part broke down into seven sub-sections consisting of one supported function estimating and six functions for cost control budgeting, monitoring, analys

37、ing, reporting, corrective action, and post-evaluating. The cost control function breakdown structure shown illustrates major components in each function. Advancement of cost control framework The results indicated that control framework applied in the 'effective' system incorporated more advanced

38、 theoretical framework than the 'ineffective' system. Three critical advancements were found to be successful contributions for effective system functions. First, one integrated control frame (WBS and CBS) sheltering adequate level of detail facilitates monitoring of actual expenditures of each work

39、 item in terms of activity progress. Secondly, incorporated with application of the earned value concept, cost status can be identified before finishing of each work item, thus allowing timely and proper corrective actions. Thirdly, the integration of an accounting system within the cost control sys

40、tem not only substantially synchronizes on-site and head office data transferring but also ensures accuracy and consistency of the control mechanism. Systematic participation of site personnel in cost control Another critical difference between 'effective' and 'ineffective' systems is systematic p

41、articipation of site personnel in cost control. The 'effective' system involving participation of project manager (site) in the decision for budget allocation enables in achieving a realistic budget and transferring the goals of the company to on-site management. Then, clarity of site responsibiliti

42、es in monitoring, analysing and reporting the cost status do motivate site personnel to consciously exercise corrective actions on daily basis. In view of the whole system, the results of the case studies clearly showed that both organizations with 'ineffective' control framework also do not encour

43、age the site participation programme. Practically, the head office does not let site personnel know the budget and assigns them control only in terms of quantity. For cost monitoring, analysing and reporting, the responsibility is taken by accountants who can generate information based on bills and

44、invoices. As a result, the generated cost information cannot reflect the real on-site situation and cannot provide great benefits to management to take proper and timely corrective actions. On the other hand, the others with 'effective' control framework also have systematic participation of site pe

45、rsonnel in cost control, which undoubtedly contributes to the goal achievement. To improve the 'ineffective' system, the first appropriate pace would fall in advancing the cost control framework. After this advancement is significantly improved, the concentration can be switched to the systematic pa

46、rticipation of site personnel in cost control so that a more effective system can be achieved. Although this study has focused on cost control practices in Thailand, a developed theoretical assessment framework would be of use to the international community. In addition, common practices have been

47、interestingly found in various countries. Earned value concept has not been applied in Greek construction organizations. Pakistani construction companies collect feedback data only through monthly cost bills. The lack of any truly site-based control system was significantly found in Australia. It is

48、 apparent that conditions in these countries are still very much near the Thai, therefore, the suggestions of this study would be widely applicable. However, to confidently generalize these findings, more case studies in different countries need to be undertaken. Source:Reinhardt,.“Engineerin

52、該系統(tǒng)重要由三個(gè)重要部分構(gòu)成，即成本控制框架、成本控制功能和管理信息。 鞏固一套特定旳目旳，在泰國(guó)一種大型施工組織調(diào)查既有旳成本控制系統(tǒng)旳活動(dòng)。一種100強(qiáng)旳組織按照合伙獲得旳成交量是泰國(guó)承包工程商會(huì)。每一份合約曾經(jīng)由這些組織涵蓋了工程占地面積相稱于超過(guò)30萬(wàn)平方米或有大概值超過(guò)100萬(wàn)泰銖（300萬(wàn)美元）。簡(jiǎn)介信件被寄給百?gòu)?qiáng)承包商祈求協(xié)助初步調(diào)查其成本控制系統(tǒng)。電話面試進(jìn)行隨訪。兩個(gè)重點(diǎn)對(duì)近年來(lái)發(fā)展旳成本控制系統(tǒng)和系統(tǒng)旳能力成本狀態(tài)顯示項(xiàng)目旳各項(xiàng)工作中應(yīng)注意旳問(wèn)題。 成果表白，論述了成本控制系統(tǒng)在過(guò)去旳大多數(shù)組織中都沒(méi)有太多變化。在一百個(gè)組織中，只有五個(gè)已經(jīng)發(fā)動(dòng)一場(chǎng)發(fā)展籌劃，她們當(dāng)中只有

60、分派控制只在數(shù)量上。出于成本旳監(jiān)測(cè)，分析和報(bào)告，由會(huì)計(jì)師旳責(zé)任是采用誰(shuí)可以生成信息基本上旳帳單和發(fā)票。因此，生成旳成本信息不能真實(shí)反映現(xiàn)場(chǎng)旳狀況，不能提供巨大旳利益，管理要采用合適和及時(shí)旳糾正措施。另一方面，“有效”控制框架旳其她人也有系統(tǒng)旳成本控制，這無(wú)疑有助于實(shí)現(xiàn)目旳旳現(xiàn)場(chǎng)工作人員旳參與。為了改善“無(wú)效”系統(tǒng)，第一種合適旳步伐將推動(dòng)成本控制旳框架。在此之后旳進(jìn)步是顯著提高旳，可以切換到現(xiàn)場(chǎng)人員在成本控制系統(tǒng)旳參與，使一種更有效旳機(jī)制得以實(shí)現(xiàn)。 雖然這項(xiàng)研究集中于在泰國(guó)旳成本控制實(shí)踐，發(fā)達(dá)旳理論評(píng)估框架將使用于國(guó)際社會(huì)。此外，常用旳行為在世界各國(guó)已有趣旳發(fā)現(xiàn)。掙值旳概念尚未應(yīng)用于希臘旳建設(shè)公司。巴基斯坦建筑公司收取旳每月費(fèi)用只有通過(guò)法案反饋數(shù)據(jù)。在澳大利亞發(fā)現(xiàn)對(duì)任何一種真正旳網(wǎng)站為基本旳控制系統(tǒng)明顯缺少。很明顯，這些國(guó)家旳狀況仍然非常接近泰國(guó)，因此，本研究旳建議將得到廣泛應(yīng)用。但是，要自信地概括這些調(diào)查成果，在不同旳國(guó)家需要更多旳個(gè)案進(jìn)行研究。 出處：萊因哈特，《評(píng)估成本控制系統(tǒng)》，工程、建筑與建筑管理，（8）：368-380.
