Selection a contractor in e-tendering procurement of goods and service is an routine activity at tenders of Central Kalimantan government. It task is doing the selection against the contractors of e-tendering that offer documents are uploaded on the website of the official Bureau of procurement of goods and services of Central Kalimantan. Selection a contractor is a complicated task because it must be transparently but the problem is the system still lacks proper judgment for not explained about score points for contractors who do not win. System use fall system and not give a thorough explanation about contractors who did not win the tender. This research aims to be able to resolve the problem using Analysis Network Process to select contractor to provide the weight of each of the criteria. The criteria are administrative, price, technical, and prove the qualifications must be completed by each participant contractor who register on e-tendering. The contributin this research serve as a guide for the Bureau of procurement of goods and services and select the contractor in tenders held so a clear assessment and is open to contractors who follow e-tendering held Bureau Procurement of goods and services in Central Kalimantan.

Construction and investment projects inherent risks in an extremely wide range of human activity fields. An analysis of risks from the viewpoint of management and mitigation is conducted in this article. Particular attention is paid to the analysis of risk events related to the choice of an unqualified contractors performing the job. The compliance of duration implementation project, the budget amount, and the quality of performed work depend on this choice. The contractors risk assessment methods analysis showed that besides the overall criterion for all methods connected to the cost of work it is vital to take into account the qualifications, reputation, material and technical base of a contractor, the time and quality of the work performed previously. Existing methods with criteria of the choice of contractors performing the job are considered. The universal methodology with a set of criteria that satisfies all construction process participants, and based on publicly accessible information about companies and their experience is essential.

The South African government has been implementing various small and medium sized contractor development programmes in an effort to redress the legacy created by apartheid government. The programmes fulfil such an objective through awarding construction projects to the historically disadvantaged Black contractors to enable them develop competent skills, build viable construction firms, create jobs and redistribute wealth. A mentorship programme was put in place to assist the contractors with technical, managerial, contractual and business impediments they might be encountered in the project execution and in running the construction business. The main aim of the paper was to conduct an evaluation of the contractor development mentorship programme in South Africa using the Free State Province as a case study. Questionnaires were distributed to 120 small and medium contractors in the Free State Province, and a review of literature was undertaken. Financial factors were found to be amongst the leading causes of contractors’ failures. It was also established that educational qualification and experience in the construction industry have an effect in a contractor’s failure or success. A lot of contractors revealed that they were not exposed to the Contractor Development Programmes like in other provinces hence 74% did not participate in any contractor development programmes and only 26% did participate. The paper concluded with recommendations on how mentorship within the contractor development programme can be improved.

Full textAbstract:
Project management is the overall planning, coordination, and control of a project from beginning to completion. Project management is aimed at meeting a clients requirement in order to produce a functionally and financially viable project. Project management is project management that applies to the construction sector. The construction industry is composed of five sectors: residential, commercial, civil, industrial, and environmental. A construction manager holds the same responsibilities and completes the same processes in each sector. All that separates a construction manager in one sector from one in another is the knowledge of the construction site. This may include different types of equipment, materials, subcontractors, and possibly locations. A contractor is assigned to a construction project once the design has been completed by the architect or is still in progress. This is done by going through a bidding process with different contractors. The contractor is selected by using one of the three selection methods: low-bid selection, best-value selection, or qualifications-based selection. A construction manager should have the ability to handle public safety, time management, decision making, mathematics, and human resources.

The number of contractor companies, especially in the field of roads every year continues to increase. Based on data obtained from LPJK website (Construction Services Development Agency) Province of Aceh Year 2016, shows that from 2,717 road contractors in Aceh Province, 1% of them are big qualification, 10% middle qualification and 89% small qualification. The problem is from the increasing number of road contractor companies in Aceh Province, it has not been followed by an increase in qualification and performance. These improvements can be seen from the quality of work, the timeliness of completion of implementation, and the efficiency of resource utilization of personnel, capital, and technology. This study aims to analyze the relationship and influence between contractor's qualification factors on the quality of road construction project, and to know the dominant factor in contractor company's qualification affecting the quality of road construction project in Banda Aceh City. This study used qualitative and quantitative methods through questionnaires, where the respondents were addressed to 90 road contractor companies. The contractor company has implemented projects from 2010-2016, with funding sources from APBA. The independent variables reviewed are contractor qualification factors consisting of legal factors, technical factors, and administrative factors, while the dependent variable is the quality of road construction projects. The results show that the legal, technical and administrative factors all have a very high relationship to the quality of road construction projects in Banda Aceh City. The contractor's qualifying factors all have a significant effect on the quality of road construction projects in Kota Banda Aceh of 91.6%. The dominant factor in the qualification of contractor companies affecting the quality of road construction projects in Banda Aceh is the technical factor. This suggests that when engineering factors are improved by contractors, the quality of road construction projects will increase.

Full textAbstract:
The findings of a recent study on the procurement of professional architectural and engineering (A/E) services in New York City are outlined in an attempt to evaluate some of the claims put forward by proponents and opponents of qualifications-based selection (QBS) of such services. QBS is a federally mandated requirement enacted by the U.S. Congress in 1972, in recognition of the need for improvements in the way in which professional A/E services are procured. The law, commonly referred to as the "Brooks Act," requires that architects and engineers be selected on the basis of their professional qualifications and subject to negotiation of a fair and reasonable compensation of such services. New York State is one of the states that adopted QBS (a total of 41 states had adopted it as of the end of 2001); but the New York State law does not cover local jurisdictions, and New York City continues to use competitive pricing as its primary method of selecting A/E contractors, citing the numerous advantages of the current system as well as the disadvantages of the proposed QBS method. The present study was based on past literature as well as recently procured projects in New York City (1997 to 1999), as presented by the New York City Mayor’s Office of Contracts during a public hearing on QBS (December 1999).

Purpose The Indonesian construction industry has to considerably rise due to the issues of quality product, organisational performance and global competitiveness faced today, along with settling several national challenges that continue to plague the construction industry. Delivering high-quality construction products and services is non-negotiable when competing for contracts with international constructors. Developing such an assessment system to evaluate the performance of Indonesian construction companies is an urgent need in order to encourage and motivate the construction companies to continually improve their performance in the execution of construction works. The purpose of this paper is to empirically test the key attributes related to the evaluation of quality and performance in the construction project-based case of Indonesia. Design/methodology/approach A survey was conducted in the five provinces in Indonesia involving 216 construction practitioners from medium and large qualifications of construction companies. Findings On the basis of the data analysis results, the study develops the 39 key attributes that can be a basis for the development of Indonesian building construction project performance assessment system. The attributes cover construction companies’ performance during project implementation, in delivering final project results and in implementing quality procedures for building construction works. Originality/value The outcome of this study is considered significant to provide a tool for the government to assess the quality performance of contractors in delivering projects against specified standards, and a guideline for the contractors to improve their competitiveness by implementing continuous quality improvement. The confirmed attributes developed from this study is an initial step towards developing an Indonesian construction comprehensive quality performance assessment system.

The article is devoted to the assessment of the contractor companies activity in the field of safety both before the start of work execution and during the execution of work at the construction site of the Client’s company. Analysis is given concerning the industrial injuries from 2009 to 2018 in Russia, based on which the tendency to reduce industrial injuries for the current period is determined, and the coefficients of the frequency of injuries in various countries for 2015 are calculated. Based on the performed analysis, the injury rate in Russia is still at a high level. Economic component for the materials, personnel qualifications, and savings on safety from the Client’s company can also lead to injuries at the construction site. The main reasons for low quality of the work performed at the construction site, which in turn lead to injuries, are given in the article. Matrix for the assessment of the contractor companies was developed, with the help of which it is proposed to assess all the aspects of their activities that effect on safety of the work performed. Among the assessed aspects there are sections related to training, behavior and motivation of the personnel, audits conducted by the contractor companies in relation to the subcontractors, investigation of incidents by using the current procedures and contractor personnel responsibilities. One of the matrix elements is presented for assessment. Each element from the given section is proposed to be assessed on a scale from 0 to 3, where each aspect is presented in the form of an action, an assessment of this action and its result. Recommendations on the use of this methodology in the selection of contractors are provided.

Full textAbstract:
This paper presents results of a study to assess the Government Contractor Classification System in Saudi Arabia. Contract award procedures in public projects of Saudi Arabia are accomplished in two steps. The first one involves qualifying contractors to insure that their technical, financial, and managerial capabilities are suitable for the project to be awarded. This qualification is accomplished by the Contractor Classification Agency- Ministry of Municipal and Rural Affairs- in which the contractor is classified according to his specialty and capabilities. In the second step, bids of the contractors who satisfy the required classification are evaluated to select the best bid. Since the contractor classification is the only screening method to disqualify incompetent contractors and the difficulty of dismissing a qualified contractor who submits the lowest bid, the contractor classification must be an actual measure for the contractor's capabilities. To assess the contractor classification system a questionnaire has been prepared and distributed to the project mangers in different public ministries and agencies. The number of distributed questionnaire was 250 and 198 were collected and used in this study. In order to conduct an objective evaluation, a comparison has been conducted between performance of contractors who are awarded projects based on the contractor classification only with performance of contractors who are awarded projects based on the contractor classification and an additional prequalification by the project owner. Also, Chi-squared test was used to verify the cause of the difference in results of using these two types of prequalification. Results of the study reveal that the contractor classification system does not properly reflect the contractors’ capabilities.

Purpose The selection of a suitable contractor for a project has a significant impact on project success. In order to avoid the selection of an incapable contractor, the capabilities of contractors must be assessed prior to tendering through pre-qualification. However, the pre-qualification process is characterized by partiality and ambiguity. In view of this, numerous models have been developed to solve the pre-qualification problems. Prior to the development of such models, it is very important to assess how the pre-qualification criteria impact project success criteria so as to aid in the selection of pre-qualification criteria while considering the project and client’s objectives. Therefore, the purpose of this paper is to ascertain the relationship between contractors’ pre-qualification criteria and project success criteria. Design/methodology/approach The study utilized explanatory research design in testing 35 hypotheses. The views of 121 practising quantity surveyors were solicited using a structured questionnaire and analyzed using the partial least square structural equation modeling to validate the hypothesis. Findings In all, 13 of the 35 hypotheses were not supported. The findings indicated a clear relationship between contractors’ pre-qualification and project success. Practical implications Therefore, it is evident that the practice of lowest evaluate bidder is not adequate for providing a satisfactory project outcome. It is, therefore, suggested that more emphasis should be placed on contractor’s technical abilities, health and safety and management capabilities as they have proven to have a significant correlation with the project success. Originality/value This study provides insights to the how various pre-qualification criteria can impact the project success criteria and further contributes to the symbiotic that exist in the literature on pre-qualification and project success.

Selecting a construction contractor is a major decision which may influence the progress and success of any construction project. The paper analyses criteria used to evaluate qualification of contractors in Lithuania and abroad. Both in Lithuania and abroad, the bid price of construction works is the main criterion for evaluation of con‐tractors. The lowest price often cannot guarantee commitments on quality and duration of a construction project. Therefore, when selecting a contractor, a client must not only compare bid prices but also set other criteria for evalua‐tion of qualification and determine their weight. A contractor must be selected according to both quantitative and qualitative criteria, and bids should be compared. Only on the basis of quantitative and qualitative evaluation criteria and by comparing bids of contractors it is possible to select a qualified, competent and reliable contractor, to evaluate its qualification, economic and financial condition and technical capability and skills and to achieve relevant results in a construction project. The paper provides an investigation of Lithuanian companies, which analyses issues related to evaluation of contractors’ qualification. The paper is completed with a discussion of the investigation results and delivery of proposals based on expert estimations of the weight of criteria for evaluation of contractors.

Purpose – It is important to recruit site supervisors with the right attributes as they play an important role in raising construction productivity and improving project outcomes. The purpose of this paper is to investigate the association between a site supervisor’s attributes and project outcomes. The specific objectives are to: identify the attributes of site supervisors that are significantly correlated with project outcomes (cost, time, quality and client satisfaction); examine whether site supervisors with different educational levels and job experience have different attributes; and recommend the attributes to be considered when selecting site supervisors. Design/methodology/approach – A questionnaire was designed based on the attributes identified from the literature review. The sampling frame was Singapore-based construction site supervisors. The data collected were analysed using the Statistical Package for the Social Sciences software. Findings – The results show that site supervisors who have IT skills are also likely to have projects that have good time, quality and satisfaction outcomes. In addition, the projects of supervisors with longer work experience show significantly better time performance and higher client satisfaction. Research limitations/implications – The limitations include low response rate, and the subjective nature of a Likert scale which was used to rate the attributes of site supervisors. While the importance of hard and soft skills is known, the contribution to knowledge is that this study showed the important role that educational qualifications play in site supervisors’ performance and their soft skills. Practical implications – It is recommended that contractors employ site supervisors who have at least a construction diploma, have IT skills and possess job experience in order to optimise their project outcomes. Originality/value – The study revealed that certain demographic characteristics of site supervisors (i.e. length of work experience and educational qualifications) have significant impact on project outcomes. Site supervisors with higher educational qualifications and more job experience also have better soft skills.

Full textAbstract:
Historically the selection of contractors in North America was almost exclusively based on the lowest tendered price. Owners utilized competitive tendering for its simplicity and fairness in the award process. More recently, owners have reconsidered the use of low price as the basis for selecting contractors and therefore have attempted to modify the traditional low bid system with qualification and evaluation clauses. Qualification and evaluation clauses have caused considerable controversy in the public sector, where contractors are concerned about the legitimacy of tendering procedures when public funds are used. Although contractors agree that the system needs improvement, there are conflicting views on what should be done. This paper provides a summary of traditional tendering procedures and illustrates two possible modifications to the contractor selection process. The intended audience is practicing professionals, particularly those in the public sector where the objectivity of the tendering process is under such scrutiny. Evaluation is selected as the direction with the most potential for improvements. The evaluation option is analyzed by examining its legal implications through a discussion of recent case law. Finally, recommendations for implementing an evaluation system are discussed to address the issues identified through the legal discussion and from the opposing views in the construction industry. Key words: construction, contract law, competitive bidding, contractor qualification, bid evaluation.

AbstractContractors, among other construction stakeholders, are vital in achieving the set goals of a project. Adequately engaging a capable contractor is an important task for a client. This study aims at determining the reasons for clients contending with contractors that are not committed to health and safety (H&S). The study was conducted through a literature review, a questionnaire was developed and distributed to 286 construction stakeholders in the Nigerian construction industry. Cronbach alpha was used to test the reliability of the questionnaire used for data collection. Mean scores (MSs) were adopted to determine the major factors that influence clients’ selections and factor analysis was used to cluster variables of high inter-correlations. Findings from the survey reveal that H&S is not a clients’ goal or a project value hence, H&S is not viewed as a vital pre-qualification criterion for contractor selection. This results in a poor checklist concerning contractors’ quality assurance and inadequate verification of contractors’ H&S history. Therefore, appointing non-compliant H&S contractors. The findings provide information on the influence clients have respecting H&S as a prequalification criterion and towards construction workers’ H&S. This will enable construction stakeholders to make the right decision in the pre-qualification of contractors.

Introduction: The coal mining company is a company that plays an important role in the Indonesia’ economy, but it is one of the high potential risk industry because most of its activities are carried out by contractors who generally undisciplined and have a lack understanding of Occupational Safety and Health. To solve this problem, the Contractor Safety Management System (CSMS) program must be conducted. The purpose of this study was to determine the implementation of CSMS program in a coal mining company in Indonesia. Methods: This cross-sectional study was conducted at a coal mining company in South Kalimantan in 2017 and analyzed descriptively. The CSMS stages and its program were obtained by direct observation using checklist sheets and study documents. Results: The CSMS procedure at the coal mining company started with risk assessment, pre-qualification, qualification, pre-work, monitoring and evaluation activities. To increase the effectiveness of the OSH program, the coal mining company also conducted additional activities such as supervisor competency training, general morning talk, technology guidance, audits and occupational safety health as well as environment seminars. Work accidents rate at three main contractors in the coal mining company was effectively reduced after an audit and improvement of the implementation of CSMS in 2016. Conclusion: CSMS activities in coal mining company have been carried out routinely and systematically where monitoring activities are carried out by coal mining company’s and sub/contractors’s QHSE officer, and the implementation of CSMS that is consistent and fit to the standards in 2016 proven to reduce the work accident rates in the coal mining company.

Full textAbstract:
To overcome the disadvantages of the low bid price policy in open competitive contracts, many are advocating the average bid method for bid evaluation. However, as elucidated in this study, this method has some disadvantages. The purpose of this paper is to propose an alternate statistical procedure for bid evaluation. Such procedure applies simple statistical analysis to identify unrealistically low-priced bids, based on either the t-distribution or the normal distribution of a previously established database of similar bids. In this procedure, the ratio of a contractor's bid to owner cost estimate is used to eliminate the distorting effect of the project size. The unrealistically low-priced contracts are then excluded and the bid with the lowest price among the remaining bids is accepted. The procedure requires establishing a database of previous bids.Key words: bid evaluation, competitive bidding, contractor qualification, tender evaluation, contract administration, contract management, bid management.

Full textAbstract:
This paper deals with the efforts and results of a Management driven campaign to improve contractor safety performance in WAPET's operations.WAPET Management identified Contractor safety performance as one of four key safety focus areas in their 1995 Business Plan. The other focus areas were Hazard Analysis, Training and Audit and Review.Strategies adopted for achieving improvements in contractor safety included:aligning Contractor Goals and Objectives with WAPET's by involving major contractors in 'Best Practices' workshops. The workshops specifically addressed the Business Plan focus areas and the identification and measurement of performance indicators. The workshops provided contractors with an open forum to express their views and efforts in these areas;holding follow-up meetings with individual contractors and contractor groups with common areas of work. Both contractors and WAPET management detailed the status and efforts being put into these areas. These meetings identified improvement opportunities and opened up communication links both with WAPET personnel and between contractors; andimplementing the results of the workshop and meetings by upgrading WAPET's Safety Management System particularly in the areas of pre-qualification, contracting philosophies and contractor management philosophies.Feedback on each stage of the 1995 program was used to determine the strategies for the 1996 program. The workshops and meetings highlighted process improvement opportunities particularly in areas of industry standardisation, development of contractor Safety Management Systems, lines of communication/accountability, employee involvement and performance indicators. These opportunities were documented in a 'Contractor Best Practice* manual of which over 350 have been distributed.Conventional safety measures indicate a 50 per cent improvement in both LTI and Total Reportable frequency rates for WAPET's contractors in the past 12 months. The success of the program was also demonstrated by other indicators such as greater openness in communications, greater participation in safety meetings and a closer working relationship with WAPET.

Purpose The studies on contractor prequalification focus more on the review of models and algorithms rather than review of the criteria for contractor prequalification. However, the basis of every prequalification model primarily relates to the measurement and judgement of prospective contractors based on a set of decision criteria. This paper aims to address the gap by reviewing academic papers on contractor prequalification criteria. Design/methodology/approach A desktop search was conducted under the “T/A/K (title/abstract/keyword)” field of the Scopus search engine. A total of 49 papers were initially identified; however, only peer reviewed journals were selected for the study; therefore, a sample of 36 was subsequently used. Further filtering was done in which 26 papers were found valid for further analysis as it was realized that, not all the identified papers presented empirical arguments about the issue of contractor pre-qualification criteria. The selected 26 papers were subjected to content analysis to identify the key contractor pre-qualification criteria. Findings A total of 41 criteria were identified which were subsequently classified into six main categories, namely, technical considerations, management considerations, financial considerations, reputation considerations, general experience considerations and health, safety and environmental considerations. There was an indication that, the involvement of health, safety and environmental considerations in contractor prequalification proceedings is limited. Research limitations/implications The major limitation of this research was the limited number of papers selected for further analysis based on the Scopus search engine. The identified criteria serve as a basis for further empirical studies on contractor prequalification criteria. Practical implications The outcome of this study broadens the understanding of practitioners and researchers on the various criteria for contractor prequalification. Originality/value By critically reviewing available literature on contractor prequalification, the study sets the tone for further empirical studies on contractor prequalification.

Full textAbstract:
Nowadays, clients are the dominant groups in almost all types of industries. However, the construction industry is unique and consultants, as representatives of clients, are very important figures in this industry as well. By presenting survey findings of 91 clients and 50 consultants, this study reveals clients’ and consultants’ differing expectations of contracting organisations during contractor qualification and selection. The study has clearly confirmed the fact that consultants’ perspectives are rather different and their contractors’ expectations of their clients vary very significantly from the clients themselves. Furthermore, significantly different results were found even among different types of consultants and different categories of clients. Moreover, this study showed that both clients and consultants had high willingness to continue working with the same contractor in possible future works assuming they are satisfied with the previous works. The criteria, which contribute to achieving full client and/or consultant satisfaction and hence lead to possible repetitive works are identified and the results showed the existence of significant difference between clients and consultants perspectives regarding this issue as well. The framework presented within this paper aims to help the contracting organisations to compare and recognise the different approaches and perceptions of both clients and consultants during contractor qualification and selection processes. The contracting organisations in the related sectors will be able to use the framework provided within this study to recognise the overall demand in a more complete and better manner and hence formulate or modify strategies accordingly.

Full textAbstract:
The main goal of the public procurement reform in Russia was to limit corruption. The government prohibited the most part of qualification criteria in the selection process and used open auctions as the main tool of contract placement. However simplification of procurement procedures led to opportunism on the side of suppliers. In this paper using the unique dataset of 2000 contracts executed in 2008-2010 for a large public customer we define the factors explaining the risk of suppliers non-performance. Econometric analysis showed that under current procurement regulation in Russia the risks of suppliers non-performance are higher for large contracts, contracts executed in October-December and contracts placed at open auctions. However contrary to anecdotal evidences, initial price decrease does not influence the performance of contractors.

Full textAbstract:
For most of projects, including major infrastructure enterprises a key success factor is an appropriately selected general contractor. In addition to technical and organizational criteria the assessment of its financial capacity is strongly important to provide liquidity to the cash flows of the project. Unfortunately, the practical experience of the construction market during the economic downturn shows that many projects have been delayed or suspended as a result of the bankruptcy of general contractors. The purpose of this paper is to present the results of studies on the use of Partial Least Square, Fisher Linear Discriminant, Support Vector Machine methods, and the authors' proprietary approach to the Extraction by Applying Weighted Criterion of Difference Scatter Matrices (EWCDSM) for the pre-qualification of potential contractors. The study included an ex post evaluation of selected large construction companies, operated in Poland by reference the fact of their bankruptcy or maintain the market to historical financial data for the prior year period. Then, for the same set of data the authors performed the identification of companies at risk of bankruptcy. The results obtained are confronted with the actual condition of the surveyed companies. Proposed operating models have been validated on publicly available financial data of construction companies listed on the Polish Stock Exchange.

The article investigates the problems in the legal regulation of relations in the field of contract work for state needs. Served as the basis for studies, the Federal Law № 44-FZ "On the contract system in the procurement of goods, works and services for state and municipal needs", which significantly changes the procedure for determining the contractors for the contract to perform works for the needs of the Russian Federation and its subjects . An exhaustive list of the types of trades that can be divided according to the following criteria: possible involvement in the definition of contractor: competition may be open, closed, competition with limited participation and closed tender with limited participation; as the form of the auction for the legislator directly calls only closed auction; in the form of placement: unlike the competition, the auction is possible in electronic form, depending on the number of stages of the competition can be carried out in two stages (two-stage competition) auction is always one step. Described in detail is the mechanism of bidding and auctions, and the author focuses attention on the selection of contractors performing work of good quality and others. Main factors that enable customers of construction works to ensure proper quality refer to the possibility of establishing additional requirements for the qualification of the contractor, the ability to perform work due to specification, material and technical base. Described are general requirements for all participants of the state order.

Full textAbstract:
In the public tender processes of large international contracts, the organizational legitimacy is considered a prerequisite to limit the risk of engagement with companies that do not have it. The instrument usually used by the contracting parties is the Pre-qualification Questionnaire, which acts as a real entry barrier for contractors to participate in subsequent tenders. In this research we analyze the legitimacy requirement in tender processes. We focus on large contracts, mainly for the public sector but not limited to, based on documents accessible through public digital media. The research defines and provides content to the variables that shape the different legitimacy sorts required to the organizations to participate in large construction and trade tenders. The results suggest that the legitimacy requirements to the bidders are multidimensional, which entails that to participate in public tenders several legitimacy dimensions are evaluated. The weight of the different kinds of legitimacy in relation to the legitimacy global requirements is also analyzed.

Purpose The selection of the contractor, as a main participant of a construction project, is the most important and challenging decision process for a client. The purpose of this paper is to propose a multi-agent systems (MAS)-based contractor pre-qualification (CP) model for the construction sector in the frame of the tender management system. Design/methodology/approach The meta-classification and analysis study of the existing literature on CP, contractor selection and criteria weighting issues, which examines the current and important CP criteria, other than price, is introduced structurally. A quantitative survey, which is carried out to estimate initial weightings of the identified criteria, is overviewed. MAS are used to model the pre-qualification process and workflows are shown in Petri nets formalism. A user-friendly prototype program is created in order to simulate the tendering process. In addition, a real case regarding the construction work in Turkey is analyzed. Findings There is a lack of non-human-driven solutions and automation in CP and in the selection problem. The proposed model simulates the pre-qualification process and provides consistent results. Research limitations/implications The meta-classification study consists of only peer-reviewed papers between 1992 and 2013 and the quantitative survey initiates the perspectives of the actors of Turkish construction sector. Only the traditional project delivery method is selected for the proposed model, that is other delivery methods such as design/build, project management, etc., are not considered. Open, selective limited and negotiated tendering processes are examined in the study and the direct supply is not considered in the scope. Practical implications The implications will help to provide an objective CP and selection process and to prevent the delays, costs and other troubles, which are caused by the false selection of a contractor. Originality/value Automation and simulation in the pre-qualification and the selection of the contractor with a non-human-driven intelligent solution ease the decision processes of clients in terms of cost, time and quality.

Full textAbstract:
The essential characteristics of a construction investment project include, but are not limited to: individual, comprehensive, specialized, complex and multi-step nature of activities, significant time constraints, demand for different qualifications and resources (material, financial). The above characteristics are a potential source of risk, which makes it necessary to accurately describe the mutual relations of entities involved in the project - primarily in the scope of the content of a construction work contract. Its task is to settle the commitments of the parties, their rights and obligations, and the responsibility for actions taken at the stage of preparation and implementation of the investment, in order to ensure its safe and non-conflicting realization. Signing a construction work contract results in the assumption of specific responsibilities by each party. In practice there are numerous examples of contractual clauses, which constitute a gross violation of the safety and balance of the parties in the area of fair and even distribution of potential risk. Most often two groups of contractual provisions are observed in the content of works contracts. The first one contains an unreasonable limitation of the contractor's entitlements, the other includes the irrational extension of the contractor's obligations and the transfer of numerous consequences of potential risks. The incorrect, i.e. unequal division of risk and its consequences is the most common cause of disputes between parties to a construction work contract. The paper presents the issue of asymmetry in the allocation of risks and limitations in shaping the contents of the public procurement contract, in terms of the safety of parties to construction work contracts

A central issue in designing incentive contracts is the decision to reward agents’ input use versus outputs. The trade-off between risk and return to innovation in production can also lead agents with varying skill levels to perform differentially under different contracts. We study this issue experimentally, observing and verifying inputs and outputs in Indian maternity care. We find that both contract types achieve comparable reductions in postpartum hemorrhage rates, but payments for outputs were four times that of inputs. Providers with varying qualifications performed equivalently under input incentives, while providers with advanced qualifications may have performed better under output contracts.

According to the Italian regulation firms must qualify to bid in auctions for public work contracts worth more than 150,000 euros. In this paper, we investigate the link between the efficiency of infrastructure provision, and the Italian regulation concerning the firm's entry and qualification system, employing a large dataset on Italian public works contracts for roads and highways. First, firm's efficiency in public contracts' execution is estimated using a smoothed data envelopment analysis (DEA) bootstrap procedure. Then, the effects of the qualification system on firm's efficiency is evaluated using a semi-parametric technique that produces a robust inference for an unknown serial correlation between efficiency scores. Our analysis shows that fully qualified firms perform better than partially qualified firms.

Full textAbstract:
Successful development of a construction company under the market economical conditions depends on the number of contracts for construction works awarded to the company, usually on the competitive basis. The winner of a tender is chosen from the participants that have previously proved their qualification at the prequalification stage, on the basis of two criteria: bid price and construction period. Bid price is the key factor which is of the most importance to the client. It is based on contractor’s estimation of construction cost. The most common construction cost assessment methods use the valid estimate norms calculated on the basis of the averaged work costs which do not consider fluctuation of actual market prices for different kinds of resources and the chosen methods and technologies of facility construction. This paper aims to provide the basis for the development of accurate cost assessment method which is based on the actual market prices for all kinds of resources and on the methods and technologies of facility construction chosen be the contractor, rather than on the valid estimate norms. The main task therefore is the development of the key principles and sequence of construction cost assessment during preparation for tender. The offered assessment method is based on construction schedule illustrating the time association of all construction processes and is the basis for determination of the actual volume of the required resources and funds at each time point of facility construction. Given the many-sidedness of the arising problems, construction cost assessment should be conducted based on the following principles: construction schedule optimization; accounting of market cost of resources; generating the best plan of construction resource provision; cost minimization and financial flow optimization; risk accounting; project approach. Using these principles during assessment of facility construction cost within the framework of bid preparation allows increasing its competitive ability according to the main winner choice criteria – construction cost and periods.

The EPC mode is one kind of total engineering management mode. In EPC engineering, the contractor commitments the project design, equipment procurement and construction, etc, which does not mean that general contractor must complete personally the entire construction project. The general contractor of EPC engineering can subcontract a part of the works to some subcontractors. So it is very important for the general contractor to tighten up the management of subcontractors through rules on contract. In the paper, some existing problems in signing stage and performance stage are analyzed. To address the problems, some solutions are put forward, including paying attention to the relevant qualification of the subcontractors audit, setting up warning systems of sub-contract, conducting risk assessment of sub-contract variations, etc.

Full textAbstract:
The Wisconsin Department of Transportation (DOT), Madison, uses a quality management program (QMP) specification for acceptance and payment of hot-mix asphalt (HMA) pavement. The QMP allows for product acceptance on the basis of contractor quality control (QC) testing when verified by the Wisconsin DOT quality verification (QV) tests. The contractor is required to do daily QC testing of mix properties in a department-certified, qualified laboratory located at the plant site. The Wisconsin DOT maintains a QV program (QVP) and conducts QV tests to determine the quality of the final product. QV and QC test results are compared, and a mix is considered acceptably verified if the two results are within specified limits. When test results do not meet these limits, the Wisconsin DOT performs referee tests to determine mixture conformance, acceptability, and payment. In 2011, the Wisconsin DOT began to see significant increases in the number of requests for referee testing as a result of wide disparities between QC and QV laboratory test results. To investigate this disparity, the department initiated a round robin laboratory test program. Results from the investigation proved to be insightful. The program was expanded and is now a key component of the Wisconsin DOT annual laboratory qualification certification program. This paper describes the program, how it is administered, how tests results are analyzed, and how nonconforming laboratories are identified. Test results obtained from the program are presented and recommendations developed for program improvements. The program details should be useful to other state highway agencies that use contractor QC tests for acceptance.

Full textAbstract:
Development of a country is measured by the number and quality of modern and contemporary projects that have been and are being established. As the construction industry is the nucleus for the development of any country, the stages of each project are tracked and monitored. It was found that the procurement stage has the biggest and most important influence in the successful completion of the project with the desired results. This research aims to eliminate corruption in the procurement process, identify the additional factors relating to a contractor’s qualification that contribute towards an increase in the quality of the project; designing a computer programme that conducts the tender process electronically to avoid any human contact. The researcher designed a questionnaire which contains a number of factors that would increase the efficiency and quality of the project. The researcher distributed 50 questionnaire forms and received back 46 completed forms. The questionnaire outputs were analyzed by using the SPSS software which can be defined as a software package used in statistical analysis for data. After analyzing the results a nominal group session was held. This consisted of eight employees with technical, financial, legal, and supervisory and IT expertise. The work was collective and many questions were asked. All relevant factors were discussed. It was agreed to cancel three factors only as being irrelevant to the contractor's qualification process. The most significant findings were that if the organizations adopt the E-T system in the tendering process, corruption cases will disappear, the tendering process will be achieved with high level of integrity and transparency, and in order to implement the E-T system, the organization must be ready to change, the employees should have enough courage to adopt the system, and there would be a need for at least one person to play the role of champion/leader.
