Reinvigorating the process of contractor selection in adaptive reuse projects: a novel decision-making and evaluation paradigm

Adaptive reuse projects reconfigure and revitalize existing buildings to enact an alternative purpose, diverging from the original design intent. The study introduces a novel decision-making framework that adopts the Ordinary Priority Approach (OPA) based on the integrated Relative Performance Index (RPI) for selecting and appraising contractors in adaptive reuse projects. Current methodologies lack criteria and assessment approaches tailored to the prototypical challenges of adaptive reuse projects, compelling special knowledge, skills, structural design considerations, sustainable methods, and prudent resource conservation. Accordingly, this research aims to 1) Identify and evaluate primary Contractor Selection Criteria (CSc) and their sub-criteria influencing contractor choice for adaptive reuse; 2) Rank sub-CSc using the Relative Importance Index (RII); 3) Assign weights to sub-CSc via the OPA, and 4) Examine the contractors’ performance using the RPI method. By offering this framework, this paper enhances and empowers decision-making processes to opt for contractors with the requisite expertise and competencies for successful adaptive reuse projects, filling a crucial knowledge gap. Six contractors were selected to assess the feasibility and validate the proposed framework. Among the chosen contractors, numbers 2, 4, and 5 exhibited significant performance concerning the top-ranked sub-CSc, registering RPI values of 1, 0.88, and 0.86, respectively.

Proposed Improvement of Contractor Selection for Maintenance of Reactor Effluent Air Cooler Using Value-Focused Thinking and Analytic Hierarchy Process at PT KPI RU V Balikpapan

PT KPI RU V Balikpapan performs turnaround to ensure equipment reliability for domestic oil and natural gas production. The Reactor Effluent Air Cooler (REAC) is an important refinery secondary process equipment. Experience in earlier maintenance showed that repeated work on the equipment’s welding tube required further repair processes until it met welding compliance criteria. REAC repair rejections exceeded the 2% target at 43%. Welding on furnaces and tubes was repeated, consequently resulting in delays of work completion that may cost money. The study identified contractor selection criteria using Value-Focused Thinking (VFT). After consulting Subject Matter Experts and Management, five contractor selection criteria were identified: Safety and Health, Technical Ability, Management Capability, Reputation, and Financial. The contractor selection consider uses the Analytic Hierarchy Process (AHP) based on selection criteria. Contractor APL is the best alternative with a 57% score. AHP methods on goods and services procurement can improve contractor selection at the pre-qualification or tender evaluation phase.

Assessing Contractors’ Selection Criteria for Improved Project Delivery


 This research assesses the project delivery criteria for evaluating construction contractor, with specific application to construction projects in Jos. The paper adopted questionnaire survey conducted on construction professionals. Structured questionnaire was administered to 170 professionals to elicits information’s on criteria used for assessing contractors, out of which 148 representing 87.06% properly filled questionnaires were analyzed. The respondents were asked to rank 10 major criteria for selecting a contractor, 6 reason for selecting contractor base on bid, 5 factors on the need for selecting a contractor as conceptualized and identified from the literature. The study deployed descriptive statistics such as relative importance index, mean rating and mean ranking for data analysis. The project delivery criteria were analyzed and the results indicated that base on bid with RII of 0.89, low price with RII of 0.88 and financial stability with RII of 0.86 were ranked as major criteria for selecting capable contractors. It was reasonably competitive, and the offer was close to our estimate, were rated high as factors for evaluating contractors base on bid. For selection of the most appropriate contractor and to fulfil the sponsor or other stakeholder’s requirement were rated high on the need for selecting a contractor. The identified factors were therefore recommended as criteria’s to be considered for assessing contractor for improved project delivery. Furthermore, this research will help decision makers, clients and others involved in construction project delivery to be well informed on contractor selection criteria that influences construction project delivery

Influence of Contractor Selection Criteria on Critical Success Factors of Public Project Delivery in Abuja

There are so many contractors that are not technically and managerially competent. This makes contractor selection processes an onerous task to be performed by the client. Yet, without a proper and accurate method for selecting the most appropriate contractor, the performance of the project will be affected denying clients value for money. Therefore, the study assessed the Influence of contractor selection criteria on critical success factor of public project delivery in Abuja, Nigeria using self-administered structured questionnaires to construction professionals. It was discovered that experience, financial capability, and technical capability are widely considered criteria in the selection process while all the critical success factors for project delivery are very much crucial and that procurement related factors, project stakeholders’ related factors, and daily site factors are essential factors to effective project delivery. The study concluded that there exists a significant relationship between the factors considered in selection of contractors and the criteria success factors. Based on the relati0nship between selection criteria and success factors, there is the need to adopt the selection criteria for each individual project based on project characteristics, client characteristics and external environment for effective project delivery. It is necessary to make good assessment of the technical capacity and experience of the contractors when considering the costfactor for project delivery.

Ranked generic criteria for EPC contractor selection

PurposeThe purpose of this study was to prioritize the appropriate generic contractor selection criteria for Engineering–Procurement–Construction (EPC) projects in the construction industry.Design/methodology/approachProceeding from a review of previous studies and validation by a small group of experts, a preliminary set of 16 criteria was first identified. This was followed by three rounds of Delphi surveys: firstly, with 64 experienced participants confirming the relevance of the 16 criteria; secondly, with a reduced subgroup of 47 more experienced participants scoring the importance of each; and finally, providing the opportunity for these 47 to revise their scores in the light of knowing the aggregated results of the previous round.FindingsThe results show the consensus view, of which the most important criteria are ranked as past performance, project understanding, technical attributes, key personnel, health and safety, past experience, time, management, financial, contractual and legal, quality, cost, relationships, environmental and sustainability, organizational and industrial relations, and geographic location.Originality/valueThe findings are useful for both practitioners and academics in making a significant contribution to the body of knowledge of the EPC process. This will assist in providing a better understanding of criteria importance and pave the way to developing an EPC contractor selection model involving the criteria most needed to objectively identify potential contractors and evaluate tenders.

Building Construction Clients’ Design Consultant and Contractor Selection Criteria Versus Post-Occupancy Satisfaction Levels

In today’s competitive building construction markets, achieving clients’ satisfaction is of utmost importance. The choice of a design consultant and a contractor for a building project has a crucial influence on the post-occupancy satisfaction of the client. Hence, this study provides insights into private building construction clients’ perceptions of a set of criteria contributing to their selections of design consultant and contractor together with the resulting post-occupancy overall client satisfaction levels eventually reached, by presenting survey findings of 330 clients in North Cyprus construction market. Unlike previous studies, the current study combined all the interrelated and vital stages of design consultant and contractor selection with post-occupancy client satisfaction levels. A further contribution is differentiating among various types of client groups’ behaviors in each of the three specified stages. Clients in different categories had distinct approach differences in selection stages, and different post-occupancy satisfaction values indicating that firms may benefit from market segmentation. “Residential” and “<120,000£” type building clients were the least satisfied groups, while “project execution stage” and “functionality” emerged as major features creating dissatisfaction. The findings revealed the importance attached by the clients to “references about the firm” in the selection stages and low client satisfaction with the completed projects. Regression analysis findings revealed different design consultant and contractor selection factors predicting overall clients’ satisfaction while assigning high importance to the “cost-effectiveness approach of the firm” emerged as the only strong predictor of dissatisfaction. This study provides a guide for building construction clients to attain higher post-occupancy satisfaction and assists design consultants and contractors in adopting specific customer-focused strategies.

Identification of Health and Safety Prequalification Criteria for Contractor Selection in Construction Projects: A Systematic Review

Selecting an appropriate contractor is a crucial phase that clients normally conduct to execute projects. Extensive research has been conducted on the main contractor selection criteria such as financial stability and technical and management capability. However, few studies focusing on health and safety criteria are being used to assess contractors’ safety performance in the existing selection process. Hence, this paper aims to analyse the existing literature on health and safety criteria for contractor selection in construction. The articles were retrieved using developed search string from renowned databases such as Scopus, Ebscohost, Web of Science, Science Direct and Dimensions. This search resulted in a total of 38 papers which can be systematically reviewed. Six main themes were discovered to represent safety prequalification criteria for construction projects, namely, experience and work history, safety control system, safety policy and management, accident rates and records, safety promotion and environmental concerns. Under these six main themes, there are 25 safety prequalification criteria that have been substantially published in previous literature, and the most-cited criteria are examined. This study brings a significant contribution to construction industry professionals, especially clients, when selecting a capable contractor in construction projects. By identifying the safety prequalification criteria, clients can assess a contractor’s efforts in ensuring safe execution of a project before awarding the contract to them. Additionally, the findings of the present study could contribute towards developing a comprehensive framework on contractor selection criteria that incorporates safety leading and lagging indicators.

Contractor selection: a review of qualification and pre-qualification systems

The impact of contractor selection on construction project success has led to numerous studies on contractor selection. However, an up-to-date systematic review of contractor selection trend is still lacking. This study aims to fill the gap by reviewing published literature from 1990 to 2019. A desktop search was conducted under the ‘T/A/K (title/abstract/keyword)’ in Scopus search engine where 252 papers were identified. Based on a two-phase filtering approach, which included journal relevance assessment and article relevance assessment, 137 published papers within 22 journals were used for the study. The major finding was that the questions were raised on the suitability of selection criteria for appraising contractors and it was acknowledged that, choosing appropriate contractor selection criteria are affected by other factors hence can be regarded as a Multiple Criteria Decision Making problem suitable for machine learning tools. A major limitation of was that, even with the 137 reviewed papers, not all contractor selection-related papers were reviewed. The outcome of the study suggests a greater involvement of practitioners in model development and stimulates future studies that delve into the development of models to aid in selecting optimal contractor selection criteria for a particular project.

Key contractor selection criteria for green construction projects in the UAE

Selecting the appropriate contractor is of paramount importance to the success of any construction project. This is even more important to green construction projects. There is a noticeable surge in the number of green construction projects. Green construction projects require contractors that have certain capabilities in addition to the traditional capabilities. This article highlights the key criteria for selecting contractors for green construction projects. Twenty criteria were identified based on literature review. These criteria were categorized into five groups: firm characteristics, firm record, commercial and technical bid, environmental and socio-economic. A survey was then developed and sent to professionals from the United Arab Emirates (UAE). The respondents evaluated the selection criteria using pair-wise comparison using the Analytic Hierarchy Process. Forty-eight responses were collected. The results show that the top five criteria are the bid price, energy management, technical bid, proposed time and water management. The results show that sustainability-related criteria (environmental and socio-economic groups) are important with a combined weight of 0.386.

Competitive Environment Assessment and the Contractor Selection Criteria for the State and Municipal Contracts Execution

The article deals with the competitive environment assessment in the investment and construction complex and specifics of the contract system implementation in the procurement of goods, works and services provided for state and municipal institutions. Being a key element in the state construction order implementation and assessing the level of competitiveness of the investment and construction complex enterprises, the contractual bidding mechanism acts as the basis for competitive relations, simultaneously legislating the main price criteria for the selection of contractors, which do not allow to objectively evaluate the applicants' ability to fulfill the conditions of the concluded contract in full.

Contractor Selection Criteria: a Study on Malaysian Public Construction Projects

The complexity of a construction project renders the implementation of a systematic approach in selecting contractors to be of vital importance, especially for the public construction projects. Nevertheless, public construction projects in Malaysia often suffer from delay, over budget and low-quality issues. These are very much affected by the contractors who tend to manipulate the tender price with the sole intention of getting the contract, thus led to many issues throughout the projects delivery. Hence, this paper is aimed to investigate a list of contractor selection criteria for public construction projects in Malaysia. A total of 43 selection criteria have been identified and categorised into seven categories from an initial review via content analysis. These findings were then verified via a questionnaire survey, which was responded by 276 local Malaysian construction industry practitioners. Data collected were analysed using the IBM Statistical Package of Social Sciences (SPSS). The analysis showed that all 43 selection criteria were significant in selecting contractors. It is hoped that the findings of this paper would encourage the governing bodies and authorities to consider the use of multi criteria assessment in selecting contractors for public construction projects, rather than being solely reliant on the tendered price.

Contractor Selection Criteria in Ghanaian Construction Industry: Benefits and Challenges

Selecting a contractor for construction project is a difficult decision to be taken by a client because it may lead to construction delivery problems or successful delivery of the project. This study, therefore, investigated the contractor selection criteria in the Ghanaian construction industry, considering the benefits and challenges. A quantitative research method was adopted in this study through the use of a questionnaire. The target population for the study consisted of registered contractors and consultants in the Ashanti and Brong-Ahafo regions of Ghana. It was found that though the construction professionals are well vested with the prequalification selection criteria that are being used within the Ghanaian construction industry, they were not familiar with multi-criterial section methods. It was also found that the benefits of the contractor selection criteria include: enabling the client to select contractors who are performers for the project, saving the project owner a lot of time, minimizing the possibility of contractor default, and facilitating the achievement of project success and the objectives within the scheduled time. Furthermore, excessive cost and time overrun, poor quality standard, imprecise assessments due to lack of information, criteria being very complex and difficult to apply in practice, among others were identified as the challenges to the contractor selection criteria in Ghanaian construction industry. The study recommends for further studies to determine the impact of the identified challenges on construction projects, and ways to minimize the challenges.

Factors Influencing Implementation of Commercial Housing Projects in Kisumu County, Kenya

The major factors contributing to this trend require more examination. This study sought to identify factors influencing implementation of commercial Housing projects in Kisumu County, Kenya. The research objectives were to: assess how contractor selection criteria, investigate how cost of materials and determine how project activity scheduling influenced implementation of commercial Housing projects in Kisumu county. The study was informed by agency and project implementation theories. The research design was descriptive survey. A survey questionnaire was applied in the study. The target population included contractors (215), National Construction Authority (NCA) officers (7) and county government building inspectors (7), from which a sample of 193 contractors and 14 NCA and county government officials was developed. Simple random and purposive sampling techniques were used in this study. Questionnaire (for contractors) and interview schedule (for NCA and county government officers) were the instruments of data collection for this research. The study adopted both qualitative and quantitative data analysis approaches. Qualitative data was analysed by content analysis while Quantitative Data for this study was analyzed descriptively (frequencies, percentages, means and standard deviation) and inferentially (Multiple Linear Regression). The findings are presented in the form of tables, charts and frequencies. Results showed that contractor selection criteria, budgeting and project scheduling significantly (p<0.05) affected the implementation of commercial housing projects in Kisumu County. The Multiple Linear Regression statistics showed that about 40.0% of change in implementation of commercial housing projects was explained by the factors studied. The beta coefficients for the equation was; cost of materials β=0.442, project activity scheduling (β=0.390) and lastly contractor selection criteria β=0.298. The study recommends that there is need for build-up of effective coordination and communication during project implementation. There is also need for consideration of previous contracts undertaken by a particular contractor before engaging them to implement a new project. The findings of the study are important to NCA, county governments, contractors, developers and other stakeholders in the construction industry.

The Contractor Selection Criteria in Open and Restricted Procedures in Public Sector in Selected EU Countries

This article presents a comparative analysis of the criteria used in the awarding of the contracts and appointing a contractor in the public sector in selected EU countries. For the purpose of conducting the analysis thirteen EU countries were chosen, e.g. Poland, Germany, United Kingdom, France, Italy etc.The regulations in all analysed countries are based on and comply with the EU Directive 2004/18/EC which states that the Public Procurement process can be carried out by using two basic procedures: standard and special. In this paper two criteria used in standard procedures have been compared. The results of the comparison showed that the choice of procedures vary remarkably between the countries, and similarly the proportion of criteria used in the award process, where price and price with other non-price criteria are used. The results are illustrated on the diagrammatic maps.

Ranking of the Main Criteria for Contractor Selection Procedures on Major Construction Projects in Libya Using the Delphi Method

The construction sector constitutes one of the most important sectors in the economy of any country. Contractor selection is a critical decision that is undertaken by client organizations and is central to the success of any construction project. Contractor selection (CS) is a process which involves investigating, screening and determining whether candidate contractors have the technical and financial capability to be accepted to formally tender for construction work. The process should be conducted prior to the award of contract, characterized by many factors such as: contactor’s skills, experience on similar projects, track- record in the industry, and financial stability. However, this paper evaluates the current state of knowledge in relation to contractor selection process and demonstrates the findings from the analysis of the data collected from the Delphi questionnaire survey. The survey was conducted with a group of 12 experts working in the Libyan construction industry (LCI). The paper starts by briefly explaining the general outline of the questionnaire including the survey participation rate, the different fields the experts came from, and the business titles of the participants. Then the paper describes the tests used to determine when the experts had reached consensus. The paper is based on research which aims to develop rank contractor selection criteria with specific application to make construction projects in the Libyan context. The findings of this study will be utilized to establish the scope of work that will be used as part of a PhD research.

Examining the influence of participant performance factors on contractor satisfaction: A structural equation model

Participant performance is critical to the success of projects. At the same time, enhancing the satisfaction of participants not only helps in problem solving but also improves their motivation and cooperation. However, previous research related to participant satisfaction is primarily concerned with clients and customers and relatively little attention has been paid to contractors.This paper investigates how the performance of project participants affects contractor project satisfaction in terms of the client's clarity of objectives (OC) and promptness of payments (PP), designer carefulness (DC), construction risk management (RM), the effectiveness of their contribution (EW) and mutual respect and trust (RT). With 125 valid responses from contractors in Malaysia, a contractor satisfaction model is developed based on structural equation modelling.The results demonstrate the necessity for dividing abstract satisfaction into two dimensions, comprising economic-related satisfaction (ES) and production-related satisfaction (PS), with DC, OC, PP and RM having significant effects on ES, while DC, OC, EW and RM influence PS. In addition, the model tests the indirect effects of these performance variables on ES and PS. In particular, OC indirectly affects ES and PS through mediation of RM and DC respectively. The results also provide opportunities for improving contractor satisfaction and supplementing the contractor selection criteria for clients.
