Uncertainty in best value decision making
Steve Phillips, Steve Phillips
• The sheer volume of decisions taken within the public sector procurement process prevents perfect and complete information being obtained and applied to every best value tender analysis that is carried out. As such, uncertainty must be accepted as a feature of the best value decision-making process. • This paper reports research which is developing a methodology for utilising the uncertainty component in best value tender analysis in order to create a more transparent decision making process. • The main output of the research is the production of a robust support tool which aids the multi objective decision making process within the public sector of the UK construction industry by provoking rational discussion with respect to; the industry's key performance indicators (KPIs), the client's attitude to risk and provides a transparent audit trail of the decisions taken. • The underlying rationale for the support tool is based on a combination of the Analytic Hierarchy Process (AHP), Multi-Attribute Utility Theory (MAUT) and Whole Life Costing (WLC). The paper demonstrates the practical utility of the methodology of the tool through a tender decision process.

The purpose of this paper is to assess the pattern of quantity surveying practice in the informal sector of the Nigerian economy. The specific objectives are to assess the awareness and utilisation of quantity surveying services, means of securing commission, type of services rendered and remuneration structure. Survey research method, using questionnaire, was adopted for the study. Primary data were elicited from the practicing quantity surveyors and the prospective clients utilising the services of quantity surveyors in the informal sector of Ogun State, Nigeria. Out of the 648 building owners in the study area, 50% (348) were systematically selected for sampling. In addition, a census of the total 27 quantity surveyors in Ogun State was surveyed. The data obtained were analysed using both descriptive and inferential statistics. While the patronage of quantity surveyors was revealed to be low, preparation of schedule of materials was the most utilised quantity surveying services and the most frequent means of securing commission was through friends. The payment structure was mostly by negotiation. It was concluded that awareness of quantity surveying services, means of securing commission and ability to pay for services rendered were significant in the pattern of quantity surveying practice in the sector.
GOVERNING CONSTRUCTION PROJECT PROCUREMENT to MITIGATE CONTRACTOR'S Opportunism: A CONCEPTUAL FRAMEWORK
Olusola Ogunsina
The opportunism construct has received limited attention in the construction procurement literature. Yet it has been shown that opportunism is inimical to value creation in interorganizational exchanges. This work focuses on contractor’s opportunism, synthesizing insights from the transaction cost economics literature, agency theoretic literature, relational exchange theory and the construction procurement literature into a testable conceptual framework that answers the questions: What causes construction contractors to behave opportunistically? What governance devices are in use for mitigating contractors’ opportunism? The work deploys a desk-top review and synthesis of relevant construction project management and business management literature. Since this work is conceptual, future researches will test the hypotheses embodied by the conceptual framework. Hypothetical propositions that specify the mitigating impact of governance structures on contractor’s opportunistic behaviours are developed. Sound procurement policies that improve project delivery in the public sector cannot be crafted without a deep understanding of the opportunism construct. This study illuminates our understanding of contractor’s opportunism, while providing a basis for assessing the efficacy of extant governance devices in a future empirical questionnaire survey.

Key attributes underpinning different markup decision between public and private projects: A China study
Dr Kunhui YE, Bo Xia
In the construction industry, contractors have to improve the efficiency of markup decision-making to survive from fierce business competition. The effect of client type on markup decision has been aware in previous studies and contractors are advocated to take account of decision factors properly when they are confronted with different types of projects. Nevertheless, the rationales behind the inclusion of different factors in markup decision-making for different projects are unknown. In this study, fifty-three factors were identified after extensive literature review and interviews with professionals. The identified factors were afterwards grouped under the headings of nine attributes and compiled in a questionnaire for survey in China. Using the Hotelling's T-square test, it is found that three attributes (i.e., project characteristic, client characteristic, and macro condition) can explain the effect of client type on contractors' markup decision. The research findings provide useful insights into the cognition of bid pricing as well as the improvement of bidding efficiency. While the research works were situated in China, contractors in other countries could benefit from the research findings in a similar vein.
Contractor selection using the multiattribute utility theory

zedan hatush
Literature and past research suggests that one of the reasons for the poor performance of the construction industry is due to the inappropriateness of the awarded contractor. In order to ensure a successful completion of a project, a comprehensive and careful assessment of contractors data in a prequalification stage is required. Appointing an appropriate contractor to carry out the construction work, therefore, becomes one of the most important tasks to ensure the success of a project. In this thesis the author has made a preliminary survey to investigate the bidding process currently used in the construction industry through literature survey, extensive interviews with the construction professionals and an industry wide questionnaire. The investigation has focused on the procedures of prequalification and bids evaluation, it also covers the list of criteria considered for selecting contractors in prequalification and bid evaluation stages. The thesis investigated the perceived rel...

Researching decision support: what do we need to know?
John Rooke
The EPSRC funded KIM Grand Challenge project to investigate the use of Knowledge and Information Management techniques in the context of the emerging product-service paradigm in engineering is introduced. The paper focuses on the topic addressed by Task 3.3 of this project, decision support. An outline is offered of an approach to decision support which combines the Unique Adequacy (UA) requirement of methods with Transformation-Flow-Value (TFV) theory. UA requires that reports are [1] grounded in a detailed inside knowledge of the topic and [2] are theory neutral. TFV theory emphasises the importance of flows in the analysis of production. It is suggested that these two approaches may be usefully combined to facilitate: [1] the design of through life decision support; and [2] the creation of the through-life community of practice which makes possible the sharing of information across the whole product-service life cycle.

Predicting Cost Performance of Construction Projects from Projects Procurement Procedure
2021 •
Awodele Abraham
The purpose of this paper is to show by multivariate regression model if a defective procurement procedure leading to a contract award affects the smooth execution of a project in terms of its cost performance on the strength of the significance of the model. This investigation was conducted with a quantitative method of research by administering questionnaires to key industry players (clients, consultants, and contractors) engaged in construction projects (both civil and building works) in assessing contract award procedures, conditions for contract award after tender evaluation and criteria for contractors’ prequalification. Data from their field survey was analysed with mean item score to show hierarchal importance of factors and critical evaluation using multivariate analysis of variance. Findings showed that a poor and inappropriate contract award procedure has divergence from efficient project cost management based on the corollary of mean score values of contract award proced...
