This paper covers the development of a multidimensional contract administration performance model (CAPM) for construction projects. The proposed CAPM is intended to be used by the industry stakeholders to measure the construction contract administration (CCA) performance and identify the strengths and weaknesses of the CCA system for running or completed projects.

The research design follows a sequential mixed methodology of qualitative and quantitative data collection and analysis. In the first phase, contract administration indicators were collected from relevant literature. In the second phase, an online questionnaire was prepared, and data were collected and analyzed using the crisp value of fuzzy membership function, and structural equation modeling (SEM). The fuzzy set was chosen for this study due to the presence of uncertainty and fuzziness associated with the importance of several key indicators affecting the CCA performance. Finally, SEM was used to test and analyze interrelationships among constructs of CCA performance.

The data collected from 336 construction professionals worldwide through an online survey was utilized to develop the fuzzy structural equation model. The goodness-of-fit and reliability tests validated the model. The study concluded a significant correlation between CCA performance, CCA operational indicators, and the process groups.

The contribution of this paper to the existing knowledge is the development of a fuzzy structural equation model that serves as a measurement tool for the contract administration performance. This is the first quantitative structural equation model to capture contract administration performance. The model consists of 93 Construction Contract Administration(CCA) performance indicators categorized into 11 project management process groups namely: project governance and start-up; team management; communication and relationship management; quality and acceptance management; performance monitoring and reporting management; document and record management; financial management; changes and control management; claims and dispute resolution management; contract risk management and contract closeout management.

The purpose of this paper is to examine the decision to contract school meal services and the associated nutritional and financial impacts on school districts. Given the increase in the use of competitive contracting of public school meal services and the critical role that school meal services play in public health, this is an important subject to investigate.

A case study was performed using one US school district with privatized food service. Face-to-face interviews were conducted with school food service decision makers. Other data collection included the analysis of public documents such as the school district’s budgets and financial statement reports (the cost per lunch and breakfast meals, the cost for labor, contract, transport, supplies and food expenses) and school food service policies (contract policies). Supplementary data pertaining to district social-demographic profiles and full-time equivalent enrollment figures were also collected from state departments.

Analysis of interviews revealed that positive financial motivations and impacts were dominant factors related to contracting food services in the district. A significant finding was the relatively short turnaround in the district’s negative financial situation as a result of contracting out the food services. These findings provide valuable insight and support for rural school districts in similar negative financial situations seeking to contract out food services.

Many studies have examined contracting out of technical services, such as transport and waste management, and social services, such as correctional services and health; however, there is a lack of studies documenting the effects of contracting out of school meal services.

In the construction industry, various parties are involved in a project. Consequently, claims and disputes are inevitable in this industry. This paper aims to develop Integrated project delivery (IPD) practices including early involvement of stakeholders and multiparty contracts which its combination with advanced technologies such as blockchain can lead to better dispute management and improve the whole construction process.

Based on literature review, the alternative dispute resolution (ADR) for IPD contacts were identified, and three formats of IPD contracts were selected, and the dispute resolution process of them has been analyzed. Then, based on blockchain review, a conceptual blockchain-based dispute management (BDM) model was generated for ADR in IPD. Model validation was done by an interview. Experts were asked to compare the BDM model with the traditional system regarding the ADR duration.

Analyses of the collected data from the experts demonstrated that the BDM model has better function in terms of time and cost for ADR process when the project is facing serious and considerable number of disputes. The relation between blockchain technology (BCT) and building information modeling (BIM) has been examined through a framework, and the ability of the proposed model for administrating dispute resolution process has been verified using four different scenarios of construction claims that show the system can run successfully.

The current study proposes a truthful model, reliable framework to address the problem of project dispute management in IPD contracts. The system combines the ability to being unchangeable and the reliability characteristics of BCT with informative and automation aspects of BIM together to improve dispute resolution issue in the IPD system.

The variance between the winning bid and the owner's estimated cost (OEC) is one of the construction management risks in the pre-tendering phase. The study aims to enhance the quality of the owner's estimation for predicting precisely the contract cost at the pre-tendering phase and avoiding future issues that arise through the construction phase.

This paper integrated artificial neural networks (ANN), deep neural networks (DNN) and time series (TS) techniques to estimate the ratio of a low bid to the OEC (R) for different size contracts and three types of contracts (building, electric and mechanic) accurately based on 94 contracts from King Saud University. The ANN and DNN models were evaluated using mean absolute percentage error (MAPE), mean sum square error (MSSE) and root mean sums square error (RMSSE).

The main finding is that the ANN provides high accuracy with MAPE, MSSE and RMSSE a 2.94%, 0.0015 and 0.039, respectively. The DNN's precision was high, with an RMSSE of 0.15 on average.

The owner and consultant are expected to use the study's findings to create more accuracy of the owner's estimate and decrease the difference between the owner's estimate and the lowest submitted offer for better decision-making.

This study fills the knowledge gap by developing an ANN model to handle missing TS data and forecasting the difference between a low bid and an OEC at the pre-tendering phase.

This paper examines the role of government procurement as a social policy mechanism within a multilateral open trading system. Government regulations globally are being transformed to foster more responsible business conduct in multinational enterprises (MNEs). Yet, concern that sustainability may present a discriminatory barrier to trade has stalled the progress of sustainable public procurement (SPP) at the international level, raising questions regarding the role and scope of the World Trade Organisation’s (WTO) Government Procurement Agreement (GPA) to align taxpayer-funded contracts with the United Nations (UN) Sustainable Development Goals.

With a focus on social sustainability, this paper reviews the grey and academic literature to assess the changing landscape of public procurement policy and supply chain legislation in high-income countries.

Frontrunner nations are adopting a mandatory approach to sustainable public procurement and due diligence legislation is elevating supply chain risk from reputational damage to legal liability. While technological innovation and the clean, green production of manufactured goods dominates the sustainable public procurement literature, the social aspects of sustainability poverty, inequality and human rights remain underrepresented.

The scope of this paper is limited to the examination of government procurement covered by the WTO-GPA (2012). Smaller value contracts, under the WTO-GPA thresholds and the category of defence are beyond the scope of the paper.

The paper focusses on the underserved topic of social sustainability in business-to-government (B2G) – business to government – supply chains arguing that for responsible business conduct to become a competitive advantage, it must be more meaningfully rewarded on the demand-side of all taxpayer-funded contracts in organisation for economic co-operation and development countries. The paper introduces the idea of priceless procurement as a mechanism to build system capacity in the evaluation of non-financial sustainability objectives.

To build the capacity to stimulate competition based on social and environmental policy objectives, the paper introduces the concept of priceless procurement in B2G contracts.

Competency frameworks can support public procurement capacity development and performance. However, literature on connecting professionalisation with national procurement contexts is limited. This paper aims to explain and conceptualise recent Romanian experience with developing bespoke competency frameworks at national level for public procurement that reflect the features of the Romanian public procurement system. The approach used could guide in broad-brush, mutatis mutandis, other (national) public procurement systems with comparable features, mainly those seeking a shift from a rather administrative function of public procurement towards a strategic function.

This case study reflects on the methodology used for analysing the Romanian public procurement environment in EU context to develop bespoke professionalisation instruments, and on ways to integrate competency management approaches in Romanian public procurement culture. That methodological mix has been mainly qualitative and constructionist, within an applied research approach. It combined desk research with empirical research and included legal research in this context.

A principled, methodological and pragmatic approach tailored to the procurement environment in question is essential for developing competency frameworks capable to resonate to and address the specific practical needs of that procurement system.

Competency frameworks can uphold societal objectives through public procurement.

Using valuable insights into the development of the Romanian public procurement competency frameworks, the paper provides a conceptual framework for instilling competency management approaches to public procurement professional development where the latter is governed by a rather distinct, public administration, paradigm. This conceptual framework can guide other public procurement systems and stimulate further research.

This article critically analyses the extent to which selected Public-Private Partnerships (PPPs) transportation projects in the Caribbean subregion embrace good practices and how they benefit the public sector.

The article begins with the general rationale of PPPs, leading to a discussion on the specific challenges of the Caribbean subregion and an assessment of certain critical projects. The sample cases include the L F Wade International Airport in Bermuda, the cruise berthing and cargo port redevelopment project in the Cayman Islands, and the Sanger International Airport in Jamaica. There are five aspects to the critical assessment: (a) an evaluation of the type of PPP arrangement used; (b) the legal/policy framework; (c) financial implications; (d) accountability; and (e) miscellaneous data. Desk-based research is conducted as supported by both international and local sources to convey a uniquely local perspective in this under-researched area of scholarship.

PPP frameworks in the Caribbean are improving quickly but remain a work in progress. Jamaica leads the region. Bermuda trails behind. Problems of legal compliance with frameworks and limited market engagement persist, leading to risk management problems.

This article fills a literature gap on critical analysis of individual Caribbean PPP transportation projects. Previous reports, mostly by international organisations, cover regional or sectorial trends. Other sources take a descriptive but not critical approach.
