Abstract

Purpose

The use of partnering has grown within the public sector of the UK construction industry. Central to partnering is the use of the partnering charter. The charter establishes the mutual objectives of the project team. The purpose of this paper is to investigate the types of objectives that are identified and the potential reasons for them.

Design/methodology/approach

A number of partnering workshops have been undertaken through one of the University of Salford's Enterprise Units, the Centre for Construction Innovation. Each of these generated a workshop report, which captured the discussions during the day. These have been analysed in order to establish the different mutual objectives that have been identified for different projects.

Findings

The results show that while the key issues of time, cost, quality and safety are still central to what teams identify as successful project delivery, issues surrounding management of relationships including external stakeholders, such as the public, are also prevalent. In addition, there is an increase in identified objectives surrounding sustainable development issues, covering social and environmental goals.

Originality/value

The findings provide strong indications that construction is moving towards a more complex regime of objectives in the context of value procurement and partnering arrangements. The objectives identified by the different project teams show that construction projects are now considering both soft management issues and sustainable development as central to the successful delivery of projects.

Abstract

Purpose

This study aims to develop a framework for the optimal selection of construction project portfolios for a construction holding company. The objective is to minimize risks, align the portfolio with the organization’s strategic objectives and maximize portfolio returns and net present value (NPV).

Design/methodology/approach

The study develops a multi-objective genetic algorithm approach to optimize the portfolio selection process. The construction company’s portfolio is categorized into four main classes: water projects, building projects, road projects and healthcare projects. A mathematical model is developed, and a genetic algorithm is implemented using MATLAB software. Data from a construction holding company in Iraq, including budget and candidate projects, are used as a case study.

Findings

The case study results show that out of the 34 candidate projects, 13 have been recommended for execution. These selected projects span different portfolio classes, such as water, building, road and healthcare projects. The total budget required for executing the selected projects is $64.55m, within the organization’s budget limit. The convergence diagram of the genetic algorithm indicates that the best solutions were achieved around generation 20 and further improved from generation 60 onwards.

Practical implications

The study introduces a specialized framework for project portfolio management in the construction industry, focusing on risk management and strategic alignment. It uses a multi-objective genetic algorithm and risk analysis to minimize risks, increase returns and improve portfolio performance. The case study validates its practical applicability.

Originality/value

This study contributes to project portfolio management by developing a framework specifically tailored for construction holding companies. Integrating a multi-objective genetic algorithm allows for a comprehensive optimization process, taking into account various objectives, including portfolio returns, NPV, risk reduction and strategic alignment. The case study application provides practical insights and validates the effectiveness of the proposed framework in a real-world setting.

Abstract

Purpose

The purpose of this paper is to construct a two-stage risk management framework for international construction projects based on the meta-network analysis (MNA) approach. A plethora of international construction studies seems to assume risks as independent and therefore, risk intervention strategies are usually critiqued as ineffective.

Design/methodology/approach

In the risk assessment stage, a multi-tiered risk network structure was developed with the project objectives, risk events, risk factors and stakeholders, and critical risk factors were selected based on a series of calculations. In the risk intervention stage, targeted risk intervention strategies were proposed for stakeholders based on the results of the first stage. A highway construction project in Eastern Europe was selected as a case study.

Findings

The results showed that 17 risk factors in three categories – external, stakeholder-related and internal – are critical, and the project manager, construction management department, supplier and contract department are the most critical stakeholders that affect the entire project performance. Based on the critical risk factors and project stakeholders, targeted risk intervention strategies were proposed. The risk assessment results of MNA were found to be more reliable and consistent with the project conditions than the risk matrix method; the risk intervention strategies of MNA can effectively address project objectives.

Originality/value

This study modeled risk priorities based on risk associations and put forward a new method for risk management, supplementing the body of knowledge of international construction. The results of this study are of critical importance in management practices.

Abstract

Purpose

Project bundling is an innovative practice that groups or bundles several infrastructure projects into a single contract. While project bundling has various benefits, agencies are facing some challenges when bundling their projects, including properly assessing the feasibility (or infeasibility) of project delivery methods (PDMs) of interest. More specifically, project owners face the challenge of properly selecting between traditional and alternative PDMs for their bundled projects. Although some research efforts were devoted to providing guidelines in relation to different aspects related to project bundling, no previous study was conducted to help project owners performing PDMs-related feasibility analysis for bundled projects, which differ from normal, singly delivered projects. To fill this knowledge gap, this paper develops a decision-support tool that assists agencies in deciding whether they should select a traditional or alternative PDM (i.e. whether to go with the Design-Bid-Build (DBB) PDM or not) for their bundled projects.

Design/methodology/approach

An analytical methodology comprised of four main steps was followed in this paper. First, an expert survey was developed and distributed to industry experts to quantify the importance of 25 project bundling objectives. Second, principal component analysis was used to determine the weights for the different project bundling objectives. Third, a series of statistical tests was implemented to identify different feasibility tiers. Fourth, a user-friendly decision-support tool was developed, and its capabilities were demonstrated.

Findings

The results showed that six tiers exist to classify the feasibility (or infeasibility) of traditional PDMs (i.e. the DBB method) for bundled projects. The research outcomes have also reflected that the following five project bundling objectives contribute the most to making traditional PDMs (i.e. the DBB method) more feasible for bundled projects: (1) Having well-defined design features; (2) Requiring prior knowledge or experience with similar project size and scope; (3) Completing the overall project on schedule; (4) Keeping rate of expenditures within cash flow plan; and (5) Acquiring specific legislative, regulatory and jurisdictional requirements early on.

Originality/value

This research adds to the body of knowledge by equipping agencies and project owners with a decision-support system that helps them identify whether traditional or alternative PDMs are more appropriate for the specific objectives of their bundling program(s). By making the right PDM decision, project owners can enhance their bundling practices (especially in relation to the PDM proper selection) and ultimately the performance of their bundled projects.

Abstract

Purpose

Recently, there has been increasing focus on the development of multi-skilled workforce in project management. The purpose of this paper is to investigate a multi-skill project scheduling problem (MSPSP), which combines project scheduling and multi-skill personnel assignment. The distinct features of skill evolution and cooperation effectiveness are considered in the problem to maximize the total project effectiveness and skill development simultaneously.

Design/methodology/approach

The Bi-objective non-linear integer programming (LIP) models are formulated for the problem using three types of skill development objective function: number of experts, total skill increment and “bottleneck” skill increment. Non-linear models are then linearized through several linearization techniques, and the ε-constraint method is used to convert the bi-objective models into single-objective models.

Findings

A construction project case is used to validate the proposed models. In comparison with models that do not consider skill evolution and cooperation effectiveness, the models proposed in this paper offer more realistic solutions and show better performance with regard to both project effectiveness and skill development.

Originality/value

This research extends the current MSPSP by considering skill evolution based on the “learning effect” as well as the influence of cooperation in an activity-based team, which are common phenomena in practice but seldom studied. LIP models formulated in this paper can be solved by any off-the-shelf optimization solver, such as CPLEX. Besides, the proposed LIP models can offer better project scheduling and personnel assignment plan, which would be of immense practical value in project management applications.

Abstract

Purpose

The purpose of this paper is to define and analyze causal factors shaping the effectiveness of engineering, procurement and construction (EPC) major projects in meeting the product objectives, from the end-user’s perspective.

Design/methodology/approach

An online survey questionnaire was developed and administered to end-users working in major oil and gas projects. Data collection process was initiated on, around 275 end-users, and 213 responses were received, achieving a high response rate of 77 percent.

Findings

The results indicate that both alignment of objectives and end-user’s engagement factors exhibit a positive influence on effectiveness of EPC, with the former having higher contribution than the latter. In this context, the product success triangle reveals higher preference of the end-user’s team toward quality than schedule and cost objectives.

Research limitations/implications

Shifting the efforts of involving the end-user forward in time, starting from the planning stage, alleviates the adverse impacts of design changes as well as increases the ability to save cost, improve performance and increase end-user’s satisfaction.

Practical implications

The model raises the awareness of oil and gas industry practitioners toward the critical factors influencing the project effectiveness and proposes useful techniques for maintaining proper alignment between project and product objectives as well as facilitating end-user’s engagement at the site level. As such, it can serve as a motivation tool for aligning the objectives and acknowledging the engagement, with the aim of achieving the product success.

Originality/value

The effectiveness of EPC structural model was developed and tested using PLS–structural equation modeling statistical technique. The interpretation of the structural model demonstrated that both end-user’s engagement and alignment of objectives are essential to successfully achieve project effectiveness.
