Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality

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.

Abstract

Purpose

This paper aims to evaluate the existing and emerging Offsite Construction (OSC) skills. Construction industry is inherently labour oriented, fashioning poor labour productivity, low sustainability, slow and costly processes. These shortcomings promote OSC alongside driving forces such as industrialisation, automation and digitalisation. However, the traditional construction skills are not on par with the complexity, where robots, co-bots and digital-driven automated systems create the need for novel OSC skills.

Design/methodology/approach

Data collection is executed through a Roundtable activity hosting Construction Management academics form Australian universities specialising in construction technology. They engaged in ranking of skills along with creating a word cloud for the question, “what are the future construction skills that will be more beneficial in an OSC platform?” Word cloud is reviewed in a discussion approach while skills ranking data is analysed using descriptive statistics.

Findings

The most prominent OSC skills are logistics manager, project manager and digital producer. Attributes of skills that come under construction trades workers, design, engineering and specialist professionals will vary based on onsite-offsite percentage combination in a construction project. Study reviews the required construction skills at two ends of a continuum featuring the trade-based skills; bricklayer, concreter and carpenter at one end (traditional build) and the heavily digitalised and automated skills at the other end (OSC). The noticeable transition towards OSC urges industry practitioners, policy-makers and education providers to focus on understanding and cultivating key OSC skills.

Originality/value

This study describes the transition of skills from onsite to OSC. It is presented as one of the earliest attempts to evaluate OSC skill profiles.

Abstract

Purpose

Public–private partnerships (PPPs) are notoriously prone to disputes among stakeholders, some of which may unduly jeopardize contract performance. Contract disputes arising in Iran are often due to inefficiency of PPP concession agreements and practice. This study presents a causal-predictive model of the root causes and preventive measures for inter-organization disputes to enhance the likelihood of achieving desirable performance in PPP projects.

Design/methodology/approach

A theoretical “causal-predictive” model was developed with fourteen hypotheses based on extant literature and contractual agency theory, which resulted in the creation of a pool of 110 published items. Data were obtained from a questionnaire survey with 75 valid responses, completed by 4 stratified groups of Iranian PPP experts. Partial least square structural equation modeling (PLS-SEM) was used for validating the proposed model via a case study.

Findings

Results reveal that the main three factors of PPP desirable performance are as follows: on-time project completion, high quality of activities/products and services for public satisfaction. Further, the most influential factors of the lifecycle problems, construction stage, and preferred risk allocation included risk misallocation, improper payment mechanism and failure to facilitate a timely approval process.

Originality/value

For researchers, the findings contribute to the theory of contractual agency; specifically, how different influences among the model's elements lead to better PPP performance. In practical terms, proposed outcome-based strategies will inform PPP stakeholders to avoid dispute occurrence and thus improve the time, quality and services of projects.

Abstract

Purpose

Optimisation of daylight admission through window is crucial for alleviating glare while maintaining useful daylight levels in order to enhance occupants' health, visual comfort and moderating lighting energy consumption. Amongst various solutions, fixed external shade is an affordable solution for housing spaces that need to be sophisticatedly designed, especially during the period of increasing home spaces as working environments. In the humid subtropical region, daylight control plays an important role in indoor comfort, particularly with areas with a high window to wall ratio (WWR). Due to the insufficient amount of such study on non-office spaces in Australia, shading-related standards are not addressed in Australian building codes.

Design/methodology/approach

The chosen methodology for the research is a quantitative data collection and analysis through field measurement and simulation simultaneously. The first step is a multi-objective optimisation of shading elements through a non-dominated sorting genetic algorithm (NSGA-II) on parametric modelling via Rhino3D CAD and simulation engines (DIVA and ClimateStudio). In the second phase, the Pareto front solutions are validated by experimental measurements within a room with a single north-facing window (the most probable for the daytime glare in Sydney) for the seven most common local window configurations.

Findings

Through the simulation of ten genes, 1,560 values and 2.4 × 1,019 of search space, this study found an optimum shade for each local common window layout, resulted in +22% in (UDI) and −16% in views with discomfort glare on average. Moreover, an all-purpose polygonal shade showed an average of 4.6% increase in UDI and a 5.83% decrease in the percentage of views with discomfort glare.

Research limitations/implications

The findings are subject to the room dimensions, window dimensions and layouts, and orientation of windows for selected residential buildings in Sydney.

Originality/value

The study contributes to the development of highly accurate fixed external shading systems with rectangular and tapered-form external shapes. A real-time measurement by luminance-metre sensors and HQ cameras located at six eye levels is conducted to corroborate simulation results of the visual comfort.

Abstract

Purpose

Legal remedies are incorporated into international construction joint ventures (ICJVs) to mitigate contractual breaches. The effectiveness of remedies is predicated on two conditions; the comprehensiveness of the contract and its enforceability within the jurisdiction of interpretation. Relational-related weaknesses contribute to contracting parties placing a premium on the contract's capacity for mediating the relationship. However, contracts are not always enforceable. This study aims to examine means by which joint venture relational governance can be maintained under conditions of minimal legal recourse.

Design/methodology/approach

A relational contracting (RC) theory was used as the theoretical underpinning of the paper. Data were collected and analyzed following a multiple-case study approach from case projects in which ICJVs' was used.

Findings

The findings reveal (1) 17 relational and contractual governance problems; the main six being contractual flexibility, contractual joint venture system, contract reviewing, project conflict, national culture and leader–follower transgressions; (2) relational and contractual governance problems are managed differently, depending on financing sources and partners' national culture; and (3) that a developed RC-based framework comprising four stages is able to facilitate relational and contractual governance in ICJVs.

Originality/value

This study is novel in providing a guided approach to developing non-legal remedies for the mitigation of contractual breaches in ICJVs, grounded in theory and contextualized for the construction sector.

Abstract

Purpose

Industry 4.0 is exacerbating the need for offsite construction (OSC) adoption, and this rapid transformation is pushing the boundaries of construction skills towards extensive modernisation. The adoption of this modern production strategy by the construction industry would redefine the position of OSC. This study aims to examine whether the existing skills are capable of satisfying the needs of different OSC types.

Design/methodology/approach

A critical literature review evaluated the impact of transformative technology on OSC skills. An existing industry standard OSC skill classification was used as the basis to develop a master list that recognises emerging and diminishing OSC skills. The master list recognises 67 OSC skills under six skill categories: managers, professionals, technicians and trade workers, clerical and administrative workers, machinery operators and drivers and labourers. The skills data was extracted from a series of 13 case studies using document reviews and semi-structured interviews with project stakeholders.

Findings

The multiple case study evaluation recognised 13 redundant skills and 16 emerging OSC skills such as architects with building information modelling and design for manufacture and assembly knowledge, architects specialised in design and logistics integration, advanced OSC technical skills, factory operators, OSC estimators, technicians for three dimensional visualisation and computer numeric control operators. Interview findings assessed the current state and future directions for OSC skills development. Findings indicate that the prevailing skills are not adequate to readily relocate construction activities from onsite to offsite.

Originality/value

To the best of the authors’ knowledge, this research is one of the first studies that recognises the major differences in skill requirements for non-volumetric and volumetric OSC types.

Abstract

Purpose

The construction industry is currently responding to pressures of industrialisation happening across all sectors. Consequently, offsite construction (OSC) has become a vehicle to achieve industrialisation. This requires changes in traditional construction processes resulting in possible changes in construction skill requirements. Accordingly, the purpose of this study is to identify and review prevailing OSC practices and skills in the Australian construction industry. This study aims to critically analyse the existing skill profile classifications through a single case study and identify the need for an OSC specific skill classification.

Design/methodology/approach

This study follows a case study design, with an in-depth analysis of a single construction project. Only one case study was studied because scientifically, one example was enough to prove that the prevailing skill classifications do not represent OSC skills in a modern context. Data was retrospectively collected through semi-structured interviews of project stakeholders representing design, manufacture and assembly. Content analysis was conducted to analyse the collected data and produce findings.

Findings

This study identifies the inadequacy of the existing classification system, unavailability and the need of OSC specific skill categorisation. It highlights new skills that enter OSC; building information modelling engineer, three-dimensional draftsperson, OSC project manager and project coordinator, which are not identified in the available Australian skill classifications. These, together with existing skills need to be carved in to create a new skill classification.

Originality/value

This study is the first of its kind where a comprehensive OSC project is evaluated as a case study to determine OSC skill classification requirements in Australia.
