Integrated digital delivery (IDD) is the use of digital technologies, data, and platforms to integrate work processes and connect all stakeholders working on the same project throughout the construction and building lifecycle. The benefits of digital technologies are often cited to justify the adoption of IDD in construction projects, but such benefits remain under-researched and unverified. The purpose of the paper is to investigate the performance improvements attributable to the IDD approach in construction projects.

This study combined questionnaire surveys, statistical analysis, social network analysis, and fuzzy synthetic evaluation to investigate the benefits of IDD in Hong Kong construction projects. The methodology was applied to rank the benefits of IDD, assess the benefit categories of the IDD, and model the relationships between the benefits.

The results showed twenty-two (22) significant benefits of the IDD approach, grouped into design, cost, collaboration, sustainability, procurement, and productivity benefits. Design and collaboration benefits were ranked at the top and “high quality and faster preparation of designs” and “improved information exchange and management” were the most important benefits in these clusters, respectively. The weighted network model showed that the benefits of IDD are significantly correlated, and “cost savings associated with digital project delivery”, “improved work and project quality”, and “high quality and faster preparation of designs and calculation” were identified as the most influential benefits.

The study outcomes offer the first empirical insights into performance gains achievable with the IDD approach in construction projects. Hence, this study, for the first time, identified and assessed the benefits and benefit categories as well as formulating the relationships between the benefits to suggest the most effective benefit pipeline.

This study examined the influence of information and communication technology (ICT) on Nigeria's trade in sectors. Specifically, the research evaluated the effects of internet penetration, mobile phone subscriptions and fixed telephone subscriptions on exports and imports.

The study considered data from 1995 to 2022, highlighting ten trade sectors per standard international trade classification (SITC) single digit. It utilised the panel auto-regressive distributed lag (ARDL) with a preference for a pooled mean group (PMG) estimator.

The study finds that, in the short run, increases in internet penetration, mobile phone subscriptions and fixed telephone subscriptions significantly decrease export levels in Nigeria. Nonetheless, ICT advancements, particularly in mobile and fixed telephone subscriptions, significantly boost import activities by 17.9 and 41.5% in the long run, highlighting their positive impact on trade dynamics. In the long run, mobile telephone subscriptions substantially negatively affect exports. In contrast, internet penetration and fixed telephone subscriptions show no significant impact, indicating differing influences of ICT components on trade over time.

The study underscored the need to prioritise enhancing ICT infrastructure to boost export growth, especially in sectors identified under the SITC framework. Strategies should be developed to mitigate the negative impacts associated with ICT advancements.

The study used the SITC framework, which presents different export and import sectors. It offers a distinctive examination of the short- and long-term effects of ICT on Nigeria's trade sectors. It also provided valuable insights into the impact of mobile and internet technologies on exports and imports, highlighting sector-specific effects and the need for strategic resource allocation.

Prefabricated construction has been rapidly developing and intensifying the reliance on the supply chain. The pandemic of COVID-19 induced severe disruptions to the supply chain operation and thus attracted the research attention on the supply chain resilience (SCR) under various events. Assessing the resilience of the prefabricated construction supply chain (PCSC) is essential for surviving the shifting disruptive attacks and ensuring consistent, reliable operation. Based on the ripple effect and supply chain performance (SCP), this study aims to develop an assessment model for SCR of PCSC.

Having identified the roles and material flows among stakeholders, a PCSC network is established. Utilizing the ripple effect model, it develops an assessment framework tailored for PCSCs, which then evolves into a comprehensive assessment model for evaluating the SCR by integrating the disruptive influence and the pre-and post-disruption SCP. Case study is then applied to validate the model.

Using SCP metrics and disruptive influence assessment as basic dimensions, the SCR can be assessed and expressed through a vector formula. Operating costs and asset utilization can effectively reflect changes in resilience, paying attention to their real-time changes can provide a better judgment of the current stage of disruptions.

The assessment model of SCR accounts for the ripple effect within prefabricated construction, offering a thorough understanding of how disruptions impact the entire supply chain network. Additionally, this model introduces a novel approach to evaluating SCR in reverse by leveraging SCP metrics instead of direct measurement, thereby minimizing potential biases.

Studies show that building information modelling (BIM) technology can improve construction productivity regarding the design, construction and maintenance of a project life cycle in the 21st century. Revit has been identified as a frequently used tool for delivering BIM in the built environment. Studies about BIM technology via Revit are scarce in training middle-level workforce higher education institutions. Thus, this study aims to investigate the relevance of BIM technology and offer measures to promote digitalisation in Nigeria’s built environment polytechnic undergraduates via Revit.

Given the unexplored nature of training the middle-level workforce in Nigeria, 37 semi-structured virtual interviews were conducted across Nigeria, and saturation was achieved. The participants were knowledgeable about construction-related BIM. The researchers used a thematic analysis for the collected data and honed them with secondary sources.

Improved visualisation of design, effective and efficient work productivity, automatic design and quantification, improved database management and collaboration and data storage in the centrally coordinated model, among others, emerged as BIM’s benefits. BIM technology via Revit is challenging, especially in Nigeria’s polytechnic education curriculum. The 24 perceived issues were grouped into government/regulatory agencies-related, polytechnic management-related and polytechnic undergraduate students-related hindrances in Nigeria’s built environment.

This study is limited to BIM implications for Nigeria’s built environment polytechnic undergraduates.

This study contributes to the literature paucity in attempting to uncover perceived issues hindering the implementation of BIM technology via Revit in training Nigeria’s built environment polytechnic undergraduates via a qualitative approach.
