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.

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

Covid-19 pandemic have raised serious health concerns, work disruptions and job loss. Thus, Nigeria’s Covid-19 challenges can hinder project performance in the construction sector. By integrating the principle of sustainable construction, it can minimise the environmental and socio-economic impact of Covid-19. This research therefore aims at developing strategies to achieve sustainable project performance in the post-Covid era in Nigeria.

A qualitative research method was used. Data was collected from 13 stakeholders in the built environment. Percentages and thematic analysis were used to analyse data from the interviews.

The study reveals that stakeholders are encountering operational and financial challenges: Increased price of materials, labour and material shortage and project delays were key operational challenges. The financial challenges were related to increased construction cost, reduced profit and payment delays. To address these challenges, the study developed managerial, contractual and governmental strategies: Market survey and bulk purchase, remote working and adherence to Covid-19 protocols were among the key managerial strategies. For the contractual strategies: contracts reviews, smart contracts, working overtime and night shift were developed, while governmental strategies included provision of funds, loans and incentives for workers.

The study deduced that while environmental sustainability was employed to address the Covid-19 challenges, the economic and social aspects were found to be under-utilized. Therefore, the study concluded that a holistic application of environmental, economic and social sustainability themes while incorporating managerial, contractual and governmental strategies is significant for achieving sustainable project performance in the post-Covid era in Nigeria.

The purpose of this study is to investigate the challenges of pricing quantity surveying (QS) professional services to enhance the understanding of practitioners in developing strategies for the determination of fees for their services.

The paper adopts the quantitative approach by administering 150 survey questionnaires QS professionals out of which 79 questionnaires were retrieved for analysis using the mean, standard deviation, standard error and the Chi-Square test.

The study identified the challenges that continue to hamper the successful pricing of QS services as the inability to respond to changing contractual arrangements; lack of appropriate response to emerging services; slow response to changes in information and communication technology.

This paper focused on QS professionals. Hence, a future study to encompass other professionals in the built environment will be novel.

The findings of this paper have the potential to motivate QS firms to develop solutions that address the challenges identified to improve the efficiency of their service delivery to clients. The paper also has the practical importance of opening up new frontiers of research that focus on pricing of professional services in the built environment in general.

The paper contributes to the awareness and understanding of QS professionals about the challenges that continue to hamper effective pricing of their services.

This study aims to review recent advances towards the implementation of ANN and NLP applications during the budgeting phase of the construction process. During this phase, construction companies must assess the scope of each task and map the client’s expectations to an internal database of tasks, resources and costs. Quantity surveyors carry out this assessment manually with little to no computer aid, within very austere time constraints, even though these results determine the company’s bid quality and are contractually binding.

This paper seeks to compile applications of machine learning (ML) and natural language processing in the architectural engineering and construction sector to find which methodologies can assist this assessment. The paper carries out a systematic literature review, following the preferred reporting items for systematic reviews and meta-analyses guidelines, to survey the main scientific contributions within the topic of text classification (TC) for budgeting in construction.

This work concludes that it is necessary to develop data sets that represent the variety of tasks in construction, achieve higher accuracy algorithms, widen the scope of their application and reduce the need for expert validation of the results. Although full automation is not within reach in the short term, TC algorithms can provide helpful support tools.

Given the increasing interest in ML for construction and recent developments, the findings disclosed in this paper contribute to the body of knowledge, provide a more automated perspective on budgeting in construction and break ground for further implementation of text-based ML in budgeting for construction.

Several researchers in the construction industry have mentioned that quality of tender documents is declining without tangibly assessing quality. Similarly, in practice, no standardised instrument exists to assess tender document quality. Therefore, the aim of this paper was to develop a framework to assess the quality of tender documents produced by built environment professionals in the construction industry. A framework was chosen to address the gaps in theory and practice as it provides a flexible but structured mechanism to assess tender document quality.

The research methodology contained three stages, namely: multi-investigator triangulation, a workshop with infrastructure experts and framework development and validation. A consolidated list of key quality indicators was developed following the literature review and multi-investigator triangulation. The indicators were discussed with ten experts in the South African construction industry, who were responsible for validating and providing insight on whether additional indicators were required. This informed development of the framework.

This paper proposes a framework to assess tender document quality by evaluating six key quality indicators namely: accuracy, clarity, completeness, standardisation, relevance and certainty.

The framework is limited to the assessment of tender document quality in the construction industry and is suited to the “Design by Employer” contracting strategy. From an academic perspective, this paper provides researchers with a framework to measure and benchmark quality of tender documents in future studies.

This framework can be used by clients to continuously assess and benchmark quality of tender documents produced by professionals.

A comprehensive and standardised approach to assess tender document quality was not available in the construction literature or the construction industry. Therefore, this paper addressed this gap in knowledge, by providing consumers (clients and contractors) of tender documents and researchers a mechanism to assess quality.
