Abstract

Purpose – Building project delays in Lagos State average over 40% beyond scheduled completion, yet the relationship between modern construction technology (MCT) adoption and time performance remains empirically underexplored in the Nigerian context. This study, therefore, investigates the extent to which the adoption of modern construction technologies influences the time performance of building projects in Lagos State, Nigeria.

Findings – Construction firms exhibited significant adoption of BIM and mobile technologies, but critically low usage of IoT, RFID, AR/VR, and 3D printing. A strong positive correlation was observed between technology adoption and improved time performance (r = 0.553, p < 0.05), crucially demonstrating that adoption of data-centric MCTs across interconnected phases offers the most significant leverage for improving project delivery time. Executionphase technologies alone showed no significant correlation with timeliness.

Research limitations/implications – The study focused on Lagos State, limiting generalisation to other regions. Future research could explore longitudinal impacts of technology adoption across diverse geographic contexts.

Practical implications – The findings emphasise the need for government incentives, skill development programs, and standardise regulations to accelerate technology integration. Stakeholders should prioritise integrated deployment of data-centric technologies (including BIM and mobile tools) to significantly enhance time performance and reduce project delays.

Originality/value – This study uniquely links technology adoption to time efficiency in Lagos state’ construction sector, addressing a critical gap in developing economies. It provides actionable strategies to enhance project resilience, safety, and economic outcomes in rapidly urbanising regions.

Mariam A. Oluwatosin, Micheal Adebamowo — Sun, 10 May 2026 00:00:00 +0000

Abstract
Purpose: This study investigates levels of awareness and adoption of sustainability and innovative technology strategies among architects practicing in high-rise building design in Lagos, Nigeria. The aim is to determine the way these experts integrate sustainable practices and technologies as a mitigation measure for the growing need for environmentally responsive urban development.

Design/Methodology/Approach: A mixed-method approach was used in the study. 87 responses were received from the semi-structured questionnaire shared with registered architects in Lagos. The Statistical Package for the Social Sciences version 23 was used to analyse the data, using both descriptive and inferential statistical methods. The interpretation of the quantitative results was also supported by thematic analysis of the qualitative observations obtained from the semi-structured responses.

Findings: There is high awareness among Lagos architects of both technological and sustainable initiatives, but uneven adoption. The most widely applied are daylighting and natural ventilation, while more sophisticated strategies such as BIM, modular construction, and green roofs have lower adoption. The findings show awareness-adoption imbalance, with a need for ways to balance it to align practice with global sustainability ambitions.

Conclusion/Theoretical/Social/Practical Implications: Inadequate policies, lack of technical skill, as well as high cost are some of the main gaps to the adoption of sustainability and innovative technology strategies. To close this gap, professional development and government interventions are needed to align sustainable design strategies with SDGs 11 and 13.

Originality and value: The empirical findings and interpretation offer a basis for comparative
studies in other regions and specific frameworks to improve adoption.

Emmanuel M. Rotimi, Fidelis O. Achi, Israel E. Oseyomon, Chinonso D. Agoha — Sun, 10 May 2026 19:36:56 +0000

Abstract
Purpose – Submission of pre-construction documentation is central to building control and a prerequisite for regulatory approval, yet compliance level varies widely across the industry. In Lagos State, inconsistent submission patterns raise concerns about procedural adherence and regulatory effectiveness. This study evaluates construction professionals’ perceptions of compliance with required documentation and variations by professional role, years of experience, and educational qualification. It is framed by regulatory enforcement theory and professional practice perspectives, which emphasise that compliance is shaped by institutional oversight and role-based exposure.

Design/methodology/approach – A quantitative design was adopted. From 309 questionnaires distributed among registered professionals in construction firms operating within Lagos State, 288 valid responses were analysed. Descriptive statistics and the Kruskal–Wallis test were applied. Documents were grouped into legal, technical, and regulatory categories to assess compliance levels.

Findings – Compliance level varied across categories. Technical documents such as architectural drawings and structural designs were more consistently submitted than legal (e.g., land title) and regulatory documents (e.g., Environmental Impact Assessment). Compliance also differed significantly by profession and years of experience but not by educational qualification.

Conclusion/Theoretical/Social/Practical implications – The results support regulatory enforcement and professional practice theories, showing that compliance is shaped more by institutional processes and practical experience than academic training. Practical implications include digital submission platforms, standardised checklists, stronger enforcement, and compliance-focused professional training.

Originality/value – This study empirically assesses pre-construction documentation compliance in Lagos State within broader compliance theories and provides evidence-based insights to strengthen Nigeria’s regulatory framework and reduce risks of building collapse.

Abstract
Purpose: The Internet of Things (IoT) is a groundbreaking development that has a big impact on many industries, including real estate. In the past, traditional methods and manual procedures have been the main drivers of property management, building, and urban planning. However, the emergence of IoT technology has led to a shift in the way real estate is constructed, maintained, and managed, particularly in developed nations. This paper, therefore, examined the perspectives of estate surveyors and valuers (ESVs) in Lagos State on the benefits and challenges of adopting IoT in the real estate profession.

Design: A quantitative survey was conducted using structured questionnaires administered to 184 estate surveyors and valuers (ESVs) in Lagos State, Nigeria. Percentages, mean, relative importance index (RII), and factor analysis were used to analyse the data.

Research limitations and implications: This study is limited to ESVs in Lagos State, Nigeria. Future research could explore the views of other built-environment professionals in Lagos State or ESVs across different regions.

Findings: The study found the benefits of IoT in real estate practice to be data-driven decision-making, efficient property management, and condition monitoring for preventive maintenance. Some of the challenges identified were the high cost of implementing IoT infrastructure,
concerns about data security and privacy, and a lack of technical expertise among real estate
professionals.

Conclusion, Practical and Theoretical Implications: The study offers practical implications
for policymakers, real estate professionals, and academia by identifying key benefits and
challenges to the adoption of IoT in the real estate industry. These insights are especially
relevant for sustainable real estate development.

Indoor Air Quality (PM2.5, PM10 and CO2) in Academic Lecture Theatre in University of Lagos, Nigeria

Sun, 10 May 2026 20:34:55 +0000

Abstract
Purpose – The purpose of this study is to investigate the indoor air quality within a lecture theatre at University of Lagos, Nigeria. With a view to providing credible data for IAQ management and awareness on the effects of indoor air pollutants to occupants.

Method – Quantitative research method was adopted for this study. The research design was a combination of field measurement and a survey design approach (through questionnaire). The study was conducted in Faculty of Engineering lecture theatre (ELT). ELT was selected due to it, being frequently used by a large number of students for lectures. Major considerations for this study are concentrations of CO2, PM2.5 and PM10, temperature and humidity within the building. The data collection instruments were portable handheld air quality monitors, a checklist and a structured air quality questionnaire. This study used time series analysis, relative important index (RII), and equation for data analyse.

Result – The result shows that the average indoor PM2.5, PM10 and CO2 over 24 hours monitoring at ELT are 17 µg/m³, 28 µg/m³ and 982 pmm respectively. The indoor PM2.5 was higher than WHO benchmark while indoor CO2 was marginally lower than WHO recommendation. Indoor AQI at ELT is 61 (Level 2). Feeling of discomfort (too hot) arose at about 50 % capacity of the theatre with symptoms such as loss of concentration, irritated eye and sweatiness.

Research Limitation – The study focused on ELT, which is a lecture theatre in Faculty of Engineering and did not consider other classrooms in the Faculty.

Conclusion, practical and theoretical implications – The study therefore concludes that the
indoor air quality at ELT is poor due to high level of pollutants present. This study brings to
fore the pattern of air contaminants at ELT and the need for adequate measures to curtail it.
