Improving Safety on Building Project Sites: The Role of Sensor-Based Technology

Sensor-based technology (SBT) is a new method of advancing construction safety management. The technology may abate the scourge of accidents on sites and improve workplace safety performance in construction. Research about Nigerian construction contractors/property developers’ use of SBT is yet to receive in-depth studies. Thus, the study investigated the perceived encumbrances facing the implementation and recommended possible measures to improve safety by promoting SBT in Nigerian building project sites. The study adopted an interview type of qualitative research design and was complemented with eight construction sites observation to achieve the aim. The researchers engaged twenty-four participants (selected safety experts, property developers/building companies, and construction consultants). The paper adopted a thematic approach to analyse the collected data. Findings show that SBT usage is low across the eight construction sites studied. Three sub-themes (management, technical, and financial encumbrances) emerged from SBT usage issues. The study recommended feasible measures to improve SBT across high-rise Nigerian construction sites. Results from the study will strengthen and offer an insight into SBT on building sites. It would enlighten major industry practitioners (property developers and construction contracting firms) and policymakers to create an enabling platform for SBT improvement on construction sites.
