Fourth industrial revolution (4IR) technologies have been proved as successful platforms to communicate and visualise construction projects within team meetings. These techniques possibly can enhance compliance with Covid-19 rules on sites. How far concerning Nigerian construction contractors in the use of 4IR technologies are yet to receive in-depth studies. Therefore, this paper offers a collective insight into the issues affecting construction firms from Covid-19 regarding lockdown rules and the role of 4IR technologies. Given the unexplored nature of the problem, a virtual face-to-face type of qualitative research method was employed. Twelve semi-structured interviews from selected construction firms and consultant experts were engaged and collated data analysed via a thematic approach. Findings group the 4IR technologies into smart construction site, simulation and modelling, and digitisation and virtualisation in Nigeria’s context, and majority of the 4IR technologies can be useful to enhance Covid-19 compliance. Reluctant to adopt, high implementation cost, inadequate knowledge management, resistance to change, among others emerged as the factors hindering 4IR technologies usage. Findings will strengthen and provide a rich insight into the impact of Covid-19 on construction sites and contribute towards informing key stakeholders to create an enabling environment for the implementation of 4IR technologies on site.

第四次工业革命 (4IR) 技术已被证明是在团队会议中交流和可视化建设项目的成功平台。这些技术可能会增强网站对 Covid-19 规则的遵守。尼日利亚建筑承包商在多大程度上使用 4IR 技术还有待深入研究。因此，本文就锁定规则和 4IR 技术的作用对 Covid-19 影响建筑公司的问题提供了集体见解。鉴于问题的未探索性质，采用了虚拟的面对面类型的定性研究方法。对选定的建筑公司和顾问专家进行了 12 次半结构化访谈，并通过主题方法对数据进行了整理分析。调查结果将 4IR 技术分为智能建筑工地、模拟和建模以及尼日利亚背景下的数字化和虚拟化，大多数 4IR 技术可用于增强 Covid-19 合规性。不愿采用、高实施成本、知识管理不足、抵制变革等成为阻碍 4IR 技术使用的因素。调查结果将加强并深入了解 Covid-19 对建筑工地的影响，并有助于告知主要利益相关者为现场实施 4IR 技术创造有利环境。实施成本高、知识管理不充分、变革阻力等成为阻碍 4IR 技术使用的因素。调查结果将加强并深入了解 Covid-19 对建筑工地的影响，并有助于告知主要利益相关者为现场实施 4IR 技术创造有利环境。实施成本高、知识管理不充分、变革阻力等成为阻碍 4IR 技术使用的因素。调查结果将加强并深入了解 Covid-19 对建筑工地的影响，并有助于告知主要利益相关者为现场实施 4IR 技术创造有利环境。
