Abstract:
The temporary site offices are directly provided by the contractor, and hence, any
associated risk is non-transferable. Thus, the contractors should be aware of
sustainable, and cost-effective technologies to be implemented to survive in the
competitive construction industry. Relocatable Modular Building (RMB) technology is
employed globally as a multi-beneficial building technology for temporary shelter
purposes such as site offices. Hence, the research aimed to explore the applicability of
RMB technology for temporary offices on construction sites in Sri Lanka. The literature
synthesis reviewed the modular building concept and RMB technology globally.
Following the qualitative approach, the research adopted a survey strategy. Data was
collected through seven semi-structured interviews with industry professionals who were
purposively selected under several criteria. Further, data collection was limited to
container-based RMBs due to the limited availability of RMB varieties in Sri Lanka.
Template analysis was the data analysis technique followed. The findings disclosed that
RMBs have already been established in the Sri Lankan construction industry.
‘Relocatability’, reusability, high security, larger usable space within limited land
space, ability to rent out, and air-conditioned working environment were found as key
benefits of RMBs whereas the unbreathable smell of glue in newly fabricated RMB,
handling difficulties, the possibility of overturning, initial cost and external body
corrosion were identified as key challenges. Significantly, the contractors are
recommended to use RMBs for temporary site offices following proposed strategies such
as periodic maintenance procedures, systematic site administration, and safety
improvements to overcome identified challenges.
