The purpose of this paper is to report on primary research findings that sought to investigate and analyse salient issues on the implementation of 5D building information modelling (BIM) from the UK contractors’ perspective. Previous research and efforts have predominantly focussed on the use of technologies for cost estimation and quantity takeoff within a more traditional-led procurement, with a paucity of research focussing on how 5D BIM could facilitate costing within contractor-led procurement. This study fills this current knowledge gap and enhances the understanding of the specific costing challenges faced by contractors in contractor-led projects, leading to the development of 5D framework for use in future projects.
To develop a fully detailed understanding of the challenges and issues being faced in this regard, a phenomenological, qualitative-based study was undertaken through interviews involving 21 participants from UK-wide construction organisations. A thematic data analytical process was applied to the data to derive key issues, and this was then used to inform the development of a 5D-BIM costing framework.
Multi-disciplinary findings reveal a range of issues faced by contractors when implementing 5D BIM. These exist at strategic, operational and technological levels which require addressing successful implementation of 5D BIM on contractor-led projects adhering to Level 2 BIM standards. These findings cut across the range of stakeholders on contractor-led projects. Ultimately, the findings suggest strong commitment and leadership from organisational management are required to facilitate cost savings and generate accurate cost information.
This study highlights key issues for any party seeking to effectively deploy 5D BIM on a contractor-led construction project. A considerable cultural shift towards automating and digitising cost functions virtually, stronger collaborative working relationship relative to costing in design development, construction practice, maintenance and operation is required.
By analysing findings from primary research data, the work concludes with the development of a 5D BIM costing framework to support contractor-led projects which can be implemented to ensure that 5D BIM is successfully implemented.

The purpose of this paper is to investigate the relationship between housing finance institutional related variables and financial related variables of low-income earners in Bauchi Local Government Area, Bauchi, Nigeria.
In this study, quantitative research approach was adopted. Self-administered structured questionnaires were used to collect information from 500 primary school teachers in Bauchi Local Government Area, Bauchi, Nigeria. A correlation analysis was carried out to find the relationship between housing finance institutional contexts and finance contexts to low-income earners in the study area using SPSS Version 23 software.
The findings shows that the low-income earners were more concerned with the accessibility and affordability on housing ownership, and it also showed that performance and effectiveness of the housing finance institutions were of paramount importance to housing ownership for the low-income earners in the study area.
The finance institutions are the prime consumer of these research findings. The participants in the finance institutions are going to benefit from the low-income earners’ housing ownership development.
The paper also emphasized that the finance institutions should make the housing finance loan accessible and affordable to the low-income earners to meet their dream to sustainable housing ownership.
