The UK government’s mandate of BIM Level Two since April 2016 in the Architecture, Engineering, and Construction (AEC) industry meant that companies need clear standards and a road map for BIM implementation, especially in terms of standards. Now the UK government is looking to start implementing BIM Level Three, which is mentioned in the Government Construction Strategy 2016–2020, March 2016. Therefore, the AEC industry needs clearer standards to go further than BIM Level Two and to start the implementation of BIM Level Three. In infrastructure and civil works, where the gap between the industry and BIM is wider than in the building environment, having clear standards covered by direct road maps and platforms is essential. This paper challenges the fitness for purpose of the current specification and standards for infrastructure areas and civil works. It will be argued that the transfer of information and processes between site works and building, in general, is not yet clear, which might complicate the implementation process; in the sense that to facilitate the implementation process in infrastructure projects, the standards might be included in the file data properties which could help all stakeholders to work in various level of detail (LOD) specifications. This paper will be considered as a contributed paper, mainly built on a comprehensive review for LOD standards for sites, land development, civil works and file-format concepts under the specific guidance for the information management requirements associated with projects delivered using PAS 1192-2; the paper will also be shared in some of the management and technical interviews with project managers and BIM coordinators from the Gulf regain project’s experiences as part of the primary data. To be more practical, the paper will share a prototype of land development project developed in Muller Road, Bristol, UK, to be introduced using a visual information chart, showing the file format for the land development project’s information life cycle in detail, concept design projects and the capability of current BIM platforms to help engineers to go further.
