Highway infrastructure and building information modelling in UK

Traditional methods of design are becoming less relevant and prevalent, due to institutionalising of building information modelling (BIM) within statutory regulations and the huge amount of data that BIM presents to practice; especially in 3D models. This can be seen in the A1 Dishforth-to-Barton road infrastructure improvement scheme which comprises the A1 Dishforth-to-Leeming and A1 Leeming-to-Barton schemes. The traditional method of design was central to the A1 Dishforth-to-Leeming scheme and BIM central to the A1 Leeming-to-Barton scheme. So this report presents a comparative study of the traditional and BIM methods in relation to the A1 Dishforth-to-Barton improvement scheme through the perception of key professionals involved in this project. A qualitative research study was conducted through the use of an open-ended questionnaire intended to bridge gaps in perceptions and understanding of both methods. Judgemental sampling technique was used to select experienced respondents who understand and participated in the A1 Dishforth-to-Barton road infrastructure improvement scheme. The study reveals an incontrovertible complementary nature of both methods and that the realisation of the 2016 mandate appears doubtful due to lack of standardization, training and level of awareness. It is highly recommended that a statutory incentivization framework for BIM be conceptualised and considered for implementation to attract and encourage small scale participants. Of high priority is the subsidization of in-house training by local authorities and localized joint ventures by smaller companies for specialist training.
