Highway infrastructure plays an important role in assuring the proper function of the nation’s transportation. Highway alignment is an essential part of the highway planning and design phase, which has significant effects on the surroundings. Identifying optimal highway routes while using traditional methods requires significant time, cost, and effort, since it requires a comprehensive assessment of multiple factors, such as cost and environmental impacts. This study proposes an approach for managing highway alignment in the context of a larger landscape that integrates building information modelling (BIM) and geographic information system (GIS) capabilities. To support this integration, semantic web technologies are used to integrate data on a semantic level. Moreover, the approach also uses genetic algorithms (GAs) for optimizing highway alignments. A fully automated model is developed that enables data interoperability between BIM and GIS systems and also allows for data exchange between the integration model and the optimization algorithm. The model enables the full exploitation of features of the project and its surroundings for highway alignment planning. The proposed model is also applied to a real highway project to validate its effectiveness. The visualization model of the highway project and its surroundings provides a realistic three-dimensional image that produces a comprehensive virtual environment, where the project could be effectively planned and designed. That can help to reduce design errors and miscommunication, which, in turn, reduces project risks. Moreover, geological and geographical analyses help to identify geohazards and environmentally sensitive regions. The proposed model facilitates highway alignment planning by providing a cross-disciplinary approach to close the gap between the infrastructural and geotechnical planning processes.

“…The importance of ensuring construction quality was also emphasised by Chew and Tan (2004) for improving the maintenance of wet areas. This seems to be significant given the current acute skills shortage in the industry fuelled by sustained regional growth, which contributes to the depletion of build quality (Dainty et al, 2004;Anumba et al, 2005). Though bathroom modules should have superior embedded quality than traditional in situ bathrooms as the modules are manufactured in factory-controlled conditions, the workmanship for their installation and repairs should be guaranteed.…”

Purpose -Offsite is one of the main innovative techniques employed in the contemporary UK construction sector. Building maintenance accounts for over 5% of the UK"s gross domestic product of which bathrooms are regarded as a critical area, with potential high risks and defects. However, the importance of its maintenance has been largely underestimated and research into this area appears to be limited. This paper aims to address this knowledge gap by investigating the maintenance performance of offsite and insitu bathrooms for student accommodation. Methodology/Approach -The paper examines 732 maintenance records over three years of 216 precast concrete modules, 84 Glass Reinforced Polyester (GRP) modules and 96 traditionally-built insitu bathrooms. Findings -The research found that offsite modules outperformed insitu bathrooms in terms of maintenance. GRP modules created the least maintenance problems, compared to precast modules and insitu bathrooms. The maintenance of insitu bathrooms was more complex than offsite modules, and involved more diverse problematic areas. The main causes of the problems included inappropriate design, poor build workmanship, lack of quality of component materials and improper usage by occupants. This supports a parallel study by the authors that found that the costs associated with maintenance were significantly higher for insitu bathrooms than for the equivalent offsite solutions. Research limitations/implications -The paper contributes to understanding the problems of offsite bathroom modules requiring maintenance in comparison with insitu bathrooms and their possible causes. Key aspects of offsite bathrooms including drainage, toilets, vents and sinks should be improved. Quality of component materials used for insitu bathrooms should be ensured. These improvements can only be achieved through better design for maintenance with clients" aspiration embodied. The findings should assist in design decision-making of selecting bathrooms for residential buildings. However, a balanced approach, taking into account other factors for such selection, is open for future investigation. Originality/Value -The framework of strategies developed should improve the innovative design of bathrooms manufactured offsite and help maintain them for better lifecycle performance.
