Purpose This paper aims to develop a framework for optimising building performance through the integration between risk management (RM) and building information modelling (BIM) during the design process. Design/methodology/approach To achieve this aim, a research strategy consisting of literature review, case studies and survey questionnaire is designed to accomplish four objectives. First, to examine the concepts of design process, building performance, RM and BIM; second, to present three case studies to explain the role of using RM and BIM capabilities towards optimising building performance; third, to investigate the perception and application of architectural design firms in Egypt towards the role of RM and BIM for enhancing building performance during the design process; and finally, to develop a framework integrating RM and BIM during the design process as an approach for optimising building performance. Findings Through literature review, the research identified 18 risks that hamper optimising building performance during the design process. In addition, 11 building performance values and 20 BIM technologies were defined. Results of data analysis showed that “Design budget overrun”, “Lack of considering life cycle cost” and “Inefficient use of the design time” were ranked the highest risks that affect the optimisation of building performance. Respondents ranked “Risk avoid” or “Risk transfer” as the most risk responses adopted in the Egyptian context. In addition, “BIM As Built” was ranked the highest BIM technology used for overcoming risks during the design process. These findings necessitated taking action towards developing a framework to optimising building performance. Originality/value The research identified the risks that affect optimising building performance during the design process. It focuses on improving the design process through using the capabilities of BIM technologies towards overcoming these risks during the design process. The proposed framework which integrates RM and BIM represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

Achieving sustainability in construction projects is becoming an increasing priority worldwide. Being one of the crucial phases of the construction process, the design process plays a major role in achieving the goals of sustainability. Adopting innovative design solutions is a promising way of enhancing the sustainable performance of buildings. However, the implementation of innovative solutions is risky and needs to be managed carefully to avoid failure. Due to the increasing number of construction projects being developed in Egypt and because of the need to achieve the Sustainable Development Strategy (SDS) 2030, adopting innovative solutions became an essence. Accordingly, this research aims to investigate the risks associated with innovative solutions during the design process. In order to achieve this aim, a research methodology consisted of literature review and case studies was designed to achieve three objectives. First, to build a comprehensive background about the research topic including the concepts of sustainability, innovation and innovation risks, and the design process. Second, depict the relationship between innovation risks, the architectural innovation aspects, architectural design process and sustainability aspects. Final, present and analyze three case studies to explore the innovation management strategies adopted to overcome the risks associated with the adopted innovation solution.

Despite the social and economic contributions of the construction industry towards achieving sustainable development objectives, it has an adverse effect on the environment such as the generation of waste, water, and energy consumption. Construction waste (CW) is the loss of materials that are produced during or after the construction process and has no remaining value. Several countries promote waste elimination plans at early stages to reduce CW at its source. The Egyptian government is expanding its investments in new mega projects and infrastructure facilities like new administrative capital, bridges, roads, energy projects which resulted in increasing the rate and amount of generated CW. The literature review stated that 33% of CW generated in the primary design stage is the result of design flaws such as design errors and lack of waste management strategies used during the design process. Accordingly, this research aims to investigate the factors influencing CW generation during the design process. To achieve this aim, the development of proper research methodology took place, where it consisted of qualitative analysis of previously published literature and examining case studies to accomplish two objectives. Firstly, an investigation of previous literature focused on studying the design process, CW, and the global and national waste management strategies. Secondly, three case studies were introduced and analysed to study the role of design out waste strategies towards reducing CW during the design process.
