This document provides an overview of the strategy, execution, and delivery processes for a Building Information Modeling (BIM) project to construct a new road link in Bedfordshire, England. It discusses developing an Employers Information Requirement document according to British standards to outline the project requirements. It also describes releasing an invitation to tender requiring BIM compliance and submitting a pre-contract BIM Execution Plan as part of the bidding process. Finally, it discusses setting up a Master Information Delivery Plan including a construction program and model production tasks once a contractor is selected.
BIM allows for improved analysis, modeling of a building's lifecycle, and new design capabilities. It facilitates collaboration between project stakeholders and leads to better quality construction with reduced time. Integrated Project Delivery is identified as having the most potential for BIM use by utilizing BIM, effective collaboration, and early trade integration. BIM provides advantages over traditional models through preconstruction benefits to owners, improved design processes, construction/fabrication benefits, and post-construction facility management benefits.

Sue Holmes, Director of Estates and Facilities Management at Oxford Brookes University, delivered an engaging keynote on Estate quality and how it is is linked to student choice and expectations. This session explored the issues and challenges of defining and delivering a transformational estate. How do we ensure that spaces provide a forty year building life, meet immediate needs, but are flexible enough in many cases, to meet future and as yet undefined need? Transformational spaces require transformational concepts and ideas that many colleagues will then need to articulate and deliver.
Whether providing new space or refurbishing existing spaces, for teaching, research, or residential needs, estates projects always have a significant impact on users, our campus community and inevitably our local area. With challenging legislative compliance and a need to ensure we manage future operational costs, transforming our estate reaches far and deep.
Case study: Melbourne Business School closes the loopLeaMaguero
Melbourne Business School (MBS) teamed up with BioPak to replace disposable plastic foodservice packaging with compostable bioplastic alternatives in order to reduce waste and negative environmental impacts. MBS recognized that single-use plastic could not be fully eliminated from on-campus food outlets. By switching to BioPak's compostable packaging and compost collection service, MBS has been able to divert between 2,000-3,000 kilograms of compostable waste from landfills each month. This avoids methane emissions from landfills and removes non-recyclable plastic waste.
Development of Energy Efficient kitchen in the case of AMU main campusbereket bekele
The document proposes developing an energy efficient kitchen for the student cafeteria at Arba Minch University's main campus. Currently, the kitchens are temporary, lack proper sanitation and HVAC systems, and use traditional cooking methods that waste energy. The project aims to improve food safety, worker productivity and efficiency, and reduce energy consumption through better kitchen design. It will analyze the existing spaces and issues, then provide architectural solutions like improved systems, appliances, and adoption of new technologies to create efficient, safe and high quality food preparation areas. The efficient kitchen design would benefit workers and users by enhancing hygiene standards and energy savings.

In human communication, explanations serve to increase understanding, overcome communication barriers, and build trust. They are, in most cases, dialogues. In computer science, AI explanations (“XAI”) map how an AI system expresses underlying logic, algorithmic processing, and data sources that make up its outputs. One-way communication.
How do we craft designs that "explain" concepts and respond to users’ intent? Can AI identify, elicit and apply relevant user contexts, to help us understand AI outputs? How do explanations become two-way?
We must create experiences with systems that will be required to respect user needs and dynamically explain logic and seek understanding. This is a significant challenge that, at its heart, needs UX leadership. The safety, trust, and understandability of systems we design hinge on the way we craft models for explanation.
