It is with great sadness that we announce the passing of our dear friend and colleague Alan Mack. We were privileged to have worked with him and he will be fondly remembered for his work within the construction industry and support to Constructionarium, but more importantly for being a charismatic and fair man who saw through work to the more important matters in life. He was very popular with the students, who benefited from his wealth of experience and mentoring during our Constructionarium weeks. He will be sadly missed by all who had the pleasure of meeting him. Our thoughts and condolences go out to his family in these difficult times.
