Glasgow firm Bird Semple has lost its second department head this year following leading construction partner Lindy Patterson's decision to move to MacRoberts. Patterson (right) takes her team of two lawyers from the Edinburgh office of Bird Semple to Edinburgh-based MacRoberts, where she will take the role of partner alongside a team of five other construction lawyers. Patterson has been replaced as head of construction and engineering at Bird Semple by Fenella Mason, who has been a partner with the firm for two years. Patterson's move follows Graham Sibbald's, who left Bird Semple in May to join Dundas & Wilson.
