This Practice Note provides guidance on expert evidence in the Technology and Construction Court (TCC) under CPR 60, CPR PD 60 and Technology and Construction Court Guide, para 14.1 onwards. In particular, it considers the relevance of experts in TCC claims, the experts’ duties, case and cost managing expert evidence (including pursuant to CPR 35.4 of the CPR), single joint experts (SJEs), experts’ meetings, experts’ joint statements, experts’ reports and the giving of expert evidence at trial whether concurrently (through ‘hot-tubbing’) or in the more traditional adversarial way. Finally, the consequences of failing to comply with expert obligations are considered along with practical tips on expert evidence in the TCC. Note: • shorter and flexible trials schemes—claims started on or after 1 October 2015 in the TCC may be suitable for and/or be subject to one or both of the schemes operating under CPR PD 57AB, namely the shorter trials scheme and/or the flexible trials scheme. For more information on these schemes, see Practice Notes: Business and Property Division—shorter trials scheme and Business and Property Division—flexible trials scheme
