schedule, enabling interface issues to be highlighted more easily which would cost time and money if not picked up until on site.


“The use of Integrated Concurrent Engineering (ICE), where interdisciplinary reviews are conducted with a dynamic view of the design, schedule and cost, move 4D modelling from an output of the design process, to an input into design development – this is where it is most powerful and issues are picked up earlier in the process.”


Level 3 Advancing BIM to its highest level of maturity


– known as ‘Level 3’ – means project-wide approaches and common tools, and an incredible amount of integration [see below diagram and table]. We asked Kerbey whether this is realistic with something the scale of HS2, or whether it will be better imagined as a series of smaller ‘projects’ that each use BIM in their own ways.


He said: “Yes, HS2 is really a series of projects and if there is not a common data environment for all of these projects to operate within, then there is a greater risk of data duplication, data errors, interface issues, and ineffi cient information sharing and exchange. Again, it comes down to the premise


that technology is the easy bit. A robust IT infrastructure that is scalable to deal with the demand of the proposed future supply chain


increasingly complex, when you isolate


projects, is


is perfectly feasible. What becomes begin


to collaborative working


across disciplines – some of which may be route-wide – and across contracts.


“It


also becomes more onerous to control and assure information from a number of environments that are not project-wide and are not common HS2 tools, regardless of whether


you have robust standards and


procedures in place and instructed through the contracts.


“Another facet to this is that the concept of big milestone data deliveries is not feasible with a project the


size of HS2, therefore


iterative or phased deliveries will ensure that data can be assessed, decisions made and corrections made at the earliest opportunity. This promotes
