The PAS1192:2 Roles

In the UK, PAS1192:2 suitably notes the distinct roles that are to be absorbed by existing project individuals regardless of their job title. A necessary step to allow for the variance in name as frequently encountered by differing project members from one company to the next.

These “new roles” do seem to compound the problem of clarification however, as job titles may well mean different things at different company levels (Director, Manager etc) but the PAS1192:2 role of Task Team Manager and Interface Manager and the like have seemingly been embraced by an industry that has taken to using a suite of “BIM” roles instead.

This makes the mapping of the obvious parallels in these roles much more difficult. So much so that it could be argued by some that this exercise need to be done, but current trends (and especially a glance at the jobs market) suggests otherwise and opinion and confusion seems to run rife. PAS1192:2 is a homegrown standard for sure, but BIM is global.

What is more, the BIM Coordinator role is also prone to meandering too, depending on whether or not the individual originates on the design side or the construction side of the operation. As if it wasn’t difficult enough.

We need to unpick this entirely by again translating these roles into their respective duties, and then piecing the jigsaw back together. To do this, we will look at key documentation that the many roles are exposed to, and explore exactly where these roles fit in and how they complement each other from there.

Creating the Master Information Delivery Plan (MIDP)

Once the contract has been awarded, the MIDP lists the information deliverables for the entire project - as prepared by the supplier/s in order to honour the project information clarified in the Employer’s Information Requirements (EIRs).

As such, the MIDP is developed with reference to each team’s Task Information Delivery Plan (TIDP) so submitted by all relevant teams. In short, the TIDPs are the granular documents that are then assembled to create the overall MIDP.

As the milestones taken from the overall design and construction programme are used to align the TIDPs in the first place, the TIDP also indicates the team members responsible for specific tasks, as well as capturing how the responsibility of the preparation of project documentation is to transfer among these very teams themselves. These TIDPs can then be assembled overall into the MIDP. The “CPIx Post Contract Award BEP” contains a suitable TIDP template to use.

Using PAS1192:2 language, the TIDPs are prepared by so called Task Team Managers, so assisted by, and dependent upon, Task Information Managers, Interface Managers and BIM Authors[7].

Using BIM parlance then, it must be remembered that a supplier’s own BIM Managers and BIM Coordinators would need to ensure that they and their teams are aware of, and aligned with, the overall project milestones in the MIDP - not just their own TIDP milestones as other tasks can be affected by delay if monitoring and reviewing is not carried out sufficiently[20].

Teams will also need to produce and police their own Volume strategies as well - which in short look at how large projects may be split into smaller sections usually by building name, grid line, specific area or the like such that the data becomes more manageable and easier to distribute and use. So teams have a lot to think about and the person heading the team especially so.

What are Task Teams exactly?

The term used in the above context is certainly broad and can fall to any project participant group. As PAS1192:2 notes, task teams could be split into Architectural Task Teams, Structural Task Teams or for Infrastructure project; Rail or Road Task Teams, Station Task Teams, Bridge Task Teams and so on[7]. So any cohort of individuals, typically in a design discipline or capacity, tend to be what is being referred to.

PAS1192:2 - Information Originator

This role is so tasked to develop parts of the Information Model as designated by that specific task and to produce project outputs and the like thereafter. Taking ownership of model information also features[7] and these duties naturally chime well with those of the BIM Modeller or BIM Author. Although the latter could include model analysis and subsequent  documentation as well. But not a person who has written a book about BIM, tongue firmly in cheek.

PAS1192:2 - Interface Manager

So tasked to manage spatial coordination on behalf of the task team as well as proposing resolutions to coordination clashes as well[7]. This naturally lends itself to being undertaken by a BIM Coordinator especially in a multidisciplinary practice[11}.

PAS1192:2 - Task Information Manager

As mentioned previously, specific duties include the ability to direct the production of the task information in compliance with the existing project standards, methods and procedures.  An ability to review information that has been clash detected and confirm that is is suitable for issue within the CDE also features[7]. These duties distinctly seem to fit those of a BIM Coordinator.

PAS1192:2 - Task Team Manager

Note the use of “Team” in the title here rather than “Information”. At first suggesting a supplier’s BIM Manager would absorb these duties. Yet parallels are felt within the BIM Coordinator role as well because the Task Team Manager duties seemingly include the production of design outputs related to a discipline specific package, before issuing this information to the CDE-  rather than merely confirming that the information is suitable for issue to the CDE. Naturally the size and scale of the project will determine who exactly carries this out but predictably these roles often tend to be combined, as John Adams (BIM Strategy) notes.


In general the Task Team Manager/ Task Information Manager is a single role in each business that has produced a TIDP. In an architectural practice this is one of the seniors who is suitably experienced to sign off drawings in a QA process before delivery.  The same goes at structural and M&E offices.   

Obviously these individuals need to do some learning to be able to sign off COBie deliverables and model exchanges, but let’s face it they are seniors and they have to take responsibility for what leaves the office at the end of the day regardless.  

I have learned that this is currently a missing element on projects, as the seniors are deferring this responsibility to junior members of the team who can drive the tools, leading to inappropriate models and poorly structured data polluting their projects.  

Where BIM hits ISO 9001 is an issue for many offices at the moment.[4]



The Task Team Manager best suits a Design Team Lead or an Operational Discipline Lead such as a Section or Area Project Manager or Contract Manager when it comes to MEP, Architectural and Structural disciplines.

Alternatively, for a rail project the Contractor’s Responsible Engineer (CRE) for Track, Signalling & Telecommunication (S&T), Electrical and Power (E&P), Overhead Line Equipment (OLE) and so on would perhaps be best suited to absorb the role.

The Task Information Manager however is more of an assurance role – assuring capability of the team to produce information in line with the standard methods and procedures (SMP) – provide education to the Task Team on these SMPs, and assuring the information produced by the team is in line with the SMPs before sharing.  This position for me is a “critical friend” role – basically an internal checkpoint within the Task Team to make sure that any information produced is correct before it is shared with the rest of the project or other task teams. Depending on the type and size of the project – it could be a lead engineer sitting under the discipline lead perhaps.[5]



I would say at present the Lead Designer from each discipline tends to be seen as a Task Team Manager, with the Task Information Manager policing each disciplines CDE usage.

With the Interface Manager being a role in a multi-disciplinary practice charged with ensuring that models are coordinated and clash detected before they are issued to the CDE, perhaps. But all of these roles are used quite loosely at present.[11]
