About information delivery planning
4.4.3.2 Dependencies and predecessors
To agree delivery milestones and production
durations, as required by ISO 19650 and
as noted in section 4.4.1, the task team and
lead appointed party must be aware of other
dependency and predecessor information
agreed with other task teams.
Figure 11 (a and b) illustrates two ways in
which a dependency can be recorded in a
TIDP. In Figure 11a (tabulated format), the
“piling task team” identied that architectural
site information was required but did not
note when they would receive the information.
The Gantt chart example (Figure 11b)
also indicates a dependency on a specic
architectural deliverable, but in addition shows
the date it will be received. This indicates that
the “piling task team” either:
• Coordinated with the lead appointed party
to conrm a delivery date, or
• Highlighted via a placeholder in their
programme, when they needed the
information to arrive.
This shows they have allowed ve days for
review before sharing their rst piling layout
plan.
4.4.3.3 Level of information need
ISO 19650-2 clause 5.4.4 states that the TIDP
must also record level of information need for
each information container. The purpose of
this is to dene the scope of contents of the
information container.
One example could be in relation to a piling
layout, as illustrated in Figure 11b, whereby the
pile types are a mandatory prerequisite of the
issue, potentially determined by the exchange
information requirements (EIR) that formed
part of the author’s piling requirements.
Another example could be in reference to a
door schedule, whereby the author denes
the scope of the door schedule key contents
at the point of issue, which may include “Fire
Ratings”. Another common example could be
in relation to an equipment schedule used
in operation and maintenance submittals.
The TIDP may reference a specication that
denes the contents.
The primary benet for the task team in
dening the level of information need in the
TIDP is to make it clear what will and will not
be included within the information container
at its various milestones.
4.4.3.4 Production durations
It is important to identify information
production duration in the TIDP. This is
particularly relevant if there are dependencies,
such as information that is needed from, or
by, another task team or allowing for a review
period.
4.4.3.5 Author
There are a few ways to approach the
“information author” content in the TIDP.
• Depending on the organizational structure
of the task team or the approach to the
TIDP, it may be sucient to dene the
whole authoring organization as the key
author for all deliverables
• If a task team has a complex structure,
for example, it has two distinct disciplines,
it may be pragmatic to list the discipline
leads specically
• If the TIDP contains listed dependencies
from other task teams, it may be advisable
to list these under a dedicated author, as
illustrated in Figure 11b.
4.4.3.6 Milestones
It is important to consider all milestones when
producing the TIDP. Milestones include those
identied in the appointment EIR, as well
as those determined by the task team. A
milestone could be based on the purpose for
issue such as, for comment with status S3 or
when published within stage 4 with the status
A4.
4.4.4 Appointment signicance
ISO 19650-2 clause 5.4.7 requires that each
appointed party appointment includes the
relevant TIDP(s) – see ISO 19650 guidance
part 2 sections 1.4 and 1.5. This ensures a
contractual obligation to deliver the required
information. Updates to the TIDP following
appointment should comply with agreed
change control procedures.
