J. Wyndham Prince wins 12d Model Customisation Award
J. Wyndham Prince is a leading civil engineering and project management
consultancy, originally founded in 1989. It has been planning, designing,
managing and delivering innovative land development projects in the Greater
Sydney region for over 35 years.
As a multidisciplinary consultant, it provides land developers and government
clients with a range of services from strategic engineering and planning advice
to project management and civil engineering design. J. Wyndham Price also offers
specialist services in roads and traffic infrastructure, storm water and
J. Wyndham Prince was involved in a number of subdivisions, where the lot
numbers seemed to always get larger, with one being an 1800 lot subdivision.
There were increasing numbers of kerb returns and roads. For each of these, a
designer would have to generate their own kerb return strings and apply them for
every individual instance.
“The workflow was essentially that the users would
have to generate their own kerb return strings, run the Apply Many on each of
those kerb return strings as well as the roads, build a surface, set up the
chains, and plot out the PPFs,” explains David Healy, (then) Engineer, J.
The model setup was redundant and tedious for the team. They wanted to find
something to lessen the burden of this repetitive work, so they could spend more
time designing rather than setting up models.
"The main problem we have as
designers is the initial setup process. Defining kerb returns, applying the
MTFs, it takes a lot of time, it's boring and it's tedious and designers don't
like doing it. It's incredibly inefficient and time-wasting for J. Wyndham
Prince. For example, one project had 109 roads and 426 kerb returns that had to
be done one at a time. It's not the most fun day," David says.
David and his colleagues created a macro in 12d Model that could automate the
lengthy process of doing kerb returns manually. The initial macro was fairly
simple, involving kerb returns and plotting. Over a five-year period they
continued to refine and enhance it, adding extra functionality, including
snippets, and global parameters.
"We worked out that we could hook those snippets up to the project attributes
and we took advantage of that to take it to another level. The workflow now
enables us to go from only graded centrelines to a built model complete with
chains, plot PPFs, special chainages, etc. in 20 minutes on average," David
The innovative tool has saved "massive" amounts of hours of work and
frustration. One recent project involved 109 roads and 426 curb returns. David
estimates it would have taken about 122 hours to set up, but with the macro it
only took about two hours - approximately a 98% reduction in setup time.
"Designers are no longer getting bored. You can imagine after doing 50 or 60
kerb returns manually they start to lose interest. Thanks to the macro, the
designers can remain more focused, concentrating on the design itself rather
than the setup. One designer had spent days doing 200 kerb returns manually on a
project, before we released the tool.” David says.
The time saved means that J. Wyndham Prince can also work on more client
projects, deliver them earlier, and then work on another area of a project
rather than having to wait for the first one to finish. "As an example, using
these tools we were able to prepare a set of plans for an 1800 lot residential
subdivision Development Application within 12 weeks including stormwater
design," David says.
The macro works so seamlessly that most people at J. Wyndham Prince now "take it
"They just assume that it's part of the package and probably don't understand
the hours that have gone into building it. They just essentially press a few
buttons and get the design done. And then they can concentrate on the rest of
the project," David says.
Huge time savings
The 12d Model macro has cut the design set up time by 98%.
Improved staff focus & productivity
Thanks to the macro, designers are able to stay focused on design, not on
tedious and repetitive work.
Increased client satisfaction
J. Wyndham Prince can now work on more client projects, and deliver early, due
to the time saved.
