This Blog is dedicated to all things to do with Building Information Modeling.
I'll be blogging about challenges that I come across as BIM Manager as well as points of interest that are related to BIM. Blogs on tips and technical "How-too's" to help you out with creating your BIM models correctly.

Zombie Projects… project that are resurrected from the
dead… how to deal with them, how to bring them back to life so they wont bite
you on the neck.
from the dead!
I refer to projects that have been “raised from
the dead” as Zombie projects.
Projects that have been started in Revit years ago,
and for one reason or another, were then put on hold only to be resurrected
again after a number of years…or a number of Revit versions.
Bringing a project back
from the dead can be both challenging and fraught with danger.
Zombie projects can react
in unexpected ways as the program tries to manage data and parameters that may
not exist, or the function has changed. Creating a “Frankenstein” project where you’re cutting and chopping sections
from the old project to create a new project can infect a new project with
indiscriminate data or elements that can confuse and anger the victim causing
mayhem throughout the team.
Be diligent in cleaning a
project when moving it to the next stage in life, use sterile components to
reduce the possibility of infection that may occur both immediately and at a
If you have to raise a Revit project out of the
grave and breathe life back into it, here are some tips so you wont get bitten
on the…umm….neck…by the project.
Create a back up copy or Archived copy before
commencing the upgrade process, you need to provide a record or where you left
off and where you’re starting from.
Unload any linked models before upgrading, or it
has to upgrade them at the same time as upgrading the intended model. – upgrade
the linked models independently.
Delete any “old” local files on user’s computers.
Purge all unused (do it 3 times to truly get rid
of everything not used) (again, not entirely necessary, especially if you’re
going to continue working in the model).
Review and Resolve warnings.
Upgrade in steps, don’t go straight from 2012 to
2016, do it in stages such as; 2012 to 2014 to 2016.
Remove all unnecessary views (anything not on a
sheet) before upgrading. This is also good practice for file maintenance.
Transfer project standards from the Seed File.
This will port across the latest standards.
Make sure everyone on the new version is on the
same Revit build.
Gather Data before and after upgrading, compare data
to check for consistency and completeness (Doors, Views, Sheets, Etc). Use
tools like BIMlink and Schedules to
output any critical data like door schedules, RDS, etc.
Data loss in an upgrade can
be sneaky and hidden until found. If you compare the data right away you can
often see critical errors that have occurred during the upgrade.
When to Rebuild
If your project is older
than Revit 2012, let the dead lie…You
will seriously need to evaluate the pros and cons of upgrading verses entirely
rebuilding the project. The benefits of rebuilding the project are too numerous
to mention, but here are a few benefits. You’ll be starting the project with
the latest seed file, utilizing the latest application and components that have
been proven to work. For me, if the risk is too great, I’d be inclined to
rebuild the project. The time it takes to rebuild the model is an investment in
project stability. Building a monster…err..
project, using the latest components and tools reduces risks, and promotes a

I get that
question a lot. When I first started promoting Revit as a replacement for
AutoCAD, I talked about how Revit would reduce the time it took to complete a
not what happens.
I don’t see
a dramatic decrease in project delivery time, but I do see an increasing ability
to deliver projects.
experience – and that of many others – has been that Revit does enable faster
creation of drawings. I can certainly produce a set of drawings for a generic
building a lot faster in Revit than AutoCAD; however, increased project demands
such as design complexity and timeline/budget constraints make it hard to see a
measurable improvement in project delivery speed. Managing the rising levels of
information and data required on projects inhibits our ability to quicken our
pace. That being said, we have seen a measurable improvement in the quality of
our deliverables and our service.
these more qualitative analytics can be difficult due to the diversity of our
projects. Each project is unique, with a distinctive set of constraints and
honestly say that some of our projects would not have been successful if Revit
had not been used. As opposed to following traditional CAD methods, using
Building Information Modeling (BIM) allows us to deliver a more concise,
thought-out design that is better coordinated and executed, and with fewer
benefits of using BIM go beyond delivering a set of drawings.
Quite simply, BIM
helps us do better work for our clients.
