PLQ2.5 – Check, Review, Approve

Hello BIMfans,
After publishing my Architectural Model and my Mechanical and Electrical Models last week.  This week I am looking at some of the pedantic fantastic comments you have provided back and what I have done to resolve them; thank you for these.  Remember there is still another week to contribute so keep those comments coming!

So let’s see what comments I have had back.


Volume Code

I was told that I have used the wrong volume code.  I had issued using the volume code XX-‘No associated Volume’, however, my Employer’s Information Requirements clearly states that I need to follow BS1192, which uses the default code ZZ-‘All Volumes’.  I agree, and have now renamed all of my outputs to use ZZ, and updated the appropriate sections of my BIM Execution Plan to suit.  Technically I complied with my BEP, but as Keith told me, I am a stickler for the standards!

COBie Contacts

I was told that my COBie contact sheet should include all of the suppliers, installers, and other contacts related to my home; not just the project design team.  I agree, and have now revised my COBie contact sheet to include all of the applicable contacts.  It’s hard to find guidance on the scope of this worksheet #excuse, but Dan knows his stuff!  I also really don’t like using the PM table in uniclass 2015 for this, but there isn’t a roles table.

I also have a spare at the bottom for any unknown contacts and to be DPA compliant I’ve only used email and contact details that are publicly available.

COBie Documents

I was told that my COBie documents sheet should be populated with my other outputs such as my drawings.  I agree, and as Revit cannot hold this information have used my COBie Post-process sheet to record all of the applicable outputs.  Nick, as usual, is technically correct (the best kind of correct).

I was also told that my COBie documents sheet should include other documents such as my property condition survey and any designer risk assessments.  I agree, however, there are no designer risk assessments as I haven’t done any design on this project.  Similar to the above I have used my COBie Post-process sheet to record all of the applicable documents as well as my outputs.  Good thing I have no design, as I have no PI insurance!

From my Prologue, you can see I have a lot of documents to manage.

COBie Jobs

I was told that my COBie jobs sheet is empty, therefore I must not maintain my home.  I agree with this, but as I have pointed out in a previous post, jobs are optional; so I am not going to use it.  However, on reflection it is worth considering, so It’ll feature in the new year when I am looking at my operational Plain Language Questions.  As I told Chris, despite what my COBie sheet says, I do vacuum my house!

IFC Co-ordinates

I was told that my IFC file contains some co-ordinates for my house; luckily for me those Co-ordinates are in London.  This is because of my data security requirements within my Employer’s Information Requirements stated each model had to have the co-ordinates of 0,0,0; and without changing the location in Revit, it has defaulted to London.  As a proud Welshman I’m disappointed of this default location, but happy my data security measures have worked!

Splash Screen

Also, keeping with my BIM execution plan, I had also stated that all outputs should include my ISO7200 title block, but I had not included it in my native models.  To resolve this, I have added them as a splash screen when the models are opened.  Do I get points for spotting my own mistakes?

This has had the added benefit of reducing my file size by 500KB as my model no longer has to store such a detailed thumbnail image

Note: I have also had one or two comments about the data format of some of my COBie fields. However, I’m aware of some other comments about this due next week, so I will deal with them all during next week’s post while I publish my documents.

And there we have it.  Thanks to the support of our wonderfully open community, I have been provided with a number of fantastic comments have have been used to improve the outputs from my information model.  This means that following another week of excellent input I should be ready to complete PLQ2.5!

Model Generation:
2.1 What existing information is available?
2.2 Is there sufficient information to produce a BEP?
2.3 What is the layout of the house?
2.4 What assets are contained within?
2.5 What asset information can be linked to the graphical model?

Now that I have the first set of comments resolved, lets see what you guys come up with next week…
