I am too fast 
pyparsing.py can be found in the zip on top-level but not within the folder “blender” within the zip.
That is correct, it should be in the top level, not inside the blenderbim folder. When you install it to Blender, it should copy the pyparsing.py file to your Blender add-ons folder, but it sounds like it didn’t. Can you please check if it is there? You can see where your Blender add-ons folder is here.
To be safe, when upgrading BlenderBIM versions, I recommend completely removing and uninstalling the old BlenderBIM first. To uninstall, you must manually delete all the files that it created. You can see a list of the files to delete in that documentation website I linked to. Note that when you install, you do not need to unzip the downloaded file 
Hope it helps.
pyparsing.py is not in the add-ons folder or any subfolder.
I have to break now and will continue in some hours.

As it is not there, I recommend starting fresh and installing BlenderBIM again. It should work out of the box. If not, a workaround will be to just copy the files over manually. If you have to resort to the work-around, contact me via private message or email (dion@thinkmoult.com) and we can debug it without disturbing the forum
Cleaning the webbrowser cache before downloading the zip did solve the problem.

New update!
- Documentation added for the context panel
- Site objects are now imported
- Bugfix to export different types of curve objects
- All non-polygonal extrusions now have an Axis representation exported
- Material properties are now exported (like density, youngs modulus, etc)
- New sample attributes for doors and windows shipped with the add-on
- Point clouds now can be exported to IFC
- IFC structural objects are now exported
- UI improvement to only show predefined types and userdefined types if it is possible
- Structural objects now export a topological reference representation
- Parametric material profiles are now supported (rectangular, circular, I-Beam, etc)
- New UI to manage material attributes
- New UI to change material assignment (single / layer / constituent / profile set)
- New UI to create a property set override instead of having to write properties in separate CSV files
- BIMTester now includes model setup vocabulary, drafted in collaboration with BuildingSMART Australasia co-founder @john.mitchell - it tests basic project attributes and geolocation for both IFC2X3 and IFC4.
- BIMTester now allows custom JUnit directories for better cloud integration
- Bugfix where some context representations were not exported now fixed
- UI to specify structural boundary conditions
- New UI to specify structural member connections
- Can export a group of structural objects into a Structural Analysis Model
- Importing now has a progress bar and more consistent logging
- Documentation for BlenderBIM and IfcOpenShell merged and restructured
- New workaround for Revit incorrect geolocation being placed on the building object - enabled by default
- Assigning product types is now done by a property instead of the Blender parent relationship to allow it to scale on large files
- New experimental script to convert IFC into Code_Aster input for 100% free and open source structural analysis
A few pictures highlighting the major improvements…
Point clouds! Woo! As you can see, BIM, point clouds, and 3D annotations are all fused together - this presents exciting opportunities for recording this as-built fusion for our built environment!
As BlenderBIM can now author an IFC file containing structural analysis models, there is now an ability to convert this IFC file into a format that Code_Aster can read to perform structural analysis:
The results are visualised with Salome_Meca and ParaviS (effectively Paraview included into Salome_Meca). Shown is the deflection of a single cantilevering beam.
This is the start of a pipeline where structural modeling and structural analysis can be done with a 100% free and open source pipeline through IFC!
Shown below are the test vocabulary developed with @john.mitchell to check geolocation. This is still relatively fresh, but we hope to standardise this to verify that all models produced are properly geolocated.
Also quite exciting is how FreeCAD was combined with BlenderBIM - FreeCAD was used to parametrically model with constraints (Catia-style) a stair tread which was sent in STEP format for manufacturing. The native parametric file was associated with an IFC document association, and the FreeCAD export supplied the solid parametric representation item, whereas Blender provided the mesh based representation item. This demonstrates that it is possible to mix different mesh modeling techniques across different programs and use each to their strengths. Many thanks to @yorik who has made a lot of this possible in FreeCAD.
The same tread is shown with a faceted brep representation in Blender below:

It is impressive to see how blenderBIM and FreeCAD can complement each other.
Cleaning blender addons folder after removal of old version in blender and installing new version afterwards solved the installation problem. 
Thanks @Moult !

Most relevant to the AEC industry is …
USD support, to allow for the transfer of complex geometric scenes where IFC may have limitations due to its monolithic nature.
Improved AI denoiser, for better architectural visualization for faster, smoother, concept designs.
Custom bevel profiles make it oh-so-much easier to do various types of architectural modeling.
But so much more … better sun position integration, parametric vertex welding … the list goes on.

A new version of the BlenderBIM Add-on v0.0.200228 was released today! It’s been a month since the last release, but there are lots of new features!
- 12D files, which usually have absolute coordinates, are now imported into Blender with an offset to allow you to work in local coordinates for vertical BIM
- The BIM audit panel now allows you to select a particular BIMTester feature, and write tests directly from the UI instead of needing a text editor
- Your spatial tree can now have geometric representations (most importantly, this allows you to export an IfcSite terrain)
- Quick project setup button now sets up spatial objects too
- Sites can now export a reference long/lat attribute
- When importing, it now remembers what IFC file the data came from (in preparation for partial writes)
- Minor bugfixes related to missing items in dropdown menus, curve orientations upon export
- Import now associates type products
- Bugfix allowing you to import multiple spatial structure elements with identical names
- New option to toggle import of opening elements
- Improved IFC-to-Code_Aster script
- Preset render settings for creating documentation and diagrams
- Create dimension annotations in 3D from any orientation instead of for a particular view
- New support for IFC projection elements (opposite of void elements)
- Allow you to create other types of leaders and section levels from any orientation instead of for a particular view
- IfcPolygonalFaceSets are now imported with the correct units (useful for sites and terrains)
- Extra checks to ensure exports don’t create GlobalId collisions
- Allow duplicate names for both mesh and curve data
- New option allowing people to maintain parametric behaviour to generate multiple IFC objects, or to bake the results into a single IFC object
- New IFCPatch tool, allowing you to patch the data in an IFC file based on a series of preloaded “recipes”. These allow you to workaround various limitations in other IFC authoring exports in a safe way without breaking the rest of the IFC data. Recipies include:
- Reset spatial element object placement locations
- Offset from absolute coordinates to a local system
- Remove representations from sites
- Offset IfcBuildingStorey elevations
- Set reference elevation
- BIMTester now shows test results with a percentage success rate
- IFC import now imports pset data
- 2D grids are now imported even though curve data isn’t enabled, given the importance of grids. Support added for IfcGrid and IfcGridAxis
- New ability to search for IFC objects by their attribute or pset property values with a case insensitive string, with support for regex for super advanced searching
- You can select any IFC attribute or pset property and colour code the model by the value for a visual cue when auditing IFC data
- Minor UI clean-up to hide panels by default
- New import option to toggle import of IfcSpace objects
- Handle import coordinate offsetting of IFC2X3 files created from Tekla which are poorly geolocated
- Version bump to the latest IfcOpenShell library, which includes fixes for more stable geometry import
The stair design, which was done purely using open-source software, is moving into fabrication. A couple of cute pictures:
… and from the front …
Thought I’d also share a cool use of Blender that inge_handagard on the BlenderArtists forums had showed me. He used BlenderBIM to automatically parse point data from a compactor machine when building a highway, and creates an IFC from them so that BIM users can see the results to ensure that the road is being properly compacted.
Shown below is the IFC opened in Navisworks (proprietary), which is how others might open the file. This process is run automatically every day! (Blender is highly scriptable and automatable)

Hello @Moult !
From the Universities of Argentina we are interested in contributing work to have an open source BIM alternative within a reasonable time. We think the work you are doing on blender is brilliant !!
I am doing a comparison between Revit / Archicad / Bricscad to fix targets, and it caught my attention that you managed to extract 2D construction documentation with BlenderBIM. The ability to do construction documentation is very important !
I have installed Blender + BlenderBIM but I don’t see this functionality. Will it be part of a new version not yet released? Can we test it? .
Greetings from Argentina !
Joselaks
Thanks @joselaks! The functionality is included, but not documented - so it is not obvious. Perhaps it’s easier to share a screen to demo this? I am generally online during all working hours Sydney time (and them some) in the IRC live chat: https://blenderbim.org/community.html
The ability to do construction documentation is extremely important, but still very raw. I am happy to say that for very, very small projects, I am able to apply it already, so perhaps with increased streamlined workflows and optimisation of the cutting process, it will grow to larger projects.
Here’s another sneak peek of some documentation produced with BlenderBIM (yes, these are colourful, but I can also produce pure black and white style drawings if it is appropriate for the job):

I thought I might try and record some mini demo videos on how parts of the BlenderBIM Add-on works, because it is quite feature-packed and can be quite daunting. Also, recording videos is faster than writing documentation
Feel free to check it out - here’s the first to do with section planes, which is today’s new feature.
This one isn’t specific to OpenBIM / IFC / BCF, so in the future, I will refrain from posting generic BIM videos here, but instead may only post them when it is relevant to IFC and BCF… for example, Blender now supports writing your own property set template definitions, which is quite unique and probably warrants a demo!
