OVERTIME OVERVIEW

Project Soane started in mid 2015. It would be interesting to do a graphic of the burst of activity and pauses. My guess is that there have been 4 or 5 extended sessions (maybe 6 months each) , separated by gaps of 2 or 3 months when I switched to something else.



At the end of the Triumphal Arch post, I updated the model to BIM360  This process exports mesh geometry with attached data, plus 2D sheets and views , making the project available to non-Revit users through a web browser.

It’s called "publishing" the model, borrowing language from the UK standards with their four stage sequence (WIP to Shared to Published to Archived.)  WIP and Shared are essentially the same thing if your model is in the cloud.  But if consultants are modelling in their own silos you will need to "Share" on a regular basis.  "Publishing" is a bit more formal.  Usually it means a formal issue of deliverables to the client.  Archiving is automated in BIM 360 in the form of versioning. You can retrieve any previously published version from a drop-down list.



Haven't done much work on the sheets for ages and ages, but of course the model itself has moved on, so it was interesting to see what they are looking like now.

Will I ever achieve the mythical goal of a set of crisp record drawings and visuals for Soane's bank, as if he had designed it on Revit just a few weeks ago?  We live in hope.  However that may be, I am certainly learning an unbelievable amount about a great variety of topics along the way.  About BIM, about drawing, about history, about John Soane, about the Bank of England ... not least the history of its evolution.




The model is quite heavy now, and typically I work with most of the links unloaded. But sometimes it's nice to load everything up and save out some images.

I took screen shots of the model from various angles, firstly in Revit, then from the A360 viewer itself.  Revit gives you more visual options: cast shadows and ambient occlusion for example.  But the web viewer is accessible to more people on more devices.

The size and complexity of the model presents quite a challenge to the A360 viewer but it holds up remarkably well. Like most viewers it seems to convert Revit solids to a surface mesh. I'm intrigued by the “finger joints” that are sometimes visible, splicing surfaces together like carpentry.




I have been reading a book called the master and his emissary which suggests that the two halves of our brain deal with different kinds of attention. One is focused on the task at hand while the other stands back and reflects. The idea is that this split dates back to animals and birds which needed to perform precise behaviours while keeping an eye out for predators.

I think this duality is always present when I work on the Bank, dealing with modelling challenges while reflecting on the historical context, or Soane’s design rationale. But a more formal distancing is also helpful: publishing the model, writing up a blog post. My fallow periods perform a similar reflective function but spread out in time.



Coexisting dual perspectives are characteristic of Soane's work.  He was a classicist with an strong attraction to "the picturesque".  How do you balance order and chaos?  Quite a topical question I think.

I have a strong memory from the initial modelling phase of puzzling over the screen wall. Long hours were spent comparing the various conflicting sources of information, trying to understand the development sequence and striving for a consistent level of simplification and abstraction in the modelling. Why did he design it like that? What were the early decisions that tied his hands later on? How did he gradually crank up the architectural grandeur without creating any obvious break in style?



I've said before that Soane's Bank is like a medieval walled city with it's irregular maze of circulation routes. Evolution over time has been one of the major themes. It strikes me now that the gates facing North South East and West are another city like feature.

It's been a lonely effort at times, puzzling over the history of this fascinating building, but I'm very conscious of the many contributors and collaborators who have participated along the way.




The initial modelling and rendering stages focused on the transfer halls of the SE quadrant, plus the screen wall in its final state. Heartfelt thanks to the many sponsors, judges and competitors who kick started this whole process.  From the beginning I was obsessed with understanding how the Bank evolved over time: how Soane's work related to that of his predecessors.  Meanwhile, Russell & Alberto in particular did a fantastic job of setting a standard to aim for, in two specific areas that had been identified by the founders of the competition.




For almost three years now, we have been fleshing out the labyrinth of spaces that comprise the rest of Soane's Bank. Here the levels are much more complex and the information more patchy. Given how hard it has been to figure out this 3d jigsaw puzzle, imagine the titanic effort involved in design development.

The first floor rooms were quite extensive, but the highest cut plane intersects just three isolated areas.



Firstly there is the upper room at the West End of Garden Court.  Then there is the top floor of Sampson's rear courtyard (curved North wall be Soane) and finally the attic floor of Residence Court (servants' quarters?)  I'm pretty chuffed with the section through the Accountant's Office, extending through to the Residence Court.  Feels like we are really getting there.

If I can get the site upgraded to 2019 we will be able to access recently added new BIM360 features. These are not really designed for the kind of work we are doing on Project Soane, but I am curious to see how they can enhance our efforts.

FAMILY DRAWING TIME


Despite my best intentions, writing up my Project Soane exertions is still lagging behind the work itself, and this past week I've done a few digital sketches in the evenings on my phone, while lying in bed.  I don't wish to claim there is anything special about these.  It's just me, trying to re-ignite the intuitive, "sketching" side of my makeup, and reflecting on the outcome.

The first two were done fairly quickly in a flat, graphic mode with no post-processing.  The subjects are my son & youngest grandson, and my daughter (looking cool in silver wig and shades).  We live on separate continents  (typical "WhatsApp" families) &  I've been sharing these sketches as part of our regular chit-chat.




The drawing style is fairly crude, but choice of colour  balance and deciding how far to simplify, make these personal images.  There is an element of creativity, and at times (Joe's necklace for example) I am rediscovering the vitality that my linework had in my younger days.

The second pair benefit from "time spent practising" (John again, and his older brother Jack dressing up in WW1 uniform at the local museum).  I am relaxing a bit and becoming more ambitious.  Perhaps because of this, I felt motivated to add some digital trickery that results in altogether more impressive images.  Is this a good thing?  Does slicker imagery beat honest error?  I don't have any simple answers to these kinds of questions.



 
The processing is not just "pushing a button" There are subtle choices going on, mostly at a subconscious, "intuitive" level, to arrive at a colour balance and unity of texture that feels "right".  Once again, these are "my images" despite the assistance of two or three different "apps"  So I'm not really concerned about the "honesty" argument.  As long as I'm letting my emotions blend with my conscious thought processes while practising hand-eye coordination ... it has to be beneficial.

Now I just have to integrate this into Project Soane :)

TRIUMPH IN SIGHT?

As you enter Lothbury Court (hauling a load of bullion in a cart behind you no doubt) impressive flights of steps rise on both sides, but straight ahead ... a triumphal arch in the Roman manner.  It's almost a month since I set to work on this.



It was already roughed out, but needed to be lifted to the next level of development.  There are four statues atop of four Corinthian columns.  I don't know if there's a proper term for the way the entablature is projected over the columns in a series of spurs that act as bases for the statues.  And I don't know who the four mythical creatures are.  I'm sure they have signigicance.  For now I am simply using the grecian maiden who serves as a caryatid in a couple of the transfer halls.  That's the only mesh I have which is remotely suitable, so it will have to do.

 

The central panel at this level is a key pattern.  We only have a very grainy image to base this on, so I blew it up and traced over the image freehand on my phone. That gave me something that was crisp enough when loaded into Revit to trace over without getting totally lost. Started with a filled region, and copy-pasted the sketch footprint into an extrusion in Family Editor..



It amazes me how many variations you can invent, based on these "standard" classical devices.  Turns out that the standard is pretty flexible.  Maybe the BIM world can learn something from this ?  One day I will count up how many different key patterns Soane used in the Bank, double figures for sure.  I reused an existing face based family for a recessed panel, copied my extrusion of the basic module and adapted it at the ends and the middle to complete the design.



Next I needed another classical device, Caduceus: the staff of Hermes. It's a symbol of commerce (two snakes for commerce, one for medicine ... I think ?)  I had made a version for the dividend office (colonial?) sitting in the pendentives of the dome.  While pilfering this, I decided to "give back" my improved caryatid.  Last time I touched this area was a couple of years ago, before I learnt how to hide the edges in a CAD mesh.  So the caryatids were represented rather crudely by a stack of 3 or 4 blends.



So on we go, adding more panels.  Hanging garlands at the sides.  Leaves and ribbons, carved in stone, represented in digital 3d by simple extrusions!  But it works, just about.  I adapted the blind windows from the Lothbury Screen Wall, among the earliest families to be made for Project Soane and I can't remember who started them off.  I know I have updated them two or three times.
It suddenly strikes me that the pairing of Residence Court and lothbury court is a bit like a church.  The Nave is represented by Residence Court looking towards the apse which is towards the East as it should be)  The rows of free-standing columns stand in for the timber choir screens you often see in old cathedrals, and the bullion route provides the crossing.  I wonder if this metaphor ever occured to Soane.



Much more detail could be added.  Rows of dentils around the cornice for example.  For the moment I contented myself with pilasters to frame the apse, plus horizontal mouldings and a proper door in the middle.

Then I move on to the roofs either side of the bullion tunnel and the top floor rooms around the Bullion Court.  What fascinating irregular worlds Soane's roofs are, hiding behind the classical regularity of his elevations.  I love the way that the two half-domes jostle either side of the tunnel (the Chief Cashier's Office & the Power of Attorney Office (PoA)  But I'm not sure how to develop the interior of the PoA. It's a semicircular space with a circulation route along the flat side and needs to be top lit, so the lunette window seems right, but that long plain opening below is puzzling.



That was an excellent weekend.  I loaded up all the links and pubished a new version of the model to A360.  Russell's Consols Transfer Office, and Alberto's Stock Office sitting proudly with their grey roofs, top centre.  I haven't quite reached the level of detail that they achieved in the rest of the model yet, but it's coming closer.



I'm not quite happy with the roofs over the residence court yet.  Nothing much to go on there, I will have to make something up eventually.  Maybe they were just flat as I show them now, but other areas that used to be shown as flat expanses have developed so magnificently ... ideas are welcome.  But all in all, I'm feeling very positive.  Who knows, I may even "finish" this project one day.
