USC/CW/ICC Modernization 1994

The Arthur Mellon Auditorium (ICC Building) 1994

Here is a composite drawing of the first really huge (HUGE) building that i used photogrammetry to measure and draw back in 1994.  This work was completed with Ben Frombgen at IAT when we were based in New Haven, CT. We did a complete set of elevations, eleven building profiles (that were later turned into building sections by our client, RTKL) plus a window schedule. It hurts for me to remember how little we charged for this work!  But it was one of our first big commissions and it seemed like a lot at the time.

This is also the first project on which I used a laser measuring device.  If I recall correctly, we were asked to deliver this project in metric units.  I remember being thrilled that the Leica Disto that we bought back then (which was as big as a large box of spaghetti) could switch between units.

I remember also that we had access to a great set of San Francisco based architect Arthur Brown Jr.’s original design drawings (from the 30’s) that were just stunningly beautiful and provided such a contrast to the general level of quality in CAD drafting at the time. Not only was the quality of drafting so great (a beautiful hierarchy of line weights, crisp fluid clarity of description) but the organization of the drawing set was so intelligent and efficient.  We resolved to find a way to draw as well with a computer and have been trying to do so since!

Arthur Brown Jr. also designed the san Francisco City Hall and Coit Tower.

Measured Drawings on Paper

Basilique St Denis: side and end views of double butress & window

Here I have posted a couple of older drawings from the nineties.  Both are scanned images of prints. The first is a sample of the types of drawings that we were making at Innova for the Basilique St. Denis located north of Paris.  We were charged to create drawings that could delineate each individual construction unit so that a stone mason could make a detailed assessment of the conditions of each, record it, and turn the whole set of documents into a work order.  Some stones were to be completely replaced, others scaled back and replaced with a new facing, many were in fine condition etc. etc.

The second image shows a print of a drawing after such an assessment was made for the terra cotta, masonry and stone cladding that compose the Ocean City City Hall in NJ.  A coding system was devised for individual construction units and linked to a data base.   This print was given to me years ago when I was based in New Haven, CT by Michael Henry of Watson Henry Associates.  While it is possible to create such a document digitally in the field with a tablet computer and so forth, I think that this methodology (making detailed drawings to be printed to appropriate scale onto paper) is still valid today.  Many restoration projects are harsh environments and approaching them with a good set of drawings in hand can be indispensable for creating an accurate record of a hands on assessment.

These paper documents also have archival value in a way that digital files do not.  I once was doing a project like this in New York City. By day I was in the field marking up sheets with a four color pen and by night I was entering my info into my lap top in my hotel room.  (This was valuable because I was able to foresee questions and resolve them the following day before returning to Virginia).  Then on a Thursday morning my hard drive did not wake up and had to be sent out for “emergency disc recovery” – a harrowing experience.  But I had my work backed up to the previous Friday so all I really lost was the data entry from my field sheets to my drawings.  I was so happy to have paper in hand to bring back and use the following week while I waited for my lap top to come back from the dead…
