Porch Sketch (Plan, Section, Elevation, Detail)
My employer and I had a conversation a few months ago about understanding and comprehension, and I’ve been thinking a good deal about it over the past week. One of the architects in our office was working on sections of an auditorium for a high school that our office is renovating and coming up with an addition, and as I asked him how the sections were coming along he replied,
“I have to draw it myself, because I have to understand it. If the contractor asks me questions, I have to be able to think my way through it.”
I left the office smiling, digesting what he said. He desires a deep level of comprehension that comes through a three dimensional understanding of how the object would be manufactured, transported, and assembled in the auditorium. He needed to know how the connections would be into the existing conditions, and if the existing walls could carry the load for the new trusses and lighting.
More than a month ago, I was working on record drawings to give to a client of work that we had built, and I sketched this (porch column, above). It is a steel column, expertly hidden inside of a masonry base with concrete sill and a metal sheathe. Looking at the construction documents, I was able to grasp how it would be built, and how the metal would be bent and connected with a backer rod and sealant to keep it together. To prevent the masonry from getting too much moisture, the concrete sill was cut around the perimeter to create a drip edge.
I “understand” it when I glance at the built construction and see a column, supporting the load.
I “comprehend” it when I can explain it to you and answer your questions about how it will be built, how I might estimate its cost, and how much load it may carry (based on calculations of the size of the steel).
Last but not least, I wanted to say I have been inspired to draw more and to post my sketching from the work of Suzanne Cabera and Edgar Cabera, both of whom keep updated, beautiful blogs about sketching in their life. If you two find this, I want you to know that seeing your sketches reminds me of why I fell in love with the joy of sketching.
Tomorrow night is busy, I’m going to a dance with my fiancee, but this weekend I will post a section of the Paul Sawyier Public Library.
