Measured Drawings at different architectural scales

End of year review

Section Through Alamo Point Cloud

I’m just sharing a few snap shots from favorite projects as the end of the year draws near… here are a few from the Alamo:

Here is an thumbnail of an orthophoto elevation of the Convento.

“Maymont West”

…Aka Swananoa

Below is a photo I shot a few years back of the second residence of the Dooley family (of Maymont in Richmond). This building sits atop Afton Mountain on the Blue Ridge. How I wish it were still a part of Maymont – and shown the same amount of care and stewardship. It is such a shame that it sits there neglected… How I would love to make a careful set of drawings of this beauty…

The Maymont Mansion – Richmond, VA

Over the month of October we’ve been collecting scans throughout the Maymont Mansion in Richmond in order to create a whole house scan and a detailed set of measured drawings in support of a comprehensive HSR being prepared by Preservation Design Partnership in Philadelphia. Here are a few screen shots of the progress:

Blast Furnace Point Cloud

Blast Furnace Point Cloud

This is certainly the most complicated structure (series of structures) I have ever been charged with measuring and drawing. And it is BIG! I had to approach it globally as one giant cloud to create a set of master control points from which I could extract smaller set of local control points for higher resolution point clouds reflecting sub sets of the whole. Then I could create these and add them back to the whole.

Just quickly sharing a recent project snap shot showing the versatility of the field work techniques we’ve developed over the years. These are two screen grabs from a set of drawings being prepared as underlay information for a new design in an attic space that is difficult (and uncomfortable) to measure and draw. These line drawings were prepared from a series of photographs that had been modeled into a 3-D point cloud from which RGB forthophotographs were extracted to help enrich the line work.

Sample Orthophoto of Region 7 ( greatly reduced)

Sample Orthophoto of Region 7.1 ( greatly reduced)

In summer 2015 I collaborated with the team of architects and engineers studying Main Hall at VSDB. Another company was used for laser scanning in order to prepare floor plans of the building and adequate line drawings for the elevations. I was asked to prepare orthophotos describing the masonry surfaces of the building’s exterior to establish  detailed overview of the the various “as found” conditions this historic structure.

Some of the areas were challenging to access visually. The sample above is taken from a rather narrow courtyard or light well. It is a composite formed from dozens of close up shots collected from available photo stations.
