Roger White Stoller
Artist Andrew Hedges,
lead fabricator at the
Studio, reviews progress
on hanging the stainless
parts over the structural
wall support system.

Partners with
Stoller Studio on
numerous
projects, we
remain grateful
Nor Cal for their
skill, dedication,
and attention to
detail, required
for the high-craft
artwork Stoller
Studio creates.
Laser Cutting & Forming
The structural support and all the
artwork panels designed at the Studio
started fabrication at Nor Cal Metal Fab
in Oakland, CA. Without this type of
industrial machinery, Luminous Oak
could not be built.

The structural wall
plates shown at left
are being used first
to fabricate the
attachment system
of the sculpture.
When this has been
completed at the
Studio, they will be
disassembled and
shipped to the South
Bowie Library to be
permanently built
into the fireplace
wall.
“Attachments”
The image below
shows an inner post
welded to a
structural wall panel.
The concentric
square tube slid over
the post will be
welded to the back
side of the sculpture.
Structural Support
System
This wood wall was created in the
Studio as a scaffold upon which to
fabricate the sculpture.

“Connector” plate
detail at right
shows how the
connection is
expressed from
the outside - as
part of the artwork.
The welds will be
ground out later in
the finishing
process.
Below, the back of
two connectors are
shown with
temporary nuts
and clamps
holding the parts
for assembly.
Connectors
Attachments
Image to the right shows the interface
between the structural posts and the back
of the sculpture. After a perfect
alignment is achieved the sleeves will be
welded to the back of the sculpture,
locking the alignment in place. This
assures that after the support structure is
built into the Library wall, the sculpture
will slide right into place.

Studio Director
David Naisuler
checks the overall
structural-design
and rigging system
he designed for this
stage of the
fabrication.
Billowing Stainless
The tree canopy & trunk billow
far from the wall - these four
sections are joined to each other
by “connector” plates, shown in
detail previously on page 4..
The roots below are made up of
two panels. Nothing below the
trunk requires a “connector”,
only attachment posts.

Turning the Corners
The roots run out to the sides of the
sculpture to take a 90º turn around
the corners of the fireplace wall.
David and Andrew align the
side root panels that will be
welded and finished to become
a single piece.

Shown above is a
panel with lines
laser-etched into
the steel. These
will guide the
hand-brushed
texturing in the
next phase. This
process will
create the
finished surface
of the sculpture.
To the right is a
full scale one foot
square test
section showing
how the different
textures will look
on the final
artwork.

This computer
model image of the
artwork on the
fireplace wall in the
South Bowie Library
shows the second
preliminary lighting
test. We are
currently testing
three LED lamps,
one on the center of
the roots and two on
the canopy.
Next, Hydrell
Lighting will be
providing additional
computer testing
with virtual LED
specifications.
From these tests we
will order fixtures
and locate
placement on the
Library ceiling, to be
installed by the GC.

Detail-Design & Engineering
Prior to this update the team completed the detaildesign
and engineering phases of the project. Ma
Chi Chen, Ph.D. of CES Engineering completed
Stoller Studio’s calculations on the support structure
and attachment points. This was reviewed by Matt
McArdle of Columbia Engineering in Maryland
and has been incorporated into the final
engineering package to be wet-stamped by Mr.
McArdle for PGC.
