The Second Century --
We honor our past and
strive to create hope for the future,
with every student that peers through
the great telescope's eyepiece.
During the past 5 years, the University of Denver/Astronomy program has been
fortunate to receive the help of many interested persons in renovating and
restoring DU's historic Chamberlin Observatory so that it can continue to
serve the community well into the new century.

From: Dr. Robert Stencel, Prof. Astronomy, Chamberlin Obs.
Subject: Specs for additional requested Chamberlin work, spring 2006, SHF
Here are our requests for useful modifications to be made to electrical,
mechanical and plumbing facets of DU's historical Cahmberlin Observatory,
to enhance functionality as academic, outreach and research space in
support of the Dept of Physics & Astronomy, NSM and the public. Mr. Reid
and I are at the ready to clarify our requests and review drawings prior
Assumptions: ALL exposed conduit will be redone flush into surfaces where
possible; retain most existing receptacle locations except where noted.
"Receptacle" means 2-plex 110vac plug-in unless otherwise spec'd.
EXTERIOR ELECTRICAL & PHONE
Buried electrical, phone and future digital cable channel from street to
basement. Ditto for run to Student observatory
BASEMENT: [#1] big letter signage for water, electrical, gas interior
1, main pier - [a] add signal from main sump to new fire detection system
2, boiler - no changes but heating system needs complete review for noise
3, storage - no changes
4, coal bin: [a] entry wall receptacle and light switch [moved from boiler
5. sink room: [a] add overhead light in east end
6. transit pier - [a] add receptacle inside door frame; [b] add signal
from flood detector to new fire detection system; [c] move one overhead
light from south to north half of room
1. North entry: expand receptacle from inside "phone" room to foyer or
from light switch
2. Phone room: no changes
3. Dir. office: [a] upgrade floor receptacle; [b] add 2 receptacles 8
inches above cabinet top on east wall; [c] replacement, period lighting
for ceiling?; [d] evaluate and upgrade receptacles on north, west, south
walls; [e] spotlight for Chamberlin portrait on NW fireplacewall?
4. Classroom: retain at least 6 receptacles in outer perimeter in the
larger expanses between windows; [b] add up to 6 on inner square perimeter
5. South entry, exterior: [a] upgrade receptacle on east wall at landing &
replicate on west side
6. Transit room: [a] consider period lighting scheme analogous to
7. Restroom: [a] add receptacle next to light switch; [b] add hot/cold
spigots under sink for filling buckets
SECOND FLOOR & DOME ROOM:
1. Landing: [a] retain receptacle, perhaps on interior wall rather than
under north window
2. Dome room: [a] receptacles 18 inch above floor between each pair of
windows (4 total), retain existing receptacles on north wall; [b] add two
receptacles under the computer table at the pier; [c] upgrade wiring to
dome rotation motor (north wall) and add capacity for low power in-dome
lighting & control circuits.
3. Observer room and west "chamber": [a] add receptacles next to existing
light switches on west side of obs room and interior east side of
chamber; [b] investigate open electrical box near obs room entry door,
southeast face and refurb as needed.
1. North service porch: the UV-capable membrane roof and gutter-liner
system installed circa 1995 with 20 year warranty appears to be doing a
great job and should not be disturbed; protective mats might use
2. Chimney capstone cave-in needs attention.
More to follow.
