My office in the Science Building overlooks the building site of the Downing
Planetarium. The first real dirt was moved on November 6 to clear the building
pad site, and to dig the trenches that would bring some of the utilities
to the building. The trench runs from the Planetarium, across San Ramon
Avenue, and down between the Science Building and the Satellite Student
Union. The staircase at the West end of the Science Building gave some nice
views of the trenching and drilling. Images of these activities will be
found below. |

Phase
I construction involves clearing the site, bringing in utilities and pouring
the pad. This process was begun on November 2 by moving the Marching Band
Tower further East. Please click the thumbnail to see the full-sized image.

 After
fencing off the main planetarium site north of San Ramon Avenue, workers
also fence off the area between the Science Building and the Satellite
Student Union to prepare for trenching and installation of utility lines
from the campus to the site.

When
large telescopes are used for the first time, the event is called "First
Light." On November 6, after many delays, ground was finally broken by
large dirt-moving vehicles. We called this event "First Dirt." When you
consider that our official groundbreaking ceremony was way back on March
21, this was quite exciting. For more First Dirt pictures, click on

Now the earth is being moved in earnest. The sod has been removed from
the place where the foundations of the planetarium will go. On the left,
the northern edge of one of the utilities trenches is being dug. Click
on the picture to see the full-sized image.
South of San Ramon Avenue, the soil from the utilities trench is loaded
into a truck.
An unforeseen small water main is encountered by the backhoe. I later
heard that the backhoe carefully excavated around the line without breaking
it. Then one of the workmen discovered the hard way that its walls were
much thinner than they thought. When he stepped on it, the main broke,
treating him to an impromptu soaking.

panoramic shot from the third floor of the Science Building. This
window is now the site of the live Web Camera that can be accessed from
the Planetarium Web Site.

To run the utilities under San Ramon Avenue a special underground borer
is brought in and positioned with the large crane you will see in several
of the pictures below. Click on the picture to see a full-sized image.

November 18 was a beautiful Fall day. Click on the picture to see the
full-sized panorama shot standing just South of San Ramon Avenue by panning
from West to North across the building site. The crane used to maneuver
the boring apparatus is prominently featured.

On November 18 the crew was busily creating the little jog in the utilities
trench that runs from the Science Building toward a junction near the
Satellite Student Union. (See the map at the top of this web page.) This
picture is a mosaic of twelve digital camera shots and is 494K in size,
so be patient if you have a slow modem and click on the picture to see

Last week we learned that the soil under the planetarium site had become
saturated with water, making it impossible to place a foundation on it.
The solution is to remove all of the wet dirt and replace it with dirt
that can be compacted properly. In this picture you can see the standing
water in the foreground. In the background the dirt is already being removed
with a large tracked excavator.
Here we can see the entire site, with the dirt removal in progress. This
will be moved to a location on the Fresno State Farm to be used as excellent
soil.

After the excavator had completed its work, a layer of Geotek was rolled
out and laid down. Next truckloads of aggregate were smoothed out over
the base of the site. The final layer will be fill dirt from a ponding
basin that won't have the squishy water problems that the old dirt had.
We are now ready to compact the soil and lay the actual foundations of
the Planetarium. Please click on the thumbnail pictures to see the full-sized
images.

December 8, 1998
The layers of good topsoil from a ponding basin are put down and compacted
by driving trucks and rollers over the layers as each is added to the
site.
By the end of the day several layers were in place. The final layers were
put on the following day, December 9. Click on the thumbnails to see the
full picture.

The site has been filled to six inches above grade and is awaiting final
compaction tests. Next week we expect to see work continue on electrical
and gas line utilities around the edge of the site. After that, work on
the forms for the footings of the building pad itself is scheduled.

Today a deep pit was dug on the South end of the site for installation
of the electrical vault that will serve the planetarium. This image was
taken from the Third Floor WebCam set up in the Science building by Roger
Key and John Beckman of the Physics Department. (The webcam was removed
after the Planetarium was completed.)
For an additional picture of this operation, click on [Vault01]
and for an animated picture of the digging click on [Vault
Animation]. If you look carefully at the animation you can see how
deep the backhoe must go to reach the bottom of the pit.

To refresh your memory on where everything is, the electrical vault hole
was dug yesterday and now has yellow tape around it. This morning another
trench was dug between Science and the
Satellite Student Union. This afternoon more
trenching is being dug on the Western edge of the site, as shown in
the picture above.
Reporting on these cuts in the ground may not be all that exciting, but
without power and sewage we would have very unhappy audiences at our planetarium
shows. Stay tuned for water, gas, telephone and computer lines! Even starships
need life support and data systems as well as photon torpedoes.

Today after watching the backhoe dig yet another trench at the southwest
corner of the site, I noticed a truck with big concrete boxes and a crane
pull into the site. It was time to put in the Electrical Vault.
For an animated picture of this operation, click on [VaultAnim-736K].
(After this picture loads, you may want to click the Reload button on
your browser to repeat the animation.) See Dec 15 above for a key to the
vault location. They first lowered in a concrete slab floor, then two
wall sections as shown in the picture to the right, then a cover, and
finally a manhole access.
As I type this they are continuing to trench both East and West of the
Electrical Vault.

Today a bit more trenching is still going on at the Southern border of
the site, but most of the action seems to be connecting and laying the
pipe that hooks to the electrical vault. Please click the image above
for a larger view.

I believe we may have another first. The first concrete I've seen was
poured on the site today. You can see the truck at the lower right of
the webcam site picture pouring concrete into one of the trenches coming
from the Electrical Vault. There is also work going on in the center of
the site as they prepare to place the foundations of the building itself.

Yes, Virginia, that white stuff on the ground is SNOW. According to this
morning's Fresno Bee (
Believe it: It's snow), this is the first official snowfall we have
had here since 1975 when a "trace" was reported. The snow even arrived
at an astronomically significant time. Today is the first day of Winter.
Undaunted, your fearless and dedicated construction crew is already hard
at work this morning. Please click on the thumbnail to see a larger image.

Happy 1999. School is back in session but not a lot has been happening
at the Planetarium site since late December. Most of Phase 1 has been
completed, which brings utilities to the site. With the snow and the rain
I'm sure the construction workers were just as glad that Phase 2 was not
quite ready to go yet.
My daughter Kirsten came home from grad school over the holidays. I took
her out to see how the Planetarium was coming along that we had talked
about back when she was in high school. Things may be happening more slowly
than we would like, but it is gratifying to see the project actually taking
shape.
The planetarium committee has been hard at work. In this shot taken on
February 8, 1999, Gary Wilson from Facilities Planning was briefing us
on the new cost projections for Phase 2. Once this all gets sorted out
we can finally begin work on the building itself. A lot of people are
involved in making this happen, so we just have to be patient until all
the ducks are put in a row.

That's all for now. As new things happen, I'll add them to
this site. If you have any questions or comments, please send me an e-mail
at david_zellmer@csufresno.edu.
