[Escoordminutes] ES Div Coord. Minutes - June

[Lew Serna]

Minutes for the ES Division Coordination Meeting on Tuesday, June 22, 
2004, at 10 am, in the LL CB conference room.  Attending were Ramon 
Gutierrez, Lew Serna, James Sullivan, Tom Frost, Pat Lewis, Guy 
Stanzione, Mark McKinnon, Brent Avery, Gene Cole, Patty Lindsey, and Jon 
Thunborg,

BUDGET   Serna.
Budget allocations for ES Division include $114.8 K for Facility and 
Antenna infrastructure projects in addition to a $486.5K operating 
budget.  Several operating budgets are already exhausted such as the 
Electrical and WYE groups.  Supervisors may reallocate monies within 
their accounts if necessary to cover cost overrun in these groups.

The Facility and Antenna infrastructure projects to be accomplished this 
year include the following: Repair PT rail, Foundation for EVLA 
warehouse, Replace 2 VLA azimuth Bearings,  Repair MK Rail, Replace VLBA 
BR subreflector, Repair water tank, Concrete intersection at masterpad, 
Install concrete timbers, Safety Railing in Antenna Assembly Building 
and Intersection Timber Building Jigs.

AZ Bearings.
Antenna 14, the second prototype EVLA antenna bearing change is 
completed.   The outer bearing race was damaged.  All parts from the 
bearings removed from antennas should be stored until they are scheduled 
to be shipped to Rotek for repair. These parts are need for measuring 
and fitting new parts.  Antenna #16 will be scheduled for bearing 
replacement at the end of summer ‘04 (September sometime).  Antennas 16, 
18, 20 and 26 have bad bearings that will eventually need to be 
replaced.  A spare bearing should be maintained at all times. An 
estimated three weeks in the AAB are required before a bearing change 
can occur.  Staff members from the Jodrell Bank Observatory, in the UK 
are very interested in witnessing our bearing change and may visit for 
Antenna 16’s bearing change in September.  Try to prepare as far in 
advance as possible.  Guy Stanzione will be the Bearing Change 
Supervisor for Antenna #16.

NEW PROJECTS:
Control Building transformer The replacement of the Control building 
Transformer was replaced on June 2, ’04.  The computer room power fire 
sprinkler shunt trip was tested prior to dropping power to the building. 
A bypass test switch for this system was also installed.

Shop Space/EVLA cold storage bldg.  A 5,000 sq. ft. metal building will 
be erected NE of the Generator Building. Once EVLA storage requirements 
are ended, this building may be used for shop space.  Foundation work 
will begin soon after rebar and material arrives.  The building had an 
8-12 week delivery and is scheduled for completion by the end of August. 
  Several persons from the construction crew will have to be trained and 
certified to operate the manlift.  Dean will do the digging for the 
foundation work.

WATER TANK REPAIR   Water tank repairs were completed on June 3, 04.

SAFETY HANDRAIL ON ROOF STORAGE AT AAB  A safety rail is required around 
the perimeter of the roofs of several AAB shops since they are being 
used for storage of materials.
The handrails are in place and only need to be painted.

CONCRETE TIMBERS
The track crew has built prototype concrete timbers to replace wooden 
timbers which are used at every intersection that accesses an antenna 
station. The original wooden timber design is a high failure design and 
timbers and planks are often broken under the weight of a transporter 
carrying an antenna. Timbers on hand are exhausted; we will begin 
repairing intersections with concrete timbers.  A concrete slab for 
making concrete timbers has been poured and Jigs for fabrication of 
concrete timbers will be assembled soon. Material costs for actual 
concrete timbers will be charged to the Track Budget account.

AZ BEARING Pocket Mill- the AZ Bearing Pocket Mill is used to machine 
the antenna azimuth bearing pocket.  At best the mill will currently 
achieve an accuracy of around .008 inches or .009 inches of tolerance. 
The spec calls for less than a .012 inch tolerance.  The use of a 
different bearing on the mill would achieve a higher degree of accuracy 
for milling the pocket.  If the new mill bearing can be purchased with 
our current budget we will replace it before the next bearing change.

EVLA Status
E Cole ---1.) Turning over EVLA overhauled antennas to Ops.  A final 
acceptance check list will be issued for EVLA antennas.  This final 
acceptance checklist when completed signifies the handing over of and 
antenna from Construction to Operations.
2.) An Electrical Survey will be done on antenna 14 to collect empirical 
data for estimating total antenna power consumption.  This survey will 
be done after Antenna 14 is fully outfitted and in full operation.
3.)  EVLA coordination— updates and Changes to the EVLA schedule will be 
handled through the Division heads

Stanzione--- UPS usage after the new correlator arrives is a subject 
that will need investigation. The new correlators will contain their own 
backup power and modcomp computer power requirements are projected to be 
minimal.

Serna--- EVLA manpower requirements— Estimates show that 1.25 Antenna 
Mechanic FTE (Full Time Employee)  is required to outfit each antenna 
EVLA antenna per year;  Approximately .31 FTE Electricians for each 
antenna per year and .25 HVAC technicians per antenna per year. 
Upcoming EVLA electrical work necessitates the hiring of an Electrician 
as soon as possible.

EVLA power requirements—Recent estimates for EVLA power requirements for 
Antennas and the Correlator indicate a huge impact on the entire 
electrical system, including exceeding the capacity of the two main VLA 
transformers (SEC and Generator) and possible fuse coordination along 
array arms and hatch gear equipment.  Current EVLA estimates double the 
Antenna load and increase the correlator load by 5 times early 
projections.  New operating procedures for load shedding under generator 
power may be necessary.  The existing high voltage power cable will 
handle up to 2.8 megawatts. Measurements for the antenna load will be 
done on Antenna #14 when it is fully loaded to get empirical data to use 
in estimating load requirements.

ES Division Fiber Lab work will be complete in about 2 weeks.  The fiber 
group is expected to move in by the end of July.

Quarterly Report Update      P. Lindsey
Quarterly report is due.  Patty will distribute forms for updating. 
Please update & return to Patty ASAP.

August also. Greg Hendley will take the State license exam later this year.


OTHER Discussion (Other)

Announcements:
Due to the Business office, Human Resources, Purchasing and Fiscal 
moving to the AOC West, a request has been made to have a separate mail 
box and bag for Administrative/Purchasing mail to be delivered to the 
AOC West building.  This would save from having to sort the mail at the 
AOC and expedite delivery to the AOC West.  A separate box will be 
placed in the Control Building and the mail from all other buildings 
will be sorted by the secretarial staff at the Control building. 
Persons who work at the control building should address and place all 
mail going to the AOC West building in the new AOC west mailbox.   The 
AOC West mail will be included in the regular AOC bag but will be 
contained in a separate envelope.  If you are not sure who should be 
addressed for AOC West Building check the telephone list to see what 
building that person is located in.

PT & MK Rail.  Pie Town Rail work is completed.  MK Rail work will occur 
July 21 through August 8.   If personnel traveling to MK have never 
traveled for NRAO to high altitude sites they must attain the High 
Altitude Training Certification; 1) Take a high altitude physical exam 
and provide copy of the physician’s statement, 2) View the high altitude 
training video within the last year.  3)  Indicate whether or not the 
traveler has basic first aid and/or CPR training, or specialized high 
altitude first aid, or CPR for remote locations.
