Minutes for the ES Division Coordination Meeting held on Tuesday, Jan.
31, 2006, at 10:30 am, in the LL CB conference room. Attending were Lew
Serna, Guy Stanzione, Ramon Gutierrez, Bob Broilo, Steve Aragon, James
Sullivan, Gene Cole, Brent Avery, Mark McKinnon, and Charley Chavez.
BUDGET — Still no real numbers but idea for a rate of spending is
forthcoming. Meanwhile supervisors are cautioned to only make essential
purchases until the "real" budget is known in a few weeks. Hold all
“new” projects until further notice. The EVLA is budgeted and work
should continue as scheduled.
VLBA TT Trips— since shipping the container to St Croix is extremely
expensive, we propose to ship a container one way, with all the parts
needed to repair the antenna and with tools needed for future tiger team
visits. The existing container is fairly beat up and should be replaced
since it may not be acceptable for shipping much longer. We would only
need to ship small boxes of tools and necessary parts for subsequent
visits. The cost estimate for doing this is around $10K. Shipping
costs for the container round trip is around $12K. Ramon will get cost
estimates for tools needed and purchasing a better container.
J. Thunborg is making an inspection trip to The St Croix this week in
order to evaluate the antenna in preparation for future maintenance.
A desired schedule for VLBA TT visits in FY 2006 is to complete KP, MK
and HN, with a possible visit to SC in the spring. Eric Carlowe
recommends that Tiger Team Visits to HN and MK be extended to 8 days.
The tentative VLBA schedule is to visit KP in early June, MK in late
July and HN in late Sept.
AZ Bearings-- Parts from the bearings removed from antennas are needed
for measuring and fitting of new parts and should be stored until they
are scheduled to be shipped to Rotek for repair. There are 2 good
Azimuth bearings on hand. One spare bearing should be maintained at all
times. Antenna 14, 16 & 18’s bearings will be shipped to Rotek for
possible refurbishment, at the rate of one per year, or as the budget
permits. If possible we should ship all bearings to Rotek to save on
shipping. There is an 8-9 week lead time for delivery on a refurbished
bearing.
Antenna 26’s bearing will be changed next and is scheduled to occur in
summer of FY2006 (possibly as early as May). An estimated three weeks
in the AAB are required before a bearing change can occur. Grease
samples show that antennas 26, 10, 20, are good candidates for the next
bearing changes.
NEW PROJECTS:
ACU Modification-- A new ACU that replaces the ACU in its entirety is
desirable. The new ACU would hopefully improve the position loop
response, improve reliability and replace the obsolete components in the
current ACU. A PLC (Programmable Logic Controller) based upgrade would
cost around $3K per antenna. EVLA has funded the prototype and design
work is ongoing. This remains a low priority project but if funding
becomes possible the priority may be elevated. No funding commitments
funding commitments have been made for retrofitting of antennas.
Control building Stairways—The Control Building Stairways will be
replace due to repeated unsuccessful attempts to prevent their rusting.
The stairways will be replaced with an improved design conforming to
ADA. Estimated cost to do this for both stairways is $12K. The EPO
Division contributed $6K towards this project while ES division will
carry the remaining cost. Materials have been ordered and drawings are
being sent to the Machine Shop and the Weld shop for fabrication of
parts. The stairs are due to be shipped next week. A new concrete
landing will have to be poured at the base of the eastern stairway.
LWDA (Long Wave Development Array)— The University of New Mexico and the
Naval Research Laboratory are leading a research project called the Long
Wavelength Demonstrator Array, which will be installed within the VLA
site central square mile. ES Division has provided access to the site
and installed a fiber optic cable that will be connected to VLA’s west
arm trunk at CW7. No further work by the ES Division is planned at this
time. Fiber terminations at CW7 should be completed by the end of
February by the fiber group.
Fire Station- The new Fire truck will not fit inside the existing fire
truck bay. The fire truck should be kept indoors to prevent the
freezing of pumps. Construction of a new bay is in progress and should
be completed soon. The ambulance is now housed in the old fire truck bay.
190 MHz Receiver System—The maximum support available from E/S Division
for cherry picker support is 8 hrs per week. An NRAO employee who is
knowledgeable in cherry picker operations or receiver installation must
be present at the antenna at the appropriate times for the installation
of the 190 MHz receiver. Support for this project continues.
Transporter Axles – The transporter axles are exhibiting several cracks
which are being rubbed out to prevent propagation of the cracks. This
is a temporary fix as more cracks will eventually reappear. These axles
should be replaced in the next 10 years with axles made of a different
material and design to increase their life. They are currently lasting
about 12-14 years and were last replaced in 1992. There are 12 axles
per transporter and each axle will cost around $3K to replace. There is
one spare axle of the existing design available. A plan to purchase 3
newly designed axles per year to replace all transporter axles in 8
years time is being proposed. It is worthwhile to investigate the cost
of having these built up at one time by an outside shop.
The last inspection of a “repaired” axle, in service for about 2 years,
revealed no cracks.
VLBA FRM Drives— The VLBA is running out of spare FRM motors due to
obsolescence. The current drive system utilizes three motors. Field
Techs are changing to a two motor drive system which should free up
motors for spares. Jim Ruff has proposed a new drive system for the
VLBA FRM’s. It is believed that the drive amplifiers proposed for the
new VLBA system will work with the VLA stepper motors. This project is
on hold until all budgetary numbers in (about a months time). The cost
to build a prototype is around $15K. The cost to retrofit all VLBA
sites is around $300K.
VLBA Watch Spring Cable Wraps— The VLBA Pie Town watch spring cable wrap
has been replaced with an EVLA type watch spring wrap at a cost of
around $300. It is an improvement over the current VLBA watch spring
wraps. The cable wrap has undergone a successful evaluation period and
will be installed at all VLBA Sites.
VLA Counterweights-- The VLA Antennas are Dish Heavy by about 7,000
foot pounds. An EVLA antenna needs to be counterweight tested with all
EVLA equipment installed to make sure of the actual amount of dish
counterbalance we need. Someday Green Bank may surplus the GBT steel
rail. At that time they have agreed to give us their surplus steel for
use as counterweight on VLA antennas.
VLBA Gearbox and Wheel Assy. Two Wheel assemblies are built for FY2006.
Also there should be enough spares to repair the spare VLBA Gearbox
that has been cannibalized. Brent Avery will check to see if the parts
have been expensed. If the parts have been expensed the gearbox should
be restored. If the parts have not been expensed we will wait a couple
of weeks to see what our budget is before we proceed. Brent Avery will
check the status of the parts in the warehouse.
Smoke Detectors: A Control Building “addressable smoke detector” audit
and replacement has been made in order to maximize savings on
programming costs. Glen and Bob have conducted a survey and detectors
have been ordered. Installation is in progress. Programming of the Fire
system to accommodate the detectors will take place when the Shielded
Room Fire protection is added.
Ballast Cars— Two ballast cars have been purchased through a special
fund at a cost of $16.8k each. The purchase of the ballast cars will
eliminate the need to run the high maintenance and costly dump trucks
for track work. The mechanical repairs to the two ballast cars have been
made and the cars are ready for a test drive. A test for proper braking
and a test of the capacity of ballast that can be hauled will occur this
week.
EVLA STATUS
Peter Napier took on a job with ALMA and A search committee is charged
with finding a replacement for Peter Napier. The process will take
several months. A replacement may be named by June. Mark McKinnon is the
interim EVLA Project leader.
Correlator Room-- Stanzione— Water Supply Plumbing work is in progress
at this time by a contractor. HVAC will finish the sprinkler plumbing
when the contractor leaves. Other work remaining is flooring, Electrical
wiring and Lighting. A modification of the Shielded room doors is being
designed to prevent accidental injury to personnel during the automatic
closure of the doors.
EVLA Antennas: E Cole-- Antenna 24 has entered the AAB for overhaul. If
ant 24 is finished by mid April Antenna 26 will be brought in for a
bearing change/EVLA outfit. EVLA Antenna 24 will have to be completely
outfitted with working electronics, before the next antenna can come
into the AAB.
Feed Tower-- Gutierrez-- There is a problem with fitting all the feeds
in the feed circle of the tower due to the size of the new X-band feed.
A feed tower was built and adjustments were made to resolve fitment
problems. Antennas with the old X-band feeds (first 4 EVLA antennas)
will be retrofitted at the end of the EVLA outfitting cycle. There are
only 2 prototype X-band feeds available at this time but all future feed
towers will be constructed to accommodate the new feeds.
SCHEDULING CALENDAR ON LINE— E. Cole-- Procedures to improve antenna
accessibility and to avoid accidental antenna movement are in effect.
EVLA Antennas that have been outfitted in the AAB and are being
“delivered” for electronic outfitting can be remotely controlled. In
order to prevent accidental antenna movement, antennas will be locked
out until such time that movement is authorized. Rudy Latasa (Cryo
Group) will be responsible for the Lockout.
Antennas that have been deemed electronically outfitted will go into a
“Test Phase”. In the Test Phase the antenna is not locked out and can
be remotely controlled. Employees are reminded to use caution and to
exercise proper Lock Out Tag Out (LOTO) procedures when visiting
antennas. Employees should always contact Operations prior to visiting
any EVLA antennas that are in Electronic outfitting or the Test Phase.

SAFETY REPORT... James Sullivan
Twelve Accidents occurred in 2005. No new accidents and one new incident
reported so far this year. A Lock Out Tag Out (LOTO) safety training
session was held at the VLA on Jan. 26. The next training session
occurs on Feb. 23. There will be CPR training for the Electricians and
the PT crew. The CPR training will be administered by R Murillo, P
Madigan and J Sullivan. Much of the hazardous waste has been removed
and the remainder will be removed soon. A report from the EPA
inspection indicates several problems with our hazardous material
disposal site which need to be addressed.
ANNOUNCEMENTS:
PEPS – Begin April 1
2005 PERFORMANCE EVALUATION PROCESS TIME LINE
April 1 Supervisors begin soliciting information about employee work
performance from other supervisors and coworkers. Supervisors will
conduct brief individual or group meetings with employees to discuss the
upcoming process and to distribute copies of the appropriate performance
appraisal forms including a list of goals that were set last year.
Exempt employees are required to complete a self-appraisal. Although
nonexempt
employees are not required to complete a self-appraisal, they should be
given a copy of the non-exempt appraisal form and encouraged to complete
it.
Exempt employees begin completing the appraisal form by identifying any
changes in their key responsibilities and reporting on their progress
toward achieving the goals set last year. Any other significant
accomplishments they may have had during the year should also be
identified. Finally employees should identify goals for next year.
May 1 Due date for employees to return the self-appraisal forms to
their supervisors with the appropriate sections completed. Supervisors
begin writing employee evaluations based on their observations, coworker
feedback, and the self-appraisal completed by the employee. Supervisor
reviews the draft goals for the coming year and modifies as appropriate.
June 1 Supervisor reviews completed performance appraisal forms with
division
head and receives approval. Supervisor begins scheduling and holding
evaluation meetings with employees.
June 31 Due date for all evaluation meetings to be concluded and
appraisal forms signed by the employee. Employees should be given
sufficient time (at least 24 hours) to review and comment on the
evaluation. Based on information provided by the employee, Supervisors
should make corrections and changes as appropriate.
July 5 All of the original completed and signed appraisal forms must be
forwarded to the appropriate Human Resources Office. A copy of the
signed appraisal should be provided to the employee.
