From lserna at aoc.nrao.edu Wed Jun 23 16:56:52 2004 From: lserna at aoc.nrao.edu (Lew Serna) Date: Wed, 23 Jun 2004 14:56:52 -0600 Subject: [Escoordminutes] ES Div Coord. Minutes - June Message-ID: <40D9EE94.3070700@aoc.nrao.edu> 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. SAFETY REPORT ...James Sullivan There has been a total of twelve (12) Accident/Incidents reported to date, 9 accidents attributed to the ES Division. The scheduled May all hands safety meeting/session was held on June 3 due to scheduling conflict (43 employees were in attendees). The next safety session is scheduled for Thursday June 24. Safety training and refreshers training on man-lifts are to be scheduled in the near future. Congratulations to Phillip Sanchez, Lonnie Guin and Greg Hendley for their accomplishments. Phillip completed the Basic EMT course and will take the State license exam in August. Lonnie and Greg have completed the EMT Intermediate course. Lonnie will take his State license exam in 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. Announcements: NRAO Director, Fred Lo will be here the week of June 28. He will call all hands meeting with electronics staff on the morning of July 1 (Thursday), and with VLA site staff in the afternoon of the same day. Time to be announced. A Retirement party for Jim Rexrode will be held on Thursday July 22. Jimmy & Lefty will work their last day on that Thursday,
