Narrative:
On aug/xa/05 at approximately XA40Z; I was working the ground control east position combined with ground control west at las ATCT. A king air BE20 requested taxi instructions. I told the BE20 to expect runway 25R; that both runway 19R and runway 19L were closed to taxi via taxiway H to taxiway south cross runway 19R then to turn on runway 19L to taxiway west. A short time later; the pilot of the king air asked if runway 19R was really closed. I observed traffic (a B737) on short final runway 19R. I instructed the BE20 to hold short of runway 19R and then asked the other controllers if runway 19R was closed. I was told no. I thanked the pilot for asking and instructed him to taxi to runway 19R. I had not properly pre-briefed myself; although the sia was updated correctly. When the relieving controller briefed; I understood incorrectly runway status. I understood that he was taking all aircraft to runway 25R from the west side of the airport. He briefed that (because of construction) he was taxiing to runway 25R via taxiway south cross runway 19R turn down runway 19L via taxiway west; taxiway G; taxiway C to the runway. The FAA requires that I; as a supervisor; need 8 hours a month to maintain currency. That sometimes may only be a few mins on a given position. As long as I get a combined total of 8 hours; I am good to go. I feel that I need more time so I have started to put emphasis into position time and that I shall pre-brief properly before I state I am ready to assume an operational position. I also will mentor my crews to do the same thing. I am truly grateful to the pilot who asked me of the status of runway 19R before he crossed in front of landing traffic.

Title: LAS SUPVR CTLR FAILS TO PROPERLY SELF-BRIEF REGARDING RWY CLOSURES AND ISSUED RWY XING CLRNC TO TAXIING ACFT WITH TFC ON SHORT FINAL.
Narrative: ON AUG/XA/05 AT APPROX XA40Z; I WAS WORKING THE GND CTL E POS COMBINED WITH GND CTL W AT LAS ATCT. A KING AIR BE20 REQUESTED TAXI INSTRUCTIONS. I TOLD THE BE20 TO EXPECT RWY 25R; THAT BOTH RWY 19R AND RWY 19L WERE CLOSED TO TAXI VIA TXWY H TO TXWY S CROSS RWY 19R THEN TO TURN ON RWY 19L TO TXWY W. A SHORT TIME LATER; THE PLT OF THE KING AIR ASKED IF RWY 19R WAS REALLY CLOSED. I OBSERVED TFC (A B737) ON SHORT FINAL RWY 19R. I INSTRUCTED THE BE20 TO HOLD SHORT OF RWY 19R AND THEN ASKED THE OTHER CTLRS IF RWY 19R WAS CLOSED. I WAS TOLD NO. I THANKED THE PLT FOR ASKING AND INSTRUCTED HIM TO TAXI TO RWY 19R. I HAD NOT PROPERLY PRE-BRIEFED MYSELF; ALTHOUGH THE SIA WAS UPDATED CORRECTLY. WHEN THE RELIEVING CTLR BRIEFED; I UNDERSTOOD INCORRECTLY RWY STATUS. I UNDERSTOOD THAT HE WAS TAKING ALL ACFT TO RWY 25R FROM THE W SIDE OF THE ARPT. HE BRIEFED THAT (BECAUSE OF CONSTRUCTION) HE WAS TAXIING TO RWY 25R VIA TXWY S CROSS RWY 19R TURN DOWN RWY 19L VIA TXWY W; TXWY G; TXWY C TO THE RWY. THE FAA REQUIRES THAT I; AS A SUPVR; NEED 8 HRS A MONTH TO MAINTAIN CURRENCY. THAT SOMETIMES MAY ONLY BE A FEW MINS ON A GIVEN POS. AS LONG AS I GET A COMBINED TOTAL OF 8 HRS; I AM GOOD TO GO. I FEEL THAT I NEED MORE TIME SO I HAVE STARTED TO PUT EMPHASIS INTO POS TIME AND THAT I SHALL PRE-BRIEF PROPERLY BEFORE I STATE I AM READY TO ASSUME AN OPERATIONAL POS. I ALSO WILL MENTOR MY CREWS TO DO THE SAME THING. I AM TRULY GRATEFUL TO THE PLT WHO ASKED ME OF THE STATUS OF RWY 19R BEFORE HE CROSSED IN FRONT OF LNDG TFC.
