BKL ATCT GND CTLR BECAME CONFUSED WITH HANDLING TFC ON ARPT PREPARING FOR A SPECIAL EVENT WHEREIN THE NORMAL TXWYS WERE TEMPORARILY CLOSED AND 1 ACTIVE PARALLEL RWY WAS ALSO BEING USED FOR A TXWY.

Narrative

AFTER RECEIVING AN IFR CLRNC; WE CONTACTED THE GND CTLR AT BKL FOR TAXI. WE WERE TOLD TO HOLD ON THE RAMP AS THERE WAS NO TXWYS OPEN YET. BKL IS PREPARING FOR A SPECIAL EVENT; SO THE TXWYS ARE CLOSED AND THEY WERE USING RWY 6R AS A TXWY TO TAXI TO RWY 6L. THEY ALSO WERE USING RWY 6R AS AN ACTIVE RWY FOR SMALLER ACFT. WE WAITED ABOUT 5 MINS WHEN THE CTLR CALLED US TO TAXI TO RWY 6L VIA RWY 6R VIA THE ENTRANCE TXWY C THAT CAME INTO THE RWY 6R. CTLR SAID THAT THERE WERE MEN AND EQUIP WORKING ON THE CLOSED TXWY AND THAT THEY WOULD WAIT FOR US. THE FO READ BACK THE CLRNC AND WE PROCEEDED TO TAXI AS CLRED. AS WE TURNED WBOUND ON RWY 6R; I NOTICED A HELI APCHING THE RWY FROM THE W. I STOPPED THE ACFT AND WAS TELLING THE FO TO QUESTION THE CTLR'S INTENTIONS WHEN CTLR STARTED YELLING THAT WE DID NOT HAVE CLRNC TO BE ON THE RWY. WE REPLIED THAT WE CERTAINLY DID; CTLR HAD JUST GIVEN US THE CLRNC TO TAXI TO RWY 6L VIA RWY 6R. CTLR CLRED THE HELI TO THE PAD AND WITHOUT SAYING ANYTHING ELSE; CLRED US TO PROCEED TO TAXI TO RWY 6L. THIS CTLR WAS VERY CONFUSED; FREQUENTLY MISDIRECTING OTHER ACFT AND CALL SIGNS. CTLR WAS ALSO INVOLVED IN AN EARLIER INCIDENT IN THE SAME DAY WITH US AND THAT IS NOTED ON ANOTHER RPT.
