Narrative:

Atcs, working ground control. Runway 13R closed for construction/resurfacing. Vehs operating on runway 13R. Runway 13L primary active. Agreement from airport operator (city of dallas) to hold runway 18 inactive and we would advise safety representative when we required (usage of) runway 18. Cpr X taxied from FBO requesting runway 18. Coordinated with safety representative, advising we had a departure for runway 18. He acknowledged!! Local (tower) controller scanned as he advised me that the cpr X would be rolling south. I scanned the runway and returned with the acknowledgement of 'roll south.' runway 18 was clear, free of any traffic at all. As cpr X commenced takeoff roll and was already approximately 1000' down runway 18, a pickup pulled out onto runway 18 at the intersection of runway 13R. As the tower controller attempted to advise the aircraft of the veh on the runway, another construction veh, a sort of crane, was following the pickup onto the active runway 18 (at the same intersection). During these moments I was actively attempting to advise the safety representative of the departing cpr X, he having the only radio. The cpr X pilot got the aircraft airborne midfield, approximately +/-1000' prior to the intersection where the vehs were crossing. Apologies from the safety representative. We (controllers) had requested that runway 18 be either closed or restr to arrs only, with the last up to 1000' closed from the intersection south. These requests were refused. Apparently expediency in completion of a construction project, or at least easiness for vehs, is more important than aircraft/pilot safety.

Title: UNAUTH RWY INCURSION BY ARPT VEHICLE. LESS THAN STANDARD SEPARATION.

Narrative: ATCS, WORKING GND CTL. RWY 13R CLOSED FOR CONSTRUCTION/RESURFACING. VEHS OPERATING ON RWY 13R. RWY 13L PRIMARY ACTIVE. AGREEMENT FROM ARPT OPERATOR (CITY OF DALLAS) TO HOLD RWY 18 INACTIVE AND WE WOULD ADVISE SAFETY REPRESENTATIVE WHEN WE REQUIRED (USAGE OF) RWY 18. CPR X TAXIED FROM FBO REQUESTING RWY 18. COORDINATED WITH SAFETY REPRESENTATIVE, ADVISING WE HAD A DEP FOR RWY 18. HE ACKNOWLEDGED!! LCL (TWR) CTLR SCANNED AS HE ADVISED ME THAT THE CPR X WOULD BE ROLLING S. I SCANNED THE RWY AND RETURNED WITH THE ACKNOWLEDGEMENT OF 'ROLL S.' RWY 18 WAS CLR, FREE OF ANY TFC AT ALL. AS CPR X COMMENCED TKOF ROLL AND WAS ALREADY APPROX 1000' DOWN RWY 18, A PICKUP PULLED OUT ONTO RWY 18 AT THE INTXN OF RWY 13R. AS THE TWR CTLR ATTEMPTED TO ADVISE THE ACFT OF THE VEH ON THE RWY, ANOTHER CONSTRUCTION VEH, A SORT OF CRANE, WAS FOLLOWING THE PICKUP ONTO THE ACTIVE RWY 18 (AT THE SAME INTXN). DURING THESE MOMENTS I WAS ACTIVELY ATTEMPTING TO ADVISE THE SAFETY REPRESENTATIVE OF THE DEPARTING CPR X, HE HAVING THE ONLY RADIO. THE CPR X PLT GOT THE ACFT AIRBORNE MIDFIELD, APPROX +/-1000' PRIOR TO THE INTXN WHERE THE VEHS WERE XING. APOLOGIES FROM THE SAFETY REPRESENTATIVE. WE (CTLRS) HAD REQUESTED THAT RWY 18 BE EITHER CLOSED OR RESTR TO ARRS ONLY, WITH THE LAST UP TO 1000' CLOSED FROM THE INTXN S. THESE REQUESTS WERE REFUSED. APPARENTLY EXPEDIENCY IN COMPLETION OF A CONSTRUCTION PROJECT, OR AT LEAST EASINESS FOR VEHS, IS MORE IMPORTANT THAN ACFT/PLT SAFETY.
