Intelligent Traffic Systems work is structurally different from building-systems MEP. The workforce is Elektrohandwerk under BG-ETEM, Industriemontage under IG Metall ERA M-Tarif Bayern, MSR / SPS programmers and tunnel-safety crews. ITS sites are roads and tunnels, not Baustellen — pitching this buyer on SOKA-BAU exposure burns credibility.
Specialist pains include DGUV 113-014 tunnel-trained electricians with AGT G 26.3 respirator certification (almost no Indian / Gulf labour-pool exposure); DIN VDE 1000-10 Elektrofachkraft mandatory on every energised signal cabinet under DGUV V3; Autobahn GmbH supplier-qualification exposure on §21(2) GWB findings; and parent-company D.Lgs. 231/2001 (Mundys-style) flow-through from any DE-sub labour offence into Italian-bond disclosure.
