Questions from employers in this region
Intel's Chandler fabs are a multi-year, multi-billion dollar construction project — how do you manage ongoing CDL testing?
Intel's Fab 52 and Fab 62 construction involves continuous CDL hiring across dozens of subcontractor tiers over multiple years. We set up standing pre-employment and random testing programs for each prime and subcontractor employer tier — providing on-site collections at the construction staging areas as workforces rotate throughout the project timeline.
Semiconductor fab construction uses highly specialized CDL carriers for cleanroom equipment — what FMCSA requirements apply?
CDL operators transporting cleanroom equipment, specialty gases, and semiconductor manufacturing materials to Intel and TSMC fab campuses in commercial motor vehicles over 26,001 lbs are subject to FMCSA Part 382. These specialty carriers require the same pre-employment and random testing documentation as any other regulated CDL employer.
