Drug testing for construction employers and job sites
Project schedules, temporary sites, and safety culture—collections that respect the job while keeping policy enforceable.
Construction employers test for regulatory drivers, client requirements, union agreements, and internal safety culture. Crews are spread across active sites, and clinic trips can burn hours the schedule does not have.
Mobile and on-site collections let superintendents and safety leads keep testing on the program without pulling craft off the job longer than necessary—while still maintaining chain of custody and donor dignity.

Typical testing needs on construction projects
Reasonable suspicion and post-incident testing spike when equipment, heights, or public exposure raise the stakes. Policies often require prompt testing; logistics matter as much as policy language.
DOT-covered operators (hauling, equipment transport where applicable) may need DOT drug and alcohol collections alongside non-DOT craft under a separate company policy. Random programs—DOT or handbook-driven—need batching that respects gate access and site safety rules.
Large mobilizations, turnaround windows, and owner-mandated screening may require high-volume on-site days with multiple collectors.
Why on-site and mobile testing works for construction
Job sites change; clinics do not move with the project. Collectors can stage in trailers, site offices, or designated areas once privacy and restroom or observation requirements are addressed.
Supervisors stay close to production and can manage donor flow, breaks, and trade coordination—reducing no-shows and confusion compared to sending individuals to off-site labs.
Program types relevant to construction employers
We frequently support post-accident and reasonable suspicion collections, random programs for DOT and non-DOT populations, mobile drug testing, and breath alcohol workflows when alcohol is part of the policy or regulation.

Questions from this sector
- Can you test at temporary or remote job sites?
- Often yes. Feasibility depends on access, privacy, safety, and specimen requirements. Share site details in your quote request for planning.
- Do you support multi-employer GC sites?
- Yes, when each employer authorizes its own donors and program rules. Coordination with site security and site leadership is essential.
- What about DOT vs non-DOT on the same project?
- Separate program rules by employee category. We confirm who is covered under which plan before collections begin.
