| Service | Method | Best Use Case | Detection Window |
|---|---|---|---|
| Pre-Employment and Entry Screening | Urine, saliva, and breath alcohol | Screening candidates before induction and site access | Short to long |
| Random Workforce Testing | Urine, saliva, and breath alcohol | Workforce deterrence and ongoing policy enforcement | Recent to short-term |
| For-Cause and Suspicion-Based Testing | Urine, saliva, and breath alcohol | Immediate response to behaviour or safety concerns | Very recent to short-term |
| Post-Incident Response | Urine, saliva, and breath alcohol | Evidence-led post-incident investigation support | Recent to short-term |
| Multi-Method Drug Testing | Urine, saliva, and breath alcohol | Layered programmes with different risk and detection needs | Short to extended |
| Policy Review and Reporting | Advisory and governance support | Policy redesign, reporting consistency, and escalation design | N/A |
Screening is delivered as point-of-care (POC) where applicable. Current urine cup workflow uses a 10-panel screen for Cannabis, Cocaine, Amphetamine, Methamphetamine, MDMA, Opiates (including Morphine/Heroin), Methadone, Benzodiazepines, Tricyclic antidepressants, and Barbiturates. Indicative urine detection is typically around 2-5 days after last use, with THC sometimes longer in frequent users. Non-negative POC screens should be confirmed through laboratory chain-of-custody testing; split-chamber cup design supports retained sample for confirmation.

FAQs
Common Questions from Construction Employers
What test type is most common on construction sites?
Urine and saliva testing are frequently used for workplace programmes, while breath testing is standard for alcohol screening. The right method depends on policy objectives and job role risk.
Can we run random testing legally and fairly?
Yes, where testing is supported by a clear policy, communicated process, and consistent application across relevant worker groups.
When should post-incident testing be used?
Post-incident testing is typically used after safety events, near misses, or significant breaches where objective evidence is needed as part of investigation and follow-up.
How often should testing be carried out?
Frequency depends on your risk profile, workforce size, and contractual obligations. Many organisations combine random testing with trigger-based and post-incident testing.
Do we need a dedicated drugs and alcohol policy?
A clear policy is essential. It defines testing triggers, consent, escalation, and decision pathways, reducing inconsistency and legal exposure.
Can testing be tailored for subcontractor-heavy projects?
Yes. Programmes can be scoped by site, package, and workforce category so principal contractor requirements and subcontractor obligations remain aligned.
What is needed on site to carry out testing?
In most cases we need a suitable private area for collection, a contact on site to coordinate worker flow, and clear access arrangements. We can advise in advance on space, welfare, and timing requirements based on the testing method being used.
Is screening delivered as point-of-care (POC) testing?
Yes, where applicable. Screening is commonly delivered as point-of-care (POC) testing with documented identity checks, sample handling controls, and escalation pathways aligned to policy.
What does the current urine cup panel screen for and what are indicative detection windows?
The current 10-panel urine cup workflow screens for Cannabis, Cocaine, Amphetamine, Methamphetamine, MDMA, Opiates (including Morphine/Heroin), Methadone, Benzodiazepines, Tricyclic antidepressants, and Barbiturates. Indicative urine detection is typically around 2-5 days after last use, with THC sometimes longer in frequent users. Non-negative POC results should be confirmed through laboratory chain-of-custody testing.
How quickly will we receive a quote response?
Most quote enquiries receive a first response within one business day. More complex multi-site requirements may take slightly longer while scope is reviewed.
Policy and Guidance
Recommended Focus Areas for Construction Testing Programmes
Strong programmes combine operational delivery with practical policy design. In construction environments, testing should be integrated into onboarding, supervision, and incident management workflows.
- Define clear reasons for testing: recruitment, random, for-cause, and post-incident
- Set role-based thresholds and responsibilities for site leaders and HR teams
- Train managers on procedure, documentation, and confidential communication
- Review programme outcomes regularly to improve safety and consistency
