Work Zone

A construction or industrial site equipped with sensors, cameras, and connected devices to monitor traffic, equipment, and worker movement in real time. Subcontractors operating in these zones must comply with data-sharing and equipment compatibility requirements set by the prime contractor. Non-compliance can result in site access delays or contract penalties.

A worker recognised by a client or regulator as having the training, experience, and authority to identify hazards and direct safe work. Subcontractors are often required to designate a Competent Person on-site before work begins. Failing to do so can result in work stoppages or lost contracts.

The process of renewing or repeating required safety, technical, or vendor approvals after they have lapsed or been revoked. Operators and prime contractors may require subcontractors to re-qualify before awarding new work. Failing to re-qualify on time can result in removal from approved vendor lists.

A contractual or regulatory rule requiring subcontractors to hire local workers, source materials locally, or partner with regional firms. Non-compliance can disqualify you from bidding or trigger contract penalties. Common on projects funded by governments or national oil companies.

The process of ensuring your company does not do business with individuals, entities, or countries under government-imposed trade restrictions. Subcontractors must screen clients, vendors, and partners against sanctions lists before signing contracts. Non-compliance can result in heavy fines, contract termination, or criminal liability.

Legally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure. Operators budget ARO years in advance, which can create late-project work opportunities for subcontractors. Understand how ARO timelines affect contract scope, since decommissioning work often has strict regulatory deadlines.
