A formal engineering assessment that determines whether aging or damaged equipment is safe to keep operating. Subcontractors may be required to conduct or document FFS evaluations before resuming work on pressure vessels, pipelines, or structural components. Results directly affect your scope of work, liability exposure, and project timelines.

A court order that immediately halts a specific action, such as work stoppage disputes or lien enforcement, pending a full hearing. Subcontractors may face a TRO if a general contractor seeks to block liens or contract terminations. It is a short-term legal tool, typically lasting days, until a judge rules further.

A mandatory stop in work where a client or inspector must review and sign off before the subcontractor can proceed. Missing a hold point can void certifications or trigger costly rework. Always confirm hold points during project kickoff to avoid schedule delays.

A U.S. federal agency that funds and regulates public transit infrastructure projects. Subcontractors working on federally funded transit construction must meet strict FTA compliance requirements. These include labour standards, safety protocols, and Buy America provisions for materials.

Formal verification that a subcontractor meets a client's safety, technical, or insurance standards before being awarded work. Most major operators require active certification through third-party registries such as ISNetworld or Avetta. Lapsed certification can result in immediate removal from approved vendor lists.

Mandatory safety systems used to prevent trench walls from collapsing on workers during excavation. Common methods include shoring, sloping, and trench boxes.
