Frontier Exploration
IndustryExploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.
AWP (Aerial Work Platform)
IndustryA powered, elevated platform used to lift workers and tools to height for maintenance, construction, or inspection tasks. Common AWP types include scissor lifts, boom lifts, and man baskets. Subcontractors must verify operator certification and equipment inspection records before mobilising an AWP on site.
CMMS (Computerized Maintenance Management System)
IndustrySoftware used to schedule, track, and document equipment maintenance and work orders on job sites. Subcontractors often must log completed maintenance tasks directly into a client's CMMS. Accurate entries protect you during audits and support invoicing for billable maintenance work.
Marine Construction
IndustryOffshore and nearshore infrastructure work including platform installation, subsea pipelines, and dock or jetty builds. Subcontractors often face strict vessel access requirements and marine safety certifications. Mobilisation costs and weather delays are major contract risk factors.
Npr-A (national Petroleum Reserve in Alaska)
IndustryA federally managed exploration zone on Alaska's North Slope, open to oil and gas development. Subcontractors working here face strict federal permitting, remote logistics, and seasonal access limitations. Mobilisation costs and compliance requirements are significantly higher than standard onshore projects.
Work Package
IndustryA defined bundle of tasks, drawings, and specs issued to a subcontractor for a specific scope of work. It sets the boundaries of your crew's responsibilities on a project. Work packages drive your billing milestones and progress claims.
