Minimum Work Program

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.

A high-voltage transformer exceeding 100 MVA used in electrical substations and large industrial facilities. Subcontractors are often mobilised for LPT installation, maintenance, or emergency replacement work. These units require specialised rigging, permitting, and certified electrical crews due to their size and criticality.

A formal period when a pipeline operator solicits capacity commitments from shippers before building or expanding a line. For subcontractors, it signals upcoming construction and maintenance work. Winning bids during this phase often trigger mobilisation timelines and crew planning.

A large-diameter pipeline that moves water, gas, or other fluids over long distances at high pressure. Subcontractors are often hired for installation, inspection, or maintenance work on these lines. Strict pressure ratings and material specs govern all field work.

The full replacement or rebuild of damaged underground services such as water, gas, or electrical lines. Subcontractors are often mobilised after excavation damage or infrastructure failure. Scope typically includes trenching, pipe installation, backfill, and surface restoration.

A centralised surface facility that collects and processes production from multiple wells simultaneously. For subcontractors, it means larger, longer-duration scopes covering instrumentation, piping, and facility maintenance. Mobilisation costs are often shared across the site, improving job economics.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements
