A method of tracking an underground drill head's position by walking the surface above it with a handheld receiver. The receiver picks up a signal from a transmitter housed in the drill head. Subcontractors use this to guide directional boring and confirm depth in real time.

MEP (Mechanical, Electrical, and Plumbing)
IndustryRefers to the three core building systems subcontractors install and maintain on construction and industrial facility projects. MEP scopes are often divided among specialised trades, each holding separate contracts or working under a prime contractor. Understanding MEP divisions helps subcontractors define their scope, avoid overlap disputes, and price work accurately.
Thermal In-Situ
IndustryA method of extracting heavy oil or bitumen by injecting steam underground to heat and mobilise the resource. Common techniques include SAGD (Steam Assisted Gravity Drainage) and CSS (Cyclic Steam Stimulation). Subcontractors support these operations through facility construction, pipefitting, instrumentation, and ongoing maintenance work.
Mmcf/d (million Cubic Feet Per Day)
IndustryA measurement of natural gas production or flow volume, used to describe the output capacity of a well, pipeline, or facility. Subcontractors use this figure to gauge job scale, equipment sizing, and crew requirements. Higher MMcf/d ratings typically signal larger scopes of work and longer contract durations.
SPMT (Self-propelled Modular Transporter)
IndustryA multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.
Baseload Energy
IndustryThe minimum level of power demand that a facility or site requires continuously, around the clock. For subcontractors, it determines whether remote worksites need dedicated generators or grid connections. Stable baseload requirements help crews plan equipment fuel consumption and maintenance schedules.
Geothermal Brine
IndustryHighly mineralised, hot saltwater extracted from underground geothermal reservoirs during energy production. Subcontractors handling it must follow strict corrosion control and PPE protocols. Disposal and handling are heavily regulated due to its chemical content.
