A project phase where construction work is ongoing while equipment or materials are still in transit to the site. Subcontractors must coordinate mobilisation and scope carefully to avoid costly downtime waiting on delayed deliveries. Billing milestones and crew schedules should account for this overlap.
Transit-Active Construction
Related Terms
ERCOT (Electric Reliability Council of Texas)
IndustryThe grid operator managing Texas's independent power network, separate from national grids. Subcontractors working Texas energy projects must understand ERCOT rules govern power availability and outages. Grid instability events like Winter Storm Uri directly impact field site operations and project timelines.
Major Projects Office (mpo)
IndustryA centralised owner or operator division that oversees large-scale capital projects and manages contractor relationships. Subcontractors typically submit bids, invoices, and compliance documents through the MPO rather than individual site teams. Knowing your MPO contact streamlines approvals, change orders, and payment processing.
Mmtpa (million Metric Tons Per Annum)
IndustryA measure of annual production or throughput capacity at LNG, mining, or pipeline facilities. Subcontractors use it to gauge project scale and estimate long-term scope of maintenance or construction work. Higher MMtpa ratings typically signal larger crews, longer contracts, and more equipment requirements.
Liquefaction Train
IndustryA complete processing system that cools natural gas into liquid LNG (Liquefied Natural Gas) for storage and transport. Each train is a major construction and maintenance scope, often requiring large, specialised subcontractor workforces. Shutdowns and turnarounds on these units are high-value contracts with strict schedule demands.
Compression Expansion
IndustryA growth phase where an operator scales up gas compression infrastructure, creating demand for additional field service crews and equipment. Subcontractors should anticipate increased work orders for installation, commissioning, and maintenance. Securing standing agreements before expansion begins helps lock in preferred vendor status.
CIPP (Cured-in-place Pipe)
IndustryA trenchless pipe rehabilitation method where a resin-saturated liner is inserted into a damaged pipe and hardened in place. Subcontractors typically provide specialised crews, inversion or pull-in equipment, and UV or steam curing systems. Common in municipal, oil and gas, and industrial pipeline maintenance scopes.
