A drilled or excavated hole through soil, rock, or existing structure. Subcontractors are often scoped to complete a specified number of bores per shift. Bore diameter and depth directly affect equipment selection and crew sizing.
Bore
Related Terms
Trenchless
IndustryA method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.
Full-Depth Reclamation
IndustryA road rehabilitation method where the full pavement structure is pulverised and mixed with the subgrade to create a stabilised base. Subcontractors use specialised reclaimers and stabilisers to complete the work in a single pass. It is common on oilfield lease roads and remote access routes requiring cost-effective repair.
High-Impact Well
IndustryA well with significant technical complexity, cost, or strategic value to the operator. For subcontractors, these projects typically involve stricter oversight, specialised equipment, and higher performance expectations. Mobilisation windows and crew qualifications are often scrutinised more closely.
Laser Surface Ablation
IndustryA surface preparation method using focused laser energy to remove rust, coatings, or contaminants from metal. Subcontractors use it as a cleaner alternative to sandblasting on pipelines and structural steel. It reduces waste disposal costs and meets strict environmental site requirements.
Cavern Storage
IndustryUnderground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.
Progressive Design-Build
IndustryA project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.
