Pipeline Estimation

Pipeline (Linear) Cost Estimation

Pipeline estimating is different from Facility (Plant) estimating, as direct and indirect buckets have their own contents. Cost of Pipeline Projects are dependent on their route, terrain, and season of construction. Pipeline estimating mainly is based on it's crews for each activity. Typically, the cost is measured in units of Diameter-Inch-Mile (DIM) or per meter.

Typically, cost is calculated based on spreads. A Spread is the sub-division of total length of Pipeline; Pipelines of small length may have only one spread, whereas longer pipelines may have several spreads.

Some key sections of estimate are material, construction, land, engineering, line fill aka line-pack, and owner’s cost.
At higher-level construction is based on Base-lay, UPIs (Unit Price Items), and Ancillary costs. Base-lay cost is broken down to safety, right-of-way disposition, clearing, grading, stringing, bending, welding, joint coating, trenching, jeeping, lowering, cathodic protection, backfilling, crossings, buoyancy control, NDE, caliper pigging, tie-ins, commissioning, cleanup, reclamation, post mortem, and documentation.

Crew mix of labour, equipment (used for construction), and miscellaneous items are developed for each section listed above based on agreed upon shift schedule.

Estimating for Tailing Pipe and Froth Lines are calculated on the same principles of cross county Pipelines; however, the level of rigor required depends on the size and length of lines.

Along with preparing Pipeline estimates for our clients we also supply and support estimating tools, and develop ROT (rule of thumb) charts for multiple sizes and pressure. Please see our demo for more details.
