Midstream
Digital Precision for Pipelines, Compressor Stations, and Gas Plants
Midstream projects happen in live facilities, often with outdated drawings and unknown field conditions.
OnSite3D helps operators across Western Canada and the US Gulf Coast verify conditions before fabrication using 3D laser scanning, scan-to-fabrication workflows, and VDC coordination. The result is better fit-up, fewer field surprises, and accurate digital records that last beyond the project.
Midstream Modifications Fail at the Same Point Every Time
Most brownfield tie-ins and compressor station upgrades start with the same problem: no one fully knows what’s actually in the field. Drawings are outdated, past modifications were never captured, and crews are left to figure it out during construction.
That disconnect between drawings and reality is what drives rework, schedule delays, and non-fitup issues. When a spool doesn’t fit, it means another fabrication cycle, another mobilization, and more downtime.
OnSite3D helps eliminate that risk before work begins.
From Compressor Stations to 83-Site Asset Programs
OnSite3D works across the full range of midstream scopes — from a single tie-in on an active compressor station to facility-wide asset programs spanning 83 sites.
As-Built Capture & Digital Twin
High-accuracy 3D laser scanning of existing midstream infrastructure — compressor stations, pipelines, metering stations, and associated piping and structural systems. Results hosted on WebShare and accessible to your operations and engineering teams. One verified source of truth, replacing legacy drawings.
Scan-to-Fabrication
Point cloud registered against the design model, deviations flagged before fabrication. Replacement piping, structural components, and tie-ins fabricated in our RoboFab facility — ABSA AQP certified. Laser QA before every piece ships. Arrives on site ready to install.
VDC Coordination & Clash Detection
Our VDC team registers the point cloud against the design model, identifies constructability issues, and resolves clashes at desk cost — before the shutdown window opens. Virtual assemblies validate fit-up. Sequencing confirmed before crews mobilize.
Shutdown & STO Support
Pre-shutdown scope validation, in-shutdown dimensional support for tie-in issues, virtual assemblies to confirm fit-up before the window opens, and post-shutdown as-built to capture the updated record for the next cycle.

Why Midstream Operators Choose OS3D
Continuous Operations Discipline
Midstream infrastructure doesn’t have scheduled outage windows the way a refinery does. Modifications happen in tight maintenance slots against operating pressure. Our workflow is built around that constraint — conditions verified before fabrication, parts delivered to fit, no surprises when the window opens.
Above-Grade Infrastructure Expertise
OnSite3D’s scan teams are experienced in capturing the as-built state of midstream infrastructure at the level of detail fabrication requires — including congested pipe racks, valve stations, and compressor skids.
Fabrication That Travels
ABSA AQP certified across CS, SS, Monel, and Inconel. Laser QA on every component before it ships. We’ve supported midstream projects across Western Canada and the US Gulf Coast. If it can be shipped, we can fabricate it to fit.
One Scope, One Invoice
Scan, VDC, engineering, and fabrication under one contract. No coordination chain between a survey firm, a drafter, and a fab shop. OnSite3D owns the full scope and owns the outcome.
Western Canada and US Gulf Coast
OnSite3D serves midstream operators out of Calgary, Grande Prairie, and Houston. Western Canada — including Northern Alberta pipeline corridors, SAGD facilities, and midstream gathering systems — is our anchor market. US Gulf Coast petrochemical and midstream rounds out our active footprint.
Our VDC and fabrication teams can ingest verified third-party scan data, which means the addressable scope extends beyond facilities we’ve scanned ourselves.
Tell Us Your Scope
Send us the facility, the tie-in, and the timeline. We’ll come back within 48 hours with a planning estimate — what we’d scan, how we’d coordinate it, and what we’d fabricate.
No commitment. No generic proposal. A real answer for your midstream project.
