For CapEx Project Managers
Reduce Execution Risk Before Construction Begins
Most brownfield capital project risk doesn’t emerge during construction — it was embedded at the planning stage, when existing conditions were assumed rather than verified. By the time the spool doesn’t fit, the drawing was wrong six months ago.
OnSite3D helps capital project teams close that gap. Laser scanning establishes verified existing conditions before engineering begins. VDC coordination catches clashes and deviations before fabrication. And fabrication from verified scan data delivers spools that fit the first time — on a schedule you can defend.
Field Rework Is a Planning Problem, Not a Field Problem
Non-fitup events, installation delays, and TA extensions are almost always traceable to the same root cause: the design didn’t accurately reflect existing conditions. The field crew didn’t create that problem — they inherited it.
For capital project managers, that means the critical path is exposed to risk that was locked in before a single piece of steel was cut. Every “field verify” stamp on a fabrication drawing is a deferred risk that lands on your schedule.
OnSite3D eliminates that risk by verifying conditions at the source — before engineering, before fabrication, before the outage window opens.
From Verified Conditions to Installed Deliverable
Existing Conditions Capture
High-accuracy 3D laser scanning of the facility before engineering begins. Point cloud registered, hosted on WebShare, and available to your engineering team as the verified design basis. No “field verify” assumptions in the fabrication package.
Constructability & Clash Review
Our VDC team coordinates the point cloud against the design model — identifying clashes, deviations, and constructability concerns before anything is fabricated. This is where brownfield surprises get resolved at desk cost, not field cost.
Scan-to-Fabrication
Fabrication packages built from verified scan data. ABSA AQP certified weld procedures. Laser QA on every spool. 94%+ in-tolerance documented. On the Acid Gas Injection Upgrade, OnSite3D achieved 98% off-site prefabrication — because the conditions were known before fabrication started.
TA Integration & Post-Project As-Built
OnSite3D integrates into your TA execution plan: virtual assemblies validate fit-up before the outage window, in-TA dimensional support resolves tie-in issues in real time, and post-TA as-built captures the permanent record for the next capital cycle.

What OS3D Delivers on a Capital Project
3D Laser Scanning
Verified existing conditions before engineering begins — eliminates field verify assumptions.
VDC Coordination
Clash detection, deviation reporting, constructability review — at desk cost, not field cost.
Brownfield Engineering & MRO
CWPs and tie-in packages from verified scan data — ABSA AQP stamp.
Scan-to-Fabrication
Spools fabricated to verified tolerances — first-time fit-up by design.
Virtual Assemblies & 4D Simulation
Digital fit-up and sequencing validation before the outage window opens.
Turnaround & STO Support
In-TA dimensional support, real-time tie-in coordination, post-TA as-built.
One Partner Accountable for the Whole Workflow
Schedule Certainty
Verified conditions before fabrication means the critical path doesn’t carry a hidden non-fitup risk. First-time fit-up is the designed outcome — not the plan if everything goes right.
Single Point of Accountability
Scan, VDC, engineering, and fabrication are one integrated workflow at OnSite3D. No handoff chain between separate vendors. When something needs to change, there’s one phone number.
Documented Quality at the Weld Level
ABSA AQP certified. Laser QA on every spool. 94.36% in-tolerance documented on CN-1001. Quality isn’t a general compliance claim — it’s a weld-level record that follows the deliverable.
Long-Term Capital Planning Value
The as-built OnSite3D delivers doesn’t just close the current project — it becomes the verified baseline for the next modification, the next TA, and the next capital cycle. The data compounds across project phases.
