Construction Surveillance & Weld Quality Verification

Service Overview

Oil and gas construction operates under demanding safety imperatives governed by strict codes (ASME, API, AWS). Desapex augments traditional inspection with scan-based dimensional verification that provides objective, data-driven quality evidence.

Our Digital-First Approach

Scan at Milestones

Deploy laser scanning at critical milestones like foundation completion and steel erection

Analyze Deviations

Run automated deviation analysis comparing scan data against the design model.

Core Deliverables

  • 3D constructability reviews identifying heavy lift sequences and access constraints.

  • Dimensional verification of equipment foundations and anchor bolt patterns before setting.

  • Safety management integrating BIM-based hazards with simultaneous operations (SIMOPS) coordination.

  • Avoidance of equipment re-setting incidents that can cost $200,000+ per occurrence.

Why Choose Desapex

Discovering a misaligned equipment foundation after a heavy lift is incredibly expensive. Our pre-setting scan verification catches dimensional errors early, when correction is simple and inexpensive

Unique Selling Proposition

Our USP is the creation of a permanent, timestamped, millimeter-accurate construction quality record that lives in the project’s digital twin, serving regulatory inspections and future modification engineering for the life of the facility.
