3D Laser Scanning and As-Built Services

Reduce project risk, eliminate costly site errors, and accelerate engineering decisions with high-precision 3D laser scanning and intelligent as-built modelling services.

Alchris Energy provides advanced 3D laser scanning and as-built documentation services for oil and gas facilities across Nigeria. Using industry-leading laser scanning technology and intelligent modelling platforms, we capture existing facilities with millimetre accuracy to support engineering design, brownfield modifications, asset integrity programmes, revamps, and construction projects.

Our digital capture solutions provide engineering teams with reliable field data that enables safer designs, improved constructability, and better project execution

Why Existing Facility Data Matters

Many oil and gas facilities operate with outdated drawings, incomplete documentation, and undocumented modifications. This creates significant risks during engineering and construction activities, including:

Design clashes during installation
Incorrect dimensions and measurements
Construction delays
Increased rework costs
Safety risks during brownfield modifications
Procurement errors
Installation difficulties

Key Benefits of 3D Laser Scanning

Eliminate Design Clashes

Identify potential conflicts before fabrication or construction begins.

Reduce Rework Costs

Accurate field information minimizes costly site modifications and redesigns.

Improve Safety

Reduce site visits and minimize exposure to hazardous environments

Faster Project Execution

Engineering teams work with reliable data from the beginning of the project.

Better Brownfield Modifications

Integrate new facilities with existing infrastructure accurately.

Improve Construction Planning

Enable constructability reviews and virtual walkthroughs before mobilization.

Applications Across the Asset Lifecycle

Our laser scanning and as-built services support:

Engineering Design

Provide accurate field data for FEED, detailed engineering, and design development.

Design Verification

Validate existing conditions before commencing modifications.

Fabrication Verification
