Mechanical Room 3D Documentation Houston, TX

Houston, TX

Project Overview

OmniVueNDT conducted a high-resolution 3D laser scanning survey in a mechanical room in Houston, TX, to support Building Information Modeling (BIM) workflows. This documentation process provided accurate spatial data for use in design, construction and facility management applications.

BIM is a model-based approach that allows architecture, engineering and construction (AEC) professionals to efficiently plan, design, construct and manage buildings and infrastructure. The integration of 3D laser scanning into the BIM process ensures precise as-built documentation for engineering analysis and project coordination.

Target Placement & Data Acquisition

The laser scanning process began with the strategic placement of registration targets (See Picture 2) on permanent stationary objects. These targets serve as linking points to align individual scans into a cohesive PointCloud model during post-processing.

Types of Registration Targets:

• Checkerboard Targets (See Picture 4) - High-contrast flat targets that assist with scan alignment.

• Spherical Targets (See Picture 5) - 3D markers that improve registration accuracy across different perspectives (See Picture 3).

Targets were systematically placed throughout the mechanical room (See Picture 6) and scans were performed with optimized laser grid density settings (1.5M points within a 10m range).

Data Processing & Registration

Following data acquisition, all scan positions were compiled and point cloud registration was performed.

• Scan Station Locations - Identified on a plain view map (See Picture 7) to track individual scan placements.

• Alignment Accuracy - Achieved a registration tolerance of less than 1/4” within a 10m range, ensuring high-precision data alignment.

• Data Filtering & Refinement - Applied to enhance clarity and remove unwanted noise.

Upon successful registration, the PointCloud dataset was ready for further analysis or vectorization, supporting integration into CAD, BIM or other engineering applications (See Pictures 8 and 9).

Key Benefits of 3D Documentation

• Accurate As-Built Representation - Ensures precise spatial documentation for design modifications.

• Measurable Objects & Distances - Enables engineers to extract exact dimensions without site visits.

• Enhanced Project Coordination - Supports seamless collaboration between design, construction and operations teams.
