At ACUO SI Ltd, we combine advanced Non-Destructive Testing (NDT) with cutting-edge reality capture to provide structural engineers, lead contractors, and consultants with clear, defensible data.

We deliver the "ground truth" of your site. By revealing hidden structural details and buried infrastructure, we empower you to de-risk projects, prevent utility strikes, and make critical engineering decisions with absolute certainty.

Our Core Capabilities

1. Concrete Scanning & Non-Destructive Testing (NDT)

We utilize a multi-technology approach to assess the internal health and structural integrity of built assets without causing damage.

• 3D Concrete Ferro Scanning: High-resolution mapping of reinforcement layouts, depth of cover, and bar diameters for safe pre-drilling clearance and structural capacity verification.

• Ultrasonic Pulse Velocity (UPV): Advanced structural void detection. We identify internal anomalies, honeycombing, and delamination that standard GPR methods often miss.

• Corrosion & Condition Assessments: Comprehensive half-cell potential mapping and structural monitoring to evaluate asset longevity and concrete degradation over time.

2. PAS 128 Utility Mapping & Subsurface Investigation

(H3 Header) We mitigate ground risk by providing highly accurate, fully compliant mapping of buried infrastructure.

• PAS 128 Compliant Surveys: Delivering recognized industry-standard utility mapping (QLD to QLA) to prevent costly utility strikes and ensure safe excavations.

• Subsurface Anomaly Detection: Locating hidden voids, historic foundations, and buried structures to inform safe, accurate site planning.

3. Digital Twin Reality Capture & Augmented Reality (AR)

We bridge the gap between the physical site and the digital office, delivering high-fidelity spatial data that supports BIM and "Golden Thread" compliance.

• Matterport LiDAR Surveys: Creating millimeter-accurate, immersive digital twins for exact as-built records and remote site management.

• Live On-Site AR Reporting: Pioneering the use of Augmented Reality to overlay hidden structural data directly onto the real-world environment, enabling real-time stakeholder visualization and rapid decision-making on site.
