Prior to an excavation, the ground should and must be assessed for unknown utilities or buried obstructions that could pose hazards to the work process. This is part of the due diligence that every permit writer or area owner should require from contractors or plant employees in order to issue a Safe Work Permit for the job site, thus allowing work to begin.

Proper GPR floor scanning helps prevent costly mistakes such as cutting through post-tension cables or damaging embedded utilities, which can lead to structural failures, safety hazards, and expensive repairs. By utilizing advanced scanning techniques and skilled interpretation, professionals can generate detailed subsurface images that guide engineers and contractors in making informed decisions.

To ensure accurate results, an Ultrasonic Pulse Velocity (UPV) instrument was used to assess the integrity of the grade beam due to the accessibility of both sides of the structure. Signal velocity readings were collected based on the given wall thickness information and the signal trace characteristics.

The objective was to assess the structural integrity and layout of the grade beams beneath the concrete slab to aid in potential redevelopment planning.

In a recent structural assessment project in Houston, Texas, OmniVueNDT employed advanced non-destructive testing (NDT) methodologies to evaluate the integrity of a concrete grade beam within a building. The primary objective was to identify and assess potential flaws or voids that might compromise the structural support of the beam.

With this approach, highly accurate measurements can be taken of the reinforcement layout, including rebar spacing, post-tension cable positioning, and references to permanent structures such as columns or drain grates. The integration of GPR and LiDAR ensures that every detail is preserved in a digital format, facilitating better collaboration and decision-making.

OmniVueNDT was engaged to provide engineering support in a renewable energy project to provide an accurate assessment of the drainage tile system of the farmlands. We utilized a custom built and engineered GPR land surveying system that is tough enough to withstand the extremely rough terrain conditions and the high wind gust on the field.

When a severe thunderstorm or a tropical cyclone hits an area, it typically leaves great damage behind. Buildings are usually flooded by the amount of rain that is the aftermath of storms. Flooding could leave structural issues in building foundations.

OmniVueNDT utilized different methods to locate underground utility lines starting with the Utility Locator, Fisher Metal detector and low frequency GPR (Ground Penetrating Radar).

OmniVueNDT was requested to perform a difficult task to locate and mark out the location of post tension cables and steel reinforcement on the celling of the restaurant for anchor bolt installations.

This project was performed in a two level parking garage in Clear Lake, Texas, and the actual scope of work was to locate rebar layout in order to design metal brackets. Those metal brackets would provide structural support to the cross beams and the concrete slab.

Scanning was performed on the 13th floor at the tallest parking garage of Houston, TX in the Medical Center. The scope of work was to produce rebar layout in a most accurate way prior to coring.

Company was contracted to perform a structure scanning service in real time mode to locate unseen reinforcement inside the concrete structures.

The company was contracted to perform a formal 3D structure scan on a subfloor to determine the layout of the radiant heating system inside the concrete slab for future construction.

GPR scan was performed on two areas next to each other to map out steel reinforcement system of a concrete slab on grade. High frequency GPR system with a GSSI SIR-4000 data collected was used to perform the scan and produce information for further use.

After the assessment was complete the GPR images were proving that the construction design is different from the as-built drawings.

BIM (Building Information Modelling) is an intelligent 3D model-based process that gives architecture, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.

A mobile crane collapsed while lifting, which occurred due to an unknown and unseen underground void. No GPR scan was ordered by plant engineering and craning and rigging department. Outrigger positions were not scanned either to make sure that the ground beneath the concrete pad is solid and firm enough to withstand the dead weight of the crane. A load bearing capacity investigation would also be recommended on crane pad locations prior to crane placement.
