According to the 2013 Report Card published by the American Society of Civil Engineers (ASCE), one in nine bridges in the United States is structurally deficient. Tight budgets require efficiencies when selecting work to be done and so priority is often given to those tasks that will make these structures last as long as possible. […]

OSHA has proposed new standards for respirable crystalline silica exposure and a new uniform airborne permissible exposure limit (PEL), calculated as an eight-hour time-weighted average. The agency has identified 25 industry subsectors encompassing approximately 130 industrial and maritime operations in which exposure to respirable crystalline silica is common during operations such as cutting and grinding […]

Failure Analysis Determines Faulty Workmanship, Not Defective Building Materials, Caused Damage

Post by:

Defining the Challenge Upon completion of a high-rise residential structure, cracks and delamination appeared on exterior surfaces of the tower compelling building owners to initiate a lawsuit against the general contractor. The contractor, in turn, blamed faulty materials used by subcontractors. With so many subcontractors involved in this large construction project, it seemed an almost […]

Enterprise-Wide Data Integration Solution

Post by:

Where They Were Leaders in the U.S. Air Force needed to be able to access the entirety of the health conditions of each of their weapon systems. The problem was that the required data was scattered among isolated systems each holding only a fraction of the information needed. Leaders identified the following needs: Assess readiness […]

Collected Intelligence Promotes Safety and Readiness

Post by:

Automate, Consolidate, Forecast The U.S. Air Force fleet team for jet engine propulsion systems was charged with improving the safety and operational use of jet engines. During that process, they were able to generate fleet data from engine sensors, maintenance systems and original equipment manufacturer (OEM) models from numerous airbases. However, they did not have […]

Extending the Safe, Healthy Life of Jet Engines While Improving the Readiness and Availability of the Fleet

Post by:

Personnel safety is of prime importance to all our armed services and so the aircraft that the U.S. Air Force flies must be in A-1 condition at all times. The complex systems and sub-systems of a jet engine require individual attention including varying degrees of maintenance required to remain in top condition. And so, decision […]

Capacitor Testing Provides Data for Possible Patent Infringement

Post by:

RJ Lee Group received several de-mounted multi-layer ceramic SMT capacitors for examination. The devices were involved in a possible patent infringement case dealing with device design and the electrical properties of the insulator material. Three of the devices were selected for a survey by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analysis. The […]

Did a Cracked Pipe Cause a Landslide?

Post by:

A landslide that released fly ash materials into a drainage stream causing environmental concern was attributed to a failed municipal water pipe. The section of pipe that was removed had been examined by others and specimens had been cut from it during the previous examinations. Once we were afforded access to these specimens, we performed […]
