Proposal for Piping Inspection

Proposal for Piping Inspection

Would you like to have a health check for your pipes? It's essential to first investigate the current condition of the pipes for issues like clogs and corrosion!

Circulating within the building, the plumbing for water supply and drainage can be likened to "blood vessels" in a person. Just as human blood vessels and building plumbing age (deteriorate over time), they can develop various troubles. To continue using the "plumbing," which is also the blood vessels of the building, it is important to conduct regular health check-ups to prevent troubles before they occur. Additionally, maintenance and inspection of the exterior drainage are also important. Our company offers solutions from high-pressure cleaning to resolve blockages in drainage pits and pipes, as well as repair work for cracks. 【Investigation Methods and Points for Selecting Investigation Locations】 ■ Ultrasonic thickness measurement: Calculate remaining lifespan ■ Endoscopic inspection: Check the condition inside the pipes ■ X-ray investigation: Check the condition inside the pipes ■ Pipe removal inspection: Calculate remaining lifespan *For more details, please refer to the PDF document or feel free to contact us.

Proposal for Non-Destructive Testing

Proposal for Non-Destructive Testing

No need to worry about water outages or drainage restrictions! Ultrasonic thickness measurement, X-ray inspection, and endoscopic examination are effective.

In conventional deterioration surveys, the only method that allowed for estimating remaining life through thickness measurements and understanding corrosion conditions was destructive testing, specifically pipe removal inspection. However, pipe removal inspection has many limitations, such as water shutdowns, drainage regulations, and nighttime work restrictions. Our company offers a high-precision deterioration survey that combines various diagnostic methods to conduct non-destructive testing similar to pipe removal. Please feel free to contact us when needed. 【Features】 ■ By identifying areas of wall thinning through X-ray inspection, pinpoint thickness measurements are possible. ■ Thickness measurements are conducted after assessing the condition of the piping, making it easier to detect pitting corrosion. ■ High-precision survey data can be provided. ■ No restrictions on working hours (nighttime). ■ There are no water shutdowns or drainage regulations, allowing for uninterrupted use of equipment and reducing the risk of leaks. *For more details, please refer to the PDF document or feel free to contact us.

Are the buildings okay after the earthquake? Early inspection of the exterior walls is important. Saitama, Tokyo.

Are the buildings okay after the earthquake? Early inspection of the exterior walls is important. Saitama, Tokyo.

We can perform everything from inspection to repair without scaffolding.

When an earthquake occurs, many people first worry about the collapse of the building itself or damage inside. However, what should be noted in building management is the "external damage" such as exterior wall tiles, mortar, sealing, and exterior materials. Even if there is no significant damage to the entire building, the shaking from the earthquake can gradually put stress on the exterior walls. Particularly in existing buildings, areas where the adhesive strength has already decreased due to aging or where fine cracks have developed may progress to detachment or peeling as a result of the earthquake. The Ministry of Land, Infrastructure, Transport and Tourism also emphasizes the importance of maintaining a state without damage that poses a risk of falling, by checking for "cracks, defects, and detachment" on the exterior walls. Even if there seems to be no problem on the surface, the adhesion between the tiles or mortar and the substrate may have been compromised internally. Using rope access, we can conduct high-altitude exterior wall inspections without setting up scaffolding. We also respond to inspections of specific areas of concern, tapping surveys, and emergency repairs. A "precautionary check" after an earthquake can prevent major accidents before they happen. For exterior wall inspections and repairs in Tokyo, Chiba, Saitama, and Kanagawa, please consult TRAWE.

We will conduct an investigation into the circumstances of employees (executives) who resigned under unsettling circumstances. This is the most suitable investigation menu for confirming violations of the Unfair Competition Prevention Act and other issues.

Investigation of Trends of Departing Employees and Related Employees In companies, there is a risk that departing employees may move to competing companies and improperly utilize important information such as trade secrets, customer information, and technical information. Such actions may fall under the illegal acquisition, use, or disclosure of trade secrets as defined by the Unfair Competition Prevention Act, or violations of non-competition obligations. Our company conducts trend investigations using lawful investigative methods regarding the new employment of targeted employees, their involvement in business, and their contact with clients, organizing facts related to the existence of competitive relationships and suspicions of trade secret utilization as objective materials. The investigation results will be compiled into a report that includes behavioral records and chronological organization, and will be provided as evidence collection investigations that can be utilized as proof in legal examinations by lawyers, including injunction requests, claims for damages, and applications for provisional disposition. This is a risk management investigation that contributes to the protection of corporate trade secrets and the maintenance of compliance systems.

Accessory Screening Survey (Corrosion Doctor)

Accessory Screening Survey (Corrosion Doctor)

Screening investigation and corrosion site identification using non-destructive testing technology.

Steel columns such as signposts and lighting poles along the road are most susceptible to corrosion at the boundary with the road surface (ground level), and as damage progresses, there is a risk of collapse. In the accessory screening survey, an ultrasonic diagnostic device called "Corrosion Doctor" is used to diagnose the corrosion condition at the ground level (around GL−40mm) on-site without excavating the road surface. Compared to conventional inspection methods (close visual inspection, trial excavation, residual plate thickness measurement, and restoration), this method not only reduces inspection costs but also eliminates the need for road traffic restrictions, significantly improving work efficiency and safety. Results can be immediately classified into three categories: "sound," "almost sound," and "corrosion present," making it ideal for narrowing down columns that require detailed investigation. Furthermore, this device is registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS (KT-150121-VE) and has been selected as a technology for promotion and utilization.

Salt damage investigation (salt analysis and corrosion survey for concrete and steel structures)

Salt damage investigation (salt analysis and corrosion survey for concrete and steel structures)

Visualize the salt content and accurately grasp the deterioration progress of structures that can be utilized in longevity planning.

Salt damage investigation is a survey conducted to evaluate whether concrete structures and steel materials are deteriorating due to the effects of salts contained in sea salt and de-icing agents. It is carried out on various structures, primarily focusing on social infrastructure such as bridges, buildings, port structures, and road structures. Our company conducts sample collection using the drill method or core method and quantitatively assesses the penetration of salts by analyzing the amount of chloride ions at different depths. Furthermore, by combining this with rebar detection using electromagnetic radar methods, we can correlate the positions of rebar with the amount of salt, allowing for a more detailed assessment of the progression of salt damage. Additionally, by conducting natural potential measurements and rebar exposure surveys, we can confirm the presence of rebar corrosion and the areas that require repair, providing valuable data for the consideration of maintenance and repair plans.

Supporting reliable structural design! Providing appropriate design input seismic motions based on site conditions.

To create design input seismic motions that take into account the characteristics of "long-period pulses" and "long-period, long-duration seismic motions," it is very important to evaluate the source, propagation path, and ground amplification characteristics. By applying new seismic motion predictions, our company, which specializes in ground surveys, will conduct ground modeling and response analysis to provide appropriate design input seismic motions based on the site conditions of the planned building. Please feel free to contact us when needed. 【Main Content】 ■ Boring surveys, PS logging, continuous microtremor analysis, etc. ■ Evaluation of seismic motions based on past damaging earthquakes and simplified methods, etc. ■ Semi-empirical methods, theoretical methods, hybrid methods, etc. ■ Equivalent linear analysis, sequential nonlinear analysis, etc. *For more details, please refer to the PDF materials or feel free to contact us.
