External wall sounding survey using rope access technology.

External wall sounding survey using rope access technology.

No scaffolding is required, so only inspections can be conducted! A method suitable for preventive maintenance of buildings.

We would like to introduce the exterior wall inspection survey using rope access technology. Since there is no need for temporary scaffolding, costs associated with scaffolding can be reduced. Repairs can also be carried out after the exterior wall inspection without the need for scaffolding. Additionally, with a flexible repair plan, the financial burden can be divided. Initially, only the severely damaged "sealing work" can be done, followed by "tile work" in the next term, and then "painting work," allowing for cost division. 【Features】 ■ Capable of conducting inspections on walls of buildings in narrow spaces ■ Suitable method for preventive maintenance of buildings ■ Inspections can be conducted without the need for scaffolding ■ Ideal for high-rise buildings, etc. *For more details, please download the PDF or feel free to contact us.

Preliminary survey

Preliminary survey

Measure the width, length, size, and depth of cracks, defects, and spalling using a crack scale!

The tapping survey is a method of investigation where specialized tools (tapping rods, tapping hammers) are used to strike walls and assess their condition based on the sound produced. Investigators work using both visual inspection and the pitch of the sound, and tactile examination is conducted simultaneously, allowing for a very accurate assessment of the external wall's condition. The accuracy of the survey is influenced by the skill of the investigator, which is why our company provides training to rope access engineers aimed at standardizing skills and further improving their expertise, thereby enhancing the uniformity of inspections. 【Features】 ■ Assessing the condition by striking the wall with specialized tools (tapping rods, tapping hammers) and analyzing the sound ■ Investigators work using both visual inspection and sound pitch ■ Tactile examination is conducted simultaneously, allowing for a very accurate assessment of the external wall's condition ■ Measuring the extent of detachment, crack width and length using a crack scale, and assessing the size and depth of defects and spalling *For more details, please download the PDF or feel free to contact us.

Non-scaffolding method for exterior wall inspection that eliminates the need for scaffolding, enabling cost reduction and shortening of construction period.

No scaffolding is required, so inspections can be conducted alone! A suitable method for preventive maintenance of buildings! The need for scaffolding installation and dismantling is eliminated, allowing for cost reduction and shortened construction periods.

BCS Survey (Beyond-CS Survey / Customer Reconnection Survey)

BCS Survey (Beyond-CS Survey / Customer Reconnection Survey)

Is customer satisfaction research insufficient? A new approach to addressing churned and dormant customers.

"Why did customers who were supposed to be satisfied leave?" The answer may lie among those who "said nothing." The "silent type of churn" refers to those who leave without expressing dissatisfaction. The BCS survey (Beyond-CS Survey) visualizes the "reasons for churn" that traditional customer satisfaction surveys could not capture. It is a new research approach that collects the voices of dormant and churned customers to lead to improvements and reconnections.
