Based on the location information obtained from GPS, it provides the operator with real-time data on the number of passes and planar position of the vibratory roller in the construction area, while automatically recording the construction history. This ensures reliable construction management and labor-saving compared to traditional manual methods or pass counters. ***Features*** - By managing the number of passes, it allows for a comprehensive management of the entire embankment surface, leading to improved quality. - The mesh size for management can be changed as needed (the standard specification by the Ministry of Land, Infrastructure, Transport and Tourism is 50 centimeters). The number of compaction passes is determined, and that specified number is executed. Different colors are displayed for each number of passes, allowing for immediate understanding of the compaction status and enabling a swift transition to the next layer of embankment, thus shortening the construction process. - By managing the number of compaction passes, it prevents over- or under-compaction. The operator can understand the number of passes through the color displayed on the onboard computer monitor, which helps prevent over- or under-compaction.

This is a system for real-time monitoring of tide levels by wirelessly transmitting tide level data measured at a measurement station to confirmation locations such as workboats and offices using a wireless modem. A measurement box and a wireless modem for transmission are installed at the measurement location, and power is supplied. At the location where data needs to be confirmed, a computer and a wireless modem for reception are set up, and once configured, measurements can be taken. Depending on the required variability and accuracy, an optimal configuration based on four types of sensors can be selected. ***Applications*** - Measurement of tide levels during marine construction and water-based projects, such as dredging and seabed improvement. - Management and monitoring of water levels in dams, ponds, and reservoirs, as well as in rivers and lakes. - Monitoring and verification of groundwater levels, such as well water and underground water. - Alarm systems for flood conditions in rivers. - Various other applications for measuring the depth of liquids.

Traditionally, it was difficult to measure weather data in locations without power facilities, but now it has become possible to observe this data by combining batteries and solar panels for power supply. The observation data is collected nationwide by utilizing NTT Docomo's FOMA communication network. If there is an environment where the internet can be accessed, real-time evaluation of the observation data can be done using a computer or mobile phone. Weather data can simultaneously observe six parameters: wind direction, wind speed, precipitation, atmospheric pressure, temperature, and humidity.

***Summary*** Concrete strength is generally measured by the compressive strength 28 days after pouring. However, if it is deemed insufficient at that point, rework is practically impossible. Against this backdrop, there is a demand for measurement equipment that can quickly determine the water-cement ratio of fresh concrete (mortar) on-site. Typically, the amount of cement in the water-cement ratio can be accurately understood from weighing records, but the water content is difficult to ascertain accurately due to the inclusion of surface water adhering to aggregates and the need to consider adjustments for slump compatibility. If moisture measurements of fresh concrete (mortar) are conducted at the time of construction, and the unit water amount is determined accurately, it would be possible to avoid such troubles.
