Soil Contamination Survey "Green Test"

Soil Contamination Survey "Green Test"

We will diagnose the "land of concern" and give it our stamp of approval as "land that can be sold and lived on with peace of mind"!

At House Stage, we conduct a "Green Test" to assess the land. We carry out three assessments: "Ground Investigation" to understand the hardness and softness of the ground and any obstacles in the deep layers, "Subsurface Exploration" to check for underground obstacles, and "Soil Diagnosis" to determine the presence of soil contamination. Selling land with issues such as underground installations, weak ground, or soil contamination can lead to significant problems with business partners later on. By conducting a ground diagnosis, the risks hidden in the land become clear. Would you like to add unseen value and provide land with greater peace of mind? 【Implementation Details】 ■ Ground Investigation ■ Subsurface Exploration ■ Soil Diagnosis *For more details, please refer to the PDF document or feel free to contact us.

Infomart, Survey on Overtime Limit Regulations in the Construction Industry and the Status of Business Digitalization

Infomart, Survey on Overtime Limit Regulations in the Construction Industry and the Status of Business Digitalization

【News 2023/6/22】The construction industry's back office still strongly retains a paper culture.

◆ The most common method of document exchange is "paper" Infomart Co., Ltd. announced the results of a survey on "Overtime Limit Regulations and the Status of Digitalization in Business" targeting 362 employees in the construction industry on June 15. As a result, regarding the "Overtime Limit Regulations" starting in fiscal 2024, less than 10% of respondents said they "know about it and can explain it to others," while about half answered "I don't know." In terms of business digitalization, the most common method of document exchange was "paper" at about 30%, followed by "Excel or spreadsheets" at about 20%. Notably, the response that invoices are on paper accounted for about 40%, the highest among all documents. ◆ Over 60% manually transcribe invoices The most common method for transcribing various document data into the system was "transcribing from Excel or spreadsheets," followed by "manual transcription from paper," with over 60% manually transcribing invoices. About 30% of sales representatives reported spending more than three hours a day on "traveling for document exchanges," revealing wasted time caused by "paper." Construction IT journalist Ryuta Ieiri stated that by eliminating the three wastes of "wasted travel," "wasted effort," and "wasted time searching for items," construction DX can be further promoted.
