【Industry First】70% Reduction in Estimation Workload. CORDER, Supporting 200 General Contractors, Launches AI Service 'Online Estimation Department' and Reveals Adoption Track Record

## About the Industry-First AI Service 'Online Estimation Department'

CORDER (Headquarters: Shibuya-ku, Tokyo; CEO: Kento Tanabe; hereinafter "CORDER") announces the release and adoption track record of "Online Estimation Department," the industry's first AI service specialized in the "estimation" field that directly impacts the profitability of the construction industry.

The service has already been adopted by more than 30 general contractors nationwide (including branches), significantly reducing the workload for estimation departments struggling with an aging workforce and labor shortages, and creating time for the critical tasks they should be focusing on.

## Background: The Crisis of 'Operational Dilemma' and 'Profit Decline' in Estimation Departments

While estimation work is directly linked to construction project profits, estimation departments face a serious dilemma.

The original role of an estimation staff member should be to focus on "important tasks necessary to increase estimation accuracy," such as quantity checks, quotation scrutiny, and analysis. However, they currently spend much of their time on simple "tasks" that do not directly contribute to estimation accuracy, such as requesting vendor quotes, creating comparison tables, and price entry. In fact, these tasks consume 70% of the entire estimation workload.

Furthermore, estimation departments in general contractors are facing severe aging, with "2 out of 3 people being over 50." Failure to reform these operations could lead to reduced profits due to lower estimation accuracy and lost opportunities due to excessive workload.

## Overview of 'Online Estimation Department'

"Online Estimation Department" is an AI service that provides hybrid support from AI and skilled estimators for the entire estimation process, from quantity takeoffs to price entry.

It also provides an environment to centrally manage project information, quotation status, estimation data, and correspondence history on the cloud. This allows for significantly streamlining daily operations while accumulating data as valuable knowledge.

## Benefits of Adoption

- Overwhelming Reduction in Workload: Significantly reduces the hours spent on "tasks" such as quote acquisition, comparison, and price entry, which previously accounted for 70% of estimation work.
- Creation of Time for Core Tasks: Realizes an environment where staff can focus on "original core tasks" that directly lead to quantity accuracy and cost optimization, such as quantity checks and quotation scrutiny.

## Rapid Adoption by Leading General Contractors

This service has garnered significant attention immediately after its release and is currently used by general contractors nationwide, including major firms such as Haseko Corporation, Maeda Corporation, Ando Hazama Corporation, and Tekken Corporation.

Additionally, over 4,500 partner companies are registered on the platform as business partners of these general contractors.

## Future Outlook: Expansion of Further Automation through AI

"Online Estimation Department" plans to sequentially expand AI features that maximize cost-reduction effects for customers, starting with the automation of price entry tasks.
