Open House Architect Implements 'Techtouch AI Hub' into Field Management Platform 'Optimus'

Techtouch Inc. announced the implementation of its 'Techtouch AI Hub' into 'Optimus,' a field management platform used by Open House Architect, a firm with an annual building record of approximately 5,000 units and a cumulative total of approximately 56,000 units. Instead of replacing entire workflows with AI, the company adopted an approach of 'incorporating' only the necessary functions at points where AI is truly effective. AI capabilities were implemented using a no-code method in as little as 30 minutes, realizing efficiency and quality improvements in cost management, internal applications, and quote request workflows.

■ Background of Implementation
Open House Architect promotes DX through in-house technology development under the mission, 'Innovation in Architecture.' Their core field management platform, 'Optimus,' was developed to address entrenched issues in the construction industry such as paper-based processes, high dependency on human expertise, and labor shortages. Through digitization of ordering, receiving, and billing via a unique EDI feature, the speed, accuracy, and transparency of their operations have steadily improved.

However, as AI utilization advanced, new challenges emerged. Construction workflows are a mix of areas where AI excels (information aggregation, summarization, text generation) and areas where human judgment and experience are indispensable (field response, final approval). Therefore, an approach that replaces the entire workflow with AI raised concerns about potential confusion and quality degradation. Furthermore, using AI as a separate tool created an additional burden for field workers, and the presence of non-digitized and siloed data made enterprise-wide AI utilization difficult.

■ Key Decision Factors
Given these realities, the company chose a 'targeted add-on' approach, applying AI functions only where they are most effective within existing workflows. This enables the optimal allocation of tasks between AI and humans, natural AI utilization with zero learning cost for the field, and rapid, stage-based scaling. This was a strategic decision embodying the company’s DX policy: 'Speed x Field-Focus x Cost-Performance.'

'Techtouch AI Hub' was selected as the foundation for this approach. The company has been using the 'Techtouch' Digital Adoption Platform (DAP) within 'Optimus' for three years. The decisive factors were the ability to integrate generative AI without code as an extension, the capability to add AI features without changing the existing UI/UX, and confirmation of smooth deployment during the trial phase.

■ Main Use Cases and Future Outlook
Operations began in three key areas: 1. Summarization of cost status, 2. Pre-submission checks for internal applications, and 3. Support for creating quote request text. Frontline workers have commented that it is highly useful for new employees and those unfamiliar with the system, functioning according to the company’s vision of a 'workline design where the field receives the benefits of AI without conscious effort.'

Moving forward, the company aims for more active AI implementation as an 'accelerator' for system evolution, while continuing concrete process improvements such as shortening approval times through advanced cost risk detection and enhanced application checking functions.
