eSign.AI Empowers China State Construction Hong Kong with a Smart, Compliant eSignature Ecosystem

Client Overview

China State Construction Engineering (Hong Kong) Limited (“CSCEHK”) has been engaged in the Hong Kong construction industry since 1979, covering a wide range of services including housing, civil engineering, foundation works, site investigation, E&M engineering, and concrete production.
Its parent company, China State Construction International Holdings Limited (“CSCI”), is a vertically integrated construction and investment enterprise listed on the Main Board of the Hong Kong Stock Exchange since 2005 (Stock Code: 03311).

Project Background & Challenges

Following the successful launch of the “Smart Construction Site” digital platform in 2023, CSCEHK initiated its Paperless Project in 2024.
The project aims to integrate OA systems, business platforms, and e-signature solutions to achieve full digital workflow automation—enhancing operational efficiency, compliance, and management quality through intelligent and lean management practices.

Why CSCI Chose eSign.AI

1. Independently Developed Global E-Signature Solution

For Chinese SOEs expanding overseas, local service providers with independent IP rights are a top priority.
eSign.AI, built under the “Local Presence, Global Service” philosophy, offers fully self-developed products with autonomous technology and long-term service assurance—making it the preferred partner for CSCI.

2. Hong Kong Local Authentication Integration

Given that most operations are based in Hong Kong, identity authenticity and intent validation are essential.
eSign.AI integrates with the Hong Kong government’s “iAM Smart” digital identity platform, enabling high-level local authentication that meets legal and compliance requirements.

Application Scenarios

Product Used

• eSign.AI International Platform

Document Types

• HR Department: Employee Employment Contracts
• Safety & Environmental Dept.: Subcontractor Compensation Notices
• On-site Projects: Labor Contracts for Subcontracted Workers

Business Challenge

The main HR system of CSCEHK is SAP HCM, while onboarding is managed via Beisen Recruitment System.
Although the business logic is similar to mainland operations, integration with standardized templates and signing APIs was essential for seamless digital signing.

Solution & Outcomes

Through SaaS API integration, eSign.AI connected seamlessly with the company’s self-developed “Happy Worker App”, enabling instant digital onboarding.

After completing profile details, workers can sign labor contracts via facial recognition and digital signature.
All signed documents are automatically archived in the group’s OA system, while workers can access or download them via the app.
This solution significantly improved onboarding efficiency, reduced paperwork, and strengthened data compliance—empowering CSCEHK’s digital transformation journey.
