Chengda Engineering Accelerates Cross-Border Procurement Signing

Company Introduction

China Chengda Engineering Co., Ltd. is a subsidiary of China National Chemical Engineering Group. Its predecessor was established in 1958, and the company is headquartered in Chengdu, China.

Chengda Engineering provides international engineering services across petrochemicals, natural gas chemicals, coal chemicals, fine chemicals, industrial power, pharmaceuticals, new energy, new materials, construction, municipal engineering, and environmental protection. Its projects span markets including the United States, Saudi Arabia, Brazil, Indonesia, Vietnam, Bangladesh, Pakistan, and Uzbekistan.

Business Challenges

In international engineering projects, procurement contracts often involve suppliers, project teams, procurement leaders, seal administrators, and overseas partners. The traditional paper-based workflow created several bottlenecks:

• Procurement contracts could take one week or longer to complete even in routine scenarios.
• Cross-border contracts sometimes required one to two months of circulation.
• Paper contracts and physical seals were difficult to trace once documents entered multiple internal and external handoff points.
• Compliance teams needed more complete evidence, audit records, and seal-use control.

For large engineering projects, delayed procurement signing can affect supplier collaboration, project execution, and commercial risk control.

Solution & Results

Chengda Engineering introduced an integrated electronic signing and seal management platform. After a contract is finalized, business users upload the electronic contract, fill in signer information, and initiate the signing flow. Suppliers sign online, procurement leaders review the document, and electronic seal administrators approve seal use before automatic stamping.

The solution supports digital seal permissions, evidence preservation, signing certificates, and audit logs. It also supports local dedicated cloud deployment, local file storage, hash extraction, and API expansion for future business-system integration.

Through this workflow, Chengda Engineering connected procurement signing, seal control, supplier execution, and archive management in a more traceable process.

Application Impact

Chengda Engineering increased signing efficiency by 80%, reduced the procurement contract cycle from one week to one day, and cut contract management costs by 50%.

The digital signing workflow strengthens procurement collaboration across regions while improving contract traceability, evidence retention, and seal-use governance for international engineering projects.
