Requirement analysis:

① The queue for stamping at the headquarters is severe - there are many physical seals.
Daily stamping must be printed in paper documents and brought to the group headquarters for stamping. The frequent queuing of stamping personnel in front of the office and the low efficiency of stamping in person have affected the normal operation of the company. ② High cost of stamping in different locations offline - It is difficult for remote stamping by branch offices in different locations. When branch offices, project departments, etc. need to stamp, they must return to the headquarters for stamping, which not only wastes a lot of taxi and mailing fees during the round trip; Going back and forth between the two places, queuing up at the headquarters for stamping, and other situations will consume a lot of labor and time costs.
③ Paper documents are prone to tampering - there is a high demand for daily signatures
Daily stamped documents need to be printed and stamped after approval by leaders, which may pose a risk of tampering with the approved documents, which is difficult for manual detection. By using electronic signatures to digitize the entire process of document approval and signing, the entire process of document tampering prevention is more secure. ④ Digital transformation of the entire business process - long offline signing and stamping cycle, high cost. The group has deployed management software covering multiple dimensions such as office and operation, and has a mature digital management foundation. Introducing electronic signatures to promote online signature and stamping of business documents has become the last mile of the digital transformation of Shanxi Construction Engineering's entire business process.
Application scenario:

electronic signature
with multiple software sets to expand the electronic signature function of business systems, build business electronic signature scenarios as needed, and assist in the full digital transformation of business approval, signing, and archiving

This time, Shanxi Construction Engineering Group completed multiple software applications such as the existing engineering project system, construction system, OA system, invoicing business system, examination and training system, as well as the integration and docking of WeChat official account and contract lock, embedded the application of electronic signature and seal in more than 30 business processes, realized the electronic signature and seal of business documents, made personnel, procurement, subcontracting, document issuance, leasing and other business contracts digital throughout, and helped reduce business costs and improve efficiency. Scenario 1: Issuing official documents and approving daily stamping processes in the OA system. Using Panwei OA as the operating platform, the main users support internal document issuance and daily stamping approval and stamping within the group. Each department only needs to initiate one OA process for official document issuance and internal stamping, which can be approved and stamped online, saving the trouble of printing, communication between departments, queuing, etc., and improving stamping efficiency. Business personnel log in to the OA system, fill in the seal information, and initiate seal approval. After approval by the leader, the contract lock interface will be automatically called to generate electronic files and sign the process. The OA system generates a stamping task during the signing process, and the signer can manually drag and drop the contract lock electronic signature page to complete the stamping in the OA process. After signing, the stamped document will be automatically returned to the OA system for archiving and storage, and can be accessed and downloaded at any time.

Scenario II: Internal and external double signing and supplier certification scenario
For the scenario where double signing with suppliers is required in the signing scenario of engineering business, the contract lock integrates the existing engineering project system and construction system of Shanxi Construction Engineering Group, connects to the WeChat official account of Shanxi Construction Engineering Group, and provides identity authentication and mobile signing services for suppliers. Realize paperless signing of supporting contract documents such as labor subcontracting contracts, procurement contracts, and leasing contracts throughout the process. Business personnel log in to the business system, retrieve business information, upload business files, and initiate the signing process.
· After approval by the superior, the PDF file conversion will be automatically completed through the
Contract Lock
interface, and an electronic file and signing process will be generated.
· Internal personnel call the electronic signature page in the process to complete sealing. The system automatically sends a text message notification to the supplier, and by opening your phone, you can move and sign the document.

· All suppliers complete information registration, identity authentication, and maintain signature and seal information through Shanxi Construction Group in advance. There is no need for secondary authentication when signing, and signatures and seals can be called as needed to complete the signing. Scenario 3: Signing of Labor Service Contracts for Employees of Shanxi Construction Engineering Group Branch. In response to the signing of labor service contracts for employees of Shanxi Construction Engineering Group Branch, the contract lock is integrated with the new Zhongda D6C construction management system, providing electronic labor contract signing for both parties





Service, achieving batch issuance by HR, mobile signing of employees through SMS, and full digitalization throughout the process. Currently, this scenario is being deployed and is expected to be promoted for use this year. Scenario 4: Physical Seal Scene of Shanxi Construction Engineering Group. In response to the physical seal scene that still exists within Shanxi Construction Engineering Group, the contract lock is connected to the OA and engineering business system as well as the seal control device. The physical seal is locked in the seal control device, and through online approval and authorization of the seal code, the seal user can unlock the device and securely and efficiently stamp it while taking photos and monitoring. By using electronic approval processes, the hassle of offline queuing for approval and stamping can be eliminated, helping to build a secure, compliant, and transparent physical stamping environment.
