Requirement analysis:

Due to various difficulties faced by offline stamping of paper materials, such as "easy forgery and denial of documents and materials", "difficult identification of the real identity of the signatory", and "difficult management of engineering archives", offline stamping can no longer meet the requirements of refined project management. ① Difficulty in identifying the real identity of the signatory: The investment amount of Kala Hydropower Station is large, the construction period is long, there are many participants (owners, designers, supervisors, various construction units, third-party units, etc.), and information communication is frequent. It is necessary to ensure the real identity of each signatory and the reliability of data. ② Difficulty in anti-counterfeit of engineering project documents: The daily business volume of hydropower projects is huge, and various contracts are frequently used, such as "quality inspection and evaluation, construction orders, engineering drawings, contract opinion approval, engineering archives, etc." Hundreds or thousands of pages of documents need to be stamped, and paper documents are easy to forge, making anti-counterfeit and traceability difficult. ③ Sign completion documents to prevent repudiation: Various business entities, including the construction and participating companies of the Kara hydropower station, have to sign a large number of engineering documents every day. The offline signing process is difficult to trace, and important engineering data lacks key evidence, making it easy to deny. It is also difficult to identify responsible parties when problems arise.
④ Pilot requirements for digital archives: As the first pilot unit of a central enterprise to pass the acceptance of digital archives, Huadong Institute needs deeper application of digital archives. The digitization of engineering data through electronic signatures is an important attempt in the digital archive management practice of East China Institute.
Application scenario:
This time, the contract lock is integrated and connected to the engineering management system and archive system independently developed by East China Institute. Through system linkage, the integration of engineering data approval, signing, and archiving is achieved. Assist in expanding the electronic signature function of the engineering management system, achieving unified signing message, unified pending, and unified signing process, allowing hydropower project participants to initiate signing, approve signing information, sign engineering documents, check signing messages, and query signed documents on the engineering management system platform, realizing automatic synchronization of signed materials to the archive system for archiving and easy access at any time, comprehensively improving the efficiency of signing cooperation among project participants, and helping to reduce project costs and improve efficiency.
Scenario 1: Electronic signature of "Engineering Inspection and Evaluation Form"
The signing process of hydropower station engineering inspection and evaluation involves multiple signatories, and the approval process requires the construction and supervision parties to add comments on the contract (embedding the process approval comments into the contract for display); Finally, both parties must affix their seals before it can take effect. The contract lock integrated engineering management system provides approval comments and annotations for the signing of inspection and evaluation forms, as well as electronic seal functions for both parties, flexibly meeting the signing scenarios of inspection and evaluation forms at East China Institute.
Detailed scenario description:

① Construction unit business personnel submit applications, call the contract lock creation and initiation interface, generate pending documents, and specify the form field range. After the contract is initiated, the contract lock form field function is called at each approval node to embed the process approval opinions into the contract for presentation.





③ In the signing process, both parties' stamping personnel verify the signing intention and call the contract lock interface to complete the stamping. ④ Signed documents are returned to the business system for archiving.
Scenario 2: Electronic signature of "Construction Plan"
Detailed scenario description:
① Business personnel of the construction party log in to the engineering management system to submit the approval process. After approval by the contractor and the supervision unit, they can call the contract lock interface to create electronic files and sign the process. ② The contractor and supervisor's stamping personnel can check the signing messages and pending tasks online in the business system portal, verify their identity online, and call the electronic signature page to complete the document stamping. After the signing is completed, the engineering management system of East China Institute can preview or download the stamped contract documents online through the contract lock file download and query interface.
Scenario 3: Electronic signature of "engineering drawings"
Detailed scenario description:
① Design institute designers log in to the engineering management system to upload drawing files and initiate the review process. After the approval of the design institute leader, construction unit, owner management department, and design supervisor, the contract lock interface can be called through the engineering system to create PDF files and sign the process. After the completion of the drawing review, the verification personnel of the design institute will automatically check the signing message and pending process, and add electronic signatures by verifying the signing intention online. ④ After the verification and signing are completed, the design stamping personnel and the supervisor generate a pending signature process message in the business system. After verifying the signing intention, the contract lock electronic signature page can be called to stamp and review the seal, and the drawing signing is completed.

Scenario 4: Electronic signature of "Engineering Monthly Report and other report files"
Various daily reports, monthly reports and other report files in engineering projects are important project materials that need to be regularly submitted, approved and signed by the construction party before being archived. Annotations and annotations are required to be added and stamped by the construction and supervision parties. Through the application of electronic signatures, business personnel of construction units can now open the engineering management system and submit various engineering reports at any time. Relevant responsible persons can approve, stamp, and automatically archive them online. The entire process is paperless, without the need for multiple errands or manual sorting and archiving, making automation more convenient.
Detailed scenario description:
① Business personnel of the construction unit submit reports in the system, and the system automatically calls the interface to generate pending documents and the signing process. The person in charge of the construction party and the supervisor of the supervision unit shall check the approval message and submit approval opinions. ③ Use the form field function to automatically embed approval comments into PDF electronic files. ④ The construction and supervision parties check and stamp the pending message, complete the signing online, and archive the process.

Scenario 5: Automatic archiving and management of engineering data
Various contracts, documents, agreements, and other data files are important engineering archives that need to be organized and archived in a timely manner. The contract lock is integrated with the engineering system and archive system independently developed by East China Institute. During the archiving process, the signed data of engineering materials such as drawings, plans, and inspection and evaluation forms are synchronously transmitted to the archive system of East China Institute, helping to achieve automatic organization and archiving of engineering data archives for on-demand query and use.
Detailed scenario description:
① After the engineering data is signed, the engineering system automatically synchronizes the contract ID and other information of the contract lock platform to the archive system for storage, making it convenient for later contract document retrieval and query.   During the archiving process, the archive system of East China Institute automatically obtains the signed data such as the signing time, signatory, and original signed documents stored on the contract lock platform through an interface. The archive system will organize and archive the file data obtained from the contract lock platform through archiving rules.
