【Haichuan EPC】Design Management in the Implementation Phase

Thread Content

III. Work during the project implementation phase is carried out on the basis of the project planning; by this time, the preliminary preparation, organization, and initiation tasks have been completed. It mainly includes: project design management, project procurement management, project construction management, project commissioning management, project risk management, project schedule management, project quality management, project cost management, project HSE management, project resource management, project communication and information management, and project contract management. 1. Project design management includes the design characteristics of EPC projects, the tasks involved in the design of chemical EPC projects, and design completion. (1) Design characteristics of EPC projects: ① High project investment and difficulty in estimating workload ； ②Long implementation cycle and high economic risks ； ③It is difficult to adjust costs outside the contract price ； ④Coordination and integration across all disciplines throughout the entire project lifecycle ； ⑤Closely interrelated with procurement, construction, and commissioning ； ⑥Closely collaborate with procurement to strictly control procurement-related documents, ensuring the accuracy of the information entered ； ⑦The project is complex, involves many participating entities, and requires a large amount of information exchange. (2) The design tasks for chemical EPC projects typically include the process design phase, the basic design phase, the detailed design phase, design coordination during the procurement phase, and design coordination during the construction phase. First, a team is formed and a project design meeting is held; the team is organized by specialty: process engineering, thermal engineering, water supply, drainage, and fire protection, analysis and testing, safety and hygiene, environmental protection, piping, pipeline materials, stress analysis, equipment, pumps, machinery, industrial furnaces, electrical engineering, telecommunications, instrumentation, general layout, architecture, structure, HVAC, storage and transportation, and project cost estimation. In engineering companies, there are generally two types of people: those who are experienced design managers with many years of project experience, and newcomers who possess the qualities of a design manager but have never had the opportunity to put them to use. Management faces the decision of whom to appoint as the project design manager; the usual approach is to assign an assistant design manager to work alongside the main design manager. Further, investigate the requirements for patent technologies and process packages, clearly organize the input criteria for new technologies and equipment, refer to the input criteria from similar historical projects or similar sections of existing projects, be familiar with the contract documents, their contents and scope, provide basic information, design standards and specifications as well as data, delivery requirements, and assessment and acceptance criteria. On the basis of the work carried out above, the design manager prepares a design milestone plan, while the various specialized departments formulate their own plans for progress in their respective areas. The design manager then consolidates these plans from different departments, makes logical adjustments to them, and submits them to the project manager as a comprehensive plan outlining the coordination between design, procurement, and construction activities.
