Progress plan means a plan that lays out the progress of tasks, assignments, and events that will make the product satisfy the customer and expectations.
1, 2, 3, 4 levels of progress plan definition and division:
1) the first level of progress plan
a. The first level of progress plan, namely the project master schedule plan and the overall project integration network plan, is the overall time frame to guide the project work type of progress plan, which is the object of the project specialty, reflecting the duration of the project design, procurement, construction, commissioning, and the total duration of the project, is to meet the project schedule. It reflects the duration of project design, procurement, construction, commissioning and the total duration of the project, and is the most intuitive and basic manifestation of meeting the project schedule target. It is prepared by the control department, assisted by the construction department, design department, procurement department and production preparation department, approved by the project manager and submitted to the company for approval.
b, the first-level progress plan mainly involves control points: site preparation (demolition and relocation, "seven passes and one leveling", etc.), bidding, software package cycle, overall design cycle, foundation design cycle＼detailed design cycle, procurement cycle (inquiry＼ordering and delivery of key equipment such as long-cycle equipment and proprietary equipment), Site handover, piling works, civil construction, civil delivery and installation, installation of various specialties, construction of long lead time equipment, lifting of large equipment, mid delivery, linkage test, commissioning test, and production assessment. The total project progress plan in crosswalk (Gantt chart) format and supplemented by text description, the overall project co-ordination network plan should be used as a network diagram.
2)Secondary progress plan
a. Secondary progress plan is the device for the object of the total progress plan, is a carrier of the intermediate plan, on the one hand, it is a complement to the project level plan, on the other hand, it has a guiding role in the preparation of the project's three-level plan. It mainly refines the design, procurement, construction professional management and specific interface coordination management to ensure that it meets the requirements of the control points of the first-level progress plan and establishes more detailed control points.
b. The second-level progress plan mainly involves control points: basic design cycle, basic design review, EPC award, detailed design cycle of each specialty, design cycle of key equipment, procurement cycle of each specialty, procurement of long-cycle equipment, civil construction cycle, construction cycle of each specialty of installation, and delivery date. The secondary progress plan is prepared by P3 or Project software.
3) three-tier progress plan
a. Three-tier progress plan is a detailed implementation plan for the object of the installation for the establishment of progress detection benchmarks and tracking and testing. The three-level progress plan is broken down into divisional works and detailed to equipment bit numbers, piping systems, and electrical instrumentation categories.
b. The three-level progress plan mainly involves the control point content: professional construction drawings to arrive at the information, equipment and material arrival information, construction program approval information, civil engineering foundation by the time of delivery and installation, vertical start and completion time, equipment installation time by the time of installation, pipeline partition or system installation time, electrical instrumentation partition or classification installation time, anti-corrosion and heat preservation construction time. The three-level progress plan should reflect the logical and constraining relationships between activities, and indicate the critical routes and preparation instructions. Generally prepared with specialized software.
4) four-level progress plan
a. Four-level progress plan by the construction contractor to decompose to the sub-projects, detailed to the process level, updated weekly.
b. The four-level progress plan mainly involves the control point content: civil piling, pile testing, pile cutting, trenching, bedding, binding, supporting molds, pouring, acceptance, equipment welding, lifting, pressure testing, installation of internal parts, etc., pipe prefabrication and installation, blowing, pressure testing, electrical instrumentation cable laying, installation, debugging, etc..
c. The progress plan should indicate the sub-projects, the start time of each process, construction cycle, completion time, the main process handover time.
