How to Develop a Good Schedule for Engineering Construction Projects – Task Duration
Thread Content
I have been working in project management for a few years, but I know very little about on-site construction management, particularly regarding task timelines. I would appreciate it if colleagues could advise me on which tasks in construction projects can have their timelines shortened, what factors influence or restrict this, and which tasks’ timelines cannot be reduced
Draw a double-code network diagram based on the actual processes and time milestones; in such a network diagram, the critical path cannot be compressed, while non-critical paths can be compressed. It’s hard to explain exactly how to do it in just a moment; the instructor taught us during the secondary constructor training, and there are also many tutorials available online. To speed things up, one can 1. change the procedures and carry out multiple tasks simultaneously in parallel. 2 Increase the allocation of personnel, machinery, and resources. 3. I can’t recall it. . . . . .
Personal opinion: The most important thing is to clarify the logical relationships among the various steps in the early stages – relationships such as precedence, parallel execution, and causality. It’s necessary to determine which tasks must be carried out first and which can be done simultaneously. Additionally, it’s essential to ensure that the procurement of equipment and materials is properly handled, and that all the necessary construction design drawings and documents are available and meet the requirements for construction; these constitute the key aspects. Specifically, it is also necessary to consider carrying out the construction in a concentrated and complete manner, as well as making preparations for the necessary labor, tools, equipment, and materials (which also involves the issue of whether the construction and procurement contracts drawn up by the contractor are clear enough). Site layout management also needs to be taken into account comprehensively. Breaking it down, these include construction organization design, construction plans, etc.; among them, work hour planning is the most difficult to handle. Since it relates to construction quality and schedule, it’s difficult to say what level of skill the workers have after going through so many subcontracts. That’s about all I know for now; I’m looking forward to guidance from those who are more experienced – I’m still learning*. . . In unexpected situations, it’s not only necessary to take weather conditions and supplier issues into account; what’s most problematic are the sudden inspections by **the relevant department – those are truly annoying.
