The ultimate trick for increasing project profits – various approaches to combining permanent and temporary elements and their advantages and disadvantages. When it comes to combining permanent and temporary elements, this is truly a skill that engineers use in an era of low profits to maximize earnings. Managing a project is like living day to day; only by being thrifty can one lead a good life. Next, I’ll share with you the insights behind this, based on the mistakes I’ve made and the successes I’ve experienced. I. One-step approach for temporary roads: This is the method we use most frequently. It means treating the temporary roads used during the construction phase as if they were the base layer of permanent roads. For example, if the design calls for a cement pavement, we first prepare the lime-soil layer and the stabilized layer; the surface layer is not created yet, as construction vehicles will operate on this surface. Li: The benefits are tangible. Last year, we did the same thing on a logistics park project, saving a significant amount of money that would have been required to dig up the temporary roads later and rebuild the subgrade. Just transporting the waste by road saves nearly 200 truckloads; taking into account the cost of machinery usage and labor, this alone saves at least 300,000 yuan. The owner was also happy, as this reduced the total project duration. Disadvantage: But this is only possible if the plan doesn’t change! We suffered losses on one of our projects: work was underway when, due to adjustments to the pipeline network layout, several sections of the previously prepared \"permanent base layer\" had to be dug up. After the pipes were installed, those areas had to be backfilled and compacted, which certainly wasn’t as effective as doing it in one go. It took twice as much effort, without any savings in cost. So, the route has to be fixed before this can be done.
II. Temporary lighting and temporary fire protection: making use of existing resources”
Li: This method saves a lot of labor and materials. On a previous underground garage project, by doing this, we avoided the need for the subsequent steps of drilling holes in the ceiling and installing exposed pipes. A rough estimate shows that there is a shortage of over 5,000 meters of temporary wiring ducts as well as the corresponding labor. The workers work below; the lighting is good and it’s safe. Disadvantage: The risk lies in protection. Construction vehicles move back and forth, causing significant vibration. If one of the embedded pipes is damaged or blocked as a result of subsequent work, it will be difficult to run wires through it later, making the situation even more troublesome to handle. Therefore, proper protection of the finished products is essential; dedicated personnel must be assigned to conduct inspections and make proper markings.
III. Turning temporary drainage into a resource”
Li: This trick is truly a ‘game-changer’ for the rainy season. I remember very clearly that the summer before last there was a lot of rain; the construction site next door had four or five pumps operating day after day, pumping water out with a constant ‘thumping’ sound. At our site, since we used a combination of permanent and temporary structures, there was much less water accumulation, so we only needed two pumps to handle the situation. After one rainy season, nearly 80,000 yuan was saved on electricity costs, water pump rental fees, and labor costs. The construction site isn’t that muddy, and the image of civilized construction is good as well. Disadvantage: Similarly, the layout of the pipeline network must be finalized. If there are design changes later on and the location of the piping network is altered, all the investment made in the early stage will be wasted, resulting in even greater losses. Therefore, this can only be done when the drawings are very stable and there is strong support from the owner.
IV. Make the most of temporary facilities and temporary buildings”
Li: This really saves money. Our company now has a set of standardized, reusable temporary facilities; when a new project starts up, the cost of using these temporary facilities can be reduced by 40% compared to building everything from scratch. Moreover, installation and removal are both quick, which facilitates rapid commencement of work. Disadvantage: The initial investment is high, and the company must be willing to spend this amount of money. Moreover, there are losses during the transfer and transportation process, so a place is needed for storage, which increases management costs as well. If the project locations are too spread out and shipping costs are too high, it may not be cost-effective.
V. The permanent fence shall be constructed in advance to serve as a barrier during construction. Method: The permanent fence should be constructed in advance, built at the designated boundary lines according to the specifications for permanent fences, to serve as the fence during the construction period. Advantages: It saves costs related to construction barriers, enhances the appearance during construction, and improves the image of civilized construction. Disadvantage: This matter needs to be discussed with the property owner in advance, so as to determine the method for constructing the fence ahead of time. We’ve suffered losses because of this – in one project, the temporary fences were built as if they were permanent ones, but the client refused to acknowledge that and demanded that the design be changed, forcing us to cover the costs ourselves in the end. By the end of the conversation, it was said that combining Yonglin strategies is like playing chess – one must consider three moves ahead when making a move. What it tests is not whether we can save money, but rather whether we have foresight and whether communication between different specialties is smooth. Used properly, it is the “invisible engine” behind a project’s profitability” ； If not used properly, it might turn out to be a costly mistake. Now, every time a project planning meeting is held, the first thing to do is to gather the technical, production, and cost management teams together and examine the overall layout diagram, asking, \"Guys, where else can we extract more value from this combination of permanent and temporary elements this time?\" ” In an era of slim profits, being able to handle such matters effectively is often the key to whether a project can survive.
