Krympress reports:
Proper planning for using technology is an art that not all project managers own. It would seem that it is complicated: I ordered a car, I arrived, it works. In practice, everything is much more complicated. Incorrectly planned technology turns from an assistant into a source of headache and extra expenses. Renting special equipment for effective work should be thought out as much as possible — gortehnika.ru. We understand typical miscalculations that even experienced foremen allow, and learn to avoid them.
Many people think that planning equipment is just to make a list of machines and order them for the desired date. This approach is guaranteed to lead to problems.
Ignoring the sequence of work
The most common mistake is to order all equipment at once, not taking into account the logic of the construction process. The result is predictable: the machines bother each other, idle, block driveways.
Incorrect priority for feeding technology
A classic example: the excavator is already digging a pit, and the dump trucks were ordered for the export of soil only the next day. The earth accumulates mountains, interferes with work, creates additional problems with the transshipment.
Or vice versa — the dump trucks arrived ahead of time and are standing in anticipation of loading. Simple equipment costs money, drivers are nervous, the schedule is lost from the first day.
Conflict of different types of work
The concrete pump cannot drive up to the filling, because the crane operates there. Auto -item blocks the passage for material locomotive. The compressor makes noise next to the place where accurate measurements are taken.
Such conflicts arise due to the fact that they plan each type of work separately, without thinking about mutual influence. But the construction site is a single organism where everything should work harmoniously.
Underestimation of spatial restrictions
Many order the equipment, focusing only on technical characteristics, forgetting about the physical dimensions of the site. As a result, the machine is either not placed or it works inefficiently.
Dimensions and maneuverability problems
A large excavator on a tight platform is a disaster. It cannot turn around, gets to neighboring buildings, creates a danger to people and structures. We have to change to a more compact model, but the same performance falls.
A truck with a long arrow seems to be a universal solution until it turns out that there is nowhere to install it. The supports rest against existing structures, the arrow touches the wires or neighboring buildings.
Lack of space for maneuvering
The technique should not only fit, but also be able to work normally. Razvosts, entrances for loading and unloading, security zones-all this requires additional space.
Often they forget about storage of materials. They brought crushed stone, but there is nowhere to pour out — the whole site is busy with equipment. We have to stop the work and drag the mountains of the material manually.
Inaccurate weather conditions
Weather in Russia is a factor that cannot be ignored. But many plan work as if outside the window is always a plus of twenty and the sun.
Seasonal restrictions on work
Bill concrete in winter requires special measures for warming up. Ordinary concrete pump may not cope with a thick mixture with anti -gun additives. We need more powerful equipment and additional equipment.
Earth works in rainy autumn turn into a nightmare. The soil gets wet, the technique is slipping, performance falls many times. What was planned for a week is stretched for a month.
Climate influence on performance
In the heat, the engines overheat, operators work less effectively. In winter, the technique warms up longer, more often breaks, requires more frequent service.
Windle weather limits the work of cranes. A strong wind — and the lifting technique is idle according to safety requirements. But a simple crane paralyzes half the construction.
Errors in calculating time costs
Revaluation of the speed of work
Many plan the time of operation of the equipment for maximum performance specified in the technical characteristics. In practice, the real speed of work is always lower than the passport.
The excavator can dig 100 cubic meters of soil per hour in perfect conditions. But at a real facility there are breaks for moving, waiting for dump trucks, a bypass of communications. Real performance turns out to be twice as lower.
The time of time for preparatory work
The technique arrived — and immediately to work? It was not there. It is necessary to instruct, show operators the features of the object, check the serviceability of the machine, prepare jobs.
Demobilization also takes time. Cleaning equipment, paperwork, loading for trawl-all this eats a precious clock, which for some reason no one puts on the schedule.
Insufficient coordination between participants
Lack of a single control center
Each contractor orders his equipment regardless of others. The result is chaos on the site. Cars interfere with each other, block driveways, create traffic jams and conflict situations.
The strawberry excavator does not know that in an hour a concrete pump of finishes will come. The construction of the constructive people blocks the entrance for the automixer. The compressor of plumbers interferes with the work of surveyors.
Communication problems
Information about the changes in the graph reaches the operators of the equipment late. The car came to work, and it turns out that the work was postponed to tomorrow. Or vice versa — the technique is urgently needed, and it is busy at another object.
This is especially acute when working with subcontractors. Everyone lives in their information bubble, coordination is completely absent.
Ignoring the technical requirements of the object
Discrepancy between characteristics of working conditions
We ordered a regular excavator for work in cramped basement conditions. The machine does not fit in height, you have to look for a special low -profile technique. And this is not enough on the market, it is more expensive, you need to order in advance.
The car crane was picked up by carrying capacity, but forgot about the shooting of arrows. It can raise the load, but install it in the right place. A crane with a large flight or additional rearrangement is required.
Increase in the features of the soil
The swampy terrain requires equipment on wide tracks or special supports. An ordinary car will just fail or get stuck. The rocky soil quickly wears out the cutting elements — we need reinforced buckets and additional protection.
The presence of underground communications limits the depth of digging and requires special caution. A powerful excavator can damage cables or pipes with one careless movement.
Planning the use of special equipment is a difficult task that requires an integrated approach and accounting for many factors. Mistakes at this stage are expensive and corrected with difficulty. It is better to spend time on a detailed study of the plan than then to get out of the consequences of hasty decisions. TO A quality planning is half the success of any construction project.
