A large-scale business is probably a few years from planning to completion? I think it's been about ten years. Isn't it more than 5 years at the implementation stage? The biggest problem is the economic fluctuations over time. Even in public works, price fluctuations due to aging are allowed as a factor for budget increase. I think that the increase in budget will lead to the success of the business by analyzing the factors and taking regular measures without solving them as mistakes.
I shared it.
Not limited to large-scale businesses, there are many situations where the final cost will be enormous.
This problem can be found in a wide range of areas, from home remodeling and waterworks, homepage production to system production projects to stadium construction.
In a nutshell, the quote is sweet.
There are several reasons why it gets sweet.
(1) The price is reduced by looking at the complexion of the client.
(2) If the site does not eat at a high price, the sales staff or the person above will reduce the price.
③ In the first place, I am making an estimate that is too colander.
(4) When the actual work started, an unexpected part occurred, and extra money was required to deal with this.
⑤ When I started work, I noticed that the materials and construction period were insufficient.
⑥ Specifications and instructions change during work.
(7) It became impossible to secure the materials originally planned, and it was decided to secure another expensive material.
There are multiple reasons, such as, and in some cases this combined reason creates the cause of exceeding the budget.
Moreover, due to ②
⑧ The people at the site quit, and I couldn't get around well, and the material procurement and construction period were out of sync.
In such cases.
The National Stadium is a good example. At first, I asked a foreign designer, but I refused because it was too expensive, and even though I made a low-budget one by a domestic designer, I ended up starting without a roof because the construction period and construction cost were insufficient. ..
Since I made a half-finished product, I didn't have a pick-up after the Olympics and no users, so I decided to pay the maintenance fee for big garbage with tax.
If so, wasn't it okay with the first foreign design? I think. If construction started at that point, the construction period might have been in time.
It would have become a tourist attraction, and since it can hold events even in the rain or snow, it should have been used all year round as a venue for concerts and lectures, not just for sports. By doing so, even the construction cost, which was said to be high rather than the maintenance cost, could have been recovered at some point.
There is nothing wrong with being scared at the time of estimation.
