- Contractor selection, contract
In the previous article, I told you that the most important thing when you pick up is to design a well-designed office and design it well.
The next thing is to meet this contractor. This is the second most decisive step in quality.
And ... design office. I can pick up what I want, but ...
It is really hard to meet a good contractor. This should work quite well.
Begin building the building in the early hours, meet the construction company from the pre-design stage first, meet with the design office recommending from the construction company
Or you may even go from design to design.
I've seen a lot of people who have built such a good house, but there are a lot of things to worry about.
Second, the design office may recommend a specific construction company.
This is less dangerous than the first, but you have to dig into it.
I am very talented and the design office is not tough, but the contractor really understands the design of our design office and does it well.
I like it if you like it.
The third is a case where the architectural office and the contractor have nothing to do with it.
It is when I find out the construction company by my hand, and when I go to the acquaintance by friend and the friend of my uncle crossing over, it is the case to choose.
In this case, it is good to do well, but if it is wrong, it is the worst choice.
I was shocked to hear that I had been talking about the last six architectural offices.
If you leave it to a local construction company and you can not afford a high-level detail design,
If you do not get the quality that you want, you will not be able to put it in the portfolio of the architectural office.
Especially if you are a local dealer who knows well around you, please try to check the performance and quality of the construction as much as possible.
Knowing this kind of builder You should ask the opinion of the architectural office when choosing to know.
The design office - builder - builder in building the triangle should help each other and check.
If the contractor and the design office are tweaked, it may happen that they do not know how to lose the owner.
Is there a strange part in the construction process? When the design office and the construction company say that they are at the same time ..
The owner is bound to accept.
What is lacking in design is that the contractor should be able to consult with the owner,
It must be editable.
In my case, it is the case that the construction company recommended construction company.
Originally, it's a normal process to pick two or three construction companies, get a quote,
Based on my experience of construction, I was recommended as an appropriate person in the architectural office.
Construction contract is direct contract construction contract? .
There is a way to contract the construction company (construction company) in a lump sum and leave the construction itself.
Secondly, there is direct construction. Direct construction is done by the owner himself. All responsibility is taken by the client
It is the way that the owner calls the people directly and carries out the work.
In fact, there are many people who really do this directly. But if you are not an expert, you will have many difficulties.
So I would like to say that I am a direct employee, but I employ a director who will do everything I do.
A contract has been made with me and the field chief (contractor). (Only 200m ^ 2 or less is available for direct construction.)
- Estimation
I decided to proceed with the construction company which already recommended in September, and received a quotation.
The maximum amount of construction I initially told the design office was 400 million.
But the estimates I received ... ㅠ,. ㄴ
As soon as I receive it, my eyes are dark.
You were surprised at the design office.
After reviewing once or twice at the design office, he said that if you sign a contract with a construction company with similar estimates, it would be 5,000 to 100 million more likely.
When you collect it, you are 10 years old. I was ready to be 10 years old.
I am about one year old at the quotation. ㅠ, ㅠ.
Money is a definite amount (the amount that can attract souls to the end of the construction)
Where and how should I reduce it .. I have to postpone construction .. Where can I get more loans? I was worried a lot.
As I mentioned in the first article, if the construction cost is 400 million, there are many other expenses such as design costs, furniture, appliances, landscaping, taxes and so on.
So, how can I reduce the amount of effort I've put in as tightly as possible
I tried to reduce my quotation as much as possible because I was able to borrow some wages so I could barely figure out how.
I will never get a hand in the financial sector.
I did not even think about reducing the size of the house. Because there is a lot of space that I gave up ..
(AV room (study room) was also bigger .., I gave up the pen tree room .. I made a small bathtub ..)
I want to change the material, reduce the window, remove it, remove it, and so on.
It's just barely ... down to 460 million.
The house is 60 pyeong and the attic is 10 pyeong.
It is estimated to be 460 million pyeong, or 700 pyeong per square meter.
So the contract is about 460 million. (Of course ... during the construction process .. ㅠ.
I mentioned this amount, but the structure of my house is unique, the insulation is thick,
I want to know what kind of high-quality materials I have applied.
If you control these things, you will be able to build your desired house if you have more than 600 lines per square meter. (Based on 2019 prices)
For reference, the amount per square meter may change in many cases for a number of reasons. It starts with the shape of the house, the material, and the number of toilets.
When you build a house with the same specifications, the smaller the house, the more likely it is to rise.
Even though the house is small, there is something that needs to be put in like a toilet, and the smaller the house, the higher the percentage of surface area that needs to be closed.
Another thing to think about is taxes. VAT.
You will need to add 10% of the quotation as VAT.
The same goes for design / supervision. Of course, if you pay taxes, I will issue you a tax invoice.
Please always consider the design contract, construction contract, and VAT status beforehand.
The construction quotation should be kept as detailed as possible. If you put a tile in a quote, how much tile you put in it
If you put a brick into a quote, you need a total number of bricks.
If there is a faucet, a bathtub is all possible, put the name of the model in front of it and hold the amount in advance.
As detailed as possible
.
This part is a little hard, but at the beginning of construction, what to use the toilet, what to use the door lock, it is not easy to decide what to use the wash basin.
So one way is to ask me to remove the things I will decide later from the quote
There is a way to live your own procurement.
I also asked for toilet / washbasin / tile / lighting / switch etc to be removed from the quote and buy it later.
So, when you decide the estimate, it will be 5 million won for tiles, 3 million won for wage, and 1 million won for miscellaneous auxiliary materials and miscellaneous expenses.
Kitchen tile A unit price per m 2
How many times per day
We need to get as much detail as possible, such as supplementary materials, cement, joints, human food, transportation, and so on. It is possible to make a settlement when something changes.
When lower material than desired material is received, it is possible to complete the complication.
The more detailed the quotation is, the more freer the contractor will be, and the more it is possible to write down my subordinate, etc.
It is also important to estimate how far you are going.
For example, if you do not estimate air conditioner construction, you can get more than 10 million won later.
If you do not include the entrance fee (such as electricity, waterworks, etc.) into the estimate,
Sometimes it goes in separately.
I would like to clarify whether furniture will be used in furniture construction from the time of designing, or whether it will be used for carpentry in construction work.
When a quote comes out, I usually get a down payment + 2 ~ 4 times of prepayment + balance.
5% of the down payment may be divided by period even if divided by period. I hold about 5 ~ 10% of the balance.
In the case of a residual balance, the contractor may receive the house after the completion, so after consulting the house,
It may be possible to pay with that money.
Usually, if the house is completed, it can be borrowed for 1 ~ 2 weeks.
Let's look briefly at the details of our work.
I can not tell you the details. I told you the total amount.
The construction company's profit excluding VAT is about 5%
Of the remaining 95%
Mechanical equipment construction accounts for about 5% (boiler, air conditioner, toilet facility, gas piping, etc.)
About 5% of electric installation works (electric works, telecommunication works, entrance expenses, various lighting fixtures, etc.)
Hypothetical / civil engineering work is about 5% (various fees, feeding, construction waste disposal, restroom, soil ponding cost, floor cleaning, etc.)
Reinforced concrete construction is about 22% (skeleton of house!
About 5% of insulation (extrusion method, bead method insulation cost)
Tile / stone construction is about 8% (our house is made of brick tiles and it is not a masonry cost but a tile cost ..)
11% of carpenters work on making interior frames of the house.
Metal construction is about 7% (Our house has a lot of metal on the outside.
