Practical knowledge of small building construction from contract to construction at a glance

Anyone who owns their own building is an object of envy.
Many people dream of building their own building and securing a stable future.
Of course, there are building owners who build great buildings as they wish and live a comfortable life, but the reality is that most building owners end up suffering great losses and regretting it because of buildings they built hastily.
If you want to build a great building and become the building owner you dream of, you must study architecture and have a good understanding of design and construction.
Without architectural knowledge, no matter how much money you have, you will never be able to build a satisfactory building.
It is always dangerous to jump into a field you are unfamiliar with.
In particular, construction is a job that requires a lot of time, money, and effort, so thorough preparation is necessary.

The three main players in the construction of a small building are the building owner, the architect, and the construction company.
However, the building owner is woefully lacking in knowledge compared to the architect or construction company.
It is a complete mistake to think that just because they are experts, you can leave everything to them and the owner just needs to prepare the funds.
If you fail to bridge the knowledge gap, you will be dragged around by architects and construction companies throughout the construction process, and in severe cases, you may lose all your money and time and ruin your life without even completing the building you dreamed of.

Architects and construction companies tend to move with the goal of maximizing their own profits, contrary to the building owner's desire to build a great building.
The building owner must acquire specific knowledge about how design is done, how to read design drawings, and what points of poor construction to watch out for during construction, and must thoroughly supervise the design and construction process.
From the moment you decide to build a small building, through selecting an architect and construction company, signing a design contract and construction contract, proceeding with the design, and constructing the foundation, frame, equipment, and finishing touches, until the building is completed, if you know the ins and outs of every process, you can avoid the numerous pitfalls lurking throughout the construction process and successfully create the building you've been dreaming of.

Building a small building: If you know how to do it, there's nothing to fear.
Practical architectural know-how to prevent poor construction and maximize the value of a building.

When you first visit an architectural firm, be sure to consult with this in mind.
When visiting an architectural firm to build a building, the question you should avoid the most is, “How much does it cost per pyeong?”
Asking price per square foot in architecture is like saying, “I don’t know anything about architecture.”
For example, even if the building area is the same at 100m², the perimeter length varies depending on the structure, so the construction cost also changes.
In addition, construction costs vary greatly depending on various factors such as wall thickness, floor height, floor shape, and material quality.
Knowing these things in advance will allow you to ask more intelligent questions, such as, “What construction methods and materials would be best for building a building for 6 million won per pyeong?”

Things you must know when entering into a contract
If you look at the construction contract, it is very complicated with many details listed in a jumbled manner.
The problem with complex contracts is that they make it easy for the contractor to deceive the building owner.
In reality, one person does two tasks per day, but this is recorded as if one task is done per day, two days, increasing labor costs.
They also make it look like they are contracting at a low unit price by not including the cost of entry, interior design, and equipment in the construction cost.
In addition, the building owner must prepare countermeasures such as a balance payment, a defect repair performance bond, a delay penalty rate, and a construction right and lien waiver to prepare for future problems.

The most important method for checking the quality of rebar in structural construction
The skeletal work is the most important work responsible for the safety of the building.
Since this is a task of constructing a building structure with steel and concrete, attention must be paid to the quality of the materials and the work method.
Usually, when asked to check rebar materials, they only look at the thickness.
However, to properly understand the quality of the rebar, you must check all the information engraved on the rebar, including the country of manufacture, manufacturer, diameter, and strength.
If you look at the rebar, you will see 1 to 3 dots engraved on it.
This point indicates the strength of the steel.
General rebar (SD300~350) has 0~1, high-strength rebar (SD400), commonly called high bar (HD), has 2, and ultra-high-strength rebar (SD500) has 3.
Nowadays, it is recommended to build buildings using high bars or higher, but sometimes, they work with regular rebar or use Chinese rebar.
It is important to check the quality of the rebar to prevent poor construction caused by replacing the rebar.

Practical plumbing installation to prevent building cancer and water leaks
The leak repair itself is simple.
You can tighten or replace the leaking part.
However, it is extremely difficult to find the leak location.
If you don't find the leak, not only will the repair costs keep rising, but even a small leak can shorten the life of the building and cause its value to plummet.
To prevent defects, care must be taken in construction of water and plumbing works.
The main cause of leaks is not the water pipes themselves, but the area where they are connected.
Therefore, when laying water pipes, the principle is to install them in one line without any joints in the middle as much as possible.
When one-line construction is not possible, double-pipe construction, which installs water pipes and corrugated pipes together, makes it easier to replace them later.
Additionally, if you install a separate waterproof barrier in places where water pipes pass, such as bathrooms, steam rooms, and laundry rooms, it will be easier to find leak points.
At this time, the waterproofing barrier construction is specified in the design stage and the construction company is required to construct it.
This is because waterproofing construction is one of the construction projects that construction companies hate the most.
