Prefabricated House - Optimal Cost Solution in Business

Along with the development of economy and production, more and more enterprises, factories and enterprises were born, leading to the need to use prefabricated houses to make factories, warehouses, offices... In addition to the manufacturing sector, the trend of using prefabricated houses for housing, restaurants, cafes, representative offices/displays or inns and rentals is also very diverse. Grasping that demand, Hoang Sa Viet Construction has boldly provided prefabricated house construction and installation services to serve customers.

What is a prefab house?

Prefabricated house, also known as pre-engineered steel building, steel frame house, Thai roof house, prefabricated house, is a type of house built with a steel pillar frame and installed according to a technical architectural drawing and installed. complete placement at the location requested by the owner. In which, a complete pre-engineered steel building product is made through 3 stages:

– Step 1: Brainstorm ideas and complete technical design drawings.

– Step 2: Producing and processing components at the factory based on the technical design.

– Step 3: Transport the components to the construction site and complete the construction.

Technical design of basic prefabricated house

Why are prefabricated houses leading the way? Advantages/Disadvantages of prefabricated houses

Compared with traditional houses, prefabricated houses have many outstanding points that make this model gradually become a construction trend, which is shown in the following comparison table:

Advantages of prefabricated houses

1. Cost saving

Like the previous two models, when building a prefabricated house, it will be more cost effective than classic house models, but the price of this house model in general will not be as economical as a prefabricated house.

2. Save time

The construction process of this house model is very fast, because the structures and joints of the prefabricated house have been carefully measured and handled at most stages at the workshop. Therefore, the construction process will be shortened.

3. Good bearing capacity

Assembled with sturdy steel bars, prefab houses have the same storm resistance as conventional reinforced concrete houses.

4. Can be combined with other structural accessories such as: elevated walkways, mezzanine floors, crane beams with flat floors on the roof, partitions, racing roofs, roof frills... Especially, pre-engineered steel buildings also help better drainage thanks to the system of vertical termite roofs, roof frills.

Prefabricated houses are considered as extremely flexible house systems, meeting all the necessary functions of a building. Thereby, this model becomes the reason that businesses should choose pre-engineered steel buildings to use as warehouses, factories or offices for rent...

Disadvantages of prefab house

1. Easy to corrode, rust

Because they are made mainly of prefabricated steel, this type of house is often susceptible to corrosion and rust. It is necessary to paint the outside to protect and increase the aesthetics.

2. Poor fire resistance

When at a temperature of 500 - 600 degrees Celsius, the steel will melt into plastic, reducing its strength and easily collapsing.

Application of prefab house

The steel structures of the prefabricated houses are pre-manufactured and then erected at the construction site, so the product completion time is very fast.

Constructions that often use this type of house include:

1. Factory, warehouse

2. Gallery

3. Multi-purpose house

4. Supermarkets, commercial buildings

5. Training center/conference center

6. Housing to live in

7. Cinemas

8. Hotel/resort/restaurant

9. Office/Representative office

10. Sports Center

11. Parking

12. Public buildings (schools, hospitals, churches, temples, museums, galleries, courts, ...)

13. Military service

Prefabricated house structure

The structure of a pre-engineered steel house includes the following basic parts:

1. House frame system (frame around the ribs, rigid frame for house construction, beam-shaped gable frame and support columns).

2. Purlin roof and purlin wall.

3. Bracing system, longitudinal struts, bracing against storms.

4. Other systems: roofs, roofs, ventilation systems…

Factors affecting the quotation process and construction cost of pre-engineered steel buildings

The selling price of a prefab house is calculated based on the following 4 criteria:

- Price of materials: Depending on the needs and purposes of use, most steel is used to manufacture the main components of the smart prefab house. As for windows, roofs, doors, etc., it depends on the material you choose.

- Size, area, number of building floors: the price for a finished product also depends a lot on the area and number of floors. It will directly affect materials, money and other expenses.

- Location: Depending on the difficult or easy terrain, the suitability of the land, the location near the center, etc., there will be different costs because transportation costs also play a significant role.

- Construction time: The construction time of smart prefab houses ranges from 2-8 weeks, but the simpler the design, the faster the finished product, the lower the costs incurred. From there, the price of smart prefab houses can be achieved at a cheap price.

Prefabricated house construction costs

The cost of a prefab house will add the following items:

- The foundation of the house: The mobile prefab house is manufactured up to 95% in the factory, so the foundation is also quite simple. The weight of each basic house (module) is from 1200-1300kg. So to make the house foundation, just make a concrete foundation neck 1m wide and have a concrete pillar 20cm wide to be able to put the house on it (4 pillars for each basic house). The construction of this ancient pillar you can do it yourself or hire a worker to do it. We will have drawing instructions to save costs for you.

- Price of basic house: Prefab house is calculated according to each module (piece). Each module has 2 main sizes: 3x6m or 4x6m optional. Each module will include a full system of frames, partitions, windows, doors in sets... All materials that come under the module can be calculated as a package for each unit (set/module)

- Toilet and kitchen rack: these two products will not be available in the prefab hostel, you have to add, you can install it yourself or you can order it with HSV so that our construction team will install it

- Transportation cost: The assembled inn has the characteristics of easy disassembly. So we can ship the goods to you easily, or we can deliver the goods to the site for you with actual costs.

Installation labor costs, including 2 types of costs:

- Travel and accommodation costs: for workers to the construction site (according to reality).

- Installation cost: The unit price for each module is 5 million VND (module/ unit).

With low cost, prefab house is an option to help reduce costs significantly. Due to the use of cheap but quality materials such as soundproofing, heat insulation, light cement foundation and walls, the cost of building prefabricated houses is much more economical than traditional houses.

Not only that, thanks to the fast construction time, you can also save a lot of money on construction costs when building a traditional house. This new home construction solution is also very environmentally friendly. It can be said that pre-engineered steel buildings are a satisfactory solution of economic and effective problems for investors in the process of finding the most reasonable construction solution for the project.
