Quanto custa fazer um casa em cocreto armado. ? QUANTO EU GASTEI ATE NA LAJE !

Summary

The video covers the cost breakdown and construction process of a concrete structure. The creator explains the steps taken to build the slab and walls, including the benefits of using concrete such as saving time and reducing costs by about 30-40%. He details the materials used, including rebar, concrete, and electrical tubing, and shares insights into the foundation, labor, and the overall efficiency of the method. The speaker emphasizes his experience and motivation, offering tips for others interested in replicating the process, while also engaging with viewers for further discussion and advice.

Takeaways

• 🏗️ The video discusses the construction process, focusing on the cost and steps involved in building up to the concrete slab stage.
• 👷 The presenter has chosen not to include the cost of formwork and his own labor in the calculation but includes his brother Lucas' work.
• 💡 The electrical and plumbing tubing is embedded directly into the concrete walls, eliminating the need for further adjustments later, which saves time and money.
• 🏠 A key advantage of concrete wall construction is the elimination of the need for plastering, as the walls are already perfectly straight and ready.
• ⏳ The presenter emphasizes that concrete construction saves 30-40% in time and cost compared to traditional brick construction.
• 🔧 Horizontal and vertical reinforcements are added at regular intervals inside the concrete walls for structural integrity.
• 🧱 The house is being built without the need for traditional brickwork, columns, or plastering, and the presenter is using solid slabs and concrete for the entire structure.
• 💰 The presenter shares detailed costs of various construction stages, such as $7,000 for foundation drilling and $20,000 for concrete foundation work.
• 🔨 The entire lower floor, up to the slab stage, cost approximately $48,000, excluding the presenter’s labor.
• 🎨 The presenter plans to complete the rest of the work, including painting and finishing, and encourages viewers to follow along for updates on the construction process.

Q & A

What is the main topic of the video?

The main topic of the video is the costs associated with the construction of a concrete slab (laje) and related construction processes, including labor, materials, and techniques.

Why doesn't the speaker include the cost of the construction forms in the expenses?

The speaker does not include the cost of the forms because they consider them a tool of the trade that can be reused in future projects.

What labor costs are included in the project?

The labor cost of the speaker’s brother, Lucas, who is helping with the construction, is included. However, the speaker’s own labor is not accounted for.

What is the advantage of applying electrical and hydraulic systems directly in the concrete walls?

The advantage is that the systems are integrated during the construction, eliminating the need to cut into walls later, which saves time and money.

How does using concrete walls help save on overall construction costs?

Using concrete walls reduces the need for plastering and minimizes the number of structural elements like columns, saving about 30-40% of the overall construction cost.

What is the difference between this concrete construction and traditional brick construction?

In traditional brick construction, processes like plastering and rebar installation are more complex, requiring additional time and resources, whereas concrete construction simplifies these steps.

What construction technique does the speaker use for the walls?

The speaker uses a technique where horizontal and vertical iron bars are placed at specific intervals (every 50 cm and 1.2 meters) within the concrete walls for reinforcement.

How thick is the speaker’s concrete slab, and what is the ceiling height?

The concrete slab is 10 cm thick, and the total ceiling height inside the building is 2.62 meters, with an additional 10 cm for the slab.

What method did the speaker use for the foundation, and what were the costs involved?

The speaker used 40 cm diameter bore piles (brocas) for the foundation, with depths ranging from 3 to 5 meters. The total cost for the foundation, including machinery and concrete, was 20,000 BRL.

How much did the speaker spend on the lower level of the house, and how does this compare to the overall cost?

The speaker spent 48,000 BRL on constructing the 108 square meters of the lower level, which includes the slab, walls, and labor. This gives an idea of the total cost proportional to the house size.
