Construction Techniques

Construction Techniques

Construction techniques are an important aspect of building and planning a new project. Whether you are building a house or an apartment building, there are many different methods you can use to ensure a successful building project. You can choose between a number of pre-engineered structures and pre-fabricated materials. Using these methods, you can speed up the building process and avoid unnecessary costs by not overbuilding structures. These structures are also perfect for repetitive cellular projects because they can be quickly assembled.

3D volumetric construction

Three-dimensional (3D) volumetric construction techniques can significantly reduce the time required to complete a project. These techniques use a factory-controlled setup to create three-dimensional units. These units are then transported to the site in modular form. These units can include basic structural blocks or fully finished rooms, complete with all the necessary facilities. Once they arrive at the site, they can be assembled quickly and efficiently.

Another advantage of volumetric construction is its precision. With 3D volumetric construction, larger modules can be prefabricated, resulting in a faster and more accurate construction process. This method also ensures that buildings are resilient to natural disasters. For this reason, the use of 3D volumetric construction techniques is especially advantageous for large, complex buildings.

However, this technique is not without its disadvantages. One of the biggest drawbacks is the lack of flexibility. Its limitations are the fact that it’s harder to predict the schedule for onsite construction. With volumetric construction, a modular building can be completed thirty to fifty percent faster than the same-sized building constructed with conventional construction methods.

Traditional construction methods require skilled and expensive labor and expensive materials. In addition, they don’t have the advantage of being monolithic. 3D volumetric construction techniques eliminate the limitations of conventional precast concrete construction and ensure a more consistent, predictable outcome. By eliminating these limitations, 3D volumetric construction promises to provide transformative benefits for the construction industry. It’s also easier to implement than traditional construction methods, as most of the construction is performed off-site.

Raft foundations

Raft foundations are a land-based construction technique that protects a building from earthquakes, liquefaction of soft soil, and settlement. In addition, the raft itself prevents damage to the foundation due to earthquakes. This type of foundation is ideal for earthquake-prone areas.

Raft foundations are usually used for high-rise buildings and large structures. These foundations can be designed to be more robust by using a limited number of strategically located piles. Using this technique, a raft foundation can achieve higher ultimate load capacity and lower settlement rates.

The design engineer will determine how much reinforcement is needed for the raft foundation. The reinforcement will impact the cost of the project. The biggest impact will come from the cost of purchasing, cutting, and bending the reinforcement, as well as the labour required to construct the structure. In addition to the reinforcement, carpenters will need to fix edge formwork and marine boards. The cost of these materials will be borne by the client.

Raft foundations are an ideal choice for sites with difficult soil conditions. A raft foundation bridges erratic deposits, reduces differential settlement, and distributes the total load evenly. In addition, a raft foundation distributes the weight of the building over a large surface area, resulting in a more stable structure.

Raft foundations can be used for residential and commercial buildings. The foundation itself is supported by a grillage or spread footing. The piles distribute the load between the soil and the structure, either through friction alone or bearing on both ends. Because a raft foundation is relatively soft, it is not recommended for high-rise buildings.

Compressed earth blocks

Compressed earth blocks are blocks made of compressed earth, or soil. These are made by compressing an appropriate mixture of non-expansive clay, inorganic subsoil, and sand. They are a cost-effective alternative to concrete and brick, and can be a great choice for many construction applications.

The process of compressing the earth results in a compacted block that is highly recyclable and has a low energy cost throughout its life cycle. The earth’s natural moisture content helps stabilize the block, which improves its mechanical resistance. It also alters the pore structure, decreasing the volume of pores and increasing the apparent density.

Compressed earth blocks are typically made of soil, which is locally-sourced and easily sourced. They can be made by either manual labor or by machine. The first machines for compressing earth into bricks were developed in France in the 1800s. A descendent of these machines was invented by Raul Ramirez in Bogota, Columbia, in 1952. The compressed earth brick technique is one of the most sustainable and creative types of earth construction.

Compressed earth blocks are very lightweight and can be used for a variety of construction applications. They are an excellent choice for buildings that require a lot of structural integrity. They also last a long time. These blocks can be poured into the ground or used as building materials. However, it is important to consider how the block is going to be finished. Some compressed earth blocks have grooves that have to be cut out of the wall, which increases the cost of finishing.

Earth block construction has very few negative impacts on the environment. It has low embodied energy and low CO 2 emissions. Compressed earth blocks can be used for both walls and ceilings, or to fill a wooden frame. They can also be used to surround a masonry heater. A well-insulated compressed earth block wall can provide excellent thermal regulation.

Superadobe

Superadobe construction techniques are designed to be simple and environmentally friendly. They were invented by Iranian architect Nader Khalili and are now used in many parts of the world. Rather than relying on conventional building methods, Superadobe constructions use sandbags filled with earth to form the walls of the house. They are also insulated and fire-proof.

Building with SuperAdobe construction techniques involves stacking long bags of earth and laying them on top of each other. Next, these bags are placed into a narrow ring, which creates a domed roof. The bags are secured in place with barbed wire. The construction process requires accuracy and precision. It is best to use a compass composed of two poles to ensure proper placement.

Superadobe structures can be covered with plaster or a layer of living grass. In some cases, the exterior of a Superadobe structure is covered with a layer of cement and earth plaster. Another system, called the Khalili system, uses an earth and cement plaster that doesn’t crack over time. Other methods have used living grass as a cover, though it is important to follow local regulations and climate conditions.

Several researchers have studied the performance of the superadobe construction technique. For example, Zhao et al. analysed the thermal, ventilation, and lighting aspects of a superadobe structure. While structural analysis is not required in this method, they did identify potential structural failure scenarios. They also proposed a new design process that involves using a galvanised steel frame and zincalum corrugated roof sheeting.
