The need for land and space is growing steadily each day. The rise of global trade among all countries increases the demand for the transportation of goods from one place to another through maritime channels. Similar to land, maritime traffic is also increasing. To resolve this issue, construction professionals use floating caissons. Floating caissons can be used in the construction of seaports, docks, and harbours, which are essential places for loading and unloading goods from the sea. Let us explain in detail the ways floating caissons work, their applications, advantages and disadvantages, the materials used for making caissons, and the construction process.

What is a Floating Caisson?

The floating caissons are prefabricated concrete constructions with cylindrical voids or chambers that resemble boxes. They are made with specialised equipment called “Floating Docks.” These caissons’ proportions are customised to fit the unique requirements of every project while staying within predetermined bounds. Floating caissons facilitate international trade by expanding the ports and also supporting the construction of ship vessels and protecting against wave action and the transfer of goods. 

These caissons can be used to do different kinds of marine work. They are mentioned below:

• Ports 
• Breakwaters
• Wharves
• Berthing Facilities and Docks
• Dry Docks and Slipways
• Fishing Ports and Marinas

How do Floating Caissons Work?

During building and installation, floating caissons use their buoyancy to function. With steel and reinforced concrete reinforcements, these massive, hollow concrete buildings are constructed off-site or in dry docks and are intended to float because of their hollow nature. Once built, tugboats or other propelling devices are used to float the caisson to the intended destination. 

The caisson is ballasted with water or heavy materials like sand or gravel after it arrives at the installation site to sink it to the necessary depth. It settles on the seafloor as it sinks, giving future construction projects like piers and bridges a solid foundation. To guarantee stability against waves, tides, and currents, the caisson is secured to the seabed using piles, cables, or other techniques after it has been positioned. After the caisson is anchored, further building tasks, such as adding utilities or superstructures, can be carried out on top of it. 

The caisson can then be joined to other caissons or structures to provide a wider platform for the construction project, and additional ballast adjustments can be made to guarantee the caisson stays level and stable. All things considered, floating caissons use buoyancy to facilitate transportation and accurate positioning, offering a sturdy base for maritime construction projects.

Applications of Floating Caissons

A variety of maritime works and harbour structures are built using floating caissons, which include harbours, wharves, dry docks and slipways, berthing facilities and docks, fishing ports and marinas, breakwaters. These structures rely on caissons that create sturdy, secure foundations to endure the harsh marine environment, such as waves, tides, and currents. Because they provide dependable support for large loads and maritime operations, caissons are crucial to the security and operation of important maritime infrastructures.

Advantages of Floating Caissons

• Because of their tremendous load-bearing capability, floating caissons are perfect for sustaining large, weighty structures like piers and bridges.
• They provide flexibility in areas where conventional foundation techniques would not be practical due to their adaptability to deep-water construction.
• For large-scale marine construction projects, floating caissons may be more cost-effective than traditional deep foundation techniques, despite the initial installation being more expensive.
• Project durations are accelerated by the prefabrication and floating capabilities, which shorten on-site building times.
• Sensitive ecosystems benefit from them since they disturb the marine environment less than pile-driving methods do.
• Because floating caissons are simple to move or reposition, they can be adjusted to accommodate shifting project needs or site circumstances.
• They are dependable in difficult situations because they are less impacted by changing soil conditions.

Disadvantages of Floating Caissons

• Floating caissons can be expensive to construct and install, particularly in deep water or challenging environments.
• The installation process is complex and requires specialised equipment, increasing both time and cost.
• They are less suitable for shallow water or low-depth areas where other foundation methods may be more effective.
• Floating caissons are vulnerable to environmental forces such as strong currents, waves, and storms, which can impact their stability during installation or use.
• Significant noise and vibration can be created during the installation process of floating caissons, which causes disturbance to marine life and nearby communities.
• Due to their location in water, regular ongoing checks are required to confirm their structural integrity.
• During installation and relocation, they may cause environmental impacts, such as disruptions to marine ecosystems.
• Floating caissons require precise positioning and anchoring, making them sensitive to changing field conditions and weather.

Materials Used in Floating Caissons

The equipment and resources used for construction activities around floating caissons are as follows:

• Concrete
• Sand
• Reinforcements
• The floating dock that holds concrete delivery pipes and a crane
• Auxiliary floating platforms
• Batch plant
• Concrete pumps
• Gantry crane
• Loaders
• Air compressors
• Pneumatic pumps
• Workmen on a shift basis

Construction Process of Floating Caissons

Step 1: Concrete Preparation

Preparing the concrete is the first step in the caisson prefabrication process. Two distinct equipment configurations work together to manage various steps in the process. The following are the steps: A batch of concrete is created in a mixer and then moved into a hopper that is attached to a concrete pump. A delivery pipe that is situated above the work platform then carries the concrete.

Step 2: Slab Construction

Starting with the base slab, each caisson is built in an ascending order. After being prepped on a secondary floating platform, the slab’s reinforcing structure is moved to the floating dock. The slab is formed as one unified piece using a movable mould.

Step 3: Building the Upper Sections

With the use of a movable mould, work on the higher portions of the caisson begins once the slab is finished, moving upward in one-meter intervals. In each step, the concrete is poured and compacted, the mould is adjusted, and reinforcing is installed. Until the caisson reaches its maximum height, this procedure is repeated.

Step 4: Releasing the Caisson

When the caisson is finished, it is released from the floating dock by disassembling a specific support and locking bar system. With the help of tugboats and ropes anchored on the coast, the caisson becomes buoyant and is guided to its destination.

Step 5: Final Placement and Filling

Granular materials fill the cylindrical spaces inside the caisson when it reaches its final place. Support vessels that are outfitted with the material and a specialised crane for its transfer are used to complete this task. 

Step 6: Preparation for the Next Caisson

On top of the caisson, equipment like trucks, loaders, tractors, and bulldozers finish the filling operation. Meanwhile, at the floating dock, work on building the next caisson begins.

Conclusion

To sum up, floating caissons give stability and support in deep-water settings, making them a dependable option for marine building projects. They are perfect for construction like ports, breakwaters, and offshore platforms because of their ability to float, enabling convenient transportation and accurate placement. Floating caissons are regarded for their great load-bearing capacity, versatility, and longevity, making them crucial for current harbour and infrastructure development in maritime settings, despite installation obstacles and the requirement for specialised equipment.

FAQs

Many people consider building their own home to be their life’s ambition. Although there are many different kinds of buildings, 2BHK homes are the most popular and useful choices for relocating. 

Are you planning to build a two-bedroom house in a village but worried about the cost? This blog gives a clear overview of the 2BHK construction cost in the village and the important aspects that need to be considered.

Understanding Construction Costs for a 2BHK House

Understanding the construction cost is crucial for preparing the budget and planning the finances. It ensures that the project is financially sound throughout the construction process. There are numerous components and factors related to constructing a 2BHK house.

Key Components of Construction Cost

There are two different components of the construction cost: hard costs and soft costs.

Hard Costs

The hard costs of a building are the physical costs that occur during construction. They include labour, materials, equipment, site preparation, hiring subcontractors, and more.

Soft Costs

Soft costs, or indirect costs, are those that are not directly associated with the construction process but influence it. They include the cost of architects, engineers, and designers to prepare plans, designs, and blueprints and the cost of obtaining permits, licences, and clearances.

Factors Affecting Construction Cost

Design and Planning

Design and planning are important aspects of construction that help the building last a long time. This reduces the money and time spent on repair and maintenance. Architects and engineers take care of this designing process, for which they charge a fee.

High-quality materials demand a considerable price, which increases the initial cost but saves the cost spent on maintenance. On the other hand, low-quality materials reduce the initial cost but could increase the maintenance cost.

Location

The location where the construction takes place plays a crucial role in determining the overall cost. The cost of the land is a significant factor in deciding the cost of construction. Urban and metropolitan areas typically have higher land costs than rural and suburban areas. Based on the location, the availability of materials, cost of labour, construction regulations, and transportation costs increase or decrease.

Labour

Labourers associated with the construction process play a significant role in determining the overall cost. The number of labourers, location, construction duration, and the cost spent on labourers influence the overall cost of construction.

Economic Factors

Economic factors such as inflation, higher interest rates on financing and loans, and supply chain disruption could affect the cost and duration of construction.

Government Regulations

Construction codes are based on localities and change from one place to another. They affect the overall structural integrity, choice of materials, fire safety, and every aspect of the construction. This influences an increase in the overall cost of the building. The cost spent on permits, licences, and clearances is done by the local government only when the structure comes under the criteria, and this increases the overall cost.

Cost Breakdown for Building a 2BHK House

Land Cost

A 2BHK house could occupy a land area of 800 and 1200 square feet. The rural land pricing in India does fluctuate due to various factors such as locality, demand, and infrastructure; a more grounded estimate would suggest a typical cost range between ₹3,00,000 and ₹35,00,000. The cost of the land could be much less in rural locations than in urban and metropolitan areas.

Fees for Planning and Design

Typically, 3% to 10% of the construction cost goes on design. The architect’s experience and the unique construction design will determine the price of plot design, blueprint creation, and structural approval. 

Materials Cost

The quality and quantity of the construction materials and equipment required for the construction cover major portions of the budget. The purchase of materials could cost ₹8,00,000 to ₹ 20,00,000 for a 2BHK house, depending on the construction needs and quality of materials. 

Labour Cost 

Labourers associated with the construction process play a significant role in determining the overall cost. The labour cost could range from ₹2 – ₹5 lakhs depending on the skillset, experience, quantity, and location. Labour costs in rural areas are comparatively lower than in urban areas. 

Permits and Legal Fees 

To obtain construction permits, property registration, and other licences required to legally authorize the building, a fee ranging from ₹10,000 to ₹50,000 can be charged depending on the local building codes and the scope of the project.

Contingency Fund

A contingency fund should be allocated to cover unexpected construction expenses. This includes an increase in material cost, design changes, or other additional requirements. The building’s contingency fund ranges from 5% to 10% of the total cost.

Average Cost of Constructing a 2BHK House in a Village

Considering that the building is a 1000-square-foot house, here is the cost of constructing a 2BHK house in that land area in a village.

Factors	Approximate Cost
Architectural Design	₹15,000
Brick Wall without RCC	₹800 per sq ft
Brick Wall with RCC	₹900 per sq ft
Civil Works (Construction)	₹1,500 per sq ft
Electric and Plumbing Installation	₹2,500 per sq ft

FAQs

In modern-day construction, lightweight aggregate offers a solution to reduce the weight of structures without diminishing their strength and durability. The materials of lightweight aggregates are less dense than traditional aggregates. This helps produce lightweight concrete and is preferred by many builders for various structural and non-structural applications. This article dives deep into the subject matter of lightweight aggregate and what role it plays in the construction sector.

What is Lightweight Aggregate?

It is a rough aggregate used in the production of lightweight concrete products. Some concrete products are concrete blocks, structural concrete, and pavements. The shape of the lightweight aggregate varies and some of the commonly available ones are cubical, rounded and angular. The constructor cannot neglect the shape and texture as insignificant as they both influence the workability of the structure. Lightweight aggregates can generally easily achieve the compressive strength needed for normal construction. Lightweight aggregates do not have a standard density value as the density value is often swayed by factors such as mixture proportion, air content, water demand, density and moisture content.

Types of Lightweight Aggregates

In the construction sector, lightweight aggregates have been divided into three types based on their origin, production process and application. These are:

• Industrial waste lightweight aggregate: This aggregate includes materials processed by industrial wastes such as fly, ceramsite, expanded slag bag, cinder, and light sand.
• Natural aggregate: This type of aggregate uses naturally occurring materials such as pumice (volcanic rock), scoria (volcanic material, much denser and darker in colour), diatomite (sedimentary rock), volcanic tuff (lightweight rock from volcanic ash).
• Artificial lightweight aggregate: This aggregate includes local materials like clay ceramsite, expanded perlite, and others. This also includes sintered aggregate, foamed aggregate, and processed by-product aggregate.

Applications of Lightweight Aggregate in Construction

• Lightweight aggregates are used in screeds and thickening, making the job of smoothing or thickening easily achievable.
•  It can also be utilised in screeds and walls where wood is fastened together.
• The lightweight aggregate can even provide resistance against fire and corrosion when castigated with structural steel. 
• The heat-resistant property of light aggregates makes them suitable for roofing as they act as a heat insulation material.
• It can even be used as an insulator for water pipes.
•  It can be used to make partition walls and panel walls in framed structures.

Properties of Lightweight Aggregates

• The compressive design strength of concrete that uses lightweight aggregate is 17-18N/mm^2 which is lesser in comparison to that of normal concrete’s compressive strength.
•  Again, the density of lightweight aggregate is lesser than normal concrete and the values range between 500 kg/m^3 to 1800 kg/m^3
• Lightweight aggregate can be in any shape including cubical, rounded and angular. The texture and form influence the workability of lightweight aggregate to a great extent.
•  Lightweight aggregates maintain low density and absorb little water.
• It has a high saturation level and can reduce the structural load, making it economically viable.
• The low thermal conductivity in them makes them the perfect option for roofing.
• Lightweight aggregates generally possess good acoustic properties.

Benefits of Using Lightweight Aggregate in Construction

Lightweight aggregates provide a number of advantages, making them an essential material in modern construction. The key noticeable advantages of lightweight aggregate are structural performance enhancement, reduced costs, and enhanced sustainability. Other key benefits in the construction sector are

• Lightweight aggregates reduce the load on foundations and structural elements by reducing the weight of the concrete. This makes them ideal for skyscrapers and long-span structures. The feature facilitates innovative designs.
• The reduced weight of concrete makes transportation easier and reduces labour and equipment requirements. In addition, they also make it easier for placement and shaping in precast and modular construction.
• The porous structure in lightweight aggregate produces thermal insulation, reducing heating and cooling costs in buildings. This makes the material suitable for places where temperature stability is crucial.
• Natural materials such as expanded clay or pumice provide excellent fire-resistance properties, enhancing safety and reducing the risk of structural collapse under fire conditions.
• Industrial-based aggregates produce a better option for the reuse of by-products with sustainable construction practices.
• The porous nature and flexibility prevent freeze-thaw cycles and at the same time prevent moisture entry and chemical attacks.

Manufacturing of Lightweight Aggregates

While the majority of aggregate materials such as clay, shale or slate can be substituted, in preparation the raw material is extended to twice its original volume. This helps to create a lightweight aggregate. The detailed procedure behind the manufacturing of lightweight aggregates is as follows:

Extraction: This step is also known as quarrying in which several crushers are used to crush the material. The finished product is then screened for quality.

Sizing: The finished materials are returned to the crushers. Thereafter, the material is recycled and moved to hoppers.

Reaction: The material from the hopper is moved into a rotary kiln at 1200 degrees Celsius. The carbonaceous compounds liquefy and form gas bubbles. These gas bubbles at high temperature expand the material.

Cooling: The clinker is cooled and shaped into a porous material. The lightweight aggregate material may be crushed again if necessary and is then stockpiled after it has cooled down. 

Conclusion

With their ability to fulfil the long-standing needs of structural efficiency alongside sustainability, lightweight aggregates seem to have been a transforming material in the construction domain. Reducing the structural load without weakening the strength, lightweight aggregates facilitate innovative ideas and cost-effective solutions within the realms of design capabilities. Applications from screed to roofing, fire resistance, and thermal and acoustical insulation, further bring out their wide scope and significance in construction. The use of natural and industrial waste aggregates further underlines the adaptability and eco-friendliness of the material, furthering sustainable building practices by using by-products and conserving resources. Lightweight aggregate manufacture requires advanced processes that are optimised to provide the right properties for modern construction requirements. Whether it is to be used for structural or non-structural purposes, lightweight aggregates become an imperative in achieving the goals of efficient, durable, and sustainable construction for the 21st century.
