Modular Building Companies

Modular construction companies are coming up to meet the needs of the construction industry. They know the potential of this building method that uses advanced technology and mass production methods for building construction.

Modular construction is seen as a potential winner for the construction industry. Yet it has failed to take wings as expected. Modular construction companies have offered time and cost saving as the most important benefits. Shortage of skilled labourers in the construction industry also indicated a rise in moving from traditional to prefab and modular construction methods.

Major concerns

  1. The first concern relates to reluctance to move from a known, tried and tested method of construction to a new method. Whereas traditional construction is sequential the new method depends on working on all aspects of constructing buildings simultaneously.
  2. The second concern relates to the need to conceptualize, design, and prepare complete models of buildings before starting construction work. This requires bringing all stakeholders in construction work into the process at the initial stage.

 

What modular construction companies say about the new method?

 Rethinking and re-assessing building processes are the two most steps developers and project heads need to undertake when they go for modular construction.

They also need to consider the environmental issues and the storing space for units around the building site as soon as they decide on shifting to the new method.

Safety and security of the transported units is one more concern.

They need to keep workers on hand so that the unit assembly and installation is done concurrently.

Planning for modular construction

Before opting for modular construction you need to research the local circle for companies offering the facility.  These companies cater to a fixed area. Find the companies that supply to your area of construction.

Take a look at your building design and make sure it fits in with modular construction.

Finally, bring all the people you will need to during the entire construction process to collaborate in the project.

Modular construction works best when the design first and build later process is followed. Your contractors and you need to be clear about the job, time frame and finance involved.

As builders using the modular method for the first time it would be a good idea to hire consultants to handle the project for you. Ask your sub-contractors to visit the factory producing the modules to get a real feel of the work.

Companies have been known to construct high rises in as fast as in two weeks using the modular method. The buildings are strong and durable but also earthquake and fire resistant. Standard designs and reusable units reduce wastage of resources and add to the bottom line of both these companies and developers.

Modular technology has a long way to go. It is an evolving field that is yet to reach its highest form. As urbanization increases so will the need for rapid infrastructure growth. Modular construction companies are gearing up to meet this challenge.

Steps to modular construction

  1. Design:

Designing is vital to success in modular construction processes. It includes calculating the area to be covered, the number and types of modules required, and specifications of the exterior and interior requirements for the building.

  1. Engineer

Engineering the modules needs to meet set standards and regulations regarding building construction.

  1. Develop site

Site development in terms of constructing the foundation for the building and fabricating modules happens simultaneously. Foundations are of two types: on grade or full foundations according to the type of building to be built.

  1. Complete fabrication in factory

Factory production process is done under controlled and monitored conditions. The modules are built on to steel frames using hollow and insulated walls and sections that are fixed into place in the plants.

  1. Transport

Special transporters equipped to carry modules are used to transport the units to the building site. The types of module used and the type of project is considered in arranging transportation for the units.

  1. Install

Specialized constructors assemble and install modular units at the building site. Depending on the type of construction undertaken, cranes or mechanical methods are used to install the units.

Modular construction is a streamlined construction process. It makes construction work safe, easy and fast. Proper designing and engineering methods are essentials for modular construction. The future of construction will see extended use of modular construction all over the globe.

5 major benefits of Modular Construction

Modular construction that uses the factory line process of production has come to change the way the world builds. More and more projects and construction company owners are opting for this new technology driven method of building. Both commercial and residential projects find prefab construction attractive. The system works equally well for temporary as well as permanent structure construction. It is also well suited to expansion and extension projects for existing structures.

Here are five major reasons for modular construction to be gaining in popularity.

1. Quality Control
Production and manufacture of modular prefabs adhere to very strict quality control standards. The factory manufactured units, blocks, sections and panels share uniformity of size, shape, and finish since they are molded from pre-designed casts.

Material used in the manufacturing are pre-decided to meet quality control standards and codes.

Off-site factory production shields these modular products from exposure to the elements and proper facilities for storing in favorable conditions eliminates chances of warping and other deformities. Consequently the products maintain their quality standards for longer period of time.

2. Stricter Timelines
This method of construction ensures that it is carried out simultaneously at the construction on-site and in manufacturing facilities off-site. This dual site construction speeds up the project work as time is utilized more effectively and efficiently.

The slag time needed for setting in traditional construction leads to stoppage of work for a few days or weeks. This slag time is also removed in prefab construction thereby further adding to possibility of adhering to stricter timeline.

Teams of workers involved in prefab construction have proper technologically sound tools at their disposal for production of prefab units. The factory line process of manufacture produces units and blocks swiftly and with greater accuracy and precision.

3. Lower Costs
Cost reduction is one of the major advantages modular construction work enjoys. Decrease in build time impacts cost factors positively by reducing labor cost. The use of precision designs ensures optimal procurement and utility of raw material for manufacturing prefabs. This further adds to cost saving benefits of prefab construction.

4. Reduction in Waste Material
The residual waste left behind in traditional construction methods is greatly reduced in prefab construction. Prefab units brought to the construction site are exact in quantity. This reduces wastage of blocks. Preplanning and pre-designing also adds to reducing wastage of material. Uniformity of units leads to multiple use of similar units.

5. Environmental Benefits
The factory line production process means less energy consumption when compared to traditional construction. Waste products of prefabs are reusable unlike traditional waste that has to be discarded. Unused blocks and units can be stored and used in other construction projects or recycled into new units. This reduces the amount of material from traditional construction that ends up as landfills. The dismantling of buildings that use prefabs leaves less debris thereby bringing down environmental pollution.

These five factors have helped the prefab construction industry to forge ahead and create new standards in the field of construction.

Off-site Manufacturing in the Construction Industry- Explained

Modern construction methods include both on-site and off-site ways of constructing buildings. Traditional construction happens on-site while prefab construction is off-site construction. While on-site traditional construction is a well known way of building, modular construction is still an emerging area.

Success in off-site construction depends on meticulous planning and designing of parts of a building. We present to you here the details of off-site manufacturing in the construction industry.

What is off-site manufacturing?
We use the term off-site manufacturing to describe a process of constructing structures using prefabricated material manufactured away from the construction site and is transported from manufacturing facilities to the site for assembling.

How off-site construction works
The prefab parts are manufactured in plants under controlled conditions according to pre-designed patterns. The units that come in the form of blocks and panels are joined into sections on-site.  This assembly process is swift and produces a uniform finish. Buildings come up in very little time and show a better look than traditional construction.

Materials and methods of manufacture
Prefabs are manufactured using a wide range of durable yet lightweight materials and are available in various shapes, sizes, scales, and systems. Latest technology and dedicated software used in the manufacturing process add to the attraction of prefabs.

offsite manufacturing construction

Prefab range
Off-site manufacture produces sections of buildings, panels, individual units, and modular components that can be utilized in structural construction as well as interiors and enclosures and entire structures.

Modular prefabs
Modular units are the almost complete units manufactured in factory. They come as 3D units that are joined at the construction site to create service or structural parts of buildings. They come in two varieties- the re-locatable and the permanent. While the re-locatable variety caters to temporary construction and space needs and can be dismantled and transported to new sites, the permanent variety are closer to traditional construction that are manufactured in chunks.

Need for modular construction
Traditional construction divides construction responsibilities to different agents for various construction activities such as masonry, electrical connections, plumbing etc. The agents work with little coordination among them. Modular construction has all agents working as one team to complete a project inside out. The workforce for prefab construction is kept intact for across various projects creating team cohesion and understanding and speeding up work. Construction goals sometimes lead to compromise on quality of material. This subsequently raises the risk factor in construction. Pre-planned modular construction reduces the tendency by creating a balance between competing requirements.

Projects that benefit from modular construction
Projects with strict time schedules and need for least disruption during construction benefit most from prefab construction methods. High tech and repetitive projects also use prefab construction.

Once you know the pros and cons of on-site and off-site manufacturing construction you can decide the one you need to use for optimal productivity.  You may go for a combination of the two methods dedicating one part of the construction project to on-site work and completing the other parts with prefab building blocks.

Precast Structures – How are they used in Construction?

The concept of precast construction includes those buildings that are majorly made of components that are standardized and produced in a factory environment that is usually located away the site of construction. These materials are then transported to the site for assembly. They are manufactured by industrial methods of mass production that can help build a large number of buildings in a short time and at a low cost.  The main features of this construction process are as follows:

  • This includes the use of standardized tools, machinery and other equipment that is usually automated and can produce standard, interchangeable parts and products.
  • The division and specialization of human work force is an essential part of this process.

The entire conventional construction process is restructured to enable the interaction between the design phase and production planning. This helps improve the speed of construction. It is hence important to design buildings that have a regular configuration in plan and elevation.

Precast building systems are known to be more economical when compared to conventional multi-family residential construction.

Depending on the load bearing structure, precast construction systems can be divided into the following categories:

  1. Large panel systems
  2. Frame systems
  3. Slab-column systems with walls

Precast Infrastructure in India

Large panel systems
This refers to the multi-story structures that are composed of large wall and floor concrete panels connected in the vertical and horizontal direction. These panels enclose appropriate spaces for the rooms within a building by forming a box like structure.

Precast frames
Precast frames can be constructed using either linear elements or spatial beam column sub-assemblages. Precast beam column sub-assemblages have the advantage that the connecting faces can be placed away from the critical frame regions. Linear elements are generally preferred because of the difficulties associated with forming

Slab-Column Systems with Shear Walls
These type of systems rely on shear walls to sustain lateral load effects and the slab column structure resists the gravity loads. There are basically two main systems in this category. First, the lift slab system with walls where the load bearing structure consists of precast reinforced concrete columns and slabs.

All the precast structural elements are assembled by means of special joints. Reinforced concrete slabs are poured on the ground in forms one on top of the other. They are lifted from the ground up to the final height by lifting cranes. They are then moved to their final positions. Temporary supports are used to keep them in place until the connection with the columns has been achieved.

Pre-stressed slab column system
This type of precast system is a slab column system that uses horizontal pre-stressing in two orthogonal directions to achieve continuity. The reinforced concrete floor slabs fit the clear span between columns and after erecting the slabs and columns of one story, the columns and floor slabs are pre-stressed. The gap between the slabs is filled with in situ concrete and the tendons become bonded with spans.

The use of precast structures in construction will definitely revolutionize the way the construction industry works.

Infrasturcture

Offsite Manufacturing – the building process is taken away from the physical site to a controlled factory environment. There is a great improvement in terms of cost savings, time to deliver and the quality of the final structure.

Precast – this is the process of creating a construction product (a pillar, column or a beam) by casting concrete in a reusable mould. This is then cured in a controlled environment and then transported to the physical site and lifted to place.

Modular Construction – this is based on the idea of ‘assemble rather than build’. It brings about a paradigm shift in terms of infrastructure development – especially in the units such as hospitals, hotels and homes.

Above all, these techniques allow for more control over the final product and provide greater efficiency and speed of delivery. It also ensures that the final product is of the highest quality.

These methods are more appealing to the modern age infrastructure because, they are extremely cost effective, agile and sustainable with absolutely no compromise on quality.

The focus is to revolutionize technology and address the real world problems and provide innovative solutions that are sustainable – even in the long run. We believe in being the trends setters, path breakers and change makers to redefine construction!
