Pros of Modular Building Construction

Modular building construction process is capable of constructing both simple and sophisticated buildings that meet designer and architect demands. The process additionally confirms to all regulatory standards and gives a smooth and polished finish to buildings.

This assembly line manufacturing system affords advantages that you will want to buy into.  Renowned corporations have utilized modular construction process for some iconic buildings worldwide. Recent modular buildings have come up as high rises of twenty to thirty story buildings.

Modular Construction

Three top pros of modular construction

  1. Greener Buildings
    1. Factory production of modules ensures cleaner environments at the construction site. It reduces resource wastage with its built to order system. Moreover it minimizes site disruption during construction.
    2. Reusable modules are easily dismantled and transported for reuse at other sites. Savings on resources and energy for construction is phenomenal.
    3. It eliminates trapping of moisture in new buildings as it uses units manufactured from dry material under controlled factory conditions.
  1. Faster Construction
    1. Traditional construction is a sequential process. Modular construction permits simultaneous work to be carried out on-site and off-site thereby reducing time of construction. this can save up to 50% of construction time
    2. There is no stoppage of work due to adverse weather conditions. 60 to 90% of construction work can be completed in factories.
  2. Efficient Working Model
    1. Manufacturing of units occurs indoors and in safe areas. This reduces risks of site related accidents. Developers and builders face fewer liabilities due to this safety feature.
    2. Use of BIM helps assess energy needs and identifies cost efficient methods that can be used.
    3. Collaboration and integration of systems and workers is made possible.
    4. Modular construction fits into a variety of designs. It can be used to add on to existing structures as well as to construct new structures.

Other advantages

  1. Stronger buildings: Modular buildings offer greater resistance to natural forces such as winds and gales. They are safer during earthquakes and other calamities.
  2. Maximum construction activity is completed off site reducing disruption. This is particularly valuable for construction at busy sites or sites that are highly active.

Permanent Modular Construction (PMC) Modules

This process prefabricates parts of buildings and assembles them on site into integrated structures. They can be delivered with all necessary fixtures and interiors to provide buildings that you can move into immediately after construction is completed.

Re-locatable Buildings (RB)

These are partially or completely fitted buildings that are designed to be reused at different times according to need. These are very convenient for building additional space temporarily. As they are pre-built pieces they can be transported as and when the need arises. They also afford great flexibility of design and specification.

Modular construction benefits all parties. For developers and architects the process offers both financial and quality advantages. For home owners the time saved and the ability to move in to completed homes as well as heat, fire and sound proofing are definite advantages to look forward to.


Offsite Construction – Exploring the new innovations in construction in India

Construction needs are on the rise in India. Like all other developing nations, India too requires infrastructure development. While housing development is a real time need for a rapidly urbanizing India, rural infrastructure developments include roads for better connectivity, healthcare facilities, as well as cheap housing options. The pressure on the construction industry is immense and the demand far outstrips the supply.

Introducing the new technological innovations is one way to bridge this demand and supply gap. Use of off-site modular construction offers a solution here. While traditional on-site construction cannot be done away with in totality, manufacturing modular units in factories off-site significantly speeds up the construction process.

A well known way to construct
Component manufacture has been a well known way to build for many centuries. While brick kilns produced bricks that were transported to construction sites for use way into the past, more recent developments have included using pre manufactured tiles for flooring and wall covering, sanitary fittings, doors and windows and the like.

Prefab construction enlarges the scope of this manufactured factory made units to all parts of a building.

The method
Factory manufacture methods are used for both two dimensional units like walls and panels and volumetric units and modular units.

The two dimensional units are installed on previously fitted metal or concrete frames onsite.  The volumetric units are completed in factories and fitted on full stand alone structures. They include full rooms, shower boxes and the like.  The modular building units are fully prepared in factories and only need to be fitted in at the construction site. They are part of the structural construction of buildings.

India’s usage pattern
The Indian construction industry has been using two dimensional units for a long time now. Floor panels and walls built in factories and set in place at the construction site are a common occurrence.  Property developers, particularly those that are involved in construction of large facilities such as hotels and hospitals, are already using the volumetric units. They use pre built bathroom and toilet units in their commercial construction. Residential construction uses kitchen units along with the other two units.

The structural modular units are the ones that need to be considered now. The structural units are larger and require space for transportation and storage. Not all construction sites can provide the infrastructure and road width needed to accommodate these units. developers keep this in mind when deciding on the feasibility of using them.

Factors that make off site construction attractive to developers
Developers using offsite construction for their projects have experienced many advantages: cost benefit, on time completion, durability, sustainability, uniformity, and workers’ safety being a few of them.

Limitations faced in offsite construction
The most prominent barrier to embracing off site construction is the orthodox mind set of developers. In addition, the initial cost escalation involved is off putting.  There is also a dearth of skilled workers competent in handling off site modular units.

Providing training and proper codes and standards will help popularize offsite construction in India
