Indian construction industry is mature and has its set practices and systems. However the need for extensive innovations in the technologies has been realized due to problems such as low productivity, many construction waste and materials, worker’s accidents that are caused by the labor intensive works performed in job-site. To solve the problems, advanced technologies such as industrialization, prefabrication modularization, mechanization, automation and computerization have been researched and developed with concepts and methods to improve quality and productivity. The construction systems aimed to change styles of building construction to that of factory production through sophistications of developed technologies, methodologies and concepts.
Precast is an industrialized way to build residential and commercial building safely and affordably. This improves productivity, quality and shortens construction time of a building thus lowering total construction and lifetime costs. It is a suitable solution for both indoor and outdoor production and can be made into any shape or color and finished with several techniques. Compared to cast-in-situ, precast uses less of everything – less cement, less water, less steel, and less labor. It produces less waste on the site and in the factory. This makes CO2 footprint of precast much smaller than in cast-in-situ construction. It can be used as only building material or also as a composite structure. It also offers healthy and safe working environment. This together with longer spans gives architects and designers more freedom than ever in designing and building beautiful modern structures.
Formwork Technology is a revolutionary aluminium formwork construction system extensively in India. It is a unique formwork in which all walls, floor slabs, columns, beams, stairs, balconies, together with door and window openings are cast in place in a single site based operation. Formwork systems make use of concrete as the principal building material for the prime reasons of cost and accessibility. All types of concrete building structures can be constructed using this technology making the structures very strong, accurate in dimensions and tolerances with a high quality finished concrete surface resulting in the structures which are adaptable and very cost effective. It can help overcome the challenge of unskilled labour and increasing labour costs. Moreover this system can be reused over 250 times making it ecofriendly.
Jump Form Construction
Jump Form concrete core construction has become the dominant method of constructing core walls in multi?rise structures. It is a fully automated technology, the applications of which have witnessed innovative refinements to keep up with the changing face of modern day developments. These include improved hydraulics, improved set up arrangements that allow faster set up times, and material advancements. This construction method reduces the cycle time and increase speed, reduces tower crane dependence, site labour, enables simplification of floor construction and leads to major direct and indirect savings in project cost.
Contour Crafting (CC) another innovative research is a layered fabrication technology that has a great potential for automating the construction of whole structures as well as sub-components. The potential applications of this technology are far reaching including but not limited to applications in emergency shelters, low-income, and commercial housing. This technology has the potential to build houses with all utilities in no time with superior surface finish and enhanced fabrication speed. CC combines conventional robotics and innovative approach to building three-dimensional objects that allows rapid fabrication. The material are extruded with precision to offer construction without waste, noise, dust or harmful emissions making it environmental friendly and sustainable. In a developing country like India it is the most feasible option as it can help to eradicate slums, reduce costs of construction and help boost the speed of construction. Moreover the automated robotics technology results in fewer labour injuries which prove to be safer option for both the worker and the environment.
Holistic strategies for new construction and building upgrades reduce energy bills, enhance comfort and productivity, and provide healthier indoor environments in residential homes and commercial buildings. These technologies enable industry professionals such as Architects, Structural Engineers, Contractors and Building Owners to do their jobs better, while achieving greater accuracy, efficiency and cost management. Modern technologies focus on optimizing collaboration and managing complex building programs and if adopted can speed up the construction process
