This concrete mix comprises about 30% recycled concrete aggregates
Tvasta, a deep-technology start-up, based out of Chennai and Bengaluru, has developed this indigenous 3DCP technology platform, which leverages automation and robotics for a faster, and more sustainable construction process, compared to conventional methods of construction. The new platform also offers the option of adopting modular off-site construction techniques. These factors can help reduce the overall carbon footprint for construction projects, and even improve safety by reducing the possibility of injuries to onsite workmen.
Proof Of Concept using 3DCP technology to create a sustainable and inclusive bus shelter
Addressing the growing needs of the Real Estate and Infrastructure sectors of India, Godrej Construction and Tvasta have collaborated to develop a Proof-of-Concept. The Bus Shelter was 3D Printed within a span of 32 hrs and assembled on site within 8 hrs. To promote adoption of Circular Economy principles in the Construction industry, Godrej Construction, along with Tvasta have developed for the first time a very sustainable concrete mix design comprising of approximately 30% of Recycled Concrete Aggregates (RCA), sourced from concrete waste debris, recycled at the Godrej Recycled Concrete Plant, at Vikhroli, Mumbai. The unique structure has a distinct physical design – a curvilinear geometry to showcase the aesthetic versatility, structural advantages and excellent potential that this technology has to offer to the Construction Industry. It is designed to be completely energy efficient with independent solar panels for lighting the bus shelter and it's commercial signages at night. The idea germinated during Godrej & Boyce’s ‘Sprint’ Initiative, an organisation wide intrapreneurial innovation program.Commenting on the introduction of 3D Construction Printing Technology Platform in India, Anup Mathew, Sr. Vice President and Business Head, Godrej Construction, said, "We are glad to collaborate with Tvasta, an indigenously developed 3D Construction Printing technology start-up in India. Godrej Construction is committed towards providing innovative and sustainably designed customer centric solutions for the built environment. Having jointly developed this pilot project, we believe that there is a great opportunity for us to leverage and scale-up the use of this new technology for the benefit of our stakeholders. To promote a Circular Economy, we have also jointly developed an innovative concrete mix-design that uses a significant proportion of Recycled Concrete Aggregates (RCA) as a part of the raw material used in the 3DCP Technology. This newly developed 3DCP concrete mix offers great promise for developing and using construction materials with a lower embodied carbon, which can help us design and develop innovative solutions for a more sustainable built environment. Our endeavor will now be to jointly engage with key industry stakeholders for exploring appropriate opportunities for the deployment of this 3DCP Technology, which even globally is still in a relatively nascent and evolving stage of development.” Currently, Godrej Construction is an Rs 1,000 crore business of Godrej & Boyce, is looking to scale up its offerings in the construction sector.
Vidyashankar C, Co-Founder and COO, Tvasta added, “We are happy to partner with a pioneer and thought leader in the building materials sector such as Godrej Construction. We are optimistic that this synergy will aid in the rapid scale-up of our technology platform. In turn, this will undoubtedly, extend the range of construction solutions that Tvasta offers for the many distinct use-cases in the country.”
Handling concrete better
Efficiently handling the transportation and placement of concrete is essential to help maintain the quality of construction, meet project timelines by minimising downtimes, and reduce costs – by 5 to 15 per cent, according to Sandeep Jain, Director, Arkade Developers. CW explores what the efficient handling of concrete entails.Select wellFirst, a word on choosing the right equipment, such as a mixer with a capacity aligned to the volume required onsite, from Vaibhav Kulkarni, Concrete Expert. “An overly large mixer will increase the idle time (and cost), while one that ..
Elevated floors!
Raised access flooring, also called false flooring, is a less common interiors feature than false ceilings, but it has as many uses – if not more.A raised floor is a modular panel installed above the structural floor. The space beneath the raised flooring is typically used to accommodate utilities such as electrical cables, plumbing and HVAC systems. And so, raised flooring is usually associated with buildings with heavy cabling and precise air distribution needs, such as data centres.That said, CW interacted with designers and architects and discovered that false flooring can come in handy ..
The Variation Challenge
A variation or change in scope clause is defined in construction contracts to take care of situations arising from change in the defined scope of work. Such changes may arise due to factors such as additions or deletions in the scope of work, modifications in the type, grade or specifications of materials, alterations in specifications or drawings, and acts or omissions of other contractors. Further, ineffective planning, inadequate investigations or surveys and requests from the employer or those within the project’s area of influence can contribute to changes in the scope of work.
