Gadkari inaugurates cold mixer paver and patch-fill machine

Minister of Road Transport and Highways, Nitin Gadkari, inaugurated a unique first-of-its-kind mobile cold mixer cum paver and patch-fill machine, which has been developed indigenously by Central Road Research Institute (CRRI) to repair potholes.

According to the officials, the machine can repair 12-15 medium-sized potholes within one hour and is the best solution for roads and highway maintenance.

Gadkari stressed the need for developing cost-effective technologies for road construction by using locally available materials to reduce dependence on cement and steel.

Gadkari asked the road research institute to focus on long-span bridges and find ways to resolve the problems faced by bridge expansion joints.

He added that the research and development should not only end at filing patents but should also be commercialised to be available in markets, and more agencies use it for the construction of roads and repairing potholes.

The machine is a part of the Make in India initiative at Rs 30 lakh per unit, with a material cost of Rs 600 per tonne, compared to imported machines that cost Rs 2 crore with Rs 1,000 per tonne material cost.

CRRI officials said that the road construction agencies in India use the traditional method for repairing potholes by employing manual labour. The compact and low-cost pothole repair machine uses bitumen emulsion-based cold mix technology, which is self-propelled and self-contained.

Officials said that the machine would help in constructing roads in high-altitude regions where the design and construction of roads are challenging compared to plain terrain due to the non-availability of skilled labour and lack of space. It will also help in reducing carbon emissions and curb air pollution.

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. Ext..
