Item Description

Storage space Space required for site storage of steel reinforcement can be reduced by up to 20%

Steel Savings Potential to reduce steel reinforcement by up to 20% compared to Grade 500 steel

Logistics Up to 20% less trucks delivering reinforcements to site – frees up site space and saves crane, manpower & time

Site Crane Handles up to 20% less steel and frees up crane time for other construction activities thereby speeding up construction

Concrete Savings Reduction in structural element size is possible when used with appropriate grade of concrete and results in overall dead load being reduced

More usable space More �oor space is usable with column size reduction

Less formwork Possible to reduce formwork needed for Columns and Beams due to member size reduction

Lighter foundations Due to reduction in members size resulting in lighter super structure, foundation loads and cost can be reduced

Manpower - Steel �xing / Installation

Up to 20% less workers are required to install / �x steel reinforcement onsite

Improved Safety Site safety will be improved due to less material handling, steel �xing etc

Time reduction Overall time savings can be accomplished by factoring in the earlier stated bene�ts

Cost reduction Overall cost reduction can be achieved from reduced Material, Manpower, Construction Time etc

Environment Reduced – Construction noise, Fuel consumption etc

Steel mass for various reinforcement bar sizes
