ITC One Colombo records largest ever single pour of concrete in a project Sri Lanka

A major concrete pour of 6500 cubic-metres was done at ITC One Colombo One project located on the 5.87 acres of land on Galle Face Road, Colombo - 01 adjacent to the Taj Samudra hotel, recently.

ITC One Colombo One project is a mixed use development project of two tall towers on the Galle Face road, consisting of 135 units of high-end residential apartments in a 224-metre tall tower and a five-star hotel of 350 keys in another tower of 140 metres height. The project has a unique feature of a Sky Bridge with a swimming pool at 100-metres height connecting the Residential Tower with the Hotel Tower. The major construction work in the project started in January with the mobilization of the general contractor, Larsen and Toubro Limited, a major engineering organization from India working in various countries across the globe. Subsequently Sri Lankan sub-contractors were finalized for the civil and structural work.

The Residential Tower which is the taller one is being constructed by International Construction Consortium (Pvt.) Ltd (ICC), a highly reputed Sri Lankan engineering construction company.  The major concrete pour is for the raft foundation of the Residential Tower in the project which has been done with some special features. As per the available records, this single pour of 6500 cum concrete is the largest pour in Sri Lanka. It is done with a special mix design of C50 grade concrete, the ingredients proportion being used first time in Colombo. The concrete pour has 1250 MT of reinforcement work. Concrete Core Temperature of 70 Degree Celsius was maintained throughout. The concrete was meticulously planned in segments for operational ease. Special care has been taken to ensure no inconvenience is caused to the neighbours and general public. Utmost care was taken in safety of the concrete pouring operations including risk assessment and implementation, strict traffic management, workmen welfare and it has been witnessed by the District Factory Inspecting Engineer of the labour department who visited the site prior to the pour. Safety requirements such as emergency arrangements including ambulance and male nurse, training workmen, work permit system, entry system were also meticulously followed. Adequate lighting arrangements were made to ensure easy working in the night shift.

Logistics arrangement including pour sequence, organizing resources, permissions were organized well in advance. The concreting was planned during the long weekend so that traffic is not affected. Concrete was taken from four batching plants with 86 transit mixers to achieve average pouring rate of 100 cum per hour.  We could achieve a maximum of 210 cum per hour during the course. Total pour of 6500 cum completed in 70 hours. Temperature control and pour control were under strict vigil to ensure high quality standards.
