Dubai has broken the Guinness World Record for the largest ever continuous concrete pour by volume for the second year in a row.

The pour was performed over 35 hours and 19 minutes, from May 18 to 20, by the UAE’s RALS Contracting and Alfa Engineering Consultants.

In all, some 21,580m3 concrete was poured over a project area of 1,915m2 at the average rate of 611m3 per hour. The feat took place on a mixed-use project in Jebel Ali, and was accomplished using 18 concrete pumps.

It also required 2,618 trips from trucks delivering the readymix cement, approximately 500 workers on site per shift, and a total of 2,700 tonnes of reinforcing steel rebar.

The Guiness World Record was received by Eng. Hussain Nasser Lootah, director general of Dubai Municipality, who highlighted how the authority has been working for years to regulate construction activities according to sustainable principles — to ensure the safety of buildings within its jurisdiction for both the benefit of the environment and the health of its residents.

The record pour was conducted using green concrete made using environmentally friendly cement materials, which were produced at three authorised readymix cement factories.

Lootah noted: “The Municipality has a comprehensive plan to ensure the achievement of this objective through creating awareness among the stakeholders in the construction industry, whether it is the contracting companies, consultancy offices or sub-companies or the owners.”

The project was managed by engineer Nabil Korbaj, who coordinated the logistics plan and led the team along with the consultant structural designer Gassan Korbaj, and architects Feroz Sharafudeen and Ubaidhullah Abdulkather.

The pour was a raft foundation for a residential building consisting of a basement, a ground floor and two upper floors.

Dubai broke the previous Guinness World Record in 2016 with a pour of 19,793m3 of concrete over a 42-hour period in the Al Barsha area of the city. Both of the procedures were supervised by Dubai Municipality.
