| The city of Dammam builds 24 new circular tanks  The destiny of a country and probably of the whole world changed at the drilling point no. 7, near the small Saudi-Arabian fishing village of Dammam (Saudi Arabia) on the Arabian Gulf, on 4 March 1938, the day when oil was found. A lot of oil indeed! The province around Dammam is alleged to own 25% of all the world's oil reserves. A small settlement soon gave way to a cosmopolitan city which merged with the surrounding towns and is now home to over 2 million inhabitants and the biggest oil company in the world, making a dramatic contribution to the country's welfare. The existing wastewater treatment plant with its 24 circular tanks now requires extensive expansion.The go-ahead for the extensive expansion of the existing wastewater treatment plant was the reaction of the Ministry of Water and Electricity to the increasing number of inhabitants in Dammam. The contractor entrusted with this task, SysTech (Riyadh branch), began the shell construction works in December 2010. The new structures will be hosted on three construction sites. Each of these will include two big aeration tanks (98.50 x 56.70 metres) with 6 coils across a width of 9 metres into which the water masses are conveyed. Beside these, there are four circular tanks (external diameter 39.90 metres with 40 cm wall thickness), two smaller circular tanks (external diameter 33.60 metres) as well as conventional technical rooms. 8 circular, in-situ-casted concrete structures will stand on a construction ground of approximately 400 x 500 metres; the final project will include the same facility on three construction grounds of about 60 hectares (85 football fields) for a total number of 24 circular structures. The structural works will be completed in phases. Approximately 200 men will work on the construction site starting from 2013. The project was realised in collaboration between PASCHAL team, SysTech and Eifics in Dammam, the PASCHAL trade partner for Saudi Arabia. PASCHAL adjustable-radius TRAPEZOIDAL GIRDER formwork (TTR) will be installed in Saudi Arabia for the first time. As the formwork enters the service on the construction site, all foundations have already been laid and many straight walls are currently being raised. write your comments about the article :: © 2011 Construction News :: home page |
