Structural Mastery at Tabora Station: BEWS’ Expertise Shines in the Standard Gauge Railway Line’s Main Hub. Explore the Design Excellence and Innovative Construction Solutions

BEWS has developed the structural design of Tabora Station, the Lot 3 main station of the Standard Gauge Railway Line. This lot comprises the section from Makutupora to Tabora along a total of 294 km of railway line, and a total of seven stations: four small stations, two medium stations and Tabora, the bigger and main station. 

The project has consisted of the complete calculation of Tabora Station, the coordination with ATU and MEP disciplines, and the development of the BIM model of the structure with a modelling level of LOD 300.   

Tabora Major Station design has involved the calculation of four different elements or structures: the station building itself, which corresponds to the main building; the MEP Buildings, two smaller buildings annexed to the main station where the equipment and the facilities are located; the platform and canopies; and an access underpass that connects the major building and all platforms with the freight yards facilities, only for the authorised staff. 

Tabora station is three stories building, mainly executed with reinforced concrete. It has a rectangular shape in plan of 103 m long and 45 m wide. The height is variable from 10 meters on side modules to approximately 14 m in the central module. Structurally, the building consists of a flat slab in reinforced concrete supported by rectangular concrete columns regularly separated in both directions (9,00 meters). The foundations of this building are isolated reinforced concrete footings. Two different concepts for the roof have been defined: one the one hand, a concrete slab of 0.35 m thickness and on the other hand, a double span (18,00 meters) atrium roof using a steel truss.    

To avoid all issue related to the expansion joints construction and maintenance, it has been proposed to design the main building without using those expansion devices.  

Tabora Station has been calculated to resist the seismic actions, the vertical loads corresponding to a public building and the shrinkage loads. An accurate staged construction model has been performed to analyse the effects of the shrinkage and to define some curing strategies in order to minimize initial shrinkage effects and achieve a good quality result.
