The central deck, which sits over the main rail line, comprised pre-tensioned pre-stressed reinforced beams with a reinforced concrete slab over the beams. The bridge was founded on end bearing piles 0.4 m in diameter and approximately 8 m deep.
Additionally, GIBB’s tasks included the installation of one metre high New Jersey parapets which were installed along the full length of each deck edge and the road-over-rail bridge, which is 31 m long has 3 spans: two of 11 m and one of 9 m in length. The deck was designed to be over 12 m wide to accommodate two 2.4 m surfaced shoulders and two traffic lanes 3.7 m wide.

Client:
Hilton Garden Inn
Location:
Gaborone, Botswana
GIBB’s Responsibilities:
SVAI, a subsidiary of GIBB, was appointed for the design of the Hilton Garden Inn in Gaborone. The project was conceptualised as a complementary public space open to all at ground level, while two buildings blocks, the Hilton Garden Inn and the Commercial Block, rise on either side.
The design was made to be pedestrian-friendly which encourages access by the new Business District community and offers a pleasant area to enjoy a meal at the restaurant or a drink in the hotel’s bar.
The two buildings’ orientation for sunlight gain in winter and protection in summer, translates into major savings in energy efficiency and power consumption. This is a particular advantage given Gaborone’s temperature variations and air conditioning requirements.
