THE Cape Town office of Vela VKE has been responsible for the design and implementation of the city’s renewal programme for the upgrading and improvement of road signs. This has included the upgrading of existing and installation of new portal and T gantries on the various freeways in and around the city and airport; directional and regulatory signs in various areas of the city and street name signs in the city bowl.

The major work involves the dismantling of overhead signs and gantries under heavy traffic conditions; refurbishment and/or replacement of the component parts together with improved navigational information; construction and reconstruction of gantry bases and final erection/re-erection.

The widest portal gantry with a length of 30.3m, which spans five traffic lanes, has been erected over Buitengragt. An interesting point regarding the Buitengragt Gantry is that the original design position of the gantry bases had to be amended when the excavations for one of the bases revealed old tram-lines protected by the Heritage Act.

There are sixteen individual contracts in which Vela VKE has been involved, of which eleven have been completed to date. These contracts were completed on time and within budget, and the remaining contracts will be completed this month, ahead of the 2010 World Cup.

In order to accommodate new text, the signs on certain gantries have had to be increased in height whilst maintaining the minimum clearance above the road surface, resulting in eccentrically positioned signs on the respective gantry structures. With the prevailing strong winds in this area, special brackets were designed and installed to counter the wind forces on these signs.

Vela VKE is also involved in the design and implementation of two contracts for temporary signage for the City of Cape Town, one of which is to provide event-specific temporary navigational road signs for Cape Town CBD and surrounds during the 2010 World Cup. The other is to provide temporary navigational signs for public viewing areas, also during the 2010 World Cup.
