oa Civil Engineering = Siviele Ingenieurswese - Fortress pump stations : market contribution

 

Abstract

To counter vandalism, which robs owners of equipment worth hundreds of thousands of rands, pump stations are increasingly being built like fortresses, complete with thick reinforced concrete walls and roofs, and with small ventilation holes in the walls instead of windows or steel louvres, which are vulnerable to attack by angle grinders and oxy-acetylene torches. Consistent with these measures, the installation of self-supporting, heavy but easy-sliding 60 MP a concrete doors - SA Patent 2008/06587 - together with extremely robust locking mechanisms, are being specified more and more by consulting engineers. The concrete is completely immune to attack by oxy-acetylene torch, and the steel reinforcing in the doors is too dense for chisels to penetrate.
