Civil Engineering November 2022 27 more than 10 local sub-contractors from neighbouring townships were appointed. This job creation trend gradually increases during housing construction and further phases and will be sustained over an 8- to 10-year period and beyond as a result of further economic activities to be sparked by the complete development. ENGINEERING CONSIDERATIONS A large part of the project site area is situ- ated within environmentally sensitive and natural wetland areas. It was inevitable that some of the engineering services would encroach on these sensitive areas, and the designs allowed for optimum concentration of multi-services through these areas to minimise damage. Ekurhuleni Metropolitan Municipality has also indicated its requirement for attenuation facilities as part of the overall stormwater management requirements. Infraconsult Engineering has investigated various options of attenuation and has recommended that “instream” attenuation be done, utilising and upgrading old ex- isting farm irrigation dams and dam walls inside the Kliprivierspruit which flows north-south along the western boundary of the development. By making use of this innovative op- tion, the client will save millions of rands on the construction of lined, watertight attenuation dams across the entire devel- opment and will have more land available for residential and other purposes, thus optimising other advantages and benefits offered to the end user. Furthermore, it is a requirement in terms of the National Environmental Management Act and the National Water Act that no or minimal damage be done to the wetland areas inside the buffer and sensitive zones as a result of stormwater discharge. Infraconsult Engineering, in conjunc- tion with environmental specialists, came up with an innovative design concept of increasing (instead of decreasing) the number of stormwater discharge points in order to minimise localised damage at exit points, spreading the stormwater discharge points at various strategic points along the length of the stream, and introducing a combination of erosion pro- tection, silt catchment and control meas- ures with the use of gabion/reno mattress structures at the outlet structures.  The project targets the “missing gap” when it comes to housing beneficiaries Structural -Bridges - Foundations - Water Retaining Structures (Resevoirs, Water Tanks, etc.) - Residential Housing Developments -Commercial Developments - Taxi Ranks Municipal Infrastructure - Mega Cities - Roads & Stormwater - Water Supply - Sanitation Project Management Consulting OUR EXPERTISE Watervalspruit - Sky City Mega Housing Development, Alberton/Midvaal.
