ESA manufactures its hollow-core slabs using state-of-the-art technology. It also has the R&D support of Elematic in Finland, which has a solid reputation based on five decades of experience. The benefits of using Elematic slabs include the fact that the prefabrication process under controlled conditions assures clients of consistent quality; the fact that the slabs can be installed quickly on site without the need for back-propping or curing time; and the fact that they typically require very little finishing once installed.
October marked the beginning of a new chapter in the history of the Institution. The formerly known SAICE Wits Branch was revamped and renamed the SAICE Johannesburg Branch. With the name change comes a change in governance - the committee of the new Johannesburg Branch consists entirely of young graduates. The decision was made to directly involve young engineers in the governance of the Branch so as to attract fresh ideas and to provide a platform for SAICE's younger Johannesburg members to meet the needs of their fellow young bloods. The plan envisaged was to involve more young people in the leadership of SAICE and to allow them the opportunity to participate in carving the future of the Institution.
SAICE's magazine, Civil Engineering, won the prestigious PiCA Award for the third year running on Thursday evening 26 November at a gala event held in Johannesburg.

Municipal solid wastes are currently receiving attention as potential minor sources of energy. Wastes can make a contribution of the overall energy situation in four ways: directly, by combustion of wastes to produce energy; indirectly, by conversion to gaseous liquid or solid fuels; by returning to the economy materials manufactured by energy intensive processes; and by providing a feedstock for the manufacture of materials normally produced from key energy resources such as oil.
