COVER STORY:Koch Hightex, the German firm now taking legal action against the New Millennium Experience Company over cancellation of its contract to clad the Greenwich Dome, is busy on the prestigious £9M job to replace the 26 year old transparent acrylic covering at Munich's Olympic Park. The cable net structure was conceived as a spectacular translucent spider's web to cover to the stadium, swimming pool and Olympic hall of the 1972 Games but had weathered to an ugly mixed patchwork of opaque and clear panels. Recladding and replacement of corrosion protection on the cable structure has to be finished on the stadium itself by July ready for a concert in huge amphitheatre. The steeply sloping roof is now crowded with operatives stripping and replacing the aluminium-framed panels and the rubber seals in between. Safety nets rather than harnesses are being used to catch any who slip.
