The renovation work performed by Merko Infra in the existing areas in the Tallegg complex encompassed 1,800 m² while the construction of the addition added 5,000 m² of space. The renovation of part of the Tabasalu plant and construction of the addition were rendered complicated in the construction sense by the fact that the existing complex continued to operate throughout the construction process. Thus the renovation of the various parts of the existing production building and the construction of the new factory building had to be carefully thought through and planned in the sense of production and construction as a whole so that both could go off without a hitch.
