STAGE I – PRE-DESIGN ANALYSES AND MASTERPLAN In this stage together with the Investor we analyse functional assumption and main purpose of the investment. Then, we check locational and legal requirement and based on it, we create a map of the risk and show the investor opportunity to avoid it. After that, we propose schedule of the work: obtaining an administrative decision, specialist opinion and permit and we verify the budget. The key point in this stage is to give an answer at the arises question: If is it possible to realize the investment in the defined date and in given budget? Important part of the analysis is the functional inventory of the building based on materials given by the Investor and in-site measurement. As a result we receive simplified layout showing existing condition of the building. This document shows precisely functional problems as mixing communication ways, wrong functional connections but also good solutions that should be preserved.
