Development projects are usually launched with a well-established business plan. However, many developers consider archaeology as a force majeure whose impact cannot be anticipated, and one can only pray that its "damage" be minimal. Despite the many unknown factors faced when dealing with archaeology, it is definitely possible to predict future expenditures within reasonable margins of error.

The Kedem consulting team is capable of evaluating future expenditures due to the finding of antiquities during the preparatory proceedings of a real estate tender. Such an evaluation is achieved by studying the research and history of the site, and by constructing models based on adjacent areas with similar features. This procedure is applies when the site may include ancient or historical structures designated for conservation and reconstruction.
