This document outlines the cost estimates and schedule for the Forward Vertex Detector (FVTX), detailing major mechanical, electrical, and construction activities. Based on historical experience with VTX and ATLAS sensors, the cost projections from various vendors, such as HYTEC and PROMEX, are highlighted alongside the planned R&D timelines. Key assumptions include construction starting in January 2008 and specific efficiency rates for component testing. The total project cost is analyzed with contingencies, ensuring a thorough understanding of the funding profile and resource allocation.
