This document provides an update to the Technical Design Report for the Electromagnetic Calorimeter of the PANDA Experiment. The original TDR was published in August 2008 (RE-TDR-2008-001). The document was sent to the ECE. The answers to their questions are given in the second document.

This document presents the technical layout and the cost assessment for the infrastructure of the PANDA experiment, comprising the following major items: - Supports: Mechanical structures to support the experimental setup, fixed and removable platforms to house equipment and to assemble the experiment, including staircases, ladders,fences, racks and related tools. - Supplies: Distribution systems for electrical power, grounding, fluids and gases. Based on this, the current integration planning and the installation procedure are described. UPDATE July 3: Updated version v1.0 submitted to external referees. UPDATE August 28: Updated version v2.0 for inspection by the PANDA CB before submission to ECE. UPDATE September 14: Version v3.0 for submission to FAIR ECE. Bibliographies completed.
