A method and apparatus for establishing a wire network for a platform. The apparatus for establishing a wire network for an aircraft comprises a wire manager and a layout manager. The wire manager sorts a plurality of wires for the aircraft into a plurality of bundles based on a plurality of categories established for the plurality of wires with respect to operation of the aircraft. The plurality of categories includes an essential category and the plurality of bundles includes a primary bundle corresponding to the essential category. The layout manager generates a primary layout output for the primary bundle based on an available space within the aircraft. Forming and installing a primary wire harness corresponding to the primary bundle in the aircraft based on the primary layout output independently of a remaining portion of the plurality of bundles improves a build efficiency of the aircraft.
