Competitive procedure for residential development "Heiligkreuz-Viertel"
In the course of the Heiligkreuz Quarter project, the property owners have committed themselves to ensuring the urban design of the new city quarter by undergoing quality assurance procedures when planning the individual construction sites. For some construction sites, competing procedures (e.g., competitions) are being held, which are being organized by the respective developers. The procedures that have already been carried out and their results are presented below.

Planning process
On the more than 30-hectare site of the former IBM production facility in Mainz Weisenau, the city of Mainz is developing a new mixed-use urban quarter with a variety of housing options, good infrastructure, and an attractive living environment.
In 1965, IBM Germany's Mainz branch began operations on the site. Due to global cooperation agreements, IBM discontinued hard disk production at the Mainz site at the end of 2003 and closed this production facility.
Following the extensive abandonment of previous commercial uses, the entire site offers opportunities for restructuring.
In October 2014, the city of Mainz adopted an urban development framework plan for the former IBM site and adjacent areas to qualify a new utilization concept. Based on an analysis of the existing situation, this framework plan defines the new basic usage structure and typology, the basic development and important green connections, as well as essential links to adjacent neighborhoods.
The framework plan formed the basis for a two-phase urban development competition, which was announced by the property owners in spring 2015. In this process, a jury selected the design by the firms Hermann&Valentiny and Latz+Partner as the winner from 22 submitted entries on June 26, 2015.
This urban design formed the basis for the development of the urban development plan. With its publication in the Amtsblatt, the "Heiligkreuz-Areal (W 104)" development plan came into legal force on November 17, 2017.
Parallel to the development plan, a design manual was drawn up to guide the subsequent implementation of the individual properties in terms of urban design.
The first development work within the planning area began in 2017. The first construction project to be implemented is the new local shopping center in the northwest of the planning area.
