Hauptstudie DiGeVe - Datenerhebung & Auswertung

The contract start date is "immediately after contract conclusion". The latest specified milestone completion date is February 28, 2029, marking the end of the second run's data preparation, statistical evaluation, and special evaluation of settlement-structural region types. The total duration therefore extends from the contract conclusion to February 28, 2029.

Key milestones and phases are structured in two runs:

First Run (1. Durchlauf):

• Development of survey design (questionnaire design, survey method, questionnaire programming): October–December 2026, with Milestone 1.1 by December 31, 2026.
• Operational execution of data collection ("completed field phase" with sample size and sampling for CAPI and CAWI versions): January–February 2027, with Milestone 1.2 by February 28, 2027.
• Data preparation and statistical evaluation: March–April 2027, with Milestone 1.3 by April 30, 2027.
• Special evaluation of settlement-structural region types: March–April 2027, with Milestone 1.4 by April 30, 2027.

Second Run (2. Durchlauf):

• Development of survey design (questionnaire design, survey method, questionnaire programming): August–September 2028, with Milestone 2.1 by September 30, 2028.
• Operational execution of data collection ("completed field phase" with sample size and sampling for CAPI and CAWI versions): October–November 2028, with Milestone 2.2 by November 30, 2028.
• Data preparation and statistical evaluation: December 2028–February 2029, with Milestone 2.3 by February 28, 2029.
• Special evaluation of settlement-structural region types: January–February 2029, with Milestone 2.4 by February 28, 2029.

Additional relevant dates from the procurement process include:

• Deadline for questions on tender documents: September 18, 2026, 12:00 AM.
• Offer deadline: September 25, 2026, 12:00 PM.
• Provisional award: October 26, 2026.
• Binding period for offers: Until December 31, 2026.

The core scope of work for this tender involves conducting two large-scale quantitative primary surveys, including the development and programming of the survey design, such as questionnaire design and selection of survey methods. This also includes the operative execution of data collection, encompassing sample drawing, field control, weighting, and the delivery of a quality-assured raw dataset. Additionally, the scope covers data preparation and statistical evaluation, designing and performing complex statistical analyses in two separate runs, and a special analysis of settlement-structural region types, also in two runs. Project management tasks, such as preparing and conducting a kick-off meeting, and providing weekly progress reports and being available for coordination meetings, are also part of the scope.

The core deliverables, categorized as "Werk „Studie DiGeVe im Durchlauf 1“", "Werk „Studie DiGeVe im Durchlauf 2“", and "Werk „Regionale Schwerpunktbetrachtung“", are as follows:

For each of the two runs:

• Finalized and approved questionnaires for both CAWI and CAPI versions, along with a pretest report.
• A field report that includes documentation of field control and a comparison of actual versus target quotas.
• A complete, quality-assured dataset in SPSS and Excel formats, weighting documentation, a results table band (including basic counts and subgroup evaluations), and a commented methods report (codebook).

For the "Regionale Schwerpunktbetrachtung":

• A focus analysis on the regional dimension and prepared data tables categorized by region types.

The overall purpose is the execution, evaluation, and documentation of two population-representative surveys for the "Die digitale Gesellschaft – verstehen, gestalten, stärken. Mechanismen, Hebel und Gelingensbedingungen digitaler Transformation (DiGeVe)" project, leading to two publications in 2027 and 2029.
