Measurements of the soil water balance (Award No.: 72-Z1157/26, IntraPlan No.: 240090)

Regarding what the bidder must submit and the minimum qualification, the input specifies, such as in the “Aufforderung zur Abgabe eines Angebots”, that bids must be lodged electronically via the AI‑Vergabemanager, with a detailed price calculation using Anlage 2 (Kalkulation nach Personenstunden, Stundensätze, Festpreis inkl. Nebenkosten, Netto‑Preis plus USt‑Satz). With the offer, bidders must submit: (i) the form “01‑1 Eigenerklärung” (including statements on taxes, social contributions, MiLoG, BG insurance, exclusion grounds under §§ 123, 124 GWB, use of subcontractors, signature requirement), (ii) the form “01‑2 Eigenerklärung EU‑Grundrechtecharta_AN” including a list of project participants and an acknowledgment of EU Charter/UN‑BRK compliance, (iii) the form “01‑3 Informationsblatt Sanktionen Russland – Eigenerklärung” (Art. 5k VO (EU) 833/2014, no Russian links >50 %, no Russian‑related subcontractors >10 % of contract value), and (iv) if relevant, the “Erklärung Bietergemeinschaft” (joint and several liability, named representative) and the “Einsatz Unterauftragnehmer” form (listing subcontractors and their tasks). For technical and professional capacity, bidders must provide at least five suitable references from the last five years with a main focus on soil‑water budget measurements (esp. infiltration) and evaluation of physical/chemical soil parameters, plus proof that the responsible project lead holds a relevant university degree (geosciences, environmental analytics, geoecology, hydrology, agricultural/forest sciences or equivalent) and that staff has good knowledge of soil physics, ecohydrology, and crop production; communication and reporting in German at level C1 is required.

As to the scope of the contract (what, where, when), the Leistungsbeschreibung outlines, such as, measurements of the soil water budget in the JTF project area “Wasserrückhalt in der Fläche” with specific standorte in the Löbauer‑Wasser catchment (see Anlage 1). There are repeated measurement campaigns per site (Kapitel 6.3 Wiederholung pro Standort) at defined times related to crop sowing and development; exact measurement dates are agreed ad hoc between AG and AN depending on crop stand, weather and the consent of third parties. The deliverables include field measurements (infiltration etc.), data analysis, a written Zwischenbericht (first measurement series after main crop sowing) and a Abschlussbericht (all series, all times, including description of trial procedures per scenario/location, photo documentation, error analysis) plus tabular data in Excel format. The contract period runs from award until 31.12.2027, with the final report and measurement results due by 30.11.2027; additional specified meetings (anlaufberatungen with AG and project farmers for different sowing systems, consultations on interim results and optional additional measurements, two extra consultations) must be costed separately and may take place in Dresden, Freiberg, Nossen or on farms; some consultations can be held via videoconference.

Concerning award criteria and weighting, the texts state, such as in “Grundlage Punktebewertung”, that the economically most advantageous tender is chosen on the basis of 30 % price and 70 % quality. Price receives up to 30 points, with 30 points for the lowest evaluated price, 0 points for prices at or above twice that level, and linear interpolation in between according to a given formula. Quality receives up to 70 points split into four sub‑criteria: (2.1) structure and approach (max. 30 points) – clarity, plausibility, timely implementation, flexibility for delays; (2.2) use of adequate and appropriate methods (max. 20 points) – explanation and justification of methods, and methodical deepening of the LB approach; (2.3) comprehensibility of technical solution proposals and practical implementability of field work (max. 15 points), including proposals for optional extra measurements; and (2.4) consideration of regional characteristics (max. 5 points) – addressing landscape diversity and agricultural specifics in the study area. The rating table sets bands for “sehr gut” down to “unzureichend” for each sub‑criterion. In case of a tie in total points on rank 1, the cheaper tender wins.

Risks and special conditions are covered, such as in the ZVB‑related clauses and LB section 12: the contract is a Werkvertrag; the LfULG’s ZVB (version 12/2025) and VOL/B become integral parts unless overridden by the LB. Payment follows verified partial performance via Abschlagsrechnungen for completed work packages, to be invoiced by 15.10 of each financial year with a bidder‑submitted Zahlungsplan. The payment period is set to 35 days (deviating from ZVB 14.1) but may be extended by a reasonable time due to funding compliance checks; the contractor will be informed of delays. If the contractor is a public‑law institution, contractual penalties in ZVB section 16 do not apply. Subcontracting carries risk in that the bidder acknowledges exclusion if a named subcontractor is itself excluded; planned subcontractors and the scope of their work must be disclosed, and, where their capacities are used for qualification (Eignungsleihe), a binding commitment must accompany the bid. The bid’s validity (Bindefrist) runs until 22.01.2027, offers must be signed (otherwise deemed not submitted), and side‑offers (Nebenangebote) are not allowed. Questions or clarifications must be submitted exclusively via the AI‑Vergabeplattform (Bietercockpit) to the named contact; no mention is made of an explicit question deadline, so general VgV practice applies. A specific site visit is not described; instead, coordination with farms and third parties is foreseen under the AG’s services.

On contradictions or corrections, the documents are largely consistent: dates for Angebotsfrist (05.11.2026), Bindefrist (22.01.2027), and Ausführungsfrist/Liefertermin (31.12.2027) repeat identically in the Aufforderung, Eigenerklärung and LB. Where differences appear between ZVB and LB, the LB expressly states that its deviations prevail (e.g. modified payment deadline); this establishes the rule that the LB takes precedence over the standard conditions where explicit changes are written. The EU‑sanctions text and minimum‑wage/exclusion provisions are repeated across forms but in identical substance, so the version in the specific Eigenerklärung forms is controlling for the bidder’s obligations. Where the documents list items that “verbleiben beim Bieter und müssen nicht mit dem Angebot übersandt werden” (e.g. ZVB, Datenschutzinformation, BBL, Aufforderung, Punktebewertung), this clarifies that these are for information only; the binding submission set is defined in the Aufforderung (price calculation, method description, time and payment plans, mandatory forms and reference list).
