The contract timeline includes the following explicit deadlines and phases:

• Individual Deadlines (Einzelfristen):
• Specific items identified as OZ: 00.01.0002, 01.01.0002, 02.01.0002, 03.01.0002, 04.01.0002, 05.01.0002, and 06.01.0002 must be completed no later than 36 working days after the contract award (Zuschlagserteilung).
• The handover of individual soil reports (Übergabe der einzelnen Bodengutachten) must occur no later than 48 working days after an unspecified event, likely the contract award.

Explicit contract start date, end date, and total duration are not stated in the provided documents, as these are left as placeholders to be filled in (e.g., "Spätestens (Datum)" or "Werktage nach Zuschlagserteilung") without specific values.

The core scope of work for this tender involves providing geotechnical reports (Baugrundgutachten) for several structures related to the "L116 Grevenbroich Ersatzneubauten Abs. 6" project (Project 48-1389-B) for Straßen.NRW - Regionalniederlassung Niederrhein.

The high-level summary of the Statement of Work and core deliverables includes:

Geotechnical Report Activities (Lph 1.1 - 2.3):

• Clarifying the task (Lph 1.1 Klären der Aufgabenstellung).
• Establishing the exploration program (Lph 1.2 Erkundungsprogramm festl.).
• Procuring existing documents/surveys (Lph 1.3 Beschaffen von Bestandsun..).
• Preparing and participating in relevant activities (Lph 1.4 Vorbereiten und Mitwirken..).
• Performing geotechnical calculations (Lph 1.6 Geotechnische Berechnungen).
• Evaluating ground explorations (Lph 2.1 Baugrunderkundungen ausw.).
• Estimating water levels (Lph 2.2 Wasserstände abschätzen).
• Classifying the ground (Lph 2.3 Baugrund klassifizieren).

Chemical Laboratory Tests (Chemische Laborversuche):

• Chemical analysis of soil (both < 32mm and > 32mm).
• Declaration analytics (Deklarationsanalytik).
• Chemical analysis according to BBodSchV (Chem. Unters. nach BBodSchV).
• Analysis of Polycyclic Aromatic Hydrocarbons (PAHs) according to EPA in solid material (Unters. PAK nach EPA im Feststoff).
• Analysis of phenol in eluate (Unters. Phenol im Eluat).
• Determining layer thicknesses (Schichtstärken bestimmen).
• Qualitative determination of tar content (qualit. Bestimmung des Teergehaltes).
• Assessment of concrete aggressiveness (Betonaggressivität).
• Assessment of steel aggressiveness (Stahlaggressivität).

BIM Methodology (BIM Methodik):

• Creation of a specialized ground model (Erstellung Fachmodell Boden), which is a three-dimensional volume model of layers and homogeneous areas for the entire section, incorporating exploration results from structural reports, covering an approximate surface area of 120,000 m².

The overall scope requires the contractor to perform all necessary and appropriate tasks to achieve the desired work success for the project.
