Architektenleistungen nach Teil 3 Abschnitt 2 HOAI (Freianlagen)

The contract timeline includes the following explicitly stated information:

• Key Milestones/Phases:
• The completion of preliminary planning is scheduled for January 31, 2027.
• Further contract dates will be agreed upon with subsequent commissioning as per § 3 number 3.3.
• The project is divided into service phases, specifically mentioning Leistungsphase 1 through Leistungsphase 9.
• The execution of the construction project proceeds as a single overall measure up to service phase 4.
• Starting from service phase 5, the execution will be managed in two separate construction sections.
• A framework schedule, outlining the entire project with all processing and approval periods, including time-critical processes and important milestones, is to be created at the project start.
• During the planning phase, the schedule must be updated. It is recommended to develop a detailed schedule, including "planning of planning" and deadlines for awarding periods, by service phase 3.
• An award schedule must be prepared by the client after receiving the planning order, and by the contractor for the executing trades no later than service phase 6.
• In the execution phase, the schedule must be updated and monitored, including details for acceptance, defect management, commissioning, and handover to the user.
• Contractual deadlines are regulated in § 7 and are binding, though the client reserves the right to adjust or modify them, requiring the contractor's agreement and adaptation of their performance.

The contract start date, end date, and total duration are not explicitly stated.

The core scope of work for this tender involves architectural services for the "Hochschule Heilbronn, Gesamtsanierung E+F mit PV" project, specifically focusing on the open spaces (Freianlagen) and green roofs.

The key deliverables and statement of work summary cover the following Leistungsphasen (service phases) with specific tasks:

Leistungsphase 1: Grundlagenermittlung (Basic Evaluation)

• Clarifying the task based on client requirements.
• Site inspection and consultation on service and investigation needs.
• Advising on the planning method and formulating decision aids for selecting other planning participants.
• Summarizing, explaining, and documenting results.
• Special Services: Creating an existing model of the processing area, including connections to existing open spaces, trees, fire department access, terrain, art in construction, and paths/squares.

Leistungsphase 2: Vorplanung (Preliminary Design / Project and Planning Preparation)

• Analyzing fundamentals and coordinating services with other planning participants, including BIM-related aspects such as exchange information requirements (AIA) and participation in BIM execution plan (BAP) development.
• Coordinating target objectives and evaluating ecosystem interactions.
• Developing a planning concept, examining and evaluating variants considering topography, ecological conditions, environmental concerns (nature and species protection), and design/functional requirements.
• Presenting the preliminary design in a digital model with explanations and timeline.
• Cost estimation according to DIN 276 - 1: 2018-12 and comparison with financial constraints.
• Summarizing, explaining, and documenting preliminary planning results.
• Special Services: Assessing and evaluating existing artistic installations ("Kunst am Bau") for integration and protection, and evaluating existing vegetation for preservation and protection during construction.

Leistungsphase 3: Entwurfsplanung (Design Planning / System and Integration Planning)

• Developing the detailed design based on the preliminary planning.

BIM-Related Tasks (across relevant phases):

• Structured collaboration and creation of all necessary partial and specialized models with specified information depth.
• Conversion of models to IFC format, self-checking for conformity, and submission to BIM overall coordination.
• Merging specialized and partial models into a coordination model, performing quality checks with a model checker against specifications (AIA, LOIN, BAP).
• Model-based identification and resolution of conflicts (taboo and exclusion zones), including documentation (BCF files) and coordination meetings.
• Modeling recesses, niches, breakthroughs, and slots (model-based slot and breakthrough planning).
• Generating quality reports on processing status and planning progress.
• Utilizing models for planning progress control and quality assurance through regular comparison with requirements.
• Plan documentation at the end of Leistungsphase 2, 3, 4, 5, and 8.
• Rule-based derivation of quantities, elemental determination of masses and quantities from BIM models for cost estimation and plausibility checks.
• Planning and communication of logistics processes (construction site setup, infrastructure, traffic, storage, delivery zones, machine movements) using specialist models.
• Regular comparison of planned (As-Planned) with actual construction progress (Ist-Zustand) using scans for object monitoring and documenting execution, ensuring compliance with timelines and quality.
