The core scope of work for this tender involves Object Planning for Freianlagen (Outdoor Facilities), encompassing all services from Leistungsphase 1 to 9 according to § 38 ff. HOAI (German Fee Schedule for Architects and Engineers) and § 39 Abs. 3 HOAI in conjunction with Anlage 11.1. The project specifically concerns the energetic renovation of a sports hall, including the examination of its conversion into an assembly venue, and the renewal of the outdoor sports facilities at the Albert-Einstein-School in Rösrath.

The services are to be rendered in two stages:

Stage 1 includes:

• Leistungsphase 1: Grundlagenermittlung (Basic Evaluation)
• Leistungsphase 2: Vorplanung (Preliminary Planning)
• Analyzing fundamentals and coordinating services.
• Coordinating objectives and identifying conflicts.
• Recording, evaluating, and explaining ecosystem interactions.
• Developing a planning concept, including examining and evaluating variants, considering topographical, ecological, environmental, and design requirements.
• Presenting the preliminary design with explanations and a timeline.
• Cost estimation and comparison with financial frameworks, including justifying deviations and proposing control measures.
• Summarizing, explaining, and documenting the results.
• Leistungsphase 3: Entwurfsplanung (Draft Planning/System and Integration Planning)
• Developing a technically and economically sound and approvable design.

• Creating plans or descriptions, e.g., at a scale of 1:200 to 1:50.
• Coordinating and integrating contributions from other involved planners.
• Presenting outdoor facilities with necessary information, detailed or construction drawings, including surface materials, installations, vegetation, and landscape conservation measures.
• Updating the schedule.
• Updating the execution planning during object execution.
• Leistungsphase 6: Vorbereitung der Vergabe (Preparation for Award)
• Preparing service descriptions with bills of quantities, adhering to VOB/A and ATV VOB/C guidelines.
• Determining and compiling quantities based on execution planning.
• Coordinating service descriptions with other involved planners.
• Preparing a schedule considering seasonal, construction, and weather-related requirements.
• Determining costs based on priced bills of quantities.
• Cost control by comparing priced bills of quantities with the cost calculation.
• Compiling tender documents.
• Leistungsphase 7: Mitwirkung bei der Vergabe (Assistance in Awarding)
• Obtaining offers.
• Reviewing and evaluating offers, including creating a price comparison.
• Conducting discussions with bidders to clarify offer content.
• Preparing award proposals and award notices.
• Compiling contract documents.
• Cost control by comparing tender results with priced bills of quantities and cost calculations.
• Assisting in contract award.
• Leistungsphase 8: Objektüberwachung (Bauüberwachung) und Dokumentation (Object Supervision and Documentation)
• Monitoring object execution for compliance with approvals, contracts, execution documents, regulations, and recognized technical standards.
• Checking plant and material deliveries.
• Coordinating with other technically involved parties in object supervision.
• Updating and monitoring the schedule.
• Documenting the construction process (e.g., construction log), assessing growth results.
• Assisting in measurements with construction companies.
• Invoice verification, including checking measurements of executing companies.
• Comparing invoice verification results with contract sums, including amendments.
• Organizing acceptance of construction services.
• Applying for and participating in public law acceptances.
• Handover of the object.
• Monitoring rectification of defects found during acceptance.
• Listing limitation periods for defect claims.
• Monitoring completion care for vegetation-technical measures.
• Cost control by verifying performance invoicing of construction companies.
• Cost determination, e.g., according to DIN 276.
• Systematic compilation of documentation, drawings, and calculated results.
• Leistungsphase 9: Objektbetreuung (Object Support)
• Technical evaluation of defects identified within the warranty periods, up to five years after acceptance, including necessary inspections.
• Object inspection for defect detection before the expiry of limitation periods against executing companies.
• Assisting in the release of collateral.

The commissioning of "Besondere Leistungen" (Special Services) is optional and will occur with the respective stage call-off. Examples of special services mentioned include: evaluating existing building substance, materials, installations, or protected vegetation; technical assistance in applying for and settling funding; and creating a flood certificate for properties.

The overall project aims to ensure that planning and realization proceed according to defined deadlines, with the contractor responsible for timely commencement, execution, and completion of services. Cooperation with other specialized planners (e.g., object planning, TGA and electrical planning, fire protection engineers) is a prerequisite for successful construction. The coordination of involved specialized planners lies with the object planner. The HOAI 2021 serves as the basis for the service description and fee remuneration.
