The core scope of work for this tender involves structural engineering services ("Leistungen der Tragwerksplanung") for the expansion of the OGTS Schönau Elementary School ("Erweiterung OGTS Grundschule Schönau"), encompassing service phases 1 through 6 and 8, as per § 49 ff HOAI.

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

Service Phase 1 (Grundlagenermittlung - Basic Appraisal):

• Summarizing, explaining, and documenting the results of this phase to provide a comprehensive overview of the project's foundations.
• Providing a detailed explanation of the basic appraisal results.

Service Phase 2 (Vorplanung - Preliminary Design / Project and Planning Preparation):

• Assisting in developing the core planning concept and roughly estimating overall costs.
• Analyzing and organizing the project's foundational data from Phase 1 and client specifications, coordinating services with other specialized planners.
• Providing static-constructive advice to the object planner and client, focusing on structural safety, usability, and economic efficiency.
• Contributing to the planning concept, including exploring structural options with sketches and defining key constructive elements like materials, construction types, structural grids, and foundation methods.
• Supporting preliminary negotiations for regulatory approval with relevant authorities, the reviewing engineer, and specialists (e.g., technical equipment, foundation, thermal insulation, energy balance, acoustics).
• Assisting in cost estimation according to DIN 276-1:2008-12 and creating a project schedule.
• Summarizing, explaining, and documenting the results of this phase in a clear, written report that details all significant project influences.

Service Phase 3 (Entwurfsplanung - Design Planning / System and Integration Planning):

• Developing an approval-ready, structurally sound, and economically viable structural solution.
• Creating the structural solution, incorporating specialist planning from the object design, leading to a constructive design with drawings. This includes detailing load-bearing cross-sections, statistically significant openings, support points, joints, and connection methods.
• Performing approximate static calculations and dimensioning.
• Defining fundamental constructive details and main dimensions of structural elements (e.g., grid, dimensions of columns, walls, ceilings, beams, and specific structural features).
• Roughly estimating material quantities such as rebar, steel, and timber.
• Contributing to the object description by detailing structural aspects, including essential constructive specifications and impacts on construction costs, as well as comprehensive descriptions of elements not evident in plans but crucial for cost assessment (e.g., construction processes, foundation methods, specific structural properties like crack safety, watertightness, fire resistance).
• Assisting in negotiations with authorities and other involved parties regarding approval.
• Supporting cost calculation according to DIN 276-1:2008-12, contributing to scheduling, and assisting in cost control by comparing calculations with estimates and proposing corrective actions.
• Summarizing, explaining, and documenting the results of this phase.

Service Phase 4 (Genehmigungsplanung - Approval Planning):

• Preparing verifiable static calculations for the structure, adhering to specified building physics requirements and state building regulations.
• For engineering structures, documenting standard construction states.
• Producing position plans for the structure or integrating all static positions relevant to the stability certificate.
