TECHNICAL TASK (TT)For the design and calculation of a large frame aquarium structure1. GENERAL INFORMATION AND PURPOSE Product type: Large demonstration frame-type aquarium. Purpose: Public/private interior aquarium for keeping hydrobionts. Objective: Development of design documentation (DD) for the manufacture of a metal frame, selection and calculation of the thickness of multilayer glazing (triplex), design of the base with waterproofing nodes, as well as calculation of elements for transportation by forklift.2. GEOMETRIC AND WEIGHT PARAMETERS External dimensions of the structure (L×W×H): 4000 × 1800 × 1400 mm. Height of the water column (maximum): To be structurally accepted as equal to 1300 mm (taking into account technological underfilling). Configuration: Rectangular basin with a 360° view (all 4 vertical sides — transparent glazing). Weight limitation (dry weight): The maximum weight of the fully assembled finished product (metal frame + installed glazing + bottom elements) must not exceed 3000 kg (3 tons). This is a critically important condition for ensuring logistics and the lifting capacity of rigging equipment.3. TECHNICAL REQUIREMENTS FOR CONSTRUCTIVE ELEMENTS3.1. Metal Frame (Structure) Type of construction: Spatial welded frame made of steel profile with a continuous perimeter fixation for each glass. Each of the 4 glasses is a separate panel glued into the quarter (groove) of the metal frame on 4 sides. Stiffness: The structure must have maximum stiffness against bending and twisting. The deflection of load-bearing elements under full static load must not exceed permissible values to avoid the occurrence of peak local stresses in the glass and adhesive joints. Supports: Provide supports for precise leveling and even weight distribution on the foundation/base. They may be non-adjustable.3.2. Glazing (Vertical Walls) Material: Multilayer laminated glass (triplex) based on tempered or float glass of increased transparency (type Optiwhite). Optiwhite Perform strength calculations for hydrostatic pressure. Determine the final safe formula for triplex (layer thickness and type of polymer film — PVB / SentryGlas), ensuring minimal weight with required strength. SentryGlas Calculate the depth of glass embedding in the frame and parameters of the deformation adhesive joint.3.3. Bottom of the Aquarium and Transport Nodes Base construction: Rigid frame base of the metal structure, covered with moisture-resistant sheet material (moisture-resistant plywood/composite). Bottom waterproofing: Finish coating with specialized PVC membrane ("pool foil"). Forklift clearance: The lower beam of the frame must have a structural clearance from the floor of at least 100–120 mm for unobstructed entry of forks. Pockets for the forklift: Design through guide pockets (slots) in the structure of the pallet for standard dimensions of heavy forklift forks. The pockets must pass through the entire frame for the possibility of lifting the product from either of the two long sides (4000 mm).4. CALCULATIONS AND LOADS (MANDATORY PART) The designer must provide verified calculations (including finite element method — FEM / FEA) on the following points: Hydrostatic load: Calculation of the pressure of the water column up to 1300 mm on the vertical walls and bottom (total water volume about 10,000 liters, operational weight ~10 tons). Glass strength calculation: For bending and strength considering the safety factor for frame-type aquarium constructions (not less than 3.0–4.0). Metal frame calculation: Static calculation of the filled aquarium for stiffness and deflection. Adhesive joint calculation: Selection of parameters and thickness of structural silicone/polyurethane for shear and pull-off under water pressure. Weight audit and optimization: If the total dry weight of the metal frame and calculated triplex exceeds 3 tons, measures must be taken to lighten the structure (use of high-strength steel grades with reduced profile cross-section, optimization of triplex structure, use of lightweight composites for the rough bottom).5. REQUIREMENTS FOR THE DOCUMENTATION TO BE ISSUED (DD) After the design is completed, the contractor provides: An explanatory note with calculations of the strength of the frame, glazing, and rigging nodes. Assembly drawings of the metal frame (marks KM/KMD) with a specification of metal products. Drawings of details and cutting maps of bottom elements. Detailed drawings of connection nodes: "glass — metal" "glass — damper — adhesive" "sealing of the joint PVC membrane bottom — glass — frame" "pockets for the forklift" A specification of all materials (steel grade, exact triplex formula). A 3D model of the product in a neutral format.

Order: 3D Modeling of Facade Cladding and Parapets Based on Point Cloud (BIM / CAD) I am looking for an experienced designer / 3D modeler who will create an accurate geometric model of the facade cladding and roof/parapet area based on the provided point cloud (laser scanning).Scope of the order: Extraction from the point cloud and precise reproduction of the geometry of the external walls. Creation of a 3D model of the facade cladding (steel substructure visible in the attached photos).

Photographic documentation of details.Requirements: Fluent knowledge of software for working with point clouds and modeling (e.g., Revit, Rhino, SolidWorks, AutoCAD or related). Experience in designing ventilated facades, steel/aluminum structures, or sheet metal work. High accuracy (working in millimeters) and understanding of building geometry.Conditions: Work format: Remote. Output file format: To be agreed upon (e.g., DWG 3D, STEP, IFC, RVT). Compensation and deadline: To be determined individually based on the complexity of the object.

Location: Lubin Object type: Aquapark Scope of work: I am looking for an experienced company or freelancer to perform comprehensive 3D laser scanning of the building. The assignment includes: Performing ground scans outside the building. Registering and stitching scans into one coherent point cloud. Cleaning the cloud from noise and moving objects.Expected output files: Registered point cloud in the format: e57 format must be compatible with SolidEdge software. Photographic documentation from the scanner positions (spherical panoramas). [Optional] Simplified mesh or preliminary solid model - to be agreed upon.Requirements for the contractor: Possession of own professional equipment (3D laser scanner, e.g., Faro, Leica, Trimble). Experience in executing similar assignments. Accuracy and timeliness.Settlement: Settlement method to be agreed upon (VAT invoice / contract for work). Please provide an estimated price for the entire assignment. Attached are photos of the building and substructure that will be scanned.

According to the completed project for the separation of floors, it is necessary to develop detailed drawings in KMD for manufacturing at the factory. The project is available in PDF and DWG.

There is a preliminary concept for the lifting mechanism of a compact product. Since I am not a design engineer, I cannot assess how optimal the chosen scheme is. It is necessary to: evaluate the proposed concept; if it is viable — refine it; if there is a better solution — propose an alternative option with an explanation of the advantages. Main requirements: compact placement of the mechanism inside the product; synchronous lifting of the lid; possibility of using an electric drive; high reliability; minimal number of parts; preferably, the mechanism should be visually open and look aesthetically pleasing. (brass gears, rack and pinion) I found the most suitable mechanisms and principles for lifting the lid on Pinterest. But I do not have the skills to adapt it to my design. https://www.instagram.com/reel/C5gc3snolm1/?utm_source=ig_web_button_share_sheet In my case, the gears are brass and the pinion lever is thin.
