Planning of the premises and the project of the facility

Hello! I am looking for a structural engineer or an experienced 3D designer to create a preliminary 3D model of a construction fastener (a universal flat spacer for securing cables in a groove).At this stage, I need a quality sketch concept (visualization) and basic drawing for evaluation by lawyers. The project will be further developed for the production of a mold (TPA).What needs to be designed: A flat elastic plate (fastener) with the following input data: Product dimensions: Maximum length — 62 mm, maximum width (including teeth) — 40 mm. The base thickness of the plate is about 2.5–3.0 mm. Side edges: Equipped with locking teeth inclined backward (harpoon principle). The spacing between the teeth should be uneven/variable. Central part: A through cylindrical hole with a diameter of 4.2 mm. The front side must have a conical countersink (recess) so that the screw head is hidden inside the plastic. Surrounding the hole, there should be a slight thickening (stiffening rib) to prevent the part from cracking under pressure. Top end: A flat platform for finger pressure with a fine anti-slip texture.What is required as output: A solid 3D model of the part in .STEP or .IGES format. A simple engineering drawing (sketch of the overall view) in .PDF format, considering dimensions and annotations of elements. 2-3 quality renders (isometric, side view) on a clean white background for the patent application.Important requirement: The performer must understand the specifics of plastic injection molding (TPA) and immediately incorporate basic casting drafts (0.5–1.5 degrees) into the concept so that the part is suitable for future production.Please indicate your price for this initial stage and realistic deadlines for completion. I look forward to your responses!

I am looking for a designer to prepare working drawings for exhibition stands. I need a person with experience working with composite materials, who understands their capabilities and limitations, and knows how to properly design parts for milling and production. The task is to create technical drawings, including visualizations: assemblies, sections, dimensions, fastenings, specifications, and other data necessary for the construction manufacturing. It is preferable that the candidate already has experience in exhibition stands, advertising, or decorative constructions and can offer practical, technological solutions for production. Here are some examples of the direction to move in: https://www.instagram.com/market_tablo https://www.instagram.com/crealle/ https://www.instagram.com/artefinal_brasil/ https://www.instagram.com/rahbardesign/ https://www.instagram.com/kiancogroup.cnc/ Attached photos also include samples. In the PDF - the design that needs to be tested currently. It is not guaranteed that this project will be confirmed and go into production, but I need to understand the designer's approach. In any case, the test will be paid. The working area of the milling machine is 2100*4100 (vacuum table and automatic tool change with 7 positions).

A set of documentation is required to perform construction and installation works without the contractor independently making design decisions regarding: planning; height; foundations; retaining walls; entrance group; openings; embedded; engineering network passages; drainage. Based on the ENZ in .DWG format, topographic survey, and general plan. The task is to create an author's planning and height solution so that builders receive a clear set of drawings for earthworks, foundation, and monolithic works that form the basement, retaining walls, entrance group, and surface drainage systems. The work does not include the design of the metal frame of the canopy, the roof of the canopy, and KM/KMD — embedded parts, reinforced belts, etc. Heights, dimensions, and locations of their placement need to be shown. Separate complete engineering sections for HVAC, plumbing, and electrical systems are also not included, but the locations of passages and connections for these networks, channels, and technical openings need to be shown. A set of DWG + PDF is needed, sufficient for performing the work without additional solutions on the construction site. Important: the technical task (TT) is the main document that defines the subject, scope, requirements, and conditions for performing the work. All agreements, criteria for evaluating the result, scope of work, and resolution of disputed issues are carried out based on the approved TT.

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.
