Assembly Principle: Completely weld-free, exclusively using bolted connections (“NO-WELD BOLTED CONSTRUCTION”). The structure is modular (Flat-Pack) to minimize logistics costs and facilitate self-assembly by the customer. 1. TECHNICAL REQUIREMENTS AND AESTHETICS • Requirement for the developer: The product must be designed to have a flawless, presentable commercial appearance for export to the EU market. • Intuitive assembly: The design should allow for the simplest assembly possible, enabling the customer to assemble the box independently without special tools. • Frame material: Stainless steel AISI 304 (matte), sheet thickness — 1 mm. • Construction: Corner system with flanging for rigidity and safety. Stacking (nesting) during transportation. • Wall filling (sandwich): PIR board (30 mm) with a tolerance of ±4 mm. The groove design should compensate for this tolerance, eliminating gaps. • Wall cladding: PIR board is covered on both sides with smooth stainless steel sheets of 0.5–0.6 mm. • Assembly: Strictly with bolts (stainless steel A2/A4). Minimum number of bolted connections inside the working area for ease of cleaning and disinfection. • Feet: Height 30 mm, integrated into the lower binding contour. 2. DOOR CONSTRUCTION AND LOCKING • Sealing: Rubber seal around the entire perimeter of the reveal and a stop (false bar) for 100% elimination of gaps. • Hinges: Seat design that eliminates play (bolts serve only the function of clamping). • Locking: Mechanical latch lock “finger in hole”. • Door configuration: Doors spanning the full width and height of the facade, divided horizontally into two independent sections: upper and lower. ◦ Lower section: blind. ◦ Upper section: has a viewing window. ◦ Operating principle: The lower section opens first and, when closing, tightly presses against the upper section. • Viewing window (Product No. 1): Located in the upper section. Double-sided, with an air layer. Clamping strips for securing any transparent material (glass, plastic, or film) with a thickness of from 2 to 5 mm. 3. VENTILATION SYSTEMS (Identical for both products) • Protection: Mesh (stainless steel, wire 0.5 mm, cell 0.8 mm). Installation — through clamping frames with bolts (without drilling the mesh). • Upper exhaust (120 cooler): Cutout 200x200 mm in the roof, cooler installation through a flange with M4 thread. Under the cooler (above the mesh) — adjustable damper (shutter). • Lower intake: Two openings (left and right), raised 100 mm from the floor. Area of each — 300 cm². Both intakes have adjustable dampers (shutters). 4. PRODUCT SPECIFICATION • PRODUCT No. 1 (Vertical 600x600x1200 mm): Two-section doors (lower blind, upper with window). Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), curtains for mesh suspension, strip for the shield from the end. • PRODUCT No. 2 (Horizontal cabinet 600x600x600 mm): Single-section doors without glazing. Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), stainless steel guides for shelves, strip for the shield from the end. 5. WHAT IS REQUIRED TO BE DELIVERED: 1. 3D assembly: STEP / SolidWorks formats, with the ability to freely disassemble the model. 2. Drawings: Detailed drawings of assembly nodes. 3. Unfoldings: DXF format (considering the K-factor of bending). 4. Specification table (BOM): All stainless steel fasteners.

Quantity Surveyor needed for detailed analysis of a construction project We are looking for a specialist to thoroughly analyze the project documentation of a construction site and prepare a detailed list of all materials, volumes, and types of work.Main Task Based on the project documentation, a complete quantity take-off of the project must be performed, and a transparent table of all construction materials and volumes must be prepared. The initial data may include: architectural drawings — AR; structural drawings — KJ / KM; specifications; PDF; DWG; Excel files; if available — BIM/Revit model. We need not just a general construction estimate, but a maximum detailed Quantity Take-Off and Material Breakdown.What needs to be done 1. Complete Quantity Take-Off Calculate the actual volumes according to the project: concrete by grades and structural elements; reinforcement broken down by diameters; metal structures; formwork; blocks and bricks; cement; sand; gravel; plaster; floor screed; waterproofing; roofing materials; facade materials; tiles and stone; ceiling materials; door and window structures; glass; wood; paint; fasteners; consumables; other materials present in the project. The list should be formed as detailed as possible, without combining different materials into general positions. For example: Reinforcement Ø8 — kg Reinforcement Ø10 — kg Reinforcement Ø12 — kg Reinforcement Ø16 — kg Concrete B25 — m³ Concrete B30 — m³ AAC Block 100 mm — m² / pcs. AAC Block 150 mm — m² / pcs. 2. Breakdown by project sections All volumes must be structured at least by the following categories: Foundation; Structural Frame; Slabs; Walls; Roofing; Facade; Flooring; Ceilings; Doors & Windows; Waterproofing; Finishing Works; External Works; other project sections. It is also desirable to separate materials by floors, buildings, villas, blocks, or zones of the site, if the project structure allows. 3. Material Breakdown A separate table of all materials needs to be prepared in the format:SectionMaterialSpecificationUnitQuantity The goal is to obtain a complete list of materials required for the construction of the site, with actual quantities. 4. BOQ — Bill of Quantities A structured BOQ needs to be prepared separately:SectionWork ItemMaterialUnitQuantity If possible, also separate: Materials; Labor; Machinery / Equipment; Transport; Waste Allowance. The main task is to ensure the ability to see the net cost of materials separately from the contractor's work cost. 5. Excel model The final work must be provided in Excel. Desired format:CodeBuildingFloorSectionMaterialSpecificationUnitDesign QuantityWaste %Purchase QuantityUnit PriceTotal Cost Additional Task It would be an advantage if the specialist can create a template system for future projects. Our goal is to use a unified structure Cost Database for analyzing different construction sites in the future. We want to be able to compare: concrete, kg of reinforcement, and materials per 1 m² of construction; cost of structures per 1 m²; materials for one room; materials for one villa; cost of individual construction elements; planned volumes against actual purchases; potential material overruns. Requirements for the Specialist We are looking for a person with practical experience: reading architectural and structural drawings; working with AR, KJ, and KM; Quantity Take-Off; BOQ; construction estimates; analysis of construction volumes; Excel. Important We do not need just a rough estimate of the total project cost. We need a specialist who can break down the project to the level of individual physical materials and quantities. The main result of the work: A complete and verifiable list of all construction materials and volumes of the site that can be used for procurement, tenders, cost control, and checking for overruns. When responding, please indicate: Your experience working with AR, KJ, and KM. Examples of completed BOQs or Quantity Take-Offs. Which programs you work with. Can you work with PDF, DWG, and Revit. How you verify the accuracy of calculations. What format of source files you need. Your cost for the project or cost per m². (Project 1000m²)

Project Description:I am looking for an electronics engineer for a paid technical consultation on repairing network equipment.Problem Summary:There is a 4-channel GSM-VoIP gateway GoIP4. The device has started to go into a cyclic reboot (the relays click every 2 minutes, it does not accept calls, and it resets authorization).What has already been checked:The power supply has been replaced with a known working one (12V/2A) — the problem persists.SIM cards have been removed and checked — the symptoms are the same without them.The problem is 99% likely to be in the hardware (internal power circuit on the board, degraded capacitors, or a burnt-out DC-DC converter).What is required from the contractor:Consult on typical issues with this board and suggest which power circuit elements should be checked first with such symptoms.Important: If you are located in Cherkasy (or are willing to accept the board via Nova Poshta), we can arrange for physical diagnostics and re-soldering of components as part of this project.Please respond if you have experience in component-level repair of motherboards, routers, or similar telecommunications equipment.

The type-C must match the hole on the step model : It should look impressive for the model + don't forget about the monitor output! Best on black textolite And to avoid the obvious impression that it is not working :) (for the average user) Show me the board in the case
