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)

Technical task: Development of design documentation (DD) for thermoboxes (insectariums) Goal: To develop drawings for the production of two types of dismountable thermoboxes made of matte stainless steel for further export. GENERAL DESIGN, LOGISTICS AND QUALITY REQUIREMENTS • Operating conditions: Working temperature inside — 30°C, humidity — up to 80%. The design must be resistant to stable heating and high humidity, ensuring the tightness of joints. • Material: Stainless steel AISI 304, surface — matte. • Hygiene and smoothness: The inner surface must be as smooth as possible. Minimize the protrusion of nuts, ends of threads, or any fastening elements inside the structure. * Task for the designer: Propose fastening options (embedded parts, hidden connections, etc.) so that the inner walls are even. • Quality and appearance: Professional "commercial" appearance, absence of any gaps after assembly. • Export orientation: Assembly should be as intuitive as possible for the end user (export version). • Walls: "Sandwich" (matte stainless steel AISI 304 + basalt wool 50 mm). The thickness of the metal for the frame and cladding must be agreed upon with me. • Assembly: Easy to assemble, non-welded, with bolts (stainless steel A2/A4). • Dimensions and logistics: The basic size of the filler plates is 1000 x 600 mm. The basic dimensions of the products can be adjusted only with my approval (the customer). • Equipment and options: Legs 30 mm, lamp mounts, IR film mounts, seating places for internal racks/supports. Cable passages: Sealed, for leading wires outside. Bar for the shield. • Protective mesh: All ventilation openings are protected by stainless mesh (cell 0.8 mm, wire 0.5 mm), fixed with pressure plates without holes in the mesh itself. PRODUCT №1: Vertical box (2000 x 1200 x 800 mm) • Door construction: Double-leaf across the entire width of the facade (1200 mm), trims, rubber seal. Viewing window: Double-layer on one of the leaves, height 500 mm, pressure frames (2–5 mm). Additional "vent" at the bottom of one of the leaves. Locking — mechanical latch. • Ventilation: ◦ Lower intake: 2 openings (left and right), size 400 x 100 mm each, with dampers. ◦ Upper exhaust: Mounting place for a fan 120x120 mm on flange (M4 fastening, center distance 105 mm). The size of the opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper. PRODUCT №2: Small box (900 x 600 x 600 mm) • Construction: Side doors across the entire panel, trims, rubber seal. Inside — removable/adjustable shelves. • Ventilation: ◦ Intake: 2 openings on the sides of 400 x 100 mm each, with dampers. ◦ Top: Mounting place for a fan 120x120 mm on flange (M4 fastening, 105 mm), opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper. TASK FOR THE DESIGNER: Propose optimal fastening nodes, sealed passages, and a frame design without welding. Be sure to propose design options that minimize the protrusion of any fastening elements (nuts, threads) into the internal space. The goal is a reliable, sealed structure without gaps, with a professional "commercial" appearance. REQUIRED RESULT: 1. 3D models (STEP / SolidWorks) + interactive assembly (Autodesk Viewer). 2. Drawings of parts and nodes (connection diagrams, fastening of nets/glass/lights/IR film). 3. Unfoldings (DXF) taking into account bending coefficients. 4. Specification for stainless fasteners. 5. Proposals for design solutions, timelines, and costs.

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
