Your responsibility will be to independently review the study methodology and calculations, identify any corrections or additional documentation you believe are necessary, and certify/sign the completed study if you determine it is accurate and appropriate. ...

I need a full engineering package for a commercial-grade chest press machine that will live in professional Indian gyms. The machine must handle a 100 kg selectorised weight stack and feel smooth and natural under load. Key mechanical goals • Use a steel tube capsule frame; propose the optimal wall thickness and section size for both strength and cost-efficiency under heavy daily use. • True isolateral movement arms are non-negotiable. I want balanced resistance through the stroke so each side can move independently without crossover. • Overall footprint, seat height, and press path must suit the average Indian user and the tighter floor plans common here. Aim for a compact stance without sacrificing full chest engagement or shoulder safety. • Specify bearing t...

I’m looking for an experienced MCC electrical engineer to prepare fully detailed control-panel layouts for a new motor control center I’m building.

I’m happy for you to work in AutoCAD Electrical, EPLAN, or a comparable CAD platform as long as the native files and PDFs are delivered. Deliverables • Scaled control-panel layout drawings, showing component placement, wireway, and clearances • All supporting schematic pages referenced by the layouts • Bill of materials tagged to each drawing • Final ...

I need a full engineering design for a bored cast-in-situ pile, 600 mm in diameter and 21 m deep, capable of carrying 175 tonnes. The piles will support a multi-storey commercial building to be erected on sandy soil, so the design must reflect both the reduced shaft friction typical of this stratum and the higher potential for scour near the surface. Please include all geotechnical and structural calculations, load-settlement analysis, reinforcement detailing, and a clear layout plan showing pile spacing, cut-off levels, and cap geometry. I also expect a concise design report referencing the governing code you choose (IS 2911, ), together with editable drawings in DWG or REVIT and a sealed PDF set ready for permitting. Deliverables: • Design brief with assumptions and safety factors...

I need a seasoned CAD professional who can take my PDF reference drawings and turn them into production-ready CAD assets. The core of the job is accurate 2D technical drafting in AutoCAD, but I also want the matching 3D models created in SolidWorks for the associated mechanical parts, full assemblies, and any sheet-metal components. Precision matters: every view must carry correct dimensions, tolerances, and clear annotations so the files can move straight to manufacturing. Clean layer management, proper line-weights, and a tidy title-block are essential. Preferred workflow • I send you the PDFs and any quick notes. • You return a first pass so I can mark up anything that needs tweaking. • Final deliverables arrive on the agreed date. Required output formats DWG a...

I will supply clear dimensional sketches of the steel component along with the static load distributions that it must withstand. From those hand drawings I need you to recreate the geometry in your preferred FEA-capable package—ANSYS, SolidWorks Simulation, Abaqus, or another fully-licensed tool you trust—mesh it appropriately, and run a complete linear static analysis. The finished work should give me: • A clean CAD model that reflects every dimension shown in my sketches. • Screenshots of the mesh and boundary-condition setup so I can see exactly how the loads and constraints were applied. • Result plots for stresses, displacements, and load concentrations, with the critical zones clearly marked. • A concise written report (PDF) summarising the fac...

I need a complete Autodesk Inventor model for a set of industrial fixed stairs.
