Solidworks PV Carport 3d Variants (Parametric ) CAD Design

Job ID: 40246828

Budget: €250 – €750 EUR

Subject: RFQ – CAD (SolidWorks/AutoCAD) – Parametric PV Carport Variants (Folded Sheet Metal + Aluminium Extrusions)


Scope: Create manufacturable CAD + drawings for 2 PV carport families based on supplied assembly plans (SUNFER type systems):

GRAND PARK Parking Canopy (2–5 bays)

PR1-WT-EN Parking Canopy + Watertight PV profile system (even/odd bays incl. special “functional diversity” bay)

2.1 Reference documents (provided by client)

“GRAND PARK – Assembly Plans (R1-03/24)”

“PR1-WT-EN – Assembly Plans (R2-04/25)”

2.2 Goal

We need parametric CAD models and complete manufacturing drawings to create new design variants inspired by these systems, but optimized for production using:

Folded sheet metal parts (steel or aluminium where appropriate)

Aluminium extrusion profiles (rails, PV guide profiles, trim/gutter, clamps interface)

Standard fasteners and assembly logic

The result must be suitable for quotation, fabrication, and CE/structural documentation preparation.

2.3 Deliverables

A) 3D CAD (parametric)

SolidWorks preferred (2020+), AutoCAD acceptable for 2D but 3D parametric is required (SolidWorks or Inventor).

One master “skeleton/layout” that drives:

Number of bays/spaces (2/3/4/5 for GRAND PARK; even/odd for PR1-WT-EN)

Bay width + overhangs

Roof pitch (8° GRAND PARK, 5° PR1-WT-EN as baseline)

PV module envelope parameters (max module size inputs; portrait orientation)

B) Manufacturing drawings (2D)

General Arrangement drawings (GA) for each configuration

Part drawings for:

Columns / beams / purlins (steel)

Folded sheet metal parts (baseplates, connection plates, covers, trim panels, gutters)

Aluminium extrusions (as “reference profiles” with cut lengths + drilling/punch patterns)

BOM (structured) + cut list

Assembly drawings with item balloons

C) Exchange formats

Native CAD (SLDASM/SLDPRT + drawings)

Neutral: STEP (AP214/242), DXF (flat patterns), PDF drawings

Optional: DWG for GA plans

2.4 Variant design tasks (what you must design)

Task 1 – GRAND PARK inspired variant

Create a manufacturable structure covering 2–5 parking spaces (per kit logic in the reference).

Keep the same functional architecture: two main supports, purlins, aluminium beams/rails, trims/gutter, PV clamps/strips.

Propose a folded sheet metal column concept (instead of heavy welded box) if structurally feasible (with internal stiffeners if needed).

Provide alternatives for:

Column shape: folded trapezoid / folded box / hybrid (folded + welded)

Beam-to-column connection plates (service hatch access where needed)

Task 2 – PR1-WT-EN inspired variant with watertight PV

Model the watertight PV interface system:

Guide profiles (G74/G75/G76 concept)

Longitudinal profile (G77 concept)

End/mid clamps concept (S10.7 / S11)

Provide a parametric layout for:

Even number of bays

Odd number of bays

A special bay option (wider bay / “functional diversity space” as per reference logic)

2.5 Standards & drawing requirements (“drawn to standards”)

Drawings and models must follow common EU manufacturing/engineering standards:

ISO 128 (technical drawing presentation)

ISO 129-1 (dimensioning)

ISO 2768-mK (general tolerances – unless otherwise specified)

ISO 1101 (GD&T where needed), ISO 8015 (GPS fundamentals)

ISO 2553 (welding symbols) – only where welded assemblies are used

Material callouts must be explicit:

Structural steel: S275 (or higher if you recommend)

Aluminium extrusions: EN AW-6005A T6

Fasteners: A2-70 stainless

Corrosion protection callouts:

Hot-dip galvanizing (ISO 1461 or equivalent) for steel components

Powder coat option (specify system + thickness) if variant uses painted finish

Note: Structural verification itself can be excluded from your price if you prefer, but the CAD must be suitable for later Eurocode checks (EN 1991/1993/1999).

2.6 Assumptions to use in CAD (baseline)

PV modules in portrait orientation

Minimum clearance under canopy: 2.20 m

Roof pitch baseline: 8° (GRAND PARK) / 5° (PR1-WT-EN)

Use the reference documents for baseline spans/typical bay sizes; make them parametric so we can adjust later.

2.7 What to include in your quotation

Please provide:

Fixed price per task (Task 1 / Task 2) + combined price

What is included/excluded (especially structural calcs)

Your deliverable list confirmation (native CAD + STEP + DXF flat patterns + PDFs)

Timeline in working days from start

Your hourly rate for extra iterations

Examples of similar steel/aluminium CAD work (links or PDF screenshots)

2.8 Acceptance criteria

Models rebuild without errors and configurations switch correctly (2–5 bays / odd-even logic)

Drawings are fabrication-ready (hole patterns, bends, thickness, material, finish, BOM item numbers)

Clean assembly hierarchy + consistent naming
