Classic Infrastructure Logo Needed

I need a fresh logo for my construction firm, RAVIKAN INFRATECH LLP. The mark should feel unmistakably classic rather than trendy, and it has to communicate the kind of civil-infrastructure work we do—think roads, drains and sturdy buildings rather than abstract shapes.

Key points to keep in mind
• The letters R & K must stand out as the visual focus.
• Imagery should reference real infrastructure elements (roads, drainage lines, building silhouettes) so anyone seeing it instantly links the brand to civil construction.
• Colours: keep the palette basic and understated; no shiny or metallic treatments. Flat tones that reproduce well on site boards, helmets and drawings are ideal.

Deliverables
- At least three initial logo concepts.
- Final artwork in vector formats (AI, EPS, PDF) plus high-resolution PNG and JPEG, and a monochrome version for stamps.
- Full usage rights transferred on approval.

If this fits your skill set, please share a concise portfolio link featuring similar construction or infrastructure logos and outline your revision process.
