Site Design and Mark Out

Precision and planning are at the core of any successful event build. At Technical Overlay, our site design & mark out service ensures that every asset lands exactly where it should, with no surprises on the ground. Whether we’re working from existing CAD drawings or building a layout from scratch, our experienced team takes your creative and operational vision and turns it into a practical, deliverable plan.

Using the latest GPS and surveying tools, we provide accurate on-site mark out for everything from structures, stages, and power infrastructure to back-of-house compounds, vehicle routes, and emergency access points. We assess gradients, ground conditions, and utilities early in the process to flag any constraints—long before boots hit the ground.

Our capabilities include:

  • Full CAD drawing production and layout design
  • GPS-accurate ground marking for all infrastructure
  • Site access planning and traffic flow coordination
  • Integration of power, water, and waste infrastructure
  • Zoning for audience, staff, and operational areas
  • On-site coordination with build teams and contractors

Whether you’re working with a greenfield site, a sensitive heritage venue, or a city centre location, our team brings structure and foresight to every step—reducing delays, improving safety and streamlining the build. Let us handle the mark out so your site starts right, every time.
