What are Mechanical Drawings?

Mechanical drawings encompass the HVAC (Heating, Ventilation and Air Conditioning) complexities of a building. They are an important part of large construction projects such as industrial offices, shopping centres and office blocks. Mechanical drawings are speciality drawings used to determine the layout, configuration, cost and energy efficiency of the project from a mechanical engineering perspective.

What to Use to Mark Up Plans?

Thanks to technology, you can now mark up mechanical drawings with your iPad or laptop with the simple click of a button using programs such as PlanGrid, PDF Annotator and Drawboard PDF.

Can I use photographs to show specific details?

Yes, you can. Photographs provide a real-life record and enable a clearer understanding of measurements or specific details. We will accept photographs, sketches, original drawings and handwritten text to collate and combine.

Can I Mark Up hard copies?

Yes, start with a draft pencil mark up, this will ensure all notations fit the page and can be easily read, and all plans should be scanned in colour at 300 dpi at the native page size.
