Health Infrastructure engaged a project team to conduct a Preliminary Site Investigation and Detailed Site Investigation to form the basis of any future redevelopment. This is a historic site with the original Denistone House dating back to 1806. The southern portion of the site consists of Blue Gum High forest which holds great environmental significance.

Monteath & Powys were engaged to complete a full 3D survey of the entire site including underground service modelling creating a digital twin. This posed significant challenges being a working hospital during the Covid pandemic. A strategy was implemented to reduce field times by completing all works by 3D laser scanning. This allowed us to capture the entire site to millimetre accuracy within one week on site minimising our site times and interactions with staff and patients.

The 3D laser scan was processed in the office with all site features extracted from the digital twin as an office based process. Features are extracted and exported to software packages such as AutoCAD and Revit which can be utilised by most engineers and architects.

A full title search and cadastral model was created and overlaid within the 3D model showing accurate locations of boundaries and easements.

Underground services were traced on site electronically and incorporated into the overall 3D model. This enabled us to deliver both the 3D points cloud model (digital twin) and traditional survey outputs which can be used from concept to final design.
