Abstract

Heritage buildings and structures under redevelopment or rejuvenation require detailed information for visualisation and decision making. This information - used by Engineers, Architects and Builders for reinforcement, redesign and preservation requirements is critical for ensuring preservation and rejuvenation works are successful. Typically, these Engineers, Architects and Builders are given the responsibility of preserving these important Heritage buildings and structures, but only supplied access to this information in the form of (often dated) design plans or the original drawings which often do not reflect the true dimensions of the as built environment. If these original drawings are used, the implications on structural decisions could be catastrophic for the building/structure; as well as the site surrounds. High-Definition Surveying is an established solution tool for recording Heritage Buildings, Facades and Structures (such as Masonry Arch Bridges) due to its ability to comprehensively record, store and supply accurate as built deliverables for use on projects using Terrestrial 3D Laser Scanning. The Technology provides benefits through efficiently acquiring true site conditions in a raw "point-cloud" format, which can be supplied as up-to-date existing conditions CAD Plans, 3D Models and Tru-View datasets for use in decision making, visualisation and analysis by project stakeholders. The early engagement of High-Definition Surveying (HDS) in the form of 3D Laser Scanning or Automated Monitoring Services for the redevelopment or rejuvenation of Heritage sites has assisted in critical decision making and interpretation; confirmation of interference/clash detection; verification of heritage "imperfections" or asymmetry; and monitoring over time with a higher ability to interpret and analyse construction impacts on heritage features - in comparison to Conventional Surveying Methods. High-Definition Surveying has provided proven time and cost savings for recent AAM projects, as well as assurances (with confidence) that the heritage structures are in the same - or better - condition post construction or rejuvenation works; and this paper presents and outlines several ways AAM's High-Definition Surveying team has supported Engineers, Architects and Builders in the recording, monitoring, rejuvenating and preserving of Heritage Facades and Buildings - as well as Structures and Bridges - through case studies and introductions to the technology from an end-user perspective.
