Part C – Implementation Tools<br />

142 Old Parliament House and Curtilage Heritage Management Plan <strong>2008–2013</strong><br />

5 NON-DESTRUCTIVE INVESTIGATIVE TECHNIQUES<br />

5.1 VISUAL INSPECTION<br />

Visual inspection is a non-destructive technique that involves looking for visual clues about the physical nature<br />

or condition of a building. An experienced eye will usually find an array of clues that may reveal information<br />

about the type of building materials, the type of construction method, and a broad range of similar details.<br />

Advantages<br />

Disadvantages<br />

— Quick; cost effective; may be reasonably carried out by any informed individual<br />

— Relies on the inspector maintaining concentrated focus over an extended time,<br />

may not identify subtle or hidden clues<br />

Permitted Actions<br />

Visual inspection of all heritage fabric using any means<br />

available provided that no intervention or damage<br />

is caused to the heritage fabric being inspected.<br />

Use of any tools/equipment enabling access to heritage<br />

fabric for the purposes of visual inspection provided<br />

that all heritage surfaces such as floors and walls<br />

are adequately protected from potential damage.<br />

Repositioning of movable furniture or other portable<br />

items to enable access for visual investigation<br />

provided it is carried out in accordance with the<br />

Housekeeping Permitted Action Schedule and<br />

after consultation with the OPH Heritage staff.<br />

Not Permitted Actions<br />

Removal, either temporarily or permanently, of any<br />

existing building fabric for the purposes of visually<br />

inspecting fabric that is currently hidden from view.<br />

Use of any tools/equipment providing access to heritage<br />

fabric without adequate protective devices in place to<br />

protect heritage surfaces such as floors and walls.<br />

Repositioning of movable furniture or other<br />

portable items to enable access for visual<br />

investigation without reference to the<br />

Housekeeping Permitted Action Schedule or prior<br />

consultation with the OPH Heritage staff.<br />

5.2 SURFACE MAPPING<br />

Surface mapping is a non-invasive method for investigating sub-surface details of built fabric<br />

using a high-powered, portable light used at an angle on a flat surface. The method relies upon<br />

senses of sight and touch. It is the best tool for examining surfaces in dark spaces.<br />

The use of surface mapping is a permitted action appropriate for:<br />

■■revealing every perceivable detail of former attachments, repairs or alterations<br />

■■identifying potential structural or environmental problems<br />

■■verifying the need for other forms of investigation.<br />

Advantages — Quick; may be reasonably carried out by any informed individual<br />

Disadvantages — May require access equipment<br />

Permitted Actions<br />

Surface mapping of all heritage fabric provided<br />

that no intervention or damage is caused<br />

to the heritage fabric being mapped.<br />

Repositioning of movable furniture or other portable<br />

items to enable access for surface mapping<br />

provided it is carried out in accordance with the<br />

Housekeeping Permitted Action Schedule.<br />

Use of any tools/equipment enabling access to heritage<br />

fabric for the purposes of surface mapping provided<br />

that all heritage surfaces such as floors and walls<br />

are adequately protected from potential damage.<br />

Not Permitted Actions<br />

Removal, either temporarily or permanently, of any<br />

existing building fabric for the purposes of surface<br />

mapping fabric that is currently hidden from view.<br />

Repositioning of movable furniture or<br />

other portable items to enable access for<br />

surface mapping without reference to the<br />

Housekeeping Permitted Action Schedule or prior<br />

consultation with the OPH Heritage staff.<br />

Use of any tools/equipment providing access to heritage<br />

fabric without adequate protective devices in place to<br />

protect heritage surfaces such as floors and walls.
