      * All of the original form and fabric of the Dugout
The condition of these physical elements should be monitored and recorded as part of the on-going maintenance regime for West Block and the Dugout.  See also Policy 14 'Landscape maintenance' and Policy 21 'Recording'.
With regard to the recommended cyclical inspection and maintenance programme, the following sets out a desirable minimum program for cyclical maintenance.
            Annual:  Roof cladding, gutters, downpipes, drains and surface drainage, bird-proofing, roof space, security and fire precautions, plumbing, electrical and data cables and appliances, windows and doors and general safety.  Ceilings, floors, stairs, joinery, fixtures and fittings, tiling and building services.
            4–5 years:  External walls, external joinery other than for windows and doors and lighting.

Repairs
From a heritage perspective it is generally recommended that repairs of significant buildings and structures should involve replacing 'like with like,' i.e. the replacement of material (missing, deteriorated or broken) with fabric to match the existing.  Accepting this principle, it is also important to determine if the material proposed for replacement is appropriate (it may not be original).  The advice of a qualified heritage practitioner should be sought on this.  Wherever possible, only actual decayed fabric of a heritage structure should be replaced, instead of the whole host element.
Repairs to significant structures should also, in preference, be carried out by appropriately skilled staff or contractors, and may require in some cases prior analysis of the composition of the fabric to be repaired/replaced.
Specialist input may also be required for the identification and eradication of any damage caused by pest infestations.  Rectification may involve repair to, or replacement of, damaged fabric.

Policy 13 Hazardous materials
Removal of hazardous materials from West Block should seek to minimise physical impacts on significant values and attributes.
Where hazardous materials are removed, the key consideration from a heritage perspective will be to conduct their removal with minimal physical impacts on the presentation and character of West Block.  This includes recording evidence of early decorative treatments where there is a requirement to remove paint.

Policy 14 Landscape maintenance
Original and early tree plantings, and evidence of landscape character areas, should be retained and enhanced.
Plantings dating to the 1920s should be conserved using appropriate arboricultural methods, to prolong their viability and contribution to the visual legibility and amenity of the landscape integral to West Block.  Arboricultural assessment and maintenance should be undertaken by a qualified arborist with documented experience in assessing and maintaining heritage-significant exotic trees.
While arboricultural works should be undertaken in general conformance with the appropriate Australian Standard, pruning of heritage significant trees is to be conservative in ambition except where required for
