3.13.2.1 Environmental Management
On the 16 December 2011 the annual inspection of
the Wambo Homestead Complex (WHC) was
undertaken by a structural engineer. The objective
of the assessment was to determine if any damage
to the Wambo Homestead buildings was attributed
to ground vibration. In the opinion of the structural
engineer, ‘...the Wambo Homestead buildings are
not vulnerable to normal blasting, but that elements
of individual buildings are subject to damage when
large blasts result in ground wave frequencies which
are similar to characteristic frequencies of those
building elements. The only damage possibly
caused by blast vibrations in the period was that
which happened in April 2011. Again, damage was
only of a cosmetic character, did not affect the
structural integrity of the buildings, and could be
readily repaired with normal maintenance.’
The annual archival photographic record of the
WHC was undertaken in November 2011. Copies
of the Archival Photographic Record November
2011 were sent to NSW Heritage Office, DP&I and
SSC in March 2012.
In accordance with the 2006 Conservation
Management Plan for the WHC, routine pest
inspections and baiting programs for termites and
rodents continued.
During the reporting period, Godden Mackay Logan
Pty Ltd (GML) was commissioned by WCPL to
review and update the 2006 CMP for the Wambo
Homestead. The review of the CMP was necessary
as part of planning by WCPL for the ongoing
conservation and management of the Wambo
Homestead Complex and to meet the requirements
of the relevant statutory authorities.
The focus of the CMP review was to provide
appropriate conservation policies for managing the
significant heritage components and values of the
Wambo Homestead. The review examined the
current conditions and future management options
to identify the relevant opportunities and constraints.
The condition and integrity of the Wambo
Homestead was also re-examined and reviewed
recording the changes due to both the passage of
time and the recent programmes of maintenance,
stabilisation and repair works.
Voluntary Action Plan
On 02 December 2010, representatives of WCPL,
DP&I and the Heritage Branch conducted an
inspection of the Wambo Homestead (WH), to
determine compliance with Condition 59 of the
Wambo Development Consent (DA 305-7-2003).
During the inspection it was identified that, although
WCPL had completed maintenance activities
including yard maintenance, installation of a fire
suppression system and other maintenance
activities listed in the 2006 Conservation
Management Plan (CMP), it was also identified that
some additional works would improve WH
conservation.
As a result WCPL, committed to a Voluntary Action
Plan (VAP) to work with the Heritage Council to gain
approval for the proposed VAP works. Completion
of these works would ensure continued
maintenance of the WH in accordance with
Condition 59.
The maintenance tasks and activities committed to
in the VAP were identified during the inspection.
The tasks/activities were divided into two tiers:
Tier 1: Those tasks that can be completed
without further assessment or approval; and
Tier 2: Those tasks that will require approval
from the Heritage Branch and/or further
assessment and planning by a suitably qualified
architectural/heritage consultant prior to
commencement.
The following photos display some of the tasks and
activities completed as part of Wambo Voluntary
Action Plan regarding the maintenance works at the
Wambo Homestead Complex.
