PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                 6 OCTOBER 2020


    The building does not meet the energy efficiency requirements for the National
     Construction Code Internal room sizes do not suit the equipment or functional requirement
     of an imaging and medical centre
    Inability to add lead lining to existing walls required for x-ray equipment due to additional
     weight impact on existing inadequate structure
    Inability to install, service or replace imaging equipment due to existing roof framing
    Electrical system is inadequate for proposed use
    Plumbing and drainage system is inadequate and unsuitable
    A range of WHS issues that would require modification to the existing building
    Suspicion of existing lead paint beneath external (an internal) finishes which would be
     required to be completely removed or encapsulated which would substantially change the
     appearance of the building
    None of the interior or exterior walls would achieve the required acoustic ratings for
     imaging and medical centre
    Commercial grade specialist solution mechanical system is required for medical and
     imaging fit outs which could not be accommodated within the existing building fabric
The applicant provided a further report from Bligh Tanner dated 21 July 2020 which provided a
structural assessment of the existing house for adaptive re-use as a medical centre. This report
identified the following upgrade works as being required:
    The complete dwelling should be raised and temporarily supported while the existing
     stumps and block walls are removed, after which new footings, stumps and perimeter block
     walls should be installed. The floor will require re-levelling.
    All floor framing members would need to be strengthened for the increased live loading
     allowance (e.g. allow for splicing existing timber bearers and joists with members to match
     existing size to increase the capacity). - All floorboards would need to be removed and
     replaced to allow for the increased live load allowance.
    Majority of internal walls would need to be demolished and temporary propping of existing
     roof structure and external walls required. Transfer beams, roof support framing and
     internal walls would all need to be designed to suit proposed medical centre floor layout.
    External wall cladding would require removal and replacement for installation of acoustic
     treatment and thermal insulation and installation of bracing wall elements.
    Remove and replace external walls with walls achieving required FRL where walls are
     within 3m of fire source feature (e.g property boundary).
    Upgrade roof framing to strengthen where required and upgrade to current codes and
     building practices. Allow for strengthening of roof framing to specialist equipment areas
     where support from roof structure is required (CT scanner, X-ray gantry).
    Remove and replace external cladding due to widespread visible damage, paint flaking,
     discolouration and rust stains around nail heads.
    Modifications to front entry to comply with provisions for universal access (e.g. installation
     of ramps or lift access).
These documents were referred to Council’s Building Certifier and to Council’s Heritage
Coordinator for review and comment. The comments note that it is commonplace for existing
buildings to be altered, particularly where involving changes of classification, whereby the
existing building is modified to achieve compliance with relevant legislation. In this regard the
comments noted the following:
