BUILDING MAINTENANCE UNIT MANAGEMENT PLAN

1. INTRODUCTION

The primary aim of this management plan is to provide the following:

• a safe means of using the Building Maintenance Unit (BMU) to access the facades of Selborne & Wentworth Chambers;

• to ensure that only authorised and properly trained persons are able to use this machine in any way;

• to ensure the safety and convenience of the public and of building occupants, and;

• to guarantee that all types of work intended to take place from the unit does so in a safe and unilaterally approved fashion.

The management plan has incorporated a number of sources of information and has addressed the responsibilities of the building owner and primary operator of the machine to provide a set of checks and procedures that will be in state of constant review and evaluation to achieve the operational goals listed above. The products of the management plan are;

a) Operator Training & Operators manual. b) Individual pre-work assessment process. c) A safe work method statement. d) Log book record e) Operator completed operations checklist. f) Operator safety assessment. g) Procedural review process.

1.1. Façade History

The facades of Selborne and Wentworth Chambers maintain the legacy of a building constructed almost 50 years ago. The aging face of the building requires regular inspection and periodic repair to ensure the structural integrity of the building and to ensure the safety of building occupants and the public. Access has traditionally been via rope access for the purpose of inspection and minor repair, and major repairs have required the


2

use of more cumbersome means of access, such as masterclimbers, cherry pickers and swing stages.

1.2. Heating, Ventilation and Air Conditioning When the building was built, central ventilation, heating and air conditioning was not a priority in design. As a result, the building relied on natural ventilation through Chambers windows to provide temperature regulation, and over the last decade and a half, window and split system air conditioning units have assisted to provide cooling capacity and heating. Access to these units, for service or installation has been via the windows in Chambers, and thus the installations have been compromised as a result of impaired access. Service of the façade units occurs once a year and requires the use of a cherry picker, necessitating a partial road closure and only a limited time frame in which to perform the required work. The disposal of condensate has also been a problem in the building, as access to the facades on a general level has been restricted and in some places completely unavailable.

1.3. Window Cleaning

The cleaning of windows in Selborne & Wentworth Chambers has traditionally been performed with the use of abseiling to access the facades and windows. This method provides an effective means of access for this type of work, however rope access is the least preferred method of façade access according to WorkCover NSW.

1.4. The BMU for Selborne & Wentworth Chambers The decision to purchase a BMU for Selborne & Wentworth Chambers was made after considering the requirements for façade access and to provide access to the relevant contractors to perform the various works that will be required on each of the buildings facades.


3

The BMU was purchased and installed by Building Maintenance Units Australia Pty Limited (BMU’s Aust.). The installation was supervised by Jim Campbell & Associates Pty Limited (JCA). In addition to; • façade maintenance; • air conditioning service and installation, and; • window cleaning, The immediate short term requirements for façade access include; • Building Code of Australia upgrade sprinkler installations; • condensate disposal system installations; • long term façade option studies, and; • emergency façade access situations. The purchase of the BMU to achieve access as described above must be accompanied with the appropriate training and procedures.

2. RESOURCES & PUBLICATIONS

2.1 Resources The resources used to develop this management plan follow:

• AS 2550.13 – 1997 Cranes – Safe use – Building Maintenance Units. • WorkCover NSW Publications including ‘Risk Management at work –

Guide 2001’. • The City of Sydney and their procedures for working over public

spaces. • The BMU Manufacturers on site practical training. • The Manufacturers operating manual for the machine. • A Hazard Identification and Risk Assessment including the control

4. BMU SECURITY – RESTRICTING UNAUTHORISED ACCESS

Those who will be requiring regular access will be:

• Building owners • CCL Maintenance staff • Window cleaners • AC installers • Façade Engineers • Glaziers • Builders

Those requiring one off access and modified training will be:

• Any other contractor requiring one off access for

unique work.

To ensure that only authorised persons use the machine, a series of processes must be followed prior to the building manager issuing the keys and the equipment necessary to operate the BMU. All operators, wether they require regular or casual use of the machine must complete a SWMS + Checklist + Logbook for every day that they are on site and for every different job that is undertaken. Work on the Phillip Street Façade can only be conducted on weekends and a charge will be levied to cover the cost of the required Council permit. Normal weekend operating hours are from 7am to 5pm on Saturday only. Special arrangements must be made to use the BMU on a Sunday. Work can start at 6am during the week. For Barristers on the Phillip Street façade of the building they will be able to have the use of the BMU on Sunday’s without extra charge, if they are unable to guarantee the use of the machine on a Saturday. Conditions change from time to time and the procedures must reflect these changes.

5.2 Window Cleaning – Hazardous Materials

The cleaning of windows requires particular attention as the window mastic contains asbestos. There precautions and measures must be taken to ensure that the ongoing safety of building occupants and BMU operators.

MEMORANDUM: TRACES OF ASBESTOS IN WINDOW MASTIC The mastic in the windows of Selborne & Wentworth Chambers contains traces of asbestos. The mastic surrounds the glass in the window panes, providing a seal for the window. The affected windows are those that are original to the building. The new windows in Selborne & Wentworth Chambers, which are bronze in colour, are not affected and do not utilize mastic containing asbestos. CCL has been advised that provided the mastic remains in good condition and is not disturbed it presents no material danger. A management plan has been developed and implemented by CCL to address the risk associated with the window mastic. The plan involves testing, inspections and ensuring that some simple rules are observed. Under the plan the following measures must be strictly observed by all occupants of and visitors to the building: • The mastic must not be disturbed, removed or damaged in any way. • All persons occupying space in Chambers must be aware of the

presence of asbestos in the window mastic. • The mastic has been sealed and CCL has been advised that it

presents no danger in its current form, however it must remain in place and remain undisturbed.

• All building work carried out in Chambers must be approved by Counsel’s Chambers Limited prior to any work taking place and must be carried out in accordance with the Rules for Tradespersons and Contractor on site Procedures.

• Counsel’s Chambers must be notified of any intention to repair or replace air conditioning units. This type of work may affect the window mastic in which case the appropriate safety measures will need to be put in place.

• The replacement or removal of glazing is prohibited unless prior notification is submitted to and approval obtained from Counsel’s Chambers Limited. Counsel’s Chambers Limited will require advice to be obtained from an Environmental or OH&S Consultant and any work that is to be carried out on the windows that will affect the window mastic will require that the mastic is removed by a licensed asbestos contractor.


12

5.3 Window Cleaning – Procedures

The following instructions outline the process for cleaning windows:

• The cleaning of windows in a conventional manner using squeegees and sponges has the potential to disturb the in situ mastic containing asbestos.

• All exposed surfaces of the mastic containing asbestos

agents within the external window frame have been sealed with a suitable fibre bonding agent.

• All window cleaners must be aware of the presence of

asbestos so that the material is not disturbed and that any accidental damage is report to Counsel’s Chambers Limited.

• The condition of the material will be inspected on a regular

basis to ensure the condition of the material is not deteriorating or otherwise contributing to an unacceptable health risk.
