Work, Health and Safety Requirements

Formal Work Health & Safety Requirements Under the Work Health & Safety Act 2012 (SA), the Councils have a duty as a “person conducting a business or undertaking” (PCBU) to provide and maintain, so far as is reasonably practicable, a safe working environment for its employees, tenderers, contractors, sub-contractors, consultants, visitors and members of the public. To align with The Councils’ WHS duties, the successful Tenderer must comply and ensure that others comply with the following:

1. The Tenderer engaged in providing the Services must identify and discharge their own duties as a PCBU;

2. The Tenderer must ensure through a documented and systematic approach, that it complies with any Acts, regulations, local laws and by-laws or Guidelines applicable to the performance of the Services; and

3. The Tenderer must comply with any reasonable directions of The Council’s Contract Representative relating to safety and environmental matters if they arise.

General Advice It is the responsibility of the contractor to comply with relevant state WHS legislation, relevant codes of practice, Australian standards and for reporting unsafe or unsatisfactory working conditions, hazards and incidents.

The Contractor is to complete and provide all relevant Safe Work Method Statement (SWMS), Job Safety Analysis (JSA), Risk Assessment (RA) or Safe Work Instruction (SWI) paperwork to the Council.

Safe Work Method Statement (SWMS) is a document which records the significant (prescribed) information relating to WHS for a construction project.

7 | P a g e

Job Safety Analysis (JSA) simply means looking at the work task and considering what is the safest way to complete it. It is a way of becoming aware of the hazards involved in doing the job and taking action to prevent an injury. The JSA form will allow you to record that the safety assessment has been carried out.

A Risk Assessment (RA) identifies the hazards and evaluates likelihood and consequences of a potential incident.

A Safe Work Instruction (SWI) lists the possible issues for a known work situation or environment and allows you to check that there are no changes that may create new hazards or issues that compromise safety.

The above documents will assist in deciding the following:-

Eliminate the risk The most effective control measure involves eliminating the hazardous manual task and its associated risk. Minimise the risk If it is not reasonably practicable to eliminate the risk, then you must minimise the risk so far as is reasonably practicable.

More Information on WHS requirements are available at www.safework.sa.gov.au The Tenderer shall provide copies of safe work procedures and practices relating to the Works to be undertaken as part of the Tender. Reporting Hazards / Issues / Near Misses In the instance of any incident, assessed hazard or near-miss the Councils Superintendent should be contacted as soon as safely practicable and informed of the situation so that the Council can ensure the appropriate steps have been taken and the incident recorded and reported.

Conflict of Interest

Contractors must inform Council of any circumstances or relationships which will constitute a conflict or potential conflict of interest if the Contractor is successful. If any conflict or potential conflict exists, the Contractor must advise how it proposes to address this. If any conflict or potential conflict of interest is omitted, Council may suspend the whole or any part of the Works if considered necessary.

1 PRELIMINARIES

1.1 Background

The Auburn Recreation Grounds (the Grounds) incorporates the Caravan Park, Community Centre, and

Sporting clubhouse.

Wastewater management at the Grounds has relied on an existing domestic Ri-Treat Aerobic treatment unit

(AWTS), which is undersized, especially during the holiday season when the caravan park is busy.

Council requires an upgrade of the wastewater facilities to adequately manage current loads and also provide

additional capacity for future growth. For this reason, the proposed upgrade has been separated into two

stages, firstly to address current under-capacity and, secondly, to incorporate into the design the infrastructure

required for future expansion for when that becomes necessary.

The following assessment evaluates site and soil conditions, design criteria, and construction requirements, in

accordance with the SA Health Onsite Wastewater Systems Code, 2013, (DHA code). A layout of the site is

provided in Figure 1-1.

It is important as part of the tender brief, that submissions include the proposed construction methodology and

outline the management approaches to minimise the impact on car parking and pedestrian movements.
