Description and value of services provided by the consultant.

Nova Group Pacific was engaged to undertake site contamination/ hazardous materials assessments and remediation works.

The following services and reports were also provided to the client.

1. Head Contractor Responsibilities

As Head Contractor, Nova Group Pacific had the responsibility of organising contractors, clients, and community members to ensure the project is completed in a safe and timely manner. Part of the pre-works included the preparation of documents such as an Environmental Management Plan (EMP), Quality Management Plan (QMP), Traffic Management Plan (TMP), and dilapidation reports for each site.

This then extended into overall supervision of all workers on site to ensure management plans were being adhered to.  

2. Pre-demolition Hazardous Materials Survey

One major part of the project's scope was to demolish an abandoned asbestos containing building, situated in the middle of the community. Before doing so, a pre-demolition hazardous materials assessment was conducted to ensure the demolition works were done in accordance with SafeWork NSW regulations.

3. Asbestos Clearances

Each house that underwent asbestos removal works or demolition required air monitoring and an asbestos clearance before handing over of the sites back to the client. These removal works were certified and deemed safe by Nova Group Pacific as the acting Licensed Asbestos Assessor (LAA) in the form of an asbestos clearance certificate.
