In Situ Advisory Case Study: Hi-Quality: Cell 3 Detailed Design, Construction Project Management and Construction Quality Assurance

Project Name: Minda Landfill, Cell 3 Detailed Design and Constriction Quality Assurance

Client: Hi-Quality Group Pty Ltd

Discipline: Waste & Resource Management

Date: January 2020 onwards

InSitu Advisory was engaged by Hi-Quality Group to undertake a detailed design of their proposed general solid waste (non-putrescible) waste Minda landfill in Windellama, NSW.  Since January, InSitu Advisory have been working on the design, regulatory approval and subsequent construction of this new composite lined landfill cell.

InSitu Advisory undertook the design in full accordance with the NSW EPA Environmental Guidelines: Solid Waste Landfills, 2016.  EPA approval was achieved after the submission of a detailed Technical Specification, CQA Plan and detailed design drawing set.

InSitu Advisory were also commissioned to provide on-site independent construction quality assurance (CQA) services using experienced in-house specialist engineering staff and project managers.

The development of Cell 3 provides a seamless transition for waste disposal operations at the site from the current Cell 2 area. 

This new cell will provide a significant boost to the region’s ability to handle waste, including significant quantities of waste from bushfire affected areas across southern NSW. 

“InSitu Advisory were chosen to assist Hi-Quality due to their in-depth knowledge of the technical, commercial and regulatory requirements for modern waste and resource recovery facilities. Their knowledge and experience helped ensure a smooth and timely approval process, which allowed construction works to commence sooner than expected. Their on-site CQA service ensured the works were undertaken in accordance with the approved designs, and provided an excellent interface between Hi-Quality and the installation contractor.”
