Civil & Mining Construction

---

Client: Shamrock Civil
Timeline: 19 Jan 2022 – 22 Mar 2022

Scope of Works:

HPR was engaged to oversee the construction of a large-scale gas evaporation pond, bringing in a full complement of equipment and skilled personnel. The scope included supplying two CAT D10T dozers, six scrapers, and eight highly skilled operators, supported by on-site diesel fitters for mechanical assistance. The work began with loading, hauling, and placing topsoil from the pond footprint, followed by ripping and conditioning the pond floor material to the optimal moisture content (OMC) using the dozers and a water truck.

To construct the dam walls, the conditioned material was loaded, hauled, and placed using the scrapers. The fill was then compacted with a CAT 825 compactor to ensure it met the project's specifications. Finally, topsoil was placed and seeded along the batters of the dam walls for environmental stabilization. HPR's team and equipment worked seamlessly to deliver the project with precision and efficiency.

Timeline: 29 Aug 2022 – 20 Dec  2022

Scope of Works:

HPR was engaged to support the rehabilitation of a decommissioned gold mine, which required the management and reshaping of 280,000m³ of cut and fill material. This included shaping spoil stockpiles and backfilling legacy tailing cells according to engineered designs, utilizing GPS technology to ensure precision in line with RPEQ specifications. 

A key part of the project was the loading, hauling, and placement of topsoil across the reshaped areas to a nominal depth. To ensure environmental stability, the topsoil was deep ripped, ameliorated, and seeded, promoting the restoration of the land.

The scope also included the provision of a full fleet and workforce. This consisted of three CAT D10T dozers, four CAT 631 scrapers, one grader, one water cart, and two 30-ton excavators. Additionally, the project was supported by two on-site diesel fitters and a team of 11 experienced operators, ensuring that all work was completed efficiently and to a high standard.

Client: Pensar Projects
Timeline: 9 Nov 2020 – 11 Aug 2022

Scope of Works:

HPR was engaged by Pensar Projects to support the construction and ongoing maintenance of the tailings dam tip head at the Ravenswood Gold Mine. The project

operated on a 24-hour schedule, with HPR supplying a dedicated CAT D10T dozer and four experienced operators working on a rotating 7-on/7-off day and night shift roster.

To ensure uninterrupted productivity and plant

availability, HPR provided full-time on-site mechanical and operational support, significantly reducing downtime and maintaining consistent delivery throughout the

nearly two-year engagement. Our ability to self-manage and respond quickly to site needs was instrumental in the project’s success and our continued relationship with the client.

Scope of Works:

HPR was engaged to undertake the rehabilitation of the overburden stockpile at Glencore’s Clermont Coal Mine. The scope of work included terracing the side of the stockpile down three levels, all done to precise GPS design specifications. Haul roads were constructed to ensure access to all work areas, allowing for efficient operations throughout the project.

Topsoil was loaded, hauled, and placed using scrapers across all terraced levels to the required nominal depth. Once the topsoil was in place, all areas were graded to meet final GPS tolerances. The placed topsoil was deep ripped to provide compaction relief, followed by seeding to promote environmental stabilization. A full fleet and workforce were supplied for the project, which included two CAT D10T dozers, four CAT 631 scrapers, one grader, and one water truck, ensuring the project was completed to the highest standards.

Timeline: 11 Apr 2023 – 18 Nov 2023

Scope of Works:

Heavy Plant Rentals (HPR) was engaged by Harlow Civil to deliver critical civil infrastructure supporting the establishment of the Olive Downs Coal Mine. Works included the construction of primary access roads, ongoing maintenance grading, and large-scale topsoil

stripping and stockpiling across multiple areas of the site. HPR also constructed a high-spec maintenance and workshop pad using UTS GPS-controlled placement and trimming to meet final design tolerances. 

The scope extended to major water infrastructure, including a 1.8 km mine-affected water drain and two storage dams with capacities of 280,000 m³ and 380,000m³, all built to GPS design specifications. HPR also constructed internal access roads using quarry-sourced gravel, delivering a safe and functional site layout. This project highlights HPR’s ability to deliver high-volume, precision civil works in active mining environments with reliability and efficiency.

Client: FKG Group
Timeline: 5 Mar 2024 – 8 Jul 2024

Scope of Works:

HPR was engaged to carry out the civil works for the construction of a new gas evaporation pond. The scope began with loading, hauling, and stockpiling topsoil from the dam footprint, followed by ripping and conditioning the pond floor using a CAT D10T dozer and a water truck. This preparation was crucial to ensure the pond's structural integrity.

Next, suitable material was loaded, hauled, and placed from the dam area onto the wall construction area. The material was placed in thin layers and treated with lime to achieve the optimal moisture content (OMC), in line with the technical specifications. Finally, topsoil was placed on the completed walls to ensure final stabilization and promote long-term environmental health. HPR’s precise execution of the project was key to meeting all technical requirements and ensuring the pond’s successful construction.

Client: Thiess Pty Ltd
Timeline: 25 Nov 2023 – ongoing

Scope of Works:

Heavy Plant Rentals (HPR) was engaged by Thiess Pty Ltd to deliver a comprehensive package of civil works and infrastructure construction at an operating mine site. The scope includes the construction of multiple drainage systems for clean and contaminated water management, incorporating sediment ponds, overflows, and controlled release points, all built to GPS design tolerances. HPR

also delivered civil works for the fuel farm and storage facilities, including access roads, drainage, pipeline alignments, and pad foundations. 

Additional works included the formation of key operational infrastructure pads for mine support services such as the HME workshop, HV and LV wash pads, autonomous calibration area, and tyre handling zones.

HPR has also been responsible for regular maintenance grading of gravel roads, construction of several on-site car parks, and the installation of twin 1800mm culverts

beneath the mine’s main haul road—delivered as a staged day and night operation. The project highlights HPR’s ability to provide safe, responsive, and specification-compliant delivery across a broad range of mining civil infrastructure tasks.
