Scope of Work:

Cut and Fill Excavation in Seven Hills: Precision Groundworks for a New Learning Facility

Dicks Diggers was entrusted with the critical task of preparing the site for a new building at Seven Hills Public School. Our team carried out extensive cut and fill excavation in Seven Hills, as well as detailed excavation, piling, and service trenching, over a 6,000 m² area. This project required precision, safety, and strict adherence to local regulations. By expertly managing each phase of the earthworks and groundworks, we created a stable foundation, enabling the school’s expansion project to progress efficiently.

Project Overview: Cut and Fill Excavation in Seven Hills

The Seven Hills Public School expansion project required comprehensive site preparation to support a new building that would enhance the school’s capacity and facilities. The project scope included:

1. Cut and Fill Excavation

2. Detailed Excavation and Piling

3. Service Trenching

Each phase was vital in preparing the land for construction, ensuring that the site was level, stable, and ready for future development. Our experienced team followed rigorous standards to complete each phase with precision, laying a strong foundation for a seamless construction process.

Project Scope and Key Objectives

The cut and fill excavation in Seven Hills was an extensive operation, involving a range of services essential for a successful building foundation. Key objectives included:

1. Cut and Fill Excavation

The project required extensive cut and fill operations to achieve the necessary levels across the 6,000 m² site. This process involved moving substantial amounts of earth, balancing soil cut from higher areas with fill to lower sections.

2. Detailed Excavation and Piling

Following cut and fill, our team performed detailed excavation and installed piles to ensure the site was adequately stabilized, meeting structural requirements for the new building.

3. Service Trenching

The site also required service trenching for utilities and drainage. This phase was essential in providing the new building with access to necessary services while preserving structural integrity.

Our Approach to Cut and Fill Excavation in Seven Hills

Dicks Diggers applied a structured approach to each aspect of this project, emphasizing precision, compliance, and safety. Here’s an overview of our methodology:

1. Initial Site Assessment and Planning

Before starting excavation, our team conducted a comprehensive assessment to determine the existing site conditions, including soil composition, slope, and geotechnical requirements. With this information, we developed a detailed plan to address the specific cut and fill needs, ensure proper soil compaction, and maintain safety and regulatory compliance throughout the project.

Initial planning steps included:

-Topographical Surveying: Mapping the site to identify cut and fill zones and estimate soil volumes.

-Geotechnical Testing: Analyzing soil stability and classification to inform excavation and compaction techniques.

2. Executing Cut and Fill Operations

The cut and fill phase was a core component of the project, involving substantial earthmoving to level the site for construction. By balancing soil from cuts in high areas with fills in low areas, we minimized the need for importing or exporting materials, achieving efficient, cost-effective earth redistribution.

Our approach to cut and fill included:

– Precise Earthmoving: Using GPS-guided equipment to execute the cut and fill plan with high accuracy.

– Soil Stabilization: Compacting soil in fill areas to meet density standards, ensuring long-term stability.

3.Detailed Excavation and Piling

After the primary leveling, we conducted detailed excavation to prepare for foundation and utility work. This phase required precision to meet structural requirements and depth specifications, ensuring a secure base for the new building. Additionally, piling was carried out to enhance stability in areas with softer soil, providing additional support for the construction foundation.

Key elements of this phase included:

– Laser-Guided Grading: Ensuring even grading and exact depths across the site.

-Secure Piling: Installing piles in designated areas to support structural load requirements.

4. Service Trenching for Utilities

The final phase of the site preparation involved service trenching, laying the groundwork for essential utilities such as water, electricity, and drainage. This stage required careful planning to ensure trench placement would not compromise site integrity while allowing easy access for utility installations.

Our trenching process included:

– Safe Trench Excavation: Ensuring compliance with depth and width standards to prevent collapse.

– Clear Utility Marking: Labeling each trench for future access, helping prevent damage during construction.

Challenges and Solutions

Large-scale cut and fill excavation in Seven Hills presented several challenges, each requiring innovative solutions and thorough planning:

– Balancing Cut and Fill Volumes

Achieving balance between the cut and fill areas is critical in reducing material waste and managing costs. Our team performed careful volume calculations to avoid excess soil export or import, optimizing material use on-site.

– Ensuring Soil Stability and Compliance

Site stability is paramount, especially in a school setting. We used geotechnical testing to identify potential risks, while compacting and stabilizing soil in compliance with Level 1 supervision requirements, ensuring a solid and safe foundation.

– Minimizing Disruption to School Operations

Working on an active school campus requires strategies to reduce noise and limit disruption. Our team coordinated work schedules to minimize impact, particularly during peak hours.

Results and Project Impact

Upon completion, Dicks Diggers successfully delivered a site that met all structural and safety requirements, supporting the development of a new building at Seven Hills Public School. Key outcomes included:

1. A Level, Stable Site Ready for Construction

With careful cut and fill excavation, detailed grading, and compaction, the site is now level and stable, providing a dependable foundation for the school’s new building.

2. Compliant and Safe Service Trenches

The service trenches were accurately placed, following safety standards to provide essential utility access while ensuring structural integrity.

3. Efficient, Environmentally Responsible Earth Management

Our cut and fill operations minimized the need for imported materials, reducing environmental impact and project costs.
