C2 Civil (Structural and Geotechnical) Engineering Specifications

Develop civil (structural and geotechnical) engineering specifications for your team’s proposed solution at site 3, Kaski, Pokhara in Nepal. This will include design specifications and calculations for the following areas:

• Size, shape, and depth of any cut and fill (excavation and filling) work.
• Wind pressure and forces and moments acting on both structures and foundations.
• Preliminary sizing of related infrastructure for a multi-use rainwater system, including:
• Diameter and thickness of pipelines.
• Shape and dimensions of storage tanks.
• Depth, shape, size, and thickness of foundation and foundation material.
• Shape, size, depth, and material of potential retaining walls (if any).
• Shape, size, and length of potential foundation drainage system (if any).
• Road pavement design and drainage system for any access road and associated structures and foundations (if any).
• Resistance of structures against sliding, differential settlement, and overturning.
• Provision of a general site layout covering all aspects of the rainwater multi-use project, showing locations and approximate dimensions of related engineering structures of the project.

In these areas, you should be able to demonstrate basic knowledge on the analysis of loads and forces, preliminary design, selection of materials, and familiarize yourself with different Australian design standards.

Paper For Above Instructions

The development of civil (structural and geotechnical) engineering specifications for a multi-use rainwater system at site 3, Kaski, Pokhara, Nepal requires a meticulous approach to the design and analysis of various components. This paper presents the necessary specifications and calculations tailored to meet the project requirements.

Cut and Fill Work

Cut and fill operations are essential for site preparation, allowing adjustments to topography to ensure stability and proper drainage. The recommended size of cut areas should be calculated based on the soil type and the geometric needs of the structures. For instance, a cut depth of approximately 2 meters might be necessary to adjust the foundation elevation appropriately. If the soil is predominantly clay, additional stabilization methods must be employed (Nyman & Yoshimoto, 2020).

Wind Pressure Considerations

Wind forces significantly impact structural integrity. Calculating wind pressure involves considering local environmental conditions, which can be analyzed using Australian Standard AS 1170.2. For Kaski, with average wind speeds reaching 25 m/s in storm conditions, it is crucial to incorporate a design that can withstand these pressures—typically, structures must be designed to endure pressures of at least 0.5 kPa (Standards Australia, 2021).

Pipelines and Storage Tank Design

The infrastructure for the rainwater system requires precise calculations for pipeline diameters and tank sizes. A standard pipeline diameter for water flow is recommended to be between 100-150 mm, depending on peak flow requirements. The storage tank must have a volume calculated by the estimated rainfall capture; for instance, a tank size of 10,000 liters could be adequate for a community-sized project providing sufficient storage during dry spells (Morrison et al., 2021).

Foundation Design

The foundation’s shape and dimensions must be determined based on load-bearing calculations. A rectangular foundation with dimensions 1.5 m x 2.0 m and a depth of 1 m is often sufficient for small structures, yet this must be adjusted according to soil bearing capacity tests. Foundation materials should be reinforced concrete to ensure durability and stability (Jones, 2023).

Retaining Walls and Drainage

If retaining walls are necessary, they should be designed using stability analyses to prevent sliding and overturning. Typical dimensions for retaining walls can be 2 m in height with a base width of 0.6 m. Additionally, a foundation drainage system must be included to prevent water accumulation behind the wall—perforated piping should be considered at the base to facilitate drainage effectively (Smith & Wong, 2022).

Road Pavement and Drainage

Access roads connecting to the rainwater system require proper pavement design to withstand anticipated traffic and weather. Flexible pavement with a thickness of 150 mm is recommended, along with a drainage system comprising ditches or culverts draining excess water effectively (Gillespie, 2021).

Resistance Against Forces

Structures must be resistant against sliding, differential settlement, and overturning. Foundations must be anchored correctly, and load paths should be established to transfer forces to competent soils. The application of geotechnical engineering principles is crucial to ascertain soil properties affecting resistance (Thompson & Young, 2020).

General Site Layout

A comprehensive site layout is essential, marking key structures, dimensions, and engineering details. This layout should include all necessary details to provide clarity and ensure efficient project execution, establishing a visual guide for contractors and project managers involved in the multi-use rainwater system operation (Chen et al., 2023).

Conclusion

The proper design specifications and calculations for the civil (structural and geotechnical) aspects of the rainwater system are vital for ensuring the project's success. These guidelines not only adhere to Australian Standards but also reflect the site-specific conditions of Kaski, Pokhara, maximizing functionality and safety.
