We are extremely excited to join forces with Aedifice Property Group in their groundbreaking Kohe, situated in the vibrant town of Pukekohe. CIVIX planners, engineers and surveyors have been involved since identifying the potential of the property for a private plan change.

This ambitious project is set to redefine residential living, introducing a captivating micro-community of over 700 homes infused with a multitude of sustainable initiatives. We are proud to share that we have submitted the necessary resource consent for the initial phases, which will encompass the construction of the first 200 homes with construction slated for completion in the latter half of 2026. We eagerly anticipate the transformation and growth of this project.

The Challenge

The project presented several significant challenges due to its large scale and the absence of existing infrastructure on-site. The key challenge was the creation of a comprehensive infrastructure network to service the development, starting with the installation of extensive public utility systems for the first 200 homes. This required careful planning and execution to meet stringent engineering standards and minimize costs, all while ensuring resilience to flooding in a flood-prone area.

The specific infrastructure requirements included:

• 303 storm drain pipes (4.4 kilometres)
• 89 sanitary sewer pipes (3.3 kilometres)
• 310 water supply pipes (5.7 kilometres)

In addition to meeting council engineering standards, the design had to ensure:

• Proper pipe cover and minimum clearances between pipes
• Precise gradients for the effective flow of water, sewage, and stormwater
• Mitigation of risks such as structural conflicts and design errors, particularly those that could arise during construction
• Flood resilience, given the area's susceptibility to future flooding events

The solution also needed to balance capital expenditure (CAPEX) and operational expenditure (OPEX) effectively, optimizing resources while reducing costs without compromising quality or compliance.

Technology in Action

CIVIX utilised the Allsite.ai platform to streamline and enhance various stages of the design process. The platform's suite of tools offered significant time and cost savings, as well as improved accuracy and efficiency across multiple aspects of the project:

Scheme AI 1.0

The Scheme AI 1.0 tool automates the generation of easements and associated tables with a single click, directly matching the servicing design. What would otherwise be a manual, time-consuming process is now completed almost instantly.

Cut Fill AI 1.0

The Cut Fill AI 1.0 tool simplifies complex tasks such as:

• Semi-Automatic Building FFL Generation: The tool generates the set Finished Floor Levels (FFL) and step-downs around buildings seamlessly into the TIN surface.
• Bulk Cut and Fill Estimation: It accurately estimates cut and fill volumes, factoring in both pavement and building foundation designs.
• Erase and Replace Function: This feature allows for quick updates to the TIN surface for specific areas of interest, ideal for large-scale projects where development occurs in phases and at different timelines.
• Schedule of Quantities (SoQ): The SoQ tool estimates material quantities required for the design, streamlining procurement and ensuring accuracy.

Service AI 1.0 & Tuflow Flood Modelling

By integrating Service AI 1.0 with a semi-automated Tuflow flood modelling engine, the platform significantly enhanced design and risk management:

• Automated Pipe Network Design: Service AI 1.0 automatically designs the entire pipe network, ensuring compliance with engineering standards such as invert levels, clearances, and grades.
• Cost Optimisation: The AI-driven platform optimizes pipe size and routing, minimizing both capital and operational expenses (CAPEX and OPEX) by reducing material and installation costs.
• Built-in Quality Assurance: The system detects potential design conflicts, such as pipes positioned too close to retaining walls, and automatically suggests corrective actions, ensuring design integrity.
• Detailed Outputs: Service AI 1.0 generates comprehensive outputs including pipe long sections, capacity tables, and plan views that align with Auckland City Council standards, reducing the need for manual drafting.
• Trench and Excavation Management: The platform calculates trench volumes and recommends appropriate excavation methods (e.g., shoring or benching), improving coordination between developers and construction teams.

TuFlow Flood Modelling

The semi-automated Tuflow flood modelling engine ensures the design is resilient to future flood events. This capability plays a crucial role in creating more sustainable, flood-resistant developments.

Client Feedback

The CIVIX project engineer praised the efficiency of the Allsite.ai tools, stating, “Iterations of the servicing design took less than an hour to complete. The system ensured that every pipe invert met the required standards. It automatically resolved clashes with other services and proposed compliant design alternatives. The 3D servicing design updates promptly with each change to the design surface, saving countless hours compared to traditional methods. Allsite.ai not only detected potential issues but also provided solutions, ensuring the final design was optimized for both cost and performance."

Benefit & Results

The integration of Allsite.ai technologies in the KOHE delivered significant time and cost savings, optimized design accuracy, and enhanced project efficiency. Key benefits included:

• Time & Cost Savings: Automated tools like Scheme AI 1.0 and Service AI 1.0 reduced design time from days to under an hour, cutting both CAPEX and OPEX by optimizing pipe sizing and routing.
• Improved Accuracy: AI-powered tools eliminated design conflicts, ensuring precise and conflict-free infrastructure layouts that met council standards.

This innovative approach has set a new benchmark in residential infrastructure development, ensuring that the KOHE project will not only provide high-quality homes but also be built with the utmost efficiency, sustainability, and resilience. We are excited to see the positive impact it will have on the Pukekohe community for years to come.
