Anselmi Ridge Project

Multi Lot Subdivision

Anselmi Ridge Limited is a residential subdivision in East Pukekohe where Birch delivered planning, engineering, and surveying services for stages three and four under complex site conditions.

Birch are proud to be associated with McConnell Property's Anselmi Ridge Development in East Pukekohe. 

We have had a long association with the site, having been involved in the original surveys before the development works commenced in 2006. 

Birch were engaged as the lead consultant in 2013 to manage stages 3 and 4 of the subdivision, working with McConnell Property's professional Development Managers to ensure the project was tracking according to budget and the planned timeline.  

We were responsible for all of the planning, engineering and surveying work associated with the development.  The final two stages of the development were completed in late 2015, and now presents a highly desirable living environment.

The subdivision presented numerous challenges to our team, including a shallow soil depth before volcanic tuff material was encountered.  This meant that services had to be designed to avoid where possible deep trenches into the tuff.  The sites were all benched (levelled) as part of the subdivision earthworks, creating good buildng platforms to allow a quick start to the building process.

During the process our relationships with the evolving Auckland Council and its subsidiaries were put to the test, with numerous policy changes during the project to contend with.  

The resulting development makes the best use of the available land and will be a desirable place to live for generations to come.

Frequently Asked Questions

What is involved in managing a multi-lot subdivision?

Managing a multi-lot subdivision can involve coordinating planning, engineering, surveying, earthworks, infrastructure, consenting, and project timelines across multiple development stages.

How can shallow soil affect subdivision engineering?

Shallow soil over hard volcanic material can make conventional trenching difficult. Infrastructure may need to be carefully designed to minimise excavation into the underlying material.

Why are subdivision sites benched during earthworks?

Benching levels sloping land to create more suitable building platforms, making construction easier while helping establish usable sites for future residential development.

How do site conditions influence infrastructure design?

Ground conditions, including soil depth and underlying rock or volcanic material, can affect the location, depth, construction method, and cost of roads and underground services.

What does a lead consultant do on a subdivision project?

A lead consultant coordinates key technical disciplines and project requirements, helping ensure planning, engineering, surveying, budgets, approvals, and development milestones remain aligned.

How can planning policy changes affect a subdivision project?

Changes to planning policies during a long-term subdivision can require the project team to reassess designs, approvals, and development strategies to maintain compliance with current requirements.
