MAD3 Engineering (formerly McDowall Affleck) designed all the earthworks, retaining walls, roads, drainage, sewer, water reticulation, underground power and communications. The 119 lot subdivision was developed over 3 stages with shared drainage with the adjacent subdivision.

Scope Of Work

• Design and documentation of earthworks
• Design of all roads, drainage, sewer and water reticulation
• Structural design of all retaining walls
• Tender and superintendence of 24 lots on adjacent subdivision utilising a shared drainage system.

Project Challenges

The site was steep, constrained by four neighbours with existing high retaining walls, requiring tying into existing levels to ensure that the adjoining sites could be developed in the future. Changes to planning layouts also required more complex earthwork designs with high retaining walls.

How We Managed This

Throughout the project MAD3 engaged with our client to develop design plans that accommodated for future stages whilst incorporating the existing retaining walls along the western boundary.

Value Engineering

MAD3 were able to be responsive to the project across the duration through utilising our structural team to deliver a cost-efficient design to maximise the return for our Client.
