Major Estate Subdivisions

Surveys for estate subdivisions in South Australia

The team here at Sawley Lock O’Callaghan were engaged to provide project management surveying and civil engineering services for a multi-staged business and residential estate on the outskirts of Mount Gambier. The first part of the project involved the initial surveying of the subject land to facilitate site planning for the re-zoning application. Followed by the preparation of the overall concept plans for 47 light industrial allotments and the subsequent development of a further 290 residential allotments.

The project has been managed by Damian Brogden over the 8-year period of activity.

The services we provided for the Light Industry Estate included;

  • Project management including supervision of construction contracts, budgets, and financial arrangements and coordination of installation of utility services
  • Overall engineering, cadastral, construction set-out and as-constructed surveys
  • Civil engineering design including arrangement and engagement of specialist geotechnical and hydrology consultants
  • Project Management for the design and construction supervision of road alterations for the major intersection at the corner of the site to facilitate large vehicle movements to and from a Bunnings retail facility and including the arrangement of necessary service upgrades to the site.

I recently completed my third subdivision with Sawley Lock O’Callaghan. I have returned each time because the service is exemplary. I encountered many problems during the developments, yet the team at Sawley Lock O’Callaghan were able to liaise with Councils and other professional bodies to provide a solution on each occasion.

It is such a change to deal with people who are professional, helpful and pleasant. Of the four times we have used Sawley Lock O’Callaghan, it has always been the same, and it happens all too rarely these days. It was very much appreciated

I engaged Sawley Lock O’Callaghan for my subdivision project in 2015. They were fantastic to work with – diligent, thorough, intelligent, insightful, and tireless. They were extremely professional. As the project manager for my project, Max was always willing to listen yet never shy to give honest feedback.
