Plant Hire

With over 45 years of experience working in many diverse areas of the civil construction industry LR&M Constructions Pty Ltd (LRM) have developed its resources to meet the needs of our clients for any civil construction project in a reliable and efficient manner.

We continually develop our services to meet the demands of the civil and mining sectors and the ever changing and complex expectations of our clients.

Our clients expect us to provide three key requirements when utilising our services:

  • Quality Service
  • Reliable Equipment
  • Competent Operators


Utilising the core skills of LRM, Chamberlain Investments progressively launched into land development projects primarily in the northern region of Adelaide. The success of these development activities led to further involvement with major development companies such as Hickinbotham, AVJennings and Devine Communities as either joint venture partner or with sales /marketing agreements.

LRM as the principal contractor provided significant construction expertise, and quality performance resulting in the successful delivery of these projects.

Today, Chamberlain Investments have under its control or as a holding company the following entities:

  • Opthummell Pty Ltd
  • Kentia Developments Pty Ltd
  • Adelaide Land Development Projects Pty Ltd
  • Graften Pty Ltd
