Core Services

Together, we deliver.

Unlike other construction companies, our vertical integration means we hold accountability for keeping the brief and budget together, managing risk throughout the entire project lifecycle.

Delivering solutions, The Calder Way.


The Calder Way is how we deliver world class outcomes for our clients on time, on budget, and to the highest of standards.

What sets us apart is our unwavering commitment to innovation, sustainability, and client satisfaction. By leveraging cutting-edge technology, sustainable practices, and transparent communication, we ensure that every project we undertake exceeds expectations and leaves a lasting impression.

Early Contractor Involvement (ECI)

ECI contracts are becoming a popular model to provide a collaborative approach to complex or high risk projects. ECI provides a collaborative team time to gain an early understanding of the contract and design requirements to enable value engineering.

Our team has been involved in many ECI contracts providing extensive experience in creating true value at this critical stage.

Design Management

Our team’s deep knowledge of construction materials and methodology offers the benefit of a ‘whole-of-project’ perspective from the outset, ensuring a cohesive, collaborative and enjoyable client experience.

Our engineers and BIM managers intimately understand the design process and work to bring all parties on to the same side of the table.

Building Information Modelling (BIM)

BIM extends beyond traditional 3D modeling to include additional dimensions such as 4D and 5D BIM that provide richer data and insights throughout the project lifecycle.

Viewing projects in virtual and augmented reality throughout the design and construction phases allows the front footing and resolution of issues early – saving you time and money – without compromising on delivery excellence.

Having a local company with everything under one roof from design to manufacturing provided a seamless and streamlined build within budget and to a tight timeframe. The quality of work was outstanding, as was their attentiveness, attitude and performance.
