Who are we?                             Phil Caldwell resumé                Vince Sunter resumé

The principals of Calsun are Phil Caldwell and Vince Sunter, degree mechanical engineers with extensive experience in mining and medium - heavy industry. They have worked together for many years. They are capable multi-discipline project managers who have been taking the lead role in major projects for a combined period in excess of 40 years, developing a very strong project culture to routinely satisfy all stakeholder requirements. No lost time accidents have occurred on any project under their control.

Calsun's excellence in Project Management was recognised at the 2003 Australian Institute of Project Management Achievement Awards night when Calsun was selected as one of the eight NSW Finalists in front of over a hundred other project managers and leading NSW companies.

The original Company was formed by Phil Caldwell in 1989 to perform general coal industry engineering and project work before that Company expanded into highwall and underground development mining and mining equipment support. In 1997 Calsun was formed by the current principals to focus on the performance of engineering project work, with some specialist engineering and maintenance services also to be provided. 

Calsun provides viable economical solutions for materials handling and processing applications, often including refurbished second hand equipment to reduce cost. Core expertise is in the coal mining industry but with considerable experience in the steel, minerals, aluminium, grain, glass, rail and transport industries. A track record of executing projects safely, economically and efficiently is assisted by effective computer based project control and risk management systems developed to ensure the delivery of all works on time and budget.

Due to the performance of a range of significant projects excellent commercial relationships are in place with many key industry suppliers. These allow the Company to securely undertake large projects on a fast track basis and ensure the timely delivery of equipment and full back-up support as needed. The Company is able to easily perform multi-disciplinary turnkey project work to $10M including all investigative engineering, design, earthworks, civils, mechanicals, structurals, sitework, electricals and commissioning. Funding is readily secured to execute larger projects and considerable experience entering into Joint Venture arrangements with large public Companies exists for very large infrastructure development projects where appropriate.

Project work undertaken includes reclaim and stacker systems, truck & rail loading / receival systems, plant and overland conveyors, loop take-ups, bins & hoppers, ore receival & crushing, feed systems, coal preparation plant modification and upgrades, sizing systems, mining development, general infrastructure, grain silo conveyors etc. Work performed has included extensive experience with underground conveyors and general mining equipment.

Full materials handling maintenance and management contract services have also been provided very successfully. Autonomous maintenance management of select or complete materials handling and processing systems can be offered to reduce overall operating costs.

Due to the extensive experience of Calsun's principals fast reliable performance is ensured whilst minimising overheads and providing the most economical outcome at all times. All QA systems and documentation necessary for the proper and effective carrying out of the offered projects and services efficiently and safely are in place.

We would be happy to assist any customer to quickly find the most economically viable practical options to assist with their materials handling or general plant upgrade needs.
