McMillan delivered five rigs, which drilled many thousands of metres of core. They delivered quality core, and also undertook some in-situ testing. They managed subcontractors and their set-up was above normal standards for safety and environmental protection. They were helpful, communicative and flexible, which made the management of the ground investigation easy. I was very happy with their physical work and their open, collaborative approach to project management. I would not hesitate to recommend them.
