"Throughout the project, Callen Constructions demonstrated exceptional professionalism and expertise. They were able to resource the main occupation efficiently, ensuring that all tasks were completed within the designated timeline. The quality of their work was consistently of a high standard, reflecting their commitment to excellence and attention to detail."
"Callen Constructions are a highly proactive subcontractor to work with, primarily driven by director Grant Callen, who has a very solution driven mindset. As a result of Callen Construction’s commitment to the larger project goals and being able to work on near 18 individual culvert locations simultaneously, Seymour Whyte was able to achieve majority of the earthworks and pavement construction scopes prior to the anticipated autumn/winter weather impacts of 2024; this was a major milestone in seeing such an aggression risk mitigation strategy delivered to its full fruition.
