The Difference



The Company

Core Civil Construction Incorporated has evolved from the roots of Tweedale Sewer and Water Ltd., founded in 1998.

Core remains committed to uncompromising safety and worker training. Management is active in safety training and monitoring, scheduled equipment maintenance, and importantly, communication amongst our clients, our partners, and our workers.

Most of our employees have spent their working lives in heavy construction. Core is proud to give respect and guidance to all employees. This is our COMMUNITY. It is strong and flexible. Core will continue to provide best practices and safety to this impressive group of people. Core Civil Construction is a refreshing place to work, and we are committed to embracing new approaches to heavy civil construction.

CORE considers growth to be an internal mechanism. To train and strengthen our existing team, to provide the best equipment to suit a project, and to streamline our organization in the office and the field. At the core is RIGOR. Management seeks innovation in the office. Our team is always looking for new tools to schedule, manage and perform work safely with quality workmanship. These same tools assist greatly while facing adverse weather and working conditions, difficult installations and pandemics.

Our experienced team is skilled in managing all aspects of a project and brings their training and professionalism to owners, builders and the community as a whole. Management continually gathers feedback from the team and provides the latest technology and tools. PRECISION results from this communication and training. This is key in heavy construction; where specifications, workplace demands and the market place are constantly evolving.



Core Civil Construction trains our employees in a number of different health and safety courses. Some of these courses include WHMIS, Traffic Control Book 7, First Aid and CPR, Confined Space entry, Trenching & Excavation: Competent Person Training and Fall Protection Working at Heights. Every winter we renew and revise our health and safety policy, updating where required. We have also put strict Covid Protocols in place. Several of our team members have been working toward their Certificate of Recognition (COR) accreditation program to bring Core Civil Construction up to the national standard in health and safety.
