Major Construction

The Holmes Electric major construction team has developed an expertise in Commercial, Residential, Government, Military, Industrial, Medical, Data Centers, Office, Hotels & Recreation, Renovation and Design-Build projects. We work with contracts ranging from fully designed to starting at conception in Design-Build projects. Such projects are extremely complex in their electrical requirements and management demands, but the professionals at Holmes Electric consistently deliver high quality projects on time and on budget. Through continuous education and innovation, we develop the knowledge and tools necessary to best serve our customers in an ever changing technological world.

The major contracts division specializes in larger budget and longer duration projects. Our team works with you to establish a baseline project budget throughout the preconstruction and construction process. From the moment we are awarded a project, we identify project milestones and start planning for a successful project right away. It is essential that materials arrive on time, we identify long-lead items early and work with our vendors to maximize transparency to all project stakeholders and to achieve final delivery to the client. Throughout our projects, we use various tools to help us plan weeks ahead and to identify potential issues early so we can manage risks. We love a project where ‘everyone wins’, this will always be our goal.

We have a range of expertise within our team and pride ourselves on the training and wisdom shared to future company leaders. Our team meets weekly to discuss current projects, systems and their efficiency, and for leadership training. We are constantly sharpening our ability to better meet the needs of our customers and teammates.
