Sitework is the critical first step in the construction process. Proper site preparation and protection set the stage for the rest of the project. Colantonio has the experienced crew and the equipment to expertly lay the groundwork to start your project off on the right foot. We also have the flexibility to schedule the work as needed or even step in and assist a struggling subcontractor, ensuring your project stays on schedule.

“One of the benefits of Colantonio self-performing the sitework was that it allowed for accelerated teamwork to resolve site-related issues. Site contractors are the first ones in and last ones to leave and, since they are using their own forces, that allows greater control of the schedule. They also did an excellent job with vertical communication among their subcontractors.”
