FROM ONE TRUSTED PARTNER
OUR COMPANY
All systems work together to ensure that CornerStone projects are completed
ON TIME & ON BUDGET
customer service
Many contractors claim they provide superior CUSTOMER SERVICE – CornerStone delivers:
Our job is to build strong foundations and systems. Our promise is to build committed relationships with our customers. For every single project, we aim to go above and beyond what is asked of us. We believe that satisfaction is only satisfactory. Our customers are why we are in this business.
value
Many contractors talk about VALUE – CornerStone delivers:
Advanced planning with Building Information Modeling (BIM) and Robotic Total Station Layout ensures significant productivity and accuracy increases. With better-coordinated designs, these technologies allow CornerStone to deliver with precision, a high quality product on time and on budget. We find solutions when others say it can’t be done.
speed
Many contractors strive for SPEED – CornerStone delivers:
Efficient and dedicated project management puts us out in front of projects to always meet deadlines and, more often than not, push the mechanical contractors. Advanced-level engineering and prefabrication in CornerStone facilities adds to the efficiency of installation. We challenge ourselves to stay ahead of the pack because of our dedication to deliver excellence on schedule. We simply don’t miss a deadline.
risk
Many contractors hope to reduce RISK – CornerStone delivers:
Through advanced planning, we discover potential problems before a single component is installed or a yard of dirt is moved. Valuing the pre-planning process trims labor costs, reduces callbacks and ensures the project is done the first time. Onsite, our project leaders are continually connected to us by computer and report changes immediately. Because we don’t miss anything, the entire project benefits. We believe that the more thought we put into the project before it begins, and the closer we monitor it while in progress, the better it becomes.
engineering and manufacturing
Our Virtual Design & Construction (VDC) team leverages cutting-edge technology to go beyond traditional drawings by precisely modeling individual components for accurate design and manufacturing. This virtual precision is seamlessly transferred to the field using our Robotic Total Solution (RTS), ensuring exact installation. Our precision manufacturing approach guarantees schedule compression, certainty of occupancy date, and stabilization of the project. By designing and manufacturing prefabricated plumbing and HVAC systems in-house, we leverage Lean Manufacturing principles backed by a rigorous quality control and quality assurance program, delivering exceptional results and reliability for all CornerStone One clients.
