Focused on Innovation and Results

In 1937, Calvin, Giordano & Associates, Inc. (CGA) created its Surveying and Mapping Division. It was among the three main divisions upon which CGA was founded and is still continuing to grow today.

Fully Equipped for Every Type of Survey

Many surveying and mapping methods have been used over the years, and CGA continues to stay at the forefront of technologies available so that we can provide the most accurate, safe and cost effective services to our clients.

CGA is one of the first firms in Florida to acquire the state-of-the-art laser scanner, the Leica HDS ScanStation C-10. The ScanStation takes a virtual snapshot of a site with a level of detail that was previously impossible; sites such as ceilings, undersides of bridges, elevated pipe racks, tall facades, columns and towers. By collecting millions of data points in a 360° horizontal and 270° vertical field of view, field crews can survey a site once and have a permanent record of all the visible items on file. Three dimensional visual images and virtual walk-throughs can be prepared for use in litigations, client presentations or commission meetings. Because the data is collected entirely by the scanner, the elimination of a rodman greatly reduces safety concerns.

CGA uses a slurry excavation system, VaXcavator, to expose existing underground utilities. Operated by a field survey crew, it allows us to obtain the sub-surface information and the horizontal and vertical locations required for design, while realizing cost and time savings.

Finally, our Hypack software with Odom sounder enables us to offer hydrographic surveying services. By integrating with our Trimble GPS units, the equipment creates a three-dimensional model of the body of water being surveyed resulting in significant savings for our clients.

Well-Charted Process, Well-Executed Projects

The process we employ is equally as important as the equipment we deploy. All survey requests are assigned to a licensed surveyor and mapper who acts as project manager. Data is collected electronically using total station instruments and is downloaded into our computer system for analysis and processing. Our computer technicians take the data and create the final product. After a Quality Assurance/Quality Control review, the final product is delivered to the client.

CGA offers the services, staff and technology to ensure every survey project is executed successfully and to our clients’ satisfaction.
