Survey Specialty:

Surveying for Industrial, Commercial,

and Heavy-Civil Projects

Industrial projects demand attention to detail, achieving tight tolerances, following strict safety guidelines, and meeting tight deadlines. SDA's survey technicians are skilled and experienced in this field and able to exceed the requirements.

SDA has well-established procedures for a variety of tasks. For instance, we are the leading firm for crane rail surveys and are expert in analyzing a crane runway for adherence to CMAA or other specifications to evaluate eccentricity, straightness, span, and elevation. Our reports are clear and easy to decipher, clearly stating whether a measurement meets or fails the evaluation criteria. We have developed similar well-documented procedures for other types of tasks, and rely on our experience to hit the ground running on any project involving industrial or heavy-civil construction.
