Subsurface Utility Mapping using the Spar 300 System by Optimal Ranging, Inc.

PROBLEM: The need for accurate, 3D geospatial locations of utilities has become vitally important from a planning and safety perspective. Inaccurate utility location data causes unnecessary project delay costs due to damaged facilitates and can be a major safety concern.

SOLUTION: DAAR Engineering and the Spar system. DAAR has been engaged in a solution that can accurately locate and survey these utilities with elevation data without excavation.


DAAR is established as an industry leader in construction staking from our vast experience in large scale commercial construction projects and municipal construction staking. We are responsible for placement of building on-site, placing utility alignments, establishing horizontal and vertical control lines, coordinating between the design team and the contractor, as well as quality control through project completion.
