LITIGATION SUPPORT

Bear Flag’s cross disciplinary expertise in civil engineering and land surveying brings fresh and inventive perspective into legal matters involving:

Legal teams benefit from our 3D visualizations and exhibits demonstrating the facts based on state of the art data acquisition techniques and guided by courtroom tested experts with narrative flair and fortitude.

SURVEY

At Bear Flag Engineering our professional land surveyors and support personnel are talented and versed in the legal and technical aspects of the profession. We are engaged daily in legal research, resolving boundary discrepancies, boundary dispute litigation support, counseling on the meaning of boundary and easement legal descriptions, and land divisions. We are also technically versed in conducting detailed as-built, topographic, forensic and monitoring control surveys utilizing state of the art equipment and instruments, including such tools as high precision satellite positioning receivers, 3D laser scanners, mobile LiDAR scanners, Unmanned Aerial Vehicles (UAV’s), multi-spectral cameras, as well as the occasional tape measure, plumb bob and sledge hammer. Our land survey teams bring the experience of the site to you.

ENGINEERING

Encompassing a broad range of services, our civil engineering and technical expertise spans from water sourcing and natural resource valuation through conceptual and detailed design of critical site infrastructure.

Defining the project scope begins with the central idea, the objective. At Bear Flag Engineering, we help our clients formulate their ideas into a comprehensive course of action.
