Services
Land Surveys
GUIDA's foundational service includes boundary surveys and cadastral mapping that comply with California's strictest legal standards. Our licensed surveyors use precise instruments and title research to establish property lines and resolve encroachment issues for residential, commercial, and municipal clients. With three decades of localized experience, we deliver accurate mapping that forms the basis for all subsequent development projects.
LiDAR Services
Our LiDAR technology captures detailed 3D point clouds for as-built documentation and construction monitoring. This non-invasive method generates precise digital elevation models that support infrastructure maintenance planning and complex engineering designs. The technology significantly reduces field time while maintaining sub-centimeter accuracy for critical transportation and utility projects.
Construction Surveys
GUIDA's construction surveyors provide layout staking, as-built verification, and monitoring services that align with project specifications. We use GPS/GNSS systems and robotic total stations to ensure dimensional accuracy during grading, utilities installation, and structure placement. Our services help prevent costly rework while maintaining compliance with Caltrans and local jurisdiction requirements.
Utility Surveys
We employ ground penetrating radar and electromagnetic detection to create comprehensive utility maps for project planning. Our surveys identify both metallic and non-metallic underground infrastructure, reducing excavation risks and compliance issues. Clients receive detailed as-built records that meet ASCE 38-02 standards for subsurface utility engineering.
UAV Services
Our FAA-certified drone operators conduct aerial surveys that produce georeferenced orthophotography and topographic models. UAV technology enables rapid data collection for large sites while maintaining survey-grade accuracy. This service supports right-of-way analysis, construction progress monitoring, and volumetric calculations for mining and earthwork projects across California.
