A construction survey is used to establish or mark the desired position of building corners, roads, sidewalks, or utilities, that the engineer has designed. Particular attention is made to ensure the building does not encroach or overlap into or over the designated setbacks, easements, or property line. These points are then “staked out” onto the actual property to indicate the location of the improvement, generally flagged or painted lathe, stakes, or rebar are used.

TOP THREE ADVANTAGES
Build pre-plan
Site survey and monitoring of excavations for 3d modeling
Progress measuring
Create 3d replicas of buildings, contractor and project liability on time
Share data and accuracy are sure
Share data with remote engineers and other key stakeholders
CHALLENGES
- Location progress monitoring: Daily or even hourly flights can be carried out to document and digitize locations.
- Structural inspection: Inspections can be carried out easily using a drone platform with a high zoom camera like the Z30.
- Site survey: Modeling elevation, centimeter level precision survey class mapping capabilities.
- Stakeholder presentations: Create stunning presentations from different perspectives from high resolution video and photo taking.
- Building Information Management (BIM): Digitize assets with a real life dimension.
SOLUTIONS
- Frequency: Drones can be used to collect the latest data regularly with minimal costs and disruptions to operations.
- Data quality: Sensor technology that allows operators to collect high quality data from Lidar and other camera sensors. In addition, data obtained from areas that are difficult to obtain or access can be obtained at the site or in the office and shared with stakeholders.
- Data analysis: Data can be processed into 3D photogrammetry or point clouds and convert it to DEM or DSM, which can be further analyzed to extract volumetric calculations, stocks, rise models etc.
- Safety: Operators can collect data from a safe place, increase safety by up to 55% and reduce the need for humans to move to often dangerous environments.
- Efficiency: Drones, sensors and other survey tools can collect data from a wider and more efficient area from a person.
