About This Project

SurveyWorx were commissioned to manage & deliver the Rights of Light (ROL) Survey Specification, working in collaboration with the Architectural & Design Teams who would lead the redevelopment across the Project.

We would supply Survey Data & Graphical Information necessary to produce an accurate understanding of any potential loss of daylight/sunlight resulting from a proposed new development.

The Booth Place site comprising 7 Floors (Ground to Level 06) located in London, would be demolished & redeveloped to include additional Housing to the area feeding into a wider regeneration masterplan. The Project would see the incorporation of a Sky Garden & Residential Terrace on the 6th floor, with associated shared amenity spaces & landscaping & cycle parking, ancillary spaces & refuse storage incorporated within the Scheme.

Survey Methodology & Project Delivery

Using a combination of the latest integrated Robotic Total Stations, GNSS, HD Laser Scanning Technology & “Robust Survey Methods” to capture & verify accurate Survey Data, the Survey Specification was delivered both efficiently & cost effectively within the allocated timescales.

Establish Control Network Framework

Primary Survey Control was established using Total Station, GNSS & Precise Levelling. PK/Mag Survey Nails with Survey Markers were drilled/fixed into hard standing surfaces with Station Description Sheets completed to aid with follow-on Construction/Engineering Works.

Data Acquisition/Capture

Data was acquired/captured using a combination of Robotic Total Station (1”) & HD Laser Scanning Technology. Survey Data was captured from Street Level & from surrounding Roofs to ensure adequate level of detail was captured.

Scan Data Post-Processing

Point Cloud Data was Post-Processed within Leica Cyclone Software to produce a fully Registered/Coordinated Point Cloud, referenced to the Site Control Network using Secondary Control Coordinates observed from Primary Control established at street level. Post-Processing/Registration was completed using a combination of Target-Based Registration & Cloud-to-Cloud Registration.

Quality Assurance (QA/QC)

Quality Assurance procedures were completed with a Point Cloud Registration Report exported to highlight registration accuracy. Registration was a success with an average error of +/-2mm between individual Point Clouds.

Coordinate Reference System

Survey Data related to the OS Network OSGB36(15).

Delivery & Output

The final Drawing Package included; Massing Model & Elevations 2D AutoCAD & PDF. All Drawings were passed through Quality Assurance prior to final delivery.
