Description
The Visual Arts facility is intended to be a centre of excellence and innovation for culture and learning. The town's new public building will include spaces for art, education, community spaces and leisure activities.
Mace were appointed project manager mid flight through the construction of the project, designed by architect Rafael Vinoly, and required a full as built survey of the structure, to undertake a survey of a building with such a complex geometry SES applied 3D laser scanning technology.
We decided to use 3D laser scanning for approximately 70% of the survey due to the various radial grid systems. Capturing a staggering 280million points the scan enabled us to
- Provide a 3D AutoCAD model
- Generate sections through complicated structural profiles with ease
- Create floor and reflected ceiling plans
- Survey high risk area's such as the roof without the need for high level access
- Minimise time spent in the field
- Eliminate the need for site re-visits
We found that the laser scanner has proved to be superior in this application. Please click on the link to view a 'fly through' of the building. http:www.sesltd.uk.com/laser-scanning.html
Description
Site Engineering Surveys Ltd carried out a survey of Park Place Croydon shopping centre on behalf of Bovis Lend Lease to enable the designers to plan the new development in the area. Our scope of works included for an elevation survey of the retained façades along George Street, North End and inside the Whitgift shopping centre.
Surveying these façades using traditional survey techniques would be extremely time consuming and costly. It was therefore decided that 3D laser scanning would be far more efficient in time and cost, with the added bonus that it would pick up all the intricate detail of the façade. 3D laser scanning allows the complete and accurate capture of 3 dimensional complex structures. The scanner used (Leica HDS 3000) can acquire up to 4000 points per second to an accuracy of 6mm over a 50m range. Any exposed surface can be remotely captured in minutes to form a dense and accurate "3D points cloud". Once the fieldwork is complete then each of the point clouds is mathematically linked together using common targets via the Leica Cyclone software. From the final point cloud a variety of deliverables can be produced from 2D plans, elevations and sections to 3D wire frames, models and visualisations.
From a safety point of view the instrument can be set up remotely in an area away from hazards. As it uses a non contact (class 3R laser) survey technique it is ideal for surveying inaccessible and potentially dangerous areas e.g. roads, rail and high rise areas. So it was therefore well suited to survey the high level facades in Croydon from the safety of the pavement.
Description
The Selfridges building has a long standing history with the city of London, the impressive 5 story building stretches approx 160m along Oxford Street. SES has been appointed to survey the external footprint of the building and key internal structural elements creating accurate and up to date floor/ceiling plans. These drawings will aid Selfridges in the management and planning of floor space which in turn will maximize their productivity.
Detail Surveyed:
- Ceiling Plans - FCL, false ceiling level, intrusive surveys into the ceiling void for soffit and beam detail
- Floor Plans - FFL, intrusive surveys under raised flooring for SSL
- Space - Description of rooms, surface types and finishes
- Walls - Internal partitions, stud wall, solid walls
- Access - Doors, risers, access hatches, fire escape thresholds, windows, stairs, lifts
- Footprint Surveys - Overall footprint area shown
