LASER SCANNING
Laser scanning expands surveys to the following fields:
- Architecture, construction & preservation of buildings and monuments
- Laser scanning enables a fast, reliable and inexpensive 3D survey of present structures, buildings and their interior. Laser scanning is typically used, for example, for facades, damages and the building’s documentation as well as to perform dimensionally accurate surveys. Using the obtained results from the laser scanner, the user is able to create volumes, surfaces, layouts, sectional views and more. Laser scanning is the optimal method for the Building Information Modelling (BIM)
- New measurement method providing highly accurate results
- Modern measurement methods, e.g. 3D laser scanning, replace conventional and time-consuming methods while providing far more accurate and detailed results
- Accurate planning with digital models saves time and effort
- Costs, time and effort are drastically reduced through fast and accurate measurements as well as efficient planning and modelling with digital models
BIM / 3D MODELLING
At Topo M Surveys we understand that our laser scanning surveys need to provide an integrated overview of existing site and building arrangements that will facilitate the wider usage of our 3D models by a multi-disciplinary team. Being able to translate these into different software programs and across platforms means that our clients can fully extract maximum value from our surveys. Using this approach the 3D models produced by Topo M Surveys for architectural and engineering design are often also used for marketing, publicity, facilities management as well as a multitude of other applications.
Building information modelling (BIM) is a process supported by various tools, technologies and contracts involving the generation and management of digital representations of physical and functional characteristics of places.
Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset.
BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.
MEASURED BUILDING SURVEYS
A measured building survey refers to the internal and external survey of standing buildings or structures. It can include a variety of outputs ranging from a basic floor plan to a detailed 3D building model.
- Walls
- Ceiling Plans
- Floor Plans
- Space
- Access
- Elevations
- Sections
- built information
- As built surveys
- Complete cross and longitudinal sections showing building as
- Internal partitions, stud wall, solid walls
- Doors, risers, access hatches, fire escapes, windows, stairs, lifts
- FFL, intrusive surveys under raised flooring for SSL and service detail
- FCL, false ceiling level, intrusive surveys into the ceiling void for soffit and service detail
- Full external elevations showing building profile, window heights, roof heights etc.
- Description of rooms, surface types and finishes, floor nett/gross area calculations, service positions as switchers/sockets/comm’s cables
TOPOGRAPHICAL SURVEYS
A detailed topographic survey has many uses across the natural and built environments. Typically they are conducted on a set parcel of land to depict natural/man made features and elevation changes giving you a clear picture prior to any planned works. Detail is accurately measured and the deliverables issued to meet our clients specific requirements. These can range from simple 2D contour plans to detailed 3D AutoCAD / Revit drawings.
- Full feature survey
- A complete survey of the terrain to record the position of the street furniture, road lines, buildings, services, contours, embankments, vegetation etc.
- Boundary verification
- Basic outline of a projects periphery
- Ground levels
- A grid of levels or volumetric calculations
