We will work with you to tailor a specification and proposal that suits your requirements. Depending on the size and type of your project we can provide the information important to you.
Using modern technology we will provide you with the most cost effective solution, delivering your information quickly. Using only experienced land surveyors you can be confident that our topographical surveys are drawn to the highest standard. With our extensive experience our surveyors will provide additional information that may be vital to your successful project, such as neighbouring building heights.
Survey drawings are supplied in various 2D and 3D CAD formats and paper copies can be provided. Should you require a topographical survey to support a BIM project we can provide you with a 3D surface model solution to be imported into Revit format.
Topographical Land Surveying
Using the latest geomatic technology including; robotic instruments, utilizing reflectorless theodolites, latest GPS survey equipment and one-man total stations we provide our clients and their consultants with accurate and economical survey solutions for all aspects of land surveying.
Our land survey services are provided throughout the UK. Whether you require assistance with topographical, engineering, boundaries or GPS surveys we have the Survey Solutions.
Setting Out Services
Using robotic survey equipment and GPS technology, along with industry standard software and our own bespoke applications, LHL can transfer data directly from the design drawing to site, without further intervention. Our setting out processes thus eliminates many of the steps in which errors typically occur.
Our setting out engineers can work with:
- Building positions
- External and Internal wall positions
- Pile positions, pile caps, contiguous walls
- Building locations
- Roads, highways, haul roads
- Levels, datums and height transfer
- Drainage systems
- Steel positions, bolt holes
- Concrete shutter lines, slab extents
LHL can provide the complete range of measured building survey services including; floor plans, sections, structural details and elevations.
Each element of the property can be surveyed independently or as part of a fully connected co-ordinated survey which will reference the floor plans, elevations, topographical surveys and underground investigation to a national or local grid and OS or local level datum. This data provides an essential base to model a 3D resource for architects and designers whether for refurbishments, alterations or record purposes.
Volumetric Calculations & Cut and Fill Calculations
We record all site levels and features to generate enough information to create an accurate terrain model. We then overlay it with 3D strings and a formation model produced from the design layout, slicing the data into a number of sections from which the cut and fill volumes can be calculated (a detailed report that includes chainage, position and volume is produced for each section). Finally, we use our soil condition survey to calculate the compaction/bulk factor for best possible volume result.
Structural, Subsidence and Crack Monitoring – Measurements can be taken manually or automatically, depending on the frequency, accessibility and level of accuracy required.
