Topographical Land Surveys
A comprehensive land survey is one of the key tasks of any building development. An accurate and thorough survey provides the foundation for all future work to proceed with confidence.
I aim to provide a professional service to clients that call for the services of a Land Surveyor. Architects, Engineers and Developers need precise information to plan site development from inception to completion. A comprehensive land survey will not only provide the boundary and detail within in a site but also potential restrictions and problems that may be encountered. The benefits of commissioning a site survey cannot be understated.
The latest survey technology is used. We use Trimble S6 Robotic Total Stations. The speed of data acquisition is a marked improvement on the 2- man operation. The instrument not only surveys faster but it cuts out the need for an assistant. A saving that is passed onto the customer. A crucial component of the Trimble S6 is direct reflex measurement. Clients are increasingly asking for ridge and eave levels of buildings. With direct reflex technology it is possible to quickly and accurately measure objects that are impossible to access.
To process data we use a combination of LSS and AutoCAD software. The finished product can be a paper plot or a DWG/DXF drawing file emailed or shared through our server facility.
3D Laser Scanning
3D Laser Scanning is a fairly new technology, having been used as a precise survey instrument only since around 1998. Now it is quickly becoming the new industry standard as a way to make very accurate measurements in complex environments.
CESurveys Ltd utilise the very latest in Leica 3D Scanning technology, to allow our surveyors to offer you the best service on the market. A 3D scan is highly accurate, with fast turnaround and significant cost saving.
3D laser scanning is excellent at reducing or eliminating problems with hard to reach areas, issues around safety and time restricted access. The complex data allows analysis and segmentation of any part of the point cloud within the CAD environment, thus offering our clients access to a greater level and quality of information.
The value of earthworks forms a significant part of any construction project so it is crucial to have accurate cost analysis undertaken both before and during the construction process. By comparing design information to existing and proposed land formations, earthwork calculations can be worked out to facilitate a highly accurate cost analysis.
Volumetric surveys are carried out in a very similar manner to Topographical Surveys, but with additional attention focussed on the geometric shape of the land area. Using the latest modelling software, combined with information gathered on site, we can then produce an accurate 3D model of surveyed surfaces so as to produce accurate volumes of specific stockpiles, quarry faces or landfills.
This analysis can then be delivered to the client as a stand-alone document or alternatively the information can be embedded into a drawing as text with long / cross sections and isopachite contours to visually describe the cut and fill areas.
The role of setting-out is to stake out reference points and markers that will guide the construction of new structures such as roads or buildings. These markers are usually staked out in accordance with a suitable coordinate system selected for the project.
The value of undertaking accurate setting-out for any type of construction project, large or small, cannot be over-estimated. It will serve to ensure that all works are undertaken within the specified legal boundaries, which is vital to make certain that there are no boundary disputes at a later stage. It will also assist in ensuring that the construction firm build exactly to plan.
We are vastly experienced in the setting out of a wide range of construction projects and can extract setting out points directly from AutoCAD files.
Accuracy is paramount and if a sufficiently high-quality survey has already been undertaken in the past then we can utilise that information to work from when on site. Our highly skilled surveyors will check that the architect’s data is adequate and clarify the required accuracies for the project.
Internal Building Surveys & Elevations
Cornish Engineering Surveys are highly experienced in providing a comprehensive range of internal and external measured building survey services.
A measured building survey provides a highly accurate representation of your building showing all the significant structural elements and architectural features.
Floor plans are vital to give an accurate representation of the building and this is backed up with elevations and cross sections presented as a scaled CAD drawings.
External elevation drawings can be provided independently or as part of a complete building survey. We can deliver 3D models and visualisations of building exteriors.
The detail included in within the survey will depend entirely on your requirements, and may vary for the purposes of design, planning or feasibility.
Deformation monitoring (also referred to as deformation survey) is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads. These type of surveys are becoming ever more crucial as the stability of ageing infrastructures and structures are at stake.
Cornish Engineering Surveys can provide you with comprehensive advice on the most suitable deformation monitoring technique for your project.
Using the very latest in technology, we are able to offer highly precise real-time surveys, tracking movments to 0.1 millimeter accuracy. Surveys can either be manned on site or monitored remotely depending on your requirements.
Boundary surveys are most commonly used to determine the legal ownership of a specified plot of land. They usually require far less detail than a full topographical survey and hance are plotted at a smaller scale (1:1250 or 1:2500).
Cornish Engineering Surveys provide a highly accurate and prompt boundary survey service which will prove essential in resolving a boundary dispute or to assist in re-establishing old boundary lines and may avoid the need for expensive court costs.
Our boundary surveys can be overlaid on Land Registry or historic maps in order to determine any variations. Surveys are linked to Ordnance Survey National Grid which means that Title Plans for land registration can be easily produced.
