Setting out involves interpreting design information and translating into recognisable gridlines and datums on construction projects. High accuracy and precision is paramount in setting out and we are greatly experienced in supplying a comprehensive service from start to completion of construction projects. More recently construction verification surveys have been demanded by clients where point clouds are compared to design and fabrication models.

Using the latest robotic total stations combined with a highly experienced team of surveyors we are able to provide a complete setting out service.

Monitoring
 

Monitoring the movement of structures caused by stability issues or construction activities has become an essential part of construction. It can potentially warn and avoid structural failure by allowing the client to react to any specified movement. Monitoring can therefore save both time and cost. Depending upon the client's requirements we can offer both manual (traditional) monitoring or automated monitoring.

The monitoring of structures has long been established as a service Gwalia Surveyors can offer.

 

Concrete & Structural Scanning
 

Concrete scanning is a non-destructive method of detecting, locating, and mapping concealed objects within solid surfaces. This solution can identify steel reinforcement, cables, conduits, and post tensioning without the need for invasive investigations such as breaking the concrete with trial holes etc. Concrete scanning is particularly beneficial when drilling or coring into concrete, walls, or structures giving the client prior knowledge of elements to avoid.

We can deploy the latest handheld scanners, GPR and detectors, to conduct this service. We can offer real time on site mark-up or post processed results and reporting.

 

Bathymetric Surveys
 

Bathymetric surveys involves the mapping of the underlying bed of hydrographic features such as canals, rivers, and lakes etc. Data capture can be performed by a number of methods which range from manned survey vessels to the latest remote controlled hydrone. All survey vessels operate integrated GPS and sonar systems ensuring high quality data is acquired and delivered.

Once field data has been obtained it can be used to generate depth charts and plans, cross sections, long sections, and bottom profiles of underwater features. Output can be issued in a variety of formats, software, which conform to client technical specifications or the EA's.

 

Drone Surveys - Visualisation & Verification
 

Drones or Unmanned Aerial Vehicles (UAVs) are fast becoming a reliable, cost-effective method of data capture for use in many applications. The rapid development of this technology now makes previously hard to reach environments accessible. Armed with high precision cameras and sensors, drones can record and store data remotely from a position of safety. Together with advances in software development, drones can now be applied to a number of survey based, visulalisation, and verification activities of the built environment.

High quality imagery captured by drones can be processed using photogrammetry software to produce high quality point clouds. This data can then be used to manufacture an array of deliverables such as 2D drawings and 3D models, similar to the laser scanning process.
