Topographical & measured building surveys - Manor House, Oxfordshire

Glanville was appointed by university surveyors to provide survey support for the conversion of a private manor house into a research and conference centre.

Glanville's initial works involved establishing control throughout the 30 acre site. Due to the difficulties of access and lines of sight, Global Positioning System (GPS) satellite observation techniques were used.

Detailed external features on the site and secondary control were then observed with robotic reflectorless geodimeter instruments, resulting in significant cost savings with 'one man' surveying.

Major repair and refurbishment of the 1,500 sq m manor house was required, and Glanville provided detailed floor plans of all levels from basement to roof plus full elevation and sectional drawings.

All internal work was controlled using reflectorless laser total stations with infill detail measured with laser distos and tapes.

Due to the complexity of the elevation and section detail and the accuracy required, the latest laser scanning techniques were utilised to provide a three-dimensional point cloud of the external façade.

The survey information was processed through specialist survey software linked to AutoCAD and final issue was as hard copy plans and DWG files on CD.

All drawings were provided to the client's exact specification within the agreed timeframe and under budget.

Survey included:

• GPS control network
• Topographical site survey
• Road survey for visibility assessment
• Drainage survey and tracing
• Floor plans to 1:50 accuracy
• Elevations from laser scanning
• Full detailed sections
