Case Study: Scan-to-BIM

Project: St Winfrid's Church, Totton (BIM)

St Winfrid’s Church, within the Diocese of Winchester, is a red brick Grade 2 listed building constructed in 1937 by the 20th Century architect Nugent Cachemaille-Day. It is described on the Historic England website as a Parish church with walls of brickwork in English bond, arched openings, parapets and a pantile roof. Resembling an early Italian basilica, it has exaggerated horizontal dimensions; a nave with aisles and a tower at one corner surrounded at its base with flat-roofed vestries and a large porch having 3 arched openings; the face of the tower features patterned brickwork, in relief, in the form of a cross.

Inside, the external impression of length is changed. There is a square ‘nave’ with orientation across the ‘aisles’ which are separated by single arches rising as curves from the floor level, the ‘aisles’ having half-barrel vaults of plaster. At right angles, beneath the gables, there are upper galleries fronted by two large arches which separate the church from a corridor on each side; a flat panelled ceiling extends across the nave and galleries. The interior is in plain plaster with simple furnishings.

St Winfrid’s church has fallen into a degree of disrepair and the Diocese has commissioned a programme of works to restore the building to a state fit for worship once more. To this end, they required a survey of the property and the development of a 3D model.

Our brief was to:
  • Receive and process the point cloud survey data for the site from our survey partner.
  • Create a 3D building model of the topography of the site together with the exterior and interior spaces to Level 2 i.e. the structure of the building but with specific architectural detail enhancements for:
  • The cross in relief on the main tower
  • Basic window fenestration and RWPs.
  • Two large glazed arches including door and window detail
  • The open ceiling beam and joist structure
  • The altar rail
  • Deliver a Revit *.rvt file and an IFC file back to the architect responsible for the project for input into their Vectorworks and SketchUp software programs.
