Mount Olive Church, Maryland

Steeple & roof of a 100 year-old landmarkwere destroyed by fire

Task: Capture measurements of churchstructure & bell tower to aid in restoration

Challenge: Structural instability preventsaccess to upper portions of building.

Solution: Scan structure and create CAD

drawings and 3D models for restorationpurposes.

Aftermath of the fire

A FARO LS880 mid-range laser scanner was set up in the center of the churchproper and in the tower, and, within minutes, the desired data was acquired.

Above are static screen captures of the interior of the church proper. These data can

be used for deformation analysis of the walls and floor, as well as measurements for

the restoration and repair.

Scanner was set up in the church tower. Scan image of the stained glass window.

Scan images illustrating interior wall profiles, floor, and staircase of church tower .

Scan images illustrating exterior of church tower and partial model and drawings made from scan data.

Architectural CAD drawings made

from three-dimensional scan data.

Following the fire, the structural integrity of the building’s walls and tower were substantially

weakened. In most areas of the building, traditional methods of measurement and architectural

documentation were not possible due to inaccessibility and dangerous unstable conditions.

Measured drawings in CAD format provided information unattainable using standard methods

Finials are sculptured ornaments,often in the shape of a leaf or flower,

at the top of a gable, pinnacle, or

similar structure.

A damaged finial that was deformed byheat of the the fire was rescued. A

Konica-Minolta VIVID 9i digitizer (laser

scanner) was used to scan the object in

the AIST lab.

The highly accurate close-range scan data can be used to reform the damaged

object back to its original shape. From there the finials can be replicated and

placed in their proper position on the reconstructed church spires.

We are grateful for the assistance provided in this project by Direct Dimensions, Ownings Mills, MD, and Eduardo Oliveras.
