Brick and Stone Masonry Restoration
For 20 years, DRC Associates has maintained a strong presence in
forensic evaluations, repair, restoration and strengthening of
modern and historically significant buildings, We have completed
more than 100 projects ranging from general purpose structures, to
early American industrial and religious structures. Damaged
structural masonry many times implies damage to other structural
elements of the building. We have not only engineered the rebuilding
or strengthening of masonry buttress walls, towers and arches, but
also heavy timber trusses and arches, structural tile floors, brick
arch floors, wrought iron and cast iron structures.
Harrow East Building - Parapet Reconstruction
investigation questioned the stability of the 10-foot high parapet
walls. A report with options was submitted to the owner. Detailed
engineering documents were prepared for re-construction.
new parapet wall was constructed to a lower height incorporating
many of the original architectural stone pieces.
in 1891, the 173-foot tower houses the Cornell Chimes. Phase one
consisted of forensic engineering, report and recommendations.
|Phase two consisted of the complete reconstruction of
the stone and brick tower, which included:
|Replacement of Belfry stones, arches and columns
|Replacement of anchors bolts and repairs to the spiral steel
|Restoration of mortar joints
|Installation of a new 3 level steel frame to support the Cornell
study concluded that the lack of soft joints to relieve temperature
movement in the brick veneer, resulted in brick damages located
primarily at the steel lintel supports.
included the replacement of the damaged brick, and corroded steel lintels,
installing of new spandrel flashing, and the creation of soft joints.
Work was completed on all building elevations
