Biltmore Estate Conservatory
Asheville, North Carolina
Sutton-Kennerly & Associates, Inc. conducted a condition survey and investigation of the Biltmore Conservatory, built in 1893 at the Biltmore Estate in Asheville, North Carolina,  that revealed severe water leakage throughout the structure and a severely corroded steel beam support structure at a number of locations within the brick arch/concrete/structural steel floor.  SKA prepared construction documents for restoration of structural steel and masonry combined with the installation of a waterproofing membrane and brick paver system over the concrete covering the brick arches.

Alumni House
The University of North Carolina at Greensboro
SKAs' mechanical/electrical/plumbing engineering services have been enlisted by a local architect to aide in the restoration of this historic house on the campus of UNCG.  This project is currently active and is scheduled for completion in 2007.  Previously, SKA's Roofing/Waterproofing group prepaired contract documents for renovations to the alumni house's elevated walkway due to extensive leakage that had deteriorated the concrete as water seeped through cracks and corroded the reinforcing steel.  Repairs included removing handrails, flagstone paving and existing waterproofing, and installing a new waterproofing membrane, drainage mat, setting bed and flagstone paving.  Handrails were modified and reinstalled.  SKA also provided construction observation and contract administration services on this project.

New East Building
The University of North Carolina
Chapel Hill, North Carolina
SKA provided structural and mechanical\electrical\plumbing design services for renovations to this historic residence hall.  Renovations included demolition of an air cooled chiller, existing multiple fan-coil units and associated controls, ductwork and electrical; asbestos abatement; installation of new central air handling units; new DDC controls to connect to campus central control systems; new electrical service; and connection to a recently installed campus chilled water loop.  Structural work included excavation of basement crawl space, installation of concrete slabs and retaining walls in new basement, three vertical mechanical shafts through floors, and catwalks and mechanical unit supports in attic.

Duke University
Durham, North Carolina
Sutton-Kennerly has also completed several historic dormitory renovations for Duke University: Kilgo Quad, FEW Quad and Wannamaker Residence Halls .  Please see our Universities page (currently under construction) for more information.

Houston Mill House
Emory University, Atlanta, Georgia
SKA provided design and contract administration services to Emory University for the replacement of the roof of the historic Houston Mill House.  This project involved steep slope slate replacement, composite underlayments, and replacements of gutters, downspouts and flashings.

Person County Courthouse
Roxboro, North Carolina
Severe leakage prompted an investigation and condition survey of the building envelope of this historic courthouse built in approximately 1930, with an addition built in 1978.  SKA recommended 100% tuckpointing of the brick masonry, removal and replacement of one floor height of masonry around the perimeter of the addition, partial window replacement, reflashing of window lintels, repointing of cast stone joints and coating of all cast stone on both buildings, removal and replacement of structural framing, deck and roofing on the upper level roof and replacement of roofing membrane on the low roofs.  SKA prepared contract documents and monitored construction for a two-phase repair project completed at the end of 2003. 

Stokes County Courthouse
Danbury, North Carolina
SKA conducted a condition survey of masonry deterioration, corrosion of metal fascia/cornice, and water leakage of this historic courthouse.  Cost estimates and materials for repair were developed, and contract documents were prepared for remedial repairs consistent with the requirements imposed by the National Historic Register.

Alamance County Courthouse
Graham, North Carolina
This historic courthouse was experiencing serious deterioration of the upper level terra cotta facade and interior finishes.  SKA teamed with a restoration contractor to disassemble and examine a portion of the terra cotta balustrade and architrave.  Sources of water intrusion and deterioration of  embedded steel anchorage as well as structural supports were documented.  SKA prepared restoration documents and monitored construction that included a new roof, new structural steel framing within the facade, and replication and replacement of the entire perimeter balustrade and water table, as well as the architrave and soffit on the north and south faces, with glass fiber reinforced concrete members.

First Presbyterian Church
Charlotte, North Carolina
SKA was responsible for the design of remedial repairs for this historical gothic structure that included a new exterior cladding system to be anchored into a one-hundred year-old masonry wall. The cladding system was a fiber reinforced plaster (FRP) wall that was designed to allow the existing masonry wall to breathe, using a one-inch cavity created by the anchored metal hat channel studs.  The design also included a new roof drainage system to properly control water runoff.

Main Street United Methodist Church Bell Tower Investigation and Rehabilitation
Danville, Virginia
SKA conducted an investigation and engineering study on the severely deteriorated 100-year old masonry bell tower for this historic church.  Contract documents for rehabilitation of the bell tower were prepared to meet requirements imposed by the National Historic Register.

Forsyth County Government Center
Winston-Salem, North Carolina
SKA provided structural engineering services to a local architect on the complete renovation of three interconnected buildings built by the R.J. Reynolds Tobacco Company, labeled "12-1", "12-2" and "12-4".  Building 12-1 was originally constructed in 1915, Building 12-2 was built in 1917 and Building 12-4 in 1967.  After conducting a condition assessment and evaluation of the existing structural systems in these buildings, SKA  prepared designs and construction documents for structural repairs to the cast-in-place concrete members in Buildings 12-1 and 12-2, modifications to Building 12-1 for use as a parking deck, modifications to Building 12-2 for a new atrium, escalator, stairs and miscellaneous stores, modification of the upper floors and roof of Building 12-4 to accommodate larger rooms, a new stair tower, and new retaining walls.  Sutton-Kennerly also provided extensive construction inspection services on this complex project.

First Union Building
Winston-Salem, North Carolina
Masonry cracking and severe corrosion of structural steel corner columns on this 18-story, 1926 office building required restoration and repair based on the results of a structural evaluation and condition survey. SKA prepared contract documents for remedial repairs including exposing steel columns, removing existing corrosion, strengthening columns, installing waterproofing and flashing systems, and reconstructing masonry veneer at corners.  Sutton-Kennerly also monitored the construction of this project.

The Helmsley Spear
New York, New York
The top floors of this historic 40-story building overlooking Times Square exhibited severe deterioration of the concrete encased steel structure.  SKA's comprehensive investigation included an evaluation of corrosion, concrete deterioration and leakage.  SKA recommended repairs of structural and waterproofing systems and restoration of decorative elements including the copper covered dome, lighted torches and spire.
