Amanda Stauffer Park
I. Introduction
A. Grace Church

A. Step 1: Archival Research
1. Alteration Chronology (Summary)

overpainting and replacement of the altar and floor
(4) 1909: replacement of wood columns with stone
columns and arches, and the repainting of ceiling

Grace Church
2. Principles carried forward into 2012 Design Development by
EAA
a. Maquettes and renderings
3. Challenges
a. Client preference for piecemeal aggregate of original
elements rather than a unified, historically accurate
approach
b. Public distaste for original palette
c. Budgetary restrictions
d. Rejection of original rendering
B. Development of Multi-pronged approach
1. Conservation
a. Full exposure of the ceiling, trusses, and beams
2. Replication
a. Spandrel medallions, dado, frieze
3. Reference in new design
a. Cornice
b. Wall field
V. Mock-up Phase and CD Phase
A. Benefits of having a large-scale mock-up
1. Mock-up Findings during Mock-up Investigation
2. Mock-up Treatments

Part One The 1857 British Museum represents a novel turning point. A brief description and three samples of pre‐industrial decorative plaster Reference to the Industrial Revolution and its effect on building technology generally Evolution of Fibrous Plaster as a commodity in building construction Two Tracks of Development Utility Fibrous plaster is the pre‐cursor to sheet rock Less expensive, more efficient, and easier to control method of achieving plaster finished surfaces on buildings Example shown is St. Augustine’s Church, South Slope in Brooklyn Elaboration Fibrous Plaster facilitates the grand exuberance of The Belle Epoch (1870 – 1915) Three typical examples are shown. Fibrous Plaster requires the simplification of designs Repetition of thin cast elements Creates apparent complexity with repetition Examples are shown from trade catalogues A nine‐point summary of the claimed attributes of all Fibrous Plaster ceilings and embellishments is given Part Two How Fibrous Plaster is made Description of the four‐step process for making fibrous plaster panels Description of the installation process Introduction of the non‐technical term “wad” to describe the fastening of Fibrous Plaster ceilings What goes wrong with Fibrous Plaster after installation? Description of the three main causes of failure or concern Water Infiltration Mechanical Damage Anticipation of future Seismic Events Description of the Parliamentary Precinct in Ottawa, Canada and the prevalence of large buildings with Fibrous Plaster ceilings
Discussion of the use and lack of use of metal armatures in Fibrous Plaster assemblies Caution regarding the need to establish the presence of such an armature during any inspection and the recommended use of metal detectors in inspection. Brief description of two typical Fibrous Plaster ceilings in buildings in the Parliamentary Precinct in Ottawa Part Three Treatment Options Brief illustrated description of a hand lay‐up method of reinforcing Fibrous Plaster ceiling panels Brief illustrated description of a high volume spray application method of reinforcing Fibrous Plaster in the Parliamentary Precinct in Ottawa. Conclusion The fundamental Inspection requirement for a Fibrous Plaster Ceilings Assembly is to establish the presence or absence of a metal armature within the matrix of plaster.
COLORING IN THE GUIDELINES: Development of an Exterior Paint Color Palette for Savannah’s National Historic Landmark District
Presenter: Kathryn A. Stephens Session: CS21 Changing Taste: Preserving Decorative Finishes Date: Tuesday, October 15, 12:15-1:45 PM I. Introduction to topic:
a. Overview of paint color review process in Savannah b. Needs of the Metropolitan Planning Commission to be able to analyze color use more
appropriately; goal was to create a palette/brochure for use by staff and district residents c. Overarching themes: color in the built environment, legality of color regulation,
methodologies for architectural paint research II. Project Methodology
a. Began with analysis of historic color use on a national scale; can be divided into six major periods (Early Colonial, Late Colonial, Federal, Romantic, Victorian, Colonial Revival)
b. Comparing these national trends with evidence from Savannah highlighted some specific regional characteristics, but showed that there was little variation in color use. Existing variations resulted from:
i. Patterns of national and international trade ii. Popular modes of transportation
iii. Savannah’s unique architectural character III. Evidence for Regional Color Use
a. Sources included historic accounts, period advertisements, historic imagery, and analysis reports from individual structures
b. Brief overview of each period of regional color use and sources: i. Colonial (1733-1790): reds, browns, blues, grays in monochromatic schemes
ii. Federal (1790-1840): whites, creams, grays with darker trim in greens and blues iii. Romantic (1840-1870): soft earth tones (grays, browns, pinks, yellows) with trims in
subtle shades iv. Victorian (1870-1900): rich tertiary shades in polychromatic schemes v. Colonial Revival (1900-1920): whites, creams, pastel blues and yellows with
contrasting trim IV. Results
a. Research was distilled into a palette of 95 colors divided into three periods i. Colonial and Colonial Revival periods not included as separate distinctions in the
final palette because no early structures survive and little regional evidence for the Colonial Revival period could be found.
ii. 25 colors in the Federal palette, 25 colors in the Romantic palette, and 45 colors in the Victorian palette; intended to be used in a cumulative manner, meaning colors from a structure’s period of construction and any earlier colors can be used on its surfaces
iii. Specific color references were taken from the findings of experienced paint analysts and presented as Pantone swatches (Pantone used for accessibility reasons)
V. Limitations/ Future Research a. This project intended as a first step in understanding Savannah’s exterior decorative finishes b. Needs to be supplemented with additional physical investigations and documentary research c. Allows the city’s preservation staff to justify their decisions on color use, allows residents to
choose from a variety of colors, and provides a framework for future research
