HP 306 Architectural Conservation I Syllabus
Spring 2008
Lecture: Wednesdays, 12:30 PM to 3:15 PM, Wheeler 101
Lab:
Thursday, 12:30 PM to 3:15 PM, Wheeler 101 or as noted
Instructor: Prof. Thomas
Visser, 207 Wheeler House, Thomas.Visser@uvm.edu
Graduate Teaching Assistant: Jessie Brakenwagen
Course Goals
The goal of this course is to provide an overview of the study of architectural conservation through an examination of historic uses and physical properties of common historic building materials and finishes. To achieve this we will explore the pathology of building materials to help provide an understanding of their deterioration mechanisms and examine strategies for conservation treatments and rehabilitation.
We recognize that the professional preservationist must have a broad understanding of basic analytical and research skills, including a knowledge of historic construction techniques and the abilities:
Another goal of this architectural conservation course is to provide a background for preservationists who will be working with architects, engineers, building trades workers, contractors, conservators, architectural historians, preservation advocates, grant recipients, developers, property owners, review boards and others.
A final goal of the course is to help prepare students for professional positions in preservation that require the review of conservation treatment proposals, architectural designs, and preservation grant applications. This is the first of a two-part sequence of courses with HP 307 Architectural Conservation II following next semester.
Course Readings
Since we have a large amount of information to cover, the text and web-based reading assignments are very important parts of the course. It is your responsibility to keep up with these assignments. These texts will be used for both HP 306 and HP 307.

Lab Project Assignment Descriptions
| Project | Assignment description |
1. Mortar sampling
|
Photograph the mortar on the building before sampling. Note color, texture, and tooling marks. Remove three samples of the same type of mortar from different nearby locations, each between 5 and 10 grams, (about the size of a pat of butter). Place each sample in a separate sealable poly bag or container and label with the following information: your name, sample number, building name, building location, sample location, date of sampling. |
2. Basic mortar analysis
|
Perform a basic mortar analysis on two samples from your building. Save your third sample for reference for lab project 3. Determine the proportions of aggregate, binder and fines by weight. Analyze the aggregate through microscopic analysis and sieving. Summarize the results of your analysis in a short professional report with text, graphs and images that characterize the mortars with sufficient detail to enable a mason to duplicate the samples. The particle size distribution of the aggregate should be presented as a graph. Link to procedure. Download mortar analysis template Excel file. Link to mortar analysis case study example. |
| 3. Producing appropriate mortars | Based on your analysis from lab project 2, reproduce a mortar that matches the appearance your remaining mortar sample from project 1 and has an appropriate hardness for the location conditions of the sample. Submit both your sample and your cured reproduced mortar in labeled clear poly bags or small container. Present a short professional report that discusses your findings from both Project 2 and Project 3. |
4. Concrete, terrazzo
|
Select an area of concrete or terrazzo in a UVM building or other suitable building. Document its composition and condition. Provide treatment recommendations for its maintenance and conservation. Submit your findings in a written report with illustrations. |
| 5. Bricks | Select two bricks for analysis from the collection provided. Analyze the bricks and report your findings with sufficient detail so that similar bricks could be procured that match the color range, surface texture, size, and surface absorbency. |
| 6. Moisture, humidity, and rising damp | Survey an interior exposed masonry surface of at least 30 square feet in Wheeler House or other historic campus building. Record the temperature of the surfaces using an infrared themometer and the temperature and relative humidity of the air using a psychrometer. Record the fluctuations in temperature and relative humidity in the space over a 24 hour period using a digital data logger. Download this information and convert it into an Excel file that can be analyzed and included in your report. Survey the surface area visually and note evidence of rising damp or condensation. Record your findings on a grid map elevation of the area. Survey the relative subsurface moisture levels of the area with an RF moisture meter. Record your findings on a second grid map elevation of the area. Diagnose and report the sources of any rising damp or condensing moisture. Present your findings in a short professional report with separate grid map overlays for the visual evidence and for the subsurface moisture meter findings. |
| 7. Plaster and parging | Select an area of flat or ornamental plaster or parging in or on a UVM building or other suitable building. Assess and document its condition. Provide treatment recommendations for its maintenance and conservation. Submit your findings in a written report with illustrations. |
| 8. Wood | Assess the condition of the sample of deteriorated wood, including a determination of its moisture content and whether there is any evidence of deterioration from fungal or insect activity. After preparing an area for treatment, use appropriate consolidants and fillers to conserve a section of deteriorated wood. Leave some of the sample untreated for comparison. The work should be smoothed and primed so that it is ready for finish painting. Submit your conserved sample with a conservation treatment report that documents the initial conditions and the treatments and materials that were applied. |
| 9. Paint sampling | Select an historic building with some historic finishes in fair condition. Obtain permission from the owner to take several small paint samples in obscure areas. Remove two paint samples from different locations, each between 1/8 inch and 1/4 inch square. Be sure the samples go entirely to the substrate. Place each sample in a sealable poly bag and label with the following information: sample number, building name, building location, sample location, date of sampling, your name. |
| 10. Finishes analysis | Mount small pieces of the paint samples in a petri dish filled with paraffin. Perform a microscopic analysis of the cross sections of each sample to determine the number of layers of finishes. For each layer, describe the color and the closest Munsell color match as observed. Also, provide a match from the original color (extrapolating for the effects of age) to a commercial paint color currently available. (List the brand, line, color number and color name.) Also note the type of coating for each layer. |
| 11. Paint conditions survey and treatments | Select an historic building with some historic finishes in poor condition that have failed down to the substrates. Document the patterns of deterioration and identify the various conditions that may have contributed to the deterioration. Develop recommendations for treatment that address the intrinsic and extrinsic factors that have caused the deterioration. Provide specific recommendations for paint removal (if appropriate), substrate surface preparation, priming systems, and finishing techniques. List the specific products, colors and treatment techniques to be used. |
