COURSE DESCRIPTIONS
Archaeology in Historic Preservation
Instructor: Peter Peregrine
Archaeologists are not often integrated into historic preservation teams, and archaeology itself is all too often seen as an “extra” in historic preservation efforts, only undertaken if it is required by law or if archaeological deposits are already known to exist. This course provides an introduction to archaeology that demonstrates the kinds of information archaeologists can bring to an historic preservation project, the value of having an archaeologist on an historic preservation team, and the time and money that can be saved by integrating archaeological research into an historic preservation project from the start. The course will involve lectures, discussions of students’ current or recent projects, hands-on work with archaeological objects, and visits to nearby archaeological sites.

Architectural Paint Analysis
Instructor: David Arbogast
The analysis of architectural paints and finishes, as opposed to those used in the field of fine art, is rapidly developing from its infancy where paint was scraped on site to the present where scientific analysis is being undertaken not only to determine historic colors, but also to determine other aspects of finishes such as composition and application methods. David Arbogast, an architectural conservator with over thirty years of experience in the area of historic architectural paint analysis, will provide hands-on instruction in the microscopic analysis of historic architectural paints and other finishes.
This workshop is being offered at McCrone Research Institute in Chicago and tuition only includes lunch. Students must make hotel arrangments separately.
Exterior Painting for Historic Properties
Instructor: Bob Yapp
This is a hands-on opportunity for students to learn how to achieve lasting paint jobs cost effectively. Historic houses and buildings have a unique set of circumstances that must be understood in order to obtain sustainable paint coatings.
Students will work side-by-side with instructor Bob Yapp on an actual painting project at the Campbell Center. In four days you will learn how to: analyze existing paint conditions; work with lead paint safely; prep surfaces; understand moisture issues and how to analyze moisture contents; apply proper coatings and properly maintain paint jobs. Conservator, David Arbogast will join the class for an afternoon to demonstrate how to analyze original paint colors.
Don't buy into the myth that historic structures cannot hold paint, they can and this course will teach you how.

Historic Hardware Restoration
Instructor: Susan Maltby
Preserving historic hardware is an important component of any architectural conservation project. Whether it be an escutcheon plate, hinge, lock, latch, coat hook, gutter bracket, bale handle or boot scraper they all require special care and consideration. In this one day course we will discuss the materials commonly used for the production of historic hardware; material identification; preservation; replication; finishes; and coatings.
Participants are urged to bring examples of historic hardware for discussion.

Understanding Historic Masonry Mortars
Instructor: John Lambert
Lately, confusion and misunderstanding surround the topic of historic masonry mortars and today’s repointing mortars. A clear understanding of the differences between prominent historic mortar binders such as lime putty, natural cement, pozzolans, hydraulic lime, Portland cement and hydrated lime is essential for architects, contractors, historic building owners, masons and preservationists to intelligently specify and correctly use these materials today.
This intensive course is not taught or sponsored by material suppliers. Therefore, the training you receive is unbiased and not influenced by potential product sales. It will help dispel many falsehoods and deepen your knowledge of the subject. The objective of this 2 day course is to increase your understanding of the many binders, aggregates and additives traditionally used in American masonry mortars between the late 1,600’s and 1950 and how these materials are best used in today’s repointing mortars.
Among the things you will learn:
- The history and evolution of early American mortars. Important historic documents are ex examined that tell the story. See things through the eyes of the architects, engineers, contractors and mason’s throughout history.
-When, why and where various mortars were used.
-The uncommonly known, yet critical roles of historic mortar.
-The all important relationship between mortar and the masonry units it surrounds.
-The physical characteristics of various mortar binders and aggregates.
-Factors influencing mortar pathology.
-Advanced strategies for enhancing the performance and durability of matching repointing mortars.
-What there is, and is not to gain from having a mortar analysis performed.
-The secrets to deciding which repointing mortar recipe is appropriate for what application today.
-How to intelligently develop a scope of work for which mortar joints should be repointed.
-The new ASTM C1713 -10 Standard Specification for Mortars for the Repair of Historic Masonry.
Hands-on learning allows you to mix, feel, observe and work with:
- Lime putty
- Natural cement
- Hydraulic lime
- Portland cement
- Hydrated lime
- Various aggregates
This intensive workshop equips you with the knowledge to insure the highest level of mortar material selection and workmanship. To insure the highest quality of instruction, class size is limited. This workshop is being held in Salt Lake City, Utah.
Introduction to Historic Preservation Theory
Instructor: David Arbogast
Rare is the architect or firm that does not encounter a project in historic preservation and rare is the architect or firm that has the experience and expertise to understand the intricacies of these projects and their clientele. David Arbogast, an architectural conservator with over thirty years of experience in the field, will walk you through the common aspects of these projects ranging from the governmental agencies and regulations which frequently determine the outcome of the project to typical clientele to working with various preservation consultants.
Historic Window Restoration
Instructor: Bob Yapp
In our constant struggle to preserve original materials in historic homes, buildings and museum properties, original wood windows present one of our biggest challenges. The pressure to replace is backed up by multi-million dollar advertising campaigns perpetrated by the replacement industry. In the preservation movement's effort to lead the "Green Movement", we must constantly show the world that nothing is greener than an original window or existing property.
This course is an intense four day, hands-on workshop that deals with these very issues. Students will learn by doing as they work side-by-side with instructor Bob Yapp. Every aspect of efficient and cost effective wood window restoration will be addressed. Students will work in teams. Each team will completely restore two double hung wood window openings including: sash removal; safe lead paint & putty removal; historic glass retention; painting; glazing putty installation; weather-stripping; re-installation of the sashes including how to re-string sash weights.
Specification Writing for Historic Preservation
Instructor: Wayne Smith
The preparation of written specifications for historic preservation projects presents a genuine challenge for most specification writers. For most architectural firms, these are not typical projects and the possibility of errors and omissions is extremely high. Unfortunately, there are no standard sets of specifications which can serve as models primarily because of the unique nature of preservation projects. This course will examine in detail methods of writing specifications which can effectively describe the work most commonly encountered in preservation projects. David Arbogast is an architectural conservator with over thirty years of experience in collaborating with architectural firms and Wayne Smith is a registered architect with an equal amount of experience, much of it spent in writing architectural specifications.
back to topLog and Timber Frame Building Preservation
Instructor: Joe Gallagher
This class is designed for the cabin owner, manager or any body responsible for a log or frame building. It will cover the basics of log and frame building condition assessment and problem diagnosis; restoration strategies; repair options and long term maintenance planning.
The class will visit local structures to learn the discipline of building assessment and write their own assessment plans for a local log or frame structure. Participants will learn to hew and notch logs and develop an understanding of the means to make repairs of even seriously damaged structures. Lastly the participants will write their own maintenance plan for the local evaluated building or for their own building.
The class will be a mixture of lecture, direct observation and hands on activities. Upon completion of this class students should feel comfortable examining their own buildings and identifying problems, repair options, and restoration possibilities. They will also be able to develop a long term plan for the maintenance of their buildings.
Students are encouraged to bring to the class, photos of their buildings for discussion during and after the class.
back to topHistoric Masonry Restoration
Instructor: John Lambert
This 3 day course addresses the most common challenges typically encountered by historic masonry professionals today. The objective is to increase your understanding of the various strategies, techniques and materials for correctly restoring historic brickwork, stone and terra cotta. The workshop is tailored to address the individual needs of workshop participants. Participants are encouraged to bring samples of materials, photographs, etc. that illustrate their specific masonry challenges for workshop discussion and techniques demonstration.
Among the things you will learn:
- How historic masonry structures were built and designed to function
- The important differences between modern day and historic masonry
- Approaches to inspecting / evaluating masonry structures

- The uncommonly know, yet critical roles of historic mortar
- Where, when and why water repellents may, or may not be appropriate
This intensive workshop equips architects, specifiers, masons, contractors and building owners / property managers with the knowledge to insure the highest level of historic masonry restoration practice and materials. This course is a nice compliment to (but not a prerequisite of) the Repointing Historic Masonry workshop which is held the 2 days immediately following this course. Discount available for attending both courses. To ensure an ideal learning environment, class size is limited.
Overview of American Architectural Styles
Women’s fashions, cars, furniture, and architecture, to name only a few examples, exhibit an evolution of styles over time. Th is course examines the progression of styles in American architecture. Style characteristics will be illustrated and discussed in a slide-lecture format. The technique of stylistic comparison used in the study of the visual arts will be employed in class. Questions and discussion will be encouraged. Field work in Mt. Carroll will allow students to become familiar with the characteristics of individual styles and to practice applying their style knowledge to individual buildings. Knowledge of architecture styles is not an end in itself. Its primary use in the fi eld of Historic Preservation is to determine a building’s date and to give it a style classifi cation. Style is a tool that gives us a glimpse into our cultural history. The course examines questions such as: “what is period style?,” why are there revivals of previous styles?,” “are there moral attitudes associated with styles?” and other questions. Along the way it is hoped that students will sharpen their powers of observation and analysis.
Passive Wood Floor Restoration and Repair
Instructor: Bob Yapp
This is an intense, four day, hands-on, learn-by-doing opportunity. This class is not about aggressively drum sanding wood floors so they look new. Much like fine antiques we want to keep the character defining features and patina of the flooring.
You will be working side-by-side with instructor Bob Yapp restoring an oak, tongue and grooved floor in a building at The Campbell Center. Students will learn how to patch bad areas so they don’t look patched, passively remove the damaged old finish, remove water and pet stains as well as how to apply a finish.
At the end of the four days students will know from beginning to end, how to repair & passively restore any hardwood or softwood tongue & grooved strip floor. Students of all skill levels are encouraged to enroll. Bring work clothes, knee pads and safety glasses.

Preservation of Gravestones and Cemetery Monuments I: Basic
Instructor: Jon Appell
The primary goal of this workshop is to educate the attendees regarding all of the various aspects of gravestone, monument, and historic masonry preservation.
The majority of the workshop will be conducted at a local historical cemetery.Classroom instruction will complement the hands-on training. The workshop will begin with a walk and talk tour, using the cemetery as an open -air museum to illustrate; basic geology, common preservation problems, previously failed repairs, and assorted other related issues. Gravestones and monuments, will then be selected to be repaired, cleaned or preserved in some manner, which represent most of the commonly encountered preservation problems, found in historic graveyards.
The following list of preservation treatments will be performed during the during of the workshop, as well as other assorted procedures:
We will perform the re-setting of a tablet-stone, which may be in a badly leaning, and or sunken condition.
The repair of a broken gravestone will be conducted, by joining together the fractured stone fragments employing stone epoxy.
The re-construction of fallen and or badly leaning multiple piece cemetery monument will be demonstrated, with a discussion on the historical use, and option to employ blind pinning.
The use of historic pointing mortars and composite patching material will be overviewed and demonstrated, with an emphasis on the need for mortars which are compatible with the historic substrate they are being applied to.
The process and potential need for consolidation of weak and decayed stone will be overviewed.
The issues and problems associated with sealing stone will be discussed in detail.
An in depth demonstration on stone cleaning will be conducted, and performed by the participants.
Cleaning is not something that should be indiscriminately performed, as some stone is too weak or fragile and may be harmed; many cleaning agents and chemicals can be detrimental to historic stone. Therefore the philosophy of cleaning will be discussed, and safe cleaning techniques will be demonstrated on gravestones which will benefit from the cleaning treatments.
A folder containing printed information will be provided to further educate and inform students, regarding the conservation treatments and materials employed throughout the workshop. Questions, interaction and group discussion is encouraged
.Participants are welcome to bring along photographs of historic masonry, sculptures,
or gravestones which they have concerns or questions regarding.
Preservation of Gravestones and Cemetery Monuments II: Advanced Techniques
Instructor: Jon Appell
This advanced workshop will be a continuation of the basic gravestone preservation workshop.It will cover more complex gravestone and monument conservation treatments and procedures.
The following techniques will be performed during the workshop as a group interactive experience:
A basic overhead stone lifting tripod will be constructed and employed to raise large fallen and or badly leaning monumental elements which are too heavy to lift by hand.
The rigging of stone in order to be lifted will be demonstrated.
The joining and setting of monuments will be performed.
Composite stone in-fill materials will be discussed in depth, and applied to various kinds of substrate.
Pigments will be added to modify and create a color matching in-fill mortar.
Injection grout will be used to in-fill small cracks and voids, and help prevent freeze- thaw damage.
A replacement base will be cast out of concrete, in order to repair a gravestone fractured at or below the ground surface. After the concrete has cured, the tablet stone will be re-set into a socket base employing a historic pointing mortar.
Cleaning techniques will be covered in greater detail including the application of stone poultice to remove in ground staining.
The consolidation of a marble gravestone will be performed to strengthen the stone, and help prevent future degradation.
Additional preservation treatments will be discussed and performed based on the time allowance.

Writing Historic Structures Reports
Instructor: David Arbogast
Without a doubt the most essential and, unfortunately, the most neglected investigation document used in the preservation of historic structures is the Historic Structure Report. A well-written HSR provides the necessary data for not only significant intervention in a historic structure, but for the on-going curatorial care of the structure. Historic structures can be viewed as very large, highly complex artifacts requiring highly skilled care. This course is designed for those given the responsibility both for the commissioning and for the preparation of Historic Structures Reports. It examines all aspects and sections of the Historic Structures Reports, using available HSRs as examples to examine and dissect so that a new level of excellent will be achieved in the writing of these vital documents.
The instructor, David Arbogast, is an architectural conservator with over thirty years of experience in the field. His book, How to Write a Historic Structures Report, has recently been published and will be used as the text for the course.
___________________________________________________________________________
Instructor: David Arbogast
Although the field of historic preservation seems to be dominated by spasmodic restorations of buildings, the hard work consists of the regular, routine maintenance of these resources. This course has been developed to address those needs both in the short-term and in the long-term cycles. It is intended both for those actively engaged in maintenance and for those responsible for the management of the resources.
The instructor, David Arbogast, is an architectural conservator with over thirty years of experience in the field. He brings to the course a wealth of experience and knowledge both from the professional and from the occupational maintenance of historic resources.

Methods and Materials for Maintenance of Historic Buildings
Instructors: Bob Yapp and John Leeke
This course has been developed in cooperation with The National Park Service Training Center in Fredrick, Maryland.
This course is designed for people who maintain historic properties. John Leeke and Bob Yapp, two of America's top hands-on, historic preservation and maintenance professionals will be teaching the course.
This is not a theory or planning course. John and Bob will be demonstrating actual materials and methods used to maintain historic properties of all varieties. You will learn how to identify the underlying conditions that create maintenance problems as well as the proper use of products and methods that have been tested in the field.

Historic Architectural Interior Finishes
Instructor: Mary Jablonski
This workshop is based on a course Ms. Jablonski teaches as Columbia University, NYC.
Architectural finishes record an ephemeral history of our built environment. Finishes tell us a story about how we have over time decorated, ornamented, and protected wooden elements on our buildings. As we record and preserve our buildings, it is important not to only consider the outer shell of the building but how people saw and expressed themselves in the finishes of their homes and public buildings.
This class will look at a variety of finishes but focus on paint and wallpaper. The course will be a mix of lectures and microscopic work. As we examine paint finishes, we will discuss the issues of how to sample, the differences between a paint color investigation and a paint analysis and the importance of “exposure windows.” The class will work on microscopes to perform paint color investigations and some paint analysis. The other finish we will be looking at in detail is wallpaper which is also ephemeral and often found in fragments or badly damaged. How to investigate and date wallpaper along with conservation issues regarding this paper thin finish will be discussed.

Energy Efficiency for Historic Houses & Buildings
Intructor: Bob Yapp
Just because it's shiny and new does not mean it will work for your historic house or building. This hands-on and lecture workshop dispels the myths and addresses how historic structures were designed. Bob talks about what retro-fits for energy efficiency actually work as well as paybacks. Insulation, air flow, weather stripping, windows, geo thermal, solar and wind are all topics of discussion. Students will actually perform weatherization techniques to a historic building on campus as well as seeing how a blower door test actually works to identify air infiltration. This workshop is designed for home owners as well as individuals responsible for the care and amintenance of historic house museums.
