CPI Technical Training Workshops – 2019

Colorado Preservation, Inc. is partnering with Humphries Poli Architects to present three technical workshops in 2019.

The two half-day workshops (Assessments and Masonry) have a standard, flat tuition rate of $60 ($50 for CPI members). The full-day workshop (Timber) has a flat tuition rate of $125 ($100 for CPI members).

CPI staff will cross-check your membership status to ensure dues are current and may follow-up if they are not. You can become a member on the CPI website here:  http://coloradopreservation.org/get-involved/membership/

Trainees are responsible for securing and paying for travel, lodging, and meals while attending.

This workshop will be held on location at the Argo Mill in Idaho Springs.  The Argo Mill was a state-of-the-art mill when it was constructed in the early 1910s.  The mill was listed on the National Register of Historic Places in 1977.  The Argo Mine and Mill have generously made the mill available for this workshop on Timber and Timber grading.  The mill will be the host to an exploration of the grading protocol for structural lumber and timer in historic structures as developed by Ron Anthony of Anthony & Associates for the National Center for Preservation Technology and Training. This document will be the basis for our hands-on grading of the structure of the mill.  The workshop will include a tour of the mill and an explanation of the history of the property.  A discussion regarding the need for a way to grade historical wood structures and typical timber materials found in Colorado structures will be held before the group turns to the job at hand.  Tools needed for non-destructive testing will be provided to the teams as small groups tackle various portions of the building.  In addition to determining the grade of the historic timbers, an assessment of the condition of the timber being graded will also be conducted by the teams.  Various timber deterioration mechanisms will be explained.  The group will come together at the end of the assessment period to discuss the overall condition of the structure and explore any recommendations for repairs.


Ron Anthony

Ron Anthony received an M.S. in Wood Science and Technology from Colorado State University.  His wood consulting activities have focused on the application of inspection technologies for assessment of wood in historic structures.  Typical projects in Colorado include the Hanging Flume, Reiling Dredge, Paris Mill, Evans School, Elitch Theater, Foxton Post Office, and the McElmo Flume.  He also conducts workshops and lectures on wood properties and the use of wood in construction applications.  Mr. Anthony is the 2002 recipient of the James Marston Fitch Foundation Grant for his approach to evaluating wood in historic buildings; he is a Fellow in the Association for Preservation Technology International (APTI), and a recipient of APTI’s Harley J. McKee Award. 

Brian Malone

Brian Malone is a licensed structural engineer with KL&A Structural Engineers and Builders.  He received a dual M.S. in Civil (Structural) Engineering and Wood Science from Oregon State University.  With a focus on wood structures and the application of wood science to structural design, Brian’s projects include heavy timber, mass timber, existing and historic structural assessment and renovation, civic buildings, and custom residences.  Prior to his career as an engineer Brian was a professional carpenter and built and restored traditional timber frame structures throughout the country.  He serves on the Executive Committee of the Timber Frame Engineering Council.

Assessments Workshop

Friday, May 17, 1-5pm
Emerson School, 1420 Ogden St, Denver 80218

$65/$50 for CPI Members
Capped at 35 individuals

Historic Structure Assessments are critical first steps in the preservation of historic sites.  We are fortunate in Colorado that History Colorado is very supportive of these efforts.  A thorough assessment requires a variety of tools and team members working together for a preservation plan to guide further work.  A systematic approach is key to understanding the building.  This workshop will explore strategies for the development of Historic Structure Assessments following the Section 3 Scope of Work outline used by the State Historical Fund.  Where to start, what to look for, what methods to use, and how to pull it all together will be explored.  The workshop will be held in a host historic structure.  We will start altogether with a discussion of what a Historic Structure Assessment is, an overview of tools that can be used for non-destructive testing, and a brief description of the host building.  Participants will then break into small groups and tackle major building components as follows: site work, foundations, structural systems, exterior walls, roofing and drainage, exterior doors and windows, interior finishes, mechanical and electrical systems.  Experts will work with each group to develop descriptions, condition assessments, and recommendations. Emphasis will be put on proper identification of materials and systems and the determination of the actual causation of identified deficiencies.  At the end of the day, we will come back together to prioritize our recommendations and create the preservation plan for our host building.  Come join us to learn how to put together one of these important reports.

Masonry Workshop

Friday, July 26, 1-5pm
Building Restoration Specialties
3060 Walnut St, 80205

$65/$50 for CPI Members
Capped at 25 individuals

Masonry was used in many historic structures. Understanding the original construction materials is the first step in the selection and specifications of appropriate repairs. A suitable repair for marble is not the right choice for granite. This session will present typical Colorado building stones and brick masonry types that you are likely to run into as you restore buildings throughout Colorado. A walking tour of a historic neighborhood will provide an opportunity to identify the materials in a real environment.  Following the tour, participants will gather at a masonry salvage yard. A brief discussion of the history of quarries and where these stones were sourced will be included. Example stones will be found throughout the yard so participants can handle the various materials. The other essential component of a masonry structure is the mortar. An example of mortar analysis will be presented and participants will have the opportunity to work on replicating the sample using different materials including mortar pigments and different sands. Mortar joints can be finished in many different ways, the essential concepts of repointing will be discussed along with an opportunity to practice joint profiles such as beaded and vee. Dress in work clothes!

Featured Project

Preservation for a Changing Colorado

The 2017 update, Preservation for a Changing Colorado, resulted from a partnership between Colorado Preservation and History Colorado and Colorado Preservation, Inc. Prepared by Clarion Associates, the new report and accompanying website document the economic benefits of rehabilitation projects, analyzes property values and neighborhood stability in local historic districts, and summarizes the increasing impact of heritage tourism, private preservation development and the success of Colorado’s Main Street program. In a key finding, researchers found that for every $1 million spent on historic preservation in Colorado leads to $1.03 million in additional spending, 14 new jobs, and $636,700 in increased household incomes across the state! The 2017 report also considers the important role preservation plays in helping Coloradans provide new spaces for creative communities and co-working, create and sustain meaningful places, respond to the state’s changing demographics, and address climate concerns.
