At 289 feet tall, the dome of the United States Capitol towers over the eastern end of the National Mall in Washington, D.C., an instantly recognizable symbol of democracy. The cast iron dome itself was completed in 1863, after the nation’s rapid growth necessitated a remodel and expansion of the entire Capitol in the 1850s.
By the 1950s, however, the 9 million–pound dome had numerous fissures, and an attempt to weld them during a 1959–60 restoration was largely unsuccessful. The entire surface was cracking by 2014, prompting a three-year project that was completed in time for the 2017 Inauguration.
Vertical Access helped to document 1300 cracks on the United States Capitol Dome.

Last week, architects, engineers, and preservationists made the trek to Salt Lake City for Mesa to Mountain: Preservation in the American West. The three-day symposium, hosted by the Rocky Mountain Chapter of the Association for Preservation Technology International, drew audiences and presenters from New England to the Pacific North West. Vertical Access’ Kent Diebolt and Kristen Olson served on the Planning Committee. VA technicians Patrick Capruso, Kevin Dalton, and Keith Luscinski also attended.
Mesa to Mountain opened at the historic Alta Club with a reception and plenary session presented by Peter Goss, Ph.D. on architectural typologies found in the Beehive State. The symposium moved across South Temple the following morning to the Joseph Smith Memorial Building where Lee Kreutzer, Cultural Resource Specialist for the NPS National Trails System, delivered her keynote address, “Paths, Pathogens, Ponies, and Wheels: How Trails Changed the Cultural Geography of America.” Kreutzer’s overview provided context for the paper sessions which focused on seismic mitigation, materials, and cultural heritage. Presenters offered talks on a variety of subjects specific to western architecture and preservation ranging from the influence of midcentury precast concrete in the Rocky Mountain Region to documenting the decorated earthen plaster and wood of a 12th century kiva at Utah’s Bare Ladder Ruin. Mesa to Mountain’s regional focus lent a sense of relevance to the paper sessions with common threads woven through each presentation.
Those same themes were apparent during the field sessions offered on the third day of the event. Whether it was a trip to Antelope Island State Park to catch a glimpse of bison and pronghorn sheep while exploring an 1848 adobe ranch house, touring the shop at Historical Arts and Casting, one of the nation’s premier metal casters, or viewing the base isolators at the Utah State Capitol Building and the lattice-truss arch system at the Mormon Tabernacle each session reinforced information presented the day before. The Mesa to Mountain Symposium was a success due in large part to its historic venues and regional focus.

On a recent trip to Peru I had the opportunity to visit some of the ruins at Chan Chan, located in La Libertad province around the city of Trujillo. Built around 1200, Chan Chan served as the capital of the Chimu Kingdom until falling to the Incas around 1480. The city covered 20 square km, was the largest pre-Columbian city in the Americas and a monumental example of earthen architecture. At its height Chan Chan is believed to have had a population of around 60,000 people.
Due to the consistency of the swells in nearby Huanchaco, I was preoccupied with surfing for most of my time in the Trujillo area and only visited the Tschudi Complex, a relatively small section of the Chimu city. In all the city consisted of 9 walled citadels, or palaces, so there are several more interesting sights worth visiting.
Preservation efforts at the Tschudi Complex, which is the only section of Chan Chan that has been partially restored, are ongoing. Most of the architectural details are modern recreations though there are a few originals that remain. Due to its geographic location on the northern coast of Peru the ruins are susceptible to erosion from the heavy rains brought on by the El Niño phenomenon so much of the Tschudi Complex is now covered by a protective roof structure, which I found to be interesting in its own way. Upon returning to Huanchaco I immediately recognized some of the same architectural motifs at the Instituto del Mar del Peru, Laboratorio Costero de Huanchaco.
Besides being an important cultural site I think that Chan Chan is also a powerful example of ecological construction. It’s interesting to see how a 500+ year old city constructed of locally sourced, earthen material slowly returns to it’s original form leaving almost no trace of it’s existence. Try to imagine what a modern city will look like 500+ years from now.

In October, Technical Services staff visited the Dutch Reformed Church in Newburgh to check in on an important step forward for the structure. The church, built in 1835, was designed by Alexander Jackson Davis and is a National Historic Landmark. The League named the Dutch Reformed Church a “Seven to Save” site for 2016-17 and is working with the City of Newburgh and local preservation advocates to make a stabilization, preservation, and re-use plan for the building.
In 2012, the sanctuary ceiling collapsed, crushing the pews inside and destroying additional important interior features. Because the condition of the building rapidly declined after the ceiling collapse, a complete structural analysis of the upper trusses and roof was absolutely necessary in developing a plan to save the building. But how could we complete this inspection and analysis when the building’s condition was so dangerous?

Last week the Archdiocese of Philadelphia issued an order to pastors and religious officials baring all involvement in placing churches on the Philadelphia Register of Historic Places. Patrick Hildebrandt, founder of the Philadelphia Church Project, says the rigid edict wages war on historic Catholic church survival and preservation.

Predicted by its organizers to be the “greatest single event in history,” the 1964-65 New York World’s Fair was indeed a spectacle. One of the most notable structures of the Fair, and one of the few that still stands, is the New York State Pavilion. Looking to create a symbol of progress and to show off the state’s status as host of the Fair, Governor Rockefeller commissioned Philip Johnson, who worked with structural engineer Lev Zetlin, to design the New York State Pavilion. The pavilion was in fact an assemblage of three separate structures: the open-air Tent of Tomorrow, three interconnected Observation Towers, and the circular Theaterama.

The Tent of Tomorrow was used for several years after the end of the Fair in 1965, first for music and art shows, then as the “Roller Round Skating Rink.” In the summer of 1974, the City closed the tent structure, citing the “hazardous condition” of the Kalwall roof panels. The multicolored roof panels were removed in 1976, leaving the structure in more or less its current state.
Although unused for over forty years, the Tent of Tomorrow is showing new life thanks to the work of New York area painters. The City of New York Department of Parks and Recreation (DPR) who owns the structure, teamed with the New York Structural Steel Painting Contractors Association and the International Union of Painters and Allied Trades, Local 806 (Structural Steel and Bridge Painters of Greater New York) to complete a spectacular painting project during the summer of 2015.
Labor for the painting project was donated through apprenticeship programs of the trade groups. Funding to provide meals for the crew during the work was raised through crowdsourced funding. The paint job not only returns the steel elements of the Tent of Tomorrow to their original appearance, it also helps to protect the structure from continued corrosion and deterioration. The painting project is one step in the long process being undertaken by DPR and the borough of Queens to stabilize and hopefully one day restore the Tent of Tomorrow and Observation Towers of the New York State Pavilion.

A recent article in the Daily Commercial News describes the process of rehabilitating historic buildings – called heritage buildings in Canada – and mentions Vertical Access’ investigation of One King West, the former Dominion Bank Building in Toronto, Ontario. The article recaps a seminar presentation by Sarah Gray, managing principal with Halsall Associates, our client for the One King West project.
Ms. Gray highlighted the importance of archival research, testing, and inspection in the early stages of a repair or rehabilitation project. For One King West, Vertical Access provided a hands-on inspection and documentation of building conditions using TPAS™, the Tablet PC Annotation System. TPAS is now being used for the construction administration of the rehabilitation of One King West, demonstrating the flexibility and adaptability of the software for a variety of documentation and reporting needs.
The article, entitled “Heritage envelope rehab a balancing act”, was written by Dan O’Reilly and was published on January 5, 2015.
