Earthbuilding in the Big Apple … Who Would Have Thought!

A call from the Polo Corporation leads to laying earthen floors in New York City
by Richard Connerty - R. P. Connerty and Son Construction Co.

Several years ago I received an intriguing phone call; “Mister Connerty, my name is Doug Hockmeier and I’m with Polo Corporation here in New York. We were wondering if you might be able to come to our showroom here in the city and install a mud floor for us.”

During the course of the call, Hockmeier went on to explain that his boss, Ralph Lauren, was developing a line of homewares such as sheets and towels with a Southwestern motif. And, as a stickler for providing an accurate environment for these products, Hockmeier said, “Ralph expects the real deal for the display… mud plasters, mud floors, Southwestern furniture, navajo blankets, and so on. Buyers come from all over the world to this annual show. And it’s on the sixth floor of the Polo showroom … on the sixth floor! Can you do it?”

I gave this proposal some serious thought and considered many factors. Firstly, I felt certainly knowledgeable and competent in laying mud floors. My company, R. P. Connerty and Son Construction Company, had laid several earthen floors and I had full confidence in our ability. We had further volunteered on a Cornerstones project, restoring an number of deteriorated capillas and moradas in Northern New Mexico; and, in the process, we had learned a great deal under the leadership of two experts, Sam Baca and Ed Crocker. And finally, I knew that with my son and brother in-law, I had the skilled labor to undertake this endeavor.

Now, before formally accepting, I needed to figure out costs and procurement possibilities for undertaking such a job in Manhattan. Hockmeier had presented me with the square footage requirements of the floor plan, and, based on calculations, I realized that I need about six cubic yards of a clay and sand mix. Now, I’m originally from Boston but I knew New York fairly well as I had lived there for several years before moving to Santa Fe in 1978. In fact, when living in New York, I drove a cab and had a good idea of happenings of this city and how one gets things done.

So what did I do? First, I put in a call to my old friend Sweeney with whom I had co-owned a small bar on the lower East side back in the day. I explained my venture and that I need a truckload of clay and sand mix delivered to the showroom of Polo Corporation at Broadway and 38th. Sweeney replied, “Let me get back to you. My cousin Timmy works as a groundskeeper at Shea Stadium and I think he’ll be able to hook you up!” And, indeed, he did. Sweeney followed up with a call, saying “You need to talk to the DiFrancini brothers. They have a sand and gravel business in Flushing and they provide the clay mix for the infield at Shea. They specialize in clay tennis courts and baseball infields.”

With this information, I phoned to Ray DiFrancini who assured me that he could deliver the six cubic yards of material at a reasonable price. Following this, I called Hockmeier back and offered him a cost figure for the work to which he quickly agreed. In fact, he agreed so quickly that it made me wonder if I had underbid the job.

Nonetheless, two weeks later my brother-in-law, Kevin, my son, Eamon, and I were off-loading a dump truck at the service entrance of the Polo Corporation, shoveling the clay-mix into wheeled metal bins, taking it up the service elevator, and onto the showroom floor. It is there where we mixed the dry ingredients and water in wheelbarrows.

The newly installed mud floor looked nice and the design staff of Polo Corporation were very happy with the result. The only hitch was that, as with all mud floors, they sometimes take a couple of weeks to completely dry out and time was limited. As it happened, while the drying was happening, other contractors walked back and forth over our mud floor. This created an aged patina that looked terrific.

As for me, the best part of the job was that Eamon and I got to spend some memorable time together along with my dear mother-in-law, who lives on the Lower East Side, and who put my son and I up for the seven days that it took to do the job.

And once again, Hockmeier and others at the Polo Corporation liked it. How do I know? They paid us in cash!

So there it is … a phone call from the Polo Corporation leads to a mud floor in the Big Apple! Don’t let anyone ever tell you that earthen construction is limited to the Southwest!

TIMELY NEWS

San Antonio Passes New Earth Construction Permit Codes

The Right Time for Code Change: How Earthen Construction Initiative helped San Antonio become the first U.S. municipality to adopt IBC-based amendments on Earthen Construction
by Lauran Drown, AIA

In June 2018, San Antonio City Council voted unanimously to approve the adoption of the 2018 International Code Council (ICC) Building-related, Fire and Property Maintenance codes and corresponding local amendments. In San Antonio, adopting the latest ICC codes occurs every three years following the three-year update cycle of the ICC. What was remarkable in 2018 was that included among the local amendments was language related to the use of earthen materials in building construction. This made San Antonio the first municipality in the United States to adopt International Building Code (IBC) -based amendments on earthen construction (EC).

The adopted amendments, which comprised changes and additions to IBC Section 2109: Empirical Design of Adobe Masonry and to corresponding definitions in IBC Chapter 2: Definitions, were put forth by Earthen Construction Initiative, a San Antonio based 501c3 organization devoted to advancing and promoting earthen construction. ECI was motivated to take this on when in February 2018 at a member’s meeting, San Antonio City Councilman and architect, Roberto Treviño asked if it would be helpful to have more representation for EC in the local building code and pledged his support of an ECI-sponsored proposal during the then ongoing ICC adoption process.

Between February and May, the five-member ECI technical committee chaired by Michael Donoghue, PE of Austin, TX, met regularly to research current codes on EC, develop a proposal strategy, and craft language suitable to regional conditions as well as to a potentially wider U.S. audience.

Ground work for ECI’s proposal was laid by The Earth Builder’s Guild (TEG) in the previous ICC cycle. Prior to its 2018 publication, IBC Section 2109: Empirical Design of Masonry dealt primarily with fired masonry and contained only a few provisions about earthen construction. Due in great part to the preference for frame buildings with masonry veneer, the chapter had seemingly become defunct causing it to be considered for deletion. Present at the ICC hearing where this matter was discussed, TEG members realized the possible tragedy of losing a nod to EC as an opportunity to successfully propose a rewrite of Section 2109 based on successful language from the New Mexico Earthen Building Code.

Having this language already in the IBC, provided a point-of-origin for ECI’s proposal and for discussions with officials at the City of San Antonio’s Development Services Department. Prescriptions that would guide officials on how to interpret code to adequately inspect earthen structures was a tangible concern as several rammed earth or compressed earth block (CEB) structures had in recent years been built within city limits. Development Services officials aided ECI with their feedback and with help navigating the formal amendments process.

Considering adobe, CEB, and rammed earth as the primary technologies that would most often be used locally, ECI’s proposal centered on developing language applicable to all three. Chapter 2109 in the San Antonio Building Code is now aptly titled, Empirical Design of Earthen Construction. The new code went into effect on October 1st. A summary of the changes is available on the City of San Antonio’s website at https://docsonline.sanantonio.gov/FileUploads/DSD/CI2018-001.pdf.

Lauran Drown, AIA is a founding member and the current vice president of Earthen Construction Initiative. She is a Texas-registered architect employed with Wiss, Janney, Elstner Associates, Inc. where she specializes in building enclosure consulting for contemporary and historic buildings.


REGULAR COLUMN: GETTING THE DIRT ON ...

Getting the Dirt on Kirk Higbee

1. How did you get involved in earthbuilding?

In kindergarten, I toured the old adobe Fort El Pueblo in my hometown, Pueblo, Colorado. The lifelong interest, passion, and quest for knowledge in earthen buildings and methods had begun. In the years that followed, I visited Bent’s Fort, another massive adobe structure which was rebuilt near La Junta, Colorado. Spending many years walking around the empty space where it once existed, I saw first hand and from practitioners how the massive fort was rebuilt.

Additionally, I volunteered at Fort Garland, another adobe fort on the western side of the Sangre de Cristo Mountains in Colorado. In my free time, I regularly searched out adobe buildings as well as adoberos in my hometown and learned a number of things that continued to pique my interest in, and knowledge of, adobe building.

2. What you currently working on?

I have been working on a number of projects. Current endeavors include working on my own adobe house in Phoenix, Arizona. This has required me to search for the city’s adobe building codes as I was met with dead ends at the Building Department. 

Secondly, I have been working with a number of other individuals on projects. For example, this past summer, I assisted in the construction of an adobe hogan on the Navajo Nation for an extended Navajo family. Furthermore, I have been volunteering with Brick by Brick, a compressed earth block project in Scottsdale, Arizona. And I have been helping a number of neighbors who need basic instruction on how to simply and affordably maintain their adobe homes.

Thirdly, I am experimenting with a common weed that produces a latex sap for use as a stabilizer. Trials of the plant have so far proven effective. 

And lastly I continue to add to an annotated bibliography of adobe and earth building resources that I began several years ago. At this point, the bibliography includes nearly 12,000 sources. To make it more accessible to practitioners and scholars, I have begun to rank the top 50 sources — journals, books and movies — in various earthbuilding sub-topics such as mud plasters, rammed earth, cob, and earthquake stabilization for adobe. 

3. Where do find your passion in this field?  For example, are you particularly interested in the community building, cultural, economic, engineering, environmental, regulatory, or sociological aspects of earthbuilding?

My passion for the field is in building infill housing in large cities of the Southwest where adobe architecture is or has existed. Infill is building on vacant lots in already established or transitioning neighborhoods. 

Another passion or goal would be the construction of sub-divisions or housing developments across the Southwest. My passion for earthen architecture is rooted in the local economy using locally available resources: earth, laborers, and building materials.

4. Within earthbuilding, where do you see important contributions coming from in the future or likewise where do you see earth building going?

Future contributions in earthbuilding will come from space travel. For example, out of the Apollo space program to the moon, artificial joints were developed. In space, joint hinges cannot be oiled as the oil would float away. The same principle is seen in artificial human joint, as oil cannot be applied or be present in our bodies. On planets, there is a limited amount of space and resources for building materials. Yet, we need only look to what is present. For example, on Mars, the soil is readily adaptable for soil construction. The science behind seismic engineering, thermal resistivity and capacitance, along with durability and resilience are all the same needs that exist on earth. 

Young scientists and engineers are relearning about earthen construction because of the excitement of space travel and colonization which will aid greatly, at least in my view, earthen construction on earth!  Additionally, there are those throughout not only the United States but the world who are currently making advances on 3D earthen printers, on the thermal factor of earthen architecture, and on the resilience of earthen architecture … these are all current factors affecting earthbuilding.

5.  Why is it important that the general public become more educated about earthbuilding?

Earthbuilding helps the local economy through jobs, technological training, sourcing local building materials, using less energy to heat and cool our homes, and living in cleaner nontoxic spaces that often leave no carbon footprint!

Each issue we feature an individual in the earthbuilding field. If there is someone you think would be wonderful for us to interview, or about whom you would like to know more, please let us know by emailing the editor of EarthUSA News at editor@adobeinaction.org.
