Progress in Process: Park Central Square - Entry 1

By: Frank Zanaboni, ASLA

It has finally happened. I know officially it starts on March 20th, but for me spring starts when the two magnolias in my front yard bloom. Over night all of the dormant buds opened and this morning the shrubs were covered in a beautiful deep magenta. After the magnolias bloom, the redbuds will bloom down in the valley and shortly after them, all the trees, the walnuts, hickories and oaks will leaf out and then we'll be racing on to summer.

As spring fever hits the Ozarks, so does gardening fever. Everyone gets out in their yard for spring cleanup. Now is the best time to think of ideas that can help make our yards, our outdoor environments, more usable, interesting and fun.

Personally, I live on 18 acres - part forest and part meadow with a lazy creek running through the middle. I have a never-ending list of projects that keep me busy. Most days, just following the ebb and flow of Mother Nature as she does her thing in the Ozarks is all I can do - mow a little bit here, plant some trees and flowers and really just sit back and watch.

Professionally, I enjoy working on projects that are mainly in the urban, man-made and controlled environment. Mother Nature has long since been paved over and now I am challenged with bringing bits and pieces of her back in manageable little "pockets." My main "pocket" as of late and one that I have been working on for more than two years is Park Central Square in the heart of downtown Springfield, MO. Last year, we wrapped up the design and construction of the streetscape around the outer square. This included replacing the sidewalks and ceilings over basements, upgrading the lighting, adding potted flowers and trees, (I'll talk about these items more in a future segment) and my favorite element - the removal of the 6" curb which was replaced with a ring of bollards and tactile warning tiles. This element is so important in helping to allow pedestrians better access throughout the square; especially for access into the inner square.

Currently, I am working on the inner square. Our schedule is aggressive but doable. We are going to refine design and construction documents by mid-May, bid through mid-June and start construction at the end of July. Construction is scheduled to be complete by the beginning of Spring 2011.

We are right in the middle of working out all of the unknown challenges involved in the rehabilitation of the historic outdoor space. Park Central Square is:

  • A space designed by someone who did not live here
  • A design that has lost some of its original elements due to its uniqueness
  • A design that has felt the pressures of urban use and diminishing maintenance budgets
  • A space now full of challenges and opportunities

Follow me throughout the next few months as I share our struggles and successes, and our thoughts and ideas as we work to transform the square back to the historical center of Springfield.

Simmons' Stable - Entry Five

By: Lindsay Barcomb, LEED AP

A multitude of injuries have pulled star athletes out of the game. Benched, people soon forget about the star that was once their hero. But some fans never falter, urging their hero to push on and return to the game. Following weeks and months of intensive rehabilitation, the athlete makes his return. Although he looks the same, he is now stronger, more agile. Like the injured hero described above, Simmons' Stable, once the commanding star of the Saddlebred Horse industry, needed loyal devotees and loving therapy to bring it back to its former glory. The Simmons' Stable Preservation Fund was such a loyal fan, championing through numerous challenges and naysayers to save the Simmons' Stable and give it new life.

After careful examination of the project and work to ensue, it became clear that restoring the 252 foot stable to its former glory would be a multi-phased process, focusing on each injury the stable incurred over time. The complete preservation and restoration process required that early on, we gather the teams involved and prioritize the process of rehabilitation. Most critical to the health of the stable was the stabilization and protection of the structure, as previously detailed by John Miller. In this entry, I'll detail the processes of protecting the revitalized structure, while preserving its historic integrity.

The first item to be restored was the roofing. Layer-after-layer of asphalt roofing shingles were stripped from the tired structure. A new shingled roof, matching that from the beginning of Arthur Simmons' reign over the horse world, soon protected that restored structure from the rain and snow which ravaged the wounded structure throughout the years. Once the roof and structure were reconditioned, the remainder of the building's exterior was to be restored.

Although budget constraints dictated that the stall windows be restored at a later date, custom-fabricated dormer windows were installed to replace the originals which had been damaged beyond repair, twisted apart by the failed structure and years of harsh weathering. At the south gable end of the structure, the unique combination of shingles and shakes were restored, resulting in assorted rows of square, diamond and fish-scale shingles. At the east and west facades, plywood that was first installed in the 1970s was removed and replaced with horizontal siding. The new horizontal siding and watertable replicated what was captured in photographs from the 1960s and earlier. Vertical siding, twisted and bent by time, was carefully removed and salvaged to allow correction of the structure. After the structure was realigned, the once warped siding was reinstalled and repainted. The stable soon began to look like its former self, the star of the Saddlebred Horse industry.

As Mexico and its residents began to take notice of the new construction; the began to pay attention to the once forgotten derelict stable. Curious residents would wander up to the stable, asking questions or merely staring in wonder as the stable transformed before them. Throughout our many visits to the stable, John and I met several such characters, kind strangers who offered prayers, cool beverages on hot summer days, or a bucket so we could rest our legs after a long day.

Nearly complete with the initial phase of restoration and with the addition of a few simple block letters painted in black, the stable embodied a minor renaissance. From Boulevard Street, passers-by could now clearly read the words: SIMMONS'S STABLE, a victory for the town and those who had worked so hard to save a forgotten star of the horse world, an era passed and a world apart.

A Structural Engineering Account of Simmons' Stable Restoration

By: John Miller, PE, SE, LEED AP

One of the challenges that face structural engineers on a historical preservation job such as Simmons’ Stables is balancing the interests of the stakeholders in the project.  In this case the stakeholders are the owners, preservation authorities and the building officials.  The owners and preservation authorities would like to see the building returned to its original condition and the building official wants to make sure that it meets the intent of the building code.  One of the great things about this project was the fact that each of the parties came to the table with open minds and a focus on solutions and moving the project forward, rather than being stubborn on preconceived notions.  

This structure is not only unique in the history of its function, but also in the materials that were used to construct the barn.  The materials were dimensional lumber; similar in size to what is used today that can be bought at any Lowe’s or Home Depot.  Typically, lumber in buildings of this age were built with rough sawn material that varied in size as each mill had their own standards. 

In 1877 there were no building codes, each craftsman was a master of their trade and an owner would hire the contractor who would then erect the structure.  Simmons’ Stable was no exception to this and it has stood the test of time for the past 100 years, with the maintenance that was done, meant to band-aide the problems to pro-long the function.  It is a utilitarian structure and was treated as such. 

One of the first challenges was the fact that there was no permanent foundation for the structure.  When we first visited, some of the frames had settled as much as 18 inches, partially due to lack of foundations and partially due to decay of the bottom of the posts.  One of the committee members that worked at the barn told us that some of the stones that supported the posts were removed because the horses would hit their hooves on them.  Another issue was in the framing itself, the roof rafters were 2x4 members that spanned approximately twelve feet, without collar ties or a center ridge beam,  They would cantilever off the frame at the face of the stalls and bear against the opposing rafters.  As the building shifted, the connections of the rafters failed and the roof dropped and pushed out on either side.  The final issue was the lack of lateral bracing in the building to transfer the lateral loads from the roof diaphragm to the foundations.

The engineering challenge came in the manner in that the building was framed.  It was originally a combination of post and timber frame methods with stick built infill.  The roof was stick built utilizing 2x4 rafters that bore at the outside wall and hayloft beam and then supported against the opposing rafter at the ridge.  There was no apparent bracing in the short direction of the building and as the building settled and deteriorated the ridge and roof framing relaxed causing drops in the ridge line as much as several feet.

After a brief analysis of the structure we realized that we could not simply replace the framing that was there, but would have to provide a structure that met two goals, be true to the intent of the original construction and satisfy the life safety requirements of the current building code.    

     

 

We decided that the refurbished structure would meet both criteria, be true to the original intent and meet current building codes.  One of the first things we did was to modify the roof framing both at the main roof and dormers.  We replaced the 2x4 rafters with 2x8’s.   We also installed a ridge beam and collar ties to improve the stability of the rafters and ridge line.  We reinstalled skip sheathing, but added a plywood diaphragm over the top to provide a diaphragm.  At the dormers we installed some engineered wood beams with steel flitch plates, but cladded them with dimensional lumber in an attempt to be true to the original appearance.  

To brace the building we used a series of tie rod braces and custom manufactured steel brackets at each stall line where they would not be visible we used light gauge steel strapping.  

 Simmons’ Stable was definitely a team effort with the owner, contractor, architect and engineering. The final product accomplished the two goals we set out with, be true to the original structure, let it tell the story and be a structure that is safe.

Simmons' Stables - Entry Three

By: Lindsay Barcomb, LEED AP

Simmons' Stables is interlaced in the rich fabric of many great pasts. It's a critical piece of local, state and national history, contributing significantly to the development of Saddlebred history as well as the early history of the African American horseman, Tom Bass.  The great legacy makes it a perfect candidate for a public-private partnership to fund the restoration and conservation of the structure.

Project Funding

In 2002, the Simmons' Stable Preservation Fund was established to protect the Simmons' Stable. Within two years, the Fund secured Neighborhood Assistance Program tax credits from the Missouri Department of Economic Development. These tax credits helped spur donations from local, state and national contributors totaling $500,000. Late in 2004, the stable was placed on the National Registry of Historic Places. Listed as the Arthur Simmons' Stable Historic District, the site was awarded a Save America's Treasures matching grant of $250,000 in 2005.

Implications of Public and Private Funding

Multiple funding sources are a dream for those trying to make the impossible possible, however, they create a unique challenge for the design team. Before a project can begin it's necessary for the project team to understand the heightened level of coordination, analysis and documentation. It's also vital for the project team to develop an acute awareness and sensitivity to expectations.

As a historical landmark, the Simmons' Stable is not only a great historical structure, but also a significant component to local heritage. It is essential for the project team to consider the impact on the local community, as well as their personal ties and expectations. The community of men and women who interacted with these structures in their work, play and daily life becomes a client. While it is often difficult to balance the unique expectations of these individuals, they are a tremendous resource for the design team.

In addition to requiring a heightened sensitivity to local expectations, projects like Simmons' Stable also require a sophisticated level of coordination. Each funding source has its own unique guidelines for documentation and mangement from start to finish. While each party may share similar goals for the ultimate development of the project, each outlines its own responsibilities, means and methods. Funded through multiple entities, the Simmons' Stable had three distinct funding sources each requiring varying levels of management.

The Neighborhood Assistance Program tax credits, administered by the Missouri Department of Economic Development, required minimal documentation and coordination from the design team. The requirements of the tax credits were managed by the Simmons' Stable Preservation Trust and included quarterly reports, a final report and an audit of the project resources.

Comprised of passionate locals, the Simmons' Stable Preservation Trust represented both private and public interests. This team managed the funding resources for the project and served as a compass of local interests and concerns.

The National Parks Service, administrator of the Save America's Treasure grant, was an active participant in the process from start to finish; although, most participation occured in the initial project processes - including documentation and analysis of the Simmons' Stable.

A significant portion of funding administration is tied to the documentation and analysis of the historic structure. this intensive process is perhaps the most significant element of a historical restoration project. Next week, I'll detail the processes behind this careful analysis and documentation of the Simmons' Stable.

Simmons' Stable - Entry Two

By: Lindsay Barcomb, LEED AP

Driving down West Boulevard, it's hard to miss the large white stable that sits just 40 yards off the road. Not far from the city square, it's nestled among quiet homes, a bustling elementary school and a scattering of civic structures. Many who reside in Mexico know of the stable's former glory; others who see it in its shambled state, worn by weather and time, must imagine a modest past. Few probable know the complex and fantastic history that surround the once proud Simmons' Stable.

Its story begins in 1887, when the Clark and Potts Combination Sales Company erected the historic structure. Early in its history the stable produced some of the world's finest Saddlebred horses, helping give Mexico its distinction as Saddlebred Horse Capital of the World. Celebrated African American horseman and trainer Tom Bass once worked at the stable, training horses whose lineage can be traced to some of today's finest show horses. Admired both at home and abroad, Tom Bass was invited to demonstrate his artistry in a command performance for Queen Victoria's Diamond Jubilee in 1897.

Even after Tom Bass's time, the stable continued to figure prominently in the horse world. Horses auctioned from the famous stable found notable homes with both recent and past celebrated personalities, including: American Presidents, movie stars like William Shatner and W.F. "Wild Bill" Cody who featured the horses in his Wild West shows.

Today, the stable bears the name of its latest owner, Arthur Simmons. Arthur Simmons purchased the stable in 1943 following a remodel that transformed the stable to the iconic edifice we recognize today.

The Simmons' Stable Preservation Trust, comprised of a small group of passionate locals, was recently established to preserve and restore the Simmons' Stable, its six-acre site and neighboring structures; including two additional stables, a Farrier's shed, a storage shed and two grain bins, and the Arthur Simmons' Residence which sits adjacent to the property. A large component of the Trust's funding for the project came from public funding. Next week, I'll discuss the implications of public and private funding on the historic project and process involved.
