2010 AIA Springfield Design Awards

By: Christophwer Swan, AIA

Last night BR&P was presented a Merit Award for our restoration project of the historic First Church of Christ, Scientist located in Midtown Springfield.  The Professional Jury bestowing this award sponsored by AIA Springfield consisted of Anne Marie Decker, AIA, Principal with Duvall Decker Architects, P.A., Roy T. Decker, AIA, Principal with Duvall Decker Architects, P.A., and David Cronrath, AIA, Dean of LSU College of Art & Design at Louisiana State University in Baton Rouge.

I see this award as icing on the cake because it was already a success for a number of reasons.  It is extremely rewarding to have worked on a project where there was great collaboration between the Owner and the Architect joining forces to preserve a great building. The project was on time, on budget, and completed $6,400 less than the bid amount.  Why was this project so successful?

I believe the first reason is that the Owner, the City of Springfield, hired us before they even knew what they wanted to do with the building.  We were initially consulted to conduct a thorough investigation into the building to document the scope of the preservation, environmental studies, a structural analysis, and a cost estimate for the stabilization of the structure.  This was compiled into a booklet that was eventually used to formulate the scope of the work for the stabilization and restoration of the building. 

I believe the second reason for the project’s success is that the City of Springfield worked with Butler, Rosenbury & Partners to space plan several potential tenants for the building.  There were a number of City offices that needed a new home and we programmed and evaluated the feasibility of each tenant for the space.  We looked at everything from traditional offices to a TV studio.  It was finally determined that the historic structure would be the new home of the Springfield-Greene County Health Department – Environmental Services Division. 

I believe the third reason for the project’s success was a conscience effort to anticipate the unexpected.  Any time you renovate and existing building, there will be surprises that arise during construction.  The impacts of these surprises were minimized by having a clear understanding of how the building was originally constructed and anticipating potential areas where changes orders might hide.  A careful balance of allowances, unit prices, and minimum bid quantities were established in the construction documents and ultimately saved the City of Springfield thousands of dollars in change orders. 

I see this project as a benchmark for all of my projects.  It is imperative to meet the technical requirements of a project such as budget, time, and accuracy, but it is even more rewarding to meet those requirements while preserving a cultural resource, giving those buildings a new purpose for years to come, and being recognized by your peers for excellence in design.

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' Stable - Entry Four

By: Lindsay Barcomb, LEED AP

It's a rainy Sunday afternoon when I sit down excitedly to piece together a puzzle that's been hiding away in my closet, patiently waiting for me to find time to unify its scattered pieces. I only have one problem, some of the pieces are missing and I'm not entirely sure what they look like or even how many are missing. On Monday, a similar puzzle awaits the Simmons' Stable project team.

We start with a ghostly shell of the stable, precariously learning this way and that. The stable is rich with character, yet precious details have been lost to time, ravaged by weather, neglect or maybe just a horse that didn't know better. We document what is left of the scattered pieces and begin putting the puzzle back together.

The goal for the project is to restore the stable to the 1940s era. This period follows a major remodel of the stable and its purchase by namesake Arthur Simmons. In order to preserve the integrity of the stable, we focus our initial research more broadly, researching the time periods before and after the period of restoration. We utilize invaluable public resources, which help to define the scope of the project. Among others, these resources include the National Parks Service Preservation Briefs. These briefs cover a wide variety of specialized topics relating directly to the preservation and restoration of historic buildings and building elements.

On a local level, we comb the collections at the Audrain County Historical Society which contain a wealth of photographs and newspaper articles featuring the stable. We further refine our research, consulting local residents and memoirs, include Jane Simmons' Arthur Simmons American Icon of the Horse World.

As we delve deeper in our research, we get a more precise grasp on the true bones of the project, including the details unique to the Simmons' Stable. Once we've exhausted our external resources, we head straight to the source - Simmons' Stable.

With an abundance of information, we compile all of our research into a single document: a record of the project and processes which includes an assessment of the structure, its history, architectural details and evolution of the stable. Once these items are outline, the design team proposes a plan of action, highlighting those elements most critical to the restoration and which impact the immediate stabilization of the structure. The document provides an outline of both the scope of work to be completed and the processes involved. Serving as an invaluable resource to the owners and the design team, it also serves as a great tool to many others.

After the document is complete, it is presented to the many bodies governing the restoration of the Stable including the Simmons' Stable Preservation Trust, the National Parks Service, and the State Historic Preservation Board among others. It's also utilized to inform the public regarding project development and ongoing fundraising efforts.

In subsequent articles, the project's structural engineer, John Miller, and I will outline the development of the project through the remainder of documentation and construction in the remaining entries.

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.
