State of Missouri Current River State Park Renovation and Expansion

Current River State Park, listed in the National Register of Historic Places, began its life as the Alton Club, a summer retreat for the employees and customers of the Alton Box Board Company. Constructed circa 1937-1945, the park’s lodging and recreation facilities are quintessential examples of the rustic architecture promulgated by the National Park Service and Civilian Conservation Corps during this era.

Farnsworth Group has been retained to assess the current park facilities as well as design renovations for thelLodge, the lower dormitory, the game room, the gymnasium, and the family cabin (manager’s lodge). Additionally, Farnsworth Group is designing six (6) new 2-bedroom cabins at the park’s upper lake; and is providing upgrades to the park entry road, the wastewater treatment facilities, and the water service lines.

Global Telecom Company SUE and Utility Relocation

Farnsworth group conducted a comprehensive survey and design solution to identify Telecom cables that could conflict with a state highway expansion project.

Farnsworth Group worked with a global telecommunications company to analyze any possible conflict of its cables with a Missouri Department of Transportation (MoDOT) highway expansion project from Interstate-44 to Willard, MO. The project included identification of pothole cables in questionable conflict and reroute design for the company’s facilities and cables in conflict with the MoDOT project. The project stretched 6.3 miles on Highway 160 in Willard.

To gather the required data, a Farnsworth Group engineer and professional land surveyor walked the length of the project using a line locator to determine utility location and check depth of cover.

Farnsworth Group uploaded all field data into Microstation for MoDOT, and then determined areas of possible conflict. After obtaining all necessary permits, Farnsworth Group, by means of a subcontractor, potholed areas in question to know the exact depth of cables crossing underneath the highway. The information retrieved from line locating and potholing was shared with the client and MoDOT as it pertained to them.

With the field and pothole data collected and analyzed, Farnsworth Group drafted construction plans for the reroute of the company’s fiber optic and copper lines which included design for reconnecting service lines to homes and businesses, placing new handholes, placing pedestals, and correcting client records.

State of Missouri Echo Bluff State Park

Echo Bluff State Park marks the State of Missouri’s first new state park in more than 75 years. The State looked to Farnsworth Group and its full-service capabilities to turn this rugged environmental landscape into one of the park system’s crown jewels.

The mission was clear: the park had to be planned, designed, constructed, operational and open to the public in a mere 30 months … a project of this scale that would normally take twice as long.

Farnsworth Group provided a leading role from the Master Planning Stage through Construction Documents and into Construction Administration of the project.

Completed in June 2016, the plans included development of several key areas within the park. Those included:

  1. Development of the roads and bridges for circulation,
  2. Design of the site infrastructure systems including the water, power, sanitary, and stormwater,
  3. A bluff top stone Ozark style pavilion located on top of the limestone cliffs overlooking the Sinking Creek Valley,
  4. Sixty (60) RV camp sites along with walk-in primitive camp sites,
  5. The core area of the park which includes a 20 room rustic lodge, (1) 4 bedroom cabin, (4) 2 bedroom cabins, and (4) stacked duplex cabins. All sighted to take advantage of the views to the Sinking Creek limestone bluffs,
  6. The Day Use Area which includes an amphitheater, pavilions, toilet facilities, and outdoor recreation areas, and
  7. Development of a native planting palette and design for only plants that are currently native to the site.

…the Park has proven to be a premier destination, exceeding expectations for occupancy and garnering high praise for its contemporary spin on the unique Ozark charm and appeal. This success was not possible without the strong, collaborative teamwork between the State of Missouri and the dedicated Farnsworth Group team. Jay NixonGovernor, Missouri

With a very short time line in developing and executing the plan Farnsworth Group had to work closely with various departments within the State of Missouri and the National Park Service. There were also ongoing meetings and coordination with the Governor’s Office throughout the project.

US 69 Bridge Pipeline Triad Relocation

When the Missouri Department of Transportation made the decision to replace a pair of bridges (built in 1933 and 1957) over the Missouri River, a pipeline company had to remove several significant pipelines that were suspended from one of them.

For multiple reasons, our client Magellan Midstream Partners, ultimately opted to pursue re-routing of the pipelines under the Missouri River. Our team provided surveying, engineering, and design for the pipeline relocations, permitting packages, horizontal directional drilling observation and supported the client through all the necessary processes for secure permissions from regulatory authorities.

This project demonstrated that major hurdles of all kinds can be overcome by good engineering, an ability to be flexible, and most importantly, a good faith effort by all parties involved to work together. The project’s technical challenges were daunting, but from a risk assessment perspective, some of the greatest threats to the project were posed by the many permits and approvals upon which the undertaking hinged. We live in an era when layers of intense governmental oversight and scrutiny make large pipeline infrastructure projects more and more difficult to execute. We were able to sit down and find common ground and a path forward, in a timely manner, with the United States Army Corps of Engineers, the Fairfax Drainage District of Kansas, the Riverside-Quindaro Bend Levee District of Missouri, and Union Pacific Railroad.

State of Missouri Echo Bluff State Park Phase I

Echo Bluff experience stamped by interior design intent.

The interior design for this important project is consistent in all the buildings. The 20-room rustic lodge, (1) 4-bedroom cabin, (4) 2-bedroom cabins, and (4) stacked duplex cabins were designed with a modern rustic flair. Durable modular carpet with an organic tree pattern and hand scraped hickory wood floors make up much of the floor finishes.

The Lodge lobby is home to a beautiful staircase, finished in reclaimed wood and iron-trimmed accent light fixtures. Nearby, the grand fireplace is clad in stone, native to the Ozark area, with a large mantel carved from a native tree. Tiles with natural wood and stamped patterns were also used to further carry out the modern rustic design intent.

Echo Bluff State Park New Bridge

Farnsworth Group provided complete engineering services including surveys, floodplain modeling, and preparation of contracts plans, specifications and estimates for this new 456′ bridge at Echo Bluff State Park.

Located on 458 acres in the heart of the unique natural beauty of the Missouri Ozark Mountains, the new Echo Bluff State Park is the complete, quintessential Ozarks destination. Farnsworth Group was selected as the prime A/E firm to carefully transform this beautiful heavily wooded yet rugged land into the State’s signature resort. The first new State Park in 80 years serves as a luxury basecamp for those looking for year-round adventure or simply a relaxing introduction to everything the Ozarks has to offer.

Starting from the conceptual design, the bridge design team completed hydraulic modeling and structural design of the bridge in just four months. The superstructure consists of a four-span bridge with four composite web plate girders supporting a concrete deck. The deck width consists of two vehicular lanes and a multi-use lane. The specialty barriers on the deck are TL-3 crashworthy with a decorative thick stone veneer, stone caps and timber railings. The end bents consist of integral abutments supported by steel piles that were pre-bored and cast in rock sockets to obtain the desired longitudinal flexibility required.

Laumeier Sculpture Park Fine Arts Gallery

Continuing an on-going relationship with the Laumeier Board of Trustees and the St. Louis County Parks Department, Farnsworth Group provided site design services in support of the project architect, Trivers Associates. The board commissioned the design team for a 7,500 SF fine arts gallery building.

The new building is perched at the southern end of the parking lot that was completed during the construction of the new entry road. A new plaza entry was created between the existing estate house and the new gallery to both welcome visitors and funnel them into the park. This plaza can also be converted into an event space with support from the catering kitchen inside the new gallery.

The site was a grading and stormwater management challenge. The building was placed half on the existing drive and half on the existing 3:1 slope that was constructed during the previous project. The area behind the new gallery had to then be re-graded to a 3:1 slope and incorporate walls to mitigate the clearing of a larger portion of the existing tree mass. The grading on the plaza had to be analyzed to maintain ADA cross slopes and connect to both the gallery and the existing estate building without directing the runoff to the end of the plaza. Farnsworth Group was careful during this process not to create a “muddy mess” where the plaza meets the park lawn.

Other stormwater challenges included stormwater quality and flood protection storage. The previous projects had already added additional enough run off that any additional work in the park would require flood protection storage. After multiple iteration using bioretention area for stormwater quality and a dry basin for flood protection storage, the design team suggested removing the existing asphalt parking stalls and installing pervious pavement. The pervious pavement would reduce the run off enough so that flood protection storage would no longer be required and would be the stormwater quality BMP. In addition, the costs for the two scenarios were approximately equal but the pervious pavement scenario was a much cleaner look for the park.

City of Webster Groves North Rock Hill Road Improvements

North Rock Hill Road is an urban collector and one of the major gateways into the City of Webster Groves connecting the City to other major roadways in the greater St. Louis area. This project consisted of reconstructing approximately 2,000 LF of roadway.

The existing street consisted of two, 15-feet wide driving lanes with a rolled curb and narrow asphalt shoulders on both sides. The additional lane width and asphalt shoulders were used as unsightly makeshift parking lanes on both sides. This project improved the road to an 11-feet wide drive lane with an 8-feet wide parking lane on both sides. The additional width resulted in the need to also reconstruct the existing sidewalks and driveways. Intersections with existing side roads were designed to work with the new road profiles while sidewalks and handicapped ramps were constructed to meet current ADA requirements.

Coordination between the utilities was necessary to accomplish various relocations and adjustments. This work included relocating power poles containing both overhead electric and telephone behind the new curb and adjusting water, gas and sewer facilities to the new grades.

The Metropolitan St. Louis Sewer District required conformance to their Stormwater Quality Requirements to treat runoff prior to discharging into the storm sewers. To accomplish this Pervious Interlocking Concrete Pavers (PICP) were designed for use in the parking lanes. On-site percolations tests were completed to allow for a higher ratio of impervious to pervious area and a 16-inch aggregate drainage base in lieu of the standard 12-inch base to meet the requirements. The pavers were chosen by the City to provide a contrast from the normal drive lane. This also allows for the pavement to be removed and replaced should that ever be necessary for maintenance.

City of Webster Groves Murdoch Avenue Bridge Reconstruction

Farnsworth Group was chosen to provide engineering services for a new replacement bridge.

Originally constructed in 1930, the existing concrete bridge over the BNSF Railway tracks had deteriorated to become structurally insufficient as well as deficient in vertical clearance over the tracks. As a vital connector between the City of Webster Groves and Interstate Highway 44, the City took action to secure federal matching funds through the Bridge Replacement and Rehabilitation (BRM) program administered by the Missouri Department of Transportation (MoDOT).

The project location for the new bridge was tightly confined to the south by the I-44 westbound on-ramp and to the north by Frisco Avenue and a large building. Compounding these horizontal constraints was the requirement by BNSF and MoDOT to increase the clearance to at least 22’-0” from the existing 20’-10”. Together these constraints challenged the design team to find a unique solution that was not only cost effective, but also minimized the shutdown time.

Through a series of meetings with the City of Webster Groves, MoDOT and BNSF, the design team gained consensus for the use of precast concrete, flat-top, 3-sided bridge sections. These precast sections allowed for the thinnest bridge deck to maximize vertical clearance. Considerable time was spent developing the appropriate crest and sag vertical curves road profile over the bridge while at the same time minimizing the impact to surrounding roads. Working with BNSF, design variances were granted for both horizontal and vertical clearance from their rails to help make this project possible.
