ES&S served as the prime consultant to the City of Sedalia on Phase IIIa of the Downtown Streetscape initiative.  This was a continuation of infrastructure reconstruction and aesthetic upgrades along Ohio Street in the historic downtown district.  Services included civil design, and design / construction support services for slightly more than one city block immediately north of Broadway Blvd./US Route 50.  Infrastructure improvements included total street reconstruction with curb and gutter, new sidewalk, storm drainage structure replacement and piping upgrades, coordination of a water main replacement and other utility relocations.

Coordiation was required with MoDOT relative to the improvements made in their ROW adjacent to the signalized intersection of Ohio Street and 50 Highway.  This included sidewalk ramps and clearances that comply with requirements of the Americans with Disabilities Act (ADA).  Aesthetic features included the addition of brick pavers at crosswalks, as edge treatments along sidewalks, and historic lighting fixtures along the revitalized corridor.  The most striking feature of the project is a new “downtown gateway” feature that was designed under a separate contract by the Kansas City-based urban planning/design firm of Ochsner Hare & Hare (OHH).  OHH was part of the ES&S design team for this streetscape project to assist in the close coordination required between the City, MoDOT and the adjacent church, whose building abuts the road’s ROW limits.

Bid and construction phase services included preparation of design and contracting documents, bid-assistance, opinions of probable construction cost, and coordination of contractor inquiries during construction.  Field services included onsite resident observation and materials quality assurance throughout the construction phase of the project.  ES&S provided these same services on Phase II of the Downtown Streetscape initiative, and provided construction-phase support and come civil engineering design revisions on Phase I.

ES&S provided complete site planning and design services for the development of a medical park on a greenfield site at the intersection of Providence Road (MO Route 163) and Southampton Drive.  The site plan for this 24-acre site called for site layout of an 85,000-sf medical office building and 425-stall parking lot, plus provision for a future Phase II building.  Design services included boundary survey, subsurface investigation, site planning, hydrologic evaluation and storm drainage design, and erosion and sediment control.  The project incorporated low-impact development design features, such as maximizing overland flow by reducing impervious surface area and enclosed storm drainage, and including several bioretention and detention basins as stormwater BMPs.  The large, site retention basin created also serves as an aesthetic water feature for the medical campus.  The design included bioretention and a native vegetative buffer around the basin to both reduce and cleanse onsite stormwater runoff via increased infiltration and evapotranspiration.  The basin also serves as a source for irrigation water, with a well to supplement water level during dry periods.  ES&S provided these services as a subconsultant to prime architectural consultant, SOA.  Additional services facilitated by ES&S under subcontract included landscape architecture (Loomis & Associates) and a traffic engineering study (Crawford, Bunte & Brammeier).

Transportation design included the addition of a dual left turn lane from westbound Southampton Drive to southbound Providence Road, which is dual-designated MO Route 163, requiring coordination with MoDOT.  Multi-modal features include an onsite fitness trail with connections created to the City of Columbia’s Providence Pedway and a nearby transit stop.

ES&S provided full site design for a new, two-story headquarters building for the City of Sedalia Police Department.  The 18,700-sf facility provides increased evidence storage space, a training room, an exercise room, men’s and women’s locker rooms, K9 kennels, interview rooms, and unfinished office space that will allow room for future department expansion as the City population grows.

Site planning and design services included topographic & boundary survey, easement displays, geotechnical investigation on part of the site where previous structures had existed, grading plan, enclosed storm drainage design, concrete drive and parking area, and utility connections.  Construction-support services included staking, concrete strength and soil compaction testing, and observation of foundation construction, steel reinforcement, and steel weld and bolt inspection.

ES&S provided services both as a prime consultant to the City of Sedalia, as well as a subconsultant to the prime design firm, GHN|Architects-Engineers.

The project consisted of site grading, drainage and utility relocation design for this new destination feature on the flagship campus of the University of Missouri in Columbia. Located on the north end of the Mel Carnahan Quadrangle, Traditions Plaza is an amphitheater, memorial, and “…a variety of features honoring MU’s history and heritage. MU traditions along with notable quotations are etched in the bricks and tiles that create the stage and pillars making the plaza one of the most cherished and hallowed locations on central campus.” *

Services were provided as a subconsultant to prime designer, DTLS Landscape Studio.

Angel Lane is a low-volume, two-lane, asphalt roadway that has served as the “back entrance” to Columbia Regional Airport for many years.  Detours from roadway construction on US Route 63, which runs west of the airport property, resulted in increased traffic using Angel Lane to gain access to the airport, and for heavily loaded vehicles associated with the construction activity.  The increased volume over several years contributed to poor pavement conditions.  ES&S was engaged by the City of Ashland to perform a subsurface investigation and make recommendations for pavement rehabilitation or replacement.  Results of the study showed substantial failure of the subgrade material along this 1.25-mile paved road.  For this reason, a mere resurfacing was not recommended, especially since the City owns property along the corridor, with hopes of developing an industrial park in the future.

Funding challenges for a major reconstruction of the pavement caused a search for innovative alternatives.  The City worked in partnership with Boone County to fund this project.  The County had recently reconstructed a roadway in north Columbia using Full Depth Reclamation (FDR).  The FDR construction process mills and recycles the existing pavement and sub-base materials of a roadway.  With the addition of cement, the recycled material is mixed, shaped and compacted to create a more stable material that can then be used as a base for a roadway surface course.  FDR can be a cost-effective means of providing a higher quality pavement for lower-volume roadways than traditional reconstruction or mere resurfacing.

For the Angel Lane project, the use of FDR for the full length of the roadway resulted in a cost-savings of over 35-percent compared to an option with full-depth PCC pavement for approximately one-third of the length.  ES&S facilitated a “Lunch & Learn” for public works officials in the region to observe the FDR process.

ES&S provided consulting and design services for the closure of two lagoons serving a homeowners’ association.  An Engineering Report was developed outlining the closure plans as well as the conceptual design of relief sewers to connect to the BCRSD system.  Final design services included over 3000-LF of 8-inch PVC gravity sewer to relieve the two existing lagoons, two bores under I-70, and coordination of a crossing under a high-pressure petroleum pipeline.  Application to the State Revolving Loan Fund were included as part of the submittal to the client.

As part of the planning and design of a new surface parking lot, ES&S provided complete design services for an underground storm water detention and water quality facility serving the central campus.  This project was a recommendation from the Campus-Wide Stormwater Master Plan, prepared by ES&S in February 2011.  The new facility was designed to account for the cumulative increase in runoff associated with full build out of the College’s facility master plan.  The project included use of ADS’s StormTech® subsurface storm water management system storage, including the use of StormTech Isolator™ Row units to provide for water quality improvement to reach the Level of Service (LS) requirements of the City of Columbia’s revised (2008) storm water management ordinance.  The WQ facility sits under the surface parking lot at the corner of Eighth & Wilkes Streets (right)

ES&S provided full site design services for the new 60,000-sf, four-story, academic and residence hall for Columbia College. The first floor of the facility houses the Robert W. Plaster School of Business, consisting of offices, six classrooms and a larger event center.  The second, third and fourth floors will contain a 150-bed student dormitory.

Design services included site layout and full civil engineering and design-support services for the new building.  Specific design features included property surveys, site layout of building and parking, grading, drainage, erosion and sediment control, and utility connections.  The subsurface investigation included extensive mapping and coordination due to the relocation of existing utilities for the building site, which is in the heart of the college’s main campus.  ES&S also provided calculations necessary permitting documentation regarding the impacts of the new construction relative to the campus’ regional storm water detention and water quality facilities, which were constructed as part of a campus-wide storm water master plan completed by the firm in 2011.  There was also a feasibility study completed to determine the most efficient connection to the City’s sanitary sewer system, followed by design of a new pump station and force main.

Construction-support services included construction surveys and layout, observation of foundation construction and reinforcing steel, and quality assurance testing for construction materials, steel connections, and fireproofing materials.

ES&S provided site layout planning and design services as part of an initiative to develop the North Quadrangle area in the heart of the College’s main campus.  The project includes significant new additions to the grounds, including the Whitcraft-Schiffman Memorial AmphitheaterAlumni Fountain, addition of Christian College* Garden, an outdoor dining pavilion, and relocation of the campus security office to this prominent gathering area.  Since the onset of the initiative, the quad has become a centrally-located gathering space for students to relax, study, and socialize.

Services included participation in site layout iterations, topographic and boundary surveys, subsurface investigations, extensive utility mapping and relocation design, grading plan, drainage, erosion and sediment control, sidewalk and parking lot upgrades, and new hardscape features including permeable pavement to improve storm runoff water quality.  ES&S worked as subconsultant to prime architectural consultant, SOA.
