Jones Edmunds supported Delaware North Companies with design and construction professional services for widening Space Commerce Way, a new signalized intersection, and a new multi-lane access roadway north from the new intersection into the Visitor Complex south Parking Lot 7, where a new parking plaza was constructed to handle visitor parking. The traffic signal design includes a specialized hinged mast arm to allow for rotation of the mast arms to provide clearance for large payloads transported from commercial aerospace facilities along Space Commerce Way. Jones Edmunds played a key role in compiling requirements for hardware transport and implementing solutions.
The project included a NEPA-compliant Environmental Assessment and Traffic Study. The design included signalization, roadway construction, parking area improvements, stormwater management systems, wetland mitigation, and site lighting. Jones Edmunds facilitated FPL’s involvement in providing power supply, incorporated their design standards into the project, and coordinated easement development.
Jones Edmunds’ experience, understanding, and prioritization of NASA’s institutional processes and key stakeholders helped ensure compliance and proper approval from authorities involved. Jones Edmunds spearheaded stakeholder involvement for collaboration, problem-solving, and ongoing status updates. Stakeholders included NASA Environmental, Engineering, Master Planning, Fire, Surveying, Traffic, Blue Origin, FPL, Space Florida, St. Johns River Water Management District, and US Army Corps of Engineers. Jones Edmunds provided construction administration, engineering, and inspection support to Delaware North through construction completion. This included compliance with permit agency requirements, certifications, and record documents. Jones Edmunds is now providing ongoing wetland monitoring as required by the USACE permit.
Jones Edmunds provided preliminary engineering, final design, contract document preparation, and bidding- and construction-phase services for the Braden River Utilities (BRU) Reclaimed Water Interconnect Project. The $13-million project brings reclaimed water to Lakewood Ranch, a residential development, from the City of Bradenton and solves the irrigation issues that the development has had since its inception 20 years ago. It also reduces the City’s discharge to the Manatee River.
The project consisted of reclaimed water transmission and distribution lines, pumping facilities, and a storage facility to interconnect with the City of Bradenton reclaimed water system and expand BRU’s irrigation storage transmission system. Jones Edmunds prepared the plans, specifications, and permit applications in five separate bidding packages, including hydraulic modeling of the reclaimed water transmission system.
The total length of the project consisted of approximately 49,000 feet of 20-inch transmission main and 4,900 feet of 16-inch and 4,600 feet of 12-inch distribution mains. The project also included a new pump station capable of delivering a minimum of 1,400 gpm (2 MGD) and a maximum of 4,200 gpm (6 MGD) at the City’s 2-million-gallon ground storage tank at the River Run Golf Course. Approximately 5,000 feet of existing 16-inch ductile iron and PVC pipe crossing the Braden River were reused. Due to the heavily congested route, the pipeline required many horizontal directional drills, including a 2,400-foot drill under I-75.
As a multi-jurisdictional, private-public partnership, this project was co-funded by BRU and the Southwest Florida Water Management District (SWFWMD), and the City of Bradenton provided assets, including the River Run Pump Station and a 4,200-foot section of existing 16-inch diameter transmission pipe.
In 2014, this project was named the American Society of Civil Engineers (ASCE) SunCoast Branch Project of the Year.
Walton County’s existing transfer station needed to be replaced because it was not ideally designed for this purpose and was nearing the end of its useful life. In addition, the existing facility was not well located on the County’s solid waste management site with respect to future solid waste management needs of the County.
Jones Edmunds worked closely with County staff to develop a Concept Plan for a new solid waste transfer station in concert with the County’s longer term goals and objectives for solid waste management. To provide more efficient management of solid waste by the County, Jones Edmunds developed recommendations for a more effective transfer station design and optimum location for the facility on the County’s solid waste management site. We prepared a detailed report that assessed the sizing needs for the new facility, evaluated three site location options and associated costs, and provided schematic drawings of the proposed site plans and the proposed building plan and elevations. Based on regulatory requirements, good engineering design, and input from County staff, Jones Edmunds incorporated the proposed design elements for the facilities including vehicle access and routing, operational needs such as breakroom and bathroom facilities, leachate collection and management, truck scale requirements, provision for electric power, access roadway and inbound scale facility, site paving and grading, building design to accommodate future expansion of the facility, stormwater management, provision for fire protection, extra trailer parking, and communication capabilities to other site facilities. The Concept Plan was presented to the County and draft format for review and comment. Upon discussion of County comments, the Concept Plan was finalized and approved by the County.
Following completion of the site Concept Plan, Jones Edmunds developed preliminary design documents for the civil site work and building architectural, mechanical, electrical, plumbing, and structural design for the Solid Waste Transfer Station Facility. The structural, mechanical, electrical, and plumbing design elements were prepared by subconsultant McVeigh and Mangum, and the architectural design was prepared by subconsultant WMB-ROI. Jones Edmunds also coordinated the preparation of site survey and geotechnical investigations through subconsultants for the project. Jones Edmunds worked with local City utilities providers to assess and provide for water and sewer service requirements for the facility. The work products consisted of construction drawings and technical specifications to the level necessary to prepare FDEP permit application packages consisting of Solid Waste Processing Facility Permit Application and Environmental Resources Permit Application for submittal to FDEP. Jones Edmunds coordinated reapplication meetings for both permits and coordinated with County staff. Both FDEP permits were received with minimal comments from the reviewers. We also prepared the FDEP water and sewer service connection permits, coordinating these applications and final design details with the City.
Upon confirmation of approved permit applications, Jones Edmunds developed Construction Bid Documents that include complete design drawings and specifications for Bidding and Construction. We worked with County procurement staff to develop the final bid documents for use in the bidding process.
Jones Edmunds and team are providing pre-design, design services, final design, permitting, and bidding phase services for improvements to the Marshall Street Water Reclamation Facility (WRF). This work includes replacement of the IPS and the headworks structure and associated odor control systems, an influent flow equalization (EQ) tank , electrical, instrumentation and control improvements, and collaborating with Duke Energy to upgrade the electrical / transformer loop between the new IPS, Reclaimed Water High Service Pump Station, and Laboratory transformers. The design will incorporate constructability in a phased approach that minimizes impacts to the operations of the WRF during construction and startup to maintain compliance with the WRF’s FDEP Operating Permit.
The Crawlerway at the Kennedy Space Center is a 130-foot wide and over 4.5-mile long pathway between the Vehicle Assembly Building (VAB) and the two launch pads at Launch Complex 39. Natural soil and 3 feet of hydraulically dredged soil are below a 5-foot layer of compacted limerock, which lies beneath a 4 to 8 inch surface of Alabama river rocks, which were chosen for many properties, including hardness, roundness, sphericity and resistance to LA Abrasion. The Crawlerway was constructed in the early 1960’s and supported heavy space rockets being rolled to the launch pads throughout the Apollo and Shuttle Programs. Since the end of the Shuttle Program, heavy loads have not been traversing along the Crawlerway for many years and the Crawlerway soil foundation strength has waned and needs refurbishing and strengthening to support NASA’s next space program. By 2013, a project to repair and upgrade the Crawlerway was undertaken. It was the first time the foundation had been repaired since it was constructed. The limerock layer was increased by 2 inches, and the degraded river rock was removed and replaced with new river rock.
The Crawlerway was originally designed to support the weight of the Saturn V rocket and its payload, plus the Launch Umbilical Tower and Mobile Launch Platform (MLP), atop a Crawler Transporter (CT) during the Apollo Program. The total load to the ground was over 17 million pounds. The Crawlerway was also used from 1981 to 2011 to transport the Space Shuttles, also atop the MLP and CT, with a total load of 18 million pounds.
Jones Edmunds provided a study to evaluate the Crawlerway foundation for the transition from the Shuttle Program to NASA’s new heavy-lift vehicle, SLS. The Shuttle weighed 18 million pounds, and NASA’s new heavy-lift vehicle is expected to weigh over 26 million pounds.
The goals of this project included determining if the foundation could handle the increased load and performing a full-scale load test using a CT shoe to find the most suitable surface to use with the new heavy-lift vehicle.
We coordinated with several NASA organizations and their subconsultants to mobilize the load test apparatus, including Ames Research Center, Florida Department of Transportation, USACE ERDC, United Space Alliance, and EG&G. The load test required 500,000 pounds of weight vertically loaded onto the existing CT track shoe. A 250-ton “water bottle”, which NASA uses at the VAB to certify cranes, was used as ballast for the horizontal load. The load test included evaluating various gravel materials and resilient mats, while pressure cells were used to better understand distribution of the load under the CT shoe.
This project was awarded the 2011 Florida Section Project of the Year by the American Society of Civil Engineers.
Jones Edmunds was selected to support the Florida Keys Aqueduct Authority (FKAA) for a multi-phase Cityworks implementation. The first phase was a utility-wide review of business processes related to GIS and work and asset management, which included discovery meetings with 10 different departments including IT, Finance, Customer Service, and their entire operations group including lift stations, wastewater collection, water distribution, fleet, and water production. FKAA has many disparate systems including their finance and customer service software (Cogsdale), Esri GIS, CCTV, and SCADA. One of the primary outcomes of the review was the need for a Cityworks integration with their Cogsdale to reconcile fixed assets, customers and meter related work orders. Phase 2, a Cityworks implementation for their linear water system, fleet, and customer service, included the Cogsdale integration. Phase 2 also included implementation of an Enterprise GIS that included GIS database re-design, deployment, and configuration to cloud servers on Azure to ensure high availability, including ArcGIS Server and Web Adaptor. Phase 3 includes an implementation of Cityworks for their wastewater and water vertical assets, technical services, engineering, and backflow prevention with integrations with SCADA and Neptune.
Jones Edmunds conducted gopher tortoise survey, permitting, and relocation services for the South Florida Water Management District (SFWMD) Lakeside Ranch Stormwater Treatment Area project that comprises over 1,200 acres. Jones Edmunds also completed extensive vegetation and tortoise surveys for the SFWMD Hickory Hammock and Ft. Basinger recipient sites. We prepared and submitted two separate gopher tortoise relocation (Conservation) and a Long-Term Recipient Site permit application to the FWC and obtained permits. The Ft. Basinger site is SFWMD’s first gopher tortoise recipient site. Burrowing owls, bald eagles, and Sherman’s fox squirrels were also documented on-site by Jones Edmunds scientists. Jones Edmunds conducted several pre-construction 100% tortoise surveys of the site, assisted with and supervised the backhoe excavation of over 300 burrows, and transported and released over 150 tortoises to the SFWMD Hickory Hammock or the Brahma Island Recipient Site. We generated a Final Report which summarized the surveys, permitting, and relocation activities at this site.
The new seven-story, 200,000-SF Headquarters is a gateway building and Central Campus hub for NASA’s employees at the Kennedy Space Center. This project was led by HuntonBrady as the prime consultant to NASA, with Jones Edmunds as subconsultant throughout all design and construction phases. Jones Edmunds provided site stormwater management system design and permitting, including modifications to the KSC Region 1 Stormwater Permit, utility infrastructure design including water, sanitary sewer, and stormwater utilities and paving and grading of new roadway connections and parking facilities. We provided NASA with follow-on construction administration services for Phase 1 of the new Headquarters building, Kennedy Data Center facility, and associated off-site infrastructure improvements. Jones Edmunds is also providing design services for Phase 2 of the project and has designed a new signalized intersection currently in construction at the main entrance to the Headquarters building off of NASA Parkway.
This project is part of a planned campus theme designed to replace the current Headquarters building and several other support buildings within the Industrial Area. The campus theme was developed during a Master Planning effort in 2010 led by Jones Edmunds with HuntonBrady as the Chief Architect and Planner supporting NASA. The Master Planning effort developed multiple new campus scenarios, each involving transportation, infrastructure, and facilities planning elements, ultimately arriving at the selection of the concept used in the current design and construction phases.
Paynes Prairie Preserve State Park in Alachua County, Florida, became Florida’s first State Preserve in 1971 and is widely known as a world-class wetland. The Prairie has been designated an Outstanding Florida Water as well as a Florida Natural and Historical Landmark. Stormwater runoff and pollution from the City of Gainesville (Paynes Prairie’s closest neighbor) flowing downhill in Sweetwater Branch onto the Prairie Basin had a marked effect on the water quality, water quantity, and aquatic plant communities of the Prairie’s wetlands and lakes. Alachua Sink, a natural lake within Paynes Prairie, was identified as an impaired water body and FDEP established a regulatory TMDL that required nitrogen discharging to this lake to be reduced from all sources. The Sweetwater Branch/Paynes Prairie Sheetflow Restoration Project presented a unique opportunity to rectify these problems while providing additional wildlife habitat, wildlife viewing, and public recreation opportunities.
Jones Edmunds was selected to provide design, permitting, and construction administration; wetland assessments and mapping; wetland jurisdictional line determination; mitigation plan and design; site evaluation; Phase I, II, and III EA; environmental sample collection and analyses; and contamination assessment. Two primary goals were addressed by the Sheetflow Restoration Project. Goal Number 1 was to satisfy the nitrogen-load reductions from the Main Street Water Reclamation Facility and urban stormwater to Sweetwater Branch as part of the TMDL requirements for the Alachua Sink. Goal Number 2 was to restore the rehydration mechanisms of Paynes Prairie to their natural condition.
The design entailed developing detailed site grading plans for a project footprint of over 250 acres and more than 1 million cubic yards of combined excavation and embankment. Jones Edmunds achieved a balanced site; earthwork cut and fill needs were equaled, so no fill material had to be imported or exported. Jones Edmunds also coordinated the architectural designs and electrical and mechanical system designs associated with the three on-site buildings, and the project included low-impact development stormwater controls. Extensive hydrologic and hydraulic modeling was performed to develop tools for the design and operation of stormwater conveyance, wetland treatment system, and sheetflow restoration.
Today, the public has direct access to enjoy the restored Prairie’s natural beauty and wildlife by visiting Sweetwater Wetlands Park. Shaped like the head of an alligator, the park consists of more than 125 acres of wetlands and ponds and is now a thriving habitat filled with plants and animals, including birds, butterflies, alligators, wild Florida cracker horses, and buffalo. There are 3.5 miles of walking trails, boardwalks, and elevated berms integrated throughout the stormwater treatment mechanisms. Other public amenities include a Visitors Center, a security residence and classroom facilities (all with associated utility services), educational signs and guided tours, and numerous shade pavilions and viewing towers.
Jones Edmunds assisted St. Johns County in further developing its pavement management program (PMP). The County’s goals for this PMP were to build on the existing County pavement management components and to develop a program to improve the ability of County staff to routinely assess, prioritize, and track pavement management activities. The PMP will facilitate efficient allocation of County resources to maintain the County’s roadways and will be implemented and maintained by County staff. We developed an overall framework for the PMP; developed standard operating procedures (SOP) for typical analysis and reporting tasks using the County’s pavement management system; modeled maintenance and rehabilitation scenarios within MicroPAVER to develop a work plan for the annual County maintenance and rehabilitation activities; and coordinated and led workshops at the County to present the modeling results, work plan, and PMP.
Jones Edmunds also provided Construction Administration services for the County’s Pavement Management Program (PMP). For the PMP, the County uses its continuing services Contractors to perform drainage and roadway improvements throughout the County. Construction Administration duties included all phases of construction from planning, monitoring construction and schedule, cost estimating, and contractor pay requests.
The Southwest Regional Water Reclamation Facility (SWRWRF) was an existing wastewater treatment facility that Citrus County owned and operated. It was located approximately 3 miles east of the Chassahowitzka River, which is an Outstanding Florida Water.
The Chassahowitzka River flows to the Gulf of Mexico and is formed from pristine waters contributed by more than 12 springs. Jones Edmunds completed the planning, permitting, and design phase of an advanced wastewater treatment plant meeting a 5-5-3 effluent quality to replace the existing WRF. Construction began in 2017 and was completed in 2019. A new 1.5-MGD AADF 4-stage BNR oxidation ditch system replaced the current facility. The new system has secondary clarifiers, disc filters, and chlorine disinfection capabilities. Reclaimed water disposes to rapid infiltration basins on the plant site and eventually to the County’s public access reuse system.
Our design addressed the following goals and objectives identified to upgrade the Southwest Regional WRF:
Jones Edmunds also prepared a Wastewater Facilities Plan in support of an SRF Construction Loan application. We provided additional support during the application process.Read more about the Construction Administration services for this project.
Gainesville Regional Utilities (GRU) selected Jones Edmunds to conduct a needs/workflow assessment and develop an implementation plan. This implementation plan served as the roadmap to the roll-out of Azteca Cityworks and included database design, data migration, workflow re-engineering, software implementation, and training.
In addition to the existing GIS and work-order data, the GIS-centric database design had numerous considerations to be evaluated. Several independent legacy Oracle databases had to be reconciled and migrated into a common relational database. Subsequent to the enterprise deployment of Cityworks, GRU has gained considerable benefits, including but not limited to a significant reduction of the time associated with entry, analysis, and report generation of service requests and work orders. GRU now plans to make further use of the benefits gained by the Cityworks implementation. Jones Edmunds worked with GRU to update the initial needs assessment and implementation plan. GRU has been improving system monitoring, planning, and proactive maintenance by further using Cityworks, saving the utility and its customers money.
Jones Edmunds helped implement an ArcFM 8.2/CityWorks 4.0-based solution for updating and maintaining the GRU Water and Wastewater Facilities Mapping and Work-Order Management Systems, converting existing coverage and hardcopy data to a GeoDatabase. The project used a single geodatabase to support facilities management software (ArcFM 8.2), work-order management software (Azteca Systems’ CityWorks 4.0), and future applications such as hydraulic modeling.
ArcGIS and ArcFM serve as the principal mapping and data management tools for GRU’s water and wastewater infrastructure. Existing ArcInfo coverage and hardcopy data were converted to a geodatabase that is administered by ArcSDE within Oracle. The GDB is available to users of ArcFM and Cityworks to support facility-mapping, work-order, and facility-maintenance functions. We developed custom procedures to enable GRU staff to incorporate as-built data into the GeoDatabase—a process currently contracted out.
Jones Edmunds is supporting the St. Johns River Water Management District (SJRWMD) with preliminary design, final design, and permitting of flow restoration improvements associated with Crane Creek and M-1 Canal Flow Restoration Project. The project is based on the recommendations of the 2016 Indian River Lagoon (IRL) Stormwater Capture and Treatment Project Development and Feasibility Study, where Jones Edmunds was the lead consultant to the District and IRL Council. The project is intended to achieve water quality goals contributing to ecological restoration in the IRL while providing water supply benefits to the St. Johns River.
The project involves design and permitting of an operable control structure, base flow pumping station, conveyance systems including a crossing of I-95, and a stormwater treatment area (STA) that ultimately discharges to the St. Johns River. The project includes stakeholder and regulator meetings, field investigations, hydraulic and hydrologic (H&H) modeling, property acquisition support, funding support, preliminary engineering, final design, construction cost opinions, and related support to the District for readying the project for procurement and construction contracting.
Jones Edmunds completed the construction contract administration and full-time resident observations for two construction projects (designed by others) that were bid together as one construction package for Alachua County Public Works. The projects were funded through FDOT and FEMA HMGP and were needed repairs due to damages from Hurricane Irma. The projects were:
In addition to providing the County with construction contract administration and resident observation, we also provided Davis-Bacon compliance services as are required in any funding agreement that uses federal monies. The Davis-Bacon compliance services included on-site wage interviews, compiling and verifying for accuracy the contractors wage statements submitted weekly, keeping an on-site project file for review by funding agencies, and leading funding agency review site visits.
Resident Observation services provided by our subsidiary firm JEAces as a subconsultant.
In this project that attracted national and international attention, Jones Edmunds provided project support for a broad range of resource areas including land use, water resources (wetlands, floodplains, surface waters, groundwater, and Wild and Scenic Rivers/Special Class water bodies), threatened and endangered species, infrastructure and utilities impacts, and transportation (highway access, roads, and railroads) impacts to natural resources. We also assisted with the required extensive public involvement and were involved with extensive agency coordination for the many possible alternatives to the proposed action.
Jones Edmunds coordinated with, prepared, and obtained approval from the USFWS Merritt Island Wildlife Refuge of a listed species survey plan for the launch complex and two proposed off-site support facilities in Volusia County. We subsequently completed USFWS/FWC-compliant Florida scrub-jay, eastern indigo snake, gopher tortoise, and four seasonal migratory bird surveys at the proposed at each location. We also set up four drift fence arrays to survey to investigate amphibian species such as the gopher frog and herpetofauna species at the Shiloh Launch Complex site. We completed jurisdictional wetland delineations for the USACE at the Shiloh Launch Complex, two off-site support facilities, and a notional Pad 49 at KSC and obtained jurisdictional determination permits. We provided information necessary to support Section 404(b) review and development of the USACE Least Environmentally Damaging Practicable Alternative and prepared a final report that was submitted to Space Florida.
For the last 60 years, the Keller Water Treatment plant has served Pinellas County. It was beginning to show its age, and the fear was a hurricane, or blackout or brownout could shut it down, which would deprive 900,000 Floridians of potable water. Jones Edmunds was selected to help with the transition to a newer system. Jones Edmunds provided planning, design, permitting, and construction phase services to construct a new high-service/transfer pumping station capable of distributing 55 million gallons of water a day and upgrade the chemical feed facility. The project included adding a new hydraulic surge-control station and emergency water supply bypass station, as well as a new control building rated for a Category V hurricane. The project also assisted in the County’s overall plan to mitigate the annual flushing water required to maintain water quality. Electrical capital costs were reduced with medium voltage pumps, switchgear, and an emergency generator. Overall, the project saved the county $1 million.
Jones Edmunds provided engineering services to design and permit the first cell – approximately 40 acres – of a new 220-acre Class I landfill. Jones Edmunds performed a preliminary engineering study to offer cost-saving options that included evaluating releasing conservation easements, various liner system and leachate collection system configurations, and cell size and location options. We performed stormwater modeling and wetland mitigation analysis for the 220-acre final buildout and the existing slurry wall landfill to obtain an ERP. To maximize landfill capacity and reduce the amount of imported fill required, the new cell’s bottom liner will be constructed up to 10 feet below the groundwater table. We developed a dewatering plan and on-site groundwater recharge specifications and operations that will minimize impact to the adjacent Slurry Wall Landfill. Jones Edmunds also performed a value-engineering study of the design to identify areas that could reduce the capital cost. We helped the County obtain a permit modification based on the value-engineering changes and provided bid-level documents. The $20-million expansion is the first lined landfill for the County.
Tucked into the southwest coast of Florida, the beauty of Charlotte Harbor has drawn countless people to its shores. A regional effort is underway to improve and protect this crucial natural resource which impacts ecosystems, fisheries, marine and wildlife habitats, beaches, coastal wetlands, our tourism industry, home values, and overall quality of life. As a part of this effort, Charlotte County developed the Blue Water Strategy to ensure and sustain the quality of natural water resources to protect and provide a safe water supply, a recreational haven and an environmental resource. The Blue Water Strategy consists of four key components: wastewater, reclaimed water, stormwater, and drinking water.
As a part of the Blue Water Strategy, the County enlisted Jones Edmunds to prepare the county-wide sewer master plan. Studies found that aging septic tanks drain into nearby waterways, contributing to water quality issues that can impact this resource. To improve the harbor’s water quality, Charlotte County plans to replace about 25,000 septic tanks with an affordable, reliable, and efficient wastewater collection and treatment system. We prioritized neighborhoods to convert the oldest septic systems near waterways first and developed a plan to help connect 14 neighborhoods to centralized wastewater system during the first 5-year phase to lower nitrogen loads. We were also tasked with identifying wastewater transmission and treatment facility improvements or expansions that would be needed to provide reliable service to the County’s growing population. The Geographic Information System-based models we developed provided data and cost-estimating tools for prioritizing the work.
The Harbor Palms residential neighborhood consists of 473 homes, and the infrastructure and utilities are estimated to be approximately 40 years old. The PVC water mains were privately constructed and maintained, but later the City took over maintenance responsibilities. The materials used to construct the utilities do not meet City utility design standards; the mains are inadequate in both size and material and are failing.
Many roadways and sidewalks are reaching the end of their useful lives, and some sections are exhibiting major distress from subsurface water damage. Also, the City wishes to evaluate extending reclaimed water services within the development and provide individual service connections to each home.
Jones Edmunds designed new water and reclaimed distribution piping with new individual service connections to replace the existing substandard piping. This included analyzing pressures and flows, upsizing mains to improve flows, upgrading water services within the rights-of-way, and analyzing and repositioning fire hydrants. The sanitary sewer clay pipes and storm sewer pipes were videoed and assessed to identify point repair locations. Sidewalks and roadways were assessed with the goal of abandoning the rear easement pipe and redirecting stormwater to the roadways.
The work included roadway plan production for the multiple roadway rehabilitation techniques. This included pavement evaluations, costing of rehabilitation alternatives, investigating high groundwater concerns, pavement design, and coordination with the client and their operations and maintenance staff. Sidewalks were rehabilitated and/or replaced and brought to ADA standards.
Due to increasing growth, the City expects that its raw water production will reach capacity in the near future. As a result, the City entered into an agreement with the City of Dade City to purchase water to meet the City’s future potable water needs. This water will be delivered to the City through a water main and booster pump station installed on the west side of US 301 from Phelps Road to US 98. The elements of this project include the following:
Jones Edmunds provided Construction Administration Services during the entire project which entailed coordination between both Municipalities and the FDOT, Review of Submittals, Part-time Resident Observation, Witnessing of Tests, Conducting Meetings, Administering Contract Change Orders, Training of City Operating Personnel, production of Final Record Drawings and Certification to the Florida Department of Environmental Protection.
Gainesville Regional Utilities (GRU) has historically invested significant resources to evaluate and reduce I&I sources but recognized the need for a more programmatic approach for prioritizing rehabilitation and replacement efforts. GRU provides wastewater service to approximately 200,000 people. The GRU wastewater collection system includes over 1,100 miles of piping, 15,500 manholes, 170 lift stations, and 65,000 customer connections.
Recognizing that GRU has excellent technical staff with great institutional knowledge of their system and many lessons learned about what works best for their system and staff, we developed the I&I Reduction Program in a highly collaborative process with them. A decision we made collectively at the beginning of the project was to use an early-out area to go through the tasks that GRU would perform on an annual basis after our team had developed the Program as a way to make refinements and fill data gaps prior to going into a full-scale production. By completing the field investigations, including flow monitoring, smoke testing, manhole inspections, and night-time flow isolation in the early-out area, the Program team was able to determine processes that can best be used moving forward in other parts of the system, with lessons learned being applied.
One of the next major elements of the project was converting lift stations runtimes to flow hydrographs for the most recent two years of data for approximately 170 lift stations. We then compared the hydrographs to NEXRAD rainfall and quantified dry- and wet-season groundwater infiltration, base wastewater flow, and rainfall-dependent I&I. This analysis allowed us to prioritize the lift station basins for field investigation based on where the biggest return would be for the rehabilitation effort at a cost that was significantly less that flow monitoring. Results were corroborated with 10 permanent meter locations, metered winter water use, and known problems at lift stations. We then used short-term flow monitoring in some of the larger basins to further identify specific locations that are most in need of rehabilitation for I&I flow reduction, using other data to also evaluate structural integrity and risk of failure. The Program is set up to have rolling priorities set 2-3 years in advance for field investigation – followed by targeted rehabilitation – so that each step can be properly planned and budgeted.
The Program team also developed level-of-service (LOS) criteria that consider the unique challenges that GRU faces, including being more influenced by groundwater infiltration than by rainfall-derived I&I. The LOS criteria are tied to key performance indicators (KPI), with assumptions, methods of measurement, frequency of measurement, regulatory and internal drivers, influencing factors, and potential solutions identified for each KPI. We also performed an economic analysis to determine at what point conveyance and treatment is more cost-effective than rehabilitation, understanding that the collection system degradation is an ongoing process. The economic analysis was also used to refine the LOS criteria to ensure that the criteria are affordable.
Jones Edmunds provided the New River Solid Waste Association (NRSWA) with engineering services to modify the closure design and permit the closure with an exposed geomembrane cover (EGC) for the New River Regional Landfill (NRRL). The design and permit modification modified the permitted traditional closure design. The project included preparing a substantial permit modification to address the changes to the side-slope closure for an EGC closure. We prepared and submitted a substantial permit-modification application in accordance with Rule 62-701, FAC, including preparing the required supporting calculations and documentation for constructing the EGC for the closure.
Jones Edmunds worked closely with the NRSWA and the Florida Department of Environmental Protection (FDEP) to develop an Alternate Procedures Application for an Exposed Geomembrane Landfill Closure. Based on FDEP’s approval of the Alternate Procedures Application, Jones Edmunds submitted to FDEP a solid waste operation and construction permit application for an Exposed Geomembrane Cover (EGC) closure project. FDEP granted approval of the EGC application – this was first approved EGC closure permit in Florida. The conditions of the permit stated that an EGC would be installed as final cover until the material strength reached its half-life, at which time the traditional 24 inches of soil cover would be installed over the EGC.
The EGC is being constructed in phases as the landfill reaches final elevations. The EGC closure project includes preparing the final grade slopes, installing the geosynthetic material, and constructing the toe-drain system. The EGC closure project also included an evaluation of the gas collection and control system (GCCS) in the closure area. Phase I of the EGG project is approximately 15 acres. For Phase I, Jones Edmunds provided construction assistance including preparing bid and contract documents and coordinating Construction Quality Assurance (CQA) material testing and providing full-time CQA resident observation during construction.
In alignment with NASA’s strategic goal to optimize capabilities and operations, KSC is in the process of divesting (demolishing) several obsolete and inefficient facilities. This project included the demolition of the old Headquarters Building (~440,000 SF) and Central Instrumentation Facility (~140,000 SF) and to reduce operational and maintenance costs at KSC. The project was also in support of the construction of the new Central Campus Complex.
The demolition task included supporting utility disconnections and alterations, hazardous material testing and coordination with NASA Environmental, and government support. The systems included water, wastewater, stormwater, gas, chill water, hot water, power, communications, and civil infrastructure. The design was coordinated with other improvements in the area to provide a seamless transition as NASA further develops the area into a Central Campus. During the construction phase, Jones Edmunds assisted NASA and provided industry expert support regarding PCB waste and disposal.
Jones Edmunds continues to provide engineering services during construction while the project shifts from the CIF demolition to the HQ Building demolition by reviewing shop drawings, responding to requests for information, attending construction progress meetings, making construction site visits, resolving unforeseen conditions, providing cost opinions, and will prepare as-built/record drawings.
Jones Edmunds provided landfill mining construction-phase services for a closed unlined Class I Landfill cell located at the Putnam County Central Landfill. The services provided include conducting a waste investigation; creating construction-level documents; and providing bid-level and contract administration services, geotechnical analysis and design, solid waste permitting, and resident observation services. To save the County money, Jones Edmunds coordinated closely with the County during landfill mining, allowing the County to provide full-time resident observation in-house with Jones Edmunds providing limited support as needed.
