DAVENPORT served as a subconsultant on this design-build project, providing traffic and transportation engineering services. The project included roadway and intersection improvements along NC 172 in the vicinity of Marines Road/Harvey Street and Munro Road, including modifications to an existing traffic signal and installation of a new traffic signal.
DAVENPORT's scope of work included preliminary horizontal roadway design, pavement marking and signing design, traffic management plans, tactical vehicle performance analysis, traffic signal design and coordinated signal system timing design services.
Timing was of extreme importance for this design-build project. DAVENPORT completed designs on time, while also meeting monetary expectations.
This project includes design-bid-build construction services for a new base entrance road for Camp Geiger and improvements to the entrance road at Marine Corps Air Station (MCAS) New River. The objective of this project is to provide for better road alignment, improved traffic flow, pedestrian safety and a distinct entrance to Camp Geiger.
DAVENPORT provided transportation engineering services including planning, analysis and design for the project. To better inform stakeholders in their determination of appropriate changes to the Camp Geiger/ MCAS Complex roadway network, an array of roadway and access improvement alternatives were evaluated in a Design Charrette process. By identifying more conducive traffic modifications, the team was able to recommend changes that would accommodate the impacts of roadway and access changes with analysis of forecasted future traffic volumes and follow up with further transportation design services.
DAVENPORT scope of work also included signal design services for a new signalized intersection including steel poles with mast arms, metal pole loading diagrams; design of a pedestrian activated flasher (RRFB-Rectangular Rapid Flashing Beacon) at the intersection of Curtis Road and A Street; development of signal quantities and cost estimates, and preparation of traffic signal technical specifications.
A detailed Transportation Management Plan (TMP) was developed to maintain traffic through the roadway improvement project during construction including quantities, cost estimates and technical specifications. The TMP included construction phasing and traffic control design to maintain traffic flow on New River Air Station and Camp Geiger including areas of construction related to Curtis Road widening, Church Street Extension, Campbell Street Extension, closure and conversion of A-Street to a greenway trail, and widening, demolition and tie-ins along Church Street. traffic control plans and pedestrian signal design.
The P-1346 site, located at Camp Lejeune, is proposed for the new construction of administrative-type buildings including three proposed structures and associated parking lots and storm water retention ponds. A portion of the property was previously developed as the Installation's brig. The structure and associated site improvements and appurtenances have been demolished. DAVENPORT, along with subconsultant CATLIN, is currently providing environmental services to determine whether soil, groundwater, and/or other media at the proposed construction site is negatively impacted (i.e., contaminated) at concentrations that would present unacceptable risks to construction workers or future land users. Our scope of work includes activities necessary for a historical assessment of the site, including site research and reconnaissance, soil borings and the collection of soil and groundwater samples.
The installation of monitoring wells and the collection of groundwater samples is based on the findings resulting from the soil sample analysis. The scope also requires a Vapor Intrusion Potential Study, including the installation of gas probes to collect soil vapor samples in areas selected for building facilities construction. This work will result in the submittal of an After Action Report providing conclusions and recommendations.
Home to the United States Marine Corps Forces Special Operations Command (MARSOC) Headquarters and The Lejeune Weapons Training Battalion, Stone Bay is a satellite facility located near Sneads Ferry, NC. Resting on the south side of Camp Lejeune and separated from main side by the New River, the core capabilities of the Stone Bay Facility are direct action, special reconnaissance, foreign internal defense, counter terrorism, information operations and unconventional warfare. As a result of an expected increase in the number of Marines from 500 to 2700, Stone Bay was undergoing significant growth and expansion.
This project included the widening of Dixon-Sneads Ferry Road (NC Route 210), a new ½ mile Connector Road with a multi-use path connecting to Rifle Range Road, vehicular and pedestrian bridges, and the requisite supporting infrastructure.
As a subconsultant, DAVENPORT provided transportation engineering services including a transportation impact analysis and corridor study which included an internal intersection analysis comparing a traffic signal versus roundabout intersection. DAVENPORT also provided design charrette presentations to facilitate the development of design solutions while integrating the aptitudes and interest of a diverse group of stakeholders. Our scope of work also included 2 new traffic signal design plans, and 1 temporary construction traffic signal design plan. Other services included construction phasing, traffic control plans and pedestrian signal design.
During the removal of an existing waterline at the Construction Site P-1268 (the future site of proposed Building G-484), possible petroleum impact was noted. One soil sample was collected from the base of the excavation and analyzed confirming a petroleum impact at the subject site.
Groundwater laboratory analytical results Subsequent to the soils removal action revealed petroleum concentrations in the shallow aquifer above the 2L GWQS in the groundwater sample collected from the “hotspot” well, installed at the approximate center of the former excavation. All additional groundwater samples collected from the surrounding wells indicated shallow petroleum impacted groundwater had been delineated horizontally to an area roughly the same size as the excavated area which was approximately 20 feet by 30 feet. DAVENPORT, along with subconsultant CATLIN, provided professional services necessary to assist Camp Lejeune with a goal of cleaning up detected contaminated groundwater beneath the site. In an effort to clean up the impacted shallow groundwater the remediation action was conducted through the construction of injection wells, and the placement of an Oxygen Release Compound (ORC) product within the defined area of groundwater contamination. The goal of the ORC compound is to greatly enhance the natural attenuation occurring at the site. Our scope of work included activities necessary for the implementation of the remedial action plan in order to bring the levels of detected targeted compounds in the groundwater to levels below the North Carolina 2L Groundwater Quality Standards (GWQS). These activities included a work plan to be completed with a proposed schedule of completion, all field work required for the installation of injection wells and ORC use, and an after action report detailing the injection well activities, and the completed injection results.
Located in Jacksonville, NC, Camp Lejeune holds five major Marine Corps commands and one Navy command supported by 43,100 military and 4,861 civilian personnel. Camp Lejeune has an aggressive environmental program to protect and conserve air, land, surface waters, groundwater, and other natural resources. However, to maintain combat ready units, Camp Lejeune utilizes large capacity fuel storage tanks, above and below grade piping, fuel pump stations and dispensing systems to store a variety of non-persistent oils such as jet propulsion fuel grade 5 (JP-5), automotive gasoline, diesel fuel, and heating oil. The Marine Corps is conducting groundwater remediation activities at various sites to address oil leaks from storage tanks & pipelines.
DAVENPORT/CATLIN is providing professional services necessary to assist Camp Lejeune with the management of their Petroleum Storage Tank Program. The specific tasks of this program vary but the overall goal is to identify, clean and monitor sites contaminated by past waste disposal and spills. At Marine Corps Base Camp Lejeune, the cleanup of hazardous waste disposal sites is not only required for compliance with federal and state regulations, it is essential for military preparedness and long-term sustainability of the base. The scope of this ongoing effort includes developing the annual Sampling Plan, reviewing and preparing Annual Monitoring Reports, and preparing the HPFF Bio-Pulse Evaluation Report. It is also our responsibility to lead monthly and quarterly conference calls with the entire team to discuss the overall effort.
At the end of the year the DAVENPORT/CATLIN team will submit the annual reports. The Annual Sampling Plan includes researching each active remediation site, monitoring and providing specific recommendations for gauging and sampling at each site in accordance with the Program Strategy Plan along with a site map of the well monitoring network. The Annual Monitoring Report includes detailed information on, current monitoring, free product removal, soil remediation and groundwater remediation as well as receptors. The receptor information includes water supply well, public water supplies, surface water, wellhead protection areas, and deep aquifers in region.
DAVENPORT facilitated a public involvement session for the impacted neighborhood and surrounding area by developing and maintaining a mailing list of the affected property owners and providing notice of the scheduled meetings. DAVENPORT prepared for and facilitated the public meeting to present the conceptual design for the roadway improvements and in addition prepared summary notes for distribution to WSDOT and NCDOT. The DAVENPORT staff interviewed and discussed current impacts with a purpose of identifying project issues and constraints foreseen by impacted property owner and shared this information with those reviewing and possibly modifying the design to develop a project consensus.
DAVENPORT served as a subconsultant on this project, providing traffic engineering services related to operational improvements needed to an intersection on Parachute Tower Road due to the design build construction of a new BEQ and Armory Complex.
The project involved realignment of an existing T-intersection. DAVENPORT's scope of services included review of the original alignment design concept and preparation of a preferred preliminary design.
The preferred design was developed with consideration for maximizing safety and efficiency; matching existing features (such as roads, structures, etc.); minimizing environmental impacts, property impacts, overall construcion costs; and establishing suitable access for properties within the project limits. Our recommended/preferred design alternative utilized the standard right turn lane design which keeps right turning movement ajacent to through lanes. DAVENPORT provided a pros and cons narrative summarizing the advantages and disadvantages of the standard right turn lane design, as compared to the originial channelized right turn lane design.
Other services included a transportation management plan, and pavement marking and signing design.
