MD 32/Linden Church Road Interchange Design-Build Howard County, MD
RK&K served as the Lead Designer on the Design-Build Team for this project which included the replacement of an at-grade intersection between MD 32 and Linden Church Road with a new grade separated diamond interchange. The project included design and construction provisions for the future dualization of MD 32 to a four-lane roadway with grass median. RK&K was responsible for all design, including geometrics, plans, profiles, typical sections, superelevation, geotechnical, pavement, maintenance of vehicular and bicycle traffic (coordinated with Howard County), bridge, signalization (permanent and temporary), landscaping, interchange lighting, pavement markings, drainage, environmental permitting, and utility coordination. RK&K was responsible for preparing for and participating in public and stakeholder outreach and meetings. RK&K partnered, coordinated with, and obtained approvals from with SHA, Howard County, MDE, USCE, MDNR, and the utility companies. Design and construction of the improvements, including stormwater management, erosions and sediment control, culvert extensions, and maintenance of traffic, had to be carefully considered to stay within the constrained right of way and minimize/avoid impacts to natural resources. RK&K prepared a Transportation Management Plan (TMP) for the project, addressing work zone impacts; evaluating MOT alternatives including detours; and providing public information and outreach. Based on the TMP, RK&K developed a multiple phase maintenance of traffic plan that provided ample room for construction and maximized mobility for the traveling public during construction. While detours were unavoidable due to grade changes and constrained right of way, the duration of the detours were minimized, access to driveways was maintained, and emergency vehicles access was carefully coordinated. SUCCESSFUL METHODS, APPROACHES, AND INNOVATIONS Schedule – In order to meet the contract completion date, RK&K developed multiple design packages and a schedule that included early release of grading packages and coordinated with utility companies to avoid impacts wherever possible. The schedule carefully considered the time needed QA/QC, SHA reviews, stakeholder reviews, and permitting. The project was completed on-time considering SHA granted extensions.
Mobility – RK&K’s development of the Traffic Management Plan and attention to detail during implementation allowed for maximum mobility (both vehicular and bicycle) during construction. The duration of detours, and the impact on residents and the traveling public, was minimized through careful design, coordination and notification of local residents, SHA, Howard County, and emergency services.
ROW and Environmental Resources – RK&K’s attention to detail and collaboration with the contractor allowed all improvements to be contained in the dedicated right-of-way. The LOD was significantly reduced, with avoidance and minimization of impacts to resources achieved by optimizing geometry, careful consideration of grading, application of traffic barrier, and optimization of the SWM and cross culvert design. Permitting needs were carefully tracked, and environmental documents were prepared in form of Mods to illustrate all that LOD’s were either reduced or eliminated at environmental areas including WUS, wetlands, floodplains, buffers, streams, forests, etc.
Design Excellence – Design of MD 32 and safety grading, bike lanes and secondary roads exceeded the minimum RFP, AASHTO and SHA criteria. Solid QA/QC processes, regular meetings, partnering, and an emphasis on coordinating with stakeholders ensured that the design meet not just the RFP requirements but also client and stakeholder expectations. RK&K and the contractor collaborated on a regular basis to ensure the design plans were constructible, thereby reducing delays once construction commenced.
RELEVANCE OF WORK TO THE PROJECT
The MD32/Linden Church Road Interchange Design-Build is within the limits of the Project. By using the same staff for both projects, RK&K’s familiarity with the design and construction of the existing roadway and site specific issues is unmatched. We understand how the existing interchange was designed to accommodate the future dualization of MD32. We already have relationships with the stakeholders, including utility companies that will be critical to the Project. In addition, the scope of work for the projects contains many of the same elements, including geotechnical conditions, pavement design, existing pavement rehabilitation, drainage, SWM, E&SC, natural resources, landscaping, lighting, culverts, utility coordination, and permit acquisition.

Winton, NC
RK&K served as the Lead Designer on the Design-Build Team for this design-build project which included dualization of approximately 7.1-miles of US 13/US 158 from US 158/NC 45 near Winton in Hertford County, NC to the US 158 Bypass in Tarheel in Gates County, NC. The project included the design and construction of a partially access controlled, 60 mph design speed, 4-lane divided facility with a 30-foot to 46-foot median width. An interchange was provided at the US 158/NC 45 intersection while directional crossovers with median U-Turns were provided elsewhere to improve the safety and traffic flow along the US 13/US 158 corridor. New bridges were provided over the Chowan River, Buckhorn Creek, and on US 13 over US 158. As Lead Designer, RK&K was responsible for all design services required for the project including roadway design; hydraulic design; maintenance of traffic; cross culverts; storm water management; erosion and sediment control; structures design; traffic control and pavement markings; signing and traffic signal design; permit preparation and application; utility coordination and relocation design; public involvement; subsurface investigations and foundation design; supplemental surveys; subsurface utility exploration; temporary pavement design; and right-of-way acquisition. Maintenance of traffic was a primary element of this project, as traffic on the existing two lane roadway had to be maintained in a safe manner with minimal impacts while constructing the new lanes. This was further complicated by the need to maintain existing cross road traffic while constructing the extensive concrete channelization islands and turn-outs that were part of the ultimate design to address traffic operations and safety. RK&K collaborated with the contractor to identify means, methods and phasing that would allow the work to proceed in a timely fashion while meeting NCDOT’s expectations for mobility and safety. As part of a larger program of improvements to US13/US 158, the work completed under this project was required to be compatible with a future extension of the dualization. The interim transition from the new 4 lane roadway to the existing 2 lane roadway was carefully considered from a design safety and future compatibility standpoint. SUCCESSFUL METHODS, APPROACHES, AND INNOVATIONS Schedule – Due to the fact that numerous utilities were present, our team engaged a full-time utility coordinator to ensure timely coordination, protection and/or relocation of all distribution and transmission lines. This allowed the utility relocations to occur in a timely and seamless manner for construction to stay ahead of schedule.
Mobility – The contractor, owner and stakeholders were engaged interactively in the preparation of the maintenance of traffic plans. This ensured that all parties understand the impacts to traffic and that the contractor supports the maintenance of traffic plan and will execute it appropriately during construction. The existing two lanes of traffic was maintained at all times, and detours/delays associated with connections to intersecting roadways were minimized.
ROW and Environmental Resources – The RK&K Team was responsible for right-of-way acquisition of 76 parcels including 28 relocations on this project. Our team used the opportunity to minimize the amount of right of way necessary, thereby accruing savings to NCDOT while also accelerating schedule by reducing the number of right of way acquisitions. We also scheduled and phased work packages to allow construction work to proceed before all property was available.
Design Excellence – Through the use of a rigorous design QA/QC plan, careful selection of designs staff, as well as partnering with NCDOT and stakeholders to ensure expectations are well understood, the vast majority of our submittals on this project resulted in minor comments. This allowed work to proceed without resubmittals, which was critical to obtaining the necessary environmental permits in a timely manner. In addition, thorough verification of NCDOT provided surveys resulted in discovery of inaccuracies that were easily corrected during design, but would have created delays and rework during construction.
RELEVANCE OF WORK TO THE PROJECT
This project includes the dualization widening of an existing roadway similar in nature to the MD32 – MD108 to Linden Church Project, including the need to coordinate with adjacent communities, maintain mobility during construction, and obtain environmental permits and utility clearances in a timely manner to allow for an accelerated construction schedule. This project also required that RK&K work as an integrated team with the contractor to sequence design and construction work packages in coordination with the right of way acquisition, utility work, maintenance of traffic requirements, and permitting timeframes in order to meet the aggressive project schedule. Also similar to MD32 – MD108 to Linden Church Project, this contract required compatibility with future extension of the upgraded roadway.

PROJECT EXPERIENCE
WALNEY ROAD WIDENING AND BRIDGE REPLACEMENT DESIGN-BUILD, $12M ( FAIRFAX COUNTY, VA ) – As Design-Build Project Manager, Tom led the VDOT and utilities partnership and overcame delays from long leads for special cable, splicing crew availability, and weather by phasing utility construction and supporting utility work with clearing and grubbing, ESC, and MOT support to bring the project back to schedule. The project widened Walney Road from two to four-lanes and replaced an existing bridge utilizing a four-month road closure and detour through a highly commercial area with daily commuter traffic of 21,000 vehicles per day. The detour received less than 10 public comments and the duration was minimized by one month.
MD 404 DUALIZATION DESIGN-BUILD $104M ( TALBOT COUNTY, MD ) – As Design-Build Coordinator, Tom is part of the JV Team for the roadway dualization and widening of MD 404. Tom met biweekly during the design process to ensure the timely approval of permits within one week of their scheduled dates to adhere to the strict construction schedule. The roadway includes 12- foot lanes, 4-foot paved inside shoulders, 10-foot paved outside shoulders, and a 34-foot median with traffic barrier protection. Partial acceleration/ deceleration lanes were provided and unprotected left turns will be eliminated with “J” Turns and Maryland “T” intersections.
COUNTY, VA ) – As Design-Build Project Manager, Tom worked closely with the Designer to develop a phased MOT construction approach that balanced the interaction between vehicles and pedestrians and prioritized through movements. This project upgraded the loop ramp from Fairfax County Parkway onto Fairfax County Parkway/Franconia- Springfield Parkway by adding a free single right turn lane creating a dual lane loop ramp. Scope of work included median improvements, soils remediation, retaining wall construction, utility coordination, and permit acquisition. TEMPLE AVE REALIGNMENT AND I- INTERCHANGE IMPROVEMENTS DESIGN-BUILD, $13M ( CHESTERFIELD COUNTY , VA ) – As Pre- construction Manager, Tom worked closely with the Design Manager, VDOT, and the City. He was able to mitigate a significant project risk by developing a design and construction approach that accommodated the construction of a Kroger Superstore adjacent to and concurrent with the VDOT design-build Project. He directed the incorporation of a single faced temporary wire wall into the MOT design to expedite construction, minimize congestion, and fast-track project completion. The scope of work included roadway realignment, road widening, and interchange ramp modifications, and roundabout implementation.

US 113 Dualization (Phase 3) Design-Build Project
Allan Myers is serving as the Design-Builder and Lead Contractor on this SHA project which includes partial realignment and upgrade 4 miles of US 113. The project is located south of Berlin, which begins North of Massey Branch and continues to Five Mile Branch Road. The project consists of the design and construction of two additional lanes along the existing US 113 alignment to create a dual four-lane divided highway. It also includes the new service roads to maintain access to residential and commercial properties. Roadway improvements include new pavement and pavement rehabilitation of existing roadways and shoulders, closed/open drainage systems, stormwater management (SWM) facilities, roadway intersection lighting, signing & pavement markings, and culvert extensions and/or replacement. The Myers Team was awarded the project based on a “best value selection” process and a total bid price of $32.1M. Currently, design is approximately 75% complete and Stage 1 construction, including clearing and grubbing, erosion and sediment controls, and rough grading the northern half of the project, is approximately 80% complete. This summer, work will be finished on Stage 2 which includes similar work to Phase 1 on the southern half of the project as well as the installation of large diameter storm drain crossings. SUCCESSFUL METHODS, APPROACHES, AND INNOVATIONS Schedule – Myers construction staff finalized the sequence of construction immediately after project award to allow work to begin as soon as possible while still providing the design team with sufficient time to plan and develop the design. The project was staged the project in the minimum number of stages (five) and divided into two halves (northern and southern) to progress staged construction in sequence with utility clearance and the progression of right-of-way (ROW) acquisition. Myers included rough and final grade phases as well as created separate plans for key work areas such as large storm drains. Strong coordination with project stakeholders has shortened the Railroad to embargo by 3 months. Coordination with the District Utility Engineer and Utility Companies (Verizon, Maryland Broadband Cooperative, Choptank Electric, and Delmarva Power) has included pre-construction meetings so that utility clearance will not impede the roadway work. Mobility – Through the use of a Maryland ‘T’ intersection, as a presented and approved ATC, Myers were able to enhance both safety of the intersection of Basket Switch Road and improve the multi-modal operations. The Myers Team was able to meet with property owners to minimize the impact of access to their farms and coordinate with planting schedules to make the best plan of action for all parties. Myers also coordinated with SHA and internal Public Relations teams to notify residents of disturbances on a monthly basis so they could plan accordingly. An integrated U- turn movement at Newark Road North connection reduces NB vehicles’ trip distance to head SB by three miles. ROW and Environmental Resources – Multiple features of the US 113 project come together to support a facility that is in sync with the environment and offers low-maintenance benefits. Myers is phasing construction for separate areas of the Project with required SWM design for that section. In that way, the SWM permit can be obtained for each phase prior to construction. In addition an emphasis has been put on making sure scheduled construction does not affect regulations regarding live streams such as storm drain crossings. Additional subsurface investigation is being utilized to narrow down the areas and depths of the water table to avoid erosion at pipe outfalls and fill slope failures in terms of maintenance concerns.
Design Excellence – The design team considered existing conditions, material selection, construction methods, future rehabilitation activities, and overall service life provided to the pavement network. Based on our understanding, we prepared an approved ATC where savings are achieved by reducing the thickness of the Hot-Mix Asphalt base without hindering the essential functions, characteristics, or expected performance of the project. All pavement elements including the rehabilitation sections meet or exceed the performance criteria in terms of structural capacity, skid resistance, visual appearance and ride quality for long-term maintenance.
RELEVANCE OF WORK TO THE PROJECT
US 113 Phase 3 is a similar project to MD 32 in scope due to length of the project, earthwork, pavement construction, existing pavement rehabilitation, drainage, stormwater management, erosion & sediment control, landscaping, signing and marking, intersection/interchange lighting, construction of small structures such as culverts, and utility coordination. The majority of this construction was to produce an additional two lanes to create a four lane divided highway, also similar to what is required for MD 32.

I-95 at Contee Road Interchange Design-Build Project
Allan Myers served as the Design-Builder and Lead Contractor on this SHA project which included design and construction of an urban arterial roadway and its grade separated connection with I-95 using a partial cloverleaf interchange configuration. Contee Road (Konterra Drive) was constructed parallel to the north and replace the existing Van Dusen Road and its crossing over I-95. The interchange connects within the I-95 collector-distributor (CD) roadway system between MD 198 and the Intercounty Connector (ICC) - MD 200. The project limits along Konterra Drive are from east of the Van Dusen Road intersection to approximately 0.5 mile west of Sweitzer Lane for a distance of approximately 1¼ miles. The work included constructing a 4-span bridge over I-95, two interchange directional ramps and two cloverleaf ramps, and the relocated at-grade connections of Sweitzer Lane and Van Dusen Road to Konterra Drive. The project required close coordination with several adjacent state, county, and private contracts. The Myers Team applied innovative and cost-effective solutions that resulted in over $2 million in cost savings. These solutions included reducing bridge costs and refining roadway geometrics and SWM features to eliminate significant earthwork and pavement reconstruction, construction staging/sequencing simplification, minimize utility impacts, and reduction of impacts to environmental features. The I-95 at Contee Road Interchange Design-Build Project was well-received by stakeholders and exemplified a partnership in design-build delivery while meeting the Owner’s budgetary and scheduling needs and the future needs of the region and users. SUCCESSFUL METHODS, APPROACHES, AND INNOVATIONS Schedule – The completion of the new Konterra Road Bridge and the demolition of the existing Van Dusen Bridge over I-95 allowed for the completion of the ICC’s CD Roadways with I-95 was vital to the success of Project. Myers accelerate construction to provide completion of the new bridge 4 weeks ahead of schedule. Mobility – No traffic incidents occurred with the traveling public during construction due to the Team’s proactive approach to safety and an additional Interim MOT Phase that properly maintained traffic for a water main betterment that conflicted with the proposed road alignment. Myers used detailed TMPs, limited construction access points, and isolated work to specific areas at a time in order to minimize safety risks to the traveling public. To further enhance access, safety and multi-modal features, the Myers Team updated the RFP conceptual design to comply with SHA’s revised Bicycle Policy & Design Guidelines by providing 6’ shoulders for marked bike lanes along the Konterra Drive and 6’ pocket lanes between the travel through lane and right turn lanes at the relocated at-grade intersections of Sweitzer Lane and Van Dusen Road. ROW and Environmental Resources – Incentives were achieved related to forest impact reduction and reforestation. The final completed project achieved 19.65 acres in actual forest impacts; a reduction of 4.78 acres. As a result of decreasing the Project footprint, increased area was available within right-of-way for on-site reforestation. The MD DNR permit requirement was to provide 14.52 acres of on-site reforestation and then 9.91 acres off-site by SHA for a 1:1 replacement of the 24.43 acres impacts. The final completed project achieved 27.57 acres of on-site reforestation. In addition, Waters of the US (WUS) impacts were decreased by 123 LF. The MDE/USCOE Joint Permit Application permitted WUS impacts at 1,366 LF based on SHA’s Concept/ Preliminary Design. The final completed project achieved 1,243 LF in actual WUS impacts. Design Excellence – ATCs were implemented which provided a shorter bridge with reduced number of girders, which accelerated the schedule and provided long-term maintenance benefits. Our progressive approach to SWM resulted in fewer facilities and lowered maintenance requirements. As we reduced the LOD and forest impacts, we provided a low-maintenance footprint relative to new plantings and grassed surfaces. Our design improved access for maintenance forces in the immediate I-95 corridor (and County Road system). Practical design decisions included adjusting the roadway profiles to reduce the vertical differential between existing and proposed roadways, allow for widening and overlay in lieu of full-depth reconstruction, and reduce traffic impacts for ramp construction. The flexible pavement design was based on the results of a deterministic Life Cycle Cost Analysis (LCCA) that took into account initial costs to the Administration, an evaluation of the potential available rehabilitation techniques, timing applications, and their anticipated costs, future design costs, and estimated user costs. RELEVANCE OF WORK TO THE PROJECT
This project was provided through SHA Design-Build delivery method and was extremely time-sensitive, due to the tie-in with the ICC D/E project which had very specific milestones. Due to accelerated construction Allan Myers developed an ATC to shorten the bridge over 1-95 by 82 feet resulting in completion four weeks ahead of schedule. Similar to MD 32 this was a high traffic asphalt roadway with comparable soil conditions to the new area of construction. Forest Impact Reduction goals were met by reducing project impact on this project resulting in 19.65 acres of actual forest impact and replacement of 24.43 acres impacts.

AND DESIGN-BUILD APPROACH
The Myers/RK&K Team will provide all of the design and construction services for the MD 32 improvements to provide a four-lane divided highway from MD 108 to north of Linden Church Road, a distance of approximately 3 miles. Our Team will also perform all necessary design and construction of roadways; culverts; walls; structures; H&H; temporary and permanent signing, lighting, signalization and pavement markings; ITS; landscape; utility coordination; pavement and geotechnical engineering; SWM including as-built certifications; E≻ data collection; reporting and permitting; maintenance of traffic; site maintenance; community relations; permits modifications; and mitigation as required by the Contract.
As a Team, we bring considerable of knowledge, expertise, and lessons learned from MD design-build contracts such as MD32/Linden Church, MD 404, and US 113 toward meeting the contract goals of schedule, mobility, right-of-way and environmental resources, and design excellence.
UNDERSTANDING OF THE PROJECT SCOPE
The proposed MD 32 improvements consists of dualizing MD 32 from MD 108 to north of Linden Church Rd to provide a four 12-foot lane divided highway with 4-foot inside and 10-foot paved outside shoulders. A 26-foot wide grass median with continuous traffic barrier is proposed. All existing pavement within the contract limits will be rehabilitated, and the new roadway may be concrete or asphalt pavement. The existing MD 32 ramps at Linden Church Road will require modifications to tie into the new roadway and will include full acceleration and deceleration lanes. The southern end of the Project will begin near the MD108 Bridge over MD 32. The northern limit of the Project will be north of the MD32 / Linden Church Road interchange. The design will also accommodate the future widening of MD 32 from the northern limit of this contract to I-70.
SWM / ESC : We understand that SHA has developed a concept design for SWM which is under review by SHA-PRD. The Myers/RK&K Team will be responsible for completing the three step process (concept, site development and final approvals) and obtaining approvals directly from SHA-PRD. We expect to construct pond facilities, primarily on the west side of MD 32, and that facilities such as bioswales, wet swales, and grass swales will likely be required on both sides of the roadway and in the median. Along MD 32, 6-feet of the existing pavement will be removed along the future median for the entire length of the Project, helping to offset the new impervious area. Our Team will prepare and permit E&SC plans through PRD.
Environmental Permitting: SHA anticipates approval of the NPDES NOI, Nontidal Wetlands & Water Permit, Section 404 Individual Permit, Reforestation Law Approval, and FEMA CLOMR prior to Award of the Contract. Our Team understands that we are responsible for any modifications to these permits, and that all agency coordination/permitting is to be conducted through the Administration. We will perform field visits to confirm resource limits, update wetland plates as required, and track avoidance and minimize measures and project commitments.

approach will ensure that all stakeholders are involved in the process from start to finish, and that expectations are understood by all parties.
GOAL 2-MOBILITY: Our Team will minimize delays during construction, and will specifically avoid and minimize the duration of any detours. We will perform our design and construction sequencing specifically to reduce impacts to the traveling public. Two examples of such measures are:
GOAL 3-RIGHT-OF-WAY AND ENVIRONMENTAL RESOURCES: We will minimize impacts to private property and environmental resources by applying practical design. Our Team will make adjustments to the horizontal\vertical alignments, safety grading, and traffic barrier placement to minimize impacts while fitting within the context of MD 32. We will continually investigate and document avoidance measure to reduce/eliminate impacts to floodplains, wetlands, forests, streams, buffers, historic properties and endangered species. These measures will include steepening slopes at sensitive areas, shifting or reshaping SWM ponds, adding w-beam and reducing the hinge width behind where allowed per standards, and extending headwall structures at the culverts. We will ensure that the footprint of SWM facilities are minimized and located such that the minimum number of property owners are impacted.
GOAL 4-DESIGN EXCELLENCE: Our Team will practice good judgment through execution, as well as sound decision-making within project constraints. RK&K has a history of design excellence, as evidenced by MDQI awards for the Charles St. Interchange and MD216. Our Team, including IDQM firm Wallace Montgomery, understands that the key to design excellence is a collaborative, integrated effort between all parties, including SHA and the stakeholders. We have a history of working together on major projects such as MD 404 design-build, and we understand the level of effort that is required to produce quality plans. We will foster a professional environment that promotes solid engineering judgment, places a high value on quality, and ensures SHA and stakeholder expectations are exceeded. All released for construction documents will undergo design QA/QC review, IDQM review, and SHA audit/review as appropriate.
