Roadway Geometric Design
Skill Set: Roadway / Geometric Design
Highway design elements such as horizontal and vertical geometrics and roadside grading can impact overall project costs as well as construction time frames. Adverse impacts associated with roadway geometrics could include, problematic excavation due to rock, or unsuitable materials requiring excavation and backfill, to impacts to neighboring properties among others. Vertical and horizontal alignments can often result in utility impacts which should be considered during geometric layout. Design guidelines allow for flexibility during design. The designers challenge is to meet state and national design standards while minimizing adverse impacts overall. If all of these elements can be brought together in an efficient manner, the result should be a construction time frame that is as timely as possible with minimal adverse impacts.
Goals for Skill Set:
- Evaluate the horizontal and vertical geometrics to assess efficacy of construction both overall and during various phases of Maintenance of Traffic.
- Evaluate the horizontal and vertical geometrics with regard to access to the surrounding properties during construction.
- Evaluate the design geometrics with regard to impacts to neighboring properties.
- Review all design elements to assure that necessitated utility relocations have been minimized to the greatest extent possible.
- Review key design elements to assess if there are any means of accelerating construction through innovative design techniques.
- Review design elements with regard to the need for permits and the possibility of minimizing or eliminating.

Skill Set: Traffic / ITS / Safety
Traffic management techniques both during construction and in the completed facility will be critical to the overall success of the project. All innovative techniques that will aide in improving safety, traffic flow, communication and overall speed of construction should be thoroughly reviewed for possibilities. Efficiency in communicating to local elected officials, emergency service providers, the traveling community, and local businesses regarding traffic shifts/detours/restrictions and maintenance of traffic phases during construction will help to minimize impacts. Information systems to communicate via the internet and media should be explored. Incident management systems should also be assessed for potential benefit for this project.
Goals for Skill Set:
- Review Maintenance of Traffic Plans for opportunities to improve traffic flow and eliminate phases or shorten durations while maintaining safety practices.
- Assess pedestrian and biker safety, mobility and accessibility during construction.
- Consider truck detours during heavy construction periods.
- Consider working with businesses to coordinate truck business deliveries to non construction hours.
- Assess the benefits of a Public Involvement Liaison and Campaign during construction.
- Review construction phases for work zone safety.
- During construction, consider alternate route detours or elimination of certain movements to maximize work zone areas.
- On hand field resources for Incident Management; special event planning during construction and post construction.
- Utilize ITS into construction phasing.
- Assure current technology for traffic control devices ( signs, signals, VMS, arrow panels, portable signs).
- Post construction – Traffic Demand Management (hov, mass transit, car/vanpooling, work with local business to encourage flex time, telecommuting, etc.)

Skill Set: Structures
The tunnel carrying Randolph Road beneath MD 97, with WMATA rail tunnels located approximately fifty feet below the existing intersection is the focal point of this project. Any effective means of accelerating the construction of both the tunnel and associated retaining walls could have the resultant effect of accelerating the overall project construction period. Review of standard design and construction practices should be performed. Prefabrication or pre-ordering of materials when applicable to avoid delays should be reviewed. Partnering between the owner and the contractor may aide in communications and expediting construction and should be considered.
Goals for Skill Set:
- Design concepts should consider availability of materials. Are there any long lead items?
- Construction areas will be constrained in this tightly urbanized area. Staging areas and accessibility of those areas should be assessed.
- Design concepts should consider the use of early strength concrete or precast materials for tunnel and retaining walls.
- Evaluate impacts to utilities associated with structure foundations.
- Assess the stages of construction and evaluate the possibility of reducing stages.
- Should construction management be considered as a means of improving construction efficiency, owner/contractor partnering and reduction of delay?
- Are there other new types of construction materials and/or techniques that could be used on this project that would speed construction?
