LT provided civil, electrical, and structural engineering services for the transit center improvements. The team developed pavement repair and replacement plans, revised site grading, designed the K-rated bollard systems, and coordinated the supporting electrical and infrastructure requirements.
LT also prepared traffic-pattern layouts and maintenance-of-traffic plans to guide buses and passengers safely through the facility during construction. The drawings were coordinated and permitted in accordance with Department of Defense, WMATA, federal, state, and local requirements.
Because the transit center needed to remain operational, the construction sequence was as important as the permanent design. LT developed maintenance-of-traffic plans that allowed work to proceed in phases while minimizing delays for buses and the commuting public.
High-strength concrete was introduced in heavily traveled areas to provide greater durability under frequent bus traffic. Regrading addressed areas of poor drainage while improving vehicle movement through the facility.
The bollard design brought together structural foundations, power, controls, and pneumatic and hydraulic systems within an active transportation environment. Close coordination among disciplines and reviewing agencies allowed the improvements to strengthen pavement performance, pedestrian safety, drainage, and traffic flow without compromising the center’s daily operations.
