Core Responsibilities

Primary Functions

Take full ownership of the geometric design for urban and rural highway projects, meticulously developing horizontal and vertical alignments, superelevation, and cross-sections to ensure driver safety and comfort.
Lead the comprehensive analysis and design of storm drainage systems, including the hydraulic modeling of culverts, storm sewers, and detention/retention ponds to manage stormwater runoff effectively.
Develop complete and detailed sets of construction drawings (PS&E - Plans, Specifications, and Estimates), ensuring every detail is captured for a seamless bidding and construction process.
Create and manage intricate 3D corridor models using advanced design software like OpenRoads Designer or Civil 3D, which serve as the digital backbone for the entire project lifecycle.
Conduct thorough design calculations for roadway geometrics, earthwork volumes, drainage systems, and structural components, providing a robust analytical foundation for all design decisions.
Meticulously prepare and review detailed construction cost estimates and quantity take-offs, providing clients with accurate budget forecasting and project cost control.
Author and compile comprehensive technical reports, feasibility studies, and design documentation that clearly communicate complex engineering concepts to clients, stakeholders, and regulatory agencies.
Ensure all design work rigorously adheres to the latest standards and guidelines from authorities such as AASHTO, FHWA, and state-specific Departments of Transportation (DOT).
Masterfully develop detailed Maintenance of Traffic (MOT) and traffic control plans that ensure worker and public safety during all phases of construction.
Actively coordinate with a wide array of disciplines, including structural, geotechnical, environmental, surveying, and utility teams, to create a fully integrated and conflict-free design.
Serve as a key technical liaison during client meetings and public involvement sessions, adeptly presenting design concepts and addressing concerns from stakeholders with clarity and confidence.
Perform detailed reviews of shop drawings and contractor submittals during the construction phase to guarantee compliance with the approved design plans and specifications.
Proactively respond to Requests for Information (RFIs) from contractors, providing timely and accurate clarifications to prevent construction delays.
Conduct on-site field visits to assess existing conditions, verify survey data, and monitor construction progress, bridging the gap between the design office and the field.
Spearhead the development of right-of-way and easement acquisition plans, coordinating with legal and real estate professionals to secure the necessary land for a project.
Oversee the design of pavement markings, signage, and roadway lighting systems to enhance navigational clarity and safety for all road users.
Assist project managers in developing project scopes, schedules, and budgets, contributing to the successful proposal and management of new engineering work.
Analyze and interpret complex survey data, topographic maps, and geotechnical reports to inform a practical and context-sensitive design approach.
Mentor and provide technical guidance to junior engineers and EITs, fostering their professional growth and ensuring the quality of their work contributions.
Investigate and incorporate innovative design techniques and sustainable materials to improve project resilience, reduce environmental impact, and deliver long-term value.

Secondary Functions

Support ad-hoc data requests and exploratory analysis related to traffic patterns, material performance, or construction data.
Contribute to the organization's continuous improvement efforts by refining design standards, workflows, and best practices.
Collaborate with business development teams to provide technical insights and content for project proposals and client presentations.
Participate in sprint planning and agile ceremonies if working within a firm that has adopted these methodologies for project delivery.
