Tim Geraghty, PE
Project Manager
Tim Geraghty brings more than 15 years of experience in the civil engineering industry, supported by a strong technical foundation in land surveying. Beginning his career as a surveyor provided him with a detailed, ground-level understanding of site conditions, regulatory requirements, and construction sequencing. This experience continues to inform his approach to civil engineering design.
Tim has extensive expertise in utility detailing and the modeling of wet utility systems, along with a strong working knowledge of construction methods and field practices. He applies this technical insight to complex design challenges, focusing on solutions that are practical, efficient, and constructible. His ability to anticipate construction impacts during the design phase helps streamline project delivery and reduce risk for clients and contractors alike.
Known for his collaborative approach, Tim brings a technical and analytical perspective to multidisciplinary project teams and thrives on solving project-specific challenges. He is committed to delivering designs that balance technical rigor with real-world application, ensuring long-term performance and maintainability.
Scott Miller, PE
Project Manager
Scott Miller brings more than a decade of experience working on federal civil engineering projects both across the DMV region and internationally. He manages a diverse range of project types. They range from small-scale redevelopments to large new developments, as well as conceptual studies through full construction implementation.
Scott’s technical expertise is rooted in stormwater management, particularly within Maryland’s regulatory framework, and advanced 3D grading. His strong project management skills have been a key asset on complex federal and embassy projects. Many of these are located overseas and require coordination across multidisciplinary teams and time zones.
Additionally, Scott has extensive experience working on the firm’s IDIQ contracts, successfully managing multiple task orders concurrently while maintaining quality, schedules, and compliance requirements.
